+-- GET GOING
+--
+-- You need to copy this file over lexer.lua. In principle other lexers could work
+-- too but not now. Maybe some day. All patterns will move into the patterns name
+-- space. I might do the same with styles. If you run an older version of SciTE you
+-- can take one of the archives. Pre 3.41 versions can just be copied to the right
+-- path, as there we still use part of the normal lexer. Below we mention some
+-- issues with different versions of SciTE. We try to keep up with changes but best
+-- check careful if the version that yuou install works as expected because SciTE
+-- and the scintillua dll need to be in sync.
+--
+-- REMARK
+--
+-- We started using lpeg lexing as soon as it came available. Because we had rather
+-- demanding files and also wanted to use nested lexers, we ended up with our own
+-- variant. At least at that time this was more robust and also much faster (as we
+-- have some pretty large Lua data files and also work with large xml files). As a
+-- consequence successive versions had to be adapted to changes in the (at that time
+-- still unstable) api. In addition to lexing we also have spell checking and such.
+-- Around version 3.60 things became more stable so I don't expect to change much.
+--
+-- LEXING
+--
+-- When pc's showed up we wrote our own editor (texedit) in MODULA 2. It was fast,
+-- had multiple overlapping (text) windows, could run in the at most 1M memory at
+-- that time, etc. The realtime file browsing with lexing that we had at that time
+-- is still on my current wish list. The color scheme and logic that we used related
+-- to the logic behind the ConTeXt user interface that evolved.
+--
+-- Later I rewrote the editor in perl/tk. I don't like the perl syntax but tk
+-- widgets are very powerful and hard to beat. In fact, TextAdept reminds me of
+-- that: wrap your own interface around a framework (tk had an edit control that one
+-- could control completely not that different from scintilla). Last time I checked
+-- it still ran fine so I might try to implement something like its file handling in
+-- TextAdept.
+--
+-- In the end I settled for SciTE for which I wrote TeX and MetaPost lexers that
+-- could handle keyword sets. With respect to lexing (syntax highlighting) ConTeXt
+-- has a long history, if only because we need it for manuals. Anyway, in the end we
+-- arrived at lpeg based lexing (which is quite natural as we have lots of lpeg
+-- usage in ConTeXt). The basic color schemes haven't changed much. The most
+-- prominent differences are the nested lexers.
+--
+-- In the meantime I made the lexer suitable for typesetting sources which was no
+-- big deal as we already had that in place (ConTeXt used lpeg from the day it
+-- showed up so we have several lexing options there too).
+--
+-- Keep in mind that in ConTeXt (typesetting) lexing can follow several approached:
+-- line based (which is handy for verbatim mode), syntax mode (which is nice for
+-- tutorials), and tolerant mode (so that one can also show bad examples or errors).
+-- These demands can clash.
+--
+-- HISTORY
+--
+-- The remarks below are more for myself so that I keep track of changes in the
+-- way we adapt to the changes in the scintillua and scite.
+--
+-- The fold and lex functions are copied and patched from original code by Mitchell
+-- (see lexer.lua) in the scintillua distribution. So whatever I say below, assume
+-- that all errors are mine. The ability to use lpeg in scintilla is a real nice
+-- addition and a brilliant move. The code is a byproduct of the (mainly Lua based)
+-- TextAdept which at the time I ran into it was a rapidly moving target so I
+-- decided to stick ot SciTE. When I played with it, it had no realtime output pane
+-- although that seems to be dealt with now (2017). I need to have a look at it in
+-- more detail but a first test again made the output hang and it was a bit slow too
+-- (and I also want the log pane as SciTE has it, on the right, in view). So, for
+-- now I stick to SciTE even when it's somewhat crippled by the fact that we cannot
+-- hook our own (language dependent) lexer into the output pane (somehow the
+-- errorlist lexer is hard coded into the editor). Hopefully that will change some
+-- day. The ConTeXt distribution has cmd runner for textdept that will plug in the
+-- lexers discussed here as well as a dedicated runner. Considere it an experiment.
+--
+-- The basic code hasn't changed much but we had to adapt a few times to changes in
+-- the api and/or work around bugs. Starting with SciTE version 3.20 there was an
+-- issue with coloring. We still lacked a connection with SciTE itself (properties
+-- as well as printing to the log pane) and we could not trace this (on windows).
+-- However on unix we can see messages! As far as I can see, there are no
+-- fundamental changes in lexer.lua or LexLPeg.cxx so it must be/have been in
+-- Scintilla itself. So we went back to 3.10. Indicators of issues are: no lexing of
+-- 'next' and 'goto <label>' in the Lua lexer and no brace highlighting either.
+-- Interesting is that it does work ok in the cld lexer (so the Lua code is okay).
+-- All seems to be ok again in later versions, so, when you update best check first
+-- and just switch back to an older version as normally a SciTE update is not
+-- critital. When char-def.lua lexes real fast this is a signal that the lexer quits
+-- somewhere halfway. Maybe there are some hard coded limitations on the amount of
+-- styles and/or length of names.
+--
+-- Anyway, after checking 3.24 and adapting to the new lexer tables things are okay
+-- again. So, this version assumes 3.24 or higher. In 3.24 we have a different token
+-- result, i.e. no longer a { tag, pattern } but just two return values. I didn't
+-- check other changes but will do that when I run into issues. I had already
+-- optimized these small tables by hashing which was much more efficient (and maybe
+-- even more efficient than the current approach) but this is no longer needed. For
+-- the moment we keep some of that code around as I don't know what happens in
+-- future versions. I'm anyway still happy with this kind of lexing.
+--
+-- In 3.31 another major change took place: some helper constants (maybe they're no
+-- longer constants) and functions were moved into the lexer modules namespace but
+-- the functions are assigned to the Lua module afterward so we cannot alias them
+-- beforehand. We're probably getting close to a stable interface now. At that time
+-- for the first time I considered making a whole copy and patch the other functions
+-- too as we need an extra nesting model. However, I don't want to maintain too
+-- much. An unfortunate change in 3.03 is that no longer a script can be specified.
+-- This means that instead of loading the extensions via the properties file, we now
+-- need to load them in our own lexers, unless of course we replace lexer.lua
+-- completely (which adds another installation issue).
+--
+-- Another change has been that _LEXERHOME is no longer available. It looks like
+-- more and more functionality gets dropped so maybe at some point we need to ship
+-- our own dll/so files. For instance, I'd like to have access to the current
+-- filename and other SciTE properties. We could then cache some info with each
+-- file, if only we had knowledge of what file we're dealing with. This all makes a
+-- nice installation more complex and (worse) makes it hard to share files between
+-- different editors usign s similar directory structure.
+--
+-- For huge files folding can be pretty slow and I do have some large ones that I
+-- keep open all the time. Loading is normally no ussue, unless one has remembered
+-- the status and the cursor is at the last line of a 200K line file. Optimizing the
+-- fold function brought down loading of char-def.lua from 14 sec => 8 sec.
+-- Replacing the word_match function and optimizing the lex function gained another
+-- 2+ seconds. A 6 second load is quite ok for me. The changed lexer table structure
+-- (no subtables) brings loading down to a few seconds.
+--
+-- When the lexer path is copied to the TextAdept lexer path, and the theme
+-- definition to theme path (as lexer.lua), the lexer works there as well. Although
+-- ... when I decided to check the state of TextAdept I had to adapt some loader
+-- code. The solution is not pretty but works and also permits overloading. When I
+-- have time and motive I will make a proper setup file to tune the look and feel a
+-- bit more than we do now. The TextAdept editor nwo has tabs and a console so it
+-- has become more useable for me (it's still somewhat slower than SciTE).
+-- Interesting is that the jit version of TextAdept crashes on lexing large files
+-- (and does not feel faster either; maybe a side effect of known limitations as we
+-- know that Luajit is more limited than stock Lua).
+--
+-- Function load(lexer_name) starts with _lexers.WHITESPACE = lexer_name ..
+-- '_whitespace' which means that we need to have it frozen at the moment we load
+-- another lexer. Because spacing is used to revert to a parent lexer we need to
+-- make sure that we load children as late as possible in order not to get the wrong
+-- whitespace trigger. This took me quite a while to figure out (not being that
+-- familiar with the internals). The lex and fold functions have been optimized. It
+-- is a pitty that there is no proper print available. Another thing needed is a
+-- default style in our own theme style definition, as otherwise we get wrong nested
+-- lexers, especially if they are larger than a view. This is the hardest part of
+-- getting things right.
+--
+-- It's a pitty that there is no scintillua library for the OSX version of SciTE.
+-- Even better would be to have the scintillua library as integral part of SciTE as
+-- that way I could use OSX alongside windows and linux (depending on needs). Also
+-- nice would be to have a proper interface to SciTE then because currently the
+-- lexer is rather isolated and the Lua version does not provide all standard
+-- libraries. It would also be good to have lpeg support in the regular SciTE Lua
+-- extension (currently you need to pick it up from someplace else). I keep hoping.
+--
+-- With 3.41 the interface changed again so it became time to look into the C++ code
+-- and consider compiling and patching myself, something that I like to avoid.
+-- Loading is more complicated now as the lexer gets loaded automatically so we have
+-- little control over extending the code now. After a few days trying all kind of
+-- solutions I decided to follow a different approach: drop in a complete
+-- replacement. This of course means that I need to keep track of even more changes
+-- (which for sure will happen) but at least I get rid of interferences. Till 3.60
+-- the api (lexing and configuration) was simply too unstable across versions which
+-- is a pitty because we expect authors to install SciTE without hassle. Maybe in a
+-- few years things will have stabelized. Maybe it's also not really expected that
+-- one writes lexers at all. A side effect is that I now no longer will use shipped
+-- lexers for languages that I made no lexer for, but just the built-in ones in
+-- addition to the ConTeXt lpeg lexers. Not that it matters much as the ConTeXt
+-- lexers cover what I need (and I can always write more). For editing TeX files one
+-- only needs a limited set of lexers (TeX, MetaPost, Lua, BibTeX, C/W, PDF, SQL,
+-- etc). I can add more when I want.
+--
+-- In fact, the transition to 3.41 was triggered by an unfateful update of Ubuntu
+-- which left me with an incompatible SciTE and lexer library and updating was not
+-- possible due to the lack of 64 bit libraries. We'll see what the future brings.
+-- For now I can use SciTE under wine on linux. The fact that scintillua ships
+-- independently is a showstopper.
+--
+-- Promissing is that the library now can use another Lua instance so maybe some day
+-- it will get properly in SciTE and we can use more clever scripting.
+--
+-- In some lexers we use embedded ones even if we could do it directly, The reason
+-- is that when the end token is edited (e.g. -->), backtracking to the space before
+-- the begin token (e.g. <!--) results in applying the surrounding whitespace which
+-- in turn means that when the end token is edited right, backtracking doesn't go
+-- back. One solution (in the dll) would be to backtrack several space categories.
+-- After all, lexing is quite fast (applying the result is much slower).
+--
+-- For some reason the first blob of text tends to go wrong (pdf and web). It would
+-- be nice to have 'whole doc' initial lexing. Quite fishy as it makes it impossible
+-- to lex the first part well (for already opened documents) because only a partial
+-- text is passed.
+--
+-- So, maybe I should just write this from scratch (assuming more generic usage)
+-- because after all, the dll expects just tables, based on a string. I can then
+-- also do some more aggressive resource sharing (needed when used generic).
+--
+-- I think that nested lexers are still bugged (esp over longer ranges). It never
+-- was robust or maybe it's simply not meant for too complex cases (well, it
+-- probably *is* tricky material). The 3.24 version was probably the best so far.
+-- The fact that styles bleed between lexers even if their states are isolated is an
+-- issue. Another issus is that zero characters in the text passed to the lexer can
+-- mess things up (pdf files have them in streams).
+--
+-- For more complex 'languages', like web or xml, we need to make sure that we use
+-- e.g. 'default' for spacing that makes up some construct. Ok, we then still have a
+-- backtracking issue but less.
+--
+-- Good news for some ConTeXt users: there is now a scintillua plugin for notepad++
+-- and we ship an ini file for that editor with some installation instructions
+-- embedded. Also, TextAdept has a console so that we can run realtime. The spawner
+-- is still not perfect (sometimes hangs) but it was enough reason to spend time on
+-- making our lexer work with TextAdept and create a setup.
+--
+-- Some bad news. The interface changed (again) in textadept 10, some for the better
+-- (but a bit different from what happens here) and some for the worse, especially
+-- moving some code to the init file so we now need some bad hacks. I decided to
+-- stay with the old method of defining lexers and because the lexer cannot be run
+-- in parallel any more (some change in the binary?) I will probably also cleanup
+-- code below as we no longer need to be compatible. Unfortunately textadept is too
+-- much a moving target to simply kick in some (tex related) production flow (apart
+-- from the fact that it doesn't yet have the scite like realtime console). I'll
+-- keep an eye on it. Because we don't need many added features I might as well decide
+-- to make a lean and mean instance (after all the license permits forking).
+
+-- TRACING
+--
+-- The advantage is that we now can check more easily with regular Lua(TeX). We can
+-- also use wine and print to the console (somehow stdout is intercepted there.) So,
+-- I've added a bit of tracing. Interesting is to notice that each document gets its
+-- own instance which has advantages but also means that when we are spellchecking
+-- we reload the word lists each time. (In the past I assumed a shared instance and
+-- took some precautions. But I can fix this.)
+--
+-- TODO
+--
+-- It would be nice if we could load some ConTeXt Lua modules (the basic set) and
+-- then use resolvers and such. But it might not work well with scite.
+--
+-- The current lexer basics are still a mix between old and new. Maybe I should redo
+-- some more. This is probably easier in TextAdept than in SciTE.
+--
+-- We have to make sure we don't overload ConTeXt definitions when this code is used
+-- in ConTeXt. I still have to add some of the goodies that we have there in lexers
+-- into these.
+--
+-- Maybe I should use a special stripped on the one hand and extended version of the
+-- dll (stable api) and at least add a bit more interfacing to scintilla.
+--
+-- I need to investigate if we can use the already built in Lua instance so that we
+-- can combine the power of lexing with extensions.
+--
+-- I need to play with hotspot and other properties like indicators (whatever they
+-- are).
+--
+-- I want to get rid of these lexers.STYLE_XX and lexers.XX things. This is possible
+-- when we give up compatibility. Generalize the helpers that I wrote for SciTE so
+-- that they also can be used TextAdept.
+--
+-- I can make an export to ConTeXt, but first I'll redo the code that makes the
+-- grammar, as we only seem to need
+--
+--   lexer._TOKENSTYLES : table
+--   lexer._CHILDREN    : flag
+--   lexer._EXTRASTYLES : table
+--   lexer._GRAMMAR     : flag
+--
+--   lexers.load        : function
+--   lexers.lex         : function
+--
+-- So, if we drop compatibility with other lex definitions, we can make things
+-- simpler. However, in the meantime one can just do this:
+--
+--    context --extra=listing --scite [--compact --verycompact] somefile.tex
+--
+-- and get a printable document. So, this todo is a bit obsolete.
+--
+-- Properties is an ugly mess ... due to chages in the interface we're now left
+-- with some hybrid that sort of works ok

+%D The calculator
+%D
+%D This document was made in 1998 as demonstration of widgets in \CONTEXT in \MKII.
+%D It has been adapted to run in \MKIV. Not many changes were needed. The macro
+%D definitions are layout a bit more readable and we use official scratch variables.
+%D
+%D The \JAVASCRIPT\ interpeter has changes and also became more strict. So, I
+%D reformatted the code bit and added some more semicolons and vars.
+%D
+%D We changed to font from a Helvetica lookalike to Dejavu but kept the colors as
+%D in the original. We also kept the \JAVASCRIPT\ and \METAPOST\ code (although
+%D we had to add some initalizations for \METAPOST\ due to the runtime graphic
+%D generation. I didn't check the functionality.
+%D
+%D Should I do it different nowaways? For sure. I might use layers of make nicer
+%D \METAPOST\ code but it's also a demonstration of how thinsg were done in 1998.

+    This calculator is stack based, which means that one enters values and
+    invokes an action that acts on the value(s) last entered. Subtracting 10 from
+    20 using (\Key {--} {sub}) for instance comes down to clicking:
+
+    \startnarrower\ss
+        10\quad in\quad 20\quad --
+    \stopnarrower
+
+    while calculating a sinus (\Key {sin} {sin}) results from entering:
+
+    \startnarrower\ss
+        .89\quad sin
+    \stopnarrower
+
+    The left column of fields (numbers) shows the Stack. One uses \Key {push}
+    {push} to push a value on the stack and \Key {pop} {pop} to remove a value.
+    Clicking \Key {new} {new} removes them all and the \Key {del} {del} button
+    can be used to undo the last entered digit. When a dyadic operation is
+    applied, the top value is used as~y. The \Key {grow} {grow} key toggles
+    between two different visualizations of the stack.
+
+    The stack is considerably larger than the screen representation suggests. In
+    the rare occasion that one encounters the message {\ss exhausted}, the amount
+    of stack entries already has totaled far beyond \MinLevel\ and one probably
+    already has forgotten what the values first entered represent.
+
+    The right column of fields reports the statistic calculations. By clicking on
+    the tag, one pushes the value on the Stack. The lower buttons are used to
+    reset~(\Key {new} {newn}), enter~(\Key {+} {addn}) and remove~(\Key {--}
+    {subn}) values to be taken into account when calculating those statistics.

+    This document is produced by \ConTeXt, a macro package written in \TeX. The
+    graphics are METAPOST graphics. The graphics, the PDF objects and the form
+    fields as well as JavaScript code were generated and inserted at run time.
+    Originally we used PDF\TeX\ and \MKII\ to process this document but this one
+    is done by \LUATEX\ and \MKIV. We kept the design and code original so that
+    it reflects how things were done (for readability we updated some \TEX\
+    definitions).

+%D This example dates from late 2001, and ws probaby made for some \TEX\ related
+%D meeting. It's a relative simple example that uses a few function from a general
+%D \JAVASCRIPT\ preamble. In fact forcing the \type {FieldStack} code into the
+%D is the only adaptation from \MKII\ to \MKIV\ (because we load on demand and here
+%D the code is ude sindirectly).
+%D
+%D Nowadays we could layers instead which is probably a bit more ligthweight than
+%D widgets. Also, we should actually synchronize the time but on the other hand, but
+%D on the other hand, now it's a sort of stopwatch.

+\startitemize
+\startitem
+    Of course the only way to deal with this nicely is by using runtime created

+\stopitem
+\startitem
+    So called \PDF\ literals can interfere badly with font switches at the \PDF\
+    level and are therefore very inefficient.
+\stopitem
+\startitem
+    In order to properly support effects at the font level, we need to be able to
+    inject the right \PDF\ code in a more clever way.
+\stopitem
+\startitem
+    Two new keys were added to the font file definition table: \type{width} and
+    \type {mode}. When set these inject a \PDF\ line width operation and trigger the
+    right rendering mode (backend).

+        We started using \METAPOST\ some two decades ago and immediately went
+        the \PDF\ route.
+    \stopitem
+    \startitem
+        We used special colors plus specials to communicate extensions, for instance
+        \CMYK\ colors and shades.
+    \stopitem
+    \startitem
+        This mechanism was stepwise improved and extended. Some mechanisms, like texts,
+        needed an extra pass.
+    \stopitem
+    \startitem
+        When we moved to \LUATEX\ and \MPLIB\ we started using pre- and postscripts to
+        carry information with the paths.
+    \stopitem
+    \startitem
+        Currently we use a bit of \LUA\ from within \MPLIB\ to communicate during the
+        \METAPOST\ run with \CONTEXT. This permits cleaner interfaces.

+\BC domain  \NC The range over which the colors run, with a minimum of 0 and maximum of 1. \NC \NR
+\BC color   \NC A color to start from and one to end with, we default from black to white. \NC \NR
+\BC type    \NC The shading can be linear or circular. \NC \NR

+
+For a {\bf linear} shade the centers are the lower left and upper right corners,
+for a circular shade it's the center of the path. For a {\bf circular} shade the
+radius runs from zero to the maximum distance from the center as determined by
+the boundingbox.
+
+The vector is used as follows: the first coordinate (xpart) determines the point
+on the path where we start, the second coordinate (ypart) the point on the
+path where we end.

+
+This manual is about integrating graphics your document. Doing this is not really
+that complex so this manual will be short. Because graphic inclusion is related
+to the backend some options will discussed. It's typical one of these manuals
+that can grow over time.
+
+\stopsubject
+
+\startsubject[title=Basic formats]
+
+In \TEX\ a graphic is not really known as graphic. The core task of the engine is
+to turn input into typeset paragraphs. By the time that happens the input has
+become a linked list of so called nodes: glyphs, kerns, glue, rules, boxes and a
+couple of more items. But, when doing the job, \TEX\ is only interested in
+dimensions.
+
+In traditional \TEX\ an image inclusion happens via the extension primitive
+\type {\special}, so you can think of something:
+
+\starttyping
+\vbox to 10cm {%
+  \hbox to 4cm {%
+    \special{image foo.png width 4cm height 10cm}%
+    \hss
+  }%
+}
+\stoptyping
+
+When typesetting \TEX\ sees a box and uses its dimensions. It doesn't care what
+is inside. The special itself is just a so called whatsit that is not
+interpreted. When the page is eventually shipped out, the \DVI|-|to|-|whatever
+driver interprets the special's content and embeds the image.
+
+It will be clear that this will only work correctly when the image dimensions are
+communicated. That can happen in real dimensions, but using scale factors is also
+a variant. In the latter case one has to somehow determine the original dimensions
+in order to calculate the scale factor. When you embed \EPS\ images, which is the
+usual case in for instance \DVIPS, you can use \TEX\ macros to figure out the
+(high res) boundingbox, but for bitmaps that often meant that some external
+program had to do the analysis.
+
+It sounds complex but in practice this was all quite doable. I say \quote {was}
+because nowadays most \TEX\ users use an engine like \PDFTEX\ that doesn't need
+an external program for generating the final output format. As a consequence it
+has built-in support for analyzing and including images. There are additional
+primitives that analyze the image and additional ones that inject them.
+
+\starttyping
+\pdfximage
+  {foo.png}%
+\pdfrefximage
+  \pdflastximage
+  width 4cm
+  height 10cm
+\relax
+\stoptyping
+
+A difference with traditional \TEX\ is that one doesn't need to wrap them into a
+box. This is easier on the user (not that it matters much as often a macro
+package hides this) but complicates the engine because suddenly it has to check a
+so called extension whatsit node (representing the image) for dimensions.
+
+Therefore in \LUATEX\ this model has been replaced by one where an image
+internally is a special kind of rule, which in turn means that the code for
+checking the whatsit could go away as rules are already taken into account. The
+same is true for reuseable boxes (xforms in \PDF\ speak).
+
+\starttyping
+\useimageresource
+  {foo.png}%
+\saveimageresource
+  \lastsavedimageresourceindex
+  width 4cm
+  height 10cm
+\relax
+\stoptyping
+
+While \DVIPS\ supported \EPS\ images, \PDFTEX\ and \LUATEX\ natively support
+\PNG, \JPG\ en \PDF\ inclusion. The easiest to support is \JPG\ because the PDF\
+format supports so called \JPG\ compression in its full form. The engine only has
+to pass the image blob plus a bit of extra information. Analyzing the file for
+resolution, dimensions and colorspace is relative easy: consult some tables that
+have this info and store it. No special libraries are needed for this kind of
+graphics.
+
+A bit more work is needed for \PDF\ images. A \PDF\ file is a collection of
+(possibly compressed) objects. These objects can themselves refer to other
+objects so basically we we have a tree of objects. This means that when we embed
+a page from a \PDF\ file, we start with embedding the (content stream of the)
+page object and then embed all the objects it refers to, which is a recursive
+process because those objects themselves can refer to objects. In the process we
+keep track of which objects are copied so that when we include another page we
+don't copy duplicates.
+
+A dedicated library is used for opening the file, and looking for objects that
+tell us the dimensions and fetching objects that we need to embed. In \PDFTEX\
+the poppler library is used, but in \LUATEX\ we have switched to pplib which is
+specially made for this engine (by Pawel Jackowski) as a consequence of some
+interchange that we had at the 2018 Bacho\TEX\ meeting. This change of library
+gives us a greater independency and a much smaller code base. After all, we only
+need access to \PDF\ files and its objects.
+
+One can naively think that \PNG\ inclusion is as easy as \JPG\ inclusion because
+\PDF\ supports \PNG\ compression. Well, this is indeed true, but it only supports
+so called \PNG\ filter based compression. The image blob in a \PNG\ file
+describes pixels in rows and columns where each row has a filter byte telling how
+that row is to be interpreted. Pixel information can be derived from preceding
+pixels, pixels above it, or a combination. Also some averaging can come into
+play. This way repetitive information can (for instance) become for instance a
+sequence of zeros because no change in pixel values took place. And such a
+sequence can be compressed very well which is why the whole blob is compressed
+with zlib.
+
+In \PDF\ zlib compression can be applied to object streams so that bit is
+covered. In addition a stream can be \PNG\ compressed, which means that it can
+have filter bytes that need to be interpreted. But the \PNG\ can do more: the
+image blob is actual split in chunks that need to be assembled. The image
+information can be interlaced which means that the whole comes in 7~seperate
+chunks thet get overlayed in increasing accuracy. Then there can be an image mask
+part of the blob and that mask needs to be separated in \PDF\ (think of
+transparency). Pixels can refer to a palette (grayscale or color) and pixels can
+be codes in~1, 2, 4, 8 or 16~bits where color images can have 3~bytes. When
+multiple pixels are packed into one byte they need to be expanded.
+
+This all means that embedding \PNG\ file can demand a conversion and when you
+have to do that each run, it has a performance hit. Normally, in a print driven
+workflow, one will have straightforward \PNG\ images: 1 byte or 3 bytes which no
+mask and not interlaced. These can be transferred directly to the \PDF\ file. In
+all other cases it probably makes sense to convert the images beforehand (to
+simple \PNG\ or just \PDF).
+
+So, to summarize the above: a modern \TEX\ engine supports image inclusion
+natively but for \PNG\ images you might need to convert them beforehand if
+runtime matters and one has to run many times.

+Images are normally scaled proportionally but if needed you can give an
+explicit height and width. The \type {\scale} command shares this property
+and can be used to scale in the same way as \type {\externalfigure}. I will
+illustrate this with an example.
+
+You can define your own bitmaps, like I did with the cover of this manual:
+
+\typebuffer[image][option=LUA]
+

+
+\starttyping[option=TEX]

+  [width=\paperwidth]
+  {\getbuffer[image]}
+\stoptyping
+
+\stopsubject
+
+% \startsubject[title=The backend]
+%
+% Traditionally \TEX\ sees an image as just a box with dimensions and in \LUATEX\
+% it is actually a special kind of rule that carries information about what to
+% inject in the final (\PDF) file. In regular \LUATEX\ the core formats \type
+% {pdf}, \type {png}, \type {jpg} and \type {jp2} are dealt with by the backend but
+% in \CONTEXT\ we can use \LUA\ instead. We might default to that method at some
+% point but for now you need to enable that explicitly:
+%
+% \starttyping[option=TEX]
+% \enabledirectrive[graphics.pdf.uselua]
+% \enabledirectrive[graphics.jpg.uselua]
+% \enabledirectrive[graphics.jp2.uselua]
+% \enabledirectrive[graphics.png.uselua]
+% \stoptyping
+%
+% All four can be enabled with:
+%
+% \starttyping[option=TEX]
+% \enabledirectrive[graphics.uselua]
+% \stoptyping
+%
+% Performance|-|wise only \PNG\ inclusion can be less efficient, but only when you
+% use interlaced images or large images with masks. It makes no real sense in a
+% professional workflow to use the (larger) interlaced images, and masks are seldom
+% used at high resolutions, so in practice one will not really notice loss of
+% performance.
+%
+% The advantage of this method is that we can provide more options, intercept bad
+% images that make the backend abort and lessen the dependency on libraries.

+\startchapter[title=Actions]
+
+The reference mechanism not only deals with the more traditional cross
+references, but also takes care of navigation, launching applications (although
+that is often limited by viewers), running \JAVASCRIPT, etc. By integrating these
+features in one mechanism, we limit the number of commands needed for hyperlinks,
+menus and buttons. Normally such actions are driven by the \type {\goto} command,
+but you can also use buttons:
+
+\starttyping
+\goto[inner reference]
+\goto[outer reference::]
+\goto[outer reference::inner reference]
+\stoptyping
+
+The inner reference is normally a user defined one, for instance a reference to a
+named location like a chapter or figure. The outer reference refers to a file or
+\URL and is normally defined at the document level and is accessed by the \type
+{::}. By using symbolic names updating them becomes easier.
+
+There are also predefined references, like \type {nextpage} to go to the next
+page or \type {forward} to cycle, \type {nextcontents} for the next level table
+of contents in a linked list of such tables, etc. Some keywords are actually
+shortcuts to actions that are delegated to the viewer. Here you need to keep in
+mind that nowadays we're talking of \PDF\ viewers, but originally (\MKII) we also
+supported \DVI\ viewers. A special class of references are the viewer control
+ones, like \type {CloseDocument} or \type {PreviousJump}. They can be recognized
+by their capitals.
+
+When we speak of a reference, we actually refer to a whole bunch of possible
+references. We already mentioned inner and outer references, but special actions
+are also possible. These are actually plugins. Examples are the \JAVASCRIPT\ and
+\URL\ plugins. The interface evolved a bit over a few decades but most has been
+there right from the start, which is why we keep it as is. Actually, there is not
+that much new functionality added in \MKIV, although the implementation was
+mostly rewritten. Here is a overview of the syntax, just to give you an idea.
+
+\starttyping
+\goto[inner]
+\goto[inner(foo,bar)]
+\goto[inner{argument,argument}]
+\goto[inner{argument}]
+\goto[outer::]
+\goto[outer::inner]
+\goto[outer::special(operation{argument,argument})]
+\goto[outer::special(operation)]
+\goto[outer::special()]
+\goto[outer::inner{argument}]
+\goto[special(operation{argument})]
+\goto[special(operation{argument,argument})]
+\goto[special(operation)]
+\goto[special(outer::operation)]
+\goto[special(operation)]
+\goto[special(operation(whatever))]
+\goto[special(operation{argument,argument{whatever}})]
+\goto[special(operation{argument{whatever}})]
+\stoptyping
+
+There can be multiple actions, separated by a comma, think of: go to the page
+with label \quote {foo} and start video \quote {bar}.
+
+\showsetup{goto}
+
+Examples of operations are \type {page}, \type {program}, \type {action}, \type
+{url} and \type {JS}. \footnote {There are a few more operations but not all make
+sense at the user level.} The \type {page} operation accepts a pagenumber as
+well as relevant keywords. One can prefix a pagenumber by a file or \URL\ tag.
+The \type {program} operation starts up a program. It is an example of an old
+feature that has proven to be unstable, simply because viewers change behaviour
+over time.

+\startchapter[title=Annotations]
+
+Before we discuss interactive features (in following chapter) a few words will be
+spent on so called annotations. This term is used in Acrobat and is somewhat
+confusing as hyperlinks conceptually are not really annotations while comments
+are. The term relates to the way \PDF\ files can have added functionality. It
+might help understand the following chapters better when you know what model is
+used inside a \PDF.
+
+If you open a \PDF\ file in an editor you will finds lots of objects. Numbers are
+an object, as are strings and booleans. Symbols (represented as strings with a
+leading slash) are also objects. Objects can be collected in indexed tables
+(arrays) and hash tables (dictionaries). Serialized arrays are bounded by square
+brackets:
+
+\starttyping
+[ (value1) (value2) ]
+[ 1 2 3 ]
+[ 1 2 (value1) (value3) true /foo ]
+\stoptyping
+
+and hashes by double angle brackets:
+
+\starttyping
+<<
+    /Key1 (value1)
+    /Key2 (value2)
+    /Key3 123
+    /Key4 true
+    /Key5 [ 1 2 3 4 ]
+>>
+\stoptyping
+
+A \PDF\ file is a collection of objects:
+
+\starttyping
+1 0 obj
+    ...
+endobj
+\stoptyping
+
+Instead of a number, string, boolean, array or dictionary an object can also be
+a stream of bytes:
+
+\starttyping
+1 0 obj << /Length 123 >>
+stream
+... 123 bytes ...
+endstream
+endobj
+\stoptyping
+
+Objects can refer to each other and can be looked up via a so called xref table.
+We refer to object with number one and revision zero as follows:
+
+\starttyping
+/foo 1 0 R
+\stoptyping
+
+When an object is updated it can be added to the end of the file and the version
+number can get bumped. A program that does something with the \PDF\ is supposed
+to do something clever with these numbers. More often the revision stays zero.
+
+A document is normally a sequence of pages. When a file is opened the cross
+reference table is loaded and the so called catalog is looked up. From there
+pages can be found. Pages have a content stream and can refer to resources, like
+fonts, special color spaces, complex objects (xforms) and among other things
+annotations.
+
+The page is rendered from the content stream but that stream has no information
+about hyperlinks and such. The \type {/Link} annotation objects that implement
+interactivity are independent and kind of layered over the rendered page. They
+describe rectangular areas that a viewer can use to intercept mouse clicks. If
+you want to see where the actions happens, search for \type {/Dest} and \type
+{/Annot} in an (uncompressed) \PDF file. When you process a file with
+
+\starttyping
+\nopdfcompression
+\stoptyping
+
+you get an uncompressed file and with an appropriate editor you can see where
+annotations end up.
+
+The main reason for mentioning these details is that when you are checking a file
+for problems you need to look for annotation objects instead of the page stream.
+You also need to realize that these annotations in no way interfere with the page
+stream. They only exist because a viewer can use that information to add
+functionality. Their reference point is the lower left corner of the page. This
+is a conceptual difference with \HTML\ where hyperlinks are often in|-|line and
+part of the content stream. Both approaches have their advantages and
+disadvantages. From the perspective of quality typesetting it makes much sense to
+have them overlayed and explicitly defined (in terms of dimensions) but users
+will of course in most cases define them inline. This means that in order to make
+the \PDF\ some analyzing and juggling has to take place. In \CONTEXT\ we always
+have done as much as possible at the \TEX\ (therefore bypassing some limitations
+in the engine) end in \MKIV\ we don't use the engine's features at all.

+
+\startchapter[title=Attachments]
+
+Attachments are (normally) embedded files that the reader can extract. A viewer
+can decide to just show the content or call an associated program to deal with
+the file (which one depends on the operating system). As with other annotations
+they started out depicted by symbols but then browsers started showing them in
+lists next to the displayed page.
+
+\startbuffer
+\attachment
+  [attachment 1]
+  [file=interaction-attached-001.txt,
+   title=Just some text,
+   width=2em,
+   height=2em,
+   author=Hans,
+   subtitle=Plain text]
+
+\attachment
+  [attachment 2]
+  [file=cow.mp,
+   title=Just a graphic,
+   author=Hans,
+   subtitle=Some MetaPost,
+   method=hidden]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+These two attachments differ in one aspect: the second one is hidden, i.e. it has
+no icon in the text. However, the attachment is in the file and is (often)
+visible in the side bar. The symbol for the visible one is in the margin, which
+is achieved with:
+
+\starttyping
+\setupattachment
+  [location=inmargin]
+\stoptyping
+
+You can use your own icon, for instance:
+
+\startbuffer
+\startuniqueMPgraphic{cow}{height,s:color}
+    loadfigure "cow.mp" number 1 ;
+    refill currentpicture withcolor "\MPvar{color}"    ;
+    currentpicture := currentpicture ysized \MPvar{height} ;
+\stopuniqueMPgraphic
+
+\definesymbol
+  [attachment-normal]
+  [\uniqueMPgraphic{cow}{height=4ex,color=darkblue}]
+\definesymbol
+  [attachment-down]
+  [\uniqueMPgraphic{cow}{height=4ex,color=darkyellow}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+% \startattachment[hello][symbol={attachment-normal,attachment-down}]
+%     oeps
+% \stopattachment
+
+\attachment
+  [symbol={attachment-normal,attachment-down},
+   file=cow.pdf,
+   title=A cow,
+   author=Hans,
+   subtitle=graphic]
+
+This time we get a cow as icon and the cow is also embedded as image. When
+writing this manual a click in Sumatra just opens the \PDF\ file, but when I
+embed an mp3 file, a save-as window pops up.
+
+The previous examples directly injected the attachment using the \type
+{\attachment} commands with the appropriate arguments. You can add titles, define
+a name that will be used when the attachment is saved:
+
+\starttyping
+\attachment[sometag][extra specs]
+\attachment[test.tex]
+\attachment[file=test.tex]
+\attachment[file=test.tex,method=hidden]
+\attachment[name=newname,file=test.tex]
+\attachment[title=mytitle,name=newname,file=test.tex]
+\stoptyping
+
+but there's also a more indirect way, for instance here we define some
+attachments:
+
+\starttyping
+\defineattachment[whatever-1][file=test.tex]
+\defineattachment[whatever-2][file=test.tex,method=hidden]
+\stoptyping
+
+that later can be called up with:
+
+\starttyping
+\attachment[whatever-1][method=hidden]
+\attachment[whatever-2]
+\stoptyping
+
+where of course hidden is to be omitted when you want an icon. The commands that
+are used to define and tune an instance are:
+
+\showsetup{defineattachment}
+
+\showsetup{setupattachment}
+
+There is one predefined instance:
+
+\starttyping
+\defineattachment[attachment]
+\stoptyping
+
+So we have:
+
+\showsetup{startattachment:instance}
+
+\showsetup{attachment:instance}
+
+Yet another level of abstraction can be achieved with:
+
+\showsetup{registerattachment}
+
+For example:
+
+\starttyping
+\registerattachment
+  [sometag]
+  [name=fool.txt,
+   file=foo.txt,
+   title=Fool me,
+   subtitle=Not you,
+   author= Joker]
+\stoptyping
+
+This is the \MKIV\ replacement for the \MKII\ method:
+
+\starttyping
+\useattachment[test.tex]
+\useattachment[whatever][test.tex]
+\useattachment[whatever][newname][test.tex]
+\useattachment[whatever][title][newname][test.tex]
+\stoptyping
+
+or with all options:
+
+\starttyping
+\useattachment[name][file][author][title][subtitle]
+\stoptyping
+
+The \type {\use...} variant stays around for old times sake and just maps onto
+\type {\registerattachment}, you can better use that one because it frees you
+from remembering which arguments is what for.

+There is not much to tell about buttons. They are clickable areas on the screen

+Buttons are an example of a construct that builds upon \type {\framed} so the
+keys that apply there also apply to buttons. You can enable or disable buttons
+with the \type {state} parameter. As usual there are a \type {style} and \type
+{color} parameters and an additional \type {contrastcolor} option for tuning the
+color of a button which action let you stay on the same page. Actually, when you
+do stay on the same page, the \type {samepage} parameter let you control if the
+button should be empty, hidden or whatever.

+\startchapter[title={Comments}]
+
+Many \PDF\ viewers support text annotations. These are small notes that can be
+popped up. In \CONTEXT\ we call them comments, because often that's what they are
+used for. Comments evolved from simple ones using a limited encoding into more
+advanced ones with representations. A comment looks like:
+
+\startbuffer
+\startcomment
+  Hello beautiful world!
+\stopcomment
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+When you open a document with comment you will likely see some symbol depicting
+it. But, it's one of those features that is viewer dependent so when it looks odd
+or unexpected, check in \ACROBAT\ first. The position and size can differ per
+viewer and when you zoom in the size can either stay the same or scale. The
+viewer can show the pop up text at the same location or someplace else. Although
+in principle there is control over this, my experience is that viewers (also
+Acrobat) keep changing this (not always for the best). Just assume the worst: it
+will never look good and although for a while we kept up with viewers, the
+inconsistency (and accumulated waste of time) led us to the current minimalistic
+approach.
+
+By default, in \CONTEXT\ comments are placed at the spot a bit raised. In this
+document we put them in the margin, by saying:
+
+\starttyping
+\setupcomment
+  [location=inmargin]
+\stoptyping
+
+Comments can have titles and properties but not all viewers support properties.
+Contrary to other environments, the first argument is not a category but a title.
+This because we are compatible with \MKII.
+
+\startbuffer
+\startcomment[french]
+  In France they use «angle bracket glyphs» in subsentences.
+\stopcomment
+
+\startcomment[accents][color=darkgreen]
+  You can used an àçéñţêð character too.
+\stopcomment
+\stopbuffer
+
+\typebuffer \getbuffer
+
+And normally empty lines are also supported (again this can differ per viewer):
+
+\startbuffer
+\startcomment[lines][color=darkblue]
+  How about an
+
+  empty line?
+\stopcomment
+\stopbuffer
+
+\typebuffer \getbuffer
+
+As we can see here, comments are sort of stacked. These examples also show that
+we can pass an optional title and set up some characteristics. An inline comment
+is defined with \type {\comment}:
+
+\startbuffer
+\comment {How I hate those notes spoiling the layout.} Maybe some day
+I can convince myself to add some features \comment {Think of comment classes
+that can be turned on and off and get their own colors.} related to version
+control.
+\stopbuffer
+
+\typebuffer
+
+\inlinebuffer\ Comments hide part of the text and thereby are to be used with
+care. Until now I never used them. Anyhow, from now on, one can happily use:
+
+You can use other symbols than the default, and a couple are predefined in
+the standard: {\tt \cldcontext {table.concat (lpdf.commentsymbols(), ", ")}}.
+
+\startbuffer
+\startcomment[symbol=Help]
+  Do we want this kind of rubish?
+\stopcomment
+\stopbuffer
+
+You can also use your own symbols:

+% \definesymbol [comment-down]  [{\externalfigure[cow.pdf]}]
+%
+% \unexpanded\def\CowSymbol#1#2%

+

+
+\startbuffer
+\startcomment[hello][symbol={comment-normal,comment-down}]
+    oeps
+\stopcomment
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Again the way this shows up depends on the viewer capabilities so there might be
+a fallback on the normal comment symbol. You can influence the size of the image
+(icon):
+
+\startbuffer
+\startcomment[hello]
+    [symbol={comment-normal,comment-down},width=\marginwidth]
+    oeps
+\stopcomment
+\stopbuffer
+
+\typebuffer \getbuffer
+
+There are some options that you can use for finetuning the comments.
+
+\showsetup{setupcomment}
+
+A new instance is defined with:
+
+\showsetup{definecomment}
+
+The default instance is predefined by

+Interaction is turned off by default. Of course cross referencing
+work without interaction but there are no hyperlinks. You turn on
+interaction with the \type {\setupinteraction} command:
+
+\showsetup {setupinteraction}
+
+The \type {state} key is the switch you need to use. In addition you might want
+to setup the style and color.
+
+\starttyping
+\setupinteraction
+  [state=start,
+   style=,
+   color=,
+   contrastcolor=]
+\stoptyping
+
+This is the least intrusive way to get interaction in your document. By default
+the style is bold and the \type {color} defaults to green. The \type
+{contrastcolor} is used when a hyperlink refers to the same page and defaults to
+red. A neutral setup makes sense because nowadays the reader kind of knows what
+can be clicked on.
+
+The \type {title}, \type {subtitle}, \type {author}, \type {date} and \type
+{keyword} parameters are passed to the document and will show up when you request
+document information.
+
+The \type {openaction} parameter can for instance be used to start at a specific
+page, while the \type {closeaction} can be used to trigger a \JAVASCRIPT\ cleanup
+script. The \type {openpageaction} and \type {closepageaction} can for instance
+initialize and reset states, something we do in some presentation styles.
+
+The \type {click} parameter controls how a viewer responds to pressing a mouse
+button on an annotation: highlight or not. The \type {display} parameter
+determines if a cross document link opens in the current window.
+
+The \type {menu} parameter is a quick way to disable menus, of which there can be
+many: at each side of the page, stacked or not, etc. The \type {symbolset}
+determines the look and feel of symbols used in for instance menus, buttons and
+status bars.
+
+The \type {page} parameters is a bit special, and it function is an inheritance
+from the early days. Some \DVI\ and \PDF\ viewers supported named destinations,
+others only page references. This parameter can be used to force one or the
+other. There was a time that there was a limit on the number of named references,
+so going page was the only option \footnote {We're talking of 1995 when we made
+documents of many thousands of pages with tens of thousands of hyperlinks, cross
+linked tables of contents, registers, active graphics, etc.\ Think of
+dictionaries used in very specific projects, or quality assurance manuals.}
+
+Personally I consider an electronic document an entity to be seen full screen on
+a dedicated device. However some users prefer the target of a link to fit the
+width of the screen and alike. The \type {focus} parameter can (within)
+reasonable bounds provide this. The \type {focusoffset} is then used to keep
+things a bit visual convenient.
+
+The \type {height} and \type{depth} parameters are sort of special and probably never
+used. When we go back in time, to when we started adding interactivity, there were
+a few issues that needed to be dealt with:
+
+\startitemize[packed]
+\startitem
+    We need to make sure that we have something to click on, so we need to add
+    some offset if needed.
+\stopitem
+\startitem
+    We need to handle nested hyperlinks, which is why \CONTEXT\ didn't use the
+    link features of for instance \PDFTEX\ but built its own.
+\stopitem
+\startitem
+    Hyperlinks should break properly across lines without side effects, again a
+    reason for bypassing some of the \TEX\ engine's behaviour.
+\stopitem
+\startitem
+    We have to make sure that there is at least a consistent height and depth
+    of hyperlinks. These tight links with viewer supplied bounding boxes to
+    click on just look real bad! So, we had to do better.
+\stopitem
+\stopitemize
+
+Normally the two mentioned parameters are not used. However, their value will
+kick in when we say \type {\setfalse \locationstrut}, in which case the given
+height and depth will be used. Some advice: don't mess with this. We only have
+this because it permits special effects.
+
+If you want to see what the target (destinations) and sources (references) of
+links are, you can say:
+
+\starttyping
+\enabletrackers[nodes.references,nodes.destinations]
+\stoptyping
+
+The \type {fieldlayer} parameter can be used to set a so called viewer layer, so
+that you can hide them (given that a viewer supports that). The \type {calculate}
+parameter can associate a calculator (initializer) with the fields.
+
+You can create an interaction environment with:
+
+\showsetup {defineinteraction}
+
+which then can be used with:
+
+\showsetup {startinteraction}

+A hyperlink is something that you click on and that brings you to nother spot in

+\startchapter[title=Importing]
+
+This is a very short chapter that deals with external figures. Normally an image
+is a graphic with possible some text. There are however workflows where one
+includes pages from other documents. Such documents can contain cross references,
+bookmarks, comments and|/|or fields. Normally annotations of any kind are ignored
+and for good reason: they assume the whole document to be the, not just one or a
+few pages. Merging references for instance is a source for clashes, not only for
+named ones but also for page references.
+
+But when you {\em know} what you're doing, as for instance Taco (who requested
+this feature) does, there is a way to merge annotations. This is controlled by
+the interaction keys in \type {externalfigure}:
+
+\starttyping
+\externalfigure[somedoc][page=1,interaction=yes]
+\externalfigure[somedoc][page=2,interaction={reference,bookmark}]
+\stoptyping
+
+However, only references and bookmarks are officially supported! The other
+annotations are possible but the code is experimental and will be finished
+when we find a good reason for it.
+
+\starttabulate[|B|p|]
+\FL
+\NC \type {reference} \NC named and page references and urls \NC \NR
+\NC \type {comment}   \NC comments if possible with relevant icon \NC \NR
+\NC \type {bookmark}  \NC text bookmarks that refer to pages \NC \NR
+\NC \type {field}     \NC widgets but only within reason \NC \NR
+\NC \type {layer}     \NC viewer layers \NC \NR
+\ML
+\NC \type {yes}       \NC named and page references, urls and bookmarks \NC \NR
+\NC \type {all}       \NC all annotations \NC \NR
+\LL
+\stoptabulate
+
+If things don't work out well, imagine for a while what is involved in supporting
+this: analyzing a page from a document, remapping the annotations onto some
+\CONTEXT\ mechanism, making sure that we don't get clashes, keeping overhead
+acceptable.
+
+Because this is a somewhat tricky feature, tracing can help you to identify
+problems: \typ {figures.merging}, \typ {figures.links}, \typ {figures.comments},
+\typ {figures.fields} and \typ {figures.outlines}.
+
+Another complication when including pages can be the presence of so called marked
+content in the page stream. There is experimental support for removing those but
+right now (2018) you need to explicitly enable this explicitly:
+
+\starttyping
+\enabledirectives[graphics.pdf.uselua]
+\enabledirectives[graphics.pdf.stripmarked]
+%enabledirectives[graphics.pdf.recompress]
+\stoptyping
+
+This will delegate inclusion from the backend to \LUA. This might become the
+default as it is just as efficient as using the backend. That way we can filter
+the content stream. \footnote {We might add a callback to \LUATEX\ for filtering
+the content stream (no hard todo but post version 1.10).}

+\startchapter[title=Introduction]
+
+This document introduces the cross reference mechanism, viewer control, fill||in
+fields, \JAVASCRIPT\ support, comments, attachments and more. It is a rewrite of
+the \MKII\ widgets manual. There is (always) more available than discussed in
+manuals so if you miss something, take a look at test suite or when you're brave,
+peek into the source code as there can be examples there.
+
+Interactivity has always been available in \CONTEXT\ and in fact it was one of
+the reasons for writing it. In for instance the YandY \WINDOWS\ previewer, one
+could have hyperlinks and we used that for a while when checking documents. Later
+Acrobat showed up and \PDF\ stepwise added interactive features that we always
+supported right from the start. Unfortunately there is a viewer dependency and
+the documentation of \PDF\ lagged behind, so solutions based on trial and error
+could not work well in a follow up on \PDF. Some features disappeared or became
+so limited that they effectively became useless. Especially multi||media have a
+reputation of unreliability. Because open source viewers never really catched up
+(at least not in this area) the momentum was lost to make sure that documents
+could have audio and video embedded in reliable ways. Even forms and basic
+\JAVASCRIPT\ control of for instance layers is often missing.
+
+That said, we do support a lot but can support more when it makes sense. Deep
+down in \CONTEXT\ we always had the mechanisms to deal with this, so extensions
+are not that hard to program. Somehow we thought that publishers would like these
+features but that never really was the case, so there was no pressure from that
+end. Most features are user driven or just there because at some point we wanted
+to make some fancy presentation. In fact, the \type {s-present-*} files provide
+examples of interactivity.
+
+The original \PDF\ reference was a couple of hundred pages and looked quite nice.
+A later print has many more pages and still looks ok, but nowadays we have to do
+with a \PDF\ document. If you want to see what \PDF\ supports you can study this
+(now about) 750 page standard. It is, being an \ISO\ standard, not public but
+you can probably find a (maybe older) copy someplace on the web.
+
+When reading this manual you need to keep in mind that we assume that you design
+a decent layout and when you make something for an electronic medium, we hope
+that you pay attention to the way you can enhance accessibility.
+
+If you miss something here, don't hesitate to ask for clarification, or even
+better, provide an example that we then can use to discuss (an aspect of) some
+mechanism.

+
+Annotations can be controlled with \JAVASCRIPT\ but it really depends on the
+viewer if it works out well. Using these scripts is a multi||step process where
+common functions and data structures can be shared and collected in preambles:
+
+\starttyping
+\startJSpreamble {name}
+  MyCounter = 0 ;
+\stopJSpreamble
+\stoptyping
+
+The more action oriented scripts are defined as:
+
+\starttyping
+\startJScode {increment}
+  MyCounter = MyCounter + 1 ; // or: ++MyCounter ;
+\stopJScode
+\stoptyping
+
+This script is executed with:
+
+\starttyping
+\goto {advance by one} [JS(increment)]
+\stoptyping
+
+Nicer is to define a function:
+
+\starttyping
+\startJSpreamble {helpers} used now
+    function Increment(n) {
+        MyCounter = MyCounter + n ;
+    }
+\stopJSpreamble
+\stoptyping
+
+and then say:
+
+\starttyping
+\goto {advance by one} [JS(Increment{5})]
+\stoptyping
+
+The distribution contains a collection of scripts that can be preloaded and used
+when needed. You can recognize the files by the \type {java-imp-} prefix. To
+prevent all preambles ending up in the \PDF\ file, we can say:
+
+\starttyping
+\startJSpreamble {something} used later
+\stopJSpreamble
+\stoptyping
+
+We already saw that one can also say \type {used now} and there's also a way
+to filter specific preambles on usage:
+
+\starttyping
+\startJScode {mything} uses {something}
+\stopJScode
+\stoptyping
+
+One should be aware of the fact that there is no decent way to check if every
+script is all right! Even worse, the \JAVASCRIPT\ interpreter currently used in
+the \ACROBAT\ tools is not reentrant, and breaks down on typos
+
+The full repertoire of commands is:
+
+\showsetup{startJScode}
+
+\showsetup{startJSpreamble}
+
+\showsetup{addtoJSpreamble}
+
+\showsetup{setJSpreamble}
+
+As we're into \LUA\ and because \LUA\ is so lightweight I've wondered several
+times now if it would make sense to embed \LUA\ in \PDF\ viewers. After all,
+annotations are an extension mechanism. In the early days of \PDF\ this was
+actually quite doable because \ACROBAT\ reader (and exchange) had a plugin model.
+However, the more functionality ended up in the program, the least interesting
+(and popular) the plugins mechanism became. Some open source viewers have an
+\API\ so in principle adding the lightweight \LUA\ interpreter (of course with
+\LPEG, and quite probably without file \IO) is possible. It has been discussed at
+a recent \CONTEXT\ meeting, so who knows \unknown For now we're stuck with
+\JAVASCRIPT.
+
+An example of \JAVASCRIPT\ usage is the following, where we load a video and add
+some controls. Beware that this kind of functionality is very viewer dependent
+and therefore also very unstable over time. Even worse, if you look at the loaded
+\JAVASCRIPT\ file you will notice a dependency on soon obsolete (in \ACROBAT\ at
+least) shockwave support. First we load a library that will predefine a video
+graphic: and then create an instance:
+
+\starttyping
+\useJSscripts[vplayer]
+
+\setupinteraction
+  [state=start]
+
+\externalfigure
+  [shockwave]
+  [frame=on,
+   width=480pt,
+   height=270pt,
+   file=test.mp4,
+   label=foo]
+\stoptyping
+
+The controls are defined with:
+
+\starttyping
+\goto{START} [JS(StartShockwave{foo})]
+\goto{REWIND}[JS(RewindShockwave{foo})]
+\goto{PAUSE} [JS(PauseShockwave{foo})]
+\goto{STOP}  [JS(StopShockwave{foo})]
+\stoptyping
+
+or, as we have some defined reference shortcuts:
+
+\starttyping
+\goto{START} [StartShockwave{foo}]
+\goto{REWIND}[RewindShockwave{foo}]
+\goto{PAUSE} [PauseShockwave{foo}]
+\goto{STOP}  [StopShockwave{foo}]
+\stoptyping
+
+It's actually not that hard to add all kind of functionality if only we could be
+sure of stable support and continuity.

+
+I'm not sure if this feature is still used but in the early days of \PDF\ support
+in \TEX, users loved it. I never really used it myself. Page transitions only
+make sense in presentations, and unfortunately the ones provided by the Acrobat
+viewers are just ugly. Anyhow, one automatically gets them by saying:
+
+\starttyping
+\setuppagetransitions[random]
+\stoptyping
+
+This way one gets random transitions. Resetting transitions is done by:
+
+\starttyping
+\setuppagetransitions[reset]
+\stoptyping
+
+If needed one can specify transitions but I strongly advice against this, because
+these commands are very viewer dependant, therefore: if in despair, use numbers!
+By default, the next set is used, and one can access them by number,

+
+\section{Fill||in fields}
+
+Fields come in many disguises. Currently \CONTEXT\ supports
+the field types provided by \PDF, which in turn are derived
+from \HTML. Being a static format and not a programming
+language, \PDF\ only provides the interface. Entering data
+is up to the viewer and validation to the built in
+\JAVASCRIPT\ interpreter. The next paragraph shows an
+application.
+
+\startbuffer
+A few years back, \TEX\ could only produce \fillinfield [dvi]
+{\DVI} output, but nowadays, thanks to \fillinfield {Han The
+Thanh}, we can also directly produce \fillinfield [pdf] {\PDF}!
+Nice eh? Actually, while the first field module was prototyped
+in \ACROBAT, the current implementation was debugged in
+\fillinfield [pdfTeX] {\PDFTEX}. Field support in \fillinfield
+[ConTeXt] {\CONTEXT} is rather advanced and complete and all
+kind of fields are supported. One can hook in appearances, and
+validation \fillinfield [JavaScripts] {\JAVASCRIPT}'s. Fields
+can be cloned and copied, where the latter saves some space. By
+using \fillinfield {objects} when suited, this module saves
+space anyway.
+\stopbuffer
+
+\getbuffer
+
+This paragraph is entered in the source file as:
+
+\typebuffer
+
+I leave it to the imagination of the user how
+\type{\fillinfield} is implemented, but trust me, the
+definition is rather simple and is based on the macros
+mentioned below.
+
+Because I envision documents with many thousands of fields,
+think for instance of tutorials, I rather early decided to
+split the definition from the setup. Due to the fact that
+while typesetting a field upto three independant instances
+of \type{\framed} are called, we would end up with about
+150~hash entries per field, while in the current
+implementation we only need a few. Each field can inherit
+its specific settings from the setup group it belongs to.
+
+Let's start with an example of a {\em radio} field. In fact
+this is a collection of fields. Such a field is defined
+with:
+
+\startbuffer
+\definefield
+  [Logos] [radio] [LogoSetup]
+  [ConTeXt,PPCHTEX,TeXUtil] [PPCHTEX]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+Here the fourth argument specifies the subfields and the
+last argument tells which one to use as default. We have to
+define the subfields separately:
+
+\startbuffer
+\definesubfield [ConTeXt] [] [ConTeXtLogo]
+\definesubfield [PPCHTEX] [] [PPCHTEXLogo]
+\definesubfield [TeXUtil] [] [TeXUtilLogo]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+The second argument specifies the setup. In this example
+the setup (\type {LogoSetup}) is inherited from the main
+field. The third arguments tells \CONTEXT\ how the fields
+look like when turned on. These appearances are to be
+defined as symbols:
+
+\startbuffer
+\definesymbol [ConTeXtLogo] [{\externalfigure[mp-cont.502]}]
+\definesymbol [PPCHTEXLogo] [{\externalfigure[mp-cont.503]}]
+\definesymbol [TeXUtilLogo] [{\externalfigure[mp-cont.504]}]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+Before we typeset the fields, we specify some settings to use:
+
+\startbuffer
+\setupfield [LogoSetup]
+  [width=4cm,
+   height=4cm,
+   frame=off,
+   background=screen]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+Finally we can typeset the fields:
+
+\startbuffer
+\hbox to \hsize
+  {\hss\field[ConTeXt]\hss\field[PPCHTEX]\hss\field[TeXUtil]\hss}
+\stopbuffer
+
+\typebuffer
+
+This shows up as:
+
+\startbaselinecorrection
+\getbuffer
+\stopbaselinecorrection
+
+An important characteristic of field is cloning cq.\
+copying, as demonstrated below:
+
+% \tracefieldstrue
+
+\startbuffer[symbol]
+\definesymbol [yes-a] [$\times$]
+\definesymbol [yes-b] [$\star$]
+\definesymbol [nop-a] [$\bullet$]

+

+\clonefield [ex-b] [ex-q] [setup 2] [yes-b,nop-b]
+\clonefield [ex-c] [ex-r] [setup 2] [yes-b,nop-b]
+\stopbuffer
+
+\getbuffer[clone]
+
+\startbuffer[copy]
+\copyfield [ex-a] [ex-x]
+\copyfield [ex-b] [ex-y]
+\copyfield [ex-c] [ex-z]
+\stopbuffer
+
+\getbuffer[copy]
+
+\startbuffer[setup]
+\setupfield [setup 1] [width=1cm,height=1cm,framecolor=red]
+\setupfield [setup 2] [width=.75cm,height=.75cm]
+\stopbuffer
+
+\getbuffer[setup]
+
+\startbuffer[field]
+\hbox to \hsize
+  {\field[ex-a]\hfil\field[ex-b]\hfil\field[ex-c]\hfil\hfil
+   \field[ex-p]\hfil\field[ex-q]\hfil\field[ex-r]\hfil\hfil
+   \field[ex-x]\hfil\field[ex-y]\hfil\field[ex-z]}
+\stopbuffer
+
+\startbaselinecorrection \getbuffer[field] \stopbaselinecorrection
+
+The next table shows the relations between these fields of type radio:
+
+\startbaselinecorrection
+\showfields
+\stopbaselinecorrection
+
+This table is generated by \type {\showfields} and can be
+used to check the relations between fields, but only when
+we have set \type {\tracefieldstrue}. Radio fields have the
+most complicated relationships of fields, due to the fact
+that only one of them can be activated (on). By saying
+\type {\logfields} one can write the current field
+descriptions to the file \type {fields.log}.
+
+Here we used some \TEX\ mathematical symbols. These are
+functional but sort of dull, so later we will define a more
+suitable visualization.
+
+\typebuffer[symbol]
+
+The parent fields were defined by:
+
+\typebuffer[define]
+
+and the clones, which can have their own appearance, by:
+
+\typebuffer[clone]
+
+The copies are defined using:
+
+\typebuffer[copy]
+
+using the setups
+
+\typebuffer[setup]
+
+Finally all these fields are called using \type {\field}:
+
+\typebuffer[field]
+
+Now we will define a so called {\em check} field. This
+field looks like a radio field but is independant of
+others. First we define some suitable symbols:
+
+\startbuffer
+\definesymbol [yes] [{\externalfigure[mp-cont.502]}]
+\definesymbol [no]  []
+\stopbuffer
+
+\getbuffer
+
+\typebuffer
+
+A check field is defined as:
+
+\startbuffer
+\definefield [check-me] [check] [setup 3] [yes,no] [no]
+\stopbuffer
+
+\getbuffer
+
+\typebuffer
+
+This time we say \type{\field[check-me]} and get:
+
+\startbuffer
+\setupfield
+  [setup 3]
+  [width=2cm, height=2cm,
+   rulethickness=3pt, corner=round, framecolor=red]
+\stopbuffer
+
+\getbuffer
+
+\startlinecorrection
+\hbox to \hsize{\hss\field[check-me]\hss}
+\stoplinecorrection
+
+As setup we used:
+
+\typebuffer
+
+We already saw an example of a {\em line} field. By default
+such a line field looks like:
+
+\startbuffer[define]
+\definefield [Email] [line] [ShortLine] [] [pragma@wxs.nl]
+\stopbuffer
+
+\getbuffer[define]
+
+\startbuffer[field]
+\field [Email] [your email]
+\stopbuffer
+
+\startbaselinecorrection \getbuffer[field] \stopbaselinecorrection
+
+We defined this field as:
+
+\typebuffer[define]
+
+and called it using a second, optional, argument:
+
+\typebuffer[field]
+
+As shown, we can influence the way such a field is typeset.
+It makes for instance sense to use a monospaced typeface
+and limit the height. When we set up a field, apart from
+the setup class we pass some general characteristics, and
+three more detailed definitions, concerning the
+surrounding, the label and the field itself.
+
+\startbuffer
+\setupfield
+  [ShortLine]
+  [label,frame,horizontal]
+  [offset=4pt,height=fit,framecolor=green,
+   background=screen,backgroundscreen=.80]
+  [height=18pt,width=80pt,align=middle,
+   background=screen,backgroundscreen=.90,frame=off]
+  [height=18pt,width=80pt,color=red,align=right,style=type,
+   background=screen,backgroundscreen=.90,frame=off]
+\stopbuffer
+
+\typebuffer
+
+So now we get:
+
+\getbuffer
+
+\startbuffer[mainmail]
+\definemainfield [MainMail] [line] [ShortLine] [] [pragma@wxs.nl]
+\stopbuffer
+
+\getbuffer[mainmail]
+
+\startlinecorrection
+\field [MainMail] [your email]
+\stoplinecorrection
+
+Such rather long definitions can be more sparse when we set
+up all fields at once, like:
+
+\startbuffer
+\setupfields
+  [label,frame,horizontal]
+  [offset=4pt,height=fit,framecolor=green,
+   background=screen,backgroundscreen=.80]
+  [height=18pt,width=80pt,
+   background=screen,backgroundscreen=.90,frame=off]
+  [height=18pt,width=80pt,color=red,align=middle,
+   background=screen,backgroundscreen=.90,frame=off]
+\stopbuffer
+
+\typebuffer
+
+So given that we have defined field \type {MainMail} we can
+say:
+
+\startbuffer[MP]
+\startuniqueMPgraphic{button}
+  path p ; p := fullcircle xyscaled (OverlayWidth,OverlayHeight) ;
+  fill p withcolor (.8,.8,.8) ;
+  draw p withcolor OverlayColor withpen pencircle scaled 3 ;
+\stopuniqueMPgraphic
+
+\defineoverlay [normalbutton] [\uniqueMPgraphic{button}]
+\stopbuffer
+
+\getbuffer[MP]
+
+\startbuffer
+\setupfield [LeftLine]
+  [background=normalbutton, backgroundcolor=darkgreen,
+   offset=2ex, height=7ex, width=.25\hsize,
+   style=type, frame=off, align=left]
+\setupfield [MiddleLine]
+  [background=normalbutton, backgroundcolor=darkgreen,
+   offset=2ex, height=7ex, width=.25\hsize,
+   style=type, frame=off, align=middle]
+\setupfield [RightLine]
+  [background=normalbutton, backgroundcolor=darkgreen,
+   offset=2ex, height=7ex, width=.25\hsize,
+   style=type, frame=off, align=right]
+
+\clonefield [MainMail] [LeftMail]   [LeftLine]
+\clonefield [MainMail] [MiddleMail] [MiddleLine]
+\clonefield [MainMail] [RightMail]  [RightLine]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+We get get three connected fields:
+
+\startlinecorrection
+\hbox to \hsize
+  {\field[LeftMail]\hss\field[MiddleMail]\hss\field[RightMail]}
+\stoplinecorrection
+
+(Keep in mind that in \CONTEXT\ left aligned comes down to
+using \type {\raggedleft}, which can be confusing, but
+history cannot be replayed.)
+
+By the way, this shape was generated by \METAPOST\ using
+the overlay mechanism:
+
+\typebuffer[MP]
+
+Due to the fact that a field can have several modes (loner,
+parent, clone or copy), one cannot define a clone or copy
+when the parent field is already typeset. When one knows in
+advance that there will be clones or copies, one should
+use:
+
+\typebuffer[mainmail]
+
+Now we can define copies, clones and even fields with the
+same name, also when the original already is typeset. Use
+\type {\showfields} to check the status of fields. When in
+this table the mode is typeset slanted, the field is not
+yet typeset.
+
+The values set up with \type {\setupfield} are inherited by
+all following setup commands. One can reset these default
+values by:
+
+\startbuffer
+\setupfields[reset]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+When we want more than one line, we use a {\em text} field.
+Like the previous fields, text must be entered in the
+viewer specific encoding, in our case, \PDF\ document
+encoding. To free users from thinking of encoding,
+\CONTEXT\ provides a way to force at least the accented
+glyphs into a text field in a for \TEX\ users familiar way:
+
+\setupfields
+  [horizontal]
+  [offset=4pt,height=fit,framecolor=green,
+   background=screen,backgroundscreen=.80]
+  [height=18pt,width=80pt,
+   background=screen,backgroundscreen=.90,frame=off]
+  [height=18pt,width=80pt,color=red,align=middle,
+   background=screen,backgroundscreen=.90,frame=off]
+
+\definefield
+  [SomeField] [text] [TextSetup]
+  [hi there, try \string\\ \string " e or
+   \string\\ \string~ n to get \"e or \~n]
+
+\setupfield
+  [TextSetup]
+  [label,frame,horizontal][framecolor=green][]
+  [height=80pt,width=240pt,style=\sl,align=middle,
+   enterregion=JS(Initialize_TeX_Key),
+   afterkey=JS(Convert_TeX_Key),
+   validate=JS(Convert_TeX_String)]
+
+\startbaselinecorrection
+\field[SomeField][Just Some Text]
+\stopbaselinecorrection
+
+Now, how is this done? Defining the field is not that hard:
+
+\starttyping
+\definefield [SomeField] [text] [TextSetup] [default text]
+\stoptyping
+
+The conversion is taken care of by a \JAVASCRIPT's. We can assign such
+scripts to mouse and keyboard events, like in:
+
+\starttyping
+\setupfield
+  [TextSetup][...][...][...]
+  [....,
+   regionin=JS(Initialize_TeX_Key),
+   afterkey=JS(Convert_TeX_Key),
+   validate=JS(Convert_TeX_String)]
+\stoptyping
+
+The main reason for using the \type{JS(...)} method here is
+that this permits future extensions and looks familiar at
+the same time. Depending on the assignments, one can
+convert after each keypress and|/|or after all text is
+entered.
+
+\startbuffer
+\definefield
+  [Ugly] [choice] [UglySetup]
+  [ugly,awful,bad] [ugly]
+\setupfield
+  [UglySetup]
+  [width=6em,
+   height=1.2\lineheight,
+   location=low]
+\stopbuffer
+
+\getbuffer
+
+We've arrived at another class of fields: {\em choice},
+{\em pop||up} and {\em combo} fields. All those are menu
+based (and \vbox{\field[Ugly]}). This in||line menu was
+defined as:
+
+\typebuffer
+
+\startbuffer
+\definefield
+  [Ugly2] [popup] [UglySetup]
+  [ugly,awful,bad] [ugly]
+\definefield
+  [Ugly3] [combo] [UglySetup]
+  [ugly,{AWFUL=>awful},bad] [ugly]
+\stopbuffer
+
+\getbuffer
+
+Pop||up fields look like: \vbox{\field[Ugly2]} and combo
+fields permit the user to enter his or her own option:
+\vbox{\field[Ugly3]}. The amount of typographic control
+over these three type of fields is minimal, but one can
+specify what string to show and what string results:
+
+\typebuffer
+
+Here \type{AWFUL} is shown and when selected becomes the
+choice \type{awful}. Just in case one wonders why we use
+\type{=>}, well, it just looks better and the direction
+shows what value will be output.
+
+\startbuffer[uglies]
+\definefieldset [AllUglies] [Ugly, Ugly2, Ugly3]
+\stopbuffer
+
+\getbuffer[uglies]
+
+\startbuffer
+One can for instance \goto {reset the form} [ResetForm] or
+\goto {part of the form} [ResetForm{AllUglies}]. This last
+sentence was typed in as:
+\stopbuffer
+
+A special case of the check type field is a pure {\em push}
+field. Such a field has no export value and has only use as
+a pure interactive element. For the moment, let's forget
+about that one.
+
+Before we demonstrate our last type of fields and show some
+more tricky things, we need to discuss what to do with the
+information provided by filling in the fields. There are
+several actions available related to fields.
+
+\getbuffer
+
+\typebuffer
+
+Hereby \type {AllUglies} is a set of fields to be defined
+on forehand, using
+
+\typebuffer[uglies]
+
+In a similar way one can \goto {submit some or all fields}
+[SubmitForm] using the \type {SubmitForm} directive. This
+action optionally can take two arguments, the first being
+the destination, the second a list of fields to submit, for
+instance:
+
+\starttyping
+\button{submit}[SubmitForm{mailto::pragma@wxs.nl,AllUglies}]
+\stoptyping
+
+Once the fields are submitted (or saved in a file), we can
+convert the resulting \FDF\ file into something \TEX\ with
+the perl program \type{fdf2tex}. One can use \type
+{\ShowFDFFields{filename}} to typeset the values. If you do
+not want to run the \PERL\ converter from within \TEX, say
+\type {\runFDFconverterfalse}. In that case, the (stil)
+less robust \TEX\ based converter will be used.
+
+I already demonstrated how to attach scripts to events, but
+how about changing the appearance of the button itself?
+Consider the next definitions:
+
+\startbuffer
+\definesymbol [my-y] [$\times$]
+\definesymbol [my-r] [?]
+\definesymbol [my-d] [!]
+
+\definefield
+  [my-check] [check] [my-setup]
+  [{my-y,my-r,my-d},{,my-r,my-d}]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+Here we omitted the default value, which always is {\em no}
+by default. The setup can look like this:
+
+\startbuffer
+\setupfield
+  [my-setup]
+  [width=1.5cm, height=1.5cm,
+   frame=on, framecolor=red, rulethickness=1pt,
+   backgroundoffset=2pt, background=screen, backgroundscreen=.85]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+Now when this field shows up, watch what happens when the
+mouse enters the region and what when we click.
+
+\startbaselinecorrection
+\hbox to \hsize{\hss\field[my-check]\hss}
+\stopbaselinecorrection
+
+So, when instead of something \type{[yes,no]} we give
+triplets, the second element of such a triplet declares the
+roll||over appearance and the third one the push||down
+appearance. The braces are needed!
+
+One application of appearances is to provide help or
+additional information. Consider the next definition:
+
+\startbuffer
+\definefield [Help] [check] [HelpSetup] [helpinfo] [helpinfo]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+This means as much as: define a check field, typeset this
+field using the help specific setup and let \type{helpinfo}
+be the on||value as well as the default. Here we use the
+next setup:
+
+\startbuffer
+\setupfields
+  [reset]
+\setupfield
+  [HelpSetup]
+  [width=fit,height=fit,frame=off,option={readonly,hidden}]
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+
+We didn't use options before, but here we have to make sure
+that users don't change the content of the field and by
+default we don't want to show this field at all. The actual
+text is defined as a symbol:
+
+\startbuffer
+\definesymbol [helpinfo] [\SomeHelpText]
+
+\def\SomeHelpText%
+  {\framed
+     [width=\leftmarginwidth,height=fit,align=middle,style=small,
+      frame=on,background=color,backgroundcolor=white,framecolor=red]
+     {Click on the hide button to remove this screen}}
+\stopbuffer
+
+\typebuffer
+
+\getbuffer
+

+\inmargin {\fitfield[Help]} Now we can put the button somewhere and
+turn the help on or off by saying \goto {Hide Help} [HideField{Help}]
+or \goto {Show Help} [ShowField{Help}]. Although it's better to put
+these commands in a dedicated part of the screen. And try \goto

+We can place a field anywhere on the page, for instance by
+using the \type {\setup...texts} commands. Here we simply
+said:
+
+\typebuffer
+
+When one uses for instance \type {\setup...texts}, one
+often wants the help text to show up on every next page.
+This can be accomplished by saying:
+
+\starttyping
+\definemainfield [Help] [check] [HelpSetup] [helpinfo] [helpinfo]
+\stoptyping
+
+Every time such a field is called again, a new copy is
+generated automatically. Because fields use the
+objectreference mechanism and because such copies need to
+be known to their parent, field inclusion is a multi||pass
+typesetting job (upto 4 passes can be needed!).
+
+When possible, appearances are shared between fields,
+mainly because this saves space, but at the cost of extra
+object references. This feature is not that important for
+straight forward forms, but has some advantages when
+composing more complicated (educational) documents.
+
+Let us now summarize the commands we have available for
+defining and typesetting fields. The main definition macro
+is:
+
+\setup{definefield}
+
+and for radiofields we need to define the components by:
+
+\setup{definesubfield}
+
+Fields can be cloned and copied, where the latter can not
+be set up independently.
+
+\setup{clonefield}
+
+\setup{copyfield}
+
+Fields can be grouped, and such a group can have its own
+settings. Apart from copied fields, we can define the
+layout of a field and set options using:
+
+\setup{setupfield}
+
+Such a group inherits its settings from the general setup
+command:
+
+\setup{setupfields}
+
+Fields are placed using one of:
+
+\setup{field}
+
+or
+
+\setup{fitfield}
+
+Some pages back I showed an example of:
+
+\setup{fillinfield}
+
+Finally there are two commands to trace fields. These
+commands only make sense when one already has said: \type
+{\tracefieldstrue}.
+
+\setup{showfields}
+
+\setup{logfields}
+
+\section{Tooltips}
+
+\startbuffer
+Chinese people seem to have no problems in recognizing their many
+different pictorial glyphs. \tooltip [left] {Western} {European
+and American} people however seem to have problems in understanding
+what all those \tooltip [middle] {icons} {small graphics} on their
+computer screens represent. But, instead of standardizing on a set
+of icons, computer programmers tend to fill the screen with so
+called tooltips. Well, \tooltip {\CONTEXT} {a \TEX\ macro package}
+can do tooltips too, and although a good design can do without them,
+\TEX\ at least can typeset them correctly.
+\stopbuffer
+
+\getbuffer
+
+The previous paragraph has three of such tooltips under
+{\em western}, {\em icons} and {\em \CONTEXT}, each aligned
+differently. We just typed:
+
+\typebuffer
+
+This is an official command, and thereby we can show its
+definition:
+
+\setup{tooltip}
+
+\section{Fieldstacks}
+
+In due time I will provide more dedicated field commands.
+Currently apart from \type {\fillinfield} and \type
+{\tooltip} we have \type {\fieldstack}. Let's spend a few
+words on those now.

+sort of walk over different alternatives of the same
+graphic. This illustration was typeset by saying:
+
+\typebuffer[somemap3]
+
+However, before we can ask for such a map, we need to
+define a field set, which in fact is a list of symbols to
+show. This list is defined using:
+
+\typebuffer[somemap2]

+

+The sequences of characters at some point are extended with \nod {disc} nodes
+that relate to hyphenation. After that font logic can be applied and we get a
+list where some characters can be replaced, for instance multiple characters can

+font properties.
+
+Boxes (like \prm {hbox} and \prm {vbox}) become \nod {hlist} or \nod {vlist}

+So, to summarize: all that you enter as content eventually becomes a node, often

+\TEX82 (including \PDFTEX) differentiates between \type {char} nodes and \type
+{lig} nodes. The former are simple items that contained nothing but a \quote
 {character} and a \quote {font} field, and they lived in the same memory as
 tokens did. The latter also contained a list of components, and a subtype
 indicating whether this ligature was the result of a word boundary, and it was
 stored in the same place as other nodes like boxes and kerns and glues.
 
 In \LUATEX, these two types are merged into one, somewhat larger structure called
-a \type {glyph_node}. Besides having the old character, font, and component
-fields, and the new special fields like \quote {attr} (see~\in {section}
-[glyphnodes]), these nodes also contain:
+a \nod {glyph} node. Besides having the old character, font, and component

 In \LUATEX's main loop, almost all input characters that are to be typeset are
-converted into \type {glyph} node records with subtype \quote {character}, but
+converted into \nod {glyph} node records with subtype \quote {character}, but
 there are a few exceptions.
 
-First, the \type {\accent} primitives creates nodes with subtype \quote {glyph}
-instead of \quote {character}: one for the actual accent and one for the
-accentee. The primary reason for this is that \type {\accent} in \TEX82 is
-explicitly dependent on the current font encoding, so it would not make much
-sense to attach a new meaning to the primitive's name, as that would invalidate
-many old documents and macro packages. \footnote {Of course, modern packages will
-not use the \type {\accent} primitive at all but try to map directly on composed
-characters.} A secondary reason is that in \TEX82, \type {\accent} prohibits
-hyphenation of the current word. Since in \LUATEX\ hyphenation only takes place
-on \quote {character} nodes, it is possible to achieve the same effect.
-
-This change of meaning did happen with \type {\char}, that now generates \quote
-{glyph} nodes with a character subtype. In traditional \TEX\ there was a strong
-relationship between the 8|-|bit input encoding, hyphenation and glyphs taken
-from a font. In \LUATEX\ we have \UTF\ input, and in most cases this maps
-directly to a character in a font, apart from glyph replacement in the font
-engine. If you want to access arbitrary glyphs in a font directly you can always
-use \LUA\ to do so, because fonts are available as \LUA\ table.
-
-Second, all the results of processing in math mode eventually become nodes with
-\quote {glyph} subtypes.
-
-Third, the \ALEPH|-|derived commands \type {\leftghost} and \type {\rightghost}
-create nodes of a third subtype: \quote {ghost}. These nodes are ignored
-completely by all further processing until the stage where inter|-|glyph kerning
-is added.
-
-Fourth, automatic discretionaries are handled differently. \TEX82 inserts an
-empty discretionary after sensing an input character that matches the \type
-{\hyphenchar} in the current font. This test is wrong in our opinion: whether or
-not hyphenation takes place should not depend on the current font, it is a
-language property. \footnote {When \TEX\ showed up we didn't have \UNICODE\ yet
-and being limited to eight bits meant that one sometimes had to compromise
-between supporting character input, glyph rendering, hyphenation.}
-
-In \LUATEX, it works like this: if \LUATEX\ senses a string of input characters
-that matches the value of the new integer parameter \type {\exhyphenchar}, it will
-insert an explicit discretionary after that series of nodes. Initex sets the \type
-{\exhyphenchar=`\-}. Incidentally, this is a global parameter instead of a
-language-specific one because it may be useful to change the value depending on
-the document structure instead of the text language.
-
-The insertion of discretionaries after a sequence of explicit hyphens happens at
-the same time as the other hyphenation processing, {\it not\/} inside the main
-control loop.
-
-The only use \LUATEX\ has for \type {\hyphenchar} is at the check whether a word
-should be considered for hyphenation at all. If the \type {\hyphenchar} of the
-font attached to the first character node in a word is negative, then hyphenation
-of that word is abandoned immediately. This behaviour is added for backward
-compatibility only, and the use of \type {\hyphenchar=-1} as a means of
-preventing hyphenation should not be used in new \LUATEX\ documents.
-
-Fifth, \type {\setlanguage} no longer creates whatsits. The meaning of \type
-{\setlanguage} is changed so that it is now an integer parameter like all others.
-That integer parameter is used in \type {\glyph_node} creation to add language
-information to the glyph nodes. In conjunction, the \type {\language} primitive is
-extended so that it always also updates the value of \type {\setlanguage}.
-
-Sixth, the \type {\noboundary} command (that prohibits word boundary processing
-where that would normally take place) now does create nodes. These nodes are
-needed because the exact place of the \type {\noboundary} command in the input
-stream has to be retained until after the ligature and font processing stages.
-
-Finally, there is no longer a \type {main_loop} label in the code. Remember that
-\TEX82 did quite a lot of processing while adding \type {char_nodes} to the
-horizontal list? For speed reasons, it handled that processing code outside of
-the \quote {main control} loop, and only the first character of any \quote {word}
-was handled by that \quote {main control} loop. In \LUATEX, there is no longer a
-need for that (all hard work is done later), and the (now very small) bits of
-character|-|handling code have been moved back inline. When \type
-{\tracingcommands} is on, this is visible because the full word is reported,
-instead of just the initial character.

+    Automatic discretionaries are handled differently. \TEX82 inserts an empty
+    discretionary after sensing an input character that matches the \prm
+    {hyphenchar} in the current font. This test is wrong in our opinion: whether
+    or not hyphenation takes place should not depend on the current font, it is a
+    language property. \footnote {When \TEX\ showed up we didn't have \UNICODE\
+    yet and being limited to eight bits meant that one sometimes had to
+    compromise between supporting character input, glyph rendering, hyphenation.}
+
+    In \LUATEX, it works like this: if \LUATEX\ senses a string of input
+    characters that matches the value of the new integer parameter \prm
+    {exhyphenchar}, it will insert an explicit discretionary after that series of
+    nodes. Initially \TEX\ sets the \type {\exhyphenchar=`\-}. Incidentally, this
+    is a global parameter instead of a language-specific one because it may be
+    useful to change the value depending on the document structure instead of the
+    text language.
+
+    The insertion of discretionaries after a sequence of explicit hyphens happens
+    at the same time as the other hyphenation processing, {\it not\/} inside the
+    main control loop.
+
+    The only use \LUATEX\ has for \prm {hyphenchar} is at the check whether a
+    word should be considered for hyphenation at all. If the \prm {hyphenchar}
+    of the font attached to the first character node in a word is negative, then
+    hyphenation of that word is abandoned immediately. This behaviour is added
+    for backward compatibility only, and the use of \type {\hyphenchar=-1} as a
+    means of preventing hyphenation should not be used in new \LUATEX\ documents.

+    The \prm {setlanguage} command no longer creates whatsits. The meaning of

+    language information to the glyph nodes. In conjunction, the \prm {language}
+    primitive is extended so that it always also updates the value of \prm

+\stopitem
+
+\startitem
+    The \prm {noboundary} command (that prohibits word boundary processing

+\topicindex {math+spacing}
+
+Inline math is surrounded by (optional) \prm {mathsurround} spacing but that is a fixed
+dimension. There is now an additional parameter \lpr {mathsurroundskip}. When set to a
+non|-|zero value (or zero with some stretch or shrink) this parameter will replace
+\prm {mathsurround}. By using an additional parameter instead of changing the nature
+of \prm {mathsurround}, we can remain compatible. In the meantime a bit more
+control has been added via \lpr {mathsurroundmode}. This directive can take 6 values
+with zero being the default behaviour.

+Method six omits the surround glue when there is (x)spacing glue present while
+method seven does the opposite, the glue is only applied when there is (x)space
+glue present too. Anything more fancy, like checking the begining or end of a
+paragraph (or edges of a box) would not be robust anyway. If you want that you
+can write a callback that runs over a list and analyzes a paragraph. Actually, in
+that case you could also inject glue (or set the properties of a math node)
+explicitly. So, these modes are in practice mostly useful for special purposes
+and experiments (they originate in a tracker item). Keep in mind that this glue
+is part of the math node and not always treated as normal glue: it travels with
+the begin and end math nodes. Also, method 6 and 7 will zero the skip related
+fields in a node when applicable in the first occasion that checks them

+Normally you will force delimiters to certain sizes by putting an empty box or
+rule next to it. The resulting delimiter will either be a character from the
+stepwise size range or an extensible. The latter can be quite differently
+positioned than the characters as it depends on the fit as well as the fact if
+the used characters in the font have depth or height. Commands like (plain \TEX
+s) \type {\big} need use this feature. In \LUATEX\ we provide a bit more control
+by three variants that support optional parameters \type {height}, \type {depth}
+and \type {axis}. The following example uses this:

+addition there is a new primitive \lpr {mathoption} which will be used for

 This option was introduced for testing purposes when the math engine got split
 code paths and it forces the engine to treat new fonts as old ones with respect
 to italic correction etc. There are no guarantees given with respect to the final
-result and unexpected side effects are not seens as bugs as they relate to font

 the reasons why plugging in callbacks that operate on nodes is quite fast too.

 traditional nodes. In fact, the fact that we use a simple basic datatype has the
 penalty that less checking can be done, but less checking is also the reason why
 it's somewhat faster. An important aspect is that one cannot mix both methods,
 but you can cast both models. So, multiplying a node number makes no sense.

+\libindex{set_properties_mode}
+
+Attributes are a convenient way to relate extra information to a node. You can
+assign them at the \TEX\ end as well as at the \LUA\ end and and consult them at
+the \LUA\ end. One big advantage is that they obey grouping. They are linked
+lists and normally checking for them is pretty efficient, even if you use a lot
+of them. A macro package has to provide some way to manage these attributes at the
+\TEX\ end because otherwise clashes in their usage can occur.
+
+Each node also can have a properties table and you can assign values to this
+table using the \type {setproperty} function and get properties using the \type
+{getproperty} function. Managing properties is way more demanding than managing
+attributes.
+
+Take the following example:
+
+\starttyping
+\directlua {
+    local n = node.new("glyph")
+
+    node.setproperty(n,"foo")
+    print(node.getproperty(n))
+
+    node.setproperty(n,"bar")
+    print(node.getproperty(n))
+
+    node.free(n)
+}
+\stoptyping
+
+This will print \type {foo} and \type {bar} which in itself is not that useful
+when multiple mechanisms want to use this feature. A variant is:
+
+\starttyping
+\directlua {
+    local n = node.new("glyph")
+
+    node.setproperty(n,{ one = "foo", two = "bar" })
+    print(node.getproperty(n).one)
+    print(node.getproperty(n).two)
+
+    node.free(n)
+}
+\stoptyping
+
+This time we store two properties with the node. It really makes sense to have a
+table as property because that way we can store more. But in order for that to
+work well you need to do it this way:
+
+\starttyping
+\directlua {
+    local n = node.new("glyph")
+
+    local t = node.getproperty(n)
+
+    if not t then
+        t = { }
+        node.setproperty(n,t)
+    end
+    t.one = "foo"
+    t.two = "bar"
+
+    print(node.getproperty(n).one)
+    print(node.getproperty(n).two)
+
+    node.free(n)
+}
+\stoptyping
+
+Here our own properties will not overwrite other users properties unless of
+course they use the same keys. So, eventually you will end up with something:
+
+\starttyping
+\directlua {
+    local n = node.new("glyph")
+
+    local t = node.getproperty(n)
+
+    if not t then
+        t = { }
+        node.setproperty(n,t)
+    end
+    t.myself = { one = "foo", two = "bar" }
+
+    print(node.getproperty(n).myself.one)
+    print(node.getproperty(n).myself.two)
+
+    node.free(n)
+}
+\stoptyping
+
+This assumes that only you use \type {myself} as subtable. The possibilities are
+endless but care is needed. For instance, the generic font handler that ships
+with \CONTEXT\ uses the \type {injections} subtable and you should not mess with
+that one!
+
+There are a few helper functions that you normally should not touch as user: \typ
+{flush_properties_table} will wipe the table (normally a bad idea), \typ
+{get_properties_table} and will give the table that stores properties (using
+direct entries) and you can best not mess too much with that one either because
+\LUATEX\ itself will make sure that entries related to nodes will get wiped when
+nodes get freed, so that the \LUA\ garbage collector can do its job. In fact, the
+main reason why we have this mechanism is that it saves the user (or macro
+package) some work. One can easily write a property mechanism in \LUA\ where
+after a shipout properties gets cleaned up but it's not entirely trivial to make
+sure that with each freed node also its properties get freed, due to the fact
+that there can be nodes left over for a next page. And having a callback bound to
+the node deallocator would add way to much overhead.
+
+Managing properties in the node (de)allocator functions is disabled by default
+and is enabled by:
+
+\starttyping
+node.set_properties_mode(true)
+\stoptyping
+
+When we copy a node list that has a table as property, there are several possibilities: we do the same as
+a new node, we copy the entry to the table in properties (a reference), we do
+a deep copy of a table in the properties, we create a new table and give it
+the original one as a metatable. After some experiments (that also included
+timing) with these scenarios we decided that a deep copy made no sense, nor
+did nilling. In the end both the shallow copy and the metatable variant were
+both ok, although the second one is slower. The most important aspect to keep
+in mind is that references to other nodes in properties no longer can be
+valid for that copy. We could use two tables (one unique and one shared) or
+metatables but that only complicates matters.
+
+When defining a new node, we could already allocate a table but it is rather easy
+to do that at the lua end e.g.\ using a metatable \type {__index} method. That
+way it is under macro package control. When deleting a node, we could keep the
+slot (e.g. setting it to false) but it could make memory consumption raise
+unneeded when we have temporary large node lists and after that only small lists.
+Both are not done.
+
+So in the end this is what happens now: when a node is copied, and it has a table
+as property, the new node will share that table. If the second argument of \typ
+{set_properties_mode} is \type {true} then a metatable approach is chosen: the
+copy gets its own table with the original table as metatable. If you use the
+generic font loader the mode is enabled that way.
+
+A few more xperiments were done. For instance: copy attributes to the properties
+so that we have fast access at the \LUA\ end. In the end the overhead is not
+compensated by speed and convenience, in fact, attributes are not that slow when
+it comes to accessing them. So this was rejected.
+
+Another experiment concerned a bitset in the node but again the gain compared to
+attributes was neglectable and given the small amount of available bits it also
+demands a pretty strong agreement over what bit represents what, and this is
+unlikely to succeed in the \TEX\ community. It doesn't pay off.
+
+Just in case one wonders why properties make sense: it is not so much speed that
+we gain, but more convenience: storing all kind of (temporary) data in attributes
+is no fun and this mechanism makes sure that properties are cleaned up when a
+node is freed. Also, the advantage of a more or less global properties table is
+that we stay at the \LUA\ end. An alternative is to store a reference in the node
+itself but that is complicated by the fact that the register has some limitations
+(no numeric keys) and we also don't want to mess with it too much.

+\topicindex{\LUA}
+
+This is a reference manual, not a tutorial. This means that we discuss changes
+relative to traditonal \TEX\ and also present new functionality. As a consequence
+we will refer to concepts that we assume to be known or that might be explained
+later.
+
+The average user doesn't need to know much about what is in this manual. For
+instance fonts and languages are normally dealt with in the macro package that
+you use. Messing around with node lists is also often not really needed at the
+user level. If you do mess around, you'd better know what you're dealing with.
+Reading \quotation {The \TEX\ Book} by Donald Knuth is a good investment of time
+then also because it's good to know where it all started. A more summarizing
+overview is given by \quotation {\TEX\ by Topic} by Victor Eijkhout. You might
+want to peek in \quotation {The \ETEX\ manual} and documentation about \PDFTEX.
+
+But \unknown\ if you're here because of \LUA, then all you need to know is that
+you can call it from within a run. The macro package that you use probably will
+provide a few wrapper mechanisms but the basic \lpr {directlua} command that
+does the job is:
+
+\starttyping
+\directlua{tex.print("Hi there")}
+\stoptyping
+
+You can put code between curly braces but if it's a lot you can also put it in a
+file and load that file with the usual \LUA\ commands.
+
+If you still decide to read on, then it's good to know what nodes are, so we do a
+quick introduction here. If you input this text:
+
+\starttyping
+Hi There
+\stoptyping
+
+eventually we will get a linked lists of nodes, which in \ASCII\ art looks like:
+
+\starttyping
+H <=> i <=> [glue] <=> T <=> h <=> e <=> r <=> e
+\stoptyping
+
+When we have a paragraph, we actually get something:
+
+\starttyping
+[localpar] <=> H <=> i <=> [glue] <=> T <=> h <=> e <=> r <=> e <=> [glue]
+\stoptyping
+
+Each character becomes a so called glyph node, a record with properties like the
+current font, the character code and the current language. Spaces become glue
+nodes. There are many node types that we will discuss later. Each node points
+back to a previous node or next node, given that these exist.
+
+It's also good to know beforehand that \TEX\ is basically centered around
+creating paragraphs and pages. The par builder takes a list and breaks it into
+lines. We turn horizontal material into vertical. Lines are so called boxes and
+can be separated by glue, penalties and more. The page builder accumulates lines
+and when feasible triggers an output routine that will take the list so far.
+Constructing the actual page is not part of \TEX\ but done using primitives that
+permit manipulation of boxes. The result is handled back to \TEX\ and flushed to
+a (often \PDF) file.
+
+The \LUATEX\ engine provides hooks for \LUA\ code at nearly every reasonable
+point in the process: collecting content, hyphenating, applying font features,
+breaking into lines, etc. This means that you can overload \TEX's natural
+behaviour, which still is the benchmark. When we refer to \quote {callbacks} we
+means these hooks.
+
+Where plain \TEX\ is basically a basic framework for writing a specific style,
+macro packages like \CONTEXT\ and \LATEX\ provide the user a whole lot of
+additional tools to make documents look good. They hide the dirty details of font
+management, language demands, turning structure into typeset results, wrapping
+pages, including images, and so on. You should be aware of the fact that when you
+hook in your own code to manipulate lists, this can interfere with the macro
+package that you use.
+
+When you read about nodes in the following chapters it's good to keep in mind their
+commands that relate to then. Here are a few:

+In this section we will discuss a potential conflict with other mechanisms,

+function MP.AnExample(str)
+    mp.aux.quoted(string.reverse(str))

+The \type {mp} namespace is reserved for functionality provided by \CONTEXT\
+itself so you should not polute it with your own code. Instead use the \type {MP}
+namespace and mix in some uppercase characters.
+
+Here you see a subnamespace \type {aux} which is where officially the helpers are
+organized but they are also accessible directly (as shown in previous sections).
+The reason for the \type {aux} namespace is, apart from propection aginst
+redefinition, also that we have \type {get} and \type {set} namespaces and there
+might be more in the future. At the \LUA\ end you can best use these namespaces
+because they are less likely to be accidentally overwritten by user code.
+
+As mentioned, there can still be conflicts. For instance the following will not
+work:
+
+\startbuffer
+\startluacode
+function MP.reverse(str)
+    mp.aux.quoted(string.reverse(str))

+
+\typebuffer
+
+% \startlinecorrection
+% \getbuffer
+% \stoplinecorrection
+
+The reason is that \type {reverse} gets expanded as part of parsing the macro
+name and this command expects an expression. A way out of this is the following:
+
+\startbuffer
+\startluacode
+function MP.reverse(str)
+    mp.aux.quoted(string.reverse(str))

+In most cases such \type {lua.mp.command()} calls have a \METAPOST\ macro with

+\stopsection
+
+\startsection[title=Large paths]
+
+The plugins (like those dealing with text) also use calls in the \type {mp}
+namespace but they have sort of protected names, starting with \type {mf_}. These
+are visible but not meant to be used by users. Not only can their name change,
+their functionality can as well.
+
+The following are actually private as they have related macros but also have a
+public alias:
+
+\startlines
+lua.mp.pathlength(name)
+lua.mp.pathpoint(i)
+lua.mp.pathleft(i)
+lua.mp.pathright(i)
+lua.mp.pathreset()
+\stoplines
+
+They are meant for special high|-|performance path access, for example:
+
+\startlinecorrection
+\startMPcode
+    save p, q, r;
+    path p ; p := for i=1 upto 1000 :
+        (i,0) -- (i,4 + uniformdeviate 4) --

+\stopMPcode
+\stoplinecorrection
+
+Because a lookup of a point in \METAPOST\ is a linear lookup over a linked list
+for very large paths the gain is significant when using \LUA\ because there the
+points are stored in an indexed table. The left and right points can be used
+vebose like
+
+\starttyping
+lua.mp.pathpoint(i) controls lua.mp.pathleft(i) and lua.mp.pathright(i)
+\stoptyping
+
+or more terse:
+
+\starttyping
+pointof i controls leftof i and rightof i
+\stoptyping
+
+Beware: this kind of trickery is {\em only} needed when you have very large paths
+that are to be manipulated and the. Otherwise it's overkill.
+
+\stopsection
+
+\startsection[title={Interfacing to \TEX}]
+
+The next bunch of calls is for accessing \TEX\ registers. You can set their
+values and get them as well.
+
+\starttyping
+lua.mp.getmacro(k)
+lua.mp.getdimen(k)
+lua.mp.getcount(k)
+lua.mp.gettoks (k)

+
+When you mess around with variables and run into issues it might help to
+report values on the console. The \type {report} function does this:
+
+\starttyping
+lua.mp.report(a,b)
+\stoptyping
+
+\startlinecorrection
+\startMPcode
+lua.mp.report("status","a circle") ;

+    xpart llcorner currentpicture, ypart llcorner currentpicture,

+) ;
+draw boundingbox currentpicture withcolor blue ;
+report("status","the size: @Nbp x @Nbp",
+    bbwidth(currentpicture), bbheight(currentpicture)
+) ;
+message("done") ;
+\stopMPcode
+\stoplinecorrection
+
+The console shows:
+
+\starttyping
+metapost > status : a circle
+metapost > status : its boundingbox [-28.34645,-14.17323,28.34645,14.17323]
+metapost > status : the size: 57.1929bp x 28.84647bp
+metapost > message : done
+\stoptyping
+
+There are two more getters. These can be used to access the specific graphic
+related variables set at the \TEX\ end.
+
+\starttyping
+mp.texvar(name)
+mp.texstr(name)
+\stoptyping
+
+If you have adaptive styles you might want to test for modes.
+
+\starttyping
+if lua.mp.mode("screen") : % or processingmode
+    % some action only needed for screen documents
+fi ;
+if lua.mp.systemmode("first") :
+    % some action for the first run
+fi ;
+\stoptyping
+
+For convenience these are wrapped into macros:
+
+\starttyping
+if texmode("screen") :
+    % some action only needed for screen documents
+fi ;
+if systemmode("first") :
+    % some action for the first run
+fi ;
+\stoptyping
+
+When you implement your own helpers you can fall back on some auxiliary functions
+in the \type {mp} namespace. Actually these are collected in \type {mp.aux} and
+thereby protected from being overwritten by mistake. Here they are:
+
+% mp.flush()
+% mp.size(t)
+
+\stopsection
+
+\startsection[title={Interfacing to \METAPOST}]
+
+There is also experimental access to some of the \METAPOST\ internals. In order
+to deal with (large) paths a few more iterator related helpers are provided too.
+
+% mp.set (numeric string path boolean)
+
+\starttyping
+n = mp.getnumeric(name)
+s = mp.getstring(name)
+b = mp.getboolean(name)
+p = mp.getpath(name)
+\stoptyping
+
+A is path a table of tables that have six values: the coordinates and the
+pre- and postcontrol. You can manipulate this table and feed it back into
+\METAPOST.
+
+\startlinecorrection
+\startMPcode
+numeric n ; n := lua.mp.newhash() ;
+
+for i=1 upto 3 :
+    lua.mp.tohash(n,i) ;

+    if lua.mp.inhash(n,3) : green else : red fi ;
+
+fill fullcircle scaled 5mm withcolor
+    if lua.mp.inhash(n,4) : green else : red fi ;
+
+lua.mp.disposehash(n)
+\stopMPcode
+\stoplinecorrection
+
+You can also store values with keys and access them later:
+
+\startlinecorrection
+\startMPcode
+numeric n ; n := lua.mp.newhash() ;
+
+for i=1 upto 3 :
+    lua.mp.tohash(n,i,decimal sqrt(i)) ;
+endfor ;
+
+draw textext(lua.mp.fromhash(n,3))
+    ysized 1cm
+    withcolor blue ;
+
+lua.mp.disposehash(n)
+\stopMPcode
+\stoplinecorrection
+
+You can also name your own hash:
+
+\startlinecorrection
+\startMPcode
+lua.mp.newhash("foo") ;
+
+for i=1 upto 3 :
+    lua.mp.tohash("foo",i,decimal sqrt(i)) ;
+endfor ;
+
+draw textext(lua.mp.fromhash("foo",2))
+    ysized 1cm
+    withcolor green ;
+
+lua.mp.disposehash("foo")
+\stopMPcode
+\stoplinecorrection
+
+Although it might look like \METAPOST\ supports arrays the reality is that it
+doesn't really. There is a concept of suffixes but internally these are just a
+way to compose macros. The following test is one that is used in one of the
+\METAFUN\ modules written by Alan Braslau.
+
+\startlinecorrection
+\startMPcode
+path p, q[] ;
+
+if lua.mp.isarray(str q[1]) :
+    fill fullcircle scaled 1cm withcolor red ;
+    draw textext(lua.mp.prefix(str q[1])) withcolor white;
+else :
+    fill fullsquare scaled 1cm withcolor blue ;
+fi ;
+
+currentpicture := currentpicture shifted (-2cm,0) ;
+
+if lua.mp.isarray(str p) :
+    fill fullcircle scaled 1cm withcolor red ;
+else :
+    fill fullsquare scaled 1cm withcolor blue ;
+fi ;
+\stopMPcode
+\stoplinecorrection
+
+Another helper relates to extensions that \METAFUN\ adds to \METAPOST. When you
+iterate over a picture you can recognize these as objects. The next code shows
+the \LUA\ call as well as the more convenient macro call. So, \type {textext}
+clearly is a foreign object.
+
+\startlinecorrection
+\startMPcode
+picture p ; p := image (
+    fill fullcircle scaled 1cm withcolor red ;

+\startsection[title={The theme}]
+
+Nearly always \TEX\ conferences carry a theme. As there have been many
+conferences the organizers have run out of themes involving fonts, macros and
+typesetting and are now cooking up more fuzzy ones. Take the Bacho\TUG\ 2017
+theme:
+
+\startnarrower[left,8*right] \startpacked
+\startpresomething {Premises}
+    The starting point, what we have, what do we use, what has been achieved?
+\stoppresomething
+\startpresomething {Predilections}
+    How do we act now, how do we want to act, what is important to us and what do
+    we miss?
+\stoppresomething
+\startpresomething {Predictions}
+    What is the future of \TEX, what we'd like to achieve and can we influence
+    it?
+\stoppresomething
+\stoppacked \stopnarrower
+
+My first impression with these three P words was: what do they mean? Followed by
+the thought: this is no longer a place to take kids to. But the Internet gives
+access to the Cambridge Dictionary, so instead of running to the dusty meter of
+dictionaries somewhere else in my place, I made sure that I googled the most
+recent definitions:
+
+\startnarrower[left] \startpacked
+\startpresomething {premise}
+    an idea or theory on which a statement or action is based
+\stoppresomething
+\startpresomething {predilection}
+    if someone has a predilection for something, they like it a lot
+\stoppresomething
+\startpresomething {prediction}
+    a statement about what you think will happen in the future
+\stoppresomething
+\stoppacked \stopnarrower
+
+I won't try to relate these two sets of definitions but several words stand out
+in the second set: idea, theory, action, like, statement and future. Now, as a
+preparation for the usual sobering thoughts that Jerzy, Volker and I have when we
+staring into a Bacho\TEX\ campfire I decided to wrap up some ideas around these
+themes and words. The books that I will mention are just a selection of what you
+can find distributed around my place. This is not some systematic research but
+just the result of a few weeks making a couple of notes while pondering about
+this conference.
+
+\stopsection
+
+\startsection[title=Introduction]
+
+One cannot write the amount of \TEX\ macros that I've written without also liking
+books. If you look at my bookshelves the topics are somewhat spread over the
+possible spectrum of topics: history, biology, astronomy, paleontology, general
+science but surprisingly little math. There are a bunch of typography|-|related
+books but only some have been read: it's the visuals that matter most and as
+there are no real developments I haven't bought new ones in over a decade,
+although I do buy books that look nice for our office display but the content
+should be interesting too. Of course I do have a couple of books about computer
+(related) science and technology but only a few are worth a second look.
+Sometimes I bought computer books expecting to use them (in some project) but I
+must admit that most have not been read and many will soon end up in the paper
+bin (some already went that way). I'll make an exception for Knuth, Wirth and a
+few other fundamental ones that I (want to) read. And, I need to catch up on deep
+learning, so that might need a book.
+
+My colleagues and I have many discussions, especially about what we read, and
+after a few decades one starts seeing patterns. Therefore the last few years it
+was a pleasant surprise for me to run into books and lectures that nicely
+summarize what one has noticed and discussed in a consistent way. My memory is
+not that good, but good enough to let some bells ring.

+
+The first book that gave me this \quotation {finally a perfect summary of
+historic developments} feeling is \quotation{Sapiens} by Yuval Noah Harari. The
+author summarizes human history from a broad perspective where modern views on
+psychology, anthropology and technical developments are integrated. It's a follow
+up on a history writing trend started by Jared Diamond. The follow up \quotation
+{Homo Deus} looks ahead and is just as well written. It also integrates ideas
+from other fields, for instance those related to development of artificial
+intelligence (Dennett, Bostrom, etc.).
+
+Another inspiration for this talk and article is the 50 hour lecture series on
+behavioral biology by Robert Sapolsky of Stanford University, brought to my
+attention by my nephew Bram who visited a few \TEX\ conferences with me and who
+is now also forced to use \TEX\ for assignments and reports. (How come
+self|-|published books used at universities often look so bad?)
+
+The title of this talk is inspired by the book \quotation {Children of Time} by
+Adrian Tchaikovsky that I read recently. There are science fiction writers who
+focus on long term science and technology, such as some of Alastair Reynolds,
+while others follow up on recent development in all kind of sciences. One can
+recognize aspects of \quotation {Superintelligence} by Bostrom in Neal Asher's
+books, insights in psychology in the older Greg Bear books, while in the
+mentioned \quotation {Children of Time} (socio)biological insights dominate. The
+main thread in that book is the development of intelligence, social behaviour,
+language, script and cooperation in a species quite different from us: spiders.
+It definitely avoids the anthropocentric focus that we normally have.
+
+So how does this relate to the themes of the Bacho\TEX\ conference? I will pick
+out some ways to approach them using ideas from the kind of resources mentioned
+above. I could probably go on and on for pages because once you start relating
+what you read and hear to this \TEX\ ecosystem and community, there is no end.
+So, consider this a snapshot, that somehow relates to the themes:
+
+\startnarrower[left,8*right] \startpacked

+    Let's look at what the live sciences have to say about \TEX\ and friends and
+    let's hope that I don't offend the reader and the field.
+\stoppresomething
+\startpresomething {predilection}
+    Let's figure out what brings us here to this place deeply hidden in the woods,
+    a secret gathering of the \TEX\ sect.
+\stoppresomething
+\startpresomething {prediction}
+    Let's see if the brains present here can predict the future because after
+    all, according to Dennett, that is what brains are for.

+At school I was already intrigued by patterns in history: a cyclic, spiral and
+sinusoid social evolution instead of a pure linear sequence of events. It became
+my first typeset|-|by|-|typewriter document: Is history an exact science? Next I
+will use and abuse patterns and ideas to describe the \TEX\ world, not wearing a
+layman's mathematical glasses, but more from the perspective of live sciences,
+where chaos dominates.

+\startsection[title={The larger picture}]
+
+History of mankind can be roughly summarized as follows. For a really long time
+we were hunters but at some point (10K years ago) became farmers. As a result we
+could live in larger groups and still feed them. The growing complexity of
+society triggered rules and religion as instruments for stability and
+organization (I use the term religion in its broadest sense here). For quite a
+while cultures came and went, and climate changes are among the reasons.
+
+After the industrial revolution new religions were invented (social, economic and
+national liberalism) and we're now getting dataism (search for Harari on youtube
+for a better summary). Some pretty great minds seem to agree that we're heading
+to a time when humans as we are will be outdated. Massive automation, interaction
+between the self and computer driven ecosystems, lack of jobs and purpose,
+messing around with our genome. Some countries and cultures still have to catch
+up on the industrial revolution, if they manage at all, and maybe we ourselves
+will be just as behind reality soon. Just ask yourself: did you manage to catch
+up? Is \TEX\ a stone age tool or a revolutionary turning point?
+
+A few decades ago a trip to Bacho\TEX\ took more than a day. Now you drive there
+in just over half a day. There was a time that it took weeks: preparation,
+changing horses, avoiding bad roads. Not only your own man|-|hours were involved.
+It became easier later (my first trip took only 24 hours) and recently it turned
+into a piece of cake: you don't pick up maps but start your device; you don't
+need a travel agent but use the Internet; there are no border patrols, you can
+just drive on. (Okay, maybe some day soon border patrols at the Polish border
+show up again, just like road tax police in Germany, but that might be a
+temporary glitch.)
+
+Life gets easier and jobs get lost. Taxi and truck drivers, travel agents, and
+cashiers become as obsolete as agricultural workers before. Next in line are
+doctors, lawyers, typesetters, printers, and all those who think they're safe.
+Well, how many people were needed 400 years ago to produce the proceedings of a
+conference like this in a few days' time span? Why read the introduction of a
+book or a review when you can just listen to the author's summary on the web? How
+many conferences still make proceedings (or go for videos instead), will we
+actually need editors and typesetters in the future? How much easier has it
+become to design a font, including variants? What stories can designers tell in
+the future when programs do the lot? The narrower your speciality is, the worse
+are your changes; hopefully the people present at this conference operate on a
+broader spectrum. It's a snapshot. I will show some book covers as reference but
+am aware that years ago or ahead the selection could have been different.

+\startsection[title=Words]
+
+Words (whatever they represent) found a perfect spot to survive: our minds. Then
+they made it from speech (and imagination) into writing: carved in stone, wood,
+lead. At some point they managed to travel over wires but no matter what
+happened, they are still around. Typesetting as visualization is also still
+surrounding us so that might give us a starting point for ensuring a future for
+\TEX\ to work on, because \TEX\ is all about words. There is a lot we don't see;
+imagine if our eyes had microscopic qualities. What if we could hear beyond
+20KHz. Imagine we could see infrared. How is that with words. What tools, similar
+in impact as \TEX, can evolve once we figure that out. What if we get access to
+the areas of our brain that hold information? We went from print to screen and
+\TEX\ could cope with that. Can it cope with what comes next?
+
+The first printing press replaced literal copying by hand. Later we got these
+linotype|-|like machines but apart from a few left, these are already thrown out
+of windows (as we saw in a movie a few Bacho\TeX's ago). Photo|-|typesetting has
+been replaced too and because a traditional centuries old printing press is a
+nice to see item, these probably ring more bells than that gray metal closed box
+typesetters. Organizers of \TEX\ conferences love to bring the audience to old
+printing workshops and museums. At some point computers got used for typesetting
+and in that arena \TEX\ found its place. These gray closed boxes are way less
+interesting than something mechanical that at least invites us to touch it. How
+excited can one be about a stack of \TEX\,Live \DVD{}s?

+\startsection[title=Remembering]
+
+Two times I visited the part of the science museum in London with young family
+members: distracted by constantly swiping their small powerful devices, they
+didn't have the least interest in the exhibited computer related items, let alone
+the fact that the couch they were sitting on was a Cray mainframe. Later on,
+climbing on some old monument or an old cannon seemed more fun. So, in a few
+decades folks will still look at wooden printing presses but quickly walk through
+the part of an exhibition where the tools that we use are shown. We need to find
+ways to look interesting. But don't think we're unique: how many kids find
+graphical trend|-|setting games like Myst and Riven still interesting? On the
+other hand a couple of month ago a bunch of nieces and nephews had a lot of fun
+with an old Atari console running low|-|res bitmap games. Maybe there is hope for
+good old \TEX.
+
+If indeed we're heading to a radically different society one can argue if this
+whole discussion makes sense. When the steam engine showed up, the metaphor for
+what went on in our heads was that technology, It's a popular example of speakers
+on this topic: \quotation {venting off steam}. When electricity and radio came
+around metaphors like \quotation {being on the same wavelength} showed up. A few
+decades ago the computer replaced that model although in the meantime the model
+is more neurobiological: we're a hormone and neurotransmitter driven computer. We
+don't have memory the way computers do.
+
+How relevant will page breaks, paragraph and line breaks be in the future? Just
+like \quotation {venting off steam} may make no sense to the youth, asking a
+typesetter to \quotation {give me a break} might not make much sense soon.
+However, when discussing automated typesetting the question \quotation {are we on
+the same page} still has relevance.
+
+Typesetting with a computer might seem like the ultimate solution but it's
+actually rather dumb when we consider truly intelligent systems. On the large
+scale of history and developments what we do might get quite unnoticed. Say that
+mankind survives the next few hundred years one way or the other. Science fiction
+novels by Jack McDevitt have an interesting perspective of rather normal humans
+millennia ahead of us who look back on these times in the same way as we look
+back now. Nothing fundamental changed in the way we run society. Nearly nothing
+from the past is left over and apart from being ruled by \AI{}s people still do
+sort of what they do now. \TEX ? What is that? Well, there once was this great
+computer scientist Knuth (in the remembered row of names like Aristotle |<|I just
+started reading \quotation {The Lagoon} by Armand Leroi|>| Newton, Einstein, his
+will show up) who had a group of followers that used a program that he seems to
+have written. And even that is unlikely to be remembered, unless maybe user
+groups manage to organize an archive and pass that on. Maybe the fact that \TEX\
+was one of the first large scale open source programs, of which someone can study
+the history, makes it a survivor. The first program that was properly documented
+in detail! But then we need to make sure that it gets known and persists.
+
+\startsection[title=Automation]
+
+In a recent interview Daniel Dennett explains that his view of the mind as a big
+neural network, one that can be simulated in software on silicon, is a bit too
+simplistic. He wonders if we shouldn't more tend to think of a network of
+(selfish) neurons that group together in tasks and then compete with each other,
+if only because they want to have something to do.
+
+Maybe attempts to catch the creative mindset and working of a typesetter in
+algorithms is futile. What actually is great typography or good typesetting?
+Recently I took a look at my bookshelf wondering what to get rid of \emdash\
+better do that now than when I'm too old to carry the crap down (crap being
+defined as uninteresting content or bad looking). I was surprised about the
+on|-|the|-|average bad quality of the typesetting and print. It's also not really
+getting better. One just gets accustomed to what is the norm at a certain point.
+Whenever they change the layout and look and feel of the newspaper I read the
+arguments are readability and ease of access. Well, I never had such a hard time
+reading my paper as today (with my old eyes).
+
+Are we, like Dennett, willing to discard old views on our tools and models? When
+my first computer was a \RCA\ 1802 based kit, that had 256 bytes of memory. My
+current laptop (from 2013) is a Dell Precision workstation with an extreme quad
+core processor and 16 GB of memory and ssd storage. Before I arrived there I
+worked with \DECTEN, \VAX\ and the whole range of Intel \CPU{}s. So if you really
+want to compare a brain with a computer, take your choice.
+
+I started with \TEX\ on a 4 MHz desk top with 640 MB memory and a 10 MB hard
+disk. Running \CONTEXT\ \MKIV\ with \LUATEX\ on such a machine is no option at
+all, but I still carry the burden of trying to write efficient code (which is
+still somewhat reflected in the code that makes up \CONTEXT). In the decades that
+we have been using \TEX\ we had to adapt! Demands changed, possibilities changed,
+technologies changed. And they keep changing. How many successive changes can a
+\TEX\ user handle? Sometimes, when I look and listen I wonder.

+If you look back, that is, if you read about the tens of thousands of years that
+it took humans to evolve (\quotation {The mind in the cave} by Lewis|-|Williams
+is a good exercise) you realize even more in what a fast|-|paced time we live and
+that we're witnessing transitions of another magnitude.
+
+In the evolution of species some tools were invented multiple times, like eyes.
+You see the same in our \TEX\ world: multiple (sub)macro packages, different font
+technologies, the same solutions but with an alternative approach. Some
+disappear, some stay around. Just like different circumstances demand different
+solutions in nature, so do different situations in typesetting, for instance
+different table rendering solutions. Sometime I get the feeling that we focus too
+much on getting rid of all but one solution while more natural would be to accept
+diversity, like bio|-|diversity is accepted. Transitions nowadays happen faster
+but the question is if, like aeons before, we (have to) let them fade away. When
+evolution is discussed the terms \quote {random}, \quote {selection}, \quote
+{fit}, and so on are used. This probably also applies to typography: at some
+point a font can be used a lot, but in the end the best readable and most
+attractive one will survive. Newspapers are printed in many copies, but rare
+beautiful books hold value. Of course, just like in nature some developments
+force the further path of development, we don't suddenly grow more legs or digits
+on our hands. The same happens with \TEX\ on a smaller timescale: successors
+still have the same core technology, also because if we'd drop it, it would be
+something different and then give a reason to reconsider using such technology
+(which likely would result in going by another path).

+\startsection[title=Quality]
+
+Richard Dawkins \quotation {The Ancestor's Tale} is a non|-|stop read. In a
+discussion with Jared Diamond about religion and evolution they ponder this
+thread: you holding the hand of your mother who is handing her mother's hand and
+so on till at some point fish get into the picture. The question then is, when do
+we start calling something human? And a related question is, when does what we
+call morality creeps in? Is 50\% neanderthaler human or not?
+
+So, in the history of putting thoughts on paper: where does \TEX\ fit in? When do
+we start calling something automated typesetting? When do we decide that we have
+quality? Is \TEX\ so much different from its predecessors? And when we see
+aspects of \TEX\ (or related font technology) in more modern programs, do we see
+points where we cross qualitative or other boundaries? Is a program doing a
+better job than a human? Where do we stand? There are fields where there is no
+doubt that machines outperform humans. It's probably a bit more difficult in
+aesthetic fields except perhaps when we lower the conditions and expectations
+(something that happens a lot).
+
+For sure \TEX\ will become obsolete, maybe even faster that we think, but so will
+other typesetting technologies. Just look back and have no illusions. Till then
+we can have our fun and eventually, when we have more free time than we need, we
+might use it out of hobbyism. Maybe \TEX\ will be remembered by probably its most
+important side effect: the first large scale open source, the time when users met
+over programs, Knuth's disciples gathered in user groups, etc. The tools that we
+use are just a step in an evolution. And, as with evolution, most branches are
+pruned. So, when in the far future one looks back, will they even notice \TEX ?
+The ancestor's tail turns the tree upside down: at the end of the successful
+branch one doesn't see the dead ends.
+
+Just a thought: \CD{}s and media servers are recently being replaced (or at least
+accompanied) by Long Play records. In the shop where I buy my \CD{}s the space
+allocated to records grows at the cost of more modern media. So, maybe at some
+point retro|-|typesetting will pop up. Of course it might skip \TEX\ and end up
+at woodcutting or printing with lead.

+\startsection[title=What mission]
+
+We rely on search engines instead of asking around or browsing libraries. Do
+students really still read books and manuals or do they just search and listen to
+lectures. Harari claims that instead of teaching kids facts in school we should
+just take for granted that they can get all the data they want and that we should
+learn them how to deal with data and adapt to what is coming. We take for granted
+that small devices with human voices show us the route to drive to Bacho\TEX, for
+instance, although by now I can drive it without help. In fact, kids can surprise
+you by asking if we're driving in Germany when we are already in Poland.
+
+We accept that computer programs help physicians in analyzing pictures. Some wear
+watches that warn them about health issues, and I know a few people who monitor
+their sugar levels electronically instead of relying on their own measurements.
+We seem to believe and trust the programs. And indeed, we also believe that \TEX\
+does the job in the best way possible. How many people really understand the way
+\TEX\ works?
+
+We still have mailing lists where we help each other. There are also wikis and
+forums like stack exchange. But who says that even a moderate bit of artificial
+intelligence doesn't answer questions better. Of course there needs to be input
+(manuals, previous answers, etc.) but just like we need fewer people as workforce
+soon, the number of experts needed also can be smaller. And we're still talking
+about a traditional system like \TEX. Maybe the social experience that we have on
+these media will survive somehow, although: how many people are members of
+societies, participate in demonstrations, meet weekly in places where ideas get
+exchanged, compared to a few decades ago? That being said, I love to watch posts
+with beautiful \CONTEXT\ solutions or listen to talks by enthusiastic users who
+do things I hadn't expected. I really hope that this property survives, just like
+I hope that we will be able to see the difference between a real user's response
+and one from an intelligent machine (an unrealistic hope I fear). Satisfaction
+wins and just like our neurological subsystems at some point permanently adapt to
+thresholds (given that you trigger things often enough), we get accustomed to
+what \TEX\ provides and so we stick to it.

+\startsection[title={Intelligence versus consciousness}]
+
+Much of what we do is automated. You don't need to think of which leg to move and
+what foot to put down when you walk. Reacting to danger also to a large extent is
+automated. It doesn't help much to start thinking about how dangerous a lion can
+be when it's coming after you, you'd better move fast. Our limbic system is
+responsible for such automated behaviour, for instance driven by emotions. The
+more difficult tasks and thoughts about them happen in the frontal cortex (sort
+of).

+
+For most users \TEX\ is like the limbic system: there is not much thinking
+involved, and the easy solutions are the ones used. Just like hitting a nerve
+triggers a chain of reactions, hitting a key eventually produces a typeset
+document. Often this is best because the job needs to get done and no one really
+cares how it looks; just copy a preamble, key in the text and assume that it
+works out well (enough). It is tempting to compare \TEX's penalties, badness and
+other parameters with levels of hormones and neurotransmitters. Their function
+depends on where they get used and the impact can be accumulated, blocked or
+absent. It's all magic, especially when things interact.
+
+Existing \TEX\ users, developers and user groups of course prefer to think
+otherwise, that it is a positive choice by free will. That new users have looked
+around and arrived at \TEX\ for good reason: their frontal cortex steering a
+deliberate choice. Well, it might have played a role but the decision to use
+\TEX\ might in the end be due to survival skills: I want to pass this exam and
+therefore I will use that weird system called \TEX.
+
+All animals, us included, have some level of intelligence but also have this hard
+to describe property that we think makes us what we are. Intelligence and
+consciousness are not the same (at least we know a bit about the first but nearly
+nothing about the second). We can argue about how well composed some music is but
+why we like it is a different matter.
+
+We can make a well thought out choice for using \TEX\ for certain tasks but can
+we say why we started liking it (or not)? Why it gives us pleasure or maybe
+grief? Has it become a drug that we got addicted to? So, one can make an
+intelligent decision about using \TEX\ but getting a grip on why we like it can
+be hard. Do we enjoy the first time struggle? Probably not. Do we like the folks
+involved? Yes, Don Knuth is a special and very nice person. Can we find help and
+run into a friendly community? Yes, and a unique one too, annoying at times,
+often stimulating and on the average friendly for all the odd cases running
+around.
+
+Artificial intelligence is pretty ambitious, so speaking of machine intelligence
+is probably better. Is \TEX\ an intelligent program? There is definitely some
+intelligence built in and the designer of that program is for sure very
+intelligent. The designer is also a conscious entity: he likes what he did and
+finds pleasure in using it. The program on the other hand is just doing its job:
+it doesn't care how it's done and how long it takes: a mindless entity. So here
+is a question: do we really want a more intelligent program doing the job for us,
+or do those who attend conferences like Bacho\TEX\ enjoy \TEX ing so much that
+they happily stay with what they have now? Compared to rockets tumbling down
+and|/|or exploding or Mars landers thrashing themselves due to programming errors
+of interactions, \TEX\ is surprisingly stable and bug free.

+\startsection[title={Individual versus group evolution}]
+
+After listening for hours to Sapolsky you start getting accustomed to remarks
+about (unconscious) behaviour driven by genes, expression and environment, aimed
+at \quotation {spreading many copies of your genes}. In most cases that is an
+individual's driving force. However, cooperation between individuals plays a role
+in this. A possible view is that we have now reached a state where survival is
+more dependent on a group than on an individual. This makes sense when we
+consider that developments (around us) can go way faster than regular evolution
+(adaptation) can handle. We take control over evolution, a mechanism that needs
+time to adapt and time is something we don't give it anymore.
+
+Why does \TEX\ stay around? It started with an individual but eventually it's the
+groups that keeps it going. A too|-|small group won't work but too|-|large groups
+won't work either. It's a known fact that one can only handle some 150 social
+contacts: we evolved in small bands that split when they became too large. Larger
+groups demanded abstract beliefs and systems to deal with the numbers: housing,
+food production, protection. The \TEX\ user groups also provide some
+organization: they organize meetings, somehow keep development going and provide
+infrastructure and distributions. They are organized around languages. According
+to Diamond new languages are still discovered but many go extinct too. So the
+potential for language related user groups is not really growing.
+
+Some of the problems that we face in this world have become too large to be dealt
+with by individuals and nations. In spite of what anti|-|globalists want we
+cannot deal with our energy hunger, environmental issues, lack of natural
+resources, upcoming technologies without global cooperation. We currently see a
+regression in cooperation by nationalistic movements, protectionism and the usual
+going back to presumed better times, but that won't work.
+
+Local user groups are important but the number of members is not growing. There
+is some cooperation between groups but eventually we might need to combine the
+groups into one which might succeed unless one wants to come first. Of course we
+will get the same sentiments and arguments as in regular politics but on the
+other hand, we already have the advantage of \TEX\ systems being multi|-|lingual
+and users sharing interest in the diversity of usage and users. The biggest
+challenge is to pass on what we have achieved. We're just a momentary highlight
+and let's not try to embrace some \quotation {\TEX\ first} madness.

+\startsection[title=Sexes]
+
+Most species have two sexes but it is actually a continuum controlled by hormones
+and genetic expression: we just have to accept it. Although the situation has
+improved there are plenty of places where some gender relationships are
+considered bad even to the extent that one's life can be in danger. Actually
+having strong ideas about these issues is typically human. But in the end one has
+to accept the continuum.
+
+In a similar way we just have to accept that \TEX\ usage, application of \TEX\
+engines, etc.\ is a continuum and not a batch versus \WYSIWYG\ battle any more.
+It's disturbing to read strong recommendations not to use this or that. Of the
+many macro packages that showed up only a few were able to survive. How do users
+of outlines look at bitmaps, how do \DVI\ lovers look at \PDF. But, as
+typesetting relates to esthetics, strong opinions come with the game.
+
+Sapolsky reports about a group of baboons where due to the fact that they get the
+first choice of food the alpha males of pack got poisoned, so that the remaining
+suppressed males who treated the females well became dominant. In fact they can
+then make sure that no new alpha male from outside joins the pack without
+behaving like they do. A sort of social selection. In a similar fashion, until
+now the gatherings of \TEX ies managed to keep its social properties and has not
+been dominated by for instance commerce.
+
+% So, maybe should focus on acceptance and tolerance and then make sure that that
+% we keep what we have and let it not be influenced too much by sectarianism. It
+% makes a nice topic for a meeting of the context (sub)group, that actually has a
+% women as driving force. How can we preserve what we have but still proceed is a
+% legitimate question. Where do we stand in the landscape.
+
+In the animal world often sexes relate to appearance. The word sexy made it to
+other domains as well. Is \TEX\ sexy? For some it is. We often don't see the real
+colors of birds. What looks gray to us looks vivid to a bird which sees in a
+different spectrum. The same is true for \TEX. Some users see a command line
+(shell) and think: this is great! Others just see characters and keystrokes and
+are more attracted to an interactive program. When I see a graphic made by
+\METAPOST, I always note how exact it is. Others don't care if their interactive
+effort doesn't connect the dots well. Some people (also present here) think that
+we should make \TEX\ attractive but keep in mind that like and dislike are not
+fixed human properties. Some mindsets might as well be the result from our
+makeup, others can be driven by culture.

+
+\startsection[title=Religion]
+
+One of Sapolsky's lectures is about religion and it comes in the sequence of
+mental variations including depression and schizophrenia, because all these
+relate to mental states, emotions, thresholds and such (all things human). That
+makes it a tricky topic which is why it has not been taped. As I was raised in a
+moderate Protestant tradition I can imagine that it's an uncomfortable topic
+instead. But there are actually a few years older videos around and they are
+interesting to watch and not as threatening as some might expect. Here I just
+stick to some common characteristics.
+
+If you separate the functions that religions play into for instance explanation
+of the yet unknown, social interactions, control of power and regulation of
+morals, then it's clear why at \TEX\ user group meetings the religious aspect of
+\TEX\ has been discussed in talks. Those who see programs as infallible and
+always right and don't understand the inner working can see it as an almighty
+entity. In the Netherlands church-going diminishes but it looks like alternative
+meetings are replacing it (and I'm not talking of football matches). So what are
+our \TEX\ meetings? What do we believe in? The reason that I bring up this aspect
+is that in the \TEX\ community we can find aspects of the more extremist aspects
+of religions: if you don't use the macro package that I use, you're wrong. If you
+don't use the same operating system as I do, you're evil. You will be punished if
+you use the wrong editor for \TEX ? Why don't you use this library (which, by the
+way, just replaced that other one)? We create angels and daemons. Even for quite
+convinced atheists (it's not hard to run into them on youtube) a religion only
+survives when it has benefits, something that puzzles them. So when we're
+religious about \TEX\ and friends we have to make sure that it's at least
+beneficial. Also, maybe we fall in Dennett's category of \quotation {believers
+who want to believe}: it helps us to do our job if we just believe that we have
+the perfect tool. Religion has inspired visual and aural art and keeps doing
+that. (Don Knuth's current musical composition project is a good example of
+this.)
+
+Scientists can be religious, in flexible ways too, which is demonstrated by Don
+Knuth. In fact, I'm pretty sure \TEX\ would not be in the position it is in now
+if it weren't for his knowledgeable, inspirational, humorous, humble, and always
+positive presence. And for sure he's not at all religious about the open source
+software that he sent viral.
+
+I'm halfway through reading \quotation {The Good Book of Human Nature} (An
+Evolutionary Reading of the Bible) a book about the evolution of the bible and
+monotheism which is quite interesting. It discusses for instance how transitions
+from a hunter to a farmer society demanded a change of rules and introduced
+stories that made sense in that changing paradigm. Staying in one place means
+that possessions became more important and therefore inheritance. Often when
+religion is discussed by behavioral biologists, historians and anthropologists
+they stress this cultural narrative aspect. Also mentioned is that such societies
+were willing to support (in food and shelter) the ones that didn't normally fit
+it but added to the spiritual character of religions. The social and welcoming
+aspect is definitely present in for instance Bacho\TEX\ conferences although a
+bystander can wonder what these folks are doing in the middle of the night around
+a campfire, singing, drinking, frying sausages, spitting fire, and discussing the
+meaning of life.
+
+Those who wrap up the state of religious affairs, do predictions and advocate the
+message, are sometimes called evangelists. I remember a \TEX\ conference in the
+\USA\ where the gospel of \XML\ was preached (by someone from outside the \TEX\
+community). We were all invited to believe it. I was sitting in the back of the
+crowded (!)\ room and that speaker was not at all interested in who spoke before
+and after. Well, I do my share of \XML\ processing with \CONTEXT, but believe me:
+much of the \XML\ that we see is not according to any gospel. It's probably
+blessed the same way as those state officials get blessed when they ask and pray
+for it in public.
+
+It can get worse at \TEX\ conferences. Some present here at Bacho\TEX\ might
+remember the \PDF\ evangelists that we had show up at \TEX\ conferences. You see
+this qualification occasionally and I have become quite allergic to
+qualifications like architect, innovator, visionary, inspirator and evangelist,
+even worse when they look young but qualify as senior. I have no problem with
+religion at all but let's stay away from becoming one. And yes, typography also
+falls into that trap, so we have to be doubly careful.

+\startsection[title=Chaotic solutions]
+
+The lectures on \quotation {chaos and reductionism} and \quotation {emergence and
+complexity} were the highlights in Sapolsky's lectures. I'm not a good narrator
+so I will not summarize them but it sort of boils down to the fact that certain
+classes of problems cannot be split up in smaller tasks that we understand well,
+after which we can reassemble the solutions to deal with the complex task.
+Emerging systems can however cook up working solutions from random events.
+Examples are colonies of ants and bees.
+
+The \TEX\ community is like a colony: we cook up solutions, often by trial and
+error. We dream of the perfect solutions but deep down know that esthetics cannot
+be programmed in detail. This is a good thing because it doesn't render us
+obsolete. At last year's Bacho\TEX, my nephew Teun and I challenged the anthill
+outside the canteen to typeset the \TEX\ logo with sticks but it didn't persist.
+So we don't need to worry about competition from that end. How do you program a
+hive mind anyway?
+
+When chaos theory evolved in the second half of the previous century not every
+scientist felt happy about it. Instead of converging to more perfect predictions
+and control in some fields a persistent uncertainty became reality.
+
+After about a decade of using \TEX\ and writing macros to solve recurring
+situations I came to the conclusion that striving for a perfect \TEX\ (the
+engine) that can do everything and anything makes no sense. Don Knuth not only
+stopped adding code when he could do what he needed for his books, he also stuck
+to what to me seems reasonable endpoints. Every hard|-|coded solution beyond that
+is just that: a hard|-|coded solution that is not able to deal with the
+exceptions that make up most of the more complex documents. Of course we can
+theorize and discuss at length the perfect never|-|reachable solutions but
+sometimes it makes more sense to admit that an able user of a desktop publishing
+system can do that job in minutes, just by looking at the result and moving
+around an image or piece of text a bit.
+
+There are some hard|-|coded solutions and presets in the programs but with
+\LUATEX\ and \MPLIB\ we try to open those up. And that's about it. Thinking that
+for instance adding features like protrusion or expansion (or whatever else)
+always lead to better results is just a dream. Just as a butterfly flapping its
+wings on one side of the world can have an effect on the other side, so can
+adding a single syllable to your source completely confuse an otherwise clever
+column or page break algorithm. So, we settle for not adding more to the engine,
+and provide just a flexible framework.
+
+A curious observation is that when Edward Lorenz ran into chaotic models it was
+partially due to a restart of a simulation midway, using printed floating point
+numbers that then in the computer were represented with a different accuracy than
+printed. Aware of floating point numbers being represented differently across
+architectures, Don Knuth made sure that \TEX\ was insensitive to this so that its
+outcome was predictable, if you knew how it worked internally. Maybe \LUATEX\
+introduces a bit of chaos because the \LUA\ we use has only floats. In fact, a
+few months ago we did uncover a bug in the backend where the same phenomena gave
+a chaotic crash.
+
+In chaos theory there is the concept of an attractor. When visualized this can be
+the area (seemingly random) covered by a trajectory. Or it can be a single point
+where for instance a pendulum comes to rest. So what is our attractor? We have a
+few actually. First there is the engine, the stable core of primitives always
+present. You often see programs grow more complex every update and for sure that
+happened with \ETEX, \PDFTEX, \XETEX\ and \LUATEX. However there is always the
+core that is supposed to be stable. After some time the new kid arrives at a
+stable state not much different from the parent. The same is true for \METAPOST.
+Fonts are somewhat different because the technology changes but in the end the
+shapes and their interactions become stable as well. Yet another example is \TEX\
+Live: during a year it might diverge from its route but eventually it settles
+down and enters the area where we expect it to end up. The \TEX\ world is at
+times chaotic, but stable in the long run.
+
+So, how about the existence, the reason for it still being around? One can
+speculate about its future trajectory but one thing is sure: as long as we break
+a text into paragraphs and pages \TEX\ is hard to beat. But what if we don't need
+that any more? What if the concept of a page is no longer relevant? What if
+justified texts no longer matter (often designers don't care anyway)? What if
+students are no longer challenged to come up with a nice looking thesis? Do these
+collaborative tools with remote \TEX\ processing really bring new long term users
+or is \TEX\ then just one of the come|-|and|-|go tools?
+
+\stopsection
+
+\startsection[title=Looking ahead]
+
+In an interview (\quotation {World of ideas}) Asimov explains that science
+fiction evolved rapidly when people lived long enough to see that there was a
+future (even for their offspring) that is different from today. It is (at least
+for me) mind boggling to think of an evolution of hundreds of thousands of years
+to achieve something like language. Waiting for the physical being to arrive at a
+spot where you can make sounds, where the brain is suitable for linguistic
+patterns, etc. A few hundred years ago speed of any developments (and science)
+stepped up.
+
+\TEX\ is getting near 40 years old. Now, for software that {\bf is} old! In that
+period we have seen computers evolve: thousands of times faster processing, even
+more increase in memory and storage. If we read about spaceships that travel at a
+reasonable fraction of the speed of light, and think that will not happen soon,
+just think back to the terminals that were sitting in computer labs when \TEX\
+was developed: 300 baud was normal. I actually spent quite some time on
+optimizing time|-|critical components of \CONTEXT\ but on this timescale that is
+really a waste of time. But even temporary bottlenecks can be annoying (and
+costly) enough to trigger such an effort. (Okay, I admit that it can be a
+challenge, a kind of game, too.)
+
+Neil Tyson, in the video \quotation {Storytelling of science} says that when
+science made it possible to make photos it also made possible a transition in
+painting to impressionism. Other technology could make the exact snapshot so
+there was new room for inner feelings and impressions. When the Internet showed
+up we went through a similar transition, but \TEX\ actually dates from before the
+Internet. Did we also have a shift in typesetting? To some extent yes, browsers
+and real time rendering is different from rendering pages on paper. In what space
+and time are \TEX ies rooted?
+
+We get older than previous generations. Quoting Sapolsky \quotation{\unknown\ we
+are now living well enough and long enough to slowly fall apart.} The opposite is
+happening with our tools, especially software: it's useful lifetime becomes
+shorter and changes faster each year. Just look at the version numbers of
+operating systems. Don Knuth expected \TEX\ to last for a long time and compared
+to other software its core concept and implementation is doing surprisingly well.
+We use a tool that suits our lifespan! Let's not stress ourselves out too much
+with complex themes. (It helps to read \quotation {Why zebras don't get ulcers}.)
+
+\stopsection
+
+\startsection[title=Memes]
+
+If you repeat a message often enough, even if it's something not true, it can
+become a meme that gets itself transferred across generations. Conferences like
+this is where they can evolve. We tell ourselves and the audience how good \TEX\
+is and because we spend so many hours, days, weeks, months using it, it actually
+must be good, or otherwise we would not come here and talk about it. We're not so
+stupid as to spend time on something not good, are we? We're always surprised
+when we run into a (potential) customer who seems to know \TEX. It rings a bell,
+and it being around must mean something. Somehow the \TEX\ meme has anchored
+itself when someone attended university. Even if experiences might have been bad
+or usage was minimal. The meme that \TEX\ is the best in math typesetting is a
+strong survivor.
+
+There's a certain kind of person who tries to get away with their own deeds and
+decisions by pointing to \quotation {fake news} and accusations of \quotation
+{mainstream media} cheating on them. But to what extent are our stories true
+about how easy \TEX\ macro packages are to use and how good their result? We have
+to make sure we spread the right memes. And the user groups are the guardians.
+
+Maybe macro packages are like memes too. In the beginning there was a bunch but
+only some survived. It's about adaptation and evolution. Maybe competition was
+too fierce in the beginning. Like ecosystems, organisms and cellular processes in
+biology we can see the \TEX\ ecosystem, users and usage, as a chaotic system.
+Solutions pop up, succeed, survive, lead to new ones. Some look similar and
+slightly different input can give hugely different outcomes. You cannot really
+look too far ahead and you cannot deduce the past from the present. Whenever
+something kicks it off its stable course, like the arrival of color, graphics,
+font technologies, \PDF, \XML, ebooks, the \TEX\ ecosystem has to adapt and find
+its stable state again. The core technology has proven to be quite fit for the
+kind of adaptation needed. But still, do it wrong and you get amplified out of
+existence, don't do anything and the external factors also make you extinct.
+There is no denial that (in the computer domain) \TEX\ is surprisingly stable and
+adaptive. It's also hard not to see how conservatism can lead to extinction.

+\startsection[title=Inspiration]
+
+I just took some ideas from different fields. I could have mentioned quantum
+biology, which tries to explain some unexplainable phenomena in living creatures.
+For instance how do birds navigate without visible and measurable clues. How do
+people arrive at \TEX\ while we don't really advertise? Or I could mention
+epigenetics and explorations in junk \DNA. It's not the bit of the genome that we
+thought that matters, but also the expression of the genes driven by other
+factors. Offspring not only gets genetic material passed but it can get presets.
+How can the \TEX\ community pass on Knuth's legacy? Do we need to hide the
+message in subtle ways? Or how about the quest for dark matter? Does it really
+exist or do we want (need) it to exist? Does \TEX\ really have that many users,
+or do we cheat by adding the users that are enforced during college but don't
+like it at all? There's enough inspiration for topics at \TEX\ conferences, we
+just have to look around us.
+
+\stopsection
+
+\startsection[title=Stability]
+
+I didn't go into technical aspects of \TEX\ yet. I must admit that after decades
+of writing macros I've reached a point where I can safely say that there will
+never be perfect automated solutions for really complex documents. When books
+about neural networks show up I wondered if it could be applied (but I couldn't).
+When I ran into genetic algorithms I tried to understand its possible impact (but
+I never did). So I stuck to writing solutions for problems using visualization:
+the trial and error way. Of course, speaking of \CONTEXT, I will adapt what is
+needed, and others can do that as well. Is there a new font technology? Fine,
+let's support it as it's no big deal, just a boring programming task. Does a user
+want a new mechanism? No problem, as solving a reduced subset of problems can be
+fun. But to think of \TEX\ in a reductionist way, i.e.\ solving the small
+puzzles, and to expect the whole to work in tandem to solve a complex task is not
+trivial and maybe even impossible. It's a good thing actually, as it keeps us on
+edge. Also, \CONTEXT\ was designed to help you with your own solutions: be
+creative.
+
+I mentioned my nephew Bram. He has seen part of this crowd a few times, just like
+his brother and sister do now. He's into artificial intelligence now. In a few
+years I'll ask him how he sees the current state of \TEX\ affairs. I might learn
+a few tricks in the process.
+
+In \quotation {The world without us} Weisman explores how fast the world would be
+void of traces of humankind. A mere 10.000 years can be more than enough. Looking
+back, that's about the time hunters became farmers. So here's a challenge: say
+that we want an ant culture that evolves to the level of having archaeologists to
+know that we were here at Bacho\TEX\ \unknown\ what would we leave behind?
+
+Sapolsky ends his series by stressing that we should accept and embrace
+individual differences. The person sitting next to you can have the same makeup
+but be just a bit more sensitive to depression or be the few percent with genes
+controlling schizophrenic behaviour. He stresses that knowing how things work or
+where things go wrong doesn't mean that we should fix everything. So look at this
+room full of \TEX ies: we don't need to be all the same, use all the same, we
+don't need some dominance, we just need to accept and especially we need to
+understand that we can never fully understand (and solve) everything forever.
+
+Predictions, one of the themes, can be hard. It's not true that science has the
+answer to everything. There will always be room for speculation and maybe we will
+always need metaphysics too. I just started to read \quotation {What we cannot
+know} by Sautoy. For sure those present here can not predict how \TEX\ will go on
+and|/|or be remembered.
+
+\stopsection
+
+\startsection[title=Children of \TEX]
+
+I mentioned \quotation {Children of time}. The author lets you see their spidery
+world through spider eyes and physiology. They have different possibilities
+(eyesight, smell) than we do and also different mental capabilities. They evolve
+rapidly and have to cope conceptually with signals from a human surveillance
+satellite up in the sky. Eventually they need to deal with a bunch of (of course)
+quarrelling humans who want their place on the planet. We humans have some
+pre|-|occupation with spiders and other creatures. In a competitive world it is
+sometimes better to be suspicious (and avoid and flee) that to take a risk of
+being eaten. A frequently used example is that a rustle in a bush can be the wind
+or a lion, so best is to run.
+
+We are not that well adapted to our current environment. We evolved at a very
+slow pace so there was no need to look ahead more than a year. And so we still
+don't look too far ahead (and choose politicians accordingly). We can also not
+deal that well with statistics (Dawkins's \quotation {Climbing Mount Probability}
+is a good read) so we make false assumptions, or just forget.
+
+Does our typeset text really look that good on the long run, or do we cheat with
+statistics? It's not too hard to find a bad example of something not made by
+\TEX\ and extrapolate that to the whole body of typeset documents. Just like we
+can take a nice example of something done by \TEX\ and assume that what we do
+ourselves is equally okay. I still remember the tests we did with \PDFTEX\ and
+hz. When \THANH\ and I discussed that with Hermann Zapf he was not surprised at
+all that no one saw a difference between the samples and instead was focusing on
+aspects that \TEX ies are told to look at, like two hyphens in a row.
+
+A tool like \TEX\ has a learning curve. If you don't like that just don't use it.
+If you think that someone doesn't like that, don't enforce this tool on that
+someone. And don't use (or lie with) statistics. Much better arguments are that
+it's a long|-|lived stable tool with a large user base and support. That it's not
+a waste of time. Watching a designer like Hermann Zapf draw shapes is more fun
+than watching click and point in heavily automated tools. It's probably also less
+fun to watch a \TEX ie converge towards a solution.
+
+Spiders are resilient. Ants maybe even more. Ants will survive a nuclear blast
+(mutations might even bring them benefits), they can handle the impact of a
+meteorite, a change in climate won't harm them much. Their biggest enemy is
+probably us, when we try to wipe them out with poison. But, as long as they keep
+a low profile they're okay. \TEX\ doesn't fit into the economic model as there is
+no turnaround involved, no paid development, it is often not seen at all, it's
+just a hit in a search engine and even then you might miss it (if only because no
+one pays for it being shown at the top).
+
+We can learn from that. Keeping a low profile doesn't trigger the competition to
+wipe you out. Many (open source) software projects fade away: some big company
+buys out the developer and stalls the project or wraps what they bought in their
+own stuff, other projects go professional and enterprise and alienate the
+original users. Yet others abort because the authors lose interest. Just like the
+ideals of socialism don't automatically mean that every attempt to implement it
+is a success, so not all open source and free software is good (natured) by
+principle either. The fact that communism failed doesn't mean that capitalism is
+better and a long term winner. The same applies to programs, whether successful
+or not.
+
+Maybe we should be like the sheep. Dennett uses these animals as a clever
+species. They found a way to survive by letting themselves (unconsciously) be
+domesticated. The shepherd guarantees food, shelter and protection. He makes sure
+they don't get ill. Speaking biologically: they definitely made sure that many
+copies of their genes survived. Cows did the same and surprisingly many of them
+are related due to the fact that they share the same father (something now trying
+to be reverted). All \TEX\ spin|-|offs relate to the same parent, and those that
+survived are those that were herded by user groups. We see bits and pieces of
+\TEX\ end up in other applications. Hyphenation is one of them. Maybe we should
+settle for that small victory in a future hall of fame.
+
+When I sit on my balcony and look at the fruit trees in my garden, some simple
+math can be applied. Say that one of the apple trees has 100 apples per year and
+say that this tree survives for 25 years (it's one of those small manipulated
+trees). That makes 2.500 apples. Without human intervention only a few of these
+apples make it into new trees, otherwise the whole world would be dominated by
+apple trees. Of course that tree now only survives because we permit it to
+survive, and for that it has to be humble (something that is very hard for modern
+Apples). Anyway, the apple tree doesn't look too unhappy.
+
+A similar calculation can be done for birds that nest in the trees and under my
+roof. Given that the number of birds stays the same, most of energy spent on
+raising offspring is wasted. Nevertheless they seem to enjoy life. Maybe we
+should be content if we get one enthusiastic new user when we demonstrate \TEX\
+to thousands of potential users.
+
+Maybe, coming back to the themes of the conference, we should not come up with
+these kinds of themes. We seem to be quite happy here. Talking about the things
+that we like, meeting people. We just have to make sure that we survive. Why not
+stay low under the radar? That way nothing will see us as a danger. Let's be like
+the ants and spiders, the invisible hive mind that carries our message, whatever
+that is.
+
+When Dennett discusses language he mentions (coined) words that survive in
+language. He also mentions that children pick up language no matter what. Their
+minds are made for it. Other animals don't do that: they listen but don't start
+talking back. Maybe \TEX\ is just made for certain minds. Some like it and pick
+it up, while for others it's just noise. There's nothing wrong with that.
+Predilection can be a user property.

+\startsection[title={The unexpected}]
+
+In a discussion with Dawkins the well|-|spoken astrophysicist Neil deGrasse Tyson
+brings up the following. We differ only a few percent in \DNA\ from a chimp but
+quite a lot in brain power, so how would it be if an alien that differs a few
+percent (or more) passes by earth. Just like we don't talk to ants or chimps or
+whatever expecting an intelligent answer, whatever passes earth won't bother
+wasting time on us. Our rambling about the quality of typesetting probably sounds
+alien to many people who just want to read and who happily reflow a text on an
+ebook device, not bothered by a lack of quality.

+
+We tend to take ourselves as reference. In \quotation {Rare Earth} Ward and
+Brownlee extrapolate the possibility of life elsewhere in the universe. They are
+not alone in thinking that while on one hand applying statistics to these
+formulas of possible life on planets there might also be a chance that we're the
+only intelligent species ever evolved. In a follow up, \quotation {Life as we do
+not know it} paleontologist and astrobiologist Ward (one of my favourite authors)
+discusses the possibility of life not based on carbon, which is not natural for a
+carbon based species. Carl Sagan once pointed out that an alien species looking
+down to earth can easily conclude that cars are the dominant species on earth and
+that the thingies crawling in and out them are some kind of parasites. So, when
+we look at the things that somehow end up on paper (as words, sentences,
+ornaments, etc.), what is dominant there? And is what we consider dominant really
+that dominant in the long run? You can look at a nice page as a whole and don't
+see the details of the content. Maybe beauty hides nonsense.
+
+When \TEX ies look around they look to similar technologies. Commands in shells
+and solutions done by scripting and programming. This make sense in the
+perspective of survival. However, if you want to ponder alternatives, maybe not
+for usage but just for fun, a completely different perspective might be needed.
+You must be willing to accept that communicating with a user of a \WYSIWYG\
+program might be impossible. If mutual puzzlement is a fact, then they can either
+be too smart and you can be too dumb or the reverse. Or both approaches can be
+just too alien, based on different technologies and assumptions. Just try to
+explain \TEX\ to a kid 40 years younger or to an 80 year old grandparent for that
+matter. Today you can be very clever in one area and very stupid in another.
+
+In another debate, Neil deGrasse Tyson asks Dawkins the question why in science
+fiction movies the aliens look so human and when they don't, why they look so
+strange, for instance like cumbersome sluggish snails. The response to that is
+one of puzzlement: the opponent has no reference of such movies. In discussions
+old \TEX ies like to suggest that we should convert young users. They often don't
+understand that kids live in a different universe.
+
+How often does that happen to us? In a world of many billions \TEX\ has its place
+and can happily coexist with other typesetting technologies. Users of other
+technologies can be unaware of us and even create wrong images. In fact, this
+also happens in the community itself: (false) assumptions turned into
+conclusions. Solutions that look alien, weird and wrong to users of the same
+community. Maybe something that I present as hip and modern and high|-|\TEX\ and
+promising might be the opposite: backward, old|-|fashioned and of no use to
+others. Or maybe it is, but the audience is in a different mindset. Does it
+matter? Let's just celebrate that diversity. (So maybe, instead of discussing the
+conference theme, I should have talked about how I abuse \LUATEX\ in controlling
+lights in my home as part of some IoT experiments.)

+\startsection[title=What drives us]
+
+I'm no fan of economics and big money talk makes me suspicious. I cannot imagine
+working in a large company where money is the drive. It also means that I have
+not much imagination in that area. We get those calls at the office from far away
+countries who are hired to convince us by phone of investments. Unfortunately
+mentioning that you're not at all interested in investments or that multiplying
+money is irrelevant to you does not silence the line. You have to actively kill
+such calls. This is also why I probably don't understand today's publishing world
+where money also dominates. Recently I ran into talks by Mark Blyth about the
+crisis (what crisis?) and I wish I could argue like he does when it comes to
+typesetting and workflows. He discusses quite well that most politicians have no
+clue what the crisis is about.
+
+I think that the same applies to the management of publishers: many have no clue
+what typesetting is about. So they just throw lots of money into the wrong
+activities, just like the central banks seem to do. It doesn't matter if we \TEX
+ies demonstrate cheap and efficient solutions.
+
+Of course there are exceptions. We're lucky to have some customers that do
+understand the issues at hand. Those are also the customers where authors may use
+the tools themselves. Educating publishers, and explaining that authors can do a
+lot, might be a premise, predilection and prediction in one go! Forget about
+those who don't get it: they will lose eventually, unfortunately not before they
+have reaped and wasted the landscape.
+
+Google, Facebook, Amazon, Microsoft and others invest a lot in artificial
+intelligence (or, having all that virtual cash, just buy other companies that
+do). They already have such entities in place to analyze whatever you do. It is
+predicted that at some point they know more about you then you know yourself.
+Reading Luke Dormehl's \quotation {The Formula} is revealing. So what will that
+do with our so|-|called (disputed by some) free will? Can we choose our own
+tools? What if a potential user is told that all his or her friends use
+WhateverOffice so they'd better do that too? Will subtle pressure lead them or
+even us users away from \TEX ? We already see arguments among \TEX ies, like
+\quotation {It doesn't look updated in 3 years, is it still good?} Why update
+something that is still valid? Will the community be forced to update everything,
+sort of fake updates. Who sets out the rules? Do I really need to update (or
+re|-|run) manuals every five years?
+
+Occasionally I visit the Festo website. This is a (family owned) company that
+does research at the level that used to be common in large companies decades ago.
+If I had to choose a job, that would be the place to go to. Just google for
+\quotation {festo bionic learning network} and you understand why. We lack this
+kind of research in the field we talk about today: research not driven by
+commerce, short term profit, long term control, but because it is fundamental
+fun.
+
+Last year Alan Braslau and I spent some time on \BIBTEX. Apart from dealing with
+all the weird aspects of the \APA\ standard, dealing with the inconsistently
+constructed author fields is a real pain. There have been numerous talks about
+that aspect here at Bacho\TEX\ by Jean|-|Michel Hufflen. We're trying to deal
+with a more than 30|-|year|-|old flawed architecture. Just look back over a curve
+that backtracks 30 years of exponential development in software and databases and
+you realize that it's a real waste of time and a lost battle. It's fine to have a
+text based database, and stable formats are great, but the lack of structure is
+appalling and hard to explain to young programmers. Compare that to the Festo
+projects and you realize that there can be more challenging projects. Of course,
+dealing with the old data can be a challenge, a necessity and eventually even be
+fun, but don't even think that it can be presented as something hip and modern.
+We should be willing to admit flaws. No wonder that Jean|-|Michel decided to
+switch to talking about music instead. Way more fun.
+
+Our brains are massively parallel bio|-|machinery. Groups of neurons cooperate
+and compete for attention. Coming up with solutions that match what comes out of
+our minds demands a different approach. Here we still think in traditional
+programming solutions. Will new ideas about presenting information, the follow up
+on books come from this community? Are we the innovative Festo or are we an old
+dinosaur that just follows the fashion?
+
+\stopsection
+
+\startsection[title=User experience]
+
+Here is a nice one. Harari spends many pages explaining that research shows that
+when an unpleasant experience has less unpleasantness at the end of the period
+involved, the overall experience is valued according to the last experience. Now,
+this is something we can apply to working with \TEX: often, the more you reach
+the final state of typesetting the more it feels as all hurdles are in the
+beginning: initial coding, setting up a layout, figuring things out, etc.
+
+It can only get worse if you have a few left|-|over typesetting disasters but
+there adapting the text can help out. Of course seeing it in a cheap bad print
+can make the whole experience bad again. It happens. There is a catch here: one
+can find lots of bad|-|looking documents typeset by \TEX. Maybe there frustration
+(or indifference) prevails.
+
+I sometimes get to see what kind of documents people make with \CONTEXT\ and it's
+nice to see a good looking thesis with diverse topics: science, philosophy,
+music, etc. Here \TEX\ is just instrumental, as what it is used for is way more
+interesting (and often also more complex) than the tool used to get it on paper.
+We have conferences but they're not about rocket science or particle
+accelerators. Proceedings of such conferences can still scream \TEX, but it's the
+content that matters. Here somehow \TEX\ still sells itself, being silently
+present in rendering and presentations. It's like a rootkit: not really
+appreciated and hard to get rid of. Does one discuss the future of rootkits other
+than in the perspective of extinction? So, even as an invisible rootkit, hidden
+in the workings of other programs, \TEX's future is not safe. Sometimes, when you
+install a Linux system, you automatically get this large \TEX\ installation,
+either because of dependencies or because it is seen as a similar toolkit as for
+instance Open (or is it Libre) Office. If you don't need it, that user might as
+well start seeing it as a (friendly) virus.
+
+\stopsection
+
+\startsection[title=Conclusion]
+
+At some point those who introduced computers in typesetting had no problem
+throwing printing presses out of the window. So don't pity yourself if at some
+point in the near future you figure out that professional typesetting is no
+longer needed. Maybe once we let machines rule the world (even more) we will be
+left alone and can make beautiful documents (or whatever) just for the joy, not
+bothering if we use outdated tools. After all, we play modern music on old
+instruments (and the older rock musicians get, the more they seem to like
+acoustic).
+
+There are now computer generated compositions that experienced listeners cannot
+distinguish from old school. We already had copies of paintings that could only
+be determined forgeries by looking at chemical properties. Both of these
+(artificial) arts can be admired and bring joy. So, the same applies to fully
+automated typeset novels (or runtime rendered ebooks). How bad is that really?
+You don't dig channels with your hand. You don't calculate logarithmic tables
+manually any longer.
+
+However, one of the benefits of the Internet is watching and listening to great
+minds. Another is seeing musicians perform, which is way more fun that watching a
+computer (although googling for \quotation {animusic} brings nice visuals).
+Recently I ran into a wooden musical computer made by \quotation {Wintergatan}
+which reminded me of the \quotation {Paige Compositor} that we use in a \LUATEX\
+cartoon. Watching something like that nicely compensates for a day of rather
+boring programming. Watching how the marble machine x (mmx) evolves is yet
+another nice distraction.
+
+Now, the average age of the audience here is pretty high even if we consider that
+we get older. When I see solutions of \CONTEXT\ users (or experts) posted by
+(young) users on the mailing list or stack exchange I often have to smile because
+my answer would have been worse. A programmable system invokes creative
+solutions. My criterion is always that it has to look nice in code and has some
+elegance. Many posted solutions fit. Do we really want more automation? It's more
+fun to admire the art of solutions and I'm amazed how well users use the
+possibilities (even ones that I already forgot).
+
+One of my favourite artists on my weekly \quotation {check youtube} list is Jacob
+Collier. Right from when I ran into him I realized that a new era in music had
+begun. Just google for his name and \quotation {music theory interview} and you
+probably understand what I mean. When Dennett comments on the next generation
+(say up to 25) he wonders how they will evolve as they grow up in a completely
+different environment of connectivity. I can see that when I watch family
+members. Already long ago Greg Bear wrote the novel \quotation {Darwin's
+Children}. It sets you thinking and when looking around you even wonder if there
+is a truth in it.
+
+There are folks here at Bacho\TEX\ who make music. Now imagine that this is a
+conference about music and that the theme includes the word \quotation {future}.
+Then, imagine watching that video. You see some young musicians, one of them
+probably one of the musical masterminds of this century, others instrumental to
+his success, for instance by wrapping up his work. While listening you realize
+that this next generation knows perfectly well what previous generations did and
+achieved and how they influenced the current. You see the future there. Just look
+at how old musicians reflect on such videos. (There are lots of examples of youth
+evolving into prominent musicians around and I love watching them). There is no
+need to discuss the future, in fact, we might make a fool of ourselves doing so.
+Now back to this conference. Do we really want to discuss the future? What we
+think is the future? Our future? Why not just hope that in the flow of getting
+words on a medium we play our humble role and hope we're not forgotten but
+remembered as inspiration.
+
+One more word about predicting the future. When Arthur Clarke's \quotation {2001:
+A Space Odyssey} was turned into a movie in 1968, a lot of effort went into
+making sure that the not so far ahead future would look right. In 1996 scientists
+were asked to reflect on these predictions in \quotation {Hal's Legacy}. It
+turned out that most predictions were plain wrong. For instance computers got way
+smaller (and even smaller in the next 20 years) while (self|-|aware) artificial
+intelligence had not arrived either. So, let's be careful in what we predict (and
+wish for).
+
+\stopsection
+
+\startsection[title=No more themes]
+
+We're having fun here, that's why we come to Bacho\TEX\ (predilection). That
+should be our focus. Making sure that \TEX's future is not so much in the cutting
+edge but in providing fun to its users (prediction). So we just have to make sure
+it stays around (premise). That's how it started out. Just watch at Don Knuth's
+3:16 poster: via \TEX\ and \METAFONT\ he got in contact with designers and I
+wouldn't be surprised if that sub|-|project was among the most satisfying parts.
+So, maybe instead of ambitious themes the only theme that matters is: show what
+you did and how you did it.

+
+This is a collection of articles and wrap|-|ups that don't suit in other manuals
+or collections. Some are published, some meant as draft for a presentation.
+
+The \quotation {Children of \TEX} article is the framework for a presentation at
+Bacho\TEX\ 2017 in Poland, and covers the main theme of the conference. In the
+aftermath of that conference I wrote \quotation {Advertising \TEX} and later
+\quotation {Why use \TEX?}. The 2018 Bacho\TEX\ conference theme is explored in
+\quotation {What’s to stay, what’s to go}. After a short discussion on the
+\CONTEXT\ mailing list about stability (at the moment that \MKII\ had been frozen
+for more than a decade but is still used without problems) I wrote \quotation
+{Stability}.
+
+Many of the thoughts in these articles are influenced by discussions with my
+colleagues Ton Otten and Kees van Marle. Operating in a similar arena, they
+provide me the reflection needed to sort out my thoughts on these matters.

+\startchapter[title=Advertising \TEX]
+
+I can get upset when I hear \TEX ies boast about the virtues of \TEX\ compared to
+for instance Microsoft Word. Not that I feel responsible for defending a program
+that I never use(d) but attacking something for no good reason makes not much
+sense to me. It is especially annoying when the attack is accompanied by a
+presentation that looks pretty bad in design and typography. The best
+advertisements for \TEX\ should of course come from outside the \TEX\ community,
+by people impressed by its capabilities. How many \TEX ies can really claim that
+Word is bad when they never tried to make something in it with a similar learning
+curve as they had in \TEX\ or the same amount of energy spent in editing and
+perfecting a word|-|processor|-|made document.
+
+In movies where computer technology plays a role one can encounter weird
+assumptions about what computers and programs can do. Run into a server room,
+pull one disk out of a \RAID-5 array and get all information from it. Connect
+some magic device to a usb port of a phone and copy all data from it in seconds.
+Run a high speed picture or fingerprint scan on a computer (probably on a remote
+machine) and show all pictures flying by. Okay, it's not so far from other
+unrealistic aspects in movies, like talking animals, so maybe it is just a
+metaphor for complexity and speed. When zapping channels on my television I saw
+\in{figure}[fig:tex-in-movie] and as the media box permits replay I could make a
+picture. I have no clue what the movie was about or what movie it was so a
+reference is lacking here. Anyway it's interesting that seeing a lot of \TEX\
+code flying by can impress someone: the viewer, even if no \TEX ie will ever see
+that on the console unless in some error or tracing message and even then it's
+hard to get that amount. So, the viewer will never realize that what is seen is
+definitely not what a \TEX ie wants to see.
+
+\startplacefigure[title={\TEX\ in a movie},reference=fig:tex-in-movie]
+    \externalfigure[tex-in-movie.jpg][height=8cm]
+\stopplacefigure
+
+So, as that kind of free advertisement doesn't promote \TEX\ well, what of an
+occasional mentioning of \TEX\ in highly|-|regarded literature? When reading
+\quotation {From bacteria to Bach and back, the evolution of minds} by Daniel
+Dennett I ran into the following:
+
+\startquotation
+In Microsoft Word, for instance, there are the typographical operations of
+superscript and subscript, as illustrated by
+
+\startnarrower
+base\high{power}
+\stopnarrower
+
+and
+
+\startnarrower
+human\low{female}
+\stopnarrower
+
+But try to add another superscript to base\high{power}\emdash it {\em should}
+work, but it doesn't! In mathematics, you can raise powers to powers to powers
+forever, but you can't get Microsoft Word to display these (there are other
+text|-|editing systems, such as TeX, that can). Now, are we sure that human
+languages make use of true recursion, or might some or all of them be more like
+Microsoft Word? Might our interpretation of grammars as recursive be rather an
+elegant mathematical idealization of the actual \quotation {moving parts} of a
+grammar?
+\stopquotation
+
+Now, that book is a wonderfully interesting read and the author often refers to
+other sources. When one reads some reference (with a quote) then one assumes that
+what one reads is correct, and I have no reason to doubt Dennett in this. But
+this remark about \TEX\ has some curious inaccuracies. \footnote {Of course one
+can wonder in general that when one encounters such an inaccuracy, how valid
+other examples and conclusions are. However, consistency in arguments and
+confirmation by other sources can help to counter this.}
+
+First of all a textual raise or lower is normally not meant to be recursive.
+Nesting would have interesting consequences for the interline space so one will
+avoid it whenever possible. There are fonts that have superscript and subscript
+glyphs and even \UNICODE\ has slots for a bunch of characters. I'm not sure what
+Word does: take the special glyph or use a scaled down copy?
+
+Then there is the reference to \TEX\ where we can accept that the \quotation {E}
+is not lowered but just kept as a regular \quotation {e}. Actually the mentioning
+of nested scripts refers to typesetting math and that's what the superscripts and
+subscripts are for in \TEX. In math mode however, one will normally raise or
+lower symbols and numbers, not words: that happens in text mode.
+
+While Word will use the regular text font when scripting in text mode, a \TEX\
+user will either have to use a macro to make sure that the right size (and font)
+is used, or one can revert to math mode. But how to explain that one has to enter
+math and then explicitly choose the right font? Think of this:
+
+\startbuffer
+efficient\high{efficient} or
+efficient$^{\text{efficient}}$ or \par
+{\bf efficient\high{efficient} or
+efficient$^{\text{efficient}}$}
+\stopbuffer
+
+\typebuffer
+
+Which gives (in Cambria)
+
+\getbuffer
+
+Now this,
+
+\startbuffer
+efficient\high{efficient\high{efficient}} or
+efficient$^{\text{efficient$^{\text{efficient}}$}}$ or \par
+{\bf efficient\high{efficient\high{efficient}} or
+efficient$^{\text{efficient$^{\text{efficient}}$}}$}
+\stopbuffer
+
+\typebuffer
+
+will work okay but the math variant is probably quite frightening at a glance for
+an average Word user (or beginner in \TEX) and I can understand why someone would
+rather stick to click and point.
+
+\getbuffer
+
+Oh, and it's tempting to try the following:
+
+\startbuffer
+efficient{\addff{f:superiors}efficient}
+\stopbuffer
+
+\typebuffer
+
+but that only works with fonts that have such a feature, like Cambria:
+
+\blank {\switchtobodyfont[cambria]\getbuffer} \blank
+
+To come back to Dennett's remark: when typesetting math in Word, one just has to
+switch to the math editing mode and one can have nested scripts! And, when using
+\TEX\ one should not use math mode for text scripts. So in the end in both
+systems one has to know what one is doing, and both systems are equally capable.
+
+The recursion example is needed in order to explain how (following recent ideas
+from Chomsky) for modern humans some recursive mechanism is needed in our
+wetware. Now, I won't go into details about that (as I can only mess up an
+excellent explanation) but if you want to refer to \TEX\ in some way, then
+expansion \footnote{Expanding macros actually works well with tail recursion.} of
+(either combined or not) snippets of knowledge might be a more interesting model
+than recursion, because much of what \TEX\ is capable of relates to expansion.
+But I leave that to others to explore. \footnote {One quickly starts thinking of
+how \cs {expandafter}, \type {noexpand}, \type {unexpanded}, \type {protected}
+and other primitives can be applied to language, understanding and also
+misunderstanding.}
+
+Now, comparing \TEX\ to Word is always kind of tricky: Word is a text editor with
+typesetting capabilities and \TEX\ is a typesetting engine with programming
+capabilities. Recursion is not really that relevant in this perspective. Endless
+recursion in scripts makes little sense and even \TEX\ has its limits there: the
+\TEX\ math engine only distinguishes three levels (text, script and scriptscript)
+and sometimes I'd like to have a level more. Deeper nesting is just more of
+scriptscript unless one explicitly enforces some style. So, it's recursive in the
+sense that there can be many levels, but it also sort of freezes at level three.
+
+\startplacefigure[title={Nicer than \TEX},reference=fig:nicer-than-tex]
+    \externalfigure[mathematics.png][width=\textwidth]
+\stopplacefigure
+
+I love \TEX\ and I like what you can do with it and it keeps surprising me. And
+although mathematics is part of that, I seldom have to typeset math myself. So, I
+can't help that \in {figure} [fig:nicer-than-tex] impresses me more. It even has
+the so|-|familiar|-|to|-|\TEX ies dollar symbols in it: the poem \quotation
+{Poetry versus Orchestra} written by Hollie McNish, music composed by Jules
+Buckley and artwork by Martin Pyper (I have the \DVD\ but you can also find it on
+\YOUTUBE). It reminds me of Don Knuth's talk at a \TUG\ meeting. In \TUGBOAT\
+31:2 (2010) you can read Don's announcement of his new typesetting engine i\TEX:
+\quotation {Output can be automatically formatted for lasercutters, embroidery
+machines, \THREED\ printers, milling machines, and other \CNC\ devices \unknown}.
+Now that is something that Word can't do!

+
+Here I will shortly wrap up the state of \LUATEX\ and \CONTEXT\ in fall 2018. I
+made the first draft of this article as preparation for the \CONTEXT\ meeting
+where we also discussed the future. I updated the text afterwards to match the
+decisions made there. It's also a personal summary of thoughts and discussions
+with team members about where to move next.
+
+\stopsection
+
+\startsection[title={The state of affairs}]
+
+After a dozen years the development of \LUATEX\ has reached a state where adding
+more functionality and|/|or opening up more of the internals makes not much
+sense. Apart from fixes and maybe some minor extensions, version 1.10 is what you
+get. Users can do enough in \LUA\ and there is not much to gain in convenience
+and performance. Of course some of the code can and will be cleaned up, as we
+still see the effects of going from \PASCAL\ to \CWEB\ to \CCODE. In the process
+consistency is on the radar so we might occasionally add a helper. But we also
+don't want to move too far away from the original code, which is for instance why
+we keep names, keys and other properties found in original \TEX, which in turn
+leads to some inconsistencies with extensions added over time. We have to accept
+that.
+
+Because \LUATEX\ development is closely related to \CONTEXT\ development,
+especially \MKIV, we've also reached the moment that we can get rid of some older
+code and assume the latest \LUATEX\ to be used. Because we do so much in \LUA\
+the question is always to what extent the benefits outweigh the drawbacks. Just
+in case you wonder why we use \LUA\ extensively, the main reason is that it is
+easier and more efficient to manage data in this language and modern typesetting
+needs much data. It also permits us to extend regular \TEX\ functionality. But,
+one should not overrate the impact: we still let \TEX\ do what \TEX\ is best at!
+
+Performance is quite important. It doesn't make sense to create a powerful
+typesetting system where processing a page takes a second. We have discussed
+performance before since one of the complaints about \LUATEX\ is that it is slow.
+A simple, basic test is this:
+
+\starttyping
+\starttext
+    \dorecurse{1000}{\input tufte \par}
+\stoptext
+\stoptyping
+
+This involves 1000 times loading a file (and reporting that on the console, which
+can influence runtime), typesetting paragraphs, splitting of a page and of course
+loading fonts and saving to the \PDF\ file. When I run this on a modest machine,
+I get these (relative) timings for the (about) 225 pages:
+
+\starttabulate[|l|c|c|c|c|]
+\BC \TEX\ engine used  \BC \PDFTEX \BC \LUATEX \BC \LUAJITTEX \BC \XETEX \NC \NR
+\BC runtime in seconds \NC 2.0     \NC  3.9    \NC 3.0        \NC 8.4    \NC \NR
+\stoptabulate
+
+Now, as expected the 8 bit \PDFTEX\ is the winner here but \LUATEX\ is not doing
+that bad. I don't know why \XETEX\ is so much slower, maybe because its 64 bit
+binary is less optimal. I once noticed that a 64 bit \PDFTEX\ performed worse on
+such a test than \LUATEX, for which I always use 64 bit binaries.
+
+If you consider that often much more is done than in this example, you can take
+my word that \LUATEX\ quickly outpaces \PDFTEX\ on more complex tasks. In that
+sense it is now our benchmark. It must be said that the \MKIV\ code is probably a
+bit more efficient than the \MKII\ code but that doesn't matter much in this
+simple test because hardly any macro magic happens here; it mostly tests basic
+font processing, paragraph building and page construction. I don't think that I
+can squeeze out more pages per second, at least not without users telling me
+where they encounter bottlenecks that don't result from their style coding. It's
+no problem to write inefficient macros (or styles) so normally a user should
+first carefully check her|/|his own work. Using a more modern \CPU\ with proper
+caching and an \SSD\ helps too.
+
+So, to summarize, we can say that with version 1.10 \LUATEX\ is sort of finished.
+Our mission is now to make \LUATEX\ robust and stable. Things can be added and
+improved, but these are small and mostly consistency related.
+
+\stopsection
+
+\startsection[title={More in \LUA}]
+
+Till now I always managed to add functionality to \CONTEXT\ without hampering
+performance too much. Of course the biggest challenge is always in handling fonts
+and common features like color because that all happens in \LUA. So, the question
+is, what if we delegate more of the core functionality to \LUA ? I will discuss a
+few options because the \CONTEXT\ developers and users need to agree on the path
+to follow. One question there is, are the possible performance hits (which can be
+an inconvenience) compensated by better and easier typesetting.
+
+Fonts, colors, special typesetting features like spaced kerning, protrusion,
+expansion, but also dropped caps, line numbering, marginal notes, tables,
+structure related things, floats and spacing are not open for much discussion.
+All the things that happen in \LUA\ combined with macros is there and will stay.
+But how about hyphenation, paragraph building and page building? And how about a
+leaner and meaner, future safe engine?
+
+Hyphenation is handled in the \TEX\ core. But in \CONTEXT\ already for years one
+can also use a \LUA\ based variant. There is room for extensions and improvements
+there. Interesting is that performance is more or less the same, so this is an
+area where we might switch to the \LUA\ method eventually. It compares to fonts,
+where node mode is more or less the standard and base mode the old way.
+
+Building the paragraphs in \LUA\ is also available in \MKIV, although it needs an
+update. Again performance is not that bad, so when we add features not possible
+(or hard to do) in regular \TEX, it might actually pay of to default to the
+par builder written in \LUA.
+
+The page builder is also doable in \LUA\ but so far I only played a bit with a
+\LUA\ based variant. I might pick up that thread. However, when we would switch to
+\LUA\ there, it might have a bit of a penalty, unless we combine it with some
+other mechanisms which is not entirely trivial, as it would mean a diversion from
+the way \TEX\ does it normally.
+
+How about math? We could at some point do math rendering in \LUA\ but because the
+core mechanism is the standard, it doesn't really makes much sense. It would also
+touch the soul of \TEX. But, I might give it a try, just for fun, so that I can
+play with it a bit. It's typically something for cold and rainy days with some
+music in the background.
+
+We already use \LUA\ in the frontend: locating and reading files in \TEX,
+\XML, \LUA\ and whatever input format. Normalization and manipulation is all
+active and available. The backend is also depending on \LUA, like support for
+special \PDF\ features and exporting to \XML . The engine still handles the page
+stream conversion, font inclusion and object management.
+
+The inclusion of images is also handled by the engine, although in \CONTEXT\ we
+can delegate \PDF\ inclusion to \LUA. Interesting is that this has no performance
+hit.
+
+With some juggling the page stream conversion can also be done in \LUA, and I
+might move that code into the \CONTEXT\ distribution. Here we do have a
+performance hit: about one second more runtime on the 14 seconds needed for the
+300 page \LUATEX\ manual and just over more than half a second on a 11 second
+\LUAJITTEX\ run. The manual has lots of tables, verbatim, indices and uses color
+as well as a more than average number of fonts and much time is spent in \LUA. So
+there is a price to pay there. I tried to speed that up but there is not much to
+gain there.
+
+So, say that we default to \LUA\ based hyphenation, which enables some new
+functionality, \LUA\ based par building, which permits some heuristics for corner
+cases, and \LUA\ based page building, which might result in more control over
+tricky cases. A total performance hit of some 5\% is probably acceptable,
+especially because by that time I might have replaced my laptop and won't notice
+the degrade. This still fits in the normal progress and doesn't really demand a
+roadmap or wider acceptance. And of course we would still use the same strategies
+as implemented in traditional \TEX\ as default anyway.
+
+\stopsection
+
+\startsection[title={A more drastic move}]
+
+More fundamental is the question whether we delegate more backend activity to
+\LUA\ code. If we decide to handle the page stream in \LUA, then the next
+question is, why not also delegate object management and font inclusion to
+\LUA. Now, keep in mind that this is all very \CONTEXT\ specific! Already for
+more than a decade we delegate a lot to \LUA, and also we have a rather tight
+control over this core functionality. This would mean that \CONTEXT\ doesn't
+really need the backend code in the engine. \footnote {For generic packages like
+TikZ we (can) provide some primitive emulators, which is rather trivial to
+implement.}
+
+That situation is actually not unique. For instance, already for a while we don't
+need the \LUATEX\ font loader either, as loading the \OPENTYPE\ files is done in
+\LUA. So, we could also get rid of the font loader code. Currently some code is
+shared with the font inclusion in the backend but that can be isolated.
+
+You can see a \TEX\ engine as being made from several parts, but the core really
+concerns only two processes: reading, storing and expanding macros on the one
+hand, and converting a stream of characters into lines, paragraphs, pages etc.
+Fonts are mostly an abstraction: they are visible in so called glyph nodes as
+font identifier (a number) and character code (also a number) properties. The
+result, nowadays being \PDF, is also an abstraction: at some point the engine
+converts the to be shipped out box in \PDF\ instructions, and in our case,
+relatively simple ones. The backend registers which characters and fonts are used
+and also includes the right resources. But, the backend is not part of the core
+as such! It has been introduced in \PDFTEX\ and is a so called extension.
+
+So, what does that all mean for a future version of \CONTEXT\ and \LUATEX ? It
+means that we can decide to follow up with a \CONTEXT\ that does more in \LUA,
+which means not hard coded in a binary, on the one hand, but that we can also
+decide to strip the engine from non|-|core code. But, given that \LUATEX\ is also
+used in other macro packages, this would mean a different engine. We cannot say
+that \LUATEX\ is stable when we also experiment with core components.
+
+We've seen folks picking up experimental versions assuming that it is a precursor
+to official code. So, in order to move on we need to avoid confusion: we need to
+use another name. Choosing a name is always tricky but as Taco already registered
+the \METATEX\ domain, and because in the \CONTEXT\ distribution you will find
+references to \METATEX, we will use that name for the future engine. Adding \LUA\
+to that name makes sense but then the name would become too long.
+
+The main difference between \METATEX\ and \LUATEX\ would be that the former has
+no file lookup library, no hardcoded font loader, and no backend generator (but
+possibly some helpers, and these need time to evolve). We're basically back where
+\TEX\ started but instead of coding these extensions in \PASCAL\ or \CCODE\ we
+use \LUA. We're also kind of back to when we first started experimenting with
+\LUATEX\ in \CONTEXT\ where test, write and rewrite were going in parallel. But,
+as said, we cannot impose that on a wide audience.
+
+If we go for such a lean and mean follow up, then we can also do a more drastic
+cleanup of obsolete code in \CONTEXT\ (dating from \ETEX, \PDFTEX, \ALEPH, etc.).
+We then are sort of back to where it all started: we go back to the basics. This
+might mean dropping some primitives (one can define them as dummy). Of course we
+could generalize some of the \CONTEXT\ code to provide the kicked out
+functionality but would that pay of? Probably not.
+
+Just for the record: replacing the handling of macros, registers, grouping, etc.\
+to \LUA\ is not really an option as the performance hit would make a large system
+like \CONTEXT\ sort of unusable: it's no option and not even considered (although
+I must admit that I have some experimental \LUA\ based \TEX\ parser code around).
+
+It is quite likely that building \METATEX\ from source for the moment will be an
+option to the build script. But we can also decide to simplify that process,
+which is possible because we only need one binary. But in general we can assume
+that one can generate \METATEX\ and \LUATEX\ from the same source. A first step
+probably is a further isolation of the backend code. The fontloader and file
+handling code already can be made optional.
+
+Given that we only need one binary (it being \LUATEX\ or \METATEX) and nowadays
+only use \OPENTYPE\ fonts, one can even start thinking of a mini distribution,
+possibly with a zipped resource tree, something we experimented with in the early
+days of \LUATEX.
+
+Another though I have been playing with is a better separation between low level
+and high level \CONTEXT\ commands, and whether the low level layer should be more
+generic in nature (so that one can run specific packages on top of it instead of
+the whole of \CONTEXT) but that might not be worth the trouble.
+
+\stopsection
+
+\startsection[title={Interlude}]
+
+If we look at the future, it's good to also look at the past. Opening up \TEX\
+the way we did has many advantages but also potential drawbacks. It works quite
+well in \CONTEXT\ because we ship an integrated package. I don't think that there
+are many users who kick in their own callbacks. It is possible but completely up
+to the user to make sure things work out well. Performance hits, interference,
+crashes: those who interfere with the internals can sort that out themselves. I'm
+not sure how well that works out in other macro packages but it is a time bomb if
+users start doing that. Of course the documented interfaces to use \LUA\ in
+\CONTEXT\ are supported. So far I think we're not yet bitten in the tail. We keep
+this aspect out of the discussion.
+
+Another important aspect is stability of the engine. Sometimes we get suggestions
+for changes or patches that works for a specific case but for sure will have side
+effects on \CONTEXT. Just as we don't test \LATEX\ side effects, \LATEX\ users
+don't check \CONTEXT. And we're not even talking of users who expect their code
+to keep working. A tight control over the source is important but cannot be we
+will not be around for ever. This means that at some point \LUATEX\ should not be
+changed any more, even when we observe side effects we want to get rid of,
+because these side effects can be in use. This is another argument for a stripped
+down engine. The less there is to mess with, the less the mess.
+
+\stopsection
+
+\startsection[title={Audience}]
+
+So how about \CONTEXT\ itself? Of course we can make it better. We can add more
+examples and more documentation. We can try to improve support. The main question
+for us (as developers) is who actually is our audience. From the mails coming to
+the \CONTEXT\ support list it looks like a rather diverse group of users.
+
+At \TEX\ meetings there are often discussions about promoting \TEX. I can agree
+on the fact that even for simple documents it makes a lot of sense to use \TEX,
+but who will take the first hurdles? How many people really produce a lot of
+documents? And how many need \TEX\ after maybe a short period of (enforced) usage
+at the university?
+
+It's not trivial to recognize the possibilities and power of the
+\LUATEX|-|\CONTEXT\ combination. We never got any serious requests for support
+from large organizations. In fact, we do use this combination in a few projects
+for educational publishers, but there it's actually the authors and editors doing
+the work. It's seldom company policy to use tools that efficiently automate
+typesetting. I dare to say that publishers are not really an audience at all:
+they normally delegate the task. They might accept \TEX\ documents but let them
+rekey or adapt far|-|far|-|away and as cheap as possible. Thinking of it, the
+main reason for Don Knuth for writing \TEX\ in the first place was the ability to
+control the look and feel and quality. It were developments at typesetters and
+publishers that triggered development of \TEX . It was user demand. And the
+success of \TEX\ was largely due to the unique personality and competence of the
+author.
+
+System integrators qualify as audience but I fear that \TEX\ is not considered
+hip and modern. It doesn't seem to matter if you can demonstrate that it can do a
+wonderful job efficiently and relatively cheap. Also the fact that an
+installation can be very stable on the long run is of no importance. Maybe that
+audience (market place) is all about \quotation {The more we have to program and
+update regularly, the merrier.}. Marketing \TEX\ is difficult.
+
+Those who render multiple products, maintain manuals, have to render many
+documents automatically qualify as audience. But often company policies,
+preferred suppliers, so called standard tools etc.\ are used as argument against
+\TEX. It's a missed opportunity.
+
+One needs a certain mindset to recognize the potential and the question is, how
+do we reach that audience. Drawing a roadmap for that is not easy but worth
+discussing. We're open for suggestions.
+
+% \footnote {It's kind of interesting that recently the \TEX\ User Group announced
+% its presence on Facebook and Twitter. Apart from wondering how that gets updated,
+% one can also wonder how many potential (or even current) users go there, given
+% that these platforms are subjected to rise and fall. I'm on neither of them and
+% don't plan to. Kids (our future users) that I know already said goodbye to them.
+% We'll see how that works out.}
+
+\stopsection
+
+\startsection[title={Conclusion}]
+
+At the \CONTEXT\ user meeting those present agreed that moving forward this way
+makes sense. This means that we will explore a lean and mean \METATEX\ alongside
+\LUATEX. There is no rush and it's all volunteer work so we will take our time
+for this. It boils down to some reshuffling of code so that we can remove the
+built|-|in font loader, file handling, and probably also \SYNCTEX\ because we can
+emulate that. Then the backend with its font inclusion code will be cleaned up a
+bit (we even discussed only supporting modern wide fonts). It's no big deal to
+adapt \CONTEXT\ to this (so it can and will support both \LUATEX\ and \METATEX).
+Eventually the backend might go away but now we're talking years ahead. By then
+we can also explore the option to make \METATEX\ start out as a \LUA\ function
+call (the main control loop) and become reentrant. There will probably not be
+many changes to the opened up \TEX\ kernel, but we might extend the \METAPOST\
+part a bit (some of that was discussed at the meeting) especially because it is a
+nice tool to visualize big data.
+
+As with \LUATEX\ development we will go in small steps so that we keep a working
+system. Of course \LUATEX\ is always there as stable fallback. The experiments
+will mostly happen in the experimental branch and binaries will be generated
+using the compile farm on the \CONTEXT\ garden, just as happens now. This also
+limits testing and exploring to the \CONTEXT\ community so that there are no side
+effects for mainstream \LUATEX\ usage.
+
+Nowadays, instead if roadmaps, we tend to use navigational gadgets that adapt
+themselves to the situation. On the road by car this can mean a detour and when
+walking around it can be going to suggested points of interest. During the
+excursion at the meeting, we noticed that after the drivers (navigators)
+synchronized their gadget with Jano, the routes that were followed differed a
+bit. We saw cars in front of going a different direction and cars behind us
+arriving from a different direction. So, even when we talk about roadmaps, our
+route can be adapted to the situation.
+
+Now here is something to think about. If you look at the \TEX\ community you will
+notice that it's an aging community. User groups seem to loose members, although
+the \CONTEXT\ group is currently still growing. Fortunately we see a new
+generation taking interest and the \CONTEXT\ users are a pleasant mix and it
+makes me stay around. I see it as an \quote {old timers} responsibility to have
+\TEX\ and its environment in a healthy state by the time I retire from it
+(although I have no plans in that direction). In parallel to the upcoming
+development I think we will also see a change in \TEX\ use and usage. This aspect
+was also discussed at the meeting and for sure will get a follow up on the
+mailing lists and future meetings. It might as well influence the decisions we
+make the upcoming years. So far \TEX\ has never failed us in it's flexibility and
+capacity to adapt, so let's end on that positive note.

+
+\startsubject[title=Introduction]
+
+How stable is \CONTEXT ? This question is hard to answer. For instance \MKII\
+hasn't changed for years and seems to work quite well: no changes equals
+stability. Those who use it can do with what it offers. The potentially sensitive
+dependencies on for instance fonts are probably absent because there is not much
+development in the 8 bit fonts arena. As long as these are available we're okay,
+in fact, \OPENTYPE\ fonts are more a moving target and therefore less stable.
+
+What do we mean by stable? The fundamental differences between an 8 bit engine
+(and fonts) and an \UNICODE\ aware engine able to handle \OPENTYPE\ fonts is
+substantial which is why we dropped some functionality and added some relevant
+new. One can consider that a problem but in practice using fonts has become
+easier so no one is hurt by it. Here we need to keep in mind that \PDFTEX\ is
+really stable: it uses fonts and technology that doesn't change. On the other
+hand \XETEX\ and \LUATEX\ follow new trends. Thereby \XETEX\ uses libraries,
+which introduces a dependency and instability, while \LUATEX\ assumes solutions
+in \LUA\ which means that users and macro writers can tweak and thereby also
+introduce instability (but at least one can adapt that code).
+
+Due to the way the user interface is set up, it is unlikely that \CONTEXT\ will
+change. But the fact that we now have \LUA\ available means that many commands
+have been touched. Most behave compatible, some have more functionality, and of
+course we have a \LUA\ interface. We include a lot of support code which also
+lessens dependencies.
+
+The user input is normally \TEX\ but when you use \XML\ the move to \MKIV\ meant
+that we dropped the \MKII\ way of dealing with it in favour of a completely new
+mechanism. I get the impression that those using \XML\ don't regret that change.
+Talking of stability the \MKIV\ \XML\ interface is typically a mechanism that is
+stable and might change little. We can add new trickery but the old stays as it
+is.
+
+If we look at the output, there is \DVI\ and \PDF. In \MKII\ the \DVI\ could
+become \POSTSCRIPT. As there are different \DVI\ post|-|processors the backend
+code was using a plug|-|in model. Contrary to other macro packages there was only
+one so called format that could adapt itself to the required (engine specific)
+output. A \CONTEXT\ run has always been managed by a wrapper so users were not
+bothered much by what \TEX\ engine they used and|/|or what backend was triggered.
+This changed with \MKIV\ where we use just \LUATEX, always produce \PDF\ and
+optionally can export \XML. But again the run is managed by a wrapper, which
+incidentally is written in \LUA\ and thereby avoids dependencies on for instance
+\PERL, \RUBY\ or \PYTHON, which are moving targets, use libraries and additional
+user code, and thereby are potentially instable too.
+
+The \PDF\ code that is produced is a mix of what the engine spits out and what
+the macro package injects. The code is normally rather simple. This means that
+it's no big deal to support the so called standards. It also means that we can
+support advanced interactivity and other features but these also depends on the
+viewers used. So, stability here is more fluent, for instance because the \PDF\
+standard evolves and|/|or we need to adapt to viewers. Special demands like
+tagged \PDF\ have been supported right from the start but how that evolves
+depends mostly on input from users who need it. Again, that is less important
+(and crucial) for stability than the rendering capabilities.
+
+The fact that we use \LUA\ creates a dependency on that language but the reason
+that we use it is {\em because} it is so stable. We follow the updates and so far
+that worked out well. Now, say that we had a frozen version of \CONTEXT\ 2010 and
+\LUATEX\ 1.09 that uses \LUA\ 5.3, would that work? First of all, in 2010
+\LUATEX\ itself was evolving so the answer is probably \quotation {no}, unless
+one adds a few compatibility patches. I'm not going to try it. The change from
+5.1 to 5.2 to 5.3 was not really a problem I think and the few issues could be
+dealt with easily. If you want long term stability and use a lot of \LUA\ code
+you can take it into account when coding. Avoiding external libraries is a good
+start.
+
+Fonts are more than before moving targets. So, if you want stability there you
+should save them with your document source. The processing of them has evolved
+and has been improved over time. By now it's rather stable. More recent code can
+catch more issues and fixes are relatively easy. But it's an area that you always
+need to check when you update an old distribution. The same is true for language
+related hyphenation patterns and script specific support. The community is no
+longer leading in the math department either (\OPENTYPE\ math is a \MICROSOFT\
+invention). But, the good news is that the \TEX\ ecosystem is always fast to
+adapt and can also often provide more functionality.
+
+Vertical spacing, in fact spacing in general is an aera that can always be
+improved, so there is where you can expect changed. The same is true for side
+floats or mechanisms where content is somehow attached to other moving content,
+for instance marginal notes.
+
+But code dealing with fonts, color, scripts, structure, and specific features
+that once written don't need more, will not change that much. As mentioned for
+fonts, like any resource, we also depend on third parties. Colors can relate to
+standards, but their main properties are unchanged. Support for specific scripts
+can (and will) be improved due to user input and demands so there the users also
+influence stability. Structure doesn't really influence the overall rendering,
+but the way you set it up does, but that's user styling. Of course during the
+transition from \MKII\ to \MKIV\ and the evolution of \LUATEX\ things could be
+broken, but fixing something structural seldom relates to rendering. If for
+instance we improve the interpretation of \BIBTEX\ input , which can be real
+messy, that involves data processing, nor rendering. When we improve support for
+the \APA\ standard, which is complex, it might involve rendering but then that's
+asked for and expected. One cannot do better than the input permits.
+
+\stopsubject
+
+\startsubject[title=Publishers]
+
+When discussing stability and especially stability as requirement we need to look
+at the way \CONTEXT\ is used. So let's look at a few scenarios. Say that a
+publisher gets a camera ready book from an author in \PDF\ format. In that
+case the author can do all tweaks needed. Now say that the publisher also wants
+the source code in a format that makes reuse possible.
+
+But let's face reality. Will that publisher really reformat the document in \PDF\
+again? It's very unlikely. First of all the original \PDF\ can be kept, and
+second, a reformat only makes sense after updating the content or going for a
+completely different layout. It's basically a new book then. In that case literal
+similarity of output is irrelevant. It is a cheap demand without much substance.
+
+When the source is used for a different purpose the tool used to make the \PDF\
+is irrelevant. In that case the coding of the source can matter. If it is in some
+dialect of \TEX, fine, one has to convert it anyway (to suit the other usage). If
+there is an \XML\ export available, fine too as it can be transformed, given that
+the structure is rich enough, something that is unlikely to have been checked
+when the original was archived. Then there could have been the demand for a
+document in some other format and who can guarantee stability of the tools used
+there? Just look at how \MICROSOFT\ Word evolved, or for that matter, its
+competitors. On the average \TEX\ is more stable as one can snapshot a \TEX\ tree
+and run binaries for years, if needed, in a virtual machine.
+
+So, I don't think that a publisher is of any relevance in the discussion about
+stability. Even if we can clearly define what a publisher is, I doubt if
+publishers themselves can be considered long term stable organizations. Not
+today. I'm not sure if (especially the large) publishers really deserve a place
+in the discussion about stability but I'm willing to discuss that when I run into
+one.
+
+The main problem that an author can face when being confronted with the stability
+issue this way is that the times are long gone that publishers have a clue about
+what \TEX\ is, how it evolved and how it always had to and did adapt to changing
+requirements. If you're lucky you will run into someone who does know all this.
+They're normally a bit older and have seen the organization from any angles and
+therefore are fun to work with.
+
+But even then, rendering issues are often not high on their agenda. Outsourcing
+often has become the modus operandi which basically brings us to the second group
+involved in this discussion: suppliers.
+
+\stopsubject
+
+\startsubject[title=Suppliers]
+
+I don't know many suppliers other than the ones we ran into over a few decades.
+At least where I live the departments that are responsible for outsourcing
+typesetting like to deal with only a few large suppliers, interestingly because
+they assume that they are stable. However, in my experience hardly any of those
+seem to have survived. (Of course one can wonder if long term commitment really
+is that important in a world where companies change so fast.) This is somewhat
+obscured by the fact that publishers themselves merge, reorganize, move people
+around, etc. so who can check on the stability of suppliers. It is definitely a
+fact that at least recently hardly any of them played a rol of any relevance in
+the development of stable tools. In the past the membership of \TEX\ user groups
+contained people working at publishers and suppliers but that has changed.
+
+Let's focus on the suppliers that somehow use \TEX\ and let's consider two kind
+of suppliers: small ones, one were only a few people work, and large ones. The
+small ones depend on stable \TEX\ distributions, like \TEX Live where they can
+get the resources from: styles, fonts, patterns, binaries. If they get the
+authors \TEX\ files they need to have that access. They have to rework that input
+into what the customer demands and that likely involves tweaks. So, maybe they
+have developed their own additional code. For that code, stability is their own
+responsibility. Did they tweak core code of a macro package? Fine, but you might
+have it coming when you update. You cannot expect the evolving free meal world to
+stick to your commercial needs. A supplier can play safe and somehow involve the
+developers of macro packages or consult them occasionally, but does that really
+happen often? Interesting is that a few times that I was asked for input it was
+also wrapped in obscurity, as if some holy grail of styling was involved, while
+it's quite likely that the developer of a macro package can write such a style
+(or extra code) easily and probably also better. There really is not that much
+unique code around.
+
+Small suppliers can be on mailing lists where they can contribute, get feedback,
+provide testing, etc. They are part of a process and as such have some influence
+on stability. If they charge by the page, then a change in their tools can be
+reflected in what they charge. Basically redoing a book (or so) after a decade is
+doing a new job. And adapting to some new options in a package, as part of a
+typesetting job is probably no big deal. Is commercial really more stable than
+open source free software? Probably not, except from open source software
+developers whose real objective is to eventually sell their stuff to some company
+(and cash) and even accept it to be ditched. Small suppliers are more flexible.
+
+The large suppliers are a different group. They often guard their secrets and
+stay in the dark. They probably seldom share (fundamental) code and information.
+If they are present in a community it can be for marketing reasons. If at some
+point a large supplier would demand stability, then my first response would be:
+sure I can make you a stable setup and maybe even provide intermediate patches
+but put your money where your mouth is. But that never happened and I've come to
+the conclusion that we can safely ignore that group. The \TEX\ user groups create
+distributions and have for instance funded font development and it are the common
+users who paid for that, not the scale ones. To some extent this is actually good
+because large (software related) organizations often have special agendas that
+can contradict what we aim at in the long term.
+
+From the authors perspective there is a dilemma here. When you submit to a
+publisher who outsources, it can be a demand to deliver in a specific \TEX\
+format. Often a \PDF\ comes with the source then, so that the intended rendering
+is known. Then that source goes to a supplier who then (quite likely) redoes a
+lot of the coding in some stable subset, maybe even in a very old version of the
+macro package. If I were such an author I'd render the document in \quote {as
+stupid as possible mode} because you gain nothing by spending time on the looks.
+So, stability within the package that you use is easy and translation from one to
+another probably also. It's best to check beforehand what will happen with your
+source and let stability, if mentioned, be their problem. After all they get paid
+for it.
+
+Suppliers seldom know \CONTEXT. An interesting question is if they really know
+the alternatives well, apart from the bit they use. A well structured \CONTEXT\
+source (or probably any source) is often easy to convert to another format. You
+can assume that a supplier has tools for that (although we're often surprised
+about the poor quality of tools used). Often the strict demand for some kind of
+format is an excuse for lack of knowledge. Unfortunately you need a large author
+base to change that attitude.
+
+\stopsubject
+
+\startsubject[title=Authors]
+
+Before we move to some variants of the above, first I will look at stability from
+the authors perspective. When a book is being written the typesetting more or
+less happens as part of the process. The way it looks can influence the way you
+write and vise versa. Once the book is done it can go in print and, unless you
+were using beta versions of \CONTEXT\ and updated frequently. Normally you will
+try to work in a stable setup. Of course when a user asks for additional features
+while working on a project, he or she should also accept other beta features
+and side effects.
+
+After a few years an author might decide to update the book. The worst that can
+happen is that the code doesn't run with the latest \CONTEXT. This is not so
+likely because commands are upward compatible. However, the text might come out a
+bit different, for instance because different fonts or patterns are used. But on
+the average paragraphs will come out the same in \TEX. You can encounter
+differences in the vertical spacing and page breaks, because that is where
+improvements are still possible. If you use conceptually and implementation wise
+complex mechanism like side floats, you can also run into compatibility issues.
+But all these don't really matter much because the text will be updated anyway
+and fine|-|tuning of page breaks (if at all) happens at the end. The more you try
+to compete with desk top publishing, and the more tweaks you apply, the greater
+is the risk that you introduce instability. It is okay for a one|-|time job, but
+when you come back to it after a decade, be prepared for surprises.
+
+Even if you stick to the original coding, it makes sense to sacrifice some of that
+stability if new mechanisms have become available. For instance, if you use
+\METAPOST, better ways to solve your problem might have become available. Or if
+you document is 15 years old, a move from \MKII\ to \MKIV\ is a valid option,
+in which case you might also consider using the latest fonts.
+
+Of course, when you made a style where you patched core code, you can expect
+problems, because anything not explicitly mentioned in the interface definition
+files is subjected to change. But you probably see that coming anyway.
+
+So, is an author (or stand alone user) really dependent on stability? Probably
+less than thought. In fact, the operating system, internet and browsers,
+additional tools: all change over time and one adapts. It's something one can
+live with. Just see how people adapt to phones, tablets, social media, electric
+cars, etc. As long as the document processes and reasonable output is generated
+it's fine. And that is always what we aim at! After all we need to be able to use
+it ourselves, don't we?
+
+\stopsubject
+
+\startsubject[title=Projects]
+
+Although it is often overlooked as valid alternative in rendering in large scale
+projects, \CONTEXT\ is perfect as component in a larger whole. Something goes
+in, something comes out. In a long term project one can just install a minimal
+distribution, write styles, and run it for ages. Use a virtual machine and
+we're talking decades without any change. And, when one updates, it's easy to check
+if all still works. Often the demands and styles are simple and predictable. It's
+way more likely that a hard coded solution in some large programming environment has
+stability issues than that the \CONTEXT\ bit has.
+
+If \CONTEXT\ is used in for instance documentation of (say) software, again there
+is no real issue. Such documents are simple, evolve and therefore have no stable
+page flow, and updating \CONTEXT\ is not needed if the once decided upon coding
+is stable. You don't need the latest features. We've written styles and setups for
+such tasks and indeed they run for ages.
+
+It can make me smile to see how much effort sometimes goes in low quality
+rendering where \CONTEXT\ could do a way better job with far less investment in
+time and money but where using some presumed stable toolkit is used instead, one
+that comes with expensive licensing, from companies that come and go but shine in
+marketing. (A valid question is to what extent the quality of and care for
+documentation reflects the core products that a company produces, at least under
+the hood.)
+
+The biggest hurdle in setting up a decent efficient workflow is that it has to be
+seen as a project: proper analysis, proper planning, prototyping and testing,
+etc. You invest first and gain later. When dealing with paper many publishers
+still think in price per page and have problems seeing that a stable mostly
+automated flow in the end can result in a ridiculous low price per page,
+especially in typesetting on demand.
+
+\stopsubsubject
+
+\startsubject[title=Hybrids]
+
+Last I will mention a setup that we sometimes are involved in. An author writes
+books and uses \TEX. The publisher is okay with that and adds some quality
+assurance but in the end the product comes from the author. Maybe images are
+oursourced (not always for the better) but these can be handled easily. It can be that
+a copy|-|editor is involved and that person also then has to use \TEX\ of course,
+or feedback to the author.
+
+Publishers, and this really depends on knowledgeable persons, which as said can
+be fun to work with, can look beyond paper and also decide for additional
+materials, for instance web pages, interactive exercises, etc. In that case
+either \CONTEXT\ input has to be available as \XML\ (an export) or (often better)
+\XML\ is the starting point for multiple output. Contrary to what is believed,
+there are authors out there who have no problem coding in \XML\ directly. They
+think in structured content and reuse! The fact that they can hit a button in the
+editor and see the result in \PDF\ helps a lot. It just works.
+
+Here stability is either achieved by simply not updating during a project. There
+are however cases where an update is needed, for instance because demands
+changed. An example is a project where \ASCIIMATH\ is used which is a moving
+target. Of course one can update just that module, and often that works, but not
+when a module uses some new improved core helpers. Another example is additional
+proofing options.
+
+The budget of such projects seldom permit patching an existing distribution, so
+we then just update to the latest but not after checking if the used style works
+okay. There is no author involvement in this. Depending on the workflow, it can
+even be that the final rendering which involves fine tuning (side) float placement
+or page breaks (often educational documents have special demands) is done by us
+using special directives.
+
+Such hybrid workflows are quite convenient for all parties. The publisher works
+with the author who likes using these tools, the author can do her or his thing
+in the preferred way, and we do what we're best in: supporting this. And it
+scales up pretty well too if needed, without much costs for the publishers.
+
+\stopsubject
+
+\startsubject[title=Conclusion]
+
+So what can we conclude with respect to the demand for stability? First of course
+that it's important that our files keep running well. So, functionality should be
+stable. Freezing a distribution will make sure that during project you don't run
+into issues. Many \CONTEXT\ users update frequently in order to benefit from the
+latest additions. Most will not be harmed by this, but when something really
+breaks it's users like those on the \CONTEXT\ support list (who often also
+contribute in helping out other users) that are listened to first. Publishers
+demands play no role in this, if only because they also play no role in
+typesetting, and if they want to they should also contribute. The same is true
+for large suppliers. We're talking of free software often written without any
+compensation so these parties have no say in the matter unless they pay for it.
+It's small suppliers, authors and general users that matter most. If \CONTEXT\ is
+part of a workflow that we support, of course stability is guaranteed quite well,
+and those paying for that never have an issue with better solutions popping up.
+In fact, \CONTEXT\ is often just a tool then, one that does the job and questions
+about stability don't matter much in practice, as long as it does the job well.
+
+The main engine we use, \LUATEX, will be quite stable from version 1.10 and we'll
+try to make sure that newer versions are capable of running an older \CONTEXT,
+which is easier when no fundamental changes happen in the engine. Maybe a stripped
+down version of \LUATEX\ for \CONTEXT\ can facilitate that objective even more.
+
+Users themselves can try to stick to standard \CONTEXT\ features. The more tricks
+you apply, the less stable your future might be. Most mechanism are not evolving
+but some, like those that deal with columns, might become better over time. But
+typesetting in columns is often a one|-|shot adventure anyway (and who needs
+columns in the future).
+
+Of one thing users can be sure. There will never be a \CONTEXT\ professional or
+\CONTEXT\ enterprise. There is only one variant. All users get the same
+functionality and policies don't change suddenly. There will be no lock in to some
+cloud or web based service either. Of course one can hire us for support of any
+kind but that's independent of the distributed package. There is support by users
+for users on mailing lists and other media. That itself can also guard stability.
+
+But, always keep in mind that stability and progress, either of not driven by the
+environment that we operate in, can be in conflict.

+\startsection[title=Introduction]
+
+The following text was written as preparation for a 2018 talk at Bacho\TEX, which
+has this theme. It's mostly a collection of thoughts. It was also more meant as a
+wrapup for the presentation (possibly with some discussions) than an article.
+
+\stopsection
+
+\startsection[title=Attraction]
+
+There are those movies where some whiz-kid sits down behind a computer, keys in a
+few commands, and miracles happen. Ten fingers are used to generate programs that
+work immediately. It's no problem to bypass firewalls. There is no lag over
+network connections. Checking massive databases is no big deal and there's even
+processing power left for real time visualization or long logs to the terminal.
+
+How boring and old fashioned must a regular edit||run||preview cycle look
+compared to this. If we take this 2018 movie reality as reference, in a time when
+one can suck a phone empty with a simple connection, pull a hard drive from a
+raid five array and still get all data immediately available, when we can follow
+realtime whoever we want using cameras spread over the country, it's pretty clear
+that this relatively slow page production engine \TEX\ has no chance to survive,
+unless we want to impress computer illiterate friends with a log flying by on the
+console (which in fact is used in movies to impress as well).
+
+On YouTube you can find these (a few hours) sessions where Jacob Collier
+harmonizes live in one of these Digital Audio Workstation programs. A while later
+on another channel June Lee will transcribe these masterpieces into complex
+sheets of music by ear. Or you can watch the weekly Wintergatan episodes on
+building the Marble Machine from wood using drilling, milling, drawing programs
+etc. There are impressive videos of multi|-|dimensional led arrays made by hand
+and controlled by small computers and robots that solve Rubic Cubes. You can be
+impressed by these Animusic videos, musicians show their craftmanship and
+interesting informative movies are all over the place. I simply cannot imagine
+millions of kids watching a \TEX\ style being written in a few hours. It's a real
+challenge for an attention span. I hope to be proven wrong but I fear that for
+the upcoming generation it's probably already too late because the \quote {whow}
+factor of \TEX\ is low at first encounter. Although: picking up one of Don Knuths
+books can have that effect: a nice mixture of code, typesetting and subtle
+graphics, combined with great care, only possible with a system like \TEX.
+
+\starttheme
+    Biology teaches us that \quote {cool} is not a recipe for \quote {survival}.
+    Not all designs by nature look cool, and it's only efficiency and
+    functionality that matters. Beauty sometimes matters too but many functional
+    mechanisms can do without. So far \TEX\ and its friends were quite capable to
+    survive so there must be something in it that prevents it to be discarded.
+    But survival is hard to explain. So far \TEX\ just stayed around but lack of
+    visual attraction is a missing competitive trait.
+\stoptheme
+
+\stopsection
+
+\startsection[title=Satisfaction]
+
+Biology also teaches us that chemistry can overload reason. When we go for
+short|-|term pleasure instead of long|-|term satisfaction (Google for Simon Sinek
+on this topic), addiction kicks in (for instance driven by crossing the dopamine
+thresholds too often, Google for Robert Sapolsky). Cool might relate more to
+pleasure while satisfaction relates to an effort. Using \TEX\ is not that cool
+and often takes an effort. But the results can be very satisfying. Where \quote
+{cool} is rewarding in the short term, \quote {satisfaction} is more a long term
+effect. So, you probably get the best (experience) out of \TEX\ by using it a
+lifetime. That's why we see so many old \TEX ies here: many like the rewards.
+
+If we want to draw new users we run into the problem that humans are not that
+good in long term visions. This means that we cannot rely on showing cool (and
+easy) features but must make sure that the long term reward is clear. We can try
+to be \quote {cool} to draw in new users, but it will not be the reason they
+stay. Instant success is important for kids who have to make a report for school,
+and a few days \quotation {getting acquainted with a program} doesn't fit in.
+It's hard to make kids addicted to \TEX\ (which could be a dubious objective).
+
+\starttheme
+    As long as the narrative of satisfaction can be told we will see new users.
+    Meetings like Bacho\TEX\ is where the narrative gets told. What will happen
+    when we no longer meet?
+\stoptheme
+
+\stopsection
+
+\startsection[title=Survival]
+
+Survival relates to improvements, stability and discarding of weak aspects.
+Unfortunately that does not work out well in practice. Fully automated
+multi||columns typesetting with all other elements done well too (we just mention
+images) is hard and close to impossible for arbitrary cases, so nature would have
+gotten rid of it. Ligatures can be a pain especially when the language is not
+tagged and some kind of intelligence is needed to selectively disable them. They
+are the tail of the peacock: not that handy but meant to be impressive. Somehow
+it stayed around in automated typesetting, in biology it would be called a freak
+of nature: probably a goodbye in wildlife. And how about page breaks on an
+electronic device: getting rid of them would make the floating figures go away
+and remove boundary conditions often imposed. It would also make widows and clubs
+less of a problem. One can even wonder if with page breaks the windows and clubs
+are the biggest problems, and if one can simply live with them. After all, we can
+live with our own bodily limitations too. After all, (depending on what country
+you live in) you can also live with bad roads, bad weather, polution, taxes, lack
+of healthcare for many, too much sugar in food, and more.
+
+
+\starttheme
+    Animals or plants that can adapt to live on a specific island might not
+    survive elsewhere. Animals or plants introduced in an isolated environment
+    might quickly dominate and wipe out the locals. What are the equivalents in
+    our \TEX\ ecosystem?
+\stoptheme
+
+\stopsection
+
+\startsection[title=Niches]
+
+But arguments will not help us determine if \TEX\ is the fittest for survival.
+It's not a rational thing. Humans are bad in applying statistics in their live,
+and looking far ahead is not a treat needed to survive. Often nature acts in
+retrospect. (Climbing mount probability by Richard Dawkins). So, it doesn't
+matter if we save time in the future if it complicates the current job. If
+governments and companies cannot look ahead and act accordingly, how can we
+extrapolate software (usage) or more specifically typesetting demands. Just look
+at the political developments in the country that hosts this conference. Could we
+have predicted the diminishing popularity of the \EU\ (and disturbing retrograde
+political mess in some countries) of 2018 when we celebrated the moment Poland
+joining the \EU\ at a Bacho\TEX\ campfire?
+
+Extrapolating the future quality of versions of \TEX\ or macro packages also doesn't
+matter much. With machine learning and artificial intelligence around the corner and
+with unavoidable new interfaces that hook into our brains, who knows what systems
+we need in the future. A generic flexible typesetting system is probably not the
+most important tool then. When we discuss quality and design it gets personal so
+a learning system that renders neutrally coded content into a form that suits
+an individual, demands a different kind of tool than we have now.
+
+On the short term (our live span) it makes more sense to look around and see how
+other software (ecosystems) fare. Maybe we can predict \TEX's future from that.
+Maybe we can learn from others mistakes. In the meantime we should not flatter
+ourselves with the idea that a near perfect typesetting system will draw attention
+and be used by a large audience. Factors external to the community play a too
+important role in this.
+
+\starttheme
+    It all depends on how well it fits into a niche. Sometimes survival is only
+    possible by staying low on the radar. But just as we destroy nature and kill
+    animals competing for space, programs get driven out of the software world.
+    On a positive note: in a project that provides open (free) math for schools
+    students expressed to favour a printed book over \WEB|-|only (one curious
+    argument for \WEB\ was that it permits easier listening to music at the same
+    time).
+\stoptheme
+
+\stopsection
+
+\startsection[title=Dominance]
+
+Last year I installed a bit clever (evohome) heating control system. It's
+probably the only \quotation {working out of the box} system that supports 12
+zones but at the same time it has a rather closed interface as any other. One can
+tweak a bit via a web interface but that one works by a proxy outside so there is
+a lock in. Such a system is a gamble because it's closed and we're talking of a
+20 year investment. I was able to add a layer of control (abusing \LUATEX\ as
+\LUA\ engine and \CONTEXT\ as library) so let's see. When I updated the boiler I
+also reconfigured some components (like valves) and was surprised how limited
+upgrading was supported. One ends up with lost settings and weird interference
+and it's because I know a bit of programming that I kept going and managed to add
+more control. Of course, after a few weeks I had to check a few things in the
+manuals, like how to enter the right menu.
+
+So, as the original manuals are stored somewhere, one picks up the smart phone
+and looks for the manual on the web. I have no problem with proper \PDF\ as a
+manual but why not provide a simple standard format document alongside the fancy
+folded A3 one. Is it because it's hard to produce different instances from one
+source? Is it because it takes effort? We're talking of a product that doesn't
+change for years.
+
+\starttheme
+    The availability of flexible tools for producing manuals doesn't mean that
+    they are used as such. They don't support the survival of tools. Bad examples
+    are a threat. Dominant species win.
+\stoptheme
+
+\stopsection
+
+\startsection[title=Extinction]
+
+When I was writing this I happened to visit a bookshop where I always check the
+SciFi section for new publications. I picked out a pocket and wondered if I had
+the wrong glasses on. The text was wobbling and looked kind of weird. On close
+inspection indeed the characters were kind of randomly dancing on the baseline
+and looked like some 150 \DPI\ (at most) scan. (By the way, I checked this the
+next time I was there by showing the book to a nephew.) I get the idea that quite
+some books get published first in the (more expensive) larger formats, so
+normally I wait till a pocket size shows up (which can take a year) so maybe here
+I had to do with a scan of a larger print scaled down.
+
+What does that tell us? First of all that the publisher doesn't care about the
+reader: this book is just unreadable. Second, it demonstrates that the printer
+didn't ask for the original \PDF\ file and then scaled down the outline copy. It
+really doesn't matter in this case if you use some high quality typesetting
+program then. It's also a waste of time to talk to such publishers about quality
+typesetting. The printer probably didn't bother to ask for a \PDF\ file that
+could be scaled down.
+
+\starttheme
+    In the end most of the publishing industry will die and this is just one of
+    the symptoms. Typesetting as we know it might fade away.
+\stoptheme
+
+\stopsection
+
+\startsection[title=Desinterest]
+
+The newspaper that I read has a good reputation for design. But why do they need
+to drastically change the layout and font setup every few years? Maybe like an
+animal marking his or her territory a new department head also has to put a mark
+on the layout. Who knows. For me the paper became pretty hard to read: a too
+light font that suits none of the several glasses that I have. So yes, I spend
+less time reading the paper. In a recent commentary about the 75 year history of
+the paper there was a remark about the introduction of a modern look a few
+decades ago by using a sans serif font. I'm not sure why sans is considered
+modern (most handwriting is sans) and to me some of these sans fonts look pretty
+old fashioned compared to a modern elegant serif (or mix).
+
+\starttheme
+    If marketing and fashion of the day dominate then a wrong decision can result
+    in dying pretty fast.
+\stoptheme
+
+\stopsection
+
+\startsection[title=Persistence]
+
+Around the turn of the century I had to replace my \CD\ player and realized that it
+made more sense to invest in ripping the \CD's to \FLAC\ files and use a decent
+\DAC\ to render the sound. This is a generic approach similar to processing
+documents with \TEX\ and it looks as future proof as well. So, I installed a
+virtual machine running SlimServer and bought a few SlimDevices, although by that
+time they were already called SqueezeBoxes.
+
+What started as an independent supplier of hardware and an open source program
+had gone the (nowadays rather predictable) route of a buy out by a larger company
+(Logitech). That company later ditched the system, even if it had a decent share
+of users. This \quotation {start something interesting and rely on dedicated
+users}, then \quotation {sell yourself (to the highest bidder)} and a bit later
+\quotation {accept that the product gets abandoned} is where open source can fail
+in many aspects: loyal users are ignored and offended with the original author
+basically not caring about it. The only good thing is that because the software
+is open source there can be a follow up, but of course that requires that there
+are users able to program.
+
+I have 5 small boxes and a larger transporter so my setup is for now safe from
+extinction. And I can run the server on any (old) \LINUX\ or \MSWINDOWS\
+distribution. For the record, when I recently connected the 20 year old Cambridge
+CD2 I was surprised how well it sounded on my current headphones. The only
+drawback was that it needs 10 minutes for the transport to warm up and get
+working.
+
+In a similar fashion I can still use \TEX, even when we originally started using
+it with the only viable quality \DVI\ to \POSTSCRIPT\ backend at that time
+(\DVIPSONE). But I'm not so sure what I'd done if I had not been involved in the
+development of \PDFTEX\ and later \LUATEX . As an average user I might just have
+dropped out. As with the \CD\ player, maybe someone will dust off an old \TEX\
+some day and maybe the only hurdle is to get it running on a virtual retro
+machine. Although \unknown\ recently I ran into an issue with a virtual machine
+that didn't provide a console after a \KVM\ host update, so I'm also getting
+pessimistic about that escape for older programs. (Not seldom when a library
+update is forced into the \LUATEX\ repository we face some issue and it's not
+something the average user want (or is able to) cope with.)
+
+\starttheme
+    Sometimes it's hard to go extinct, even when commerce interfered at some
+    point. But it does happen that users successfully take (back) control.
+\stoptheme
+
+\stopsection
+
+\startsection[title=Freedom]
+
+If you buy a book originating in academia written and typeset by the author,
+there is a chance that it is produced by some flavour of \TEX\ and looks quite
+okay. This is because the author could iterate to the product she or he likes.
+Unfortunately the web is also a source of bad looking documents produced by \TEX.
+Even worse is that many authors don't even bother to set up a document layout
+properly, think about structure and choose a font setup that matches well. One
+can argue that only content matters. Fine, but than also one shouldn't claim
+quality simply because \TEX\ has been used.
+
+I've seen examples of material meant for bachelor students that made me pretend
+that I am not familiar with \TEX\ and cannot be held responsible. Letter based
+layouts on A4 paper, or worse, meant for display (or e|-|book devices) without
+bothering to remove the excessive margins. Then these students are forced to use
+some collaborative \TEX\ environment, which makes them dependent on the quality
+standards of fellow students. No wonder that one then sees dozens of packages
+being loaded, abundant copy and paste and replace of already entered formulas and
+interesting mixtures of inline and display math, skips, kerns and whatever can
+help to make the result look horrible.
+
+\starttheme
+    Don't expect enthusiast new users when you impose \TEX\ but take away freedom
+    and force folks to cooperate with those with lesser standards. It will not
+    help quality \TEX\ to stay around. You cannot enforce survival, it just
+    happens or not, probably better with no competition or with a competition so
+    powerful that it doesn't bother with the niches. In fact, keeping a low
+    profile might be best! The number of users is no indication of quality,
+    although one can abuse that statistic selectively?
+\stoptheme
+
+\stopsection
+
+\startsection[title=Diversity]
+
+Diversity in nature is enormous. There are or course niches, but in general there
+are multiple variants of the same. When humans started breeding stock or
+companion animals diversity also was a property. No one is forcing the same dog
+upon everyone or the same cow. However, when industrialization kicks in things
+become worse. Many cows in our country share the same dad. And when we look at
+for instance corn, tomatoes or whatever dominance is not dictated by what nature
+figures out best, but by what commercially makes most sense, even if that means
+that something can't reproduce by itself any longer.
+
+In a similar way the diversity of methods and devices to communicate (on paper)
+at some point turns into commercial uniformity. The diversity is simply very
+small, also in typesetting. And even worse, a user even has to defend
+her|/|himself for a choice of system (even in the \TEX\ community). It's just
+against nature.
+
+\starttheme
+    Normally something stays around till it no longer can survive. However, we
+    humans have a tendency to destroy and commerce is helping a hand here. In
+    that respect it's a surprise that \TEX\ is still around. On the other hand,
+    humans also have a tendency to keep things artificially alive and even
+    revive. Can we revive \TEX\ in a few hundred years given the complex code
+    base and Make infrastructure?
+\stoptheme
+
+\stopsection
+
+\startsection[title=Publishing]
+
+What will happen with publishing? In the production notes of some of my recently
+bought books the author mentions that the first prints were self|-|published
+(either or not sponsored). This means that when a publisher \quotation {takes
+over} (which still happens when one scales up) not much work has to be done.
+Basically the only thing an author needs is a distribution network. My personal
+experience with for instance \CD's produced by a group of musicians is that it is
+often hard to get it from abroad (if at all) simply because one needs a payment
+channel and mail costs are also relatively high.
+
+But both demonstrate that given good facilitating options it is unlikely that
+publishers as we have now have not much change of survival. Add to the argument
+that while in Gutenbergs time a publisher also was involved in the technology,
+today nothing innovative comes from publishers: the internet, ebook devices,
+programs, etc.\ all come from elsewhere. And I get the impression that even in
+picking up on technology publishers lag behind and mostly just react. Even
+arguments like added value in terms of peer review are disappearing with the
+internet where peer groups can take over that task. Huge amounts of money are
+wasted on short|-|term modern media. (I bet similar amounts were never spend on
+typesetting.)
+
+\starttheme
+    Publishers, publishing, publications and their public: as they are now they
+    might not stay around. Lack of long term vision and ideas and decoupling of
+    technology can make sure of that. Publishing will stay but anyone can
+    publish; we only need the infrastructure. Creativity can win over greed and
+    exploitation, small can win over big. And tools like \TEX\ can thrive in
+    there, as it already does on a small scale.
+\stoptheme
+
+\stopsection
+
+\startsection[title=Understanding]
+
+\quotation {Why do you use \TEX?} If we limit this question to typesetting, you
+can think of \quotation {Why don't you use \MSWORD ?} \quotation {Why don't you use
+Indesign?}, \quotation {Why don't you use that macro package?}, \quotation {Why
+don't you use this \TEX\ engine?} and alike. I'm sure that most of the readers
+had to answer questions like this, questions that sort of assume that you're not
+happy with what you use now, or maybe even suggest that you must be stupid not to
+use \unknown
+
+It's not that easy to explain why I use \TEX\ and|/|or why \TEX\ is good a the
+job. If you are in a one|-|to|-|one (or few) sessions you can demonstrate its
+virtues but \quote {selling} it to for instance a publisher is close to
+impossible because this kind of technology is rather unknown and far from the
+click|-|and|-|point paradigm. It's even harder when students get accustomed to
+these interactive books from wherein they can even run code snippets although one
+can wonder how individual these are when a student has the web as a source of
+solutions. Only after a long exposure to similar and maybe imperfect alternatives
+books will get appreciated.
+
+For instance speaking of \quotation {automated typesetting} assumes that one
+knows what typesetting is and also is aware that automated has some benefits. A
+simple \quotation {it's an \XML\ to \PDF\ converter} might work better but that
+assumes \XML\ being used which for instance not always makes sense. And while
+hyphenation, fancy font support and proper justification might impress a \TEX\
+user it often is less of an argument than one thinks.
+
+The \quotation {Why don't you} also can be heard in the \TEX\ community. In the
+worst case it's accompanied by a \quotation {\unknown\ because everybody uses
+\unknown} which of course makes no sense because you can bet that the same user
+will not fall for that argument when it comes to using an operating system or so.
+Also from outside the community there is pressure to use something else: one can
+find defense of minimal markup over \TEX\ markup or even \HTML\ markup as better
+alternative for dissemination than for instance \PDF\ or \TEX\ sources. The
+problem here is that old||timers can reflect on how relatively wonderful a
+current technique really is, given changes over time, but who wants to listen to
+an old|-|timer. Progress is needed and stimulating (which doesn't mean that all
+old technology is obsolete). When I watched Endre eNerd's \quotation {The Time
+Capsule} blu|-|ray I noticed an Ensoniq Fizmo keyboard and looked up what it was.
+I ended up in interesting reads where the bottom line was \quotation {Either you
+get it or you don't}. Reading the threads rang a bell. As with \TEX, you cannot
+decide after a quick test or even a few hours if you (get the concept and) like
+it or not: you need days, weeks, or maybe even months, and some actually never
+really get it after years.
+
+\starttheme
+    It is good to wonder why you use some program but what gets used by others
+    depends on understanding. If we can't explain the benefits there is no
+    future for \TEX. Or more exact: if it no longer provide benefits, it will
+    just disappear. Just walk around a gallery in a science museum that deals
+    with computers: it can be a bit pathetic experience.

+\startchapter[title={Why use \TEX ?}]
+
+\startsection[title={Introduction}]
+
+Let's assume that you know what \TEX\ is: a program that interprets a language
+with the same name that makes it possible to convert (tagged) input into for
+instance \PDF. For many of its users it is a black box: you key in some text, hit
+a button and get some typeset result in return. After a while you start tweaking
+this black box, meet other users (on the web), become more fluent and stick to it
+forever.
+
+But now let's assume that you don't know \TEX\ and are in search of a system
+that helps you create beautiful documents in an efficient way. When your
+documents have a complex structure you are probably willing to spend some time on
+figuring out what the best tool is. Even if a search lets you end up with
+something called \TEX, a three letter word with a dropped E, you still don't
+know what it is. Advertisement for \TEX\ is often pretty weak. It's rather easy
+to point to the numerous documents that can be found on the web. But what exactly
+does \TEX\ do and what are its benefits? In order to answer this we need to know
+who you are: an author, editor, an organization that deals with documents or needs
+to generate readable output, like publishers do.
+
+\stopsection
+
+\startsection[title={Authors}]
+
+We start with authors. Students of sciences that use mathematics don't have much
+of a choice. But most of these documents hardly communicate the message that
+\quotation {Everyone should use \TEX.} or that \quotation {All documents produced
+by \TEX\ look great.} but they do advocate that for rendering math it is a pretty
+good system. The source code of these documents often look rather messy and
+unattractive and for a non|-|math user it can be intimidating. Choosing some
+lightweight click|-|and|-|ping alternative looks attractive.
+lightweight click|-|and|-|ping alternative looks attractive.
+
+Making \TEX\ popular is not going to happen by convincing those who have to write
+an occasional letter or report. They should just use whatever suits them. On the
+other hand if you love consistency, long term support, need math, are dealing
+with a rare language or script, like to reuse content, prefer different styling
+from one source, use one source for multiple documents, or maybe love open source
+tools, then you are a candidate. Of course there is a learning curve but normally
+you can master \TEX\ rather fast and once you get the hang of it there's often no
+way back. But you always need to invest a bit beforehand.
+
+So what authors are candidates for \TEX ? It could be that \TEX\ is the only tool
+that does the job. If so, you probably learned that from someone who saw you
+struggle or had the same experience and wrote or talked about it somewhere. In
+that case using \TEX\ for creating just one document (like a thesis) makes sense.
+Otherwise, you should really wonder if you want to invest time in a tool that you
+probably have to ditch later on as most organizations stick to standard
+(commercial) word processing tools.
+
+Talking to customers we are often surprised that people have heard about \TEX, or
+even used it for a few documents in college. Some universities just prescribe the
+use of \TEX\ for reporting, so not much of a choice there. Memories are normally
+rather positive in the sense that they know that it can do the job and that it's
+flexible.
+
+User group journals, presentations at \TEX\ meetings, journals, books and manuals
+that come with \TEX\ macro packages can all be used to determine if this tool
+suits an author. Actually, I started using \TEX\ because the original \TEX book
+had some magic, and reading it was just that: reading it, as I had no running
+implementation. A few years later, when I had to write (evolving) reports, I
+picked up again. But I'm not a typical user.
+
+\stopsection
+
+\startsection[title={Programmers}]
+
+When you are a programmer who has to generate reports, for instance in \PDF, or
+write manuals, then \TEX\ can really be beneficial. Of course \TEX\ is not always
+an obvious choice, but if you're a bit able to use it it's hard to beat in
+quality, flexibility and efficiency. I'm often surprised that companies are
+willing to pay a fortune for functionality that basically comes for free.
+Programmers are accustomed to running commands and working in a code editor with
+syntax highlighting so that helps too. They too recognize when something can be
+done more efficiently.
+
+When you need to go from some kind of input (document source, database,
+generated) to some rendered output there currently are a few endpoints: a
+(dynamic) \HTML\ page, a \PDF\ document, something useable in a word processor,
+or a representation using the desktop user interface. It's the second category
+where \TEX\ is hard to beat but even using \TEX\ and \METAPOST\ for creating a
+chart can make sense.
+
+There are of course special cases where \TEX\ fits in nicely. Say that you have
+to combine \PDF\ documents. There are numerous tools to do that and \TEX\ is one.
+The advantage of \TEX\ over other tools is that it's trivial to add additional
+text, number pages, provide headers and footers. And it will work forever. Why?
+Because \TEX\ has been around for decades and will be around for decades to come.
+It's an independent component. The problem with choosing for \TEX\ is that the
+starting point is important. The question is not \quotation {What tool should I
+use?} but \quotation {What problem do I need to solve?}. An open discussion about
+the objectives and possibilities is needed, not some checklist based on
+assumptions. If you don't know \TEX\ and have never worked with a programmable
+typesetting environment, you probably don't see the possibilities. In fact, you
+might even choose for \TEX\ for the wrong reasons.
+
+The problem with this category of users is that they seldom have the freedom to
+choose their tools. There are not that many jobs where the management is able to
+recognize the clever programmer who can determine that \TEX\ is suitable for a
+lot of jobs and can save money and time. Even the long term availability and
+support is not an argument since not only most tools (or even apis) changes every
+few years but also organizations themselves change ownership, objectives, and
+personnel on a whim. The concept of \quote {long term} is hard to grasp for most
+people (just look at politics) and it's only in retrospect that one can say
+\quote {We used that toolkit for over a decade.}
+
+\stopsection
+
+\startsection[title={Organizations}]
+
+Authors (often) have the advantage that they can choose themselves: they can use
+what they like. In practice any decent programmer is able to find the suitable
+tools but convincing the management to use one of them can be a challenge. Here
+we're also talking of \quote {comfort zones}: you have to like a tool(chain).
+Organizations normally don't look for \TEX. Special departments are responsible
+for choosing and negotiating whatever is used in a company. Unfortunately
+companies don't always start from the open question \quotation {We have this
+problem, we want to go there, what should we do?} and then discuss options with
+for instance those who know \TEX. Instead requirements are formulated and matches
+are found. The question then is \quotation {Are these requirements cut in stone?}
+and if not (read: we just omit some requirements when most alternatives don't
+meet them), were other requirements forgotten? Therefore organizations can end up
+with the wrong choice (using \TEX\ in a situation where it makes no sense) or
+don't see opportunities (not using \TEX\ while it makes most sense). It doesn't
+help that a hybrid solution (use a mix of \TEX\ and other tools) is often not an
+option. Where an author can just stop using a tool after a few days of
+disappointment, and where a programmer can play around a bit before making a
+choice, an organization probably best can start small with a proof of concept.
+
+Let's take a use case. A publisher wants to automatically convert \XML\ files
+into \PDF. One product can come from multiple sources (we have cases where
+thousands of small \XML\ files combine into one final product). Say that we have
+three different layouts: a theory book, a teachers manual and an answer book. In
+addition special proofing documents have to be rendered. The products might be
+produced on demand with different topics in any combination. There is at least
+one image and table per page, but there can be more. There are color and
+backgrounds used, tables of contents generated, there is extensive cross
+referencing and an index. Of course there is math.
+
+Now let's assume an initial setup costs 20K Euro and, what happens often when the
+real products show up, a revision after one year takes the same amount. We also
+assume 10K for the following eight years for support. So, we end up with 120K
+over 10 years. If one goes cheap we can consider half of that, or we can be
+pessimistic and double the amount.
+
+The first year 10K pages are produced, the second year 20K and after that 30K per
+year. So, we're talking of 270K pages. If we include customer specific documents
+and proofing we might as well end up with a multiple of that.
+
+So, we have 120K Euro divided by 270K pages or about half an Euro per page. But
+likely we have more pages so it costs less. If we double the costs then we can
+assume that some major changes took place which means more pages. In fact we had
+projects where the layout changed, all documents were regenerated and the costs
+were included in the revision, so far from double. We also see many more pages
+being generated so in practice the price per page drops below half an Euro. The
+more we process the cheaper it gets and one server can produce a lot of pages!
+
+Now, the interesting bit of such a calculation is that the costs only concern the
+hours spent on a solution. A \TEX\ based system comes for free and there are no
+license costs. Whatever alternative is taken, even if it is as flexible, it will
+involve additional costs. From the perspective of costs it's very hard to beat
+\TEX. Add to that the possibility for custom extensions, long term usage and the
+fact that one can adapt the system. The main question of course is: does it do
+the job. The only way to find out is to either experiment (which is free),
+consult an expert (not free, but then needed anyway for any solution) or ask an
+expert to make a proof of concept (also not free but relatively cheap and
+definitely cheaper than a failure). In fact, before making decisions about what
+solution is best it might be a good idea to check with an expert anyway, because
+more or less than one thinks might be possible. Also, take into account that the
+\TEX\ ecosystem is often one of the first to support new technologies, and
+normally does that within its existing interface. And there is plenty of free
+support and knowledge available once you know how to find it. Instead of wasting
+time and money on advertisement and fancy websites, effort goes into support and
+development. Even if you doubt that the current provider is around in the decade
+to come, you can be sure that there will be others, simply because \TEX\ attracts
+people. Okay, it doesn't help that large companies like to out source to
+far||far||away and expect support around the corner, so in the end they might
+kill their support chain.
+
+When talking of \TEX\ used in organizations we tend to think of publishers. But
+this is only a small subset of organizations where information gets transformed
+into something presentable. For small organizations the choice for \TEX\ can be
+easy: costs, long term stability, knowing some experts are driving forces. For
+large organizations these factors seem (at least to us) hardly relevant. We've
+(had) projects where actually the choice for using a \TEX\ based solution was (in
+retrospect) a negative one: there was no other tool than this relatively unknown
+thing called \TEX. Or, because the normal tools could not be used, one ended up
+with a solution where (behind the scenes) \TEX\ is used, without the organization
+knowing it. Or, it happened that the problem at hand was mostly one that demands
+in|-|depth knowledge of manipulating content, cleaning up messy data, combining
+resources (images or \PDF\ documents), all things that happen to be available in
+the perspective of \TEX. If you can solve a hard to solve problem for them then
+an organization doesn't care what tool you use. What does matter is that the
+solution runs forever, that costs are controllable and above all, that it
+\quotation {Just works.} And if you can make it work fast, that helps too. We
+can safely claim that when \TEX\ is evaluated as being a good option, that in the
+end it always works out quite well.
+
+Among arguments that (large) organizations like to use against a choice for \TEX\
+(or something comparable) are the size of the company that they buy their
+solution from, the expected availability for support, and the wide|-|spread usage
+of the tool at hand. One can wonder if it also matters that many vendors change
+ownership, change products every few years, change license conditions when they
+like, charge a lot for support or just abort a tool chain. Unfortunately when that
+happens those responsible for choosing such a system can have moved on to another
+job, so this is seldom part of an evaluation. For the supplier the other side of
+the table is just as much of a gamble. In that respect, an organization that
+wants to use an open source (and|/|or free) solution should realize that getting
+a return on investment on such a development is pretty hard to achieve. So, who
+really takes the risk for writing open source?
+
+For us, the reason to develop \CONTEXT\ and make it open is that it fits in our
+philosophy and we like the community. It is actually not really giving us an
+advantage commercially: it costs way more to develop, support and keep
+up|-|to|-|date than it will ever return. We can come up with better, faster and
+easier solutions and in the end we pay the price because it takes less time to
+cook up styles. So there is some backslash involved because commercially a
+difficult solution leads to more billable hours. Luckily we tend to avoid wasting
+time so we improve when possible and then it ends up in the distributed code.
+And, once the solution is there, anyone can use it. Basically also for us it's
+just a tool, like the operating system, editor and viewer are. So, what keep
+development going is mostly the interaction with the community. This also means
+that a customer can't really demand functionality for free: either wait for it to
+show up or pay for it (which seldom happens). Open source is not equivalent with
+\quotation {You get immediately what you want because someone out there writes
+the code.}. There has to be a valid reason and often it's just users and meetings
+or just some challenge that drives it.
+
+This being said, it is hard to convince a company to use \TEX. It has to come
+from users in the organization. Or, what we sometimes see with publishers, it
+comes with an author team or acquired product line where it's the only option.
+Even then we seldom see transfer to other branches in the organizations. No one
+seems to wonder \quotation {How on earth can that \XML\ to \PDF\ project produce
+whatever output in large quantities in a short period of time} while other (past)
+projects failed. It probably relates to the abstraction of the process. Even
+among \TEX\ users it can be that you demonstrate something with a click on a
+button and that many years afterwards someone present at that moment tells you
+that they just discovered that this or that can be done by hitting a button. I'm
+not claiming that \TEX\ is the magic wand for everything but in some areas it's
+pretty much ahead of the pack. Go to a \TEX\ user meeting and you will be surprised
+about the accumulated diverse knowledge present in the room. It's user demand that
+drives \CONTEXT\ development, not commerce.
+
+\stopsection
+
+\startsection[title={Choosing}]
+
+So, where can one find information about \TEX\ and friends? On the web
+one has to use the right search keys, so adding \type {tex} helps: \typ {context
+tex} or \typ {xml tex pdf} and so on. Can one make a fancy hip website, sure, but
+it being a life|-|long, already old and mature environment, and given that it
+comes for free, or is used low|-|budget, not much effort and money can be spent
+on advertising it. A benefit is that no false promises and hypes are made either.
+If you want to know more, just ask the right folks.
+
+For all kind of topics one can find interesting videos and blogs. One can
+subscribe to channels on YouTube or join forums. Unfortunately not that many
+bloggers or vloggers or podcasters come up with original material every time, and
+often one starts to recognize patterns and will get boring by repetition of wisdom
+and arguments. The same is true for manuals. Is a ten year old manual really
+obsolete? Should we just recompile it to fake an update while in fact there has
+been no need for it? Should we post twenty similar presentations while one can
+do? (If one already wants to present the same topic twenty times in the first
+place?) Maybe one should compare \TEX\ with cars: they became better over time
+and can last for decades. And no new user manual is needed.
+
+As with blogs and vlogs advertising \TEX\ carries the danger for triggering
+political discussions and drawing people into discussions that are not pleasant:
+\TEX\ versus some word processor, open versus closed source, free versus paid
+software, this versus that operating system, editor such or editor so.
+
+To summarize, it's not that trivial to come up with interesting information about
+\TEX, unless one goes into details that are beyond the average user. And those
+who are involved are often involved for a long time so it gets more complex over
+time. User group journals that started with tutorials later on became expert
+platforms. This is a side effect of being an old and long|-|term toolkit. If
+you run into it, and wonder if it can serve your purpose, just ask an expert.
+
+Most \TEX\ solutions are open source and come for free as well. Of course if you
+want a specific solution or want support beyond what is offered on mailing lists
+and forums you should be willing to pay for the hours spent. For a professional
+publisher (of whatever kind) this is not a problem, if only because any other
+solution also will cost something. It is hard to come up with a general estimate.
+A popular measure of typesetting costs is the price per page, which can range
+from a couple of euro's per page to two digit numbers. We've heard of cases where
+initial setup costs were charged. If not much manual intervention is needed a
+\TEX\ solution mostly concerns initial costs.
+
+Let's return to the main question \quotation {Why use \TEX ?} in which you can
+replace \TEX\ by one of the macro packages build on top of it, for instance
+\CONTEXT. If an (somewhat older) organization considers using \TEX\ it should
+also ask itself, why it wasn't considered long ago already? For sure there have
+been developments in \TEX\ engines (in \CONTEXT\ we use \LUATEX) as well as
+possibilities of macro packages but if you look at the documents produced with
+them, there is not that much difference with decades ago. Processing has become
+faster, some things have become easier, but new technologies have always been
+supported as soon at they showed up. Advertising is often just repeating an old
+message.
+
+The \TEX\ ecosystem was among the first in supporting for instance \OPENTYPE, and
+the community even made sure that there were free fonts available. A format like
+\PDF\ was supported as soon as it shows up and \TEX\ was the first to demonstrate
+what advanced features were there and how way it was to adapt to changes.
+Processing \XML\ using \TEX\ has never been a big deal and if that is a reason to
+look at this already old and mature technology, then an organization can wonder
+if years and opportunities (for instance for publishing on demand or easy
+updating of manuals) have been lost. Of course there are (and have been)
+alternative tools but the arguments for using \TEX\ or not are not much different
+now. It can be bad marketing of open and free software. It can be that \TEX\ has
+been around too long. It can also be that its message was not understood yet. On
+the other hand, in software development it's quite common to reinvent wheels and
+present old as new. It's never to late to catch on.

+\startchapter[title={Getting there, version 1.10}]
+
+When we decided to turn experiments with a \LUA\ extensions to \PDFTEX\ into
+developing \LUATEX\ as alternative engine we had, in addition to opening up some
+of \TEX's internals, some extensions in mind. Around version 1.00 most was
+already achieved and with version 1.10 we're pretty close to where we want to be.
+The question is, when are we ready? In order to answer that I will look at four
+aspects:
+
+\startitemize[packed]
+\startitem objectives \stopitem
+\startitem functionality \stopitem
+\startitem performance \stopitem
+\startitem stability \stopitem
+\stopitemize
+
+The main {\em objective} was to open up \TEX\ in a way that permit extensions
+without the need to patch the engine. Although it might suit us, we don't want to
+change too much the internals, first of all because \TEX\ is \TEX, the documented
+program with a large legacy. \footnote {This is reflected in the keywords that
+exposed mechanisms use: they reflect internal variable names and constants and as
+a consequence there is inconsistency there.} Discussions about how to extend
+\TEX\ are not easy and seldom lead to an agreement so better is to provide a way
+to do what you like without bothering other users and|/|or interfering with macro
+packages. I think that this objective is met quite well now. Other objectives,
+like embedding basic graphic capabilities using \METAPOST\ have already been met
+long ago. There is more control over the backend and modern fonts can be dealt
+with.
+
+The {\em functionality} in terms of primitives has been extended but within
+reasonable bounds: we only added things that make coding a bit more natural but
+we realize that this is very subjective. So, here again we can say that we met
+our goals. A lot can be achieved via \LUA\ code and users and developers need to
+get accustomed to that if they want to move on with \LUATEX. We will not
+introduce features that get added to or are part of other engines.
+
+We wanted to keeping {\em performance} acceptable. The core \TEX\ engine is
+already pretty fast and it's often the implementation of macros (in macro
+packages) that creates a performance hit. Going \UTF\ has a price as do modern
+fonts. At the time of this writing processing the 270 page \LUATEX\ manual takes
+about 12 seconds (one run), which boils down to over 27 pages per second.
+

+\BC \LUAJITTEX \NC $ 9.7$  \NC $+0.5$   \NC \NR
+\stoptabulate
+
+Is this fast or slow? One can do tests with specific improvements (using new
+primitives) but in practice it's very hard to improve performance significantly.
+This is because a test with millions of calls that show a .05 second improvement
+disappears when one only has a few thousand calls. Many small improvements can
+add up, but less that one thinks, especially when macros are already quite
+optimal. Also this runtime includes time normally used for running additional
+programs (e.g.\ for getting bibliographies right).
+
+It must be said that performance is not completely under our control. For
+instance, we have patched the \LUAJIT\ hash function because it favours \URL's
+and therefore favours hashing the middle of the string which is bad for our use
+as we are more interested in the (often unique) start of strings. We also
+compress the format which speeds up loading but not on the native windows 64~bit
+binary. At the time this writing the extra overhead is 2~seconds due to some
+suboptimal gzip handling; the cross compiled 64~bit mingw binaries that I use
+don't suffer from this. When I was testing the 32~bit binaries on the machine of
+a colleague, I was surprised to measure the following differences on a complex
+document with hundreds of \XML\ files, many images and a lot of manipulations.
+
+\starttabulate[||c|c|]

+\BC \LUATEX    \NC $21.5$              \NC $15.2$              \NC \NR
+\BC \LUAJITTEX \NC $10.7$              \NC $10.3$              \NC \NR
+\stoptabulate
+
+Now, these are just rough numbers but they demonstrate that the gap between
+\LUATEX\ and \LUAJITTEX\ is becoming less which is good because at this moment it
+looks like \LUAJIT\ will not catch up with \LUA\ 5.3 so at some point we might
+drop it. It will be interesting to see what \LUA\ 5.4 will bring as it offers an
+\ alternative garbage collector. And imagine that the regular \LUA\ virtual
+machine gets more optimized.
+
+You also have to take into account that having a browser open in the background
+of a \TEX\ run has way more impact than a few tenths of a second in \LUATEX\
+performance. The same is true for memory usage: why bother about \LUATEX\ taking
+tens of megabytes for fonts while a few tabs in a browser can bump memory
+consumption to gigabytes of memory usage. Also, using a large \TEX\ tree (say the
+whole of \TEXLIVE) can have a bit of a performance hit! Or what about inefficient
+callbacks, using inefficient \LUA\ code of badly designed solutions? What we
+could gain here we loose there, so I think we can safely say that the current
+implementation of \LUATEX\ is as good as you can (and will) get. Why should we
+introduce obscure optimizations where on workstations \TEX\ is just one of the
+many processes? Why should we bother too much to speed up on servers that have
+start|-|up or job management overhead or are connected to relatively slow remote
+file system? Why squeeze out a few more milliseconds when badly written macros or
+styles can have an way more impact on performance? So, for now we're satisfied
+with performance. Just for the record, the ratio between \CONTEXT\ \MKII\
+running other engines and \LUATEX\ with \MKIV\ for the next snippet of code:
+
+\starttyping
+\dorecurse{250}{\input tufte\par}
+\stoptyping
+
+is 2.8 seconds for \XETEX, 1.5 seconds for \LUATEX, 1.2 seconds for \LUAJITTEX,
+and 0.9 seconds for \PDFTEX. Of course this is not really a practical test but it
+demonstrates the baseline performance on just text. The 64 bit version of \PDFTEX\
+is actually quite a bit slower on my machine. Anyway, \LUATEX\ (1.09) with \MKIV\
+is doing okey here.
+
+That brings us to {\em stability}. In order to achieve that we will not introduce
+many more extensions. That way users get accustomed to what is there (read: there
+is no need to search for what else is possible). Also, it makes that existing
+functionality can become bug free because no new features can interfere. So, at
+some point we have to decide that this is it. If we can do what we want now,
+there are no strong arguments for more. in that perspective version 1.10 can be
+considered very close to what we want to achieve.
+
+Of course development will continue. For instance, the \PDF\ inclusion code will
+be replaced by more lightweight and independent code. Names of functions and
+symbolic constants might be normalized (as mentioned, currently they are often
+related to or derived from internals). More documentation will be added. We will
+quite probably keep up with \LUA\ versions. Also the \FFI\ interface will become
+more stable. And for sure bugs will be fixed. We might add a few more options to
+control behaviour of for instance of math rendering. Some tricky internals (like
+alignments) might get better attribute support if possible. But currently we
+think that most fundamental issues have been dealt with.

+\startchapter[title={From \LUA\ 5.2 to 5.3}]
+
+When we started with \LUATEX\ we used \LUA\ 5.1 and moved to 5.2 when that became
+available. We didn't run into issues then because there were no fundamental
+changes that could not be dealt with. However, when \LUA\ 5.3 was announced in
+2015 we were not sure if we should make the move. The main reason was that we'd
+chosen \LUA\ because of its clean design which meant that we had only one number
+type: double. In 5.3 on the other hand, deep down a number can be either an
+integer or a floating point quantity.
+
+Internally \TEX\ is mostly (up to) 32-bit integers and when we go from \LUA\ to
+\TEX\ we round numbers. Nonetheless one can expect some benefits in using
+integers. Performance|-|wise we didn't expect much, and memory consumption would
+be the same too. So, the main question then was: can we get the same output and
+not run into trouble due to possible differences in serializing numbers; after
+all \TEX\ is about stability. The serialization aspect is for instance important
+when we compare quantities and|/|or use numbers in hashes.
+
+Apart from this change in number model, which comes with a few extra helpers,
+another extension in 5.3 was that bit|-|wise operations are now part of the
+language. The lpeg library is still not part of stock \LUA. There is some minimal
+\UTF8 support, but less than we provide in \LUATEX\ already. So, looking at these
+changes, we were not in a hurry to update. Also, it made sense to wait till this
+important number|-|related change was stable.
+
+But, a few years later, we still had it on our agenda to test, and after the
+\CONTEXT\ 2017 meeting we decided to give it a try; here are some observations. A
+quick test was just dropping in the new \LUA\ code and seeing if we could make a
+\CONTEXT\ format. Indeed that was no big deal but a test run failed because at
+some point a (for instance) \type {1} became a \type {1.0}. It turned out that
+serializing has some side effects. And with some ad hoc prints for tracing (in
+the \LUATEX\ source) I could figure out what went on. How numbers are seen can
+(to some extent) be deduced from the \type {string.format} function, which is in
+\LUA\ a combination of parsing, splitting and concatenation combined with piping
+to the \CCODE\ \type {sprintf} function. \footnote {Actually, at some point I
+decided to write my own formatter on top of \type {format} and I ended up with
+splitting as well. It's only now that I realize why this is working out so well
+(in terms of performance): simple format (single items) are passed more or less
+directly to \type {sprintf} and as \LUA\ itself is fast, due to some caching, the
+overhead is small compared to the built|-|in splitter method. And the \CONTEXT\
+formatter has many more options and is extensible.}
+

+
+This demonstrates that we have to be careful when we need these numbers
+represented as strings. In \CONTEXT\ the number of places where we had to check
+for that was not that large; in fact, only some hashing related to font sizes had
+to be done using explicit rounding.
+
+Another surprising side effect is the following. Instead of:
+
+\starttyping
+local n = 2^6
+\stoptyping
+
+we now need to use:
+
+\starttyping
+local n = 0x40
+\stoptyping
+
+or just:
+
+\starttyping
+local n = 64
+\stoptyping
+
+because we don't want this to be serialized to \type {64.0} which is due to the
+fact that a power results in a float. One can wonder if this makes sense when we
+apply it to an integer.
+
+At any rate, once we could process a file, two documents were chosen for a
+performance test. Some experiments with loops and casts had demonstrated that we
+could expect a small performance hit and indeed, this was the case. Processing
+the \LUATEX\ manual takes 10.7 seconds with 5.2 on my 5-year-old laptop and 11.6
+seconds with 5.3. If we consider that \CONTEXT\ spends 50\% of its time in \LUA,
+then we see a 20\% performance penalty. Processing the \METAFUN\ manual (which
+has lots of \METAPOST\ images) went from less than 20 seconds (\LUAJITTEX\ does
+it in 16 seconds) up to more than 27 seconds. So there we lose more than 50\% on
+the \LUA\ end. When we observed these kinds of differences, Luigi and I
+immediately got into debugging mode, partly out of curiosity, but also because
+consistent performance is important to~us.
+
+Because these numbers made no sense, we traced different sub-mechanisms and
+eventually it became clear that the reason for the speed penalty was that the
+core \typ {string.format} function was behaving quite badly in the \type {mingw}
+cross-compiled binary, as seen by this test:
+
+\starttyping
+local t = os.clock()
+for i=1,1000*1000 do
+ -- local a = string.format("%.3f",1.23)
+ -- local b = string.format("%i",123)
+    local c = string.format("%s",123)
+end
+print(os.clock()-t)
+\stoptyping
+

+\stoptabulate
+
+The 5.2 binaries perform the same but the 5.3 Lua binary greatly outperforms
+\LUATEX, and so we had to figure out why. After all, all this integer
+optimization could bring some gain! It took us a while to figure this out. The
+numbers in parentheses are the results after fixing this.
+
+Because font internals are specified in integers one would expect a gain
+in running:
+
+\starttyping
+mtxrun --script font --reload force
+\stoptyping
+
+and indeed that is the case. On my machine a scan results in 2561 registered
+fonts from 4906 read files and with 5.2 that takes 9.1 seconds while 5.3 needs a
+bit less: 8.6 seconds (with the bad format performance) and even less once that
+was fixed. For a test:
+
+\starttyping
+\setupbodyfont[modern]     \tf \bf \it \bs
+\setupbodyfont[pagella]    \tf \bf \it \bs
+\setupbodyfont[dejavu]     \tf \bf \it \bs
+\setupbodyfont[termes]     \tf \bf \it \bs
+\setupbodyfont[cambria]    \tf \bf \it \bs
+\starttext \stoptext
+\stoptyping
+
+This code needs 30\% more runtime so the question is: how often do we call \type
+{string.format} there? A first run (when we wipe the font cache) needs some
+715,000 calls while successive runs need 115,000 calls so that slow down
+definitely comes from the bad handling of \type {string.format}. When we drop in
+a \LUA\ update or whatever other dependency we don't want this kind of impact. In
+fact, when one uses external libraries that are or can be compiled under the
+\TEX\ Live infrastructure and the impact would be such, it's bad advertising,
+especially when one considers the occasional complaint about \LUATEX\ being
+slower than other engines.
+
+The good news is that eventually Luigi was able to nail down this issue and we
+got a binary that performed well. It looks like \LUA\ 5.3.4 (cross|)|compiles
+badly with \GCC\ 5.3.0 and 6.3.0.
+
+So in the end caching the fonts takes:
+
+\starttabulate[||c|c|]
+\BC            \BC caching   \BC running \NC \NR
+\BC 5.2 stock  \NC  8.3      \NC 1.2     \NC \NR
+\BC 5.3 bugged \NC 12.6      \NC 2.1     \NC \NR
+\BC 5.3 fixed  \NC  6.3      \NC 1.0     \NC \NR
+\stoptabulate
+
+So indeed it looks like 5.3 is able to speed up \LUATEX\ a bit, given that one
+integrates it in the right way! Using a recent compiler is needed too, although
+one can wonder when a bad case will show up again. One can also wonder why such a
+slow down can mostly go unnoticed, because for sure \LUATEX\ is not the only

+
+So, to summarize the process. A quick test was relatively easy: move 5.3 into the
+code base, adapt a little bit of internals (there were some \LUATEX\ interfacing
+bits where explicit rounding was needed), run tests and eventually fix some
+issues related to the Makefile (compatibility) and \CCODE\ obscurities (the slow
+\type {sprintf}). Adapting \CONTEXT\ was also not much work, and the test suite
+uncovered some nasty side effects. For instance, the valid 5.2 solution:
+
+\starttyping
+local s = string.format("02X",u/1024)
+local s = string.char        (u/1024)
+\stoptyping
+
+now has to become (both 5.2 and 5.3):
+
+\starttyping
+local s = string.format("02X",math.floor(u/1024))
+local s = string.char        (math.floor(u/1024))
+\stoptyping
+
+or (both 5.2 and (emulated or real) 5.3):
+
+\starttyping
+local s = string.format("02X",bit32.rshift(u,10))
+local s = string.char        (bit32.rshift(u,10))
+\stoptyping
+
+or (only 5.3):
+
+\starttyping
+local s = string.format("02X",u >> 10))
+local s = string.char        (u >> 10)
+\stoptyping
+
+or (only 5.3):
+
+\starttyping
+local s = string.format("02X",u//1024)
+local s = string.char        (u//1024)
+\stoptyping
+
+A conditional section like:
+
+\starttyping
+if LUAVERSION >= 5.3 then
+    local s = string.format("02X",u >> 10))
+    local s = string.char        (u >> 10)
+else
+    local s = string.format("02X",bit32.rshift(u,10))
+    local s = string.char        (bit32.rshift(u,10))
+end
+\stoptyping
+
+will fail because (of course) the 5.2 parser doesn't like that. In \CONTEXT\ we
+have some experimental solutions for that but that is beyond this summary.
+
+In the process a few \UTF\ helpers were added to the string library so that we
+have a common set for \LUAJIT\ and \LUA\ (the \type {utf8} library that was added
+to 5.3 is not that important for \LUATEX). For now we keep the \type {bit32}
+library on board. Of course we'll not mention all the details here.
+
+When we consider a gain in speed of 5-10\% with 5.3 that also means that the gain
+of \LUAJITTEX\ compared to 5.2 becomes less. For instance in font processing both
+engines now perform closer to the same.
+
+As I write this, we've just entered 2018 and after a few months of testing
+\LUATEX\ with \LUA\ 5.3 we're confident that we can move the code to the
+experimental branch. This means that we will use this version in the \CONTEXT\
+distribution and likely will ship this version as 1.10 in 2019, where it becomes
+the default. The 2018 version of \TEX~Live will have 1.07 with \LUA\ 5.2 while
+intermediate versions of the \LUA\ 5.3 binary will end up on the \CONTEXT\
+garden, probably with number 1.08 and 1.09 (who knows what else we will add or
+change in the meantime).

+Much of the \LUA\ code in \CONTEXT\ originates from experiments. When it survives
+in the source code it is probably used, waiting to be used or kept for
+educational purposes. The functionality that we describe here has already been
+present for a while in \CONTEXT, but improved a little starting with \LUATEX\
+1.08 due to an extra helper. The code shown here is generic and not used in
+\CONTEXT\ as such.
+
+Say that we have this code:
+
+\startbuffer
+for i=1,10000 do
+    tex.sprint("1")
+    tex.sprint("2")
+    for i=1,3 do
+        tex.sprint("3")
+        tex.sprint("4")

+    end
+    tex.sprint("\\space")
+end
+\stopbuffer
+
+\typebuffer
+
+% \ctxluabuffer
+
+When we call \type {\directlua} with this snippet we get some 30 pages of \type
+{12345345345}. The printed text is saved till the end of the \LUA\ call, so
+basically we pipe some 170.000 characters to \TEX\ that get interpreted as one
+paragraph.
+
+Now imagine this:
+
+\startbuffer
+\setbox0\hbox{xxxxxxxxxxx} \number\wd0
+\stopbuffer
+
+\typebuffer
+
+which gives \getbuffer. If we check the box in \LUA, with:
+
+\startbuffer
+tex.sprint(tex.box[0].width)
+tex.sprint("\\enspace")
+tex.sprint("\\setbox0\\hbox{!}")
+tex.sprint(tex.box[0].width)
+\stopbuffer
+
+\typebuffer
+
+the result is {\tttf \ctxluabuffer}, which is not what you would expect at first
+sight. However, if you consider that we just pipe to a \TEX\ buffer that gets
+parsed after the \LUA\ call, it will be clear that the reported width is the
+width that we started with. It will work all right if we say:
+
+\startbuffer
+tex.sprint(tex.box[0].width)
+tex.sprint("\\enspace")
+tex.sprint("\\setbox0\\hbox{!}")
+tex.sprint("\\directlua{tex.sprint(tex.box[0].width)}")
+\stopbuffer
+
+\typebuffer
+
+because now we get: {\tttf\ctxluabuffer}. It's not that complex to write some
+support code that makes this more convenient. This can work out quite well but
+there is a drawback. If we use this code:
+
+\startbuffer
+print(status.input_ptr)
+tex.sprint(tex.box[0].width)
+tex.sprint("\\enspace")
+tex.sprint("\\setbox0\\hbox{!}")
+tex.sprint("\\directlua{print(status.input_ptr)\
+    tex.sprint(tex.box[0].width)}")
+\stopbuffer
+
+\typebuffer
+
+Here we get \type {6} and \type {7} reported. You can imagine that when a lot of
+nested \type {\directlua} calls happen, we can get an overflow of the input level
+or (depending on what we do) the input stack size. Ideally we want to do a \LUA\
+call, temporarily go to \TEX, return to \LUA, etc.\ without needing to worry
+about nesting and possible crashes due to \LUA\ itself running into problems. One
+charming solution is to use so|-|called coroutines: independent \LUA\ threads
+that one can switch between --- you jump out from the current routine to another
+and from there back to the current one. However, when we use \type {\directlua}
+for that, we still have this nesting issue and what is worse, we keep nesting
+function calls too. This can be compared to:
+
+\starttyping
+\def\whatever{\ifdone\whatever\fi}
+\stoptyping
+
+where at some point \type {\ifdone} is false so we quit. But we keep nesting when
+the condition is met, so eventually we can end up with some nesting related
+overflow. The following:
+
+\starttyping
+\def\whatever{\ifdone\expandafter\whatever\fi}
+\stoptyping
+
+is less likely to overflow because there we have tail recursion which basically
+boils down to not nesting but continuing. Do we have something similar in
+\LUATEX\ for \LUA ? Yes, we do. We can register a function, for instance:
+
+\starttyping
+lua.get_functions_table()[1] = function() print("Hi there!") end
+\stoptyping
+
+and call that one with:
+
+\starttyping
+\luafunction 1
+\stoptyping
+
+This is a bit faster than calling a function like:
+
+\starttyping
+\directlua{HiThere()}
+\stoptyping
+
+which can also be achieved by
+
+\starttyping
+\directlua{print("Hi there!")}
+\stoptyping
+
+which sometimes can be more convenient. Anyway, a function call is what we can
+use for our purpose as it doesn't involve interpretation and effectively behaves
+like a tail call. The following snippet shows what we have in mind:
+
+\startbuffer[code]

+\typebuffer[demo]
+
+We do create coroutines, go back and forwards between \LUA\ and \TEX, but avoid
+memory being filled up with printed content. If we flush paragraphs (instead of
+e.g.\ the space) then the main difference is that instead of a small delay due to
+the loop unfolding in a large set of prints and accumulated content, we now get a
+steady flushing and processing.
+
+However, we can still have an overflow of input buffers because we still nest
+them: the limitation at the \TEX\ end has moved to a limitation at the \LUA\ end.
+How come? Here is the code that we use:
+
+\typebuffer[code]
+
+The \type {routine} creates a coroutine, and \type {yield} gives control to \TEX.
+The \type {resume} is done at the \TEX\ end when we're finished there. In
+practice this works fine and when you permit enough nesting and levels in \TEX\
+then you will not easily overflow.
+
+When I picked up this side project and wondered how to get around it, it suddenly
+struck me that if we could just quit the current input level then nesting would
+not be a problem. Adding a simple helper to the engine made that possible (of
+course figuring it out took a while):
+
+\startbuffer[code]
+local stepper = nil
+local stack   = { }
+local fid     = 0xFFFFFF
+local goback  = "\\luafunction" .. fid .. "\\relax"
+
+function tex.resume()
+    if coroutine.status(stepper) == "dead" then
+        stepper = table.remove(stack)
+    end
+    if stepper then
+        coroutine.resume(stepper)
+    end
+end
+
+lua.get_functions_table()[fid] = tex.resume
+
+if texio.closeinput then
+    function tex.yield()
+        tex.sprint(goback)
+        coroutine.yield()
+        texio.closeinput()
+    end
+else
+    function tex.yield()
+        tex.sprint(goback)
+        coroutine.yield()
+    end
+end
+
+function tex.routine(f)

+\typebuffer[code]
+
+% \testfeatureonce {1} {\setbox0\hpack{\ctxluabuffer[code]}} \elapsedtime
+
+This time we need 0.12 seconds in both engines. So what if we run this:
+
+\startbuffer[code]
+\dorecurse{10000}{%
+    \setbox0\hpack{x}
+    \number\wd0
+    \dorecurse{3}{%
+        \setbox0\hpack{xx}
+        \number\wd0
+    }%
+}
+\stopbuffer
+
+\typebuffer[code]
+
+% \testfeatureonce {1} {\setbox0\hpack{\getbuffer[code]}} \elapsedtime
+
+Pure \TEX\ needs 0.30 seconds for both engines but there we lose 0.13 seconds on
+the loop code. In the \LUA\ example where we yield, the loop code takes hardly
+any time. As we need only 0.05 seconds more it demonstrates that when we use the
+power of \LUA\ the performance hit of the switch is quite small: we yield 40.000
+times! In general, such differences are far exceeded by the overhead: the time
+needed to typeset the content (which \type {\hpack} doesn't do), breaking
+paragraphs into lines, constructing pages and other overhead involved in the run.
+In \CONTEXT\ we use a slightly different variant which has 0.30 seconds more
+overhead, but that is probably true for all \LUA\ usage in \CONTEXT, but again,
+it disappears in other runtime.
+
+Here is another example:
+
+\startbuffer[code]
+\def\TestWord#1%
+  {\directlua{
+     tex.routine(function()
+       tex.sprint("\\setbox0\\hbox{\\tttf #1}")
+       tex.yield()
+       tex.sprint(math.round(100 * tex.box[0].width/tex.hsize))
+       tex.sprint(" percent of the hsize: ")
+       tex.sprint("\\box0")
+     end)
+  }}
+\stopbuffer
+
+\typebuffer[code] \getbuffer[code]
+
+\startbuffer
+The width of next word is \TestWord {inline}!
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Now, in order to stay realistic, this macro can also be defined as:
+
+\startbuffer[code]
+\def\TestWord#1%
+  {\setbox0\hbox{\tttf #1}%
+   \directlua{
+      tex.sprint(math.round(100 * tex.box[0].width/tex.hsize))
+   } %
+   percent of the hsize: \box0\relax}
+\stopbuffer
+
+\typebuffer[code]
+
+We get the same result: \quotation {\getbuffer}.
+
+We have been using a \LUA|-|\TEX\ mix for over a decade now in \CONTEXT, and have
+never really needed this mixed model. There are a few places where we could
+(have) benefitted from it and we might use it in a few places, but so far we have
+done fine without it. In fact, in most cases typesetting can be done fine at the
+\TEX\ end. It's all a matter of imagination.

+\startchapter[title={More (new) expansion trickery}]
+
+Contrary to what one might expect when looking at macro definitions, \TEX\ is
+pretty efficient. Occasionally I wonder if some extra built in functionality
+could help me write better code but when you program with a bit care there is
+often not much to gain in terms of tokens and performance. \footnote {The long
+trip to the yearly Bacho\TeX\ meeting is always a good opportunity to ponder
+\TEX\ and its features. The new functionality discussed here is a side effect of
+the most recent trip.} Also, some possible extensions probably only would be
+applied a few times which makes them low priority. When you look at the
+extensions brought by \ETEX\ the number is not that large, and \LUATEX\ only
+added a few that deal with the language, for instance \tex {expanded} which is
+like an \tex {edef} without the defining a macro and acts on a token list wrapped
+in (normally) curly braces. Just as reference we mention some of the expansion
+related helpers.
+
+\starttabulate[|l|l|p|]
+\BC command \BC argument \BC
+    comment
+\NC \NR
+\HL
+\NC \tex {expandafter} \NC \type {token} \NC
+    The token after the next token gets expanded (one level only). In tricky

+    nice puzzle.
+\NC \NR
+\NC \tex {noexpand} \NC \type {token} \NC
+    The token after this command is not expanded in the context of expansion.
+\NC \NR
+\NC \tex {expanded} \NC \type {{tokens}} \NC
+    The given token list is expanded. This command showed up early in \LUATEX\
+    development and was taken from \ETEX\ follow|-|ups. I have mails from 2011
+    mentioning its presence in \PDFTEX\ 1.50 (which was targeted in 2008) but
+    somehow it never ended up in a production version at that time (and we're
+    still not at that version). In \CONTEXT\ we already had a command with that
+    name so there we use \tex {normalexpanded}. Users normally can just use the
+    \CONTEXT\ variant of \type {\expanded}.
+\NC \NR
+\NC \tex {unexpanded} \NC \type {{tokens}} \NC
+    The given token list is hidden from expansion. Again, in \CONTEXT\ we already
+    had a command serving as prefix for definitions so instead we use \tex
+    {normalunexpanded}. In the core of \CONTEXT\ this new \ETEX\ command is hardly
+    used.
+\NC \NR
+\NC \tex {detokenize} \NC \type {{tokens}} \NC
+    The given tokenlist becomes (basically) verbatim \TEX\ code. We had something
+    like that in \CONTEXT\ but have no nameclash. It is used in a few places. It's
+    also an \ETEX\ command.
+\NC \NR
+\NC \tex {scantokens} \NC \type {{tokens}} \NC
+    This primitive interprets its argument as a pseudo file. We don't really use it.
+\NC \NR %
+\NC \tex {scantextokens} \NC \type {{tokens}} \NC
+    This \LUATEX\ primitive does the same but has no end|-|of|-|file side
+    effects. This one is also not really used in \CONTEXT.
+\NC \NR
+\NC \tex {protected} \NC \type {\.def} \NC
+    The definition following this prefix, introduced in \ETEX, is unexpandable in
+    the context of expansion. We already used such a command in \CONTEXT\ but
+    with a completely different meaning so use \tex {normalprotected} as prefix
+    or \tex {unexpanded} which is an alias.
+\NC \NR
+\stoptabulate
+
+Here I will present two other extensions in \LUATEX\ that can come in handy, and
+they are there simply because their effect can hardly be realized otherwise
+(never say never in \TEX). One has to do with immediately applying a definition,
+the other with user defined conditions. The first one relates directly to
+expansion, the second one concerns conditions and relates more to parsing
+branches which on purpose avoids expansion.
+
+For the first one I use some silly examples. I must admit that although I can
+envision useful application, I really need to go over the large amount of
+\CONTEXT\ source code to really find a place where it is making things better.
+Take the following definitions:
+
+\startbuffer
+\newcount\NumberOfCalls
+
+\def\TestMe{\advance\NumberOfCalls1 }
+
+\edef\Tested{\TestMe foo:\the\NumberOfCalls}
+\edef\Tested{\TestMe foo:\the\NumberOfCalls}
+\edef\Tested{\TestMe foo:\the\NumberOfCalls}
+
+\meaning\Tested
+\stopbuffer
+
+\typebuffer
+
+The result is a macro \tex {Tested} that not only has the unexpanded incrementing
+code in its body but also hasn't done any advancing:
+
+\getbuffer
+
+Of course when you're typesetting something, this kind of expansion normally is
+not needed. Instead of the above definition we can define \tex {TestMe} in a way
+that expands the assignment immediately. You need of course to be aware of
+preventing look ahead interference by using a space or \tex {relax} (often an
+expression works better as it doesn't leave an \tex {relax}).
+
+\startbuffer
+\def\TestMe{\immediateassignment\advance\NumberOfCalls1 }
+
+\edef\Tested{\TestMe bar:\the\NumberOfCalls}
+\edef\Tested{\TestMe bar:\the\NumberOfCalls}
+\edef\Tested{\TestMe bar:\the\NumberOfCalls}
+
+\meaning\Tested
+\stopbuffer
+
+\typebuffer
+
+This time the counter gets updated and we don't see interference in the resulting
+\tex {Tested} macro:
+
+\getbuffer
+
+Here is a somewhat silly example of an expanded comparison of two \quote
+{strings}:
+
+\startbuffer
+\def\expandeddoifelse#1#2#3#4%
+  {\immediateassignment\edef\tempa{#1}%
+   \immediateassignment\edef\tempb{#2}%
+   \ifx\tempa\tempb
+     \immediateassignment\def\next{#3}%
+   \else
+     \immediateassignment\def\next{#4}%
+   \fi
+   \next}
+
+\edef\Tested
+  {(\expandeddoifelse{abc}{def}{yes}{nop}/%
+    \expandeddoifelse{abc}{abc}{yes}{nop})}
+
+\meaning\Tested
+\stopbuffer
+
+\typebuffer
+
+I don't remember many cases where I needed such an expanded comparison. We have a
+variant in \CONTEXT\ that uses \LUA\ but that one is not really used in the core.
+Anyway, the above code gives:
+
+\getbuffer
+
+You can do the same assignments as in preambles of \tex {halign} and after \tex
+{accent} which means that assignments to box registers are blocked (boxing
+involves grouping and delayed assignments and so). The error you will get when
+you use a non||assignment command refers to a prefix, because internally such
+commands are called prefixed commands. Leading spaces and \tex {relax} are
+ignored.
+
+In addition to this one|-|time immediate assignment a pseudo token list variant
+is provided, so the above could be rewritten to:
+
+\starttyping
+\def\expandeddoifelse#1#2#3#4%
+  {\immediateassigned {
+     \edef\tempa{#1}
+     \edef\tempb{#2}
+   }%
+   \ifx\tempa\tempb
+     \immediateassignment\def\next{#3}%
+   \else
+     \immediateassignment\def\next{#4}%
+   \fi
+   \next}
+\stoptyping
+
+While \tex {expanded} first builds a token lists that then gets used, the \tex
+{immediateassigned} primitive just walls over the list delimited by curly braces.
+
+A next extension concerns conditions. If you have done a bit of extensive \TEX\
+programming you know that nested conditions need to be properly constructed in
+for instance macro bodies. This is because (for good reason) \TEX\ goes into a
+fast scanning mode when there is a match and it has to skip the \tex {else} upto
+\tex {fi} branch. In order to do that properly a nested \tex {if} in there needs
+to have a matching \tex {fi}.
+
+In practice this is no real problem and careful coding will never give a problem
+here: you can either hide nested code in a macro or somehow jump over nested
+conditions if really needed. Actually you only need to care when you pickup a
+token inside the branch because likely you don't want to pick up for instance a
+\tex {fi} but something that comes after it. Say that we have a sane conditional
+setup like this:
+
+\starttyping
+\newif\iffoo \foofalse
+\newif\ifbar \bartrue
+
+\ifoo
+  \ifbar \else \fi
+\else
+  \ifbar \else \fi
+\fi
+\stoptyping
+
+Here the \tex {iffoo} and \tex {ifbar} need to be equivalent to \tex {iftrue} or
+\tex {iffalse} in order to succeed well and that is what for instance \tex
+{footrue} and \tex {foofalse} will do: change the meaning of \tex {iffoo}.
+
+But imagine that you want something more complex. You want for instance to let
+\tex {ifbar} do some calculations. In that case you want it to behave a bit like
+what a so called \type {vardef} in \METAPOST\ does: the end result is what
+matters. Now, because \TEX\ macros often are a complex mix of expandable and
+non|-|expandable this is not that trivial. One solution is a dedicated definer,
+say \tex {cdef} for defining a macro with conditional properties. I actually
+implemented such a definer a few years ago but left it so long in a folder with
+ideas that I only found it back after I had come up with another solution. It was
+probably proof that it was not that good an idea.
+
+The solution implemented in \LUATEX\ is just a special case of a test: \tex
+{ifcondition}. When looking at the next example, keep in mind that from the
+perspective of \TEX's scanner it only needs to know if something is a token that
+does some test and has a matching \tex {fi}. For that purpose you can consider
+\tex {ifcondition} to be \tex {iftrue}. When \TEX\ actually wants to do a test,
+which is the case in the true branch, then it will simply ignore this \tex
+{ifcondition} primitive and expands what comes after it (which is \TEX's natural
+behaviour). Effectively \tex {ifcondition} has no meaning except from when it has
+to be skipped, in which case it's a token flagged as \tex {if} kind of command.
+
+\starttyping
+\unexpanded\def\something#1#2%
+  {\edef\tempa{#1}%
+   \edef\tempb{#2}
+   \ifx\tempa\tempb}
+
+\ifcondition\something{a}{b}%
+    \ifcondition\something{a}{a}%
+        true 1
+    \else
+        false 1
+    \fi
+\else
+    \ifcondition\something{a}{a}%
+        true 2
+    \else
+        false 2
+    \fi
+\fi
+\stoptyping
+
+Wrapped in a macro you can actually make this fully expandable when you use the
+previously mentioned immediate assignment. Here is another example:
+
+\starttyping
+\unexpanded\def\onoddpage
+  {\ifodd\count0 }
+
+\ifcondition\onoddpage odd \else even \fi page
+\stoptyping
+
+The previously defined comparison macro can now be rewritten as:
+
+\starttyping
+\def\equaltokens#1#2%
+  {\immediateassignment\edef\tempa{#1}%
+   \immediateassignment\edef\tempb{#2}%
+   \ifx\tempa\tempb}
+
+\def\expandeddoifelse#1#2#3#4%
+  {\ifcondition\equaltokens{#1}{#2}%
+     \immediateassignment\def\next{#3}%
+   \else
+     \immediateassignment\def\next{#4}%
+   \fi
+   \next}
+\stoptyping
+
+When used this way it will of course also work without the \tex {ifcondition} but
+when used nested it can be like this. This last example also demonstrates that
+this feature probably only makes sense in more complicated cases where more work
+is done in the \tex {onoddpage} or \tex {equaltokens} macro. And again, I am not
+sure if for instance in \CONTEXT\ I have a real use for it because there are only
+a few cases where nesting like this could benefit. I did some tests with a low
+level macro where it made the code look nicer. It was actually a bit faster but
+most core macros are not called that often. Although the overhead of this feature
+can be neglected, performance should not be the reason for using it: in \CONTEXT\
+for instance one can often only measure such possible speed|-|ups on macros that
+are called tens or hundreds of thousands of times and that seldom happens in a
+real run end even then a change from say 0.827 seconds to 0.815 seconds for 10K
+calls of a complex case is just noise as the opposite can also happen.
+
+Although not strictly necessary these extensions might make some code look better
+so that is why they officially will be available in the 1.09 release of \LUATEX\
+in fall 2018. It might eventually inspire me to go over some code and see where I
+can improve the look and feel.
+
+The last few years I have implemented some more ideas as local experiments, for
+instance \tex {futurelet} variant or a simple (one level) \tex {expand}, but in
+the end rejected them because there is no real benefit in them (no better looking
+code, no gain in performance, hard to document, possible side effects, etc.), so
+it is very unlikely that we will have more extensions like this. After all, we
+could do more than 40 years without them. Although \unknown\ who knows what we
+will provide in \LUATEX\ version~2.

+\startchapter[title={Tricky fences}]
+
+Occasionally one of my colleagues notices some suboptimal rendering and asks me
+to have a look at it. Now, one can argue about \quotation {what is right} and
+indeed there is not always a best answer to it. Such questions can even be a
+nuisance; let's think of the following scenario. You have a project where \TEX\
+is practically the only solution. Let it be an \XML\ rendering project, which
+means that there are some boundary conditions. Speaking in 2017 we find that in
+most cases a project starts out with the assumption that everything is possible.
+
+Often such a project starts with a folio in mind and therefore by decent tagging
+to match the educational and esthetic design. When rendering is mostly automatic
+and concerns too many (variants) to check all rendering, some safeguards are used
+(an example will be given below). Then different authors, editors and designers
+come into play and their expectations, also about what is best, often conflict.
+Add to that rendering for the web, and devices and additional limitations show
+up: features get dropped and even more cases need to be compensated (the quality
+rules for paper are often much higher). But, all that defeats the earlier
+attempts to do well because suddenly it has to match the lesser format. This in
+turn makes investing in improving rendering very inefficient (read: a bottomless
+pit because it never gets paid and there is no way to gain back the investment).
+Quite often it is spacing that triggers discussions and questions what rendering
+is best. And inconsistency dominates these questions.
+
+So, in case you wonder why I bother with subtle aspects of rendering as discussed
+below, the answer is that it is not so much professional demand but users (like
+my colleagues or those on the mailing lists) that make me look into it and often
+something that looks trivial takes days to sort out (even for someone who knows
+his way around the macro language, fonts and the inner working of the engine).
+And one can be sure that more cases will pop up.
+
+All this being said, let's move on to a recent example. In \CONTEXT\ we support
+\MATHML\ although in practice we're forced to a mix of that standard and
+\ASCIIMATH. When we're lucky, we even get a mix with good old \TEX-encoded math.
+One problem with an automated flow and processing (other than raw \TEX) is that
+one can get anything and therefore we need to play safe. This means for instance
+that you can get input like this:
+
+\starttyping
+f(x) + f(1/x)
+\stoptyping
+
+or in more structured \TEX\ speak:
+
+\startbuffer
+$f(x) + f(\frac{1}{x})$
+\stopbuffer
+
+\typebuffer
+
+Using \TeX\ Gyre Pagella, this renders as: {\UseMode\zerocount\inlinebuffer}, and
+when seeing this a \TEX\ user will revert to:
+
+\startbuffer
+$f(x) + f\left(\frac{1}{x}\right)$
+\stopbuffer
+
+\typebuffer
+
+which gives: {\UseMode\zerocount \inlinebuffer}. So, in order to be robust we can
+always use the \type {\left} and \type {\right} commands, can't we?
+
+\startbuffer
+$f(x) + f\left(x\right)$
+\stopbuffer
+
+\typebuffer
+
+which gives {\UseMode\zerocount \inlinebuffer}, but let's blow up this result a
+bit showing some additional tracing from left to right, now in Latin Modern:
+
+\startbuffer[blownup]
+\startcombination[nx=3,ny=2,after=\vskip3mm]
+    {\scale[scale=4000]{\hbox{$f(x)$}}}
+        {just characters}
+    {\scale[scale=4000]{\ruledhbox{\showglyphs \showfontkerns \showfontitalics$f(x)$}}}
+        {just characters}
+    {\scale[scale=4000]{\ruledhbox{\showglyphs \showfontkerns \showfontitalics \showmakeup$f(x)$}}}
+        {just characters}
+    {\scale[scale=4000]{\hbox{$f\left(x\right)$}}}
+        {using delimiters}
+    {\scale[scale=4000]{\ruledhbox{\showglyphs \showfontkerns \showfontitalics$f\left(x\right)$}}}
+        {using delimiters}
+    {\scale[scale=4000]{\ruledhbox{\showglyphs \showfontkerns \showfontitalics \showmakeup$f\left(x\right)$}}}
+        {using delimiters}
+\stopcombination
+\stopbuffer
+
+\startlinecorrection
+\UseMode\zerocount
+\switchtobodyfont[modern]\getbuffer[blownup]
+\stoplinecorrection
+
+When we visualize the glyphs and kerns we see that there's a space instead of a
+kern when we use delimiters. This is because the delimited sequence is processed
+as a subformula and injected as a so|-|called inner object and as such gets
+spaced according to the ordinal (for the $f$) and inner (\quotation {fenced} with
+delimiters $x$) spacing rules. Such a difference normally will go unnoticed but
+as we mentioned authors, editors and designers being involved, there's a good
+chance that at some point one will magnify a \PDF\ preview and suddenly notice
+that the difference between the $f$ and $($ is a bit on the large side for simple
+unstacked cases, something that in print is likely to go unnoticed. So, even when
+we don't know how to solve this, we do need to have an answer ready.
+
+When I was confronted by this example of rendering I started wondering if there
+was a way out. It makes no sense to hard code a negative space before a fenced
+subformula because sometimes you don't want that, especially not when there's
+nothing before it. So, after some messing around I decided to have a look at the
+engine instead. I wondered if we could just give the non|-|scaled fence case the
+same treatment as the character sequence.
+
+Unfortunately here we run into the somewhat complex way the rendering takes
+place. Keep in mind that it is quite natural from the perspective of \TEX\
+because normally a user will explicitly use \type {\left} and \type {\right} as
+needed, while in our case the fact that we automate and therefore want a generic
+solution interferes (as usual in such cases).
+
+Once read in the sequence \type {f(x)} can be represented as a list:
+
+\starttyping
+list = {
+ {
+  id = "noad", subtype = "ord", nucleus = {
+   {
+    id = "mathchar", fam = 0, char = "U+00066",
+   },
+  },
+ },
+ {
+  id = "noad", subtype = "open", nucleus = {
+   {
+    id = "mathchar", fam = 0, char = "U+00028",
+   },
+  },
+ },
+ {
+  id = "noad", subtype = "ord", nucleus = {
+   {
+    id = "mathchar", fam = 0, char = "U+00078",
+   },
+  },
+ },
+ {
+  id = "noad", subtype = "close", nucleus = {
+   {
+    id = "mathchar", fam = 0, char = "U+00029",
+   },
+  },
+ },
+}
+\stoptyping
+
+The sequence \type {f \left( x \right)} is also a list but now it is a tree (we
+leave out some unset keys):
+
+\starttyping
+list = {
+ {
+  id = "noad", subtype = "ord", nucleus = {
+   {
+    id = "mathchar", fam = 0, char = "U+00066",
+   },
+  },
+ },
+ {
+  id = "noad", subtype = "inner", nucleus = {
+   {
+    id = "submlist", head = {
+     {
+      id = "fence", subtype = "left", delim = {
+       {
+        id = "delim", small_fam = 0, small_char = "U+00028",
+       },
+      },
+     },
+     {
+      id = "noad", subtype = "ord", nucleus = {
+       {
+        id = "mathchar", fam = 0, char = "U+00078",
+       },
+      },
+     },
+     {
+      id = "fence", subtype = "right", delim = {
+       {
+        id = "delim", small_fam = 0, small_char = "U+00029",
+       },
+      },
+     },
+    },
+   },
+  },
+ },
+}
+\stoptyping
+
+So, the formula \type {f(x)} is just four characters and stays that way, but with
+some inter|-|character spacing applied according to the rules of \TEX\ math. The
+sequence \typ {f \left( x \right)} however becomes two components: the \type {f}
+is an ordinal noad,\footnote {Noads are the mathematical building blocks.
+Eventually they become nodes, the building blocks of paragraphs and boxed
+material.} and \typ {\left( x \right)} becomes an inner noad with a list as a
+nucleus, which gets processed independently. The way the code is written this is
+what (roughly) happens:
+
+\startitemize
+\startitem
+    A formula starts; normally this is triggered by one or two dollar signs.
+\stopitem
+\startitem
+    The \type {f} becomes an ordinal noad and \TEX\ goes~on.
+\stopitem
+\startitem
+    A fence is seen with a left delimiter and an inner noad is injected.
+\stopitem
+\startitem
+    That noad has a sub|-|math list that takes the left delimiter up to a
+    matching right one.
+\stopitem
+\startitem
+    When all is scanned a routine is called that turns a list of math noads into
+    a list of nodes.
+\stopitem
+\startitem
+    So, we start at the beginning, the ordinal \type {f}.
+\stopitem
+\startitem
+    Before moving on a check happens if this character needs to be kerned with
+    another (but here we have an ordinal|-|inner combination).
+\stopitem
+\startitem
+    Then we encounter the subformula (including fences) which triggers a nested
+    call to the math typesetter.
+\stopitem
+\startitem
+    The result eventually gets packaged into a hlist and we're back one level up
+    (here after the ordinal \type {f}).
+\stopitem
+\startitem
+    Processing a list happens in two passes and, to cut it short, it's the second
+    pass that deals with choosing fences and spacing.
+\stopitem
+\startitem
+    Each time when a (sub)list is processed a second pass over that list
+    happens.
+\stopitem
+\startitem
+    So, now \TEX\ will inject the right spaces between pairs of noads.
+\stopitem
+\startitem
+    In our case that is between an ordinal and an inner noad, which is quite
+    different from a sequence of ordinals.
+\stopitem
+\stopitemize
+
+It's these fences that demand a two-pass approach because we need to know the
+height and depth of the subformula. Anyway, do you see the complication? In our
+inner formula the fences are not scaled, but this is not communicated back in the
+sense that the inner noad can become an ordinal one, as in the simple \type {f(}
+pair. The information is not only lost, it is not even considered useful and the
+only way to somehow bubble it up in the processing so that it can be used in the
+spacing requires an extension. And even then we have a problem: the kerning that
+we see between \type {f(} is also lost. It must be noted that this kerning is
+optional and triggered by setting \type {\mathitalicsmode=1}. One reason for this
+is that fonts approach italic correction differently, and cheat with the
+combination of natural width and italic correction.
+
+Now, because such a workaround is definitely conflicting with the inner workings
+of \TEX, our experimenting demands another variable be created: \type
+{\mathdelimitersmode}. It might be a prelude to more manipulations but for now we
+stick to this one case. How messy it really is can be demonstrated when we render
+our example with Cambria.
+
+\startlinecorrection
+\UseMode\zerocount
+\switchtobodyfont[cambria]\getbuffer[blownup]
+\stoplinecorrection
+
+If you look closely you will notice that the parenthesis are moved up a bit. Also
+notice the more accurate bounding boxes. Just to be sure we also show Pagella:
+
+\startlinecorrection
+\UseMode\zerocount
+\switchtobodyfont[pagella]\getbuffer[blownup]
+\stoplinecorrection
+
+When we really want the unscaled variant to be somewhat compatible with the
+fenced one we now need to take into account:
+
+\startitemize[packed]
+\startitem
+    the optional axis|-|and|-|height|/|depth related shift of the fence (bit 1)
+\stopitem
+\startitem
+    the optional kern between characters (bit 2)
+\stopitem
+\startitem
+    the optional space between math objects (bit 4)
+\stopitem
+\stopitemize
+
+Each option can be set (which is handy for testing) but here we will set them
+all, so, when \type {\mathdelimitersmode=7}, we want cambria to come out as
+follows:
+
+\startlinecorrection
+\UseMode\plusseven
+\switchtobodyfont[cambria]\getbuffer[blownup]
+\stoplinecorrection
+
+When this mode is set the following happens:
+
+\startitemize
+\startitem
+    We keep track of the scaling and when we use the normal size this is
+    registered in the noad (we had space in the data structure for that).
+\stopitem
+\startitem
+    This information is picked up by the caller of the routine that does the
+    subformula and stored in the (parent) inner noad (again, we had space for
+    that).
+\stopitem
+\startitem
+    Kerns between a character (ordinal) and subformula (inner) are kept,
+    which can be bad for other cases but probably less than what we try
+    to solve here.
+\stopitem
+\startitem
+    When the fences are unscaled the inner property temporarily becomes
+    an ordinal one when we apply the inter|-|noad spacing.
+\stopitem
+\stopitemize
+
+Hopefully this is good enough but anything more fancy would demand drastic
+changes in one of the most sensitive mechanisms of \TEX. It might not always work
+out right, so for now I consider it an experiment, which means that it can be
+kept around, rejected or improved.
+
+In case one wonders if such an extension is truly needed, one should also take
+into account that automated typesetting (also of math) is probably one of the
+areas where \TEX\ can shine for a while. And while we can deal with much by using
+\LUA, this is one of the cases where the interwoven and integrated parsing,
+converting and rendering of the math machinery makes it hard. It also fits into a
+further opening up of the inner working by modes.

+
+Another objection to such a solution can be that we should not alter the engine
+too much. However, fences already are an exception and treated specially (tests
+and jumps in the program) so adding this fits reasonably well into that part of
+the design.
+
+In the following examples we demonstrate the results for Latin Modern, Cambria
+and Pagella when \type {\mathdelimitersmode} is set to zero or one. First we show
+the case where \type {\mathitalicsmode} is disabled:

+So is this all worth the effort? I don't know, but at least I got the picture and

+\startchapter[title={The state of \PDF}]
+
+\startsection[title={Introduction}]
+
+Below I will spend some words on the state of \PDF\ in \CONTEXT\ mid 2018. These
+are just some reflections, not an in|-|depth discussion of the state of affairs. I
+sometimes feel the need to wrap up.
+
+\stopsection
+
+\startsection[title={Media}]
+
+For over two decades \CONTEXT\ has supported fancy \PDF\ features like movies and
+sound. In fact, as happens more, the flexibility of \TEX\ made it possible to
+support such features right after they became available, often even before other
+applications supported them.
+
+The first approach to support such media clips was relatively easy. In \PDF\ one
+has the text flow, resulting from the typesetting process, either or not enhanced
+with images that are referred to from the flow. In that respect images are an
+integral part of \PDF. On a separate layer there can be annotations. There are
+many kinds and they are originally a sort of extension mechanism that permits
+plugins to add features to a document. Examples of this are hyperlinks and the
+already mentioned media clips. Video was supported by the quicktime movie plugin.
+As far as I know in the meantime that plugin has been dropped as official part of
+Acrobat but one can still plug it in.
+
+Later an extra mechanism was introduced, tagged renditions. It separates the
+views from the media and was more complex. When I first played with it, quite
+some media were possible, and I made a demo that could handle mov, mp3, smi and
+swf files. But last time I checked none of these really worked, apart from the
+swf file. One gets pop|-|ups for missing viewers and a look at the reader
+preferences makes one pessimistic about future support anyway. But one should be
+able to set up a list of useable players with this mechanism (although only an
+Adobe one seems to be okay so we're back to where we started).
+
+At some point support for u3d was added. Interesting is that there is quite some
+infrastructure described in the \PDF\ standard. Also something called rich media
+was introduced and that should replace the former video and audio annotations
+(definitely in \PDF\ version 2) and probably some day the renditions will no
+longer be supported either. Open source \PDF\ viewers just stuck to supporting
+text and static images.
+
+Now, do these rich media work well? Hardly. The standard leaves it to the viewer
+and provides ways to define viewers (although it's unclear to me how that works
+out in practice.) Basically in \PDF\ version 2 there is no native support for
+simple straightforward video. One has to construct a complex set of related
+annotations.
+
+One can give arguments (like security risks) for not supporting all these fancy
+features but then why make rich media part of the specification at all? Browsers
+beat \PDF\ viewers in showing media and as browsers can operate in kiosk mode I
+suppose that it's not that hard to delegate showing whatever you want in an
+embedded window in the \PDF\ viewer. Or why not simply support videolan out of
+the box. All we need is the ability to view movies and control them (play, pause,
+stop, rewind, etc). Where \HTML\ evolved towards easier media support, \PDF\
+evolved to more obscurity.
+
+So, how bad is it really? There are \PDF\ files around that have video! Indeed,
+but the way they're supposed to do this is as follows: currently one actually has
+to embed a shockwave video player (a user interface around something built|-|in)
+and let that player show for instance an mp4 movie. However, support for
+shockwave (flash) will be dropped in 2020 and that renders documents that use it
+obsolete. This even makes one wonder about \JAVASCRIPT\ and widgets like form
+fields, also a rather moving and somewhat unstable target. (I must have a
+document being a calculator somewhere made in the previous century, in the early
+days of \PDF.)
+
+I think that the plugin model failed already rather early in the \PDF\ history if
+only because it made no sense to develop them when in a next version of Acrobat
+the functionality was copied in the core. In a similar fashion \JAVASCRIPT\
+support seems to have stalled.
+
+Unfortunately the open source viewers never catched on with media, forms and
+\JAVASCRIPT\ and therefore there has been no momentum created to keep things
+supported. It all makes efforts spent on supporting this kind of \PDF\ features a
+waste of time. It also makes one careful in using them: it only works on the
+short term.
+
+Get me right, I'm not talking of complex media like 3d or animations but of
+straightforward video support. I understand that the rich media framework tries
+to cover complex cases but it's simple cases that carry the format. On the other
+hand, one can wonder why the \PDF\ format makes it possible to specify behaviour
+that in practice depends on \JAVASCRIPT\ and therefore could as well have been
+delegated to \JAVASCRIPT\ as well. It would probably have been much cleaner.
+\footnote {It looks like mu\PDF\ in 2018 got some support related to widgets aka
+fields but alas not for layers which would be quite useful.}
+
+The \PDF\ version 2 specification mentions \type {3D}, \type {Video} and \type
+{Audio} as primary content types so maybe future viewers will support video out
+of the box. Who knows. We try to keep up in \CONTEXT\ because it's often not that
+complex to support \PDF\ features but with hardly any possibility to test them,
+they have a low priority. And with Acrobat moving to the cloud and thereby
+creating a more of less lifelong dependency on remote resources it doesn't become
+much interesting to explore those routes either.
+
+\stopsection
+
+\startsection[title={Accessibility}]
+
+A popular \PDF\ related topic is accessibility. One aspect of that is tagged
+\PDF. This substandard is in my opinion not something that deserves a price for
+beauty. I know that there are \CONTEXT\ users who need to be compliant but I
+always wonder what a publisher really does with such a file. It's a bit like
+requiring \XML\ as source but at the same time sacrificing really rich encoded
+and sources for tweaks that suite the current limitations of for instance browsers,
+tool|-|chains and competence. We've seen it happen.
+
+Support for tagged \PDF\ has been available in \CONTEXT\ already for a while but
+as far as I know only Acrobat professional can do something with it. The reason
+for tagging is that a document is then useable for (for instance) visually
+impaired users, but aren't they better served with a proper complete and very
+structured source in some format that tools suitable for it can use? How many
+publishers distribute \PDF\ files while they can still make money on prints? How
+many are really interested in distributing enriched content that then can be
+reused somehow? And how many are willing to invest in tools instead of waiting
+for it to happen for free? It's a bit cheap trick to just expect authors (and
+their in the case of \TEX\ free tools) to suit a publishers needs. Anyway, just
+as with advanced interactive documents or forms, I wonder if it will catch on. At
+least no publisher ever asked us and by the time they might do the competition of
+web based dissemination could have driven \PDF\ to the background. But, in
+\CONTEXT\ we will keep supporting such features anyway, if only because it's
+quite doable. But \unknown\ it's user demand that drives development, not the
+market, which means that the motivation for implementing such features depends on
+user input as well as challenging aspects that make it somewhat fun to spend time
+on them.
+
+\stopsection
+
+\startsection[title={Quality assurance}]
+
+Another aspect popping up occasionally is validation. I'm not entirely sure what
+drives that but delegating a problem can be one reason. Often we see publishers
+and printers use old versions of \PDF\ related tools. Also, some workflows are
+kind of ancient anyway and are more driven by \POSTSCRIPT\ history than \PDF\
+possibilities. I sometimes get the impression that it takes at least a decade for
+these things to catch on, and by that time it doesn't matter any more that \TEX\
+and friends were at the front: their users are harassed by what the market
+demands by then.
+
+Support for several standards related to validation is already part of \CONTEXT\
+for quite a while. For instance the bump from \PDF\ 1.7 to 2.0 was hardly worth
+noticing, simply because there are not that many fundamental changes. Adapting
+\LUATEX\ was trivial (and actually not really needed), and macro packages can
+provide what is needed without much problems. So, yes, we can support it without
+much hassle. Personally I never ran into a case where validation was really
+needed. The danger of validation is that it can give a false impression of
+quality. And as with everything quality control created a market. As with other
+features it is users who drive the availability of support for this. After all,
+they are the ones testing it and figuring out the often fuzzy specifications.
+These are things that one can always look at in retrospect (like: it has to be
+done this or that way) while in practice in order to be an early adopter one has
+to gamble a bit and see where it fails or succeeds. Fortunately it's relatively
+easy to adapt macro packages and \CONTEXT\ users are willing to update so it's
+not really an issue.
+
+Putting a stamp of approval on a \PDF\ cannot hide the inconsistencies between
+for instance vector graphics produced by a third party. They also don't expose
+inconsistent use of color and fonts. The page streams produced by \LUATEX\ are
+simple and clean enough to not give problems with validation. The problem lays
+more with resources coming from elsewhere. When you're phoned by a printing house
+about an issue with \RGB\ images in a file where there is no sign of \RGB\ being
+used but where a validator reports an issue, you're lucky when an experienced
+printer dating back decades then replies that he already had that impression and
+will contact the origin. There is no easy way out of this but educating users
+(authors) is an option. However, they are often dependent on the publishers and
+departments that deal with these and those tend to come with directives that the
+authors cannot really argue with (or about).
+
+\stopsection
+
+\startsection[title={Interactivity}]
+
+This is an area where \TEX\ (an therefore also \CONTEXT) always had an edge,
+There is a lot possible and in principle all that \PDF\ provides can be
+supported. But the more fancy one goes, the more one depends on Acrobat.
+Interactivity in \PDF\ evolved stepwise and is mostly market driven. As a result
+it is (or was) not always consistent. This is partly due to the fact that we have
+a chicken|-|egg issue: you need typesetting machinery, viewer as well as a
+standard.
+
+The regular hyperlinks, page or named driven are normally supported by viewers.
+Some redefined named destinations (like going to a next page, or going back in a
+chain of followed links) not always. Launching applications, as it also relates
+to security, can be qualified as an unreliable mechanism. More advanced linking,
+for instance using \JAVASCRIPT\ is hardly supported. In that respect \PDF\
+viewers lag way behind \HTML\ browsers. I understand that there can be security
+risks involved. It's interesting to see that in Acrobat one can mess with
+internals of files which makes the \API\ large and complex, but if we stick to
+the useful core, the amount of interfacing needed is quite small. Lack of support
+in open source viewers (we're talking of about two decades now) made me loose
+interest in these features but they are and will be supported in \CONTEXT. We'll
+see if and when viewers catch up.
+
+Comments and attachments are also part of interactivity and of course we
+supported them right from the start. Some free viewers also support them by now.
+Personally I never use comments but they can be handy for popping up information
+or embedding snippets or (structured) sources (like \MATHML\ or bibliographic
+data). In \CONTEXT\ we can even support \PDF\ inclusion with (a reasonable)
+subset of these so called annotations. As the \PDF\ standard no longer evolves
+much we can expect all these features to become stable.
+
+\stopsection
+
+\startsection[title={Summary}]
+
+We have always supported the fancy \PDF\ features and we will continue doing so
+in \CONTEXT . However, many of them depends on what viewers support, and after
+decades of \PDF\ that is still kind of disappointing, which is not that
+motivating. We'll see what happens.

+\startchapter[title={Modern Latin}]
+
+\startsection[title={Introduction}]
+
+In \CONTEXT, already in \MKII, we have a feature tagged \quote {effects} that can
+be used to render a font in outline or bolder versions. It uses some low level
+\PDF\ directives to accomplish this and it works quite well. When a user on the
+\CONTEXT\ list asked if we could also provide it as a font feature in the
+repertoire of additional features in \CONTEXT, I was a bit reluctant to provide
+that because it operates at another level than the glyph stream. Also, such a
+feature can be abused and result in a bad looking document. However, by adding a
+few simple options to the \LUATEX\ engine such a feature could actually be
+achieved rather easy: it was trivial to implement given that we can influence
+font handling at the \LUA\ end. In retrospect extended and pseudo slanted fonts
+could be done this way too but there we have some historic ballast. Also, the
+backend now handles such transformations very efficient because they are combined
+with font scaling. Anyway, by adding this feature in spite of possible
+objections, I could do some more advanced experiments.
+
+In the following pages I will demonstrate how we support effects as a feature in
+\CONTEXT. Instead of simply applying some magic \PDF\ text operators in the
+backend a more integrated approach is used. The difference with the normal effect
+mechanism is that where the one described here is bound to a font instance while
+the normal mechanism operates on the glyph stream.
+
+\stopsection
+
+\startsection[title={The basics}]
+
+\definefontsynonym[DemoSerif][file:lmroman10-regular]
+
+Let's start with a basic boldening example. First we demonstrate a regular Latin
+Modern sample (using \type {ward.tex}):
+
+\startnarrower
+    \definedfont[DemoSerif*default]
+    \samplefile{ward}
+\stopnarrower
+
+This font looks rather thin (light). Next we define an effect or \type {0.2} and
+typeset the same sample:
+
+\startbuffer
+\definefontfeature
+  [effect-1]
+  [effect=.2]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startnarrower
+    \definedfont[DemoSerif*default,effect-1]
+    \samplefile{ward}
+\stopnarrower
+
+This simple call gives reasonable default results. But you can have more control
+than this. The previous examples use the following properties:
+
+{\definedfont[DemoSerif*default,effect-1] \showfonteffect}
+
+\startbuffer
+\definefontfeature
+  [effect-2]
+  [effect={width=.3}]
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startnarrower

+\stopnarrower

+In order to support this I had to make some choices. The calculations involved
+are best explained in terms of \CONTEXT\ font machinery.
+
+\startformula
+    \Delta _{\text{wd}}  = \text{effect}   _{\text{wdelta}}
+                    \times \text{parameter}_{\text{hfactor}}
+                    \times \text{effect}   _{\text{width}}

+\stopformula

+                    \times \text{effect}   _{\text{width}}
+                    \times 100
+\stopformula
+
+\startformula
+    \Delta _{\text{dp}}  = \text{effect}   _{\text{ddelta}}
+                    \times \text{parameter}_{\text{vfactor}}
+                    \times \text{effect}   _{\text{width}}
+                    \times 100
+\stopformula
+
+The factors in the parameter namespace are adapted according to:
+
+\startformula
+    \Delta _{\text{factor}} = \text{effect}    _{\text{factor}}
+                       \times \text{parameters}_{\text{factor}}
+\stopformula
+
+\startformula
+    \Delta _{\text{hfactor}} = \text{effect}    _{\text{hfactor}}
+                        \times \text{parameters}_{\text{hfactor}}
+\stopformula
+
+\startformula
+    \Delta _{\text{vfactor}} = \text{effect}    _{\text{vfactor}}
+                        \times \text{parameters}_{\text{vfactor}}
+\stopformula
+
+The horizontal and vertical scaling factors default to the normal factor that
+defaults to zero so by default we have no additional scaling of for instance
+kerns. The width (wd), height (ht) and depth (dp) of a glyph are adapted in
+relation to the line width. A glyph is shifted in its bounding box by half the
+width correction. The delta defaults to one.
+
+\stopsection
+
+\startsection[title=About features]
+
+This kind of boldening has limitations especially because some fonts use
+positioning features that closely relate to the visual font properties. Let's
+give some examples. The most common positioning is kerning. Take for instance
+these shapes:
+
+\startlinecorrection
+\startMPcode
+    def SampleShapes(expr dx, offset, pw, k) =
+        picture p ; p := image (
+            draw               fullcircle scaled 1cm ;
+            draw               fullsquare scaled 1cm  shifted (dx+k,0) ;
+            draw point 8   of (fullcircle scaled 1cm)                  withcolor white ;
+            draw point 3.5 of (fullsquare scaled 1cm) shifted (dx+k,0) withcolor white ;
+        ) shifted (offset,0) ;
+        draw p withpen pencircle scaled pw ;
+        draw boundingbox p withcolor white ;
+    enddef ;
+    SampleShapes(15mm,  0mm,1mm,0mm) ;
+    SampleShapes(15mm, 40mm,2mm,0mm) ;
+    SampleShapes(17mm, 80mm,2mm,0mm) ;
+\stopMPcode
+\stoplinecorrection
+
+The first one is that we start with. The circle and square have a line width of
+one unit and a distance (kern) of five units. The second pair has a line width of
+two units and the same distance while the third pair has a distance of seven
+units. So, in the last case we have just increased the kern with a value relative
+to the increase of line width.
+
+\startlinecorrection
+\startMPcode
+    SampleShapes(15mm,  0mm,1mm,0mm) ;
+    SampleShapes(15mm, 40mm,2mm,2mm) ;
+    SampleShapes(17mm, 80mm,2mm,2mm) ;
+\stopMPcode
+\stoplinecorrection
+
+In this example we have done the same but we started with a distance of zero. You
+can consider this a kind of anchoring. This happens in for instance cursive
+scripts where entry and exit points are used to connect shapes. In a latin script
+you can think of a poor|-|mans attachment of a cedilla or ogonek. But what to do
+with for instance an accent on top of a character? In that case we could do the
+same as with kerning. However, when we mix styles we would like to have a
+consistent height so maybe there scaling is not a good idea. This is why we can
+set the factors and deltas explictly for vertical and horizontal movements.
+However, this will only work well when a font is consistent in how it applies
+these movements. In this case, if could recognize cursive anchoring (the last
+pair in the example) we could compensate for it.
+
+\startMPinclusions
+    def SampleShapes(expr dx, offset, pw, k) =
+        picture p ; p := image (
+            draw               fullcircle scaled 1cm ;
+            draw               fullsquare scaled 1cm  shifted (dx+k,0) ;
+            draw point 8   of (fullcircle scaled 1cm)                  withcolor white ;
+            draw point 3.5 of (fullsquare scaled 1cm) shifted (dx+k,0) withcolor white ;
+        ) shifted (offset,0) ;
+        draw p withpen pencircle scaled pw ;
+        draw boundingbox p withcolor white ;
+    enddef ;
+\stopMPinclusions
+
+\startlinecorrection
+\startMPcode
+    SampleShapes(10mm,  0mm,1mm,0mm) ;
+    SampleShapes(10mm, 40mm,1mm,1mm) ;
+    SampleShapes(10mm, 80mm,2mm,0mm) ;
+    SampleShapes(10mm,120mm,2mm,2mm) ;
+\stopMPcode
+\stoplinecorrection
+
+So, an interesting extension to the positioning part of the font handler could be
+to influence all the scaling factors: anchors, cursives, single and pair wise
+positioning in both directions (so eight independent factors). Technically this
+is no big deal so I might give it a go when I have a need for it.
+
+\stopsection
+
+\startsection[title=Some (extreme) examples]
+
+The last decade buying a font has become a bit of a nightmare simply because you
+have to choose the weights that you need. It's the business model to not stick to
+four shapes in a few weights but offer a whole range and each of course costs
+money.
+
+Latin Modern is based on Computer Modern and is meant for high resolution rendering.
+The design of the font is such that you can create instances but in practice that
+isn't done. One property that let the font stand out is its bold which runs rather
+wide. However, how about cooking up a variant? For this we will use a series of
+definitions:
+

+\definefontfeature[effect-8-6-4]

+The quality of the result depends on how the font is made. For instance,
+ligatures can be whole shapes, replaced glyphs and|/|or repositioned
+glyphs, or whatever the designer thinks reasonable. In \in {figure}
+[fig:ligature-effects-mess] this is demonstrated. We use the following
+feature sets:

+We can combine the extend and effect features to get a bold running as wide as a
+normal bold. We limit the height and depth so that we can use regular and bold in
+the same sentence. It's all a matter of taste, but some control is there.

+in the vertical direction but moves along with the width.

+
+\typebuffer \start \definefontsynonym[arabictest][husayni]  \getbuffer\stop
+
+Actually, quite okay are the following. We don't over do bold here and to get
+a distinction we make the original thinner.

+\stopMPinclusions
+
+In arabic (and sometimes latin) fonts the marks (or accents in latin) are
+attached to base shapes and normally one will use the \type {mark} to anchor a
+mark to a base character or specific component of a ligature. The \type {mkmk}
+feature is then used to anchor marks to other marks. Consider the following
+example.
+
+\startlinecorrection
+\scale
+  [width=\textwidth]
+  {\startMPcode DrawShapes(1) ; \stopMPcode}
+\stoplinecorrection
+
+We start with \type {original}: a base shape with three marks: the red circle and
+blue square anchor to the base and the green triangle anchors to the blue square.
+When we bolden, the shapes will start touching. In the case of latin scripts,
+it's normal to keep the accents on the same height so this is why the third
+picture only shifts in the horizontal direction. The fourth picture demonstrates
+that we need to compensate the two bound marks. One can decide to move the lot up
+as in the fifth picture but that is no option here.
+
+Matters can be even more complex when a non circular pen is introduced. In that
+case a transformation from one font to another using the transformed \OPENTYPE\
+positioning logic (values) is even more tricky and unless one knows the
+properties (and usage) of a mark it makes no sense at all. Actually the sixths
+variant is probably nicer here but there we actually move the marks down!
+

+
+For effects this means that when it gets applied to such a font, only small
+values work out well.

+\stopsection
+
+\startsection[title=Math]
+
+Math is dubious as there is all kind of positioning involved. Future versions
+might deal with this, although bolder math (math itself has bold, so actually
+we're talking of bold with some heavy) is needed for titling. If we keep that
+in mind we can actually just bolden math and probably most will come out
+reasonable well. One of the potential troublemakers is the radical (root) sign
+that can be bound to a rule. Bumping the rules is no big deal and patching the
+relevant radical properties neither, so indeed we can do:
+

+I must admit that I cheat a bit. In order to get a better looking pseudo math
+we need to extend the shapes horizontally as well as squeeze them a bit vertically.
+So, the real effect definitions more look like this:

+\definefontfeature

+simplified to:

+\starttyping

+We leave it to your imagination to figure out what happens behind the screens.

+For sure this mechanism will create more fonts than normal but fortunately it
+can use the low level optimizations for sharing instances so in the end the
+overhead is not that large. This chapter uses 36 different fonts, creates 270
+font instances (different scaling and properties) of which 220 are shared in the

+\startsection[title=Conclusion]
+
+So what can we conclude? When we started with \LUATEX, right from the start
+\CONTEXT\ supported true \UNICODE\ math by using virtual \UNICODE\ math fonts.
+One of the objectives of the \TEX Gyre project is to come up with a robust
+complete set of math fonts, text fonts with a bunch of useful symbols, and
+finally a subset bold math font for titling. Now we have real \OPENTYPE\ math
+fonts, although they are still somewhat experimental. Because we're impatient, we
+now provide bold math by using effects but the future will learn to what extent
+the real bold math fonts will differ and be more pleasant to look at. After all,
+what we describe he is just an experiment that got a bit out of hands.
+
+% And if you wonder if this kind of messing with fonts is okay? Well, you don't
+% know what specs we sometimes get (and then ignore).

+but more a sort of wrap|-|up for myself. It anyhow show the thinking behind
+this mechanism. I'll also introduce a new \LUATEX\ feature here: subruns.
+
+\stopsection
+
+\startsection[title={The problem}]
+
+\METAPOST\ is meant for drawing graphics and adding text to them is not really
+part of the concept. Its a bit like how \TEX\ sees images: the dimensions matter,
+the content doesn't. This means that in \METAPOST\ a blob of text is an
+abstraction. The native way to create a typeset text picture is:
+
+\starttyping
+picture p ; p := btex some text etex ;
+\stoptyping
+
+In traditional \METAPOST\ this will create a temporary \TEX\ file with the words
+\type {some text} wrapped in a box that when typeset is just shipped out. The
+result is a \DVI\ file that with an auxiliary program will be transformed into a
+\METAPOST\ picture. That picture itself is made from multiple pictures, because
+each sequences of characters becomes a picture and kerns become shifts.
+
+There is also a primitive \type {infont} that takes a text and just converts it
+into a low level text object but no typesetting is done there: so no ligatures
+and no kerns are found there. In \CONTEXT\ this operator is redefined to do the
+right thing.
+
+In both cases, what ends up in the \POSTSCRIPT\ file is references to fonts and
+characters and the original idea is that \DVIPS\ understands what
+fonts to embed. Details are communicated via specials (comments) that \DVIPS\ is
+supposed to intercept and understand. This all happens in an 8~bit (font) universe.
+
+When we moved on to \PDF, a converter from \METAPOST's rather predictable and
+simple \POSTSCRIPT\ code to \PDF\ was written in \TEX. The graphic operators
+became \PDF\ operators and the text was retypeset using the font information and
+snippets of strings and injected at the right spot. The only complication was
+that a non circular pen actually produced two path of which one has to be
+transformed.
+
+At that moment it already had become clear that a more tight integration in
+\CONTEXT\ would happen and not only would that demand a more sophisticated
+handling of text, but it would also require more features not present in
+\METAPOST, like dealing with \CMYK\ colors, special color spaces, transparency,
+images, shading, and more. All this was implemented. In the next sections we will
+only discuss texts.
+
+\stopsection
+
+\startsection[title={Using the traditional method}]
+
+The \type {btex} approach was not that flexible because what happens is that
+\type {btex} triggers the parser to just grabbing everything upto the \type
+{etex} and pass that to an external program. It's special scanner mode and
+because because of that using macros for typesetting texts is a pain. So, instead
+of using this method in \CONTEXT\ we used \type {textext}. Before a run the
+\METAPOST\ file was scanned and for each \type {textext} the argument was copied
+to a file. The \type {btex} calls were scanned to and replaced by \type {textext}
+calls.
+
+For each processed snippet the dimensions were stored in order to be loaded at
+the start of the \METAPOST\ run. In fact, each text was just a rectangle with
+certain dimensions. The \PDF\ converter would use the real snippet (by
+typesetting it).
+
+Of course there had to be some housekeeping in order to make sure that the right
+snippets were used, because the order of definition (as picture) can be different
+from them being used. This mechanism evolved into reasonable robust text handling
+but of course was limited by the fact that the file was scanned for snippets. So,
+the string had to be string and not assembled one. This disadvantage was
+compensated by the fact that we could communicate relevant bits of the
+environment and apply all the usual context trickery in texts in a way that was
+consistent with the rest of the document.
+
+A later implementation could communicate the text via specials which is more
+flexible. Although we talk of this method in the past sense it is still used in
+\MKII.
+
+\stopsection
+
+\startsection[title={Using the library}]
+
+When the \MPLIB\ library showed up in \LUATEX, the same approach was used but
+soon we moved on to a different approach. We already used specials to communicate
+extensions to the backend, using special colors and fake objects as signals. But
+at that time paths got pre- and postscripts fields and those could be used to
+really carry information with objects because unlike specials, they were bound to
+that object. So, all extensions using specials as well as texts were rewritten to
+use these scripts.
+
+The \type {textext} macro changed its behaviour a bit too. Remember that a
+text effectively was just a rectangle with some transformation applied. However
+this time the postscript field carried the text and the prescript field some
+specifics, like the fact that that we are dealing with text. Using the script made
+it possible to carry some more inforation around, like special color demands.
+
+\starttyping
+draw textext("foo") ;
+\stoptyping
+
+Among the prescripts are \typ {tx_index=trial} and \typ {tx_state=trial}
+(multiple prescripts are prepended) and the postscript is \type {foo}. In a
+second run the prescript is \type {tx_index=trial} and \typ {tx_state=final}.
+After the first run we analyze all objects, collect the texts (those with a \type
+{tx_} variables set) and typeset them. As part of the second run we pass the
+dimensions of each indexed text snippet. Internally before the first run we
+\quote {reset} states, then after the first run we \quote {analyze}, and after
+the second run we \quote {process} as part of the conversion of output to \PDF.
+
+\stopsection
+
+\startsection[title={Using \type {runscript}}]
+
+When the \type {runscript} feature was introduced in the library we no longer
+needed to pass the dimensions via subscripted variables. Instead we could just
+run a \LUA\ snippets and ask for the dimensions of a text with some index. This
+is conceptually not much different but it saves us creating \METAPOST\ code that
+stored the dimensions, at the cost of potentially a bit more runtime due to the
+\type {runscript} calls. But the code definitely looks a bit cleaner this way. Of
+course we had to keep the dimensions at the \LUA\ end but we already did that
+because we stored the preprocessed snippets for final usage.
+
+\stopsection
+
+\startsection[title={Using a sub \TEX\ run}]
+
+We now come the current (post \LUATEX\ 1.08) solution. For reasons I will
+mention later a two pass approach is not optimal, but we can live with that,
+especially because \CONTEXT\ with \METAFUN\ (which is what we're talking about
+here) is quit efficient. More important is that it's kind of ugly to do all the
+not that special work twice. In addition to text we also have outlines, graphics
+and more mechanisms that needed two passes and all these became one pass
+features.
+
+A \TEX\ run is special in many ways. At some point after starting up \TEX\
+enters the main loop and begins reading text and expanding macros. Normally you
+start with a file but soon a macro is seen, and a next level of input is entered,
+because as part of the expansion more text can be met, files can be opened,
+other macros be expanded. When a macro expands a token register, another level is
+entered and the same happens when a \LUA\ call is triggered. Such a call can
+print back something to \TEX\ and that has to be scanned as if it came from a
+file.
+
+When token lists (and macros) get expanded, some commands result in direct
+actions, others result in expansion only and processing later as one of more
+tokens can end up in the input stack. The internals of the engine operate in
+miraculous ways. All commands trigger a function call, but some have their own
+while others share one with a switch statement (in \CCODE\ speak) because they
+belong to a category of similar actions. Some are expanded directly, some get
+delayed.
+
+Does it sound complicated? Well, it is. It's even more so when you consider that
+\TEX\ uses nesting, which means pushing and popping local assignments, knows
+modes, like horizontal, vertical and math mode, keeps track of interrupts and at
+the same type triggers typesetting, par building, page construction and flushing
+to the output file.
+
+It is for this reason plus the fact that users can and will do a lot to influence
+that behaviour that there is just one main loop and in many aspects global state.
+There are some exceptions, for instance when the output routine is called, which
+creates a sort of closure: it interrupts the process and for that reason gets
+grouping enforced so that it doesn't influence the main run. But even then the
+main loop does the job.
+
+Starting with version 1.10 \LUATEX\ provides a way to do a local run. There are
+two ways provided: expanding a token register and calling a \LUA\ function. It
+took a bit of experimenting to reach an implementation that works out reasonable
+and many variants were tried. In the appendix we give an example of usage.
+
+The current variant is reasonable robust and does the job but care is needed.
+First of all, as soon as you start piping something to \TEX\ that gets typeset
+you'd better in a valid mode. If not, then for instance glyphs can end up in a
+vertical list and \LUATEX\ will abort. In case you wonder why we don't intercept
+this: we can't because we don't know the users intentions. We cannot enforce a
+mode for instance as this can have side effects, think of expanding \type
+{\everypar} or injecting an indentation box. Also, as soon as you start juggling
+nodes there is no way that \TEX\ can foresee what needs to be copied to
+discarded. Normally it works out okay but because in \LUATEX\ you can cheat in
+numerous ways with \LUA, you can get into trouble.
+
+So, what has this to do with \METAPOST ? Well, first of all we could now use a
+one pass approach. The \type {textext} macro calls \LUA, which then let \TEX\ do
+some typesetting, and then gives back the dimensions to \METAPOST. The \quote
+{analyze} phase is now integrated in the run. For a regular text this works quite
+well because we just box some text and that's it. However, in the next section we
+will see where things get complicated.
+
+Let's summarize the one pass approach: the \type {textext} macro creates
+rectangle with the right dimensions and for doing passes the string to \LUA\
+using \type {runscript}. We store the argument of \type {textext} in a variable,
+then call \type {runtoks}, which expands the given token list, where we typeset a
+box with the stored text (that we fetch with a \LUA\ call), and the \type
+{runscript} passes back the three dimensions as fake \RGB\ color to \METAPOST\
+which applies a \type {scantokens} to the result. So, in principle there is no
+real conceptual difference except that we now analyze in|-|place instead of
+between runs. I will not show the code here because in \CONTEXT\ we use a wrapper
+around \type {runscript} so low level examples won't run well.
+
+\stopsection
+
+\startsection[title={Some aspects}]
+
+An important aspect of the text handling is that the whole text can be
+transformed. Normally this is only some scaling but rotation is also quite valid.
+In the first approach, the original \METAPOST\ one, we have pictures constructed
+of snippets and pictures transform well as long as the backend is not too
+confused, something that can happen when for instance very small or large font
+scales are used. There were some limitations with respect to the number of fonts
+and efficient inclusion when for instance randomization was used (I remember
+cases with thousands of font instances). The \PDF\ backend could handle most
+cases well, by just using one size and scaling at the \PDF\ level. All the \type
+{textext} approaches use rectangles as stubs which is very efficient and permits
+all transforms.
+
+How about color? Think of this situation:
+
+\starttyping
+\startMPcode
+    draw textext("some \color[red]{text}")
+        withcolor green ;
+\stopMPcode
+\stoptyping
+
+And what about the document color? We suffice by saying that this is all well
+supported. Of course using transparency, spot colors etc.\ also needs extensions.
+These are however not directly related to texts although we need to take it into
+account when dealing with the inclusion.
+
+\starttyping
+\startMPcode
+    draw textext("some \color[red]{text}")
+      withcolor "blue"
+      withtransparency (1,0.5) ;
+\stopMPcode
+\stoptyping
+
+What if you have a graphic with many small snippets of which many have the same
+content? These are by default shared, but if needed you can disable it. This makes
+sense if you have a case like this:
+
+\starttyping
+\useMPlibrary[dum]
+
+\startMPcode
+    draw textext("\externalfigure[unknown]") notcached ;
+    draw textext("\externalfigure[unknown]") notcached ;
+\stopMPcode
+\stoptyping
+
+Normally each unknown image gets a nice placeholder with some random properties.
+So, do we want these two to have the same or not? At least you can control it.
+
+When I said that things can get complicated with the one pass approach the
+previous code snippet is a good example. The dummy figure is generated by
+\METAPOST. So, as we have one pass, and jump temporarily back to \TEX,
+we have two problems: we reenter the \MPLIB\ instance again in the middle of
+a run, and we might pipe back something to and|/|or from \TEX\ nested.
+
+The first problem could be solved by starting a new \MPLIB\ session. This
+normally is not a problem as both runs are independent of each other. In
+\CONTEXT\ we can have \METAPOST\ runs in many places and some produce some more
+of less stand alone graphic in the text while other calls produce \PDF\ code in
+the backend that is used in a different way (for instance in a font). In the
+first case the result gets nicely wrapped in a box, while in the second case it
+might directly end up in the page stream. And, as \TEX\ has no knowledge of what
+is needed, it's here that we can get the complications that can lead to aborting
+a run when you are careless. But in any case, if you abort, then you can be sure
+you're doing the wrong thing. So, the second problem can only be solved by
+careful programming.
+
+When I ran the test suite on the new code, some older modules had to be fixed.
+They were doing the right thing from the perspective of intermediate runs and
+therefore independent box handling, putting a text in a box and collecting
+dimensions, but interwoven they demanded a bit more defensive programming. For
+instance, the multi|-|pass approach always made copies snippets while the one
+pass approach does that only when needed. And that confused some old code in a
+module, which incidentally is never used today because we have better
+functionality built|-|in (the \METAFUN\ \type {followtext} mechanism).
+
+The two pass approach has special code for cases where a text is not used.
+Imagine this:
+
+\starttyping
+picture p ; p := textext("foo") ;
+
+draw boundingbox p;
+\stoptyping
+
+Here the \quote {analyze} stage will never see the text because we don't flush p.
+However because \type {textext} is called it can also make sure we still know the
+dimensions. In the next case we do use the text but in two different ways. These
+subtle aspects are dealt with properly and could be made a it simpler in the
+single pass approach.
+
+\starttyping
+picture p ; p := textext("foo") ;
+
+draw p rotated 90 withcolor red ;
+draw p withcolor green ;
+\stoptyping
+
+\stopsection
+
+\startsection[title=One or two runs]
+
+So are we better off now? One problem with two passes is that if you use the
+equation solver you need to make sure that you don't run into the redundant
+equation issue. So, you need to manage your variables well. In fact you need to
+do that anyway because you can call out to \METAPOST\ many times in a run so old
+variables can interfere anyway. So yes, we're better off here.
+
+Are we worse off now? The two runs with in between the text processing is very
+robust. There is no interference of nested runs and no interference of nested
+local \TEX\ calls. So, maybe we're also bit worse off. You need to anyhow keep
+this in mind when you write your own low level \TEX|-|\METAPOST\ interaction
+trickery, but fortunately now many users do that. And if you did write your own
+plugins, you now need to make them single pass.
+
+The new code is conceptually cleaner but also still not trivial because due to
+the mentioned complications. It's definitely less code but somehow amputating the
+old code does hurt a bit. Maybe I should keep it around as reference of how text
+handling evolved over a few decades.
+
+\stopsection
+
+\startsection[title=Appendix]
+
+Because the single pass approach made me finally look into a (although somewhat
+limited) local \TEX\ run, I will show a simple example. For the sake of
+generality I will use \type {\directlua}. Say that you need the dimensions of a
+box while in \LUA:
+
+\startbuffer
+\directlua {
+    tex.sprint("result 1: <")
+
+    tex.sprint("\\setbox0\\hbox{one}")
+    tex.sprint("\\number\\wd0")
+
+    tex.sprint("\\setbox0\\hbox{\\directlua{tex.print{'first'}}}")
+    tex.sprint(",")
+    tex.sprint("\\number\\wd0")
+
+    tex.sprint(">")
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This looks ok, but only because all printed text is collected and pushed into a
+new input level once the \LUA\ call is done. So take this then:
+
+\startbuffer
+\directlua {
+    tex.sprint("result 2: <")
+
+    tex.sprint("\\setbox0\\hbox{one}")
+    tex.sprint(tex.getbox(0).width)
+
+    tex.sprint("\\setbox0\\hbox{\\directlua{tex.print{'first'}}}")
+    tex.sprint(",")
+    tex.sprint(tex.getbox(0).width)
+
+    tex.sprint(">")
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This time we get the widths of the box known at the moment that we are in \LUA,
+but we haven't typeset the content yet, so we get the wrong dimensions. This
+however will work okay:
+
+\startbuffer
+\toks0{\setbox0\hbox{one}}
+\toks2{\setbox0\hbox{first}}
+\directlua {
+    tex.forcehmode(true)
+
+    tex.sprint("<")
+
+    tex.runtoks(0)
+    tex.sprint(tex.getbox(0).width)
+
+    tex.runtoks(2)
+    tex.sprint(",")
+    tex.sprint(tex.getbox(0).width)
+
+    tex.sprint(">")
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+as does this:
+
+\startbuffer
+\toks0{\setbox0\hbox{\directlua{tex.sprint(MyGlobalText)}}}
+\directlua {
+    tex.forcehmode(true)
+
+    tex.sprint("result 3: <")
+
+    MyGlobalText = "one"
+    tex.runtoks(0)
+    tex.sprint(tex.getbox(0).width)
+
+    MyGlobalText = "first"
+    tex.runtoks(0)
+    tex.sprint(",")
+    tex.sprint(tex.getbox(0).width)
+
+    tex.sprint(">")
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+Here is a variant that uses functions:
+
+\startbuffer
+\directlua {
+    tex.forcehmode(true)
+
+    tex.sprint("result 4: <")
+
+    tex.runtoks(function()
+        tex.sprint("\\setbox0\\hbox{one}")
+    end)
+    tex.sprint(tex.getbox(0).width)
+
+    tex.runtoks(function()
+        tex.sprint("\\setbox0\\hbox{\\directlua{tex.print{'first'}}}")
+    end)
+    tex.sprint(",")
+    tex.sprint(tex.getbox(0).width)
+
+    tex.sprint(">")
+}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+The \type {forcemode} is needed when you do this in vertical mode. Otherwise the
+run aborts. Of course you can also force horizontal mode before the call. I'm
+sure that users will be surprised by side effects when they really use this
+feature but that is to be expected: you really need to be aware of the subtle
+interference of input levels and mix of input media (files, token lists, macros
+or \LUA) as well as the fact that \TEX\ often looks one token ahead, and often,
+when forced to typeset something, also can trigger builders. You're warned.

+\startchapter[title={Conditions}]
+
+In case you wonder why we have modes in \CONTEXT, here is an example that might
+convince you. The \TEX\ language has conditionals and they are in fact quite
+efficient, take for instance:
+
+\startTEX
+\ifnum\scratchcounter>10
+    \ifdim\scratchdimen>10pt
+        one
+    \else
+        two
+    \fi
+\else
+    three
+\fi
+\stopTEX
+
+When the first test fails, \TEX\ will do a fast scan over the following tokens
+and expand the \type {three} branch. In order to do such a fast scan, the nested
+condition needs to be properly balanced: the \type {\else} is optional but the
+nested \type {\fi} definitely isn't. Now imagine that you use a few pseudo
+booleans, like:
+
+\startTEX
+\newif\ifalpha \alphatrue
+\newif\ifbeta  \betatrue
+\stopTEX
+
+And you need it in:
+
+\startTEX
+\ifalpha
+    \ifbeta
+        YES
+    \else
+        NOP
+    \fi
+\else
+    NOP
+\fi
+\stopTEX
+
+This happens occasionally in real applications and one can either repeat the
+\type {NOP} or wrap it in a macro in order to save tokens. However, way more
+natural would be something like this:
+
+\startTEX
+\ifalphaorbeta
+    YES
+\else
+    NOP
+\fi
+\stopTEX
+
+This basically would introduce a new kind concept: an expandable macro flagged as
+\type {\if} kind of token. I actually experimented with that in \LUATEX\ but
+rejected it eventually. Instead \type {\ifcondition} was introduced. This is
+basically equivalent to \type {\iffalse} when \TEX\ is in fast \type {\if*}
+skipping mode, but when a real test happens the next argument is expanded. That
+macro is expected to end up as something equivalent to \type {\iftrue} or \type
+{\iffalse} so that other the nexct branch or the \type {\else} is entered. Here
+is an example:
+
+\startTEX
+\ifcondition\alphaorbeta
+    YES
+\else
+    NOP
+\fi
+\stopTEX
+
+There are several ways to define \type {\alphaorbeta} now and we show a few here.
+It's up to you to figure out which ons is the most efficient.
+
+\startTEX
+\def\alphaorbeta{\ifcase0\ifalpha \else\ifbeta \else1\fi\fi\relax}
+\def\alphaorbeta{\ifcase \ifalpha0\else\ifbeta0\else1\fi\fi\relax}
+\def\alphaorbeta{\ifnum1=\ifalpha1\else\ifbeta1\else0\fi\fi\relax}
+\def\alphaorbeta{\ifnum 0\ifalpha1\fi  \ifbeta1\fi       >1\relax}
+\stopTEX
+
+Now, do we expect users to come up with such constructs? Of course not. Even in
+\CONTEXT\ we don't really need them, although there are a few places where they
+can be used. In \CONTEXT\ you would just do this:
+
+\startTEX
+\enablemode[alpha]
+\enablemode[beta]
+
+\doifelsemode {alpha,beta} {
+    YES
+} {
+    NOP
+}
+\stopTEX
+
+Of course such a verbose macro is less efficient but even if you use this test
+10.000 times in a run it will not take more than 0.06 seconds on a decent 2013
+laptop.

+\startchapter[title={Leaders}]
+
+The following example comes from a question on the \CONTEXT\ list. It
+exhibits a few low level tricks. For the purpose of this example we
+use \type {\ruledhbox} instead of \type {\hbox}. We start with a simple
+command that puts something at the end of a line:
+
+\startbuffer
+\starttexdefinition MyFill #1
+    \removeunwantedspaces
+    \hfill
+    \ruledhbox{#1}
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+We use this in:
+
+\startbuffer[sample]
+\startitemize[packed,joinedup][rightmargin=3em]
+    \startitem
+        \samplefile{ward}\MyFill{DW}
+    \stopitem
+\stopitemize
+\stopbuffer
+
+\typebuffer[sample][option=TEX]
+
+and get:
+
+\getbuffer[sample]
+
+But, the requirement was that we move the number towards the right margin, so
+instead we need something:
+
+\startbuffer
+\starttexdefinition MyFill #1
+    \removeunwantedspaces
+    \hfill
+    \rlap{\ruledhbox to \rightskip{\hss#1}}
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+This already looks more like it:
+
+\getbuffer[sample]
+
+But also part of the requirements was that there should be dots between the end
+of the last sentence and the number. In low level \TEX\ speak that means using
+leaders: repeated boxed content where the repitition is driven by a glue
+specification. Let's naively use leaders now:
+
+\startbuffer
+\starttexdefinition MyFill #1
+    \leaders
+        \ruledhbox to 1em{\hss.\hss}
+        \hfill
+    \ruledhbox{#1}
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+Let's see what we get:
+
+\getbuffer[sample]
+
+Again we need to move the number to the right. This time we need a different
+solution because we need to fill the space in between. When \TEX\ ends a
+paragraph it adds \type {\parfillskip} so we will now manipulate that parameter.
+
+\startbuffer
+\starttexdefinition MyFill #1
+    \parfillskip-1\rightskip plus 1fil\relax
+    \leaders
+        \ruledhbox to 1em{\hss.\hss}
+        \hfill
+    \ruledhbox{#1}
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+Does it look better?
+
+\getbuffer[sample]
+
+Indeed it does, but watch this:
+
+\startbuffer[sample]
+\startitemize[packed,joinedup][rightmargin=8.5em]
+    \startitem
+        \samplefile{ward}\MyFill{DW}\par
+        \samplefile{ward}\par
+        \samplefile{ward}\MyFill{DW}
+    \stopitem
+\stopitemize
+\stopbuffer
+
+\typebuffer[sample][option=TEX]
+
+The first \type {\MyFill} will set the \type {\parfillskip} to a value that will
+also be used later on.
+
+\getbuffer[sample]

+The way out is the following
+
+\startbuffer
+\starttexdefinition MyFill #1
+    \begingroup
+    \parfillskip-1\rightskip plus 1fil\relax
+    \leaders
+        \ruledhbox to 1em{\hss.\hss}
+        \hfill
+    \ruledhbox{#1}
+    \par
+    \endgroup
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+This looks more or less okay. The \type {\par} keeps the adaption local but for
+it to work well, the \type {\par} must be inside the group.
+
+\getbuffer[sample]
+
+Now it's time to go for perfection! First of all, we get rid of any leading
+spacing. If we need some we should inject it after a cleanup. We also use a
+different leader command. Instead of \type {to} we use a \type {spread} so that
+we get half the emwidth and not something slightly less due to the width of the
+period.
+
+\startbuffer
+\starttexdefinition MyFill #1
+    \removeunwantedspaces

+\stoptexdefinition
+\stopbuffer

+\typebuffer[option=TEX] \getbuffer

+        \samplefile{sapolsky}\MyFill{RS}\par
+    \stopitem
+\stopitemize
+\stopbuffer
+
+\getbuffer[sample]
+
+For which we used this:
+
+\typebuffer[sample][option=TEX]
+
+Finally we get rid of the tracing:
+
+\startbuffer
+\starttexdefinition unexpanded MyFill #1
+    \begingroup
+    \parfillskip-1\rightskip plus 1fil\relax
+    \leaders
+        \hbox to \emwidth{\hss.\hss}

+    \hbox{#1}
+    \par
+    \endgroup
+\stoptexdefinition
+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+Watch a few more details. It brings us to:

+    \endgroup

+\stopbuffer
+
+\typebuffer[option=TEX] \getbuffer
+
+\getbuffer[sample]
+
+When writing these examples I realized that it's rather trivial to add this
+option to the already existing filler mechanism. The definition of such a filler
+looks like this:

+\startbuffer
+\definefiller
+  [MyFiller]
+  [offset=.25\emwidth,

+    \stopitem
+\stopitemize
+\stopbuffer
+
+The sample code now becomes:
+
+\typebuffer[sample][option=TEX]
+
+Ans as expected renders as:

+
+\startchapter[title={Lookahead}]
+
+When you look at the \TEX\ source of a macro package, your can often see
+constructs like this:
+
+\startTEX
+\def\foo#1%
+  {We do something with  "#1".}
+\stopTEX
+
+or maybe:
+
+\startTEX
+\def\foo#1{%
+    We do something with  "#1".%
+}
+\stopTEX
+
+Normally the percentage symbol is used to indicate a comment, but here
+are no comments. In these cases, it makes the definition effectively
+
+\startTEX
+\def\foo#1{do something with "#1"!}
+\stopTEX
+
+which is different from when we would not have that percent sign there:
+
+\startTEX
+\def\foo#1 {We do something with "#1"!}
+\stopTEX
+
+That variant is valid \TEX\ code but expects a space as delimiter of the
+argument to \type {\foo}. This means that you can say:
+
+\startTEX
+\foo{1} \foo 2 \foo {34} and \foo 56 .
+\stopTEX
+
+while this can trigger an error message (when no space is seen at some point) or
+at least give unexpected results.
+
+\startTEX
+\foo{1}\foo 2\foo {34}and\foo 56.
+\stopTEX
+
+A different use of the percent is seen in cases like this:
+
+\startTEX
+\def\foo#1%
+  {We do something %
+   with "#1".}
+\stopTEX
+
+This time we want to preserve the space after \type {something} because an
+end|-|of|-|line would either or not collapse it with \type {with} depending on
+how the endofline character is set up. Normally
+
+\startTEX
+\def\foo#1%
+  {We do something
+   with "#1".}
+\stopTEX
+
+will also add a space after something but when \TEX\ is set up to ignore lines
+you get a collapse. So the explicit space is a robust way out. Both cases of
+using or omitting the comment symbol are easy to spot as they trigger an error
+or result in weird typeset results.
+
+\startbuffer[defs]
+\def\fooA#1%
+  {\ifnum#1>100
+     yes\else nop%
+   \fi}
+
+\def\fooB#1{\ifnum#1>100 yes\else nop \fi}
+
+\def\fooC#1%
+  {\ifnum#1>100%
+     yes\else nop%
+   \fi}
+\stopbuffer
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+We test this with:
+
+\startbuffer[demo]
+\fooA{100} \fooB{100} \fooC{100}
+\fooA{101} \fooB{101} \fooC{101}
+\stopbuffer
+
+\typebuffer[demo][option=TEX]
+
+And the result is probably what you expect:
+
+\startlines
+\getbuffer[demo]
+\stoplines
+
+\startbuffer[defs]
+\def\fooA#1%
+  {\ifnum#1>100
+     1\else 0%
+   \fi}
+
+\def\fooB#1{\ifnum#1>100 1\else 0\fi}
+
+\def\fooC#1%
+  {\ifnum#1>100%
+     1\else 0%
+   \fi}
+\stopbuffer
+
+However, when we have the following macro body:
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+We get this output. Do you see the issue?
+
+\startlines
+\getbuffer[demo]
+\stoplines
+
+A preferred way to catch this is the following as a \type {\relax} ends scanning
+for a number:
+
+\startbuffer[defs]
+\def\foo#1%
+  {\ifnum#1>100\relax
+     1\else 0%
+   \fi}
+\stopbuffer
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+However, watch what happens here:
+
+\startbuffer[demo]
+\edef\result{\foo{123}}
+\stopbuffer
+
+\typebuffer[demo][option=TEX] \getbuffer[demo]
+
+The \type {\result} macro has the following body:
+
+\expanded{\setbuffer[result]\meaning\result\endbuffer}
+
+\typebuffer[result][option=TEX]
+
+A neat trick out of this is the following:
+
+\startbuffer[defs]
+\def\foo#1%
+  {\ifnum#1>\numexpr100\relax
+     1\else 0%
+   \fi}
+\stopbuffer
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+\getbuffer[demo]
+
+Now the body of \type {\result} looks like this:
+
+\expanded{\setbuffer[result]\meaning\result\endbuffer}
+
+\typebuffer[result][option=TEX]
+
+Of course this also works:
+
+\startTEX
+\def\foo#1%
+  {\ifnum#1>100 %
+     1\else 0%
+   \fi}
+\stopTEX
+
+as a space also delimits scanning the number. But that method can actually introduce
+that space in the output. Think of this definition:
+
+\startbuffer[defs]
+\def\foo#1#2%
+  {\ifnum#1>#2 %
+     1\else 0%
+   \fi}
+\stopbuffer
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+What if \type {#2} has a trailing space? What if it is a verbose number? What if
+it is a counter variable?
+
+\startbuffer[demo]
+\scratchcounter=100
+    [\foo{101}{100}] [\foo{101}{100 }] [\foo{101}\scratchcounter]
+\scratchcounter=101
+    [\foo{100}{101}] [\foo{100}{101 }] [\foo{100}\scratchcounter]
+\stopbuffer
+
+\typebuffer[demo][option=TEX]
+
+\startlines
+\getbuffer[demo]
+\stoplines
+
+If you really want to introduce an unpredictable situation, use a coding style like
+this:
+
+\startTEX
+\def\foo#1#2#3#4{\if#1=#2#3\else#4\fi}
+\stopTEX
+
+This is not that imaginary as you often see users play safe and do things like this:
+
+\startTEX
+\ifnum\scratchcounterone=\scratchcountertwo%
+    ...
+\else
+    ...
+\fi
+\stopTEX
+
+Here the percent sign is useless as the number scanner already got the number,
+just try:
+
+\startTEX
+\scratchcounterone=1
+\scratchcountertwo=1
+
+\ifnum\scratchcounterone=\scratchcountertwo
+    yes
+\else
+    nop
+\fi
+\stopTEX
+
+A previous one liner formatted like this really is not better!
+
+\startTEX
+\def\foo#1#2#3#4%
+  {\ifnum#1=#2%
+      #3%
+   \else
+      #4%
+   \fi}
+\stopTEX
+
+When you define macros more often than not you don't want unexpected spaces (aka spurious spaces)
+which is why in \CONTEXT\ for instance setups ignores lines:
+
+\startbuffer[defs]
+\startsetups foo
+    here
+    we ignore
+    spaces at the end
+    of a line
+\stopsetups
+\stopbuffer
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+so we get: \quotation {\directsetup{foo}} which means that the normally few times
+that we {\em do} want spaces we need to be explicit:
+
+\startbuffer[defs]
+\startsetups foo
+    here\space
+    we ignore\space
+    spaces at the end\space
+    of a line\space
+\stopsetups
+\stopbuffer
+
+\typebuffer[defs][option=TEX] \getbuffer[defs]
+
+Now we're okay: \quotation {\directsetup{foo}}. The same is true for:
+
+\startTEX
+\starttexdefinition foo
+    here\space
+    we ignore\space
+    spaces at the end\space
+    of a line\space
+\stoptexdefinition
+\stopTEX
+
+There are more cases where \TEX\ will look further. Take for example skip (glue)
+scanning. A glue specification can have \type {plus} and \type {minus} fields.
+
+\startbuffer[defs]
+\scratchdimenone=10pt
+\scratchskipone =10pt plus 10pt minus 10pt
+\scratchskiptwo =0pt
+\stopbuffer
+
+\typebuffer[defs][option=TEX]
+
+Now take the following test:
+
+\startbuffer[demo]
+{1 \scratchskiptwo  10pt             plus 10pt \relax\the\scratchskiptwo}
+{2 \scratchskiptwo  \scratchdimenone plus 10pt \relax\the\scratchskiptwo}
+{3 \scratchskiptwo 1\scratchdimenone plus 10pt \relax\the\scratchskiptwo}
+{4 \scratchskiptwo  \scratchskipone  plus 10pt \relax\the\scratchskiptwo}
+{5 \scratchskiptwo 1\scratchskipone  plus 10pt \relax\the\scratchskiptwo}
+\stopbuffer
+
+\typebuffer[demo][option=TEX]
+
+\startlines
+\inlinebuffer[defs]\getbuffer[demo]
+\stoplines
+
+If you wonder what the second \type {\relax} does, here is a variant:
+
+\startlines
+{1 \scratchskiptwo  10pt             plus 10pt \the\scratchskiptwo}
+{2 \scratchskiptwo  \scratchdimenone plus 10pt \the\scratchskiptwo}
+{3 \scratchskiptwo 1\scratchdimenone plus 10pt \the\scratchskiptwo}
+{4 \scratchskiptwo  \scratchskipone  plus 10pt \the\scratchskiptwo}
+{5 \scratchskiptwo 1\scratchskipone  plus 10pt \the\scratchskiptwo}
+\stoplines
+
+\typebuffer[demo][option=TEX]
+
+\startlines
+\inlinebuffer[defs]\getbuffer[demo]
+\stoplines
+
+In this second variant \TEX\ happily keep looking for a glue specification when
+it sees the \type {\the} so it serializes \type {\scratchskiptwo}. But as it sees
+\type {0pt} then, it stops scanning the glue spec. What we get typeset is the old
+value, not the new one! If you want to prevent this you need to \type {\relax}.
+
+Another case where \TEX\ keeps scanning is the following:
+
+\startbuffer[demo]
+\vrule width 40pt height 2pt depth 5pt \quad
+\vrule width 40pt height 20pt depth 5pt height 10pt \quad
+\vrule width 40pt height 10pt height 20pt \quad
+\vrule width 40pt height 20pt depth 5pt height 10pt width 80pt
+\stopbuffer
+
+\typebuffer[demo][option=TEX]
+
+This gives the rules:
+
+\startlinecorrection \darkgray
+\getbuffer[demo]
+\stoplinecorrection
+
+So you can overload dimensions. The space before the \type {quad} is gobbled as
+part of the look ahead for more keywords.
+
+Often rules (just like glue assignments) are wrapped in macro definitions where the
+macro writer used \type {\relax} to look ahead. That way you prevent an error message
+in cases like:
+
+\startTEX
+\def\foo{\vrule width 40pt height 2pt}
+
+The \foo depth of this thought is amazing.
+\stopTEX
+
+because \type {of} definitely is not a valid dimension. Even more subtle is:
+
+\startTEX
+\def\foo{\hskip 10pt plus 1fil}
+
+The \foo fine points of typesetting can actually become a nightmare.
+\stopTEX
+
+As \TEX\ will now see the \type {f} of \type {fine} as further specification and
+think that you want \type {1fill}.
+
+So, the most important lesson of this chapter is that you need to be aware of the way
+\TEX\ scans for quantities and specifications. In most cases the users can safely use
+a \type {\relax} to prevent a lookahead. And try to avoid adding percent signs all
+over the place.

+As you can see here, various directives (and even some trackers) have optional

+of this article, but you can look them up in the \CONTEXT\ source by searching
+for \typ {directives.register} and \typ {trackers.register}.
+
+In verbose mode, \sMTXRUN\ itself gives more messages, and it also \typ
+{resolvers.locating}, which is a tracker itself:

+\startsubsection[title=Setup for finding files and configurations]
+
+The next block of options deals with the setup of \sMTXRUN\ itself. You do not
+need to deal with these options unless you are messing with the \CONTEXT\
+distribution yourself instead of relying on a prepackaged solution, or you need
+to use kpathsea for some reason (typically in a \MKII\ environment). In
+particular, \type {--progname} and \type {--tree} are often needed as well when
+using the \type {kpse} options.

+
+\startsubsection[title=Running code]
+
+Here we come to the core functionality of \sMTXRUN: running scripts. First
+there are few options that trigger how the running takes place:
+
+\startoptions
+    \option
+        {path=runpath}
+        {go to given path before execution}
+    \option
+        {ifchanged=filename}
+        {only execute when given file has changed (this loads and saves an md5
+         checksum from \type {filename.md5})}
+    \option
+        {iftouched=old,new}
+        {only execute when given file has changed (time stamp)}
+    \option
+        {timedrun}
+        {run a script or program and time its run (external)}
+\stopoptions
+
+Specifying both \type {--iftouched} and \type {--ifchanged} means both are
+tested, and when either one is false, nothing will happen. These options have to
+come before one of the next options:
+
+\startoptions
+    \option
+        {script}
+        {run an mtx script (where \LUA\ is the preferred method); it has the
+         sub||options \typ {--nofiledatabase}, \typ {--autogenerate}, \type
+         {--load}, and \type {--save}. The latter two are currently no|-|ops}
+    \option
+        {execute}
+        {run a script or program externally (\type {texmfstart} method); it has
+         sub||option \type {--noquotes}}
+    \option
+        {internal}
+        {run a script using built|-|in libraries (alias is \type {--ctxlua})}
+    \option
+        {direct}
+        {run an external program; it has the sub||option \type {--noquotes}}
+\stopoptions
+
+Since scripts potentially have their own options, any options intended for
+\sMTXRUN\ itself have to come {\it before} the option that specifies the script
+to run, and options for the script itself have to come {\it after} the option
+that gives the script name. This is especially true when using \type {--script},
+so it is important to check the order of your options.
+
+Of the four above options, \type {--script} is the most important one, since that
+is the one that finds and executes the \LUA\ \sMTXRUN\ scripts provided by the
+distribution. With \typ {--nofiledatabase}, it will not attempt to resolve any
+file names (which means you need either a local script or a full path name). On
+the opposite side, when you also provide \typ {--autogenerate}, it will not only
+attempt to resolve the file name, it will also regenerate the database if it
+cannot find the script on the first try. In a future version of \CONTEXT, the
+\type {--load} and \type {--save} will allow you to save|/|restore the current
+command line in a file for reuse.
+
+The shell return value of \sMTXRUN\ indicates whether the script was found. When
+you specify something like \type {--script base}, \sMTXRUN\ actually searches
+for \type {mtx-base.lua}, \type {mtx-bases.lua}, \type {mtx-t-base.lua}, \type
+{mtx-t-bases.lua}, and \type {base.lua}, in that order. The
+distribution||supplied scripts normally use \type {mtx-<name>.lua} as template.
+The template names with \type {mtx-t-} prefix is reserved for third||party
+scripts, and \type {<name>.lua} is just a last-ditch effort if nothing else
+works. Scripts are looked for in the local path, and in whatever directories the
+configuration variable \type {LUAINPUTS} points to.
+
+The \type {--execute} options exists mostly for the non||\LUA\ {\MKII} scripts
+that still exist in the distribution. It will try to find a matching interpreter
+for non||\LUA\ scripts, and it is aware of a number of distribution||supplied
+scripts so that if you specify \type {--execute texexec}, it knows that what you
+really want to execute is \type {ruby texexec.rb}. Support is present for \RUBY\
+(\type {.rb}, \LUA\ (\type {.lua}), python (\type {.py}) and \PERL\ (\type {.pl})
+scripts (tested in that order). File resolving uses \type {TEXMFSCRIPTS} from the
+configuration. The shell return value of \sMTXRUN\ indicates whether the script
+was found and executed.
+
+The \type {--internal} option uses the file search method of \type {--execute},
+but then assumes this is a \LUA\ script and executes it internally like \type
+{--script}. This is useful if you have a \LUA\ script in an odd location.
+
+The last of the four options, \type {--direct}, directly executes an external
+program. You need to give the full path for binaries not in the current shell
+\type {PATH}, because no searching is done at all. The shell return value of
+\sMTXRUN\ in this case is a boolean based on the return value of
+\type {os.exec()}.
+
+It is also possible to execute bare \LUA\ code directly:
+
+\startoptions
+    \option
+        {evaluate}
+        {run code passed on the command-line (between quotes)}
+\stopoptions
+
+\stopsubsection
+
+\startsubsection[title=Options for maintenance of \sMTXRUN\ itself]
+
+None of these are advertised. Normally developers should be the only ones needing
+them, but if you made a change to one of the distributed libraries (maybe because
+of a beta bug), you may need to run \type {--selfmerge} and \type {--selfupdate}.
+
+\startoptions
+    \option
+        {selfclean}
+        {remove embedded libraries}
+    \option
+        {selfmerge}
+        {update embedded libraries in \type {mtxrun.lua}}
+    \option
+        {selfupdate}

+
+\startsubsection[title=Creating stubs]
+
+Stubs are little shortcuts that live in some binaries directory. For example, the
+content of the \UNIX||style \sCONTEXT\ shell command is:
+
+\starttyping
+#!/bin/sh
+mtxrun --script context "$@"
+\stoptyping
+
+Apart from the \sCONTEXT\ command itself (which is provided by the distribution),
+use of stubs is discouraged. Still, the \sMTXRUN\ options are there because
+sometimes existing workflows depend on executable tool names like \type
+{ctxtools}.
+
+\startoptions
+    \option
+        {makestubs}
+        {create stubs for (context related) scripts}

+\startsubsection[title=Remaining options]

+The remaining options are hard to group into a subcategory. These are the
+advertised options:
+
+\startoptions
+    \option
+        {systeminfo}
+        {show current operating system, processor, et cetera}
+    \option
+        {edit}

+\startsubsection[title=Known scripts]
+
+When you run \type {mtxrun --scripts}, it will output a list of \quote {known}
+scripts. The definition of \quote {known} is important here: the list comprises
+the scripts that are present in the same directory as \type {mtx-context.lua}
+that do not have an extra hyphen in the name (like \type {mtx-t-...}scripts would
+have). In a normal installation, this means it \quote {knows} almost all the
+scripts that are distributed with \CONTEXT. Note: it skips over any files from
+the distribution that do have an extra hyphen, like the \type {mtx-server}
+support scripts.
+
+Since this section is about \sMTXRUN, I'll just present the list of the scripts
+that are \quote {known} in the current \CONTEXT\ beta as output by \sMTXRUN\
+itself, and not get into detail about all of the script functionality (they all
+have \type {--help} options if you want to find out more). Where we still felt the
+need to explain something, there is an extra bit of text in italics.

+\startsubsection[title=Writing your own]
+
+A well|-|written script has some required internal structure. It should start with
+a module definition block. This gives some information about the module, but more
+importantly, it prevents double|-|loading.
+
+Here is an example:
+
+\starttyping
+if not modules then modules = { } end
+
+modules ['mtx-envtest'] = {
+    version   = 0.100,
+    comment   = "companion to mtxrun.lua",
+    author    = "Taco Hoekwater",
+    copyright = "Taco Hoekwater",
+    license   = "bsd"
+}
+\stoptyping
+
+Next up is a variable containing the help information. The help information is actually
+a bit of \XML\ stored in \LUA\ string. In the full example listing at the end of this
+article, you can see what the internal structure is supposed to be like.
+
+\starttyping
+local helpinfo = [[
+<?xml version="1.0"?>
+<application>
+  ....
+</application>
+]]
+\stoptyping
+
+And this help information is then used to create an instance of an \type
+{application} table.
+
+\starttyping
+local application = logs.application {
+    name     = "envtest",
+    banner   = "Mtxrun environment demo",
+    helpinfo = helpinfo,
+}
+\stoptyping
+
+After this call, the \type {application} table contains (amongst some other
+things) three functions that are very useful:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {identify()}
+    {Prints out a banner identifying the current script to the user.}
+\mtxrunenv
+    {report(str)}
+    {For printing information to the terminal with the script name as prefix.}
+\mtxrunenv
+    {export()}
+    {Prints the \type {helpinfo} to the terminal, so it can easily be used for
+     documentation purposes.}
+\stopmtxrunenvironment
+
+Next up, it is good to define your scripts' functionality in functions in a
+private table. This prevents namespace pollution, and looks like this:
+
+\starttyping
+scripts          = scripts         or { }
+scripts.envtest  = scripts.envtest or { }
+
+function scripts.envtest.runtest()
+    application.report("script name is " .. environment.ownname)
+end
+\stoptyping
+
+An finally, identify the current script, followed by handling the provided
+options (usually with an \type {if}||\type {else} statement).
+
+\starttyping
+if environment.argument("exporthelp") then
+   application.export()
+elseif environment.argument('test') then
+   scripts.envtest.runtest()
+else
+    application.help()
+end
+\stoptyping
+
+\stopsubsection
+
+\startsubsection[title=Script environment]

+\sMTXRUN\ includes lots of the internal \LUA\ helper libraries from \CONTEXT. We
+actually maintains a version of the script without all those libraries included,

+In fact, the \LUA\ table \type {own} contains some other useful stuff like the
+script's actual disk name and location (\type {own.name} and \type {own.path})
+and some internal variables like a list of all the locations it searches for its
+embedded libraries (\type {own.list}), which is used by the \type {--selfmerge}
+option and also allows the non||amalgamated version to run (since otherwise \type
+{--selfmerge} could not be bootstrapped).
+
+\sMTXRUN\ offers a programming environment that makes it easy to write \LUA\ a
+scripts. The most important element of that environment is a \LUA\ table that is
+conveniently called \type {environment} (\type {util-env} does the actual work of
+setting that up).
+
+The bulk of \type {environment} consists of functions and variables that deal
+with the command||line given by the user as \sMTXRUN\ does quite a bit of work on
+the given command||line. The goal is to safely tuck all the given options into
+the \type {arguments} and \type {files} tables. This work is done by two
+functions called \type {initializearguments()} and \type {splitarguments()}.
+These functions are part of the \type{environment} table, but you should not need
+them as they have been called already once control is passed on to your script.
+
+\startmtxrunenvironment
+\mtxrunenv
+    {arguments}
+    {These are the processed options to the current script. The keys are option
+     names (without the leading dashes) and the value is either \type {true} or a
+     string with one level of shell quotes removed.}
+\mtxrunenv
+    {files}
+    {This array holds all the non||option arguments to the current script.
+     Typically, those are supposed to be files, but they could be any text,
+     really.}
+\mtxrunenv
+    {getargument(name,partial)}
+    {Queries the \type {arguments} table using a function. Its main reason for
+     existence is the \type {partial} argument, which allows scripts to accept
+     shortened command||line options (alias: \type {argument()}).}
+\mtxrunenv
+    {setargument(name,value)}
+    {Sets a value in the \type {arguments} table. This can be useful in
+     complicated scripts with default options.}
+\stopmtxrunenvironment
+
+In case you need access to the full command||line, there are some possibilities:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {arguments_after}
+    {These are the unquoted but otherwise unprocessed arguments to your script as
+     an array.}
+\mtxrunenv
+    {arguments_before}
+    {These are the unquoted but otherwise unprocessed arguments to \sMTXRUN\
+     before your scripts' name (so the last entry is usually \type {--script}).}
+\mtxrunenv
+    {rawarguments}
+    {This is the whole unprocessed command||line as an array.}
+\mtxrunenv
+    {originalarguments}
+    {Like \type{rawarguments}, but with some top||level quotes removed.}
+\mtxrunenv
+    {reconstructcommandline(arg,noquote)}
+    {Tries to reconstruct a command||line from its arguments. It uses \type
+     {originalarguments} if no \type {arg} is given. Take care: due to the
+     vagaries of shell command||line processing, this may or may not work when
+     quoting is involved.}
+\stopmtxrunenvironment
+
+\type{environment} also stores various bits of information you may find useful:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {validengines}
+    {This table contains keys for \type {luatex} and \type {luajittex}. This is
+     only relevant when \sMTXRUN\ itself is called via \LUATEX's \type {luaonly}
+     option.}
+\mtxrunenv
+    {basicengines}
+    {This table maps executable names to \type{validengines} entries.}
+\mtxrunenv
+    {default_texmfcnf}
+    {This is the \type {texmfcnf} value from \type {kpathsea}, processed for use
+     with \MKIV\ in the unlikely event this is needed.}
+\mtxrunenv
+    {homedir}
+    {The user's home directory.}
+\mtxrunenv
+    {ownbin}
+    {The name of the binary used to call \sMTXRUN.}
+\mtxrunenv
+    {ownmain}
+    {The mapped version of \type {ownbin}.}
+\mtxrunenv
+    {ownname}
+    {Full name of this instance of \sMTXRUN.}
+\mtxrunenv
+    {ownpath}
+    {The path this  instance of \sMTXRUN\ resides in.}
+\mtxrunenv
+    {texmfos}
+    {Operating system root directory path.}
+\mtxrunenv
+    {texos}
+    {Operating system root directory name.}
+\mtxrunenv
+    {texroot}
+    {\CONTEXT\ root directory path.}
+\stopmtxrunenvironment
+
+As well as some functions:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {texfile(filename)}
+    {Locates a {\TEX} file.}
+\mtxrunenv
+    {luafile(filename)}
+    {Locates a \LUA\ file.}
+\mtxrunenv
+    {loadluafile(filename,version)}
+    {Locates, compiles and loads a \LUA\ file, possibly in compressed \type {.luc}
+     format. In the compressed case, it uses the \type {version} to make sure the
+     compressed form is up||to||date.}
+\mtxrunenv
+    {luafilechunk(filename,silent,macros)}
+    {Locates and compiles a \LUA\ file, returning its contents as data.}
+\mtxrunenv

+    {Creates a format file and stores in in the \CONTEXT\ cache, used by \type

+\mtxrunenv

+    {Returns a modified version of \type {root} based on the relative path in

+\stopmtxrunenvironment
+
+\stopsubsection
+
+\startsubsection[title=Shell return values]
+
+As explained earlier, the shell return value of \sMTXRUN\ normally indicates
+whether the script was found. If you are running a \CONTEXT\ release newer than
+September 2018 and want to modify the shell return value from within your script,
+you can use \type {os.exitcode}. Whatever value you assign to that variable will
+be the shell return value of your script.

+\startchapter[title={Commands}]

+\startsection[title={nodes and lpaths}]
+
+The amount of commands available for manipulating the \XML\ file is rather large.
+Many of the commands cooperate with the already discussed setups, a fancy name
+for a collection of macro calls either or not mixed with text.
+
+Most of the commands are just shortcuts to \LUA\ calls, which means that the real
+work is done by \LUA. In fact, what happens is that we have a continuous transfer
+of control from \TEX\ to \LUA, where \LUA\ prints back either data (like element
+content or attribute values) or just invokes a setup whereby it passes a
+reference to the node resolved conform the path expression. The invoked setup
+itself might return control to \LUA\ again, etc.
+
+This sounds complicated but examples will show what we mean here. First we
+present the whole repertoire of commands. Because users can read the source code,
+they might uncover more commands, but only the ones discussed here are official.
+The commands are grouped in categories.
+
+In the following sections \cmdinternal {cd:node} means a reference to a node:
+this can be the identifier of the root (the loaded xml tree) or a reference to a
+node in that tree (often the result of some lookup. A \cmdinternal {cd:lpath} is
+a fancy name for a path expression (as with \XSLT) but resolved by \LUA.
+
+\stopsection
+
+\startsection[title={commands}]
+
+There are a lot of commands available but you probably can ignore most of them.
+We try to be complete which means that there is for instance \type {\xmlfirst} as
+well as \type {\xmllast} but you probably never need the last one. There are also
+commands that were used when testing this interface and we see no reason to
+remove them. Some obscure ones are used in modules and after a while even I often
+forget that they exist. To give you an idea of what commands are important we
+show their use in generating the \CONTEXT\ command definitions (\type
+{x-set-11.mkiv}) per January 2016:

+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlrefatt}}

+\startxmlcmd {\cmdbasicsetup{xmlchainattdef}}

+\stopsection
+
+\startsection[title={manipulation}]
+
+You can use \LUA\ code to manipulate the tree and it makes no sense to duplicate
+this in \TEX. In the future we might provide an interface to some of this
+functionality. Keep in mind that manipuating the tree might have side effects as
+we maintain several indices into the tree that also needs to be updated then.
+
+\stopsection
+
+\startsection[title={integration}]
+
+If you write a module that deals with \XML, for instance processing cals tables,
+then you need ways to control specific behaviour. For instance, you might want to
+add a background to the table. Such directives are collected in \XML\ files and
+can be loaded on demand.
+
+\startxmlcmd {\cmdbasicsetup{xmlloaddirectives}}
+    loads \CONTEXT\ directives from \cmdinternal {cd:file} that will get
+    interpreted when processing documents
+\stopxmlcmd
+
+A directives definition file looks as follows:
+
+\starttyping
+<?xml version="1.0" standalone="yes"?>
+
+<directives>
+  <directive attribute='id' value="100"
+    setup="cdx:100"/>
+  <directive attribute='id' value="101"
+    setup="cdx:101"/>
+  <directive attribute='cdx' value="colors" element="cals:table"
+    setup="cdx:cals:table:colors"/>
+  <directive attribute='cdx' value="vertical" element="cals:table"
+    setup="cdx:cals:table:vertical"/>
+  <directive attribute='cdx' value="noframe" element="cals:table"
+    setup="cdx:cals:table:noframe"/>
+  <directive attribute='cdx' value="*" element="cals:table"
+    setup="cdx:cals:table:*"/>
+</directives>
+\stoptyping
+
+Examples of usage can be found in \type {x-cals.mkiv}. The directive is triggered
+by an attribute. Instead of a setup you can specify a setup to be applied before
+and after the node gets flushed.
+
+\startxmlcmd {\cmdbasicsetup{xmldirectives}}
+    apply the setups directive associated with the node
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmldirectivesbefore}}
+    apply the before directives associated with the node
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmldirectivesafter}}
+    apply the after directives associated with the node
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlinstalldirective}}
+    defines a directive that hooks into a handler
+\stopxmlcmd
+
+Normally a directive will be put in the \XML\ file, for instance as:
+
+\starttyping
+<?context-mathml-directive minus reduction yes ?>
+\stoptyping
+
+Here the \type {mathml} is the general class of directives and \type {minus} a
+subclass, in our case a specific element.
+
+\stopsection
+
+\startsection[title={setups}]
+
+The basic building blocks of \XML\ processing are setups. These are just
+collections of macros that are expanded. These setups get one argument passed
+(\type {#1}):
+
+\starttyping
+\startxmlsetups somedoc:somesetup
+    \xmlflush{#1}
+\stopxmlsetups
+\stoptyping
+
+This argument is normally a number that internally refers to a specific node in
+the \XML\ tree. The user should see it as an abstract reference and not depend on
+its numeric property. Just think of it as \quote {the current node}. You can (and
+probably will) call such setups using:
+
+\startxmlcmd {\cmdbasicsetup{xmlsetup}}
+    expands setup \cmdinternal {cd:setup} and pass \cmdinternal {cd:node} as
+    argument
+\stopxmlcmd
+
+However, in most cases the setups are associated to specific elements,
+something that users of \XSLT\ might recognize as templates.
+
+\startxmlcmd {\cmdbasicsetup{xmlsetfunction}}
+    associates function \cmdinternal {cd:luafunction} to the elements in
+    namespace \cmdinternal {cd:name} that match \cmdinternal {cd:lpath}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlsetsetup}}
+    associates setups \cmdinternal {cd:setup} (\TEX\ code) with the matching
+    nodes of \cmdinternal {cd:lpath} or root \cmdinternal {cd:node}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlprependsetup}}
+    pushes \cmdinternal {cd:setup} to the front of global list of setups
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlappendsetup}}
+    adds \cmdinternal {cd:setup} to the global list of setups to be applied
+    (alias: \type{\xmlregistersetup})
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlbeforesetup}}
+    pushes \cmdinternal {cd:setup} into the global list of setups; the
+    last setup is the position
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlaftersetup}}
+    adds \cmdinternal {cd:setup} to the global list of setups; the last setup
+    is the position
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlremovesetup}}
+    removes \cmdinternal {cd:setup} from the global list of setups
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlprependdocumentsetup}}
+    pushes \cmdinternal {cd:setup} to the front of list of setups to be applied
+    to \cmdinternal {cd:name}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlappenddocumentsetup}}
+    adds \cmdinternal {cd:setup} to the list of setups to be applied to
+    \cmdinternal {cd:name} (you can also use the alias: \type
+    {\xmlregisterdocumentsetup})
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlbeforedocumentsetup}}
+    pushes \cmdinternal {cd:setup} into the setups to be applied to \cmdinternal
+    {cd:name}; the last setup is the position
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlafterdocumentsetup}}
+    adds \cmdinternal {cd:setup} to the setups to be applied to \cmdinternal
+    {cd:name}; the last setup is the position
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlremovedocumentsetup}}
+    removes \cmdinternal {cd:setup} from the global list of setups to be applied
+    to \cmdinternal {cd:name}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlresetsetups}}
+    removes all global setups
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlresetdocumentsetups}}
+    removes all setups from the \cmdinternal {cd:name} specific list of setups to
+    be applied
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlflushdocumentsetups}{setup}}
+    applies \cmdinternal {cd:setup} (can be a list) to \cmdinternal {cd:name}
+\stopxmlcmd

+\startxmlcmd {\cmdbasicsetup{xmlregisteredsetups}}
+    applies all global setups to the current document
+\stopxmlcmd

+\stopxmlcmd

+\stopsection
+
+\startsection[title={testing}]
+
+The following test macros all take a \cmdinternal {cd:node} as first argument
+and an \cmdinternal {cd:lpath} as second:
+
+\startxmlcmd {\cmdbasicsetup{xmldoif}}
+    expands to \cmdinternal {cd:true} when \cmdinternal {cd:lpath} matches at
+    node \cmdinternal {cd:node}
+\stopxmlcmd

+\startxmlcmd {\cmdbasicsetup{xmldoifnot}}

+\stopxmlcmd

+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmldoifnottext}}

+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmldoifnotatt}}

+\stopxmlcmd

+\startxmlcmd {\cmdbasicsetup{xmldoifelseatt}}

+\stopsection

+\startsection[title={initialization}]
+
+The general setup command (not to be confused with setups) that deals with the
+\MKIV\ tree handler is \type {\setupxml}. There are currently only a few options.
+
+\cmdfullsetup{setupxml}
+
+When you set \type {default} to \cmdinternal {cd:text} elements with no setup
+assigned will end up as text. When set to \type {hidden} such elements will be
+hidden. You can apply the default yourself using:
+
+\startxmlcmd {\cmdbasicsetup{xmldefaulttotext}}
+    presets the tree with root \cmdinternal {cd:node} to the handlers set up with
+    \type {\setupxml} option \cmdinternal{default}
+\stopxmlcmd
+
+You can set \type {compress} to \type {yes} in which case comment is stripped
+from the tree when the file is read.
+
+\startxmlcmd {\cmdbasicsetup{xmlregisterns}}
+    associates an internal namespace (like \type {mml}) with one given in the
+    document as \URL\ (like mathml)
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlremapname}}
+    changes the namespace and tag of the matching elements
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlremapnamespace}}
+    replaces all references to the given namespace to a new one (applied
+    recursively)
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlchecknamespace}}
+    sets the namespace of the matching elements unless a namespace is already set
+\stopxmlcmd
+
+\stopsection
+
+\startsection[title={helpers}]
+
+Often an attribute will determine the rendering and this may result in many
+tests. Especially when we have multiple attributes that control the output such
+tests can become rather extensive and redundant because one gets $n\times m$ or
+more such tests.
+
+Therefore we have a convenient way to map attributes onto for instance strings or
+commands.
+
+\startxmlcmd {\cmdbasicsetup{xmlmapvalue}}
+    associate a \cmdinternal {cd:text} with a \cmdinternal {cd:category} and
+    \cmdinternal {cd:name} (alias: \type{\xmlmapval})
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlvalue}}
+    expand the value associated with a \cmdinternal {cd:category} and
+    \cmdinternal {cd:name} and if not resolved, expand to the \cmdinternal
+    {cd:text} (alias: \type{\xmlval})
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmldoifelsevalue}}
+    associate a \cmdinternal {cd:text} with a \cmdinternal {cd:category} and
+    \cmdinternal {cd:name}
+\stopxmlcmd
+
+This is used as follows. We define a couple of mappings in the same category:
+
+\starttyping
+\xmlmapvalue{emph}{bold}  {\bf}
+\xmlmapvalue{emph}{italic}{\it}
+\stoptyping
+
+Assuming that we have associated the following setup with the \type {emph}
+element, we can say (with \type {#1} being the current element):
+
+\starttyping
+\startxmlsetups demo:emph
+  \begingroup
+    \xmlvalue{emph}{\xmlatt{#1}{type}}{}
+  \endgroup
+\stopxmlsetups
+\stoptyping
+
+In this case we have no default. The \type {type} attribute triggers the actions,
+as in:
+
+\starttyping
+normal <emph type='bold'>bold</emph> normal
+\stoptyping
+
+This mechanism is not really bound to elements and attributes so you can use this
+mechanism for other purposes as well.

+\startchapter[title={Setting up a converter}]
+
+\startsection[title={from structure to setup}]
+
+We use a very simple document structure for demonstrating how a converter is
+defined. In practice a mapping will be more complex, especially when we have a
+style with complex chapter openings using data coming from all kind of places,
+different styling of sections with the same name, selectively (out of order)
+flushed content, special formatting, etc.
+
+\typefile{manual-demo-1.xml}
+
+Say that this document is stored in the file \type {demo.xml}, then the following
+code can be used as starting point:
+
+\starttyping
+\startxmlsetups xml:demo:base
+  \xmlsetsetup{#1}{document|section|p}{xml:demo:*}
+\stopxmlsetups
+
+\xmlregisterdocumentsetup{demo}{xml:demo:base}
+
+\startxmlsetups xml:demo:document
+  \starttitle[title={Contents}]
+    \placelist[chapter]
+  \stoptitle
+  \xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:demo:section
+  \startchapter[title=\xmlfirst{#1}{/title}]
+    \xmlfirst{#1}{/content}
+  \stopchapter
+\stopxmlsetups
+
+\startxmlsetups xml:demo:p
+  \xmlflush{#1}\endgraf
+\stopxmlsetups
+
+\xmlprocessfile{demo}{demo.xml}{}
+\stoptyping
+
+Watch out! These are not just setups, but specific \XML\ setups which get an
+argument passed (the \type {#1}). If for some reason your \XML\ processing fails,
+it might be that you mistakenly have used a normal setup definition. The argument
+\type {#1} represents the current node (element) and is a unique identifier. For
+instance a \type {<p>..</p>} can have an identifier {demo::5}. So, we can get
+something:
+
+\starttyping
+\xmlflush{demo::5}\endgraf
+\stoptyping
+
+but as well:
+
+\starttyping
+\xmlflush{demo::6}\endgraf
+\stoptyping
+
+Keep in mind that the references tor the actual nodes (elements) are
+abstractions, you never see those \type {<id>::<number>}'s, because we will use
+either the abstract \type {#1} (any node) or an explicit reference like \type
+{demo}. The previous setup when issued will be like:
+
+\starttyping
+\startchapter[title=\xmlfirst{demo::3}{/title}]
+  \xmlfirst{demo::4}{/content}
+\stopchapter
+\stoptyping
+
+Here the \type {title} is used to typeset the chapter title but also for an entry
+in the table of contents. At the moment the title is typeset the \XML\ node gets
+looked up and expanded in real text. However, for the list it gets stored for
+later use. One can argue that this is not needed for \XML, because one can just
+filter all the titles and use page references, but then one also looses the
+control one normally has over such titles. For instance it can be that some
+titles are rendered differently and for that we need to keep track of usage.
+Doing that with transformations or filtering is often more complex than leaving
+that to \TEX. As soon as the list gets typeset, the reference (\type {demo::#3})
+is used for the lookup. This is because by default the title is stored as given.
+So, as long as we make sure the \XML\ source is loaded before the table of
+contents is typeset we're ok. Later we will look into this in more detail, for
+now it's enough to know that in most cases the abstract \type {#1} reference will
+work out ok.
+
+Contrary to the style definitions this interface looks rather low level (with no
+optional arguments) and the main reason for this is that we want processing to be
+fast. So, the basic framework is:
+
+\starttyping
+\startxmlsetups xml:demo:base
+  % associate setups with elements
+\stopxmlsetups
+
+\xmlregisterdocumentsetup{demo}{xml:demo:base}
+
+% define setups for matches
+
+\xmlprocessfile{demo}{demo.xml}{}
+\stoptyping
+
+In this example we mostly just flush the content of an element and in the case of
+a section we flush explicit child elements. The \type {#1} in the example code
+represents the current element. The line:
+
+\starttyping
+\xmlsetsetup{demo}{*}{-}
+\stoptyping
+
+sets the default for each element to \quote {just ignore it}. A \type {+} would
+make the default to always flush the content. This means that at this point we
+only handle:
+
+\starttyping
+<section>
+  <title>Some title</title>
+  <content>
+    <p>a paragraph of text</p>
+  </content>
+</section>
+\stoptyping
+
+In the next section we will deal with the slightly more complex itemize and
+figure placement. At first sight all these setups may look overkill but keep in
+mind that normally the number of elements is rather limited. The complexity is
+often in the style and having access to each snippet of content is actually
+quite handy for that.
+
+\stopsection
+
+\startsection[title={alternative solutions}]
+
+Dealing with an itemize is rather simple (as long as we forget about
+attributes that control the behaviour):
+
+\starttyping
+<itemize>
+  <item>first</item>
+  <item>second</item>
+</itemize>
+\stoptyping
+
+First we need to add \type {itemize} to the setup assignment (unless we've used
+the wildcard \type {*}):
+
+\starttyping
+\xmlsetsetup{demo}{document|section|p|itemize}{xml:demo:*}
+\stoptyping
+
+The setup can look like:
+
+\starttyping
+\startxmlsetups xml:demo:itemize
+  \startitemize
+    \xmlfilter{#1}{/item/command(xml:demo:itemize:item)}
+  \stopitemize
+\stopxmlsetups
+
+\startxmlsetups xml:demo:itemize:item
+  \startitem
+    \xmlflush{#1}
+  \stopitem
+\stopxmlsetups
+\stoptyping
+
+An alternative is to map item directly:
+
+\starttyping
+\xmlsetsetup{demo}{document|section|p|itemize|item}{xml:demo:*}
+\stoptyping
+
+and use:
+
+\starttyping
+\startxmlsetups xml:demo:itemize
+  \startitemize
+    \xmlflush{#1}
+  \stopitemize
+\stopxmlsetups
+
+\startxmlsetups xml:demo:item
+  \startitem
+    \xmlflush{#1}
+  \stopitem
+\stopxmlsetups
+\stoptyping
+
+Sometimes, a more local solution using filters and \type {/command(...)} makes more
+sense, especially when the \type {item} tag is used for other purposes as well.
+
+Explicit flushing with \type {command} is definitely the way to go when you have
+complex products. In one of our projects we compose math school books from many
+thousands of small \XML\ files, and from one source set several products are
+typeset. Within a book sections get done differently, content gets used, ignored
+or interpreted differently depending on the kind of content, so there is a
+constant checking of attributes that drive the rendering. In that a generic setup
+for a title element makes less sense than explicit ones for each case. (We're
+talking of huge amounts of files here, including multiple images on each rendered
+page.)
+
+When using \type {command} you can pass two arguments, the first is the setup for
+the match, the second one for the miss, as in:
+
+\starttyping
+\xmlfilter{#1}{/element/command(xml:true,xml:false)}
+\stoptyping
+
+Back to the example, this leaves us with dealing with the resources, like
+figures:
+
+\starttyping
+<resource type='figure'>
+  <caption>A picture of a cow.</caption>
+  <content><external file="cow.pdf"/></content>
+</resource>
+\stoptyping
+
+Here we can use a more restricted match:
+
+\starttyping
+\xmlsetsetup{demo}{resource[@type='figure']}{xml:demo:figure}
+\xmlsetsetup{demo}{external}{xml:demo:*}
+\stoptyping
+
+and the definitions:
+
+\starttyping
+\startxmlsetups xml:demo:figure
+  \placefigure
+    {\xmlfirst{#1}{/caption}}
+    {\xmlfirst{#1}{/content}}
+\stopxmlsetups
+
+\startxmlsetups xml:demo:external
+  \externalfigure[\xmlatt{#1}{file}]
+\stopxmlsetups
+\stoptyping
+
+At this point it is good to notice that \type {\xmlatt{#1}{file}} is passed as it
+is: a macro call. This means that when a macro like \type {\externalfigure} uses
+the first argument frequently without first storing its value, the lookup is done
+several times. A solution for this is:
+
+\starttyping
+\startxmlsetups xml:demo:external
+  \expanded{\externalfigure[\xmlatt{#1}{file}]}
+\stopxmlsetups
+\stoptyping
+
+Because the lookup is rather fast, normally there is no need to bother about this
+too much because internally \CONTEXT\ already makes sure such expansion happens
+only once.
+
+An alternative definition for placement is the following:
+
+\starttyping
+\xmlsetsetup{demo}{resource}{xml:demo:resource}
+\stoptyping
+
+with:
+
+\starttyping
+\startxmlsetups xml:demo:resource
+  \placefloat
+    [\xmlatt{#1}{type}]
+    {\xmlfirst{#1}{/caption}}
+    {\xmlfirst{#1}{/content}}
+\stopxmlsetups
+\stoptyping
+
+This way you can specify \type {table} as type too. Because you can define your
+own float types, more complex variants are also possible. In that case it makes
+sense to provide some default behaviour too:
+
+\starttyping
+\definefloat[figure-here][figure][default=here]
+\definefloat[figure-left][figure][default=left]
+\definefloat[table-here] [table] [default=here]
+\definefloat[table-left] [table] [default=left]
+
+\startxmlsetups xml:demo:resource
+  \placefloat
+    [\xmlattdef{#1}{type}{figure}-\xmlattdef{#1}{location}{here}]
+    {\xmlfirst{#1}{/caption}}
+    {\xmlfirst{#1}{/content}}
+\stopxmlsetups
+\stoptyping
+
+In this example we support two types and two locations. We default to a figure
+placed (when possible) at the current location.

+\startsection[title=attribute chains]
+
+In \CSS, when an attribute is not present, the parent element is checked, and when
+not found again, the lookup follows the chain till a match is found or the root is
+reached. The following example demonstrates how such a chain lookup works.
+
+\startbuffer[test]
+<something mine="1" test="one" more="alpha">
+  <whatever mine="2" test="two">
+    <whocares mine="3">
+      <!-- this is a test -->
+    </whocares>
+  </whatever>
+</something>
+\stopbuffer
+
+\typebuffer[test]
+
+We apply the following setups to this tree:
+
+\startbuffer[setups]
+\startxmlsetups xml:common
+    [
+        \xmlchainatt{#1}{mine},
+        \xmlchainatt{#1}{test},
+        \xmlchainatt{#1}{more},
+        \xmlchainatt{#1}{none}
+    ]\par
+\stopxmlsetups
+
+\startxmlsetups xml:something
+    something: \xmlsetup{#1}{xml:common}
+    \xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:whatever
+    whatever: \xmlsetup{#1}{xml:common}
+    \xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:whocares
+    whocares: \xmlsetup{#1}{xml:common}
+    \xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:mysetups
+    \xmlsetsetup{#1}{something|whatever|whocares}{xml:*}
+\stopxmlsetups
+
+\xmlregisterdocumentsetup{example-1}{xml:mysetups}
+
+\xmlprocessbuffer{example-1}{test}{}
+\stopbuffer
+
+\typebuffer[setups]
+
+This gives:
+
+\start
+    \getbuffer[setups]
+\stop
+
+\stopsection
+
+\startsection[title=conditional setups]
+
+Say that we have this code:
+
+\starttyping
+\xmldoifelse {#1} {/what[@a='1']} {
+    \xmlfilter {#1} {/what/command('xml:yes')}
+} {
+    \xmlfilter {#1} {/what/command('xml:nop')}
+}
+\stoptyping
+
+Here we first determine if there is a child \type {what} with attribute \type {a}
+set to \type {1}. Depending on the outcome again we check the child nodes for
+being named \type {what}. A faster solution which also takes less code is this:
+
+\starttyping
+\xmlfilter {#1} {/what[@a='1']/command('xml:yes','xml:nop')}
+\stoptyping
+
+\stopsection
+
+\startsection[title=manipulating]
+
+Assume that we have the following \XML\ data:
+
+\startbuffer[test]
+<A>
+  <B>right</B>
+  <B>wrong</B>
+</A>
+\stopbuffer
+
+\typebuffer[test]
+
+But, instead of \type {right} we want to see \type {okay}. We can do that with a
+finalizer:
+
+\startbuffer
+\startluacode
+local rehash = {
+    ["right"] = "okay",
+}
+
+function xml.finalizers.tex.Okayed(collected,what)
+    for i=1,#collected do
+        if what == "all" then
+            local str = xml.text(collected[i])
+            context(rehash[str] or str)
+        else
+            context(str)
+        end
+    end
+end
+\stopluacode
+\stopbuffer
+
+\typebuffer \getbuffer
+
+\startbuffer
+\startxmlsetups xml:A
+	\xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:B
+    (It's \xmlfilter{#1}{./Okayed("all")})
+\stopxmlsetups
+
+\startxmlsetups xml:testsetups
+	\xmlsetsetup{#1}{A|B}{xml:*}
+\stopxmlsetups
+
+\xmlregisterdocumentsetup{example-2}{xml:testsetups}
+\xmlprocessbuffer{example-2}{test}{}
+\stopbuffer
+
+\typebuffer
+
+The result is: \start \inlinebuffer \stop
+
+\stopsection
+
+\startsection[title=cross referencing]
+
+A rather common way to add cross references to \XML\ files is to borrow the
+asymmetrical id's from \HTML. This means that one cannot simply use a value
+of (say) \type {href} to locate an \type {id}. The next example came up on
+the \CONTEXT\ mailing list.
+
+\startbuffer[test]
+<doc>
+    <p>Text
+        <a href="#fn1" class="footnoteref" id="fnref1"><sup>1</sup></a> and
+        <a href="#fn2" class="footnoteref" id="fnref2"><sup>2</sup></a>
+    </p>
+    <div class="footnotes">
+        <hr />
+        <ol>
+            <li id="fn1"><p>A footnote.<a href="#fnref1">↩</a></p></li>
+            <li id="fn2"><p>A second footnote.<a href="#fnref2">↩</a></p></li>
+        </ol>
+    </div>
+</doc>
+\stopbuffer
+
+\typebuffer[test]
+
+We give two variants for dealing with such references. The first solution does
+lookups and depending on the size of the file can be somewhat inefficient.
+
+\startbuffer
+\startxmlsetups xml:doc
+    \blank
+    \xmlflush{#1}
+    \blank
+\stopxmlsetups
+
+\startxmlsetups xml:p
+    \xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:footnote
+    (variant 1)\footnote
+        {\xmlfirst
+            {example-3-1}
+            {div[@class='footnotes']/ol/li[@id='\xmlrefatt{#1}{href}']}}
+\stopxmlsetups
+
+\startxmlsetups xml:initialize
+    \xmlsetsetup{#1}{p|doc}{xml:*}
+    \xmlsetsetup{#1}{a[@class='footnoteref']}{xml:footnote}
+    \xmlsetsetup{#1}{div[@class='footnotes']}{xml:nothing}
+\stopxmlsetups
+
+\xmlresetdocumentsetups{*}
+\xmlregisterdocumentsetup{example-3-1}{xml:initialize}
+
+\xmlprocessbuffer{example-3-1}{test}{}
+\stopbuffer
+
+\typebuffer
+
+This will typeset two footnotes.
+
+\getbuffer
+
+The second variant collects the references so that the time spend on lookups is
+less.
+
+\startbuffer
+\startxmlsetups xml:doc
+    \blank
+    \xmlflush{#1}
+    \blank

+\xmlregisterdocumentsetup{example-3-2}{xml:initialize}

+\getbuffer

+\stopsection

+\startsection[title=mapping values]
+
+One way to process options \type {frame} in the example below is to map the

+The \type {\xmlmapvalue} mechanism is rather efficient and involves a minimum

+\typebuffer
+
+We get:

+\getbuffer
+
+\stopsection
+
+\startsection[title=using \LUA]
+
+In this example we demonstrate how you can delegate rendering to \LUA. We
+will construct a so called extreme table. The input is:
+
+\startbuffer[demo]
+<?xml version="1.0" encoding="utf-8"?>
+
+<a>
+  <b> <c>1</c> <d>Text</d>           </b>

+\stopbuffer

+\typebuffer[demo]

+We color a sequence of the same titles (numbers here) differently. The first

+You can even save a few lines of code:
+
+\starttyping
+\startxmlsetups xml:c
+    \xdef\MyCurrentTitle{\xmltext{#1}{.}}
+    \startxcell
+      [background=color,

+These examples demonstrate that it doesn't hurt to know a little bit of \TEX\
+programming: defining macros and basic comparisons can come in handy. There are
+examples in the test suite, you can peek in the source code, you can consult
+the wiki or you can just ask on the list.
+
+\stopsection
+
+\startsection[title=last match]
+
+For the next example we use the following \XML\ input:
+
+\startbuffer[demo]
+<?xml version "1.0"?>
+<document>
+    <section id="1">
+        <content>
+            <p>first</p>
+            <p>second</p>
+        </content>
+    </section>
+    <section id="2">
+        <content>
+            <p>third</p>
+            <p>fourth</p>
+        </content>
+    </section>
+</document>
+\stopbuffer
+
+\typebuffer[demo]
+
+If you check if some element is present and then act accordingly, you can
+end up with doing the same lookup twice. Although it might sound inefficient,
+in practice it's often not measureable.
+
+\startbuffer
+\startxmlsetups xml:demo:document
+    \type{\xmlall{#1}{/section[@id='2']/content/p}}\par
+    \xmldoif{#1}{/section[@id='2']/content/p} {
+        \xmlall{#1}{/section[@id='2']/content/p}
+    }
+    \type{\xmllastmatch}\par
+    \xmldoif{#1}{/section[@id='2']/content/p} {
+        \xmllastmatch
+    }
+    \type{\xmlall{#1}{last-match::}}\par
+    \xmldoif{#1}{/section[@id='2']/content/p} {
+        \xmlall{#1}{last-match::}
+    }
+    \type{\xmlfilter{#1}{last-match::/command(xml:demo:p)}}\par
+    \xmldoif{#1}{/section[@id='2']/content/p} {
+        \xmlfilter{#1}{last-match::/command(xml:demo:p)}
+    }
+\stopxmlsetups
+
+\startxmlsetups xml:demo:p

+\stopxmlsetups

+\stopxmlsetups
+
+\xmlregisterdocumentsetup{example-6}{xml:demo:base}
+
+\xmlprocessbuffer{example-6}{demo}{}
+\stopbuffer
+
+\typebuffer
+
+In the second check we just flush the last match, so effective we do an \type
+{\xmlall} here. The third and fourth alternatives demonstrate how we can use
+\type {last-match} as axis. The gain is 10\% or more on the lookup but of course
+typesetting often takes relatively more time than the lookup.
+
+\startpacked
+\getbuffer
+\stoppacked
+
+\stopsection
+
+\startsection[title=Finalizers]
+
+The \XML\ parser is also available outside \TEX. Here is an example of its usage.
+We pipe the result to \TEX\ but you can do with \type {t} whatever you like.
+
+\startbuffer
+local x = xml.load("manual-demo-1.xml")
+local t = { }
+
+for c in xml.collected(x,"//*") do
+    if not c.special and not t[c.tg] then
+        t[c.tg] = true
+    end
+end
+
+context.tocontext(table.sortedkeys(t))
+\stopbuffer
+
+% \typebuffer
+
+This returns:
+
+\ctxluabuffer
+
+We can wrap this in a finalizer:
+
+\startbuffer
+xml.finalizers.taglist = function(collected)
+    local t = { }
+    for i=1,#collected do
+        local c = collected[i]
+        if not c.special then
+            local tg = c.tg
+            if tg and not t[tg] then
+                t[tg] = true
+            end
+        end
+    end
+    return table.sortedkeys(t)
+end
+\stopbuffer
+
+\typebuffer
+
+Or in a more extensive one:
+
+\startbuffer
+xml.finalizers.taglist = function(collected,parenttoo)
+    local t = { }
+    for i=1,#collected do
+        local c = collected[i]
+        if not c.special then
+            local tg = c.tg
+            if tg and not t[tg] then
+                t[tg] = true
+            end
+            if parenttoo then
+                local p = c.__p__
+                if p and not p.special then
+                    local tg = p.tg .. ":" .. tg
+                    if tg and not t[tg] then
+                        t[tg] = true
+                    end
+                end
+            end
+        end
+    end
+    return table.sortedkeys(t)
+end
+\stopbuffer
+
+\typebuffer \ctxluabuffer
+
+Usage is as follows:
+
+\startbuffer
+local x = xml.load("manual-demo-1.xml")
+local t = xml.applylpath(x,"//*/taglist()")
+
+context.tocontext(t)
+\stopbuffer
+
+\typebuffer
+
+And indeed we get:
+
+\ctxluabuffer
+
+But we can also say:
+
+\startbuffer
+local x = xml.load("manual-demo-1.xml")
+local t = xml.applylpath(x,"//*/taglist(true)")
+
+context.tocontext(t)
+\stopbuffer
+
+\typebuffer
+
+Now we get:
+
+\ctxluabuffer
+
+\stopsection
+
+\startsection[title=Pure xml]
+
+One might wonder how a \TEX\ macro package would look like when backslashes,
+dollars and percent signs would have no special meaning. In fact, it would be
+rather useless as interpreting commands are triggered by such characters. Any
+formatting or coding system needs such characters. Take \XML: angle brackets and
+ampersands are really special. So, no matter what system we use, we do have to
+deal with the (common) case where these characters need to be seen as they are.
+Normally escaping is the solution.
+
+The \CONTEXT\ interface for \XML\ suffers from this as well. You really don't
+want to know how many tricks are used for dealing with special characters and
+entities: there are several ways these travel through the system and it is
+possible to adapt and cheat. Especially roundtripped data (via tuc file) puts
+some demands on the system because when ts \XML\ can become \TEX\ and vise versa.
+The next example (derived from a mail on the list) demonstrates this:
+
+\starttyping
+\startbuffer[demo]

+    <pre><code>\ConTeXt\ is great</code></pre>
+

+\startchapter[title={Expressions and filters}]
+
+\startsection[title={path expressions}]
+
+In the previous chapters we used \cmdinternal {cd:lpath} expressions, which are a variant
+on \type {xpath} expressions as in \XSLT\ but in this case more geared towards
+usage in \TEX. This mechanisms will be extended when demands are there.
+
+A path is a sequence of matches. A simple path expression is:
+
+\starttyping
+a/b/c/d
+\stoptyping
+
+Here each \type {/} goes one level deeper. We can go backwards in a lookup with
+\type {..}:
+
+\starttyping
+a/b/../d
+\stoptyping
+
+We can also combine lookups, as in:
+
+\starttyping
+a/(b|c)/d
+\stoptyping
+
+A negated lookup is preceded by a \type {!}:
+
+\starttyping
+a/(b|c)/!d
+\stoptyping
+
+A wildcard is specified with a \type {*}:
+
+\starttyping
+a/(b|c)/!d/e/*/f
+\stoptyping
+
+In addition to these tag based lookups we can use attributes:
+
+\starttyping
+a/(b|c)/!d/e/*/f[@type=whatever]
+\stoptyping
+
+An \type {@} as first character means that we are dealing with an attribute.
+Within the square brackets there can be boolean expressions:
+
+\starttyping
+a/(b|c)/!d/e/*/f[@type=whatever and @id>100]
+\stoptyping
+
+You can use functions as in:
+
+\starttyping
+a/(b|c)/!d/e/*/f[something(text()) == "oeps"]
+\stoptyping
+
+There are a couple of predefined functions:
+
+\starttabulate[|l|l|p|]
+\NC \type{rootposition} \type{order} \NC number \NC the index of the matched root element (kind of special) \NC \NR
+\NC \type{position}                  \NC number \NC the current index of the matched element in the match list \NC \NR
+\NC \type{match}                     \NC number \NC the current index of the matched element sub list with the same parent \NC \NR
+\NC \type{first}                     \NC number \NC \NC \NR
+\NC \type{last}                      \NC number \NC \NC \NR
+\NC \type{index}                     \NC number \NC the current index of the matched element in its parent list \NC \NR
+\NC \type{firstindex}                \NC number \NC \NC \NR
+\NC \type{lastindex}                 \NC number \NC \NC \NR
+\NC \type{element}                   \NC number \NC the element's index \NC \NR
+\NC \type{firstelement}              \NC number \NC \NC \NR
+\NC \type{lastelement}               \NC number \NC \NC \NR
+\NC \type{text}                      \NC string \NC the textual representation of the matched element \NC \NR
+\NC \type{content}                   \NC table  \NC the node of the matched element \NC \NR
+\NC \type{name}                      \NC string \NC the full name of the matched element: namespace and tag \NC \NR
+\NC \type{namespace} \type{ns}       \NC string \NC the namespace of the matched element \NC \NR
+\NC \type{tag}                       \NC string \NC the tag of the matched element \NC \NR
+\NC \type{attribute}                 \NC string \NC the value of the attribute with the given name of the matched element \NC \NR
+\stoptabulate
+
+There are fundamental differences between \type {position}, \type {match} and
+\type {index}. Each step results in a new list of matches. The \type {position}
+is the index in this new (possibly intermediate) list. The \type {match} is also
+an index in this list but related to the specific match of element names. The
+\type {index} refers to the location in the parent element.
+
+Say that we have:
+
+\starttyping
+<collection>
+  <resources>
+    <manual>
+      <screen>.1.</screen>
+      <paper>.1.</paper>
+    </manual>
+    <manual>
+      <paper>.2.</paper>
+      <screen>.2.</screen>
+    </manual>
+  <resources>
+  <resources>
+    <manual>
+      <screen>.3.</screen>
+      <paper>.3.</paper>
+    </manual>
+  <resources>
+<collection>
+\stoptyping
+
+The following then applies:
+
+\starttabulate[|l|l|]
+\NC \type {collection/resources/manual[position()==1]/paper} \NC \type{.1.} \NC \NR
+\NC \type {collection/resources/manual[match()==1]/paper}    \NC \type{.1.} \type{.3.} \NC \NR
+\NC \type {collection/resources/manual/paper[index()==1]}    \NC \type{.2.} \NC \NR
+\stoptabulate
+
+In most cases the \type {position} test is more restrictive than the \type
+{match} test.
+
+You can pass your own functions too. Such functions are defined in the \type
+{xml.expressions} namespace. We have defined a few shortcuts:
+
+\starttabulate[|l|l|]
+\NC \type {find(str,pattern)} \NC \type{string.find}      \NC \NR
+\NC \type {contains(str)}     \NC \type{string.find}      \NC \NR
+\NC \type {oneof(str,...)}    \NC is \type{str} in list   \NC \NR
+\NC \type {upper(str)}        \NC \type{characters.upper} \NC \NR
+\NC \type {lower(str)}        \NC \type{characters.lower} \NC \NR
+\NC \type {number(str)}       \NC \type{tonumber}         \NC \NR
+\NC \type {boolean(str)}      \NC \type{toboolean}        \NC \NR
+\NC \type {idstring(str)}     \NC removes leading hash    \NC \NR
+\NC \type {name(index)}       \NC full tag name           \NC \NR
+\NC \type {tag(index)}        \NC tag name                \NC \NR
+\NC \type {namespace(index)}  \NC namespace of tag        \NC \NR
+\NC \type {text(index)}       \NC content                 \NC \NR
+\NC \type {error(str)}        \NC quit and show error     \NC \NR
+\NC \type {quit()}            \NC quit                    \NC \NR
+\NC \type {print()}           \NC print message           \NC \NR
+\NC \type {count(pattern)}    \NC number of matches       \NC \NR
+\NC \type {child(pattern)}    \NC take child that matches \NC \NR
+\stoptabulate
+
+
+You can also use normal \LUA\ functions as long as you make sure that you pass
+the right arguments. There are a few predefined variables available inside such
+functions.
+
+\starttabulate[|Tl|l|p|]
+\NC \type{list}  \NC table   \NC the list of matches \NC \NR
+\NC \type{l}     \NC number  \NC the current index in the list of matches \NC \NR
+\NC \type{ll}    \NC element \NC the current element that matched \NC \NR
+\NC \type{order} \NC number  \NC the position of the root of the path \NC \NR
+\stoptabulate
+
+The given expression between \type {[]} is converted to a \LUA\ expression so you
+can use the usual operators:
+
+\starttyping
+== ~= <= >= < > not and or ()
+\stoptyping
+
+In addition, \type {=} equals \type {==} and \type {!=} is the same as \type
+{~=}. If you mess up the expression, you quite likely get a \LUA\ error message.

+The \CSS\ approach to filtering is a bit different from the path based one and is
+supported too. In fact, you can combine both methods. Depending on what you
+select, the \CSS\ one can be a little bit faster too. It has the advantage that
+one can select more in one go but at the same time looks a bit less attractive.
+This method was added just to show that it can be done but might be useful too. A
+selector is given between curly braces (after all \CSS\ uses them and they have no

+\stoptabulate
+
+The next pages show some examples. For that we use the demo file:
+
+\typebuffer[selector-001]
+
+The class and id selectors often only make sense in \HTML\ like documents but they
+are supported nevertheless. They are after all just shortcuts for filtering by
+attribute. The class filtering is special in the sense that it checks for a class
+in a list of classes given in an attribute.
+
+\showCSSdemo{selector-001}{{.one}}
+\showCSSdemo{selector-001}{{.one, .two}}
+\showCSSdemo{selector-001}{{.one, .two, \letterhash first}}
+
+Attributes can be filtered by presence, value, partial value and such. Quotes are
+optional but we advice to use them.
+
+\showCSSdemo{selector-001}{{[foo], [bar=foo]}}
+\showCSSdemo{selector-001}{{[bar\lettertilde=foo]}}
+\showCSSdemo{selector-001}{{[bar\letterhat="foo"]}}
+\showCSSdemo{selector-001}{{[whatever\lettertilde="five"]}}
+
+You can of course combine the methods as in:
+
+\showCSSdemo{selector-001}{{g f .one, g f .three}}
+\showCSSdemo{selector-001}{{g > f .one, g > f .three}}
+\showCSSdemo{selector-001}{{d + e}}
+\showCSSdemo{selector-001}{{d ~ e}}
+\showCSSdemo{selector-001}{{d ~ e, g f .one, g f .three}}
+
+You can also negate the result by using \type {:not} on a simple expression:
+
+\showCSSdemo{selector-001}{{:not([whatever\lettertilde="five"])}}
+\showCSSdemo{selector-001}{{:not(d)}}
+
+The child and match selectors are also supported:
+
+\showCSSdemo{selector-001}{{a:nth-child(3)}}
+\showCSSdemo{selector-001}{{a:nth-last-child(3)}}
+\showCSSdemo{selector-001}{{g:nth-of-type(3)}}
+\showCSSdemo{selector-001}{{g:nth-last-of-type(3)}}
+\showCSSdemo{selector-001}{{a:first-child}}
+\showCSSdemo{selector-001}{{a:last-child}}
+\showCSSdemo{selector-001}{{e:first-of-type}}
+\showCSSdemo{selector-001}{{gg d:only-of-type}}
+
+Instead of numbers you can also give the \type {an} and \type {an+b} formulas
+as well as the \type {odd} and \type {even} keywords:
+
+\showCSSdemo{selector-001}{{a:nth-child(even)}}
+\showCSSdemo{selector-001}{{a:nth-child(odd)}}
+\showCSSdemo{selector-001}{{a:nth-child(3n+1)}}
+\showCSSdemo{selector-001}{{a:nth-child(2n+3)}}
+
+There are a few special cases:
+
+\showCSSdemo{selector-001}{{g:empty}}
+\showCSSdemo{selector-001}{{g:root}}
+\showCSSdemo{selector-001}{{*}}
+
+Combining the \CSS\ methods with the regular ones is possible:
+
+\showCSSdemo{selector-001}{{g gg f .one}}
+\showCSSdemo{selector-001}{g/gg/f[@class='one']}
+\showCSSdemo{selector-001}{g/{gg f .one}}
+
+\startbuffer[selector-002]
+<?xml version="1.0" ?>
+
+<document>
+    <title class="one"  >title 1</title>
+    <title class="two"  >title 2</title>
+    <title class="one"  >title 3</title>
+    <title class="three">title 4</title>
+</document>
+\stopbuffer
+
+The next examples we use this file:
+
+\typebuffer[selector-002]
+
+\xmlloadbuffer{selector-002}{selector-002}
+
+When we filter from this (not too well structured) tree we can use both
+methods to achieve the same:
+
+\showCSSdemo{selector-002}{{document title .one, document title .three}}
+
+\showCSSdemo{selector-002}{/document/title[(@class='one') or (@class='three')]}
+
+However, imagine this file:
+
+\startbuffer[selector-003]
+<?xml version="1.0" ?>
+
+<document>
+    <title    class="one">title 1</title>
+    <subtitle class="sub">title 1.1</subtitle>
+    <title    class="two">title 2</title>
+    <subtitle class="sub">title 2.1</subtitle>
+    <title    class="one">title 3</title>
+    <subtitle class="sub">title 3.1</subtitle>
+    <title    class="two">title 4</title>
+    <subtitle class="sub">title 4.1</subtitle>
+</document>
+\stopbuffer
+
+\typebuffer[selector-003]
+
+\xmlloadbuffer{selector-003}{selector-003}
+
+The next filter in easier with the \CSS\ selector methods because these accumulate
+independent (simple) expressions:
+
+\showCSSdemo{selector-003}{{document title .one + subtitle, document title .two + subtitle}}
+
+Watch how we get an output in the document order. Because we render a sequential document
+a combined filter will trigger a sorting pass.
+
+\stopsection
+
+\startsection[title={functions as filters}]
+
+At the \LUA\ end a whole \cmdinternal {cd:lpath} expression results in a (set of) node(s)
+with its environment, but that is hardly usable in \TEX. Think of code like:
+
+\starttyping
+for e in xml.collected(xml.load('text.xml'),"title") do
+  -- e = the element that matched
+end
+\stoptyping
+
+The older variant is still supported but you can best use the previous variant.
+
+\starttyping
+for r, d, k in xml.elements(xml.load('text.xml'),"title") do
+  -- r = root of the title element
+  -- d = data table
+  -- k = index in data table
+end
+\stoptyping
+
+Here \type {d[k]} points to the \type {title} element and in this case all titles
+in the tree pass by. In practice this kind of code is encapsulated in function
+calls, like those returning elements one by one, or returning the first or last
+match. The result is then fed back into \TEX, possibly after being altered by an
+associated setup. We've seen the wrappers to such functions already in a previous
+chapter.
+
+In addition to the previously discussed expressions, one can add so called
+filters to the expression, for instance:
+
+\starttyping
+a/(b|c)/!d/e/text()
+\stoptyping
+
+In a filter, the last part of the \cmdinternal {cd:lpath} expression is a
+function call. The previous example returns the text of each element \type {e}
+that results from matching the expression. When running \TEX\ the following
+functions are available. Some are also available when using pure \LUA. In \TEX\
+you can often use one of the macros like \type {\xmlfirst} instead of a \type
+{\xmlfilter} with finalizer \type {first()}. The filter can be somewhat faster
+but that is hardly noticeable.

+\stoptabulate
+
+The extra arguments of the concatinators are: \type {separator} (string), \type
+{lastseparator} (string) and \type {textonly} (a boolean).
+
+These filters are in fact \LUA\ functions which means that if needed more of them
+can be added. Indeed this happens in some of the \XML\ related \MKIV\ modules,
+for instance in the \MATHML\ processor.
+
+\stopsection
+
+\startsection[title={example}]
+
+The number of commands is rather large and if you want to avoid them this is
+often possible. Take for instance:
+
+\starttyping
+\xmlall{#1}{/a/b[position()>3]}
+\stoptyping
+
+Alternatively you can use:
+
+\starttyping
+\xmlfilter{#1}{/a/b[position()>3]/all()}
+\stoptyping
+
+and actually this is also faster as internally it avoids a function call. Of
+course in practice this is hardly measurable.
+
+In previous examples we've already seen quite some expressions, and it might be
+good to point out that the syntax is modelled after \XSLT\ but is not quite the
+same. The reason is that we started with a rather minimal system and have already
+styles in use that depend on compatibility.
+
+\starttyping
+namespace:// axis node(set) [expr 1]..[expr n] / ... / filter
+\stoptyping
+
+When we are inside a \CONTEXT\ run, the namespace is \type {tex}. Hoewever, if
+you want not to print back to \TEX\ you need to be more explicit. Say that we
+typeset examns and have a (not that logical) structure like:
+
+\starttyping
+<question>
+  <text>...</text>
+  <answer>
+    <item>one</item>
+    <item>two</item>
+    <item>three</item>
+  </answer>
+  <alternative>
+    <condition>true</condition>
+    <score>1</score>
+  </alternative>
+  <alternative>
+    <condition>false</condition>
+    <score>0</score>
+  </alternative>
+  <alternative>
+    <condition>true</condition>
+    <score>2</score>
+  </alternative>
+</question>
+\stoptyping
+
+Say that we typeset the questions with:
+
+\starttyping
+\startxmlsetups question
+  \blank
+  score: \xmlfunction{#1}{totalscore}
+  \blank
+  \xmlfirst{#1}{text}
+  \startitemize
+      \xmlfilter{#1}{/answer/item/command(answer:item)}
+  \stopitemize
+  \endgraf
+  \blank
+\stopxmlsetups
+\stoptyping
+
+Each item in the answer results in a call to:
+
+\starttyping
+\startxmlsetups answer:item
+  \startitem
+    \xmlflush{#1}
+    \endgraf
+    \xmlfilter{#1}{../../alternative[position()=rootposition()]/
+      condition/command(answer:condition)}
+  \stopitem
+\stopxmlsetups
+\stoptyping
+
+\starttyping
+\startxmlsetups answer:condition
+  \endgraf
+  condition: \xmlflush{#1}
+  \endgraf
+\stopxmlsetups
+\stoptyping
+
+Now, there are two rather special filters here. The first one involves
+calculating the total score. As we look forward we use a function to deal with
+this.
+
+\starttyping
+\startluacode
+function xml.functions.totalscore(root)
+  local score = 0
+  for e in xml.collected(root,"/alternative") do
+    score = score + xml.filter(e,"xml:///score/number()") or 0
+  end
+  tex.write(score)
+end
+\stopluacode
+\stoptyping
+
+Watch how we use the namespace to keep the results at the \LUA\ end.
+
+The second special trick shown here is to limit a match using the current
+position of the root (\type {#}) match.
+
+As you can see, a path expression can be more than just filtering a few nodes. At
+the end of this manual you will find a bunch of examples.
+
+\stopsection
+
+\startsection[title={tables}]
+
+If you want to know how the internal \XML\ tables look you can print such a
+table:
+
+\starttyping
+print(table.serialize(e))
+\stoptyping
+
+This produces for instance:
+
+% s = xml.convert("<document><demo label='whatever'>some text</demo></document>")
+% print(table.serialize(xml.filter(s,"demo")[1]))
+
+\starttyping
+t={
+ ["at"]={
+  ["label"]="whatever",
+ },
+ ["dt"]={ "some text" },
+ ["ns"]="",
+ ["rn"]="",
+ ["tg"]="demo",
+}
+\stoptyping
+
+The \type {rn} entry is the renamed namespace (when renaming is applied). If you
+see tags like \type {@pi@} this means that we don't have an element, but (in this
+case) a processing instruction.
+
+\starttabulate[|l|p|]
+\NC \type {@rt@} \NC the root element \NC \NR
+\NC \type {@dd@} \NC document definition \NC \NR
+\NC \type {@cm@} \NC comment, like \type {<!-- whatever -->} \NC \NR
+\NC \type {@cd@} \NC so called \type {CDATA} \NC \NR
+\NC \type {@pi@} \NC processing instruction, like \type {<?whatever we want ?>} \NC \NR
+\stoptabulate
+
+There are many ways to deal with the content, but in the perspective of \TEX\
+only a few matter.
+
+\starttabulate[|l|p|]
+\NC \type {xml.sprint(e)} \NC print the content to \TEX\ and apply setups if needed \NC \NR
+\NC \type {xml.tprint(e)} \NC print the content to \TEX\ (serialize elements verbose) \NC \NR
+\NC \type {xml.cprint(e)} \NC print the content to \TEX\ (used for special content) \NC \NR
+\stoptabulate
+
+Keep in mind that anything low level that you uncover is not part of the official
+interface unless mentioned in this manual.

+\startsection[title={\TEX\ versus \LUA}]
+
+It will not come as a surprise that we can access \XML\ files from \TEX\ as well
+as from \LUA. In fact there are two methods to deal with \XML\ in \LUA. First
+there are the low level \XML\ functions in the \type {xml} namespace. On top of
+those functions there is a set of functions in the \type {lxml} namespace that
+deals with \XML\ in a more \TEX ie way. Most of these have similar commands at
+the \TEX\ end.
+
+\startbuffer
+\startxmlsetups first:demo:one
+  \xmlfilter {#1} {artist/name[text()='Randy Newman']/..
+    /albums/album[position()=3]/command(first:demo:two)}
+\stopxmlsetups
+
+\startxmlsetups first:demo:two
+  \blank \start \tt
+    \xmldisplayverbatim{#1}
+  \stop \blank
+\stopxmlsetups
+
+\xmlprocessfile{demo}{music-collection.xml}{first:demo:one}
+\stopbuffer
+
+\typebuffer
+
+This gives the following snippet of verbatim \XML\ code. The indentation is
+conform the indentation in the whole \XML\ file. \footnote {The (probably
+outdated) \XML\ file contains the collection stores on my slimserver instance.
+You can use the \type {mtxrun --script flac} to generate such files.}
+
+\doifmodeelse {atpragma} {
+    \getbuffer
+} {
+    \typefile{xml-mkiv-01.xml}
+}
+
+An alternative written in \LUA\ looks as follows:
+
+\startbuffer
+\blank \start \tt \startluacode
+  local m = lxml.load("mine","music-collection.xml") -- m == lxml.id("mine")
+  local p = "artist/name[text()='Randy Newman']/../albums/album[position()=4]"
+  local l = lxml.filter(m,p) -- returns a list (with one entry)
+  lxml.displayverbatim(l[1])
+\stopluacode \stop \blank
+\stopbuffer
+
+\typebuffer
+
+This produces:
+
+\doifmodeelse {atpragma} {
+    \getbuffer
+} {
+    \typefile{xml-mkiv-02.xml}
+}
+
+You can use both methods mixed but in practice we will use the \TEX\ commands in
+regular styles and the mixture in modules, for instance in those dealing with
+\MATHML\ and cals tables. For complex matters you can write your own finalizers
+(the last action to be taken in a match) in \LUA\ and use them at the \TEX\ end.
+
+\stopsection
+
+\startsection[title={a few details}]
+
+In \CONTEXT\ setups are a rather common variant on macros (\TEX\ commands) but
+with their own namespace. An example of a setup is:
+
+\starttyping
+\startsetup doc:print
+  \setuppapersize[A4][A4]
+\stopsetup
+
+\startsetup doc:screen
+  \setuppapersize[S6][S4]
+\stopsetup
+\stoptyping
+
+Given the previous definitions, later on we can say something like:
+
+\starttyping
+\doifmodeelse {paper} {
+  \setup[doc:print]
+} {
+  \setup[doc:screen]
+}
+\stoptyping
+
+Another example is:
+
+\starttyping
+\startsetup[doc:header]
+  \marking[chapter]
+  \space
+  --
+  \space
+  \pagenumber
+\stopsetup
+\stoptyping
+
+in combination with:
+
+\starttyping
+\setupheadertexts[\setup{doc:header}]
+\stoptyping
+
+Here the advantage is that instead of ending up with an unreadable header
+definitions, we use a nicely formatted setup. An important property of setups and
+the reason why they were introduced long ago is that spaces and newlines are
+ignored in the definition. This means that we don't have to worry about so called
+spurious spaces but it also means that when we do want a space, we have to use
+the \type {\space} command.
+
+The only difference between setups and \XML\ setups is that the following ones
+get an argument (\type {#1}) that reflects the current node in the \XML\ tree.
+
+\stopsection
+
+\startsection[title={CDATA}]
+
+What to do with \type {CDATA}? There are a few methods at tle \LUA\ end for
+dealing with it but here we just mention how you can influence the rendering.
+There are four macros that play a role here:
+
+\starttyping
+\unexpanded\def\xmlcdataobeyedline {\obeyedline}
+\unexpanded\def\xmlcdataobeyedspace{\strut\obeyedspace}
+\unexpanded\def\xmlcdatabefore     {\begingroup\tt}
+\unexpanded\def\xmlcdataafter      {\endgroup}
+\stoptyping
+
+Technically you can overload them but beware of side effects. Normally you won't
+see much \type {CDATA} and whenever we do, it involves special data that needs
+very special treatment anyway.
+
+\stopsection
+
+\startsection[title={Entities}]
+
+As usual with any way of encoding documents you need escapes in order to encode
+the characters that are used in tagging the content, embedding comments, escaping
+special characters in strings (in programming languages), etc. In \XML\ this
+means that in order characters like \type {<} you need an escape like \type
+{&lt;} and in order then to encode an \type {&} you need \type {&amp;}.
+
+In a typesetting workflow using a programming language like \TEX, another problem
+shows up. There we have different special characters, like \type {$ $} for triggering
+math, but also the backslash, braces etc. Even one such special character is already
+enough to have yet another escaping mechanism at work.
+
+Ideally a user should not worry about these issues but it helps figuring out issues
+when you know what happens under the hood. Also it is good to know that in the
+code there are several ways to deal with these issues. Take the following document:
+
+\starttyping
+<text>
+    Here we have a bit of a &lt;&mess&gt;:
+
+    # &#35;
+    % &#37;
+    \ &#92;
+    { &#123;
+    | &#124;
+    } &#125;
+    ~ &#126;
+</text>
+\stoptyping
+
+When the file is read the \type {&lt;} entity will be replaced by \type {<} and
+the \type {&gt;} by \type {>}. The numeric entities will be replaced by the
+characters they refer to. The \type {&mess} is kind of special. We do preload
+a huge list of more or less standardized entities but \type {mess} is not in
+there. However, it is possible to have it defined in the document preamble, like:
+
+\starttyping
+<!DOCTYPE dummy SYSTEM "dummy.dtd" [
+    <!ENTITY mess "what a mess" >
+]>
+\stoptyping
+
+or even this:
+
+\starttyping
+<!DOCTYPE dummy SYSTEM "dummy.dtd" [
+    <!ENTITY mess "<p>what a mess</p>" >

+
+You can also define it in your document style using one of:
+
+\startxmlcmd {\cmdbasicsetup{xmlsetentity}}
+    replaces entity with name \cmdinternal {cd:name} by \cmdinternal {cd:text}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmltexentity}}
+    replaces entity with name \cmdinternal {cd:name} by \cmdinternal {cd:text}
+    typeset under a \TEX\ regime
+\stopxmlcmd
+
+Such a definition will always have a higher priority than the one defined
+in the document. Anyway, when the document is read in all entities are
+resolved and those that need a special treatment because they map to some
+text are stored in such a way that we can roundtrip them. As a consequence,
+as soon as the content gets pushed into \TEX, we need not only to intercept
+special characters but also have to make sure that the following works:
+
+\starttyping
+\xmltexentity {tex} {\TEX}
+\stoptyping
+
+Here the backslash starts a control sequence while in regular content a
+backslash is just that: a backslash.
+
+Special characters are really special when we have to move text around
+in a \TEX\ ecosystem.
+
+\starttyping
+<text>
+    <title>About #3</title>
+</text>
+\stoptyping
+
+If we map and define title as follows:
+
+\starttyping
+\startxmlsetup xml:title
+    \title{\xmlflush{#1}}
+\stopxmlsetup
+\stoptyping
+
+normally something \type {\xmlflush {id::123}} will be written to the
+auxiliary file and in most cases that is quite okay, but if we have this:
+
+\starttyping
+\setuphead[title][expansion=yes]
+\stoptyping
+
+then we don't want the \type {#} to end up as hash because later on \TEX\
+can get very confused about it because it sees some argument then in a
+probably unexpected way. This is solved by escaping the hash like this:
+
+\starttyping
+About \Ux{23}3
+\stoptyping
+
+The \type {\Ux} command will convert its hexadecimal argument into a
+character. Of course one then needs to typeset such a text under a \TEX\
+character regime but that is normally the case anyway.

+\startchapter[title={Introduction}]
+
+This manual presents the \MKIV\ way of dealing with \XML. Although the
+traditional \MKII\ streaming parser has a charming simplicity in its control, for
+complex documents the tree based \MKIV\ method is more convenient. It is for this
+reason that the old method has been removed from \MKIV. If you are familiar with
+\XML\ processing in \MKII, then you will have noticed that the \MKII\ commands
+have \type {XML} in their name. The \MKIV\ commands have a lowercase \type {xml}
+in their names. That way there is no danger for confusion or a mixup.
+
+You may wonder why we do these manipulations in \TEX\ and not use \XSLT\ (or
+other transformation methods) instead. The advantage of an integrated approach is
+that it simplifies usage. Think of not only processing the document, but also
+using \XML\ for managing resources in the same run. An \XSLT\ approach is just as
+verbose (after all, you still need to produce \TEX\ code) and probably less
+readable. In the case of \MKIV\ the integrated approach is also faster and gives
+us the option to manipulate content at runtime using \LUA. It has the additional
+advantage that to some extend we can handle a mix of \TEX\ and \XML\ because we
+know when we're doing one or the other.
+
+This manual is dedicated to Taco Hoekwater, one of the first \CONTEXT\ users, and
+also the first to use it for processing \XML. Who could have thought at that time
+that we would have a more convenient way of dealing with those angle brackets.
+The second version for this manual is dedicated to Thomas Schmitz, a power user
+who occasionally became victim of the evolving mechanisms.

+\startchapter[title={Lookups using lpaths}]
+
+\startsection[title={introduction}]
+
+There is not that much system in the following examples. They resulted from tests
+with different documents. The current implementation evolved out of the
+experimental code. For instance, I decided to add the multiple expressions in row
+handling after a few email exchanges with Jean|-|Michel Huffen.
+
+One of the main differences between the way \XSLT\ resolves a path and our way is
+the anchor. Take:
+
+\starttyping
+/something
+something
+\stoptyping
+
+The first one anchors in the current (!) element so it will only consider direct
+children. The second one does a deep lookup and looks at the descendants as well.
+Furthermore we have a few extra shortcuts like \type {**} in \type {a/**/b} which
+represents all descendants.
+
+The expressions (between square brackets) has to be valid \LUA\ and some
+preprocessing is done to resolve the built in functions. So, you might use code
+like:
+
+\starttyping
+my_lpeg_expression:match(text()) == "whatever"
+\stoptyping
+
+given that \type {my_lpeg_expression} is known. In the examples below we use the
+visualizer to show the steps. Some are shown more than once as part of a set.

+
+There is also \type {last-match::} that starts with the last found set of nodes.
+This can save some run time when you do lots of tests combined with a same check
+afterwards. There is however one pitfall: you never know what is done with that
+last match in the setup that gets called nested. Take the following example:
+
+\starttyping
+\startbuffer[test]
+<something>
+    <crap> <crapa> <crapb> <crapc> <crapd>
+        <crape>
+            done 1
+        </crape>
+    </crapd>  </crapc> </crapb>  </crapa>
+    <crap> <crapa> <crapb> <crapc> <crapd>
+        <crape>
+            done 2
+        </crape>
+    </crapd>  </crapc> </crapb>  </crapa>
+    <crap> <crapa> <crapb> <crapc> <crapd>
+        <crape>
+            done 3
+        </crape>
+    </crapd>  </crapc> </crapb>  </crapa>
+</something>
+\stopbuffer
+\stoptyping
+
+One way to filter the content is this:
+
+\starttyping
+\xmldoif {#1} {/crap/crapa/crapb/crapc/crapd/crape} {
+    some action
+}
+\stoptyping
+
+It is not unlikely that you will do something like this:
+
+\starttyping
+\xmlfirst {#1} {/crap/crapa/crapb/crapc/crapd/crape} {
+    \xmlfirst{#1}{/crap/crapa/crapb/crapc/crapd/crape}
+}
+\stoptyping
+
+This means that the path is resolved twice but that can be avoided as
+follows:
+
+\starttyping
+\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
+    \xmlfirst{#1}{last-match::}
+}
+\stoptyping
+
+But the next is now guaranteed to work:
+
+\starttyping
+\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
+    \xmlfirst{#1}{last-match::}
+    \xmllast{#1}{last-match::}
+}
+\stoptyping
+
+Because the first one can have done some lookup the last match can be replaced
+and the second call will give unexpected results. You can overcome this with:
+
+\starttyping
+\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
+    \xmlpushmatch
+    \xmlfirst{#1}{last-match::}
+    \xmlpopmatch
+}
+\stoptyping
+
+Does it pay off? Here are some timings of a 10.000 times text and lookup
+like the previous (on a decent January 2016 laptop):
+
+\starttabulate[|r|l|]
+\NC 0.239 \NC \type {\xmldoif {...} {...}}                                     \NC \NR
+\NC 0.292 \NC \type {\xmlfirst {...} {...}}                                    \NC \NR
+\NC 0.538 \NC \type {\xmldoif {...} {...} + \xmlfirst {...} {...}}             \NC \NR
+\NC 0.338 \NC \type {\xmldoif {...} {...} + \xmlfirst {...} {last-match::}}    \NC \NR
+\NC 0.349 \NC \type {+ \xmldoif {...} {...} + \xmlfirst {...} {last-match::}-} \NC \NR
+\stoptabulate
+
+So, pushing and popping (the last row) is a bit slower than not doing that but it
+is still much faster than not using \type {last-match::} at all. As a shortcut
+you can use \type {=}, as in:
+
+\starttyping
+\xmlfirst{#1}{=}
+\stoptyping
+
+You can even do this:
+
+\starttyping
+\xmlall{#1}{last-match::/text()}
+\stoptyping
+
+or
+
+\starttyping
+\xmlall{#1}{=/text()}

+
+\startsection[title={tracing}]
+
+It can be hard to debug code as much happens kind of behind the screens.
+Therefore we have a couple of tracing options. Of course you can typeset some
+status information, using for instance:
+
+\startxmlcmd {\cmdbasicsetup{xmlshow}}
+    typeset the tree given by \cmdinternal {cd:node}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlinfo}}
+    typeset the name in the element given by \cmdinternal {cd:node}
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlpath}}
+    returns the complete path (including namespace prefix and index) of the
+    given \cmdinternal {cd:node}
+\stopxmlcmd
+
+\startbuffer[demo]
+<?xml version "1.0"?>
+<document>
+    <section>
+        <content>
+            <p>first</p>
+            <p><b>second</b></p>
+        </content>
+    </section>
+    <section>
+        <content>
+            <p><b>third</b></p>
+            <p>fourth</p>
+        </content>
+    </section>
+</document>
+\stopbuffer
+
+Say that we have the following \XML:
+
+\typebuffer[demo]
+
+and the next definitions:
+
+\startbuffer
+\startxmlsetups xml:demo:base
+    \xmlsetsetup{#1}{p|b}{xml:demo:*}
+\stopxmlsetups
+
+\startxmlsetups xml:demo:p
+    \xmlflush{#1}
+    \par
+\stopxmlsetups
+
+\startxmlsetups xml:demo:b
+    \par
+    \xmlpath{#1} : \xmlflush{#1}
+    \par
+\stopxmlsetups
+
+\xmlregisterdocumentsetup{example-10}{xml:demo:base}
+
+\xmlprocessbuffer{example-10}{demo}{}
+\stopbuffer
+
+\typebuffer
+
+This will give us:
+
+\blank \startpacked \getbuffer \stoppacked \blank
+
+If you use \type {\xmlshow} you will get a complete subtree which can
+be handy for tracing but can also lead to large documents.
+
+We also have a bunch of trackers that can be enabled, like:
+
+\starttyping
+\enabletrackers[xml.show,xml.parse]
+\stoptyping
+
+The full list (currently) is:
+
+\starttabulate[|lT|p|]
+\NC xml.entities  \NC show what entities are seen and replaced \NC \NR
+\NC xml.path      \NC show the result of parsing an lpath expression \NC \NR
+\NC xml.parse     \NC show stepwise resolving of expressions \NC \NR
+\NC xml.profile   \NC report all parsed lpath expressions (in the log) \NC \NR
+\NC xml.remap     \NC show what namespaces are remapped \NC \NR
+\NC lxml.access   \NC report errors with respect to resolving (symbolic) nodes \NC \NR
+\NC lxml.comments \NC show the comments that are encountered (if at all) \NC \NR
+\NC lxml.loading  \NC show what files are loaded and converted \NC \NR
+\NC lxml.setups   \NC show what setups are being associated to elements \NC \NR
+\stoptabulate
+
+In one of our workflows we produce books from \XML\ where the (educational)
+content is organized in many small files. Each book has about 5~chapters and each
+chapter is made of sections that contain text, exercises, resources, etc.\ and so
+the document is assembled from thousands of files (don't worry, runtime inclusion
+is pretty fast). In order to see where in the sources content resides we can
+trace the filename.
+
+\startxmlcmd {\cmdbasicsetup{xmlinclusion}}
+    returns the file where the node comes from
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlinclusions}}
+    returns the list of files where the node comes from
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlbadinclusions}}
+    returns a list of files that were not included due to some problem
+\stopxmlcmd
+
+Of course you have to make sure that these names end up somewhere visible, for
+instance in the margin.
+
+\stopsection
+
+\startsection[title={expansion}]
+
+For novice users the concept of expansion might sound frightening and to some
+extend it is. However, it is important enough to spend some words on it here.
+
+It is good to realize that most setups are sort of immediate. When one setup is
+issued, it can call another one and so on. Normally you won't notice that but
+there are cases where that can be a problem. In \TEX\ you can define a macro,
+take for instance:
+
+\starttyping
+\startxmlsetups xml:foo
+  \def\foobar{\xmlfirst{#1}{/bar}}
+\stopxmlsetups
+\stoptyping
+
+you store the reference top node \type {bar} in \type {\foobar} maybe for later use. In
+this case the content is not yet fetched, it will be done when \type {\foobar} is
+called.
+
+\starttyping
+\startxmlsetups xml:foo
+  \edef\foobar{\xmlfirst{#1}{/bar}}
+\stopxmlsetups
+\stoptyping
+
+Here the content of \type {bar} becomes the body of the macro. But what if
+\type {bar} itself contains elements that also contain elements. When there
+is a setup for \type {bar} it will be triggered and so on.
+
+When that setup looks like:
+
+\starttyping
+\startxmlsetups xml:bar
+  \def\barfoo{\xmlflush{#1}}
+\stopxmlsetups
+\stoptyping
+
+Here we get something like:
+
+\starttyping
+\foobar => {\def\barfoo{...}}
+\stoptyping
+
+When \type {\barfoo} is not defined we get an error and when it is known and expands
+to something weird we might also get an error.
+
+Especially when you don't know what content can show up, this can result in errors
+when an expansion fails, for example because some macro being used is not defined.
+To prevent this we can define a macro:
+
+\starttyping
+\starttexdefinition unexpanded xml:bar:macro #1
+  \def\barfoo{\xmlflush{#1}}
+\stoptexdefinition
+
+\startxmlsetups xml:bar
+  \texdefinition{xml:bar:macro}{#1}
+\stopxmlsetups
+\stoptyping
+
+The setup \type {xml:bar} will still expand but the replacement text now is just the
+call to the macro, think of:
+
+\starttyping
+\foobar => {\texdefinition{xml:bar:macro}{#1}}
+\stoptyping
+
+But this is often not needed, most \CONTEXT\ commands can handle the expansions
+quite well but it's good to know that there is a way out. So, now to some
+examples. Imagine that we have an \XML\ file that looks as follows:
+
+\starttyping
+<?xml version='1.0' ?>
+<demo>
+    <chapter>
+        <title>Some <em>short</em> title</title>
+        <content>
+            zeta
+            <index>
+                <key>zeta</key>
+                <content>zeta again</content>
+            </index>
+            alpha
+            <index>
+                <key>alpha</key>
+                <content>alpha <em>again</em></content>
+            </index>
+            gamma
+            <index>
+                <key>gamma</key>
+                <content>gamma</content>
+            </index>
+            beta
+            <index>
+                <key>beta</key>
+                <content>beta</content>
+            </index>
+            delta
+            <index>
+                <key>delta</key>
+                <content>delta</content>
+            </index>
+            done!
+        </content>
+    </chapter>
+</demo>
+\stoptyping
+
+There are a few structure related elements here: a chapter (with its list entry)
+and some index entries. Both are multipass related and therefore travel around.
+This means that when we let data end up in the auxiliary file, we need to make
+sure that we end up with either expanded data (i.e.\ no references to the \XML\
+tree) or with robust forward and backward references to elements in the tree.
+
+Here we discuss three approaches (and more may show up later): pushing \XML\ into
+the auxiliary file and using references to elements either or not with an
+associated setup. We control the variants with a switch.
+
+\starttyping
+\newcount\TestMode
+
+\TestMode=0 % expansion=xml
+\TestMode=1 % expansion=yes, index, setup
+\TestMode=2 % expansion=yes
+\stoptyping
+
+We apply a couple of setups:
+
+\starttyping
+\startxmlsetups xml:mysetups
+    \xmlsetsetup{\xmldocument}{demo|index|content|chapter|title|em}{xml:*}
+\stopxmlsetups
+
+\xmlregistersetup{xml:mysetups}
+\stoptyping
+
+The main document is processed with:
+
+\starttyping
+\startxmlsetups xml:demo
+    \xmlflush{#1}
+    \subject{contents}
+    \placelist[chapter][criterium=all]
+    \subject{index}
+    \placeregister[index][criterium=all]
+    \page % else buffer is forgotten when placing header
+\stopxmlsetups
+\stoptyping
+
+First we show three alternative ways to deal with the chapter. The first case
+expands the \XML\ reference so that we have an \XML\ stream in the auxiliary
+file. This stream is processed as a small independent subfile when needed. The
+second case registers a reference to the current element (\type {#1}). This means
+that we have access to all data of this element, like attributes, title and
+content. What happens depends on the given setup. The third variant does the same
+but here the setup is part of the reference.
+
+\starttyping
+\startxmlsetups xml:chapter
+    \ifcase \TestMode
+        % xml code travels around
+        \setuphead[chapter][expansion=xml]
+        \startchapter[title=eh: \xmltext{#1}{title}]
+            \xmlfirst{#1}{content}
+        \stopchapter
+    \or
+        % index is used for access via setup
+        \setuphead[chapter][expansion=yes,xmlsetup=xml:title:flush]
+        \startchapter[title=\xmlgetindex{#1}]
+            \xmlfirst{#1}{content}
+        \stopchapter
+    \or
+        % tex call to xml using index is used
+        \setuphead[chapter][expansion=yes]
+        \startchapter[title=hm: \xmlreference{#1}{xml:title:flush}]
+            \xmlfirst{#1}{content}
+        \stopchapter
+    \fi
+\stopxmlsetups
+
+\startxmlsetups xml:title:flush
+    \xmltext{#1}{title}
+\stopxmlsetups
+\stoptyping
+
+We need to deal with emphasis and the content of the chapter.
+
+\starttyping
+\startxmlsetups xml:em
+    \begingroup\em\xmlflush{#1}\endgroup
+\stopxmlsetups
+
+\startxmlsetups xml:content
+    \xmlflush{#1}
+\stopxmlsetups
+\stoptyping
+
+A similar approach is followed with the index entries. Watch how we use the
+numbered entries variant (in this case we could also have used just \type
+{entries} and \type {keys}).
+
+\starttyping
+\startxmlsetups xml:index
+    \ifcase \TestMode
+        \setupregister[index][expansion=xml,xmlsetup=]
+        \setstructurepageregister
+          [index]
+          [entries:1=\xmlfirst{#1}{content},
+           keys:1=\xmltext{#1}{key}]
+    \or
+        \setupregister[index][expansion=yes,xmlsetup=xml:index:flush]
+        \setstructurepageregister
+          [index]
+          [entries:1=\xmlgetindex{#1},
+           keys:1=\xmltext{#1}{key}]
+    \or
+        \setupregister[index][expansion=yes,xmlsetup=]
+        \setstructurepageregister
+          [index]
+          [entries:1=\xmlreference{#1}{xml:index:flush},
+           keys:1=\xmltext{#1}{key}]
+    \fi
+\stopxmlsetups
+
+\startxmlsetups xml:index:flush
+    \xmlfirst{#1}{content}
+\stopxmlsetups
+\stoptyping
+
+Instead of this flush, you can use the predefined setup \type {xml:flush}
+unless it is overloaded by you.
+
+The file is processed by:
+
+\starttyping
+\starttext
+    \xmlprocessfile{main}{test.xml}{}
+\stoptext
+\stoptyping
+
+We don't show the result here. If you're curious what the output is, you can test
+it yourself. In that case it also makes sense to peek into the \type {test.tuc}
+file to see how the information travels around. The \type {metadata} fields carry
+information about how to process the data.
+
+The first case, the \XML\ expansion one, is somewhat special in the sense that
+internally we use small pseudo files. You can control the rendering by tweaking
+the following setups:
+
+\starttyping
+\startxmlsetups xml:ctx:sectionentry
+    \xmlflush{#1}
+\stopxmlsetups
+
+\startxmlsetups xml:ctx:registerentry
+    \xmlflush{#1}
+\stopxmlsetups
+\stoptyping
+
+{\em When these methods work out okay the other structural elements will be
+dealt with in a similar way.}
+
+\stopsection
+
+\startsection[title={special cases}]
+
+Normally the content will be flushed under a special (so called) catcode regime.
+This means that characters that have a special meaning in \TEX\ will have no such
+meaning in an \XML\ file. If you want content to be treated as \TEX\ code, you can
+use one of the following:
+
+\startxmlcmd {\cmdbasicsetup{xmlflushcontext}}
+    flush the given \cmdinternal {cd:node} using the \TEX\ character
+    interpretation scheme
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlcontext}}
+    flush the match of \cmdinternal {cd:lpath} for the given \cmdinternal
+    {cd:node} using the \TEX\ character interpretation scheme
+\stopxmlcmd
+
+We use this in cases like:
+
+\starttyping
+....
+  \xmlsetsetup {#1} {
+      tm|texformula|
+  } {xml:*}
+....
+
+\startxmlsetups xml:tm
+  \mathematics{\xmlflushcontext{#1}}
+\stopxmlsetups
+
+\startxmlsetups xml:texformula
+  \placeformula\startformula\xmlflushcontext{#1}\stopformula
+\stopxmlsetups
+\stoptyping
+
+\stopsection
+
+\startsection[title={collecting}]
+
+Say that your document has
+
+\starttyping
+<table>
+    <tr>
+        <td>foo</td>
+        <td>bar<td>
+    </tr>
+</table>
+\stoptyping
+
+And that you need to convert that to \TEX\ speak like:
+
+\starttyping
+\bTABLE
+    \bTR
+        \bTD foo \eTD
+        \bTD bar \eTD
+    \eTR
+\eTABLE
+\stoptyping
+
+A simple mapping is:
+
+\starttyping
+\startxmlsetups xml:table
+    \bTABLE \xmlflush{#1} \eTABLE
+\stopxmlsetups
+\startxmlsetups xml:tr
+    \bTR \xmlflush{#1} \eTR
+\stopxmlsetups
+\startxmlsetups xml:td
+    \bTD \xmlflush{#1} \eTD
+\stopxmlsetups
+\stoptyping
+
+The \type {\bTD} command is a so called delimited command which means that it
+picks up its argument by looking for an \type {\eTD}. For the simple case here
+this works quite well because the flush is inside the pair. This is not the case
+in the following variant:
+
+\starttyping
+\startxmlsetups xml:td:start
+    \bTD
+\stopxmlsetups
+\startxmlsetups xml:td:stop
+    \eTD
+\stopxmlsetups
+\startxmlsetups xml:td
+    \xmlsetup{#1}{xml:td:start}
+    \xmlflush{#1}
+    \xmlsetup{#1}{xml:td:stop}
+\stopxmlsetups
+\stoptyping
+
+When for some reason \TEX\ gets confused you can revert to a mechanism that
+collects content.
+
+\starttyping
+\startxmlsetups xml:td:start
+    \startcollect
+        \bTD
+    \stopcollect
+\stopxmlsetups
+\startxmlsetups xml:td:stop
+    \startcollect
+        \eTD
+    \stopcollect
+\stopxmlsetups
+\startxmlsetups xml:td
+    \startcollecting
+        \xmlsetup{#1}{xml:td:start}
+        \xmlflush{#1}
+        \xmlsetup{#1}{xml:td:stop}
+    \stopcollecting
+\stopxmlsetups
+\stoptyping
+
+You can even implement solutions that effectively do this:
+
+\starttyping

+\stopbuffer
+
+\typebuffer[foo]
+
+First we show how to plug in a directive. Processing instructions like the
+following are normally ignored by an \XML\ processor, unless they make sense
+to it.
+
+\starttyping
+<?context-directive message info 1: this is a demo file ?>
+<?context-message-directive info 2: this is a demo file ?>
+\stoptyping
+
+We can define a message handler as follows:
+
+\startbuffer
+\def\MyMessage#1#2#3{\writestatus{#1}{#2 #3}}
+
+\xmlinstalldirective{message}{MyMessage}
+\stopbuffer
+
+\typebuffer \getbuffer
+
+When this file is processed you will see this on the console:
+
+\starttyping
+info > 1: this is a demo file
+info > 2: this is a demo file
+\stoptyping
+
+The file has some sections that can be used or ignored. The recipe for
+obeying \type {t1} and \type {t4} is the following:
+
+\startbuffer
+\xmlsetinjectors[t1]
+\xmlsetinjectors[t4]
+
+\startxmlsetups xml:initialize
+    \xmlapplyselectors{#1}
+    \xmlsetsetup {#1} {
+        one|two|three|four
+    } {xml:*}
+\stopxmlsetups
+
+\xmlregistersetup{xml:initialize}
+
+\startxmlsetups xml:one
+    [ONE \xmlflush{#1} ONE]
+\stopxmlsetups
+
+\startxmlsetups xml:two
+    [TWO \xmlflush{#1} TWO]
+\stopxmlsetups
+
+\startxmlsetups xml:three
+    [THREE \xmlflush{#1} THREE]
+\stopxmlsetups
+
+\startxmlsetups xml:four
+    [FOUR \xmlflush{#1} FOUR]
+\stopxmlsetups
+\stopbuffer
+
+\typebuffer \getbuffer
+
+This typesets:
+
+\startnarrower
+\xmlprocessbuffer{main}{foo}{}
+\stopnarrower
+
+The include coding is kind of special: it permits adding content (in a comment)
+and ignoring the rest so that we indeed can add something without interfering
+with the original. Of course in a normal workflow such messy solutions are
+not needed, but alas, often workflows are not that clean, especially when one
+has no real control over the source.
+
+\startxmlcmd {\cmdbasicsetup{xmlsetinjectors}}
+    enables a list of injectors that will be used
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlresetinjectors}}
+    resets the list of injectors
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlinjector}}
+    expands an injection (command); normally this one is only used
+    (in some setup) or for testing
+\stopxmlcmd
+
+\startxmlcmd {\cmdbasicsetup{xmlapplyselectors}}
+    analyze the tree \cmdinternal {cd:node} for marked sections that
+    will be injected
+\stopxmlcmd
+
+We have some injections predefined:
+
+\starttyping
+\startsetups xml:directive:injector:page
+    \page
+\stopsetups
+
+\startsetups xml:directive:injector:column
+    \column
+\stopsetups
+
+\startsetups xml:directive:injector:blank
+    \blank
+\stopsetups
+\stoptyping
+
+In the example we see:
+
+\starttyping
+<?context-directive injector page t7 t8 ?>
+\stoptyping
+
+When we set \type {\xmlsetinjector[t7]} a pagebreak will injected in that spot.
+Tags like \type {t7}, \type {t8} etc.\ can represent versions.
+

+\stopxmlsetups

+\stoptext
+\stopbuffer
+
+Say that you have the following \XML\ setup:
+
+\typebuffer[pre-xml]
+
+and that (such things happen) the input looks like this:
+
+\startbuffer[demo]
+<root>
+BAD TITLE: crap crap crap ...
+
+BAD TITLE: crap crap crap ...
+</root>
+\stopbuffer
+
+\typebuffer[demo]
+
+You can then clean up these \type {BAD TITLE}'s as follows:
+
+\typebuffer[pre-code]
+
+and get as result:
+
+\start \getbuffer[pre-code,pre-xml] \stop
+
+The preprocessor function gets as second argument the current settings, an d
+the field \type {currentresource} can be used to limit the actions to
+specific resources, in our case it's \type {buffer: demo}. Afterwards you can
+reset the proprocessor with:
+
+\startluacode
+lxml.preprocessor = nil
+\stopluacode
+
+Future versions might give some more control over preprocessors. For now consider
+it to be a quick hack.

-\startchapter[title={Introduction}]
-
-This manual presents the \MKIV\ way of dealing with \XML. Although the
-traditional \MKII\ streaming parser has a charming simplicity in its control, for
-complex documents the tree based \MKIV\ method is more convenient. It is for this
-reason that the old method has been removed from \MKIV. If you are familiar with
-\XML\ processing in \MKII, then you will have noticed that the \MKII\ commands
-have \type {XML} in their name. The \MKIV\ commands have a lowercase \type {xml}
-in their names. That way there is no danger for confusion or a mixup.
-
-You may wonder why we do these manipulations in \TEX\ and not use \XSLT\ (or
-other transformation methods) instead. The advantage of an integrated approach is
-that it simplifies usage. Think of not only processing the document, but also
-using \XML\ for managing resources in the same run. An \XSLT\ approach is just as
-verbose (after all, you still need to produce \TEX\ code) and probably less
-readable. In the case of \MKIV\ the integrated approach is also faster and gives
-us the option to manipulate content at runtime using \LUA. It has the additional
-advantage that to some extend we can handle a mix of \TEX\ and \XML\ because we
-know when we're doing one or the other.
-
-This manual is dedicated to Taco Hoekwater, one of the first \CONTEXT\ users, and
-also the first to use it for processing \XML. Who could have thought at that time
-that we would have a more convenient way of dealing with those angle brackets.
-The second version for this manual is dedicated to Thomas Schmitz, a power user
-who occasionally became victim of the evolving mechanisms.

-\startchapter[title={Setting up a converter}]
-
-\startsection[title={from structure to setup}]
-
-We use a very simple document structure for demonstrating how a converter is
-defined. In practice a mapping will be more complex, especially when we have a
-style with complex chapter openings using data coming from all kind of places,
-different styling of sections with the same name, selectively (out of order)
-flushed content, special formatting, etc.
-
-\typefile{manual-demo-1.xml}
-
-Say that this document is stored in the file \type {demo.xml}, then the following
-code can be used as starting point:
-
-\starttyping
-\startxmlsetups xml:demo:base
-  \xmlsetsetup{#1}{document|section|p}{xml:demo:*}
-\stopxmlsetups
-
-\xmlregisterdocumentsetup{demo}{xml:demo:base}
-
-\startxmlsetups xml:demo:document
-  \starttitle[title={Contents}]
-    \placelist[chapter]
-  \stoptitle
-  \xmlflush{#1}
-\stopxmlsetups
-
-\startxmlsetups xml:demo:section
-  \startchapter[title=\xmlfirst{#1}{/title}]
-    \xmlfirst{#1}{/content}
-  \stopchapter
-\stopxmlsetups
-
-\startxmlsetups xml:demo:p
-  \xmlflush{#1}\endgraf
-\stopxmlsetups
-
-\xmlprocessfile{demo}{demo.xml}{}
-\stoptyping
-
-Watch out! These are not just setups, but specific \XML\ setups which get an
-argument passed (the \type {#1}). If for some reason your \XML\ processing fails,
-it might be that you mistakenly have used a normal setup definition. The argument
-\type {#1} represents the current node (element) and is a unique identifier. For
-instance a \type {<p>..</p>} can have an identifier {demo::5}. So, we can get
-something:
-
-\starttyping
-\xmlflush{demo::5}\endgraf
-\stoptyping
-
-but as well:
-
-\starttyping
-\xmlflush{demo::6}\endgraf
-\stoptyping
-
-Keep in mind that the references tor the actual nodes (elements) are
-abstractions, you never see those \type {<id>::<number>}'s, because we will use
-either the abstract \type {#1} (any node) or an explicit reference like \type
-{demo}. The previous setup when issued will be like:
-
-\starttyping
-\startchapter[title=\xmlfirst{demo::3}{/title}]
-  \xmlfirst{demo::4}{/content}
-\stopchapter
-\stoptyping
-
-Here the \type {title} is used to typeset the chapter title but also for an entry
-in the table of contents. At the moment the title is typeset the \XML\ node gets
-looked up and expanded in real text. However, for the list it gets stored for
-later use. One can argue that this is not needed for \XML, because one can just
-filter all the titles and use page references, but then one also looses the
-control one normally has over such titles. For instance it can be that some
-titles are rendered differently and for that we need to keep track of usage.
-Doing that with transformations or filtering is often more complex than leaving
-that to \TEX. As soon as the list gets typeset, the reference (\type {demo::#3})
-is used for the lookup. This is because by default the title is stored as given.
-So, as long as we make sure the \XML\ source is loaded before the table of
-contents is typeset we're ok. Later we will look into this in more detail, for
-now it's enough to know that in most cases the abstract \type {#1} reference will
-work out ok.
-
-Contrary to the style definitions this interface looks rather low level (with no
-optional arguments) and the main reason for this is that we want processing to be
-fast. So, the basic framework is:
-
-\starttyping
-\startxmlsetups xml:demo:base
-  % associate setups with elements
-\stopxmlsetups
-
-\xmlregisterdocumentsetup{demo}{xml:demo:base}
-
-% define setups for matches
-
-\xmlprocessfile{demo}{demo.xml}{}
-\stoptyping
-
-In this example we mostly just flush the content of an element and in the case of
-a section we flush explicit child elements. The \type {#1} in the example code
-represents the current element. The line:
-
-\starttyping
-\xmlsetsetup{demo}{*}{-}
-\stoptyping
-
-sets the default for each element to \quote {just ignore it}. A \type {+} would
-make the default to always flush the content. This means that at this point we
-only handle:
-
-\starttyping
-<section>
-  <title>Some title</title>
-  <content>
-    <p>a paragraph of text</p>
-  </content>
-</section>
-\stoptyping
-
-In the next section we will deal with the slightly more complex itemize and
-figure placement. At first sight all these setups may look overkill but keep in
-mind that normally the number of elements is rather limited. The complexity is
-often in the style and having access to each snippet of content is actually
-quite handy for that.
-
-\stopsection
-
-\startsection[title={alternative solutions}]
-
-Dealing with an itemize is rather simple (as long as we forget about
-attributes that control the behaviour):
-
-\starttyping
-<itemize>
-  <item>first</item>
-  <item>second</item>
-</itemize>
-\stoptyping
-
-First we need to add \type {itemize} to the setup assignment (unless we've used
-the wildcard \type {*}):
-
-\starttyping
-\xmlsetsetup{demo}{document|section|p|itemize}{xml:demo:*}
-\stoptyping
-
-The setup can look like:
-
-\starttyping
-\startxmlsetups xml:demo:itemize
-  \startitemize
-    \xmlfilter{#1}{/item/command(xml:demo:itemize:item)}
-  \stopitemize
-\stopxmlsetups
-
-\startxmlsetups xml:demo:itemize:item
-  \startitem
-    \xmlflush{#1}
-  \stopitem
-\stopxmlsetups
-\stoptyping
-
-An alternative is to map item directly:
-
-\starttyping
-\xmlsetsetup{demo}{document|section|p|itemize|item}{xml:demo:*}
-\stoptyping
-
-and use:
-
-\starttyping
-\startxmlsetups xml:demo:itemize
-  \startitemize
-    \xmlflush{#1}
-  \stopitemize
-\stopxmlsetups
-
-\startxmlsetups xml:demo:item
-  \startitem
-    \xmlflush{#1}
-  \stopitem
-\stopxmlsetups
-\stoptyping
-
-Sometimes, a more local solution using filters and \type {/command(...)} makes more
-sense, especially when the \type {item} tag is used for other purposes as well.
-
-Explicit flushing with \type {command} is definitely the way to go when you have
-complex products. In one of our projects we compose math school books from many
-thousands of small \XML\ files, and from one source set several products are
-typeset. Within a book sections get done differently, content gets used, ignored
-or interpreted differently depending on the kind of content, so there is a
-constant checking of attributes that drive the rendering. In that a generic setup
-for a title element makes less sense than explicit ones for each case. (We're
-talking of huge amounts of files here, including multiple images on each rendered
-page.)
-
-When using \type {command} you can pass two arguments, the first is the setup for
-the match, the second one for the miss, as in:
-
-\starttyping
-\xmlfilter{#1}{/element/command(xml:true,xml:false)}
-\stoptyping
-
-Back to the example, this leaves us with dealing with the resources, like
-figures:
-
-\starttyping
-<resource type='figure'>
-  <caption>A picture of a cow.</caption>
-  <content><external file="cow.pdf"/></content>
-</resource>
-\stoptyping
-
-Here we can use a more restricted match:
-
-\starttyping
-\xmlsetsetup{demo}{resource[@type='figure']}{xml:demo:figure}
-\xmlsetsetup{demo}{external}{xml:demo:*}
-\stoptyping
-
-and the definitions:
-
-\starttyping
-\startxmlsetups xml:demo:figure
-  \placefigure
-    {\xmlfirst{#1}{/caption}}
-    {\xmlfirst{#1}{/content}}
-\stopxmlsetups
-
-\startxmlsetups xml:demo:external
-  \externalfigure[\xmlatt{#1}{file}]
-\stopxmlsetups
-\stoptyping
-
-At this point it is good to notice that \type {\xmlatt{#1}{file}} is passed as it
-is: a macro call. This means that when a macro like \type {\externalfigure} uses
-the first argument frequently without first storing its value, the lookup is done
-several times. A solution for this is:
-
-\starttyping
-\startxmlsetups xml:demo:external
-  \expanded{\externalfigure[\xmlatt{#1}{file}]}
-\stopxmlsetups
-\stoptyping
-
-Because the lookup is rather fast, normally there is no need to bother about this
-too much because internally \CONTEXT\ already makes sure such expansion happens
-only once.
-
-An alternative definition for placement is the following:
-
-\starttyping
-\xmlsetsetup{demo}{resource}{xml:demo:resource}
-\stoptyping
-
-with:
-
-\starttyping
-\startxmlsetups xml:demo:resource
-  \placefloat
-    [\xmlatt{#1}{type}]
-    {\xmlfirst{#1}{/caption}}
-    {\xmlfirst{#1}{/content}}
-\stopxmlsetups
-\stoptyping
-
-This way you can specify \type {table} as type too. Because you can define your
-own float types, more complex variants are also possible. In that case it makes
-sense to provide some default behaviour too:
-
-\starttyping
-\definefloat[figure-here][figure][default=here]
-\definefloat[figure-left][figure][default=left]
-\definefloat[table-here] [table] [default=here]
-\definefloat[table-left] [table] [default=left]
-
-\startxmlsetups xml:demo:resource
-  \placefloat
-    [\xmlattdef{#1}{type}{figure}-\xmlattdef{#1}{location}{here}]
-    {\xmlfirst{#1}{/caption}}
-    {\xmlfirst{#1}{/content}}
-\stopxmlsetups
-\stoptyping
-
-In this example we support two types and two locations. We default to a figure
-placed (when possible) at the current location.

-\startsection[title={\TEX\ versus \LUA}]
-
-It will not come as a surprise that we can access \XML\ files from \TEX\ as well
-as from \LUA. In fact there are two methods to deal with \XML\ in \LUA. First
-there are the low level \XML\ functions in the \type {xml} namespace. On top of
-those functions there is a set of functions in the \type {lxml} namespace that
-deals with \XML\ in a more \TEX ie way. Most of these have similar commands at
-the \TEX\ end.
-
-\startbuffer
-\startxmlsetups first:demo:one
-  \xmlfilter {#1} {artist/name[text()='Randy Newman']/..
-    /albums/album[position()=3]/command(first:demo:two)}
-\stopxmlsetups
-
-\startxmlsetups first:demo:two
-  \blank \start \tt
-    \xmldisplayverbatim{#1}
-  \stop \blank
-\stopxmlsetups
-
-\xmlprocessfile{demo}{music-collection.xml}{first:demo:one}
-\stopbuffer
-
-\typebuffer
-
-This gives the following snippet of verbatim \XML\ code. The indentation is
-conform the indentation in the whole \XML\ file. \footnote {The (probably
-outdated) \XML\ file contains the collection stores on my slimserver instance.
-You can use the \type {mtxrun --script flac} to generate such files.}
-
-\doifmodeelse {atpragma} {
-    \getbuffer
-} {
-    \typefile{xml-mkiv-01.xml}
-}
-
-An alternative written in \LUA\ looks as follows:
-
-\startbuffer
-\blank \start \tt \startluacode
-  local m = lxml.load("mine","music-collection.xml") -- m == lxml.id("mine")
-  local p = "artist/name[text()='Randy Newman']/../albums/album[position()=4]"
-  local l = lxml.filter(m,p) -- returns a list (with one entry)
-  lxml.displayverbatim(l[1])
-\stopluacode \stop \blank
-\stopbuffer
-
-\typebuffer
-
-This produces:
-
-\doifmodeelse {atpragma} {
-    \getbuffer
-} {
-    \typefile{xml-mkiv-02.xml}
-}
-
-You can use both methods mixed but in practice we will use the \TEX\ commands in
-regular styles and the mixture in modules, for instance in those dealing with
-\MATHML\ and cals tables. For complex matters you can write your own finalizers
-(the last action to be taken in a match) in \LUA\ and use them at the \TEX\ end.
-
-\stopsection
-
-\startsection[title={a few details}]
-
-In \CONTEXT\ setups are a rather common variant on macros (\TEX\ commands) but
-with their own namespace. An example of a setup is:
-
-\starttyping
-\startsetup doc:print
-  \setuppapersize[A4][A4]
-\stopsetup
-
-\startsetup doc:screen
-  \setuppapersize[S6][S4]
-\stopsetup
-\stoptyping
-
-Given the previous definitions, later on we can say something like:
-
-\starttyping
-\doifmodeelse {paper} {
-  \setup[doc:print]
-} {
-  \setup[doc:screen]
-}
-\stoptyping
-
-Another example is:
-
-\starttyping
-\startsetup[doc:header]
-  \marking[chapter]
-  \space
-  --
-  \space
-  \pagenumber
-\stopsetup
-\stoptyping
-
-in combination with:
-
-\starttyping
-\setupheadertexts[\setup{doc:header}]
-\stoptyping
-
-Here the advantage is that instead of ending up with an unreadable header
-definitions, we use a nicely formatted setup. An important property of setups and
-the reason why they were introduced long ago is that spaces and newlines are
-ignored in the definition. This means that we don't have to worry about so called
-spurious spaces but it also means that when we do want a space, we have to use
-the \type {\space} command.
-
-The only difference between setups and \XML\ setups is that the following ones
-get an argument (\type {#1}) that reflects the current node in the \XML\ tree.
-
-\stopsection
-
-\startsection[title={CDATA}]
-
-What to do with \type {CDATA}? There are a few methods at tle \LUA\ end for
-dealing with it but here we just mention how you can influence the rendering.
-There are four macros that play a role here:
-
-\starttyping
-\unexpanded\def\xmlcdataobeyedline {\obeyedline}
-\unexpanded\def\xmlcdataobeyedspace{\strut\obeyedspace}
-\unexpanded\def\xmlcdatabefore     {\begingroup\tt}
-\unexpanded\def\xmlcdataafter      {\endgroup}
-\stoptyping
-
-Technically you can overload them but beware of side effects. Normally you won't
-see much \type {CDATA} and whenever we do, it involves special data that needs
-very special treatment anyway.
-
-\stopsection
-
-\startsection[title={Entities}]
-
-As usual with any way of encoding documents you need escapes in order to encode
-the characters that are used in tagging the content, embedding comments, escaping
-special characters in strings (in programming languages), etc. In \XML\ this
-means that in order characters like \type {<} you need an escape like \type
-{&lt;} and in order then to encode an \type {&} you need \type {&amp;}.
-
-In a typesetting workflow using a programming language like \TEX, another problem
-shows up. There we have different special characters, like \type {$ $} for triggering
-math, but also the backslash, braces etc. Even one such special character is already
-enough to have yet another escaping mechanism at work.
-
-Ideally a user should not worry about these issues but it helps figuring out issues
-when you know what happens under the hood. Also it is good to know that in the
-code there are several ways to deal with these issues. Take the following document:
-
-\starttyping
-<text>
-    Here we have a bit of a &lt;&mess&gt;:
-
-    # &#35;
-    % &#37;
-    \ &#92;
-    { &#123;
-    | &#124;
-    } &#125;
-    ~ &#126;
-</text>
-\stoptyping
-
-When the file is read the \type {&lt;} entity will be replaced by \type {<} and
-the \type {&gt;} by \type {>}. The numeric entities will be replaced by the
-characters they refer to. The \type {&mess} is kind of special. We do preload
-a huge list of more or less standardized entities but \type {mess} is not in
-there. However, it is possible to have it defined in the document preamble, like:
-
-\starttyping
-<!DOCTYPE dummy SYSTEM "dummy.dtd" [
-    <!ENTITY mess "what a mess" >
-]>
-\stoptyping
-
-or even this:
-
-\starttyping
-<!DOCTYPE dummy SYSTEM "dummy.dtd" [
-    <!ENTITY mess "<p>what a mess</p>" >
-]>
-\stoptyping
-
-You can also define it in your document style using one of:
-
-\startxmlcmd {\cmdbasicsetup{xmlsetentity}}
-    replaces entity with name \cmdinternal {cd:name} by \cmdinternal {cd:text}
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmltexentity}}
-    replaces entity with name \cmdinternal {cd:name} by \cmdinternal {cd:text}
-    typeset under a \TEX\ regime
-\stopxmlcmd
-
-Such a definition will always have a higher priority than the one defined
-in the document. Anyway, when the document is read in all entities are
-resolved and those that need a special treatment because they map to some
-text are stored in such a way that we can roundtrip them. As a consequence,
-as soon as the content gets pushed into \TEX, we need not only to intercept
-special characters but also have to make sure that the following works:
-
-\starttyping
-\xmltexentity {tex} {\TEX}
-\stoptyping
-
-Here the backslash starts a control sequence while in regular content a
-backslash is just that: a backslash.
-
-Special characters are really special when we have to move text around
-in a \TEX\ ecosystem.
-
-\starttyping
-<text>
-    <title>About #3</title>
-</text>
-\stoptyping
-
-If we map and define title as follows:
-
-\starttyping
-\startxmlsetup xml:title
-    \title{\xmlflush{#1}}
-\stopxmlsetup
-\stoptyping
-
-normally something \type {\xmlflush {id::123}} will be written to the
-auxiliary file and in most cases that is quite okay, but if we have this:
-
-\starttyping
-\setuphead[title][expansion=yes]
-\stoptyping
-
-then we don't want the \type {#} to end up as hash because later on \TEX\
-can get very confused about it because it sees some argument then in a
-probably unexpected way. This is solved by escaping the hash like this:
-
-\starttyping
-About \Ux{23}3
-\stoptyping
-
-The \type {\Ux} command will convert its hexadecimal argument into a
-character. Of course one then needs to typeset such a text under a \TEX\
-character regime but that is normally the case anyway.

-\startchapter[title={Commands}]
-
-\startsection[title={nodes and lpaths}]
-
-The amount of commands available for manipulating the \XML\ file is rather large.
-Many of the commands cooperate with the already discussed setups, a fancy name
-for a collection of macro calls either or not mixed with text.
-
-Most of the commands are just shortcuts to \LUA\ calls, which means that the real
-work is done by \LUA. In fact, what happens is that we have a continuous transfer
-of control from \TEX\ to \LUA, where \LUA\ prints back either data (like element
-content or attribute values) or just invokes a setup whereby it passes a
-reference to the node resolved conform the path expression. The invoked setup
-itself might return control to \LUA\ again, etc.
-
-This sounds complicated but examples will show what we mean here. First we
-present the whole repertoire of commands. Because users can read the source code,
-they might uncover more commands, but only the ones discussed here are official.
-The commands are grouped in categories.
-
-In the following sections \cmdinternal {cd:node} means a reference to a node:
-this can be the identifier of the root (the loaded xml tree) or a reference to a
-node in that tree (often the result of some lookup. A \cmdinternal {cd:lpath} is
-a fancy name for a path expression (as with \XSLT) but resolved by \LUA.
-
-\stopsection
-
-\startsection[title={commands}]
-
-There are a lot of commands available but you probably can ignore most of them.
-We try to be complete which means that there is for instance \type {\xmlfirst} as
-well as \type {\xmllast} but you probably never need the last one. There are also
-commands that were used when testing this interface and we see no reason to
-remove them. Some obscure ones are used in modules and after a while even I often
-forget that they exist. To give you an idea of what commands are important we
-show their use in generating the \CONTEXT\ command definitions (\type
-{x-set-11.mkiv}) per Januari 2016:

-
-You can use \LUA\ code to manipulate the tree and it makes no sense to duplicate
-this in \TEX. In the future we might provide an interface to some of this
-functionality. Keep in mind that manipuating the tree might have side effects as
-we maintain several indices into the tree that also needs to be updated then.

-\startsection[title={integration}]
-
-If you write a module that deals with \XML, for instance processing cals tables,
-then you need ways to control specific behaviour. For instance, you might want to
-add a background to the table. Such directives are collected in \XML\ files and
-can be loaded on demand.
-
-\startxmlcmd {\cmdbasicsetup{xmlloaddirectives}}
-    loads \CONTEXT\ directives from \cmdinternal {cd:file} that will get
-    interpreted when processing documents
-\stopxmlcmd
-
-A directives definition file looks as follows:
-
-\starttyping
-<?xml version="1.0" standalone="yes"?>
-
-<directives>
-  <directive attribute='id' value="100"
-    setup="cdx:100"/>
-  <directive attribute='id' value="101"
-    setup="cdx:101"/>
-  <directive attribute='cdx' value="colors" element="cals:table"
-    setup="cdx:cals:table:colors"/>
-  <directive attribute='cdx' value="vertical" element="cals:table"
-    setup="cdx:cals:table:vertical"/>
-  <directive attribute='cdx' value="noframe" element="cals:table"
-    setup="cdx:cals:table:noframe"/>
-  <directive attribute='cdx' value="*" element="cals:table"
-    setup="cdx:cals:table:*"/>
-</directives>
-\stoptyping
-
-Examples of usage can be found in \type {x-cals.mkiv}. The directive is triggered
-by an attribute. Instead of a setup you can specify a setup to be applied before
-and after the node gets flushed.
-
-\startxmlcmd {\cmdbasicsetup{xmldirectives}}
-    apply the setups directive associated with the node
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmldirectivesbefore}}
-    apply the before directives associated with the node
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmldirectivesafter}}
-    apply the after directives associated with the node
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlinstalldirective}}
-    defines a directive that hooks into a handler
-\stopxmlcmd
-
-Normally a directive will be put in the \XML\ file, for instance as:
-
-\starttyping
-<?context-mathml-directive minus reduction yes ?>
-\stoptyping
-
-Here the \type {mathml} is the general class of directives and \type {minus} a
-subclass, in our case a specific element.
-
-\stopsection
-
-\startsection[title={setups}]
-
-The basic building blocks of \XML\ processing are setups. These are just
-collections of macros that are expanded. These setups get one argument passed
-(\type {#1}):
-
-\starttyping
-\startxmlsetups somedoc:somesetup
-    \xmlflush{#1}
-\stopxmlsetups
-\stoptyping
-
-This argument is normally a number that internally refers to a specific node in
-the \XML\ tree. The user should see it as an abstract reference and not depend on
-its numeric property. Just think of it as \quote {the current node}. You can (and
-probably will) call such setups using:
-
-\startxmlcmd {\cmdbasicsetup{xmlsetup}}
-    expands setup \cmdinternal {cd:setup} and pass \cmdinternal {cd:node} as
-    argument
-\stopxmlcmd
-
-However, in most cases the setups are associated to specific elements,
-something that users of \XSLT\ might recognize as templates.
-
-\startxmlcmd {\cmdbasicsetup{xmlsetfunction}}
-    associates function \cmdinternal {cd:luafunction} to the elements in
-    namespace \cmdinternal {cd:name} that match \cmdinternal {cd:lpath}

-The general setup command (not to be confused with setups) that deals with the

-
-\cmdfullsetup{setupxml}
-
-When you set \type {default} to \cmdinternal {cd:text} elements with no setup
-assigned will end up as text. When set to \type {hidden} such elements will be

-Often an attribute will determine the rendering and this may result in many
-tests. Especially when we have multiple attributes that control the output such
-tests can become rather extensive and redundant because one gets $n\times m$ or
-more such tests.
-
-Therefore we have a convenient way to map attributes onto for instance strings or
-commands.
-
-\startxmlcmd {\cmdbasicsetup{xmlmapvalue}}
-    associate a \cmdinternal {cd:text} with a \cmdinternal {cd:category} and
-    \cmdinternal {cd:name} (alias: \type{\xmlmapval})
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlvalue}}

-\startxmlcmd {\cmdbasicsetup{xmldoifelsevalue}}
-    associate a \cmdinternal {cd:text} with a \cmdinternal {cd:category} and

-\stopxmlcmd
-
-This is used as follows. We define a couple of mappings in the same category:
-
-\starttyping
-\xmlmapvalue{emph}{bold}  {\bf}
-\xmlmapvalue{emph}{italic}{\it}
-\stoptyping
-
-Assuming that we have associated the following setup with the \type {emph}
-element, we can say (with \type {#1} being the current element):
-
-\starttyping
-\startxmlsetups demo:emph
-  \begingroup
-    \xmlvalue{emph}{\xmlatt{#1}{type}}{}
-  \endgroup
-\stopxmlsetups
-\stoptyping
-
-In this case we have no default. The \type {type} attribute triggers the actions,
-as in:
-
-\starttyping
-normal <emph type='bold'>bold</emph> normal
-\stoptyping
-
-This mechanism is not really bound to elements and attributes so you can use this
-mechanism for other purposes as well.

-\startsection[title={path expressions}]
-
-In the previous chapters we used \cmdinternal {cd:lpath} expressions, which are a variant
-on \type {xpath} expressions as in \XSLT\ but in this case more geared towards
-usage in \TEX. This mechanisms will be extended when demands are there.
-
-A path is a sequence of matches. A simple path expression is:
-
-\starttyping
-a/b/c/d
-\stoptyping
-
-Here each \type {/} goes one level deeper. We can go backwards in a lookup with
-\type {..}:
-
-\starttyping
-a/b/../d
-\stoptyping
-
-We can also combine lookups, as in:
-
-\starttyping
-a/(b|c)/d
-\stoptyping
-
-A negated lookup is preceded by a \type {!}:
-
-\starttyping
-a/(b|c)/!d
-\stoptyping
-
-A wildcard is specified with a \type {*}:
-
-\starttyping
-a/(b|c)/!d/e/*/f
-\stoptyping
-
-In addition to these tag based lookups we can use attributes:
-
-\starttyping
-a/(b|c)/!d/e/*/f[@type=whatever]
-\stoptyping
-
-An \type {@} as first character means that we are dealing with an attribute.
-Within the square brackets there can be boolean expressions:
-
-\starttyping
-a/(b|c)/!d/e/*/f[@type=whatever and @id>100]
-\stoptyping
-
-You can use functions as in:
-
-\starttyping
-a/(b|c)/!d/e/*/f[something(text()) == "oeps"]
-\stoptyping
-
-There are a couple of predefined functions:
-
-\starttabulate[|l|l|p|]
-\NC \type{rootposition} \type{order} \NC number \NC the index of the matched root element (kind of special) \NC \NR
-\NC \type{position}                  \NC number \NC the current index of the matched element in the match list \NC \NR
-\NC \type{match}                     \NC number \NC the current index of the matched element sub list with the same parent \NC \NR

-There are fundamental differences between \type {position}, \type {match} and
-\type {index}. Each step results in a new list of matches. The \type {position}
-is the index in this new (possibly intermediate) list. The \type {match} is also
-an index in this list but related to the specific match of element names. The
-\type {index} refers to the location in the parent element.

-Say that we have:

-In most cases the \type {position} test is more restrictive than the \type
-{match} test.
-
-You can pass your own functions too. Such functions are defined in the the \type
-{xml.expressions} namespace. We have defined a few shortcuts:

-You can also use normal \LUA\ functions as long as you make sure that you pass

-The given expression between \type {[]} is converted to a \LUA\ expression so you
-can use the usual operators:
-
-\starttyping
-== ~= <= >= < > not and or ()
-\stoptyping
-
-In addition, \type {=} equals \type {==} and \type {!=} is the same as \type
-{~=}. If you mess up the expression, you quite likely get a \LUA\ error message.

-The \CSS\ approach to filtering is a bit different from the path based one and is
-supported too. In fact, you can combine both methods. Depending on what you
-select, the \CSS\ one can be a little bit faster too. It has the advantage that
-one can select more in one go but at the same time looks a bit less attractive.
-This method was added just to show that it can be done but might be useful too. A
-selector is given between curly braces (after all \CSS\ uses them and they have no
-function yet in the parser.

-The next pages show some examples. For that we use the demo file:
-
-\typebuffer[selector-001]
-
-The class and id selectors often only make sense in \HTML\ like documents but they
-are supported nevertheless. They are after all just shortcuts for filtering by
-attribute. The class filtering is special in the sense that it checks for a class
-in a list of classes given in an attribute.
-
-\showCSSdemo{selector-001}{{.one}}
-\showCSSdemo{selector-001}{{.one, .two}}
-\showCSSdemo{selector-001}{{.one, .two, \letterhash first}}
-
-Attributes can be filtered by presence, value, partial value and such. Quotes are
-optional but we advice to use them.
-
-\showCSSdemo{selector-001}{{[foo], [bar=foo]}}
-\showCSSdemo{selector-001}{{[bar\lettertilde=foo]}}
-\showCSSdemo{selector-001}{{[bar\letterhat="foo"]}}
-\showCSSdemo{selector-001}{{[whatever\lettertilde="five"]}}
-
-You can of course combine the methods as in:
-
-\showCSSdemo{selector-001}{{g f .one, g f .three}}
-\showCSSdemo{selector-001}{{g > f .one, g > f .three}}
-\showCSSdemo{selector-001}{{d + e}}
-\showCSSdemo{selector-001}{{d ~ e}}
-\showCSSdemo{selector-001}{{d ~ e, g f .one, g f .three}}
-
-You can also negate the result by using \type {:not} on a simple expression:
-
-\showCSSdemo{selector-001}{{:not([whatever\lettertilde="five"])}}
-\showCSSdemo{selector-001}{{:not(d)}}
-
-The child and match selectors are also supported:
-
-\showCSSdemo{selector-001}{{a:nth-child(3)}}
-\showCSSdemo{selector-001}{{a:nth-last-child(3)}}
-\showCSSdemo{selector-001}{{g:nth-of-type(3)}}
-\showCSSdemo{selector-001}{{g:nth-last-of-type(3)}}
-\showCSSdemo{selector-001}{{a:first-child}}
-\showCSSdemo{selector-001}{{a:last-child}}
-\showCSSdemo{selector-001}{{e:first-of-type}}
-\showCSSdemo{selector-001}{{gg d:only-of-type}}
-
-Instead of numbers you can also give the \type {an} and \type {an+b} formulas
-as well as the \type {odd} and \type {even} keywords:
-
-\showCSSdemo{selector-001}{{a:nth-child(even)}}
-\showCSSdemo{selector-001}{{a:nth-child(odd)}}
-\showCSSdemo{selector-001}{{a:nth-child(3n+1)}}
-\showCSSdemo{selector-001}{{a:nth-child(2n+3)}}
-
-There are a few special cases:
-
-\showCSSdemo{selector-001}{{g:empty}}
-\showCSSdemo{selector-001}{{g:root}}
-\showCSSdemo{selector-001}{{*}}
-
-Combining the \CSS\ methods with the regular ones is possible:
-
-\showCSSdemo{selector-001}{{g gg f .one}}
-\showCSSdemo{selector-001}{g/gg/f[@class='one']}
-\showCSSdemo{selector-001}{g/{gg f .one}}

-The next examples we use this file:
-
-\typebuffer[selector-002]
-
-\xmlloadbuffer{selector-002}{selector-002}
-
-When we filter from this (not too well structured) tree we can use both
-methods to achieve the same:
-
-\showCSSdemo{selector-002}{{document title .one, document title .three}}
-
-\showCSSdemo{selector-002}{/document/title[(@class='one') or (@class='three')]}
-
-However, imagine this file:
-
-\startbuffer[selector-003]
-<?xml version="1.0" ?>
-
-<document>
-    <title    class="one">title 1</title>
-    <subtitle class="sub">title 1.1</subtitle>
-    <title    class="two">title 2</title>
-    <subtitle class="sub">title 2.1</subtitle>
-    <title    class="one">title 3</title>
-    <subtitle class="sub">title 3.1</subtitle>
-    <title    class="two">title 4</title>
-    <subtitle class="sub">title 4.1</subtitle>
-</document>
-\stopbuffer
-
-\typebuffer[selector-003]
-
-\xmlloadbuffer{selector-003}{selector-003}
-
-The next filter in easier with the \CSS\ selector methods because these accumulate
-independent (simple) expressions:
-
-\showCSSdemo{selector-003}{{document title .one + subtitle, document title .two + subtitle}}
-
-Watch how we get an output in the document order. Because we render a sequential document
-a combined filter will trigger a sorting pass.

-\startsection[title={functions as filters}]
-
-At the \LUA\ end a whole \cmdinternal {cd:lpath} expression results in a (set of) node(s)
-with its environment, but that is hardly usable in \TEX. Think of code like:
-
-\starttyping
-for e in xml.collected(xml.load('text.xml'),"title") do
-  -- e = the element that matched
-end
-\stoptyping
-
-The older variant is still supported but you can best use the previous variant.
-
-\starttyping
-for r, d, k in xml.elements(xml.load('text.xml'),"title") do
-  -- r = root of the title element
-  -- d = data table
-  -- k = index in data table
-end
-\stoptyping
-
-Here \type {d[k]} points to the \type {title} element and in this case all titles
-in the tree pass by. In practice this kind of code is encapsulated in function
-calls, like those returning elements one by one, or returning the first or last
-match. The result is then fed back into \TEX, possibly after being altered by an
-associated setup. We've seen the wrappers to such functions already in a previous
-chapter.
-
-In addition to the previously discussed expressions, one can add so called
-filters to the expression, for instance:
-
-\starttyping
-a/(b|c)/!d/e/text()
-\stoptyping
-
-In a filter, the last part of the \cmdinternal {cd:lpath} expression is a
-function call. The previous example returns the text of each element \type {e}
-that results from matching the expression. When running \TEX\ the following
-functions are available. Some are also available when using pure \LUA. In \TEX\
-you can often use one of the macros like \type {\xmlfirst} instead of a \type
-{\xmlfilter} with finalizer \type {first()}. The filter can be somewhat faster
-but that is hardly noticeable.

-The extra arguments of the concatinators are: \type {separator} (string), \type

-can be added. Indeed this happens in some of the \XML\ related \MKIV\ modules,

-The number of commands is rather large and if you want to avoid them this is
-often possible. Take for instance:
-
-\starttyping
-\xmlall{#1}{/a/b[position()>3]}
-\stoptyping
-
-Alternatively you can use:
-
-\starttyping
-\xmlfilter{#1}{/a/b[position()>3]/all()}
-\stoptyping
-
-and actually this is also faster as internally it avoids a function call. Of
-course in practice this is hardly measurable.
-
-In previous examples we've already seen quite some expressions, and it might be
-good to point out that the syntax is modelled after \XSLT\ but is not quite the
-same. The reason is that we started with a rather minimal system and have already
-styles in use that depend on compatibility.
-
-\starttyping
-namespace:// axis node(set) [expr 1]..[expr n] / ... / filter
-\stoptyping
-
-When we are inside a \CONTEXT\ run, the namespace is \type {tex}. Hoewever, if
-you want not to print back to \TEX\ you need to be more explicit. Say that we
-typeset examns and have a (not that logical) structure like:
-
-\starttyping
-<question>
-  <text>...</text>
-  <answer>
-    <item>one</item>
-    <item>two</item>
-    <item>three</item>
-  </answer>
-  <alternative>
-    <condition>true</condition>
-    <score>1</score>
-  </alternative>
-  <alternative>
-    <condition>false</condition>
-    <score>0</score>
-  </alternative>
-  <alternative>
-    <condition>true</condition>
-    <score>2</score>
-  </alternative>
-</question>
-\stoptyping
-
-Say that we typeset the questions with:
-
-\starttyping
-\startxmlsetups question
-  \blank
-  score: \xmlfunction{#1}{totalscore}
-  \blank
-  \xmlfirst{#1}{text}
-  \startitemize
-      \xmlfilter{#1}{/answer/item/command(answer:item)}
-  \stopitemize
-  \endgraf
-  \blank
-\stopxmlsetups
-\stoptyping
-
-Each item in the answer results in a call to:
-
-\starttyping
-\startxmlsetups answer:item
-  \startitem
-    \xmlflush{#1}
-    \endgraf
-    \xmlfilter{#1}{../../alternative[position()=rootposition()]/
-      condition/command(answer:condition)}
-  \stopitem
-\stopxmlsetups
-\stoptyping
-
-\starttyping
-\startxmlsetups answer:condition
-  \endgraf
-  condition: \xmlflush{#1}
-  \endgraf
-\stopxmlsetups
-\stoptyping
-
-Now, there are two rather special filters here. The first one involves
-calculating the total score. As we look forward we use a function to deal with
-this.
-
-\starttyping
-\startluacode
-function xml.functions.totalscore(root)
-  local score = 0
-  for e in xml.collected(root,"/alternative") do
-    score = score + xml.filter(e,"xml:///score/number()") or 0
-  end
-  tex.write(score)
-end
-\stopluacode
-\stoptyping
-
-Watch how we use the namespace to keep the results at the \LUA\ end.
-
-The second special trick shown here is to limit a match using the current
-position of the root (\type {#}) match.
-
-As you can see, a path expression can be more than just filtering a few nodes. At
-the end of this manual you will find a bunch of examples.
-
-\stopsection
-
-\startsection[title={tables}]
-
-If you want to know how the internal \XML\ tables look you can print such a
-table:
-
-\starttyping
-print(table.serialize(e))
-\stoptyping
-
-This produces for instance:

-It can be hard to debug code as much happens kind of behind the screens.
-Therefore we have a couple of tracing options. Of course you can typeset some
-status information, using for instance:
-
-\startxmlcmd {\cmdbasicsetup{xmlshow}}
-    typeset the tree given by \cmdinternal {cd:node}
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlinfo}}
-    typeset the name in the element given by \cmdinternal {cd:node}
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlpath}}
-    returns the complete path (including namespace prefix and index) of the

-Say that we have the following \XML:
-
-\typebuffer[demo]
-
-and the next definitions:
-
-\startbuffer
-\startxmlsetups xml:demo:base
-    \xmlsetsetup{#1}{p|b}{xml:demo:*}
-\stopxmlsetups

-\startxmlsetups xml:demo:p

-\xmlregisterdocumentsetup{example-10}{xml:demo:base}
-
-\xmlprocessbuffer{example-10}{demo}{}
-\stopbuffer

-\typebuffer
-
-This will give us:
-
-\blank \startpacked \getbuffer \stoppacked \blank
-
-If you use \type {\xmlshow} you will get a complete subtree which can
-be handy for tracing but can also lead to large documents.
-
-We also have a bunch of trackers that can be enabled, like:
-
-\starttyping
-\enabletrackers[xml.show,xml.parse]

-In one of our workflows we produce books from \XML\ where the (educational)
-content is organized in many small files. Each book has about 5~chapters and each
-chapter is made of sections that contain text, exercises, resources, etc.\ and so
-the document is assembled from thousands of files (don't worry, runtime inclusion
-is pretty fast). In order to see where in the sources content resides we can
-trace the filename.
-
-\startxmlcmd {\cmdbasicsetup{xmlinclusion}}
-    returns the file where the node comes from
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlinclusions}}
-    returns the list of files where the node comes from
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlbadinclusions}}
-    returns a list of files that were not included due to some problem
-\stopxmlcmd
-
-Of course you have to make sure that these names end up somewhere visible, for
-instance in the margin.
-
-\stopsection
-
-\startsection[title={expansion}]
-
-For novice users the concept of expansion might sound frightening and to some
-extend it is. However, it is important enough to spend some words on it here.
-
-It is good to realize that most setups are sort of immediate. When one setup is
-issued, it can call another one and so on. Normally you won't notice that but
-there are cases where that can be a problem. In \TEX\ you can define a macro,
-take for instance:
-
-\starttyping
-\startxmlsetups xml:foo
-  \def\foobar{\xmlfirst{#1}{/bar}}
-\stopxmlsetups
-\stoptyping
-
-you store the reference top node \type {bar} in \type {\foobar} maybe for later use. In
-this case the content is not yet fetched, it will be done when \type {\foobar} is
-called.
-
-\starttyping
-\startxmlsetups xml:foo
-  \edef\foobar{\xmlfirst{#1}{/bar}}
-\stopxmlsetups
-\stoptyping
-
-Here the content of \type {bar} becomes the body of the macro. But what if
-\type {bar} itself contains elements that also contain elements. When there
-is a setup for \type {bar} it will be triggered and so on.
-
-When that setup looks like:
-
-\starttyping
-\startxmlsetups xml:bar
-  \def\barfoo{\xmlflush{#1}}
-\stopxmlsetups
-\stoptyping
-
-Here we get something like:
-
-\starttyping
-\foobar => {\def\barfoo{...}}
-\stoptyping
-
-When \type {\barfoo} is not defined we get an error and when it is known and expands
-to something weird we might also get an error.
-
-Especially when you don't know what content can show up, this can result in errors
-when an expansion fails, for example because some macro being used is not defined.
-To prevent this we can define a macro:
-
-\starttyping
-\starttexdefinition unexpanded xml:bar:macro #1
-  \def\barfoo{\xmlflush{#1}}
-\stoptexdefinition
-
-\startxmlsetups xml:bar
-  \texdefinition{xml:bar:macro}{#1}
-\stopxmlsetups
-\stoptyping
-
-The setup \type {xml:bar} will still expand but the replacement text now is just the
-call to the macro, think of:
-
-\starttyping
-\foobar => {\texdefinition{xml:bar:macro}{#1}}
-\stoptyping
-
-But this is often not needed, most \CONTEXT\ commands can handle the expansions
-quite well but it's good to know that there is a way out. So, now to some
-examples. Imagine that we have an \XML\ file that looks as follows:
-
-\starttyping
-<?xml version='1.0' ?>
-<demo>
-    <chapter>
-        <title>Some <em>short</em> title</title>
-        <content>
-            zeta
-            <index>
-                <key>zeta</key>
-                <content>zeta again</content>
-            </index>
-            alpha
-            <index>
-                <key>alpha</key>
-                <content>alpha <em>again</em></content>

-            gamma
-            <index>

-                <content>delta</content>
-            </index>
-            done!

-There are a few structure related elements here: a chapter (with its list entry)
-and some index entries. Both are multipass related and therefore travel around.
-This means that when we let data end up in the auxiliary file, we need to make
-sure that we end up with either expanded data (i.e.\ no references to the \XML\
-tree) or with robust forward and backward references to elements in the tree.
-
-Here we discuss three approaches (and more may show up later): pushing \XML\ into
-the auxiliary file and using references to elements either or not with an
-associated setup. We control the variants with a switch.
-
-\starttyping
-\newcount\TestMode
-
-\TestMode=0 % expansion=xml
-\TestMode=1 % expansion=yes, index, setup
-\TestMode=2 % expansion=yes
-\stoptyping
-
-We apply a couple of setups:
-
-\starttyping
-\startxmlsetups xml:mysetups
-    \xmlsetsetup{\xmldocument}{demo|index|content|chapter|title|em}{xml:*}
-\stopxmlsetups
-
-\xmlregistersetup{xml:mysetups}
-\stoptyping
-
-The main document is processed with:
-
-\starttyping
-\startxmlsetups xml:demo
-    \xmlflush{#1}
-    \subject{contents}
-    \placelist[chapter][criterium=all]
-    \subject{index}
-    \placeregister[index][criterium=all]
-    \page % else buffer is forgotten when placing header
-\stopxmlsetups
-\stoptyping
-
-First we show three alternative ways to deal with the chapter. The first case
-expands the \XML\ reference so that we have an \XML\ stream in the auxiliary
-file. This stream is processed as a small independent subfile when needed. The
-second case registers a reference to the current element (\type {#1}). This means
-that we have access to all data of this element, like attributes, title and
-content. What happens depends on the given setup. The third variant does the same
-but here the setup is part of the reference.
-
-\starttyping
-\startxmlsetups xml:chapter
-    \ifcase \TestMode
-        % xml code travels around
-        \setuphead[chapter][expansion=xml]
-        \startchapter[title=eh: \xmltext{#1}{title}]
-            \xmlfirst{#1}{content}
-        \stopchapter
-    \or
-        % index is used for access via setup
-        \setuphead[chapter][expansion=yes,xmlsetup=xml:title:flush]
-        \startchapter[title=\xmlgetindex{#1}]
-            \xmlfirst{#1}{content}
-        \stopchapter
-    \or
-        % tex call to xml using index is used
-        \setuphead[chapter][expansion=yes]
-        \startchapter[title=hm: \xmlreference{#1}{xml:title:flush}]
-            \xmlfirst{#1}{content}
-        \stopchapter
-    \fi
-\stopxmlsetups
-
-\startxmlsetups xml:title:flush
-    \xmltext{#1}{title}
-\stopxmlsetups
-\stoptyping
-
-We need to deal with emphasis and the content of the chapter.
-
-\starttyping
-\startxmlsetups xml:em
-    \begingroup\em\xmlflush{#1}\endgroup
-\stopxmlsetups
-
-\startxmlsetups xml:content
-    \xmlflush{#1}
-\stopxmlsetups
-\stoptyping
-
-A similar approach is followed with the index entries. Watch how we use the
-numbered entries variant (in this case we could also have used just \type
-{entries} and \type {keys}).
-
-\starttyping
-\startxmlsetups xml:index
-    \ifcase \TestMode
-        \setupregister[index][expansion=xml,xmlsetup=]
-        \setstructurepageregister
-          [index]
-          [entries:1=\xmlfirst{#1}{content},
-           keys:1=\xmltext{#1}{key}]
-    \or
-        \setupregister[index][expansion=yes,xmlsetup=xml:index:flush]
-        \setstructurepageregister
-          [index]
-          [entries:1=\xmlgetindex{#1},
-           keys:1=\xmltext{#1}{key}]
-    \or
-        \setupregister[index][expansion=yes,xmlsetup=]
-        \setstructurepageregister
-          [index]
-          [entries:1=\xmlreference{#1}{xml:index:flush},
-           keys:1=\xmltext{#1}{key}]
-    \fi
-\stopxmlsetups
-
-\startxmlsetups xml:index:flush
-    \xmlfirst{#1}{content}
-\stopxmlsetups
-\stoptyping
-
-Instead of this flush, you can use the predefined setup \type {xml:flush}
-unless it is overloaded by you.
-
-The file is processed by:
-
-\starttyping
-\starttext
-    \xmlprocessfile{main}{test.xml}{}
-\stoptext
-\stoptyping
-
-We don't show the result here. If you're curious what the output is, you can test
-it yourself. In that case it also makes sense to peek into the \type {test.tuc}
-file to see how the information travels around. The \type {metadata} fields carry
-information about how to process the data.
-
-The first case, the \XML\ expansion one, is somewhat special in the sense that
-internally we use small pseudo files. You can control the rendering by tweaking
-the following setups:
-
-\starttyping
-\startxmlsetups xml:ctx:sectionentry
-    \xmlflush{#1}
-\stopxmlsetups
-
-\startxmlsetups xml:ctx:registerentry
-    \xmlflush{#1}
-\stopxmlsetups
-\stoptyping
-
-{\em When these methods work out okay the other structural elements will be
-dealt with in a similar way.}
-
-\stopsection
-
-\startsection[title={special cases}]
-
-Normally the content will be flushed under a special (so called) catcode regime.
-This means that characters that have a special meaning in \TEX\ will have no such
-meaning in an \XML\ file. If you want content to be treated as \TEX\ code, you can
-use one of the following:
-
-\startxmlcmd {\cmdbasicsetup{xmlflushcontext}}
-    flush the given \cmdinternal {cd:node} using the \TEX\ character
-    interpretation scheme
-\stopxmlcmd
-
-\startxmlcmd {\cmdbasicsetup{xmlcontext}}
-    flush the match of \cmdinternal {cd:lpath} for the given \cmdinternal
-    {cd:node} using the \TEX\ character interpretation scheme
-\stopxmlcmd
-
-We use this in cases like:
-
-\starttyping
-....
-  \xmlsetsetup {#1} {
-      tm|texformula|
-  } {xml:*}
-....
-
-\startxmlsetups xml:tm
-  \mathematics{\xmlflushcontext{#1}}
-\stopxmlsetups
-
-\startxmlsetups xml:texformula
-  \placeformula\startformula\xmlflushcontext{#1}\stopformula
-\stopxmlsetups
-\stoptyping
-
-\stopsection
-
-\startsection[title={collecting}]
-
-Say that your document has
-
-\starttyping
-<table>
-    <tr>
-        <td>foo</td>
-        <td>bar<td>
-    </tr>
-</table>
-\stoptyping
-
-And that you need to convert that to \TEX\ speak like:
-
-\starttyping
-\bTABLE
-    \bTR
-        \bTD foo \eTD
-        \bTD bar \eTD
-    \eTR
-\eTABLE
-\stoptyping
-
-A simple mapping is:
-
-\starttyping
-\startxmlsetups xml:table
-    \bTABLE \xmlflush{#1} \eTABLE
-\stopxmlsetups
-\startxmlsetups xml:tr
-    \bTR \xmlflush{#1} \eTR
-\stopxmlsetups
-\startxmlsetups xml:td
-    \bTD \xmlflush{#1} \eTD
-\stopxmlsetups
-\stoptyping
-
-The \type {\bTD} command is a so called delimited command which means that it
-picks up its argument by looking for an \type {\eTD}. For the simple case here
-this works quite well because the flush is inside the pair. This is not the case
-in the following variant:
-
-\starttyping
-\startxmlsetups xml:td:start
-    \bTD
-\stopxmlsetups
-\startxmlsetups xml:td:stop
-    \eTD
-\stopxmlsetups
-\startxmlsetups xml:td
-    \xmlsetup{#1}{xml:td:start}
-    \xmlflush{#1}
-    \xmlsetup{#1}{xml:td:stop}
-\stopxmlsetups
-\stoptyping
-
-When for some reason \TEX\ gets confused you can revert to a mechanism that
-collects content.
-
-\starttyping
-\startxmlsetups xml:td:start
-    \startcollect
-        \bTD
-    \stopcollect
-\stopxmlsetups
-\startxmlsetups xml:td:stop
-    \startcollect
-        \eTD
-    \stopcollect
-\stopxmlsetups
-\startxmlsetups xml:td
-    \startcollecting
-        \xmlsetup{#1}{xml:td:start}
-        \xmlflush{#1}
-        \xmlsetup{#1}{xml:td:stop}
-    \stopcollecting
-\stopxmlsetups
-\stoptyping
-
-You can even implement solutions that effectively do this:
-
-\starttyping
-\startcollecting
-    \startcollect \bTABLE \stopcollect
-        \startcollect \bTR \stopcollect
-            \startcollect \bTD \stopcollect
-            \startcollect   foo\stopcollect
-            \startcollect \eTD \stopcollect

-            \startcollect   bar\stopcollect

-        \startcollect \eTR \stopcollect
-    \startcollect \eTABLE \stopcollect
-\stopcollecting
-\stoptyping
-
-Of course you only need to go that complex when the situation demands it. Here is
-another weird one:
-
-\starttyping
-\startcollecting
-    \startcollect \setupsomething[\stopcollect
-        \startcollect foo=\stopcollect

-There is not that much system in the following examples. They resulted from tests
-with different documents. The current implementation evolved out of the
-experimental code. For instance, I decided to add the multiple expressions in row
-handling after a few email exchanges with Jean|-|Michel Huffen.
-
-One of the main differences between the way \XSLT\ resolves a path and our way is
-the anchor. Take:
-
-\starttyping
-/something
-something
-\stoptyping
-
-The first one anchors in the current (!) element so it will only consider direct
-children. The second one does a deep lookup and looks at the descendants as well.
-Furthermore we have a few extra shortcuts like \type {**} in \type {a/**/b} which
-represents all descendants.
-
-The expressions (between square brackets) has to be valid \LUA\ and some
-preprocessing is done to resolve the built in functions. So, you might use code
-like:
-
-\starttyping
-my_lpeg_expression:match(text()) == "whatever"
-\stoptyping
-
-given that \type {my_lpeg_expression} is known. In the examples below we use the
-visualizer to show the steps. Some are shown more than once as part of a set.

-There is also \type {last-match::} that starts with the last found set of nodes.
-This can save some run time when you do lots of tests combined with a same check
-afterwards. There is however one pitfall: you never know what is done with that
-last match in the setup that gets called nested. Take the following example:
-
-\starttyping
-\startbuffer[test]
-<something>
-    <crap> <crapa> <crapb> <crapc> <crapd>
-        <crape>
-            done 1
-        </crape>
-    </crapd>  </crapc> </crapb>  </crapa>
-    <crap> <crapa> <crapb> <crapc> <crapd>
-        <crape>
-            done 2
-        </crape>
-    </crapd>  </crapc> </crapb>  </crapa>
-    <crap> <crapa> <crapb> <crapc> <crapd>
-        <crape>
-            done 3
-        </crape>
-    </crapd>  </crapc> </crapb>  </crapa>
-</something>
-\stopbuffer
-\stoptyping
-
-One way to filter the content is this:
-
-\starttyping
-\xmldoif {#1} {/crap/crapa/crapb/crapc/crapd/crape} {
-    some action
-}
-\stoptyping
-
-It is not unlikely that you will do something like this:
-
-\starttyping
-\xmlfirst {#1} {/crap/crapa/crapb/crapc/crapd/crape} {
-    \xmlfirst{#1}{/crap/crapa/crapb/crapc/crapd/crape}
-}
-\stoptyping
-
-This means that the path is resolved twice but that can be avoided as
-follows:
-
-\starttyping
-\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
-    \xmlfirst{#1}{last-match::}
-}
-\stoptyping
-
-But the next is now guaranteed to work:
-
-\starttyping
-\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
-    \xmlfirst{#1}{last-match::}
-    \xmllast{#1}{last-match::}
-}
-\stoptyping
-
-Because the first one can have done some lookup the last match can be replaced
-and the second call will give unexpected results. You can overcome this with:
-
-\starttyping
-\xmldoif{#1}{/crap/crapa/crapb/crapc/crapd/crape}{
-    \xmlpushmatch
-    \xmlfirst{#1}{last-match::}
-    \xmlpopmatch
-}
-\stoptyping
-
-Does it pay off? Here are some timings of a 10.000 times text and lookup
-like the previous (on a decent Januari 2016 laptop):
-
-\starttabulate[|r|l|]
-\NC 0.239 \NC \type {\xmldoif {...} {...}}                                     \NC \NR
-\NC 0.292 \NC \type {\xmlfirst {...} {...}}                                    \NC \NR
-\NC 0.538 \NC \type {\xmldoif {...} {...} + \xmlfirst {...} {...}}             \NC \NR
-\NC 0.338 \NC \type {\xmldoif {...} {...} + \xmlfirst {...} {last-match::}}    \NC \NR
-\NC 0.349 \NC \type {+ \xmldoif {...} {...} + \xmlfirst {...} {last-match::}-} \NC \NR
-\stoptabulate
-
-So, pushing and popping (the last row) is a bit slower than not doing that but it
-is still much faster than not using \type {last-match::} at all. As a shortcut
-you can use \type {=}, as in:
-
-\starttyping
-\xmlfirst{#1}{=}
-\stoptyping
-
-You can even do this:
-
-\starttyping
-\xmlall{#1}{last-match::/text()}
-\stoptyping
-
-or
-
-\starttyping
-\xmlall{#1}{=/text()}

-\startsection[title=attribute chains]
-
-In \CSS, when an attribute is not present, the parent element is checked, and when
-not found again, the lookup follows the chain till a match is found or the root is
-reached. The following example demonstrates how such a chain lookup works.
-
-\startbuffer[test]
-<something mine="1" test="one" more="alpha">
-  <whatever mine="2" test="two">
-    <whocares mine="3">
-      <!-- this is a test -->

-\stoptyping
-
-Here we first determine if there is a child \type {what} with attribute \type {a}
-set to \type {1}. Depending on the outcome again we check the child nodes for

-A rather common way to add cross references to \XML\ files is to borrow the

-context.tocontext(t)

-One might wonder how a \TEX\ macro package would look like when backslashes,
-dollars and percent signs would have no special meaning. In fact, it would be
-rather useless as interpreting commands are triggered by such characters. Any
-formatting or coding system needs such characters. Take \XML: angle brackets and
-ampersands are really special. So, no matter what system we use, we do have to
-deal with the (common) case where these characters need to be sees as they are.
-Normally escaping is the solution.
-
-The \CONTEXT\ interface for \XML\ suffers from this as well. You really don't
-want to know how many tricks are used for dealing with special characters and
-entities: there are several ways these travel through the system and it is
-possible to adapt and cheat. Especially roundtripped data (via tuc file) puts
-some demands on the system because when ts \XML\ can become \TEX\ and vise versa.

+%D This is a rather old mechanism that we once needed in an actually nice
+%D design. Those were the times that processing a rather complex xml file
+%D with pdftex  into a 400 page document took 45 minutes (a few runs) while
+%D nowadays with luatex and mkiv we express runtime in seconds.
+%D
+%D The logic is mostly the same but some work is delegated to Lua so that
+%D we save memory and also run faster. As this was not really a used module
+%D the interface also was upgraded. As we know the bottlenecks in mp we also
+%D work around it a bit.

 %D have bad side effects.
 
+%D For the moment we put these here as they are pdf related but they might move to

+-- This is a rather special test-only feature that I added for the sake of testing
+-- Idris's husayni. We wanted to know if uniscribe obeys the order of lookups in a
+-- font, in spite of what the description of handling arabic suggests. And indeed,
+-- mixed-in lookups of other features (like all these ss* in husayni) are handled
+-- the same in context as in uniscribe. If one sets reorderlookups=arab then we sort
+-- according to the "assumed" order so e.g. the ss* move to after the standard
+-- features. The observed difference in rendering is an indication that uniscribe is
+-- quite faithful to the font (while e.g. tests with the hb plugin demonstrate some
+-- interference, apart from some hard coded init etc expectations). Anyway, it means
+-- that we're okay with the (generic) node processor. A pitfall is that in context
+-- we can actually control more, so we can trigger an analyze pass with e.g.
+-- dflt/dflt while the libraries depend on the script settings for that. Uniscribe
+-- probably also parses the string and when seeing arabic will follow a different
+-- code path, although it seems to treat all features equal.

+
+%D In \LUATEX\ we provide the socket library that is more or less the standard one
+%D for \LUA. It has been around for a while and seems to be pretty stable. The
+%D binary module is copmpiled into \LUATEX\ and the accompanying .lua files are
+%D preloaded. These files are mostly written by Diego Nehab, Andre Carregal, Javier
+%D Guerra, and Fabio Mascarenhas with contributions from Diego Nehab, Mike Pall,
+%D David Burgess, Leonardo Godinho, Thomas Harning Jr., and Gary NG. The originals
+%D are part of and copyrighted by the Kepler project.
+%D
+%D Here we reload a slightly reworked version of these \type {.lua} files. We keep
+%D the same (documented) interface but streamlined some fo the code. No more
+%D modules, no more pre 5.2 \LUA, etc. Also, as it loads into the \CONTEXT
+%D ecosystem, we plug in some logging. (and maybe tracing in the future). As we
+%D don't support serial ports in \LUATEX, related code has been dropped.
+%D
+%D The files are reformatted so that we can more easilly add additional features
+%D and|/|or tracing options. Any error introduced there is our fault! The url module
+%D might be replaced by the one in \CONTEXT. When we need mbox a suitable variant
+%D will be provided.
+
+%D Currently we preload the related \LUA\ code in \LUATEX, but that might change at
+%D some point. We're prepared for that.

+%D     The fraction of fossil olfactory receptor genes is significantly higher in
+%D     all species with full color vision. This suggests that the evolution of
+%D     trichromatic vision --- which allows these primates to detect food, mates,
+%D     and danger with visual cues --- has reduced their reliance on the sense of

+In LuaTeX we provide the socket library that is more or less the standard one for
+Lua. It has been around for a while and seems to be pretty stable. The binary
+module is copmpiled into LuaTeX and the accompanying .lua files are preloaded.
+These files are mostly written by Diego Nehab, Andre Carregal, Javier Guerra, and
+Fabio Mascarenhas with contributions from Diego Nehab, Mike Pall, David Burgess,
+Leonardo Godinho, Thomas Harning Jr., and Gary NG. The originals are part of and
+copyrighted by the Kepler project.
+
+Here we reload a slightly reworked version of these .lua files. We keep the same
+(documented) interface but streamlined some fo the code. No more modules, no more
+pre 5.2 Lua, etc. Also, as it loads into the ConTeXt ecosystem, we plug in some
+logging. (and maybe tracing in the future). As we don't support serial ports in
+LuaTeX, related code has been dropped.
+
+The files are reformatted so that we can more easilly add additional features
+and/or tracing options. Any error introduced there is our fault! The url module
+might be replaced by the one in ConTeXt. When we need mbox a suitable variant
+will be provided.

+%D The original document dates from 2000 and was meant for a presentation at \TUG\
+%D 2001. It used widgets and in particular check fields and push buttons.
+%D \JAVASCRIPT\ was used to show or hide them when rolling over, and appearances
+%D changed in a subtle way. It actually worked quite well at that time.
+%D
+%D However, over time these widgets proved to be sort of unstable. For instance we
+%D used the parent|-|child model of which (inheritance and appearance) behaviour
+%D changed over time. We're talking of a few decades ago when \TEX\ was one of the
+%D few (maybe only) tools that could actually support everything that the manual
+%D introduced: the \quote {standard} seemed to be ahead of the viewer. Anyway, we
+%D adapted but it meant that old document in principle were not always future proof.
+%D
+%D We used in this document a push button in the background of the menu so that it
+%D could become visible when rolled over. There were no layers in \PDF\ at that
+%D time! Nowadays such a trick doesn't work well because of the way a viewer
+%D intercepts regions. One gets kind of erratic behaviour when applying \JAVASCRIPT.
+%D
+%D I spent quite some time to test if we could still do the same without side
+%D effects and in the process also noticed that some functionality in \JAVASCRIPT\
+%D seems broken (or changed due to maybe security issues). So, in the end I decided
+%D to simplify the approach and use layers to pop up the menu when the mouse goes
+%D over it but no longer hide it when the mouse leaves that area. It just doesn't
+%D work too well otherwise.
+
+%D We start with the layout. We basically have three areas: edge, margin and text.
+%D Each are more or less the same width.

+%D The bodyfont is the Latin Modern Variable (of course at that time we used
+%D the Computer Modern predecessors). We still apply protrusion and expansion.
+%D The new \quotation {Modern Latin} look also works ok on screen.

+% Principles of the Bulgarian hyphenation
+% =======================================
+% 
+% One specificity of the Bulgarian language is that the average length
+% of the words is greater than in English.  When typesetting a Bulgarian
+% text, hyphenation is more important than when typesetting an English
+% text.  Knuth's algorithm for line-breaking is such that in most
+% English paragraphs no hyphenation will be used.  With a Bulgarian
+% text, however, even the Knuth's algorithm will use hyphenation in most
+% paragraphs.  Hyphenation becomes an absolute necessity if we want to
+% obtain nice, justified paragraphs when using a software with dumb
+% line-breaking algorithm, such as LibreOffice.
+% 
+% According to Decree 936 of the Council of Ministers promulgated on 27
+% November 1950, the Institute for Bulgarian Language at the Bulgarian
+% Academy of Sciences is authorised to publish the rules of the
+% orthography of the Bulgarian language (within certain limits).
+% 
+% Hyphenation rules between 1945 and 1983
+% ---------------------------------------
+% 
+% Between 1945 and 1983 Bulgarian used syllable hyphenation with two
+% morphological exceptions: hyphenation is preferred between a prefix
+% and a stem and at the boundary of compound words.  The following were
+% the rules governing the hyphenation:
+% 
+% 1. One letter does not stay alone.  Words of one syllable can not be
+%    hyphenated.
+% 2. No hyphenation before or after ь.
+% 3. In a sequence of vowels at least one vowel stays before the
+%    hyphen.
+% 4. A single consonant between two vowels links with the second vowel.
+%    For example по-ле /po-le/, ра-бо-та /ra-bo-ta/.
+% 5. In a sequence of consonants between two vowels, at least one
+%    consonant stays with the second vowel.  For example те-сто /te-sto/
+%    or тес-то /tes-to/.[^b]
+% 6. In a sequence of consonants between two vowels, if the first
+%    consonant is sonorant (й /y/, л /l/, м /m/, н /n/, р /r/), then it
+%    stays with the first vowel.  For example гер-дан /ger-dan/, сен-ки
+%    /sen-ki/.
+% 7. The hyphenation separates two successive equal consonants. For
+%    example времен-но /vremen-no/, пролет-та /prolet-ta/.
+% 8. When the letters дж /dzh/ and дз /dz/ denote a single consonant,
+%    then they are not separated.  For example боя-джия /boya-dzhiya/
+%    but not бояд-жия /boyad-zhiya/.  When these letters denote two
+%    consonants, then the normal rules apply: над-живявам
+%    /nad-zhivyavam/.
+% 9. Word prefixes may not be broken.  Compound words are hyphenated
+%    either at the boundary of the components or the hyphenation rules
+%    are applied to each of the components separately.  For example:
+%    пред-упреждавам /pred-uprezhdavam/ (not пре-дупреждавам
+%    /pre-duprezhdavam/), пред-известие /pred-izvestie/ (not
+%    пре-дизвестие /pre-dizvestie/), за-движвам /za-dvizhvam/ (not
+%    зад-вижвам /zad-vizhvam/), авто-клуб /avto-klub/ (not авток-луб
+%    /avtok-lub/), вакуум-апарат /vakuum-aparat/ (not вакуу-мапарат
+%    /vakuu-maparat/).
+% 
+% In some rare cases the proper application of rule 9 depends on the
+% semantics of the word.  For example пре-дреша /pre-dresha/ 'change
+% clothes' but пред-реша /pred-resha/ 'predetermine' or прес-пите
+% /pres-pite/ 'the snow-drifts' but пре-спите /pre-spite/ 'sleep for a
+% while/overnight'.
+% 
+% [^b]: In several publications this rule is formulated with the
+%     additional restriction that the sequence of consonants begins with
+%     an obstruent.  I believe this restriction is unintentional.  It
+%     makes no sense to forbid a hyphenation of the form AB-A but to
+%     permit ABB-A (A denotes a vowel and B – a consonant).
+% 
+% Hyphenation rules between 1983 and 2012
+% ---------------------------------------
+% 
+% The Orthographic dictionary published by the Institute for Bulgarian
+% language in 1983 introduced new hyphenation rules.  The complexity of
+% the previous rules was the main reason for the change.  The new rules
+% aimed at two objectives: simplicity and unambiguity.
+% 
+% The new rules are:
+% 
+% 1. A consonant between two vowels links with the second vowel.  For
+%    example ви-со-чи-на /vi-so-chi-na/.
+% 2. In a sequence of two or more consonants between two vowels, at
+%    least one consonant stays with first vowel and at least one with
+%    the second vowel.  For example сес-тра /ses-tra/ and сест-ра
+%    /sest-ra/.
+% 3. Two equal consonants are separated.  For example плен-ник
+%    /plen-nik/.
+% 4. In a sequence of two or more vowels, the first vowel stays before
+%    the hyphen.  For example пре-одолея /pre-odoleya/ and прео-долея
+%    /preo-doleya/.
+% 5. In a sequence of three or more vowels, the last vowel stays after
+%    the hyphen.  For example мао-изъм /mao-izam/ but not маои-зъм
+%    /maoi-zam/.
+% 6. The letter й /y/ between a vowel and a consonant stays with the
+%    vowel.  For example май-ка /may-ka/.
+% 7. When a sequence of two or more consonants follows й /y/ then at
+%    least one consonant links with й /y/.  For example айс-берг
+%    /ays-berg/ (not ай-сберг /ay-sberg/).
+% 8. The letter й /y/ between two vowels links with the second vowel.
+%    For example ма-йор /ma-yor/.
+% 9. No hyphenation before or after ь.
+% 10. When the letters дж /dzh/ denote a single consonant, then they are
+%     not separated.  For example су-джук /su-dzhuk/ (not суд-жук
+%     /sud-zhuk/) but над-живея /nad-zhiveya/.
+% 11. There must be at least one vowel before and after the hyphen.
+% 12. One letter does not stay alone.
+% 
+% The total disregard of the morphology by these rules leads to some
+% strange results.  For example пре-дизвестие /pre-dizvestie/ is
+% permitted and пред-известие /pred-izvestie/ is forbidden, зад-вижвам
+% /zad-vizhvam/ is permitted and за-движвам /za-dvizhvam/ is forbidden,
+% авток-луб /avtok-lub/ is permitted and авто-клуб /avto-klub/ is
+% forbidden, вакуу-мапарат /vakuu-maparat/ is permitted and
+% вакуум-апарат /vakuum-aparat/ is forbidden.  Because of this, the new
+% rules were not universally accepted.  The old rules are still
+% mentioned in various places in Internet, they are included even in
+% some grammar books published by the publishing houses of the Ministry
+% of Education and of Sofia University.  The software developers,
+% however, soon came into love with the new hyphenation rules.
+% 
+% Hyphenation rules after 2012
+% ----------------------------
+% 
+% In 2012 new rules came into force.  There are two differences with
+% respect to the previous rules:
+% 
+% 1. Rule 5 of the previous rules is revoked.  For example маои-зъм
+%    /maoi-zam/ becomes a valid hyphenation.
+% 2. The new rules permit morphologically based hyphenation (however it
+%    is not obligatory).  For example пред-известие /pred-izvestie/,
+%    за-движвам /za-dvizhvam/, авто-клуб /avto-klub/, вакуум-апарат
+%    /vakuum-aparat/ are valid hyphenations.
+% 
+% Good hyphenation is a complex matter and it seems the linguists at the
+% Institute for Bulgarian Language have recognised this.  They no longer
+% attempt to provide universal rules about everything.  Instead, they
+% provide some very permissible rules while the good application of
+% these rules is leaved to the discretion and the experience of the
+% printers and the developers of hyphenation software.
+% 
+% It makes sense to use at least two different sets of hyphenation rules
+% for Bulgarian.  In most cases a more restrictive version should be
+% used, one which attempts to eliminate the controversial cases of
+% hyphenation.  When typesetting a Bulgarian text in a narrow newspaper
+% column, however, it will be appropriate to use more liberal
+% hyphenation rules.  It should be noted that one of the reasons for the
+% hyphenation reform in 1983 was the desire to fix the chaotic
+% hyphenation in the Bulgarian newspapers at that time.
+% 
+% Computer implementations
+% ========================
+% 
+% Mathematical analysis of the Bulgarian hyphenation
+% --------------------------------------------------
+% 
+% The earliest mathematical analysis of the Bulgarian hyphenation rules
+% belongs to Veska Noncheva.[^1] In 1988 she proposed a mathematical
+% formalisation of the hyphenation rules in a table with 22 rows.[^2]
+% 
+% [^1]: <http://www.researchgate.net/profile/Veska_Noncheva>
+% 
+% [^2]: Нончева В. Алгоритъм за автоматично пренасяне на думи в
+%     българския език. Математика и математическо
+%     образование. Сб. доклади на 17. ПК на СМБ. С., БАН, 1988, 479-482.
+% 
+% In the same year Eugene Belogay[^3] proposed an alternative
+% formalisation with only 9 rules.[^4] Belogay proved that his rules are
+% consistent and that they form a minimal set.  The rules of Belogay
+% have negative character – every hyphenation which is not forbidden by
+% a rule is possible hyphenation.
+% 
+% [^3]: <http://www.linkedin.com/in/belogay>
+% 
+% [^4]: Белогай Е. Алгоритъм за автоматично пренасяне на думи. Компютър
+%     за вас (1988) 3, 12-14.
+% 
+% The following are the first 7 rules, as formulated by Belogay:
+% 
+% 1. Б-А
+% 2. А-ББ
+% 3. Б-ТТ, ТТ-Б
+% 4. ААА-Б
+% 5. й-ББ
+% 6. Б-ь
+% 7. д-ж
+% 
+% Here А denotes an arbitrary vowel letter, Б denotes an arbitrary
+% consonant letter (including ь and й), ТТ denotes a sequence of two
+% equal consonant letters and the letters й, ь, д and ж denote
+% themselves.  For example the rule "Б-А" says that we are not permitted
+% to separate a consonant letter from immediately following vowel
+% letter.
+% 
+% The eighth rule of Belogay says that hyphenation is forbidden before
+% the first and after the last vowel letter.  The ninth rule of Belogay
+% says that hyphenation is forbidden immediately after the first or
+% immediately before the last letter of the word.
+% 
+% Notice that is is very easy to translate the rules of Belogay in the
+% form, required for the hyphenation algorithm of Knuth and Liang used
+% in TeX.[^a] Let us remind that this algorithm matches the word with a
+% set of string patterns in which the odd numbers say hyphenation is
+% permitted in this position and even numbers say the hyphenation is
+% forbidden.  When two patterns give conflicting numbers for the same
+% position, then the greater number wins.
+% 
+% First, since the rules of Belogay are negative (they say where
+% hyphenation is forbidden, not where it is permitted), we have to
+% permit the hyphenation everywhere:
+% 
+% 1. А1
+% 2. Б1
+% 
+% Then, the first seven rules of Belogay obtain the form:
+% 
+% 1. Б2А
+% 2. А2ББ
+% 3. Б2ТТ ТТ2Б
+% 4. ААА2Б
+% 5. й2ББ
+% 6. Б2ь
+% 7. д2ж
+% 
+% Since no Bulgarian word starts with more that four consonants and no
+% Bulgarian word ends with more than three consonants, the eighth rule
+% of Belogay can be translated in the following way:
+% 
+% 1. .Б2
+% 2. .ББ2
+% 3. .БББ2
+% 4. 2Б.
+% 5. 2ББ.
+% 
+% The ninth rule of Belogay means that left and right hyphen mins should
+% be set to 2.
+% 
+% The work of Eugene Belogay was not limited to merely a mathematical
+% analysis of the Bulgarian hyphenation rules.  In his paper he
+% published a short algorithm in Pascal which implements these rules.
+% It didn't take long for this algorithm to be used in various text
+% processing software.  The algorithm of Belogay was famous for many
+% years.  Even as late as 1997 in one book about TeX, the author didn't
+% care to give any explanations but simply wrote about "the algorithm of
+% Belogay" as something well known to the reader.[^5]

+% 
+% Bulgarian hyphenation in TeX
+% ----------------------------
+% 
+% One unfortunate design decision of Knuth was that the hyphenation
+% algorithm of TeX applied the hyphenation patterns not to the input
+% character codes but to the internal codes of the glyphs in the font.
+% This created a problem for the Cyrillic languages because in TeX the
+% Cyrillic fonts did not have standardised encoding.  Perhaps this is
+% one of the reasons why the earliest implementations of the Bulgarian
+% hyphenation in TeX did not rely on the internal hyphenation algorithm
+% of TeX.  Instead, external tools were used to insert soft hyphens in
+% all Bulgarian words.  For example such a tool would replace the word
+% сричкопренасяне /srichkoprenasyane/ with
+% срич\\-коп\\-ре\\-на\\-ся\\-не /srich\\-kop\\-re\\-na\\-sya\\-ne/.
+% The saying "To every disadvantage there is a corresponding advantage"
+% is true – since Cyrillic and Latin letters use different character
+% codes, an external tool could easily insert soft hyphens in all
+% Bulgarian words while leaving the TeX commands intact.
+% 
+% The earliest known attempt to use the hyphenation algorithm of TeX for
+% Bulgarian was made by Ognyan Tonev in 1990.[^6] He described his work
+% as "a not very good translation of the rules.  I work in this
+% direction.  But I don't have a 100% working complect of patterns.  So,
+% the copy I send to you[^7] is only a beta-version."  The hyphenation
+% patterns of Tonev don't work correctly and it seems he never completed
+% his work.
+% 
+% [^6]: The author of this text was unable to find current information
+%     about Ognyan Tonev in Internet.  Apparently in 1990 he worked in
+%     the Center of Informatics and Computer Technology of the Bulgarian
+%     Academy of Sciences.
+% 
+% [^7]: To Yannis Haralambous,
+%     <http://perso.telecom-bretagne.eu/yannisharalambous>
+% 
+% The first usable Bulgarian hyphenation patterns for TeX were developed
+% by Georgi Boshnakov[^8] in 1994.  In order to solve the encoding
+% problem, Boshnakov had developed TeX fonts supporting the MIK encoding
+% (the prevalent encoding at that time in Bulgaria).  This allowed him
+% to introduce a fully working implementation only a few months after
+% LaTeX2e became the official LaTeX version.  Later Boshnakov modified
+% his work with the Babel system.  The hyphenation patterns of Boshnakov
+% did their job well enough, so that for almost quarter a century after
+% their initial creation, they remained the only Bulgarian hyphenation
+% patterns in the standard distributions of TeX and CTAN.
+% 
+% [^8]: <http://www.maths.manchester.ac.uk/~gb/>
+% 
+% There are some similarities between the patterns of Boshnakov and the
+% patterns of Belogay.  The following are the main differences.
+% 
+% First, Boshnakov used an ingenious and more compact implementation of
+% the second and the third rule.  Instead of {А2ББ, Б2ТТ, ТТ2Б}, or
+% 8×22×22+22×22+22×22=4840 patterns in total, Boshnakov has patterns of
+% the form 2Б3Б2 and 4Т3Т4, or only 22×22=484 in total, with the same
+% effect.
+% 
+% The second main difference between the patterns of Boshnakov and the
+% patterns of Belogay concerns the letter combination дж /dzh/.  In
+% Bulgarian this letter combination can denote either a single
+% consonant, or a sequence of two consonants and the hyphenation rules
+% change respectively.  Unfortunately, it is impossible to know the
+% meaning of дж /dzh/ without a vocabulary.  The solution of Belogay was
+% a cautious one – his rules do the hyphenation in a way which will be
+% correct regardless of whether дж /dzh/ is a single consonant or a
+% sequence of two consonant.  On the other hand, the approach of
+% Boshnakov is a bold one – since дж /dzh/ is more often a single
+% consonant, his rules assume that it is always a single consonant.  The
+% number of the cases when this decision leads to bad hyphenations is
+% insignificant in comparison with the cases in which we obtain improved
+% hyphenation.
+% 
+% The third main difference between the patterns of Boshnakov and the
+% patterns of Belogay concerns the eighth rule – its implementation in
+% the rules of Boshnakov is rather limited which leads to wrong
+% hyphenations like бри-дж /bri-dzh/.  A full implementation of this
+% rule would require 11660 patterns in total and this would be too much
+% for the computers in 1994.
+% 
+% Later developments
+% ------------------
+% 
+% In 1995 Atanas Topalov defended a Masters thesis in the Faculty of
+% Mathematics and Informatics at Sofia University titled "Algorithms and
+% software about text processing".[^9] One of the main topics in his
+% thesis was the Bulgarian hyphenation.  Topalov criticised vehemently
+% the official hyphenation rules and their total disregard of the
+% morphology.  He wrote:
+% 
+% > If we look at the history of the problems of the hyphenation, we
+% > will discover something very strange.  Instead of the expected
+% > involvement with the depths and aspiration for more admissible and
+% > satisfactory style, we can find a growing tendency for
+% > simplification.  One unpleasant discovery is that the development of
+% > the hyphenation software stays firmly on the principle "let us do
+% > the easiest thing".  The earliest works which have been studied are
+% > from 1978.  It turned out that they present the best approach
+% > concerning the automated hyphenation.  The authors have chosen the
+% > most difficult but the most correct (from literary point of view)
+% > method for hyphenation, namely the morphological approach.
+% 
+% Topalov proposed his own hyphenation algorithm.  The hyphenation it
+% generated was smooth and easy to read.  One obvious defect of the
+% algorithm of Topalov was that it contradicted the official hyphenation
+% rules at that time.  One can argue, however, that his algorithm is
+% compatible with the current hyphenation rules.
+% 
+% [^9]: The thesis of Atanas Topalov can be accessed at the author's
+%     website <http://www.mind-print.com>
+% 
+% In 1999 Svetla Koeva[^10] wrote a paper about the automated Bulgarian
+% hyphenation.[^11] At that time she was a junior member of the
+% Department of Computational Linguistics at the Institute for Bulgarian
+% Language but now she is a director of the whole institute.  The paper
+% of Koeva contains a list of hyphenation patterns which can be used as
+% a basis of automated hyphenation.  In 2004 with the help of Stoyan
+% Mihov[^12] the rules of Koeva were formalised with regular relations
+% and rewriting rules.  They were implemented in a software product
+% named ItaEst which provided Bulgarian hyphenation and grammar checking
+% for various software products of Microsoft and Apple.

+%     ред. Български език. 1999/2000, 1, 84-86
+% 
+% [^12]: <http://lml.bas.bg/~stoyan/>
+% 
+% The main differences between the hyphenation of Koeva and the official
+% hyphenation rules effective after 2012 is that the separation of a
+% long sequence of consonants between two vowels is done according to
+% the rules valid before 1983.  For example се-стра /se-stra/ and
+% ай-сберг /ay-sberg/ are permitted.  The main difference between the
+% hyphenation of Koeva and the official hyphenation rules effective
+% before 1983 is that the rules of Koeva disregard the morphology of the
+% words.  The following rule of Koeva is specific: in a sequence of two
+% sonorant consonants between two vowels, we are permitted to separate
+% the first vowel from the first consonant, for example материа-лна
+% /materia-lna/.
+% 
+% In 2000 Anton Zinoviev[^13] created new hyphenation patterns for TeX.
+% He didn't know about the previous work of Boshnakov and he didn't
+% bother to make his work available in the various TeX distributions and
+% CTAN.  His work was used mostly by the local Linux enthusiasts and the
+% colleagues of Zinoviev.  In 2001 Radostin Radnev[^14] created a free
+% grammar dictionary of Bulgarian[^15] where he used the hyphenation
+% patterns of Zinoviev.  From there the work of Zinoviev propagated to
+% OpenOffice, LibreOffice and various online dictionaries, including
+% <http://bg.wiktionary.org> and <http://rechnik.chitanka.info>.

+% 
+% [^14]: <http://bg.linkedin.com/in/radostinradnev>
+% 
+% [^15]: <http://bgoffice.sourceforge.net/>
+% 
+% The following are the main differences between the hyphenation of
+% Zinoviev and the hyphenation of Boshnakov.
+% 
+% First, the eighth rule of Belogay is fully implemented.
+% 
+% Second, the rules of Zinoviev try to detect when the letters дж /dzh/
+% (and дз /dz/) denote a single consonant and when they denote a
+% sequence of two consonants.  By default, however, Zinoviev (like
+% Boshnakov) assumes that дж /dzh/ is a single consonant and hyphenates
+% accordingly.
+% 
+% Third, the rules of Zinoviev disable some cases of unpleasant
+% hyphenations:
+% 
+% 1. In a consonant sequence like тст /tst/, the two equal consonants т
+%    /t/ are separated.  For example братст-во /bratst-vo/ is forbidden
+%    while братс-тво /brats-tvo/ and брат-ство /brat-stvo/ are
+%    permitted.
+% 2. The hyphenation is forbidden after a sonorant consonant following
+%    an obstruent consonant.  For example отм-ра /otm-ra/ is forbidden
+%    and от-мра /ot-mra/ is permitted.
+% 3. The hyphenation separates two consecutive kindred voiced/voiceless
+%    consonants.  For example субп-родукт /subp-roduct/ is forbidden and
+%    суб-продукт /sub-product/ is permitted.
+% 
+% At the start of his work on the Bulgarian hyphenation, Zinoviev had
+% the opportunity to discuss the hyphenation with Svetla Koeva.  He
+% remembers that some cases of unpleasant hyphenation were suggested to
+% him by Koeva.  Unfortunately, he hasn't taken notes so now he doesn't
+% know which cases of unpleasant hyphenation have been suggested to him
+% by Koeva and which are his own findings.
+% 
+% The present work
+% ================
+% 
+% Motivation
+% ----------
+% 
+% The present work was carried out on the initiative of the leader of
+% the Bulgarian localisation team of Mozilla, who contacted Zinoviev,
+% Boshnakov and the maintainers of the TeX hyphenation patterns.[^17]
+% This work pursues the following main objectives:
+% 
+% 1. to update the hyphenation patterns in accordance with the current
+%    hyphenation rules;
+% 2. to generate the hyphenation patterns by a publicly available
+%    script;
+% 3. to make the hyphenation patterns customisable;
+% 4. to provide documentation for the future developers.
+% 
+% [^16]: <http://mozillians.org/en-US/u/stoyan/>
+% 
+% [^17]: <http://hyphenation.org>
+% 
+% The current official hyphenating rules for Bulgarian are rather
+% liberal.  Very often, in a long sequence of consonants we are
+% permitted to split the word at any position, for example аген-т-с-т-во
+% /agen-t-s-t-vo/.  This is prone to many unusual and unexpected results
+% that interrupt the attention of the reader or deceive his expectations
+% during the movement of his eyes to the next line.  On the other hand,
+% in order to produce nice justified paragraphs there is no need for so
+% many hyphenation possibilities.  It would be sufficient even if only
+% one possible separation between any two syllables was permitted.
+% 
+% Therefore, it makes sense to use a more restrictive version of the
+% Bulgarian hyphenation, one which eliminates the controversial cases of
+% hyphenation.  Only when typesetting a Bulgarian text in a very narrow
+% newspaper column it will be appropriate to use a more liberal version.
+% It should be noted that some specialised English dictionaries also
+% separate the word-division positions into two categories – preferred
+% positions and less recommended positions.
+% 
+% There are two methods to determine the optimal division within a
+% sequence of consonants between two vowels:
+% 
+% * we can hyphenate according to the syllables in the word or
+% * we can hyphenate morphologically.
+% 
+% Hyphenation according to the syllables in the word
+% --------------------------------------------------
+% 
+% Let us look at the properties of the Bulgarian syllables.  All
+% syllables have the following structure:
+% 
+% > onset - nucleus - code
+% 
+% The nucleus in Bulgarian is always a vowel.  Both the onset and the
+% code are (possibly empty) sequences of consonants.
+% 
+% The Bulgarian syllables adhere to the Sonority Sequencing Principle.
+% According to this principle, the consonants within the onset have
+% raising sonority and the consonants within the code have decreasing
+% sonority.
+% 
+% Several grammar books agree that the following sonority scale is valid
+% for Bulgarian:
+% 
+% > voiceless obtrusive < voiced obtrusive < sonorant consonant < vowel
+% 
+% According to the investigations of the author, the only exception to
+% this law is due to the letter в /v/ which is a voiced obtrusive but it
+% can be used also as a voiceless obtrusive.  This exception is due to a
+% spelling particularity of the Bulgarian language.  Whenever the letter
+% в /v/ seemingly violates the Sonority Sequencing Principle, in the
+% spoken language this letter is read as ф /f/, that is as a voiceless
+% obtrusive (for example the word отвсякъде /otvsyakade/ is read as
+% отфсякъде /otfsyakade/).[^18]
+% 
+% [^18]: No Primitive Slavonic word contains the phoneme ф /f/.
+% Therefore, we can safely assume that in the Primitive Slavonic
+% language the consonant ф /f/ was a positional variant of the consonant
+% в /v/.
+% 
+% The author has found that the sonorant consonants in Bulgarian have
+% their own sonority scale:
+% 
+% > м /m/ < н /n/ < л /l/ < р /r/ < й /y/
+% 
+% Only a few words such as жанр /zhanr/ and химн /himn/ violate this
+% scale.  Such words are always loan-words and their pronunciation is
+% somewhat problematic for the native Bulgarian speakers.
+% 
+% In addition to the Sonority Sequencing Principle, the consonant
+% clusters within the Bulgarian syllable adhere to the following
+% additional principles:
+% 
+% 1. Both in the onset and in the code, the labial and dorsal plosives
+%    precede the coronal plosives and affricates.
+% 2. If the onset or the code contains two plosives or affricates, then
+%    there are no fricatives between them.  Few words with the Latin
+%    root 'text' are exceptions: контекст /kontekst/.
+% 3. If the onset or the code contains two fricatives other than в /v/,
+%    then there are no plosives or affricates between them.
+% 4. If the onset or the code contains two plosives or affricates, then
+%    they both have equal sonority (both are voiced, or both are
+%    voiceless).
+% 5. If the onset or the code contains two fricatives other than в /v/,
+%    then they both have equal sonority (both are voiced, or both are
+%    voiceless).
+% 6. Neither the onset, nor the code may contain two labial plosives, or
+%    two coronal plosives or affricates or two dorsal plosives.
+% 7. Neither the onset, nor the code may contain two equal consonants
+%    with the exception of в /v/ (for example втвърди /vtvardi/).[^19]
+% 
+% [^19]: Actually, the letter в /v/ is not a real exception because in
+% all such cases this letter denotes two different consonants – в /v/
+% and ф /f/.  Only in the Russian loan-word взвод /vzvod/ the two
+% letters в /v/ denote a repeating consonant в /v/.
+% 
+% From all these properties of the Bulgarian syllable we can deduce the
+% following hyphenation rules:
+% 
+% 1. In a sequence МК where М is a consonant with higher sonority than
+%    K, we are not permitted to hyphenate before М.  Exception: when М
+%    is в /v/ and К is a voiceless consonant.
+% 2. In a sequence КМ where М is a consonant with higher sonority than
+%    K, we are not permitted to hyphenate after М.
+% 3. In a sequence KBT where K and T are plosives or affricates and B is
+%    fricative, we separate K from T.
+% 4. In a sequence CKB where K is a plosive or affricate and C and B are
+%    fricatives other than в /v/, we separate C from B.
+% 5. If in a consonant sequence a coronal plosive or affricate Т is
+%    followed by a labial or dorsal plosive К, then we separate Т from К.
+% 6. If a consonant sequence contains two plosives or affricates, one
+%    voiced and one voiceless, then we separate them.
+% 7. If a consonant sequence contains two fricatives other than в /v/,
+%    one voiced and one voiceless, then we separate them.
+% 8. If a consonant sequence contains two labial plosives or two coronal
+%    plosives or affricates or two dorsal plosives then they are
+%    separated.
+% 9. If a consonant sequence contains two equal consonants (not
+%    necessarily consecutive), then they are separated.
+% 
+% With so many prohibitive rules, a question arises: if we apply all
+% these rules, aren't we going to eliminate too many hyphenation
+% possibilities?  The answer is no.  It can be demonstrated that between
+% any two consecutive syllables at least one separation point will be
+% permitted.
+% 
+% 
+% Hyphenation according to the morphology
+% ---------------------------------------
+% 
+% Between 1983 and 2012 the official orthographic rules of the
+% Bulgarian language forbade morphologically based hyphenation.  After
+% 2012 such hyphenation is permitted (but not obligatory).
+% 
+% The most important case when it is very desirable to use
+% morphologically based hyphenation is the case of the compound words.
+% Divisions such as авток-луб /avtok-lub/ and вакуу-мапарат
+% /vakuu-maparat/ are extremely irritating even if they are formally
+% correct.  Unfortunately, we do not have a vocabulary of the compound
+% Bulgarian words that would permit us to produce rules for automated
+% hyphenation.  Therefore, the current Bulgarian hyphenation patterns do
+% not attempt to apply morphological hyphenation to such words.
+% 
+% Second in importance (but far more significant in terms of numbers) is
+% the case with the word prefixes.  While the eyes of the reader still
+% look at the start of the word, the word is still unknown to him.  At
+% this point, it is very important not to deceive his expectations.  For
+% example, when the reader sees над- /nad-/ at the end of the line, he
+% will expect that this is the prefix над- /nad-/ with semantics 'attain
+% more than'.  This expectation will be fooled if this wasn't really a
+% prefix, but a deceiving (while formally correct) hyphenation of the
+% word надремя /nadremya/ 'have dozed enough' where the real prefix is
+% not над- /nad-/ but на- /na-/ with semantics 'achieve a state after
+% accumulation'.  Such hyphenation distracts the reader and makes the
+% reading more difficult.
+% 
+% Third in importance is the case with the word suffixes.  With respect
+% to the hyphenation rules we can divide the suffixes into three
+% categories:
+% 
+% 1. Suffixes starting with a vowel, for example -ар /-ar/.  It is not
+%    appropriate to follow the morphology with such suffixes because
+%    this will contradict the whole hyphenation tradition of the
+%    Bulgarian language.  For example крав-ар /krav-ar/ is unwarranted.
+% 2. Suffixes starting with one consonant, for example -ка /-ka/.
+%    Usually with such suffixes the syllable boundary in the word
+%    coincides with morpheme boundary so no specific cares are
+%    necessary, for example кравар-ка /kravar-ka/.  The exceptions are
+%    rare, for example: обек-тната /obek-tnata/ instead of обект-ната
+%    /obekt-nata/.
+% 3. Suffixes starting with more than one consonant (-ски /-ski/, -ство
+%    /-stvo/).  It is possible to use morphological hyphenation rules
+%    with such suffixes.
+% 
+% Even if it is possible to use morphological hyphenation with the
+% suffixes of the third category, it turns out, this is not as useful as
+% it is with the case of the prefixes.  When the eyes of the reader have
+% reached this part of the word, the word is already more or less known
+% to the reader.  Therefore, at this point the morphological hyphenation
+% does not provide any significant advantages in comparison to the
+% simpler hyphenation based only on the syllables in the word.  Consider
+% for example the word геройс-тво /geroys-tvo/ with suffix -ство
+% /-stvo/.  When the reader sees геройс- /geroys-/ at the end of the
+% line this will give him an early clue that the suffix of the word is
+% -ство /-stvo/.  Such non-morphological hyphenation does not deceive
+% the expectations of the reader.  On the contrary, it makes the reading
+% easier because it gives clues to the reader about what follows on the
+% next line.
+% 
+% Because of these considerations, the current Bulgarian hyphenation
+% patterns do not attempt to use morphological hyphenation with respect
+% to the suffixes of the words.  Though it would be useful to implement
+% rules about the suffixes of the second cateogory.  Hopefully, some
+% future version will have such rules.
+% 
+% Occasionally,[^20] a fourth morphological requirement is stated: that
+% hyphenation should conform with the boundary between the word and the
+% definitive articles -та /-ta/ and -те /-te/ (postfixed in Bulgarian).
+% There is no need to pay attention to this rule because it seems to be
+% satisfied by its own nature.  The author has searched in a dictionary
+% with over 860000 Bulgarian words for cases when the hyphenation rules
+% would hyphenate badly with respect to the definitive article.  He was
+% unable to find even one such case with the hyphenation rules valid
+% after 1983 and only about 10 cases with the rules valid before 1983
+% (one of them is живопи-ста /zhivopi-sta/ instead of живопис-та
+% /zhivopis-ta/).
+% 
+% One unavoidable characteristic of any morphologically based automated
+% hyphenation is that it can create wrong hyphenations.  Because of
+% this, one useful option is to use the morphology in a safe way – to
+% use it in order to forbid bad hyphenations but to create no new
+% hyphenation possibilities solely on the basis of the morphology.
+% 
+% Take for example the word дозрея /dozreya/ 'ripen fully'.  According
+% to the phonological rules, we should hyphenate it as доз-рея
+% /doz-reya/.  According to the morphology, however, we should hyphenate
+% as до-зрея /do-zreyq/ because this word is formed with the prefix до-
+% /do-/ with semantics 'complete or supplement' and this semantics would
+% be lost if the reader sees доз- /doz-/ at the end of the line.
+% Therefore, there are three methods to hyphenate this word:
+% 
+% 1. доз-рея /doz-reya/ when morphology is not used;
+% 2. до-зрея /do-zreya/ when morphology is fully used;
+% 3. дозрея /dozreya/ (no hyphenation) when morphology is used in a safe
+%    way.
+% 
+% The option to use the morphology in a safe way is very attractive when
+% the software uses a smart line-breaking algorithm which can produce
+% good results even with less hyphenation possibilities.  TeX is one
+% such software.  It should be noted that this option does not eliminate
+% too many hyphenation possibilities because the morpheme boundaries
+% most of the time are also syllable boundaries.

+%     Цв. Минков; Ред. Ив. Хаджов и др. София, Бълг. кн., 1945
+% 
+% The following are results of a statistics about the quality of the
+% morphological rules (the number after the sign ± is the expected
+% standard deviation of our estimations):
+% 
+% With the option `--morphology`:
+% 
+% * in 0.1% ±0.3% of the dictionary words the morphological patterns
+%   create very wrong hyphenation;
+% * in 89.8% ±0.1% of the dictionary words the morphological patterns
+%   hyphenate identically with the case when no morphology patterns are
+%   used;
+% * in 0.3% ±0.2% of the dictionary words the morphological patterns
+%   hyphenate differently in comparison to the case when no morphology
+%   patterns are used and the word is hyphenated in a way which
+%   contradicts the morphology;
+% * in 0.6% ±0.1% of the dictionary words the morphological patterns
+%   hyphenate differently in comparison to the case when no morphology
+%   patterns are used and there is a possible hyphenation which is
+%   compatible with the word morphology but which is nevertheless
+%   forbidden by the morphology patterns.
+%   
+% With the option `--safe-morphology`:
+% 
+% * in 0% of the dictionary words the morphological patterns create very
+%   wrong hyphenation;
+% * in 90.0% ±0.1% of the dictionary words the morphological patterns
+%   hyphenate identically with the case when no morphology patterns are
+%   used;
+% * in 0.3% ±0.2% of the dictionary words the morphological patterns
+%   hyphenate differently in comparison to the case when no morphology
+%   patterns are used and the word is hyphenated in a way which
+%   contradicts the morphology;
+% * in 0.6% ±0.1% of the dictionary words the morphological patterns
+%   hyphenate differently in comparison to the case when no morphology
+%   patterns are used and there is a possible hyphenation which is
+%   compatible both with the word morphology and with the syllable
+%   boundaries but which is nevertheless forbidden by the morphology
+%   patterns.
+%   
+% Notice that the morphological patterns create a different hyphenation
+% only in about 10% of the words.  The following explanation can be
+% given for this surprising fact.  First, the natural evolution of the
+% human languages tends to simplify the complex sequences of consonants.
+% Therefore, no morpheme contains a complex sequence of consonants.  And
+% second, the Bulgarian orthography is morphological.  This means that
+% the morphemes are written according to their actual pronunciation,
+% however the simplifications in the spoken languages which take place
+% at the morpheme boundaries are not taken into account in the
+% orthography.  The independent operation of these two factors leads to
+% the result that most of the time the morpheme boundaries coincide with
+% the conventional syllable boundaries.  The main exception to this is
+% when a morpheme starts with a vowel, in this case its syllable will
+% include one or more consonants of the preceeding morpheme.  The second
+% exception is when a morpheme ends with a vowel and the next morpheme
+% starts with a sequence of two or more consonants.
+% 
+% Usage of the script `hyph-bg.sh`
+% --------------------------------
+% 
+% The `hyph-bg.sh` is all-in-one script which can generate both
+% documentation (this text) and Bulgarian hyphenation patterns.  When
+% given the option `--help` the script gives short usage instructions:
+% 
+% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+% hyph-bg.sh --help
+%           Show this info
+% hyph-bg.sh [--doc-html | --doc-latex | --doc-txt]
+%           Print documentation in various formats
+% hyph-bg.sh [other options]
+%           Generate Bulgarian hyphenation patterns
+% 
+% Options when generating hyphenation patterns:
+% 
+%  --standalone-tex
+%           Produce hyphenation patterns for TeX with \patterns{ ... }.
+% 
+%  --no-hyphen-mins
+%           Hyphenation patterns which do not require hyphen mins.
+%           Otherwise: both left and right hyphen mins should be set to 2.
+% 
+%  --safe-dz
+%           Do not try to guess whether DZ is a single consonant or not.
+%           Only use hyphenation which will be correct in both cases.
+% 
+%  --permissible
+%           Permit any formally correct hyphenation, including unnatural
+%           divisions, such as studen-tstvo.  Useful for educational tools
+%           or when typesetting Bulgarian text in a very short column.
+% 
+%  --morphology
+%           Apply morphology when hyphenating, for example: za-dvizhvam.
+%           May hyphenate incorrectly in some cases.
+% 
+%  --safe-morphology
+%           Apply morphology when hyphenating.  Never hyphenates incorrectly
+%           but may prohibit some correct hyphenations.
+% 
+%  --no-morphology
+%           Disregard the morphology.  Default.
+% 
+%  --1945
+%           Hyphenate according to the rules effective between 1945 and 1982
+% 
+%  --1983
+%           Hyphenate according to the rules effective between 1983 and 2011
+% 
+%  --2012
+%           Hyphenate according to the rules effective after 2012.  Default.
+% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+% 
+% The following are the recommended ways to generate hyphenation
+% patterns by this script:
+% 
+% `hyph-bg.sh --standalone-tex --safe-morphology`
+% :   For TeX.  Apply the morphology in a safe way when the software
+%     uses a smart line-breaking algorithm.
+% 
+% `hyph-bg.sh`
+% :   For most other software.
+% 
+% `hyph-bg.sh --no-hyphen-mins`
+% :   The current versions of Mozilla (as of 2017) seem to ignore the
+%     hyphen mins in words that contain a dash.
+% 
+% `hyph-bg.sh --morphology`
+% :   For professional typography with human proof-reader.
+% 
+% `hyph-bg.sh --permissible`
+% :   For educational tools and online dictionaries which can show only one
+%     kind of hyphenation.
+% 
+% Notice that some specialised English dictionaries separate the
+% word-division positions into two categories – preferred positions and
+% less recommended positions.  It would be best if the Bulgarian online
+% dictionaries could do the same.  For example hyphen "-" can be used to
+% display the preferred positions and dot "." – the less recommended
+% positions.  If a word-division position is permitted only by the
+% patterns of `hyph-bg.sh --permissible`, then this position is less
+% recommended.

 % Patterns for the latin language mainly in modern spelling
 % (u when u is needed and v when v is needed); medieval spelling
 % with the ligatures \ae and \oe  and the (uncial) lowercase `v'
 % written as a `u' is also supported; apparently there is no conflict
 % between the patterns of modern  Latin and those of medieval Latin.

+% Principles of the Bulgarian hyphenation\
+% =======================================\
+% \
+% One specificity of the Bulgarian language is that the average length\
+% of the words is greater than in English.  When typesetting a Bulgarian\
+% text, hyphenation is more important than when typesetting an English\
+% text.  Knuth's algorithm for line-breaking is such that in most\
+% English paragraphs no hyphenation will be used.  With a Bulgarian\
+% text, however, even the Knuth's algorithm will use hyphenation in most\
+% paragraphs.  Hyphenation becomes an absolute necessity if we want to\
+% obtain nice, justified paragraphs when using a software with dumb\
+% line-breaking algorithm, such as LibreOffice.\
+% \
+% According to Decree 936 of the Council of Ministers promulgated on 27\
+% November 1950, the Institute for Bulgarian Language at the Bulgarian\
+% Academy of Sciences is authorised to publish the rules of the\
+% orthography of the Bulgarian language (within certain limits).\
+% \
+% Hyphenation rules between 1945 and 1983\
+% ---------------------------------------\
+% \
+% Between 1945 and 1983 Bulgarian used syllable hyphenation with two\
+% morphological exceptions: hyphenation is preferred between a prefix\
+% and a stem and at the boundary of compound words.  The following were\
+% the rules governing the hyphenation:\
+% \
+% 1. One letter does not stay alone.  Words of one syllable can not be\
+%    hyphenated.\
+% 2. No hyphenation before or after ь.\
+% 3. In a sequence of vowels at least one vowel stays before the\
+%    hyphen.\
+% 4. A single consonant between two vowels links with the second vowel.\
+%    For example по-ле /po-le/, ра-бо-та /ra-bo-ta/.\
+% 5. In a sequence of consonants between two vowels, at least one\
+%    consonant stays with the second vowel.  For example те-сто /te-sto/\
+%    or тес-то /tes-to/.[^b]\
+% 6. In a sequence of consonants between two vowels, if the first\
+%    consonant is sonorant (й /y/, л /l/, м /m/, н /n/, р /r/), then it\
+%    stays with the first vowel.  For example гер-дан /ger-dan/, сен-ки\
+%    /sen-ki/.\
+% 7. The hyphenation separates two successive equal consonants. For\
+%    example времен-но /vremen-no/, пролет-та /prolet-ta/.\
+% 8. When the letters дж /dzh/ and дз /dz/ denote a single consonant,\
+%    then they are not separated.  For example боя-джия /boya-dzhiya/\
+%    but not бояд-жия /boyad-zhiya/.  When these letters denote two\
+%    consonants, then the normal rules apply: над-живявам\
+%    /nad-zhivyavam/.\
+% 9. Word prefixes may not be broken.  Compound words are hyphenated\
+%    either at the boundary of the components or the hyphenation rules\
+%    are applied to each of the components separately.  For example:\
+%    пред-упреждавам /pred-uprezhdavam/ (not пре-дупреждавам\
+%    /pre-duprezhdavam/), пред-известие /pred-izvestie/ (not\
+%    пре-дизвестие /pre-dizvestie/), за-движвам /za-dvizhvam/ (not\
+%    зад-вижвам /zad-vizhvam/), авто-клуб /avto-klub/ (not авток-луб\
+%    /avtok-lub/), вакуум-апарат /vakuum-aparat/ (not вакуу-мапарат\
+%    /vakuu-maparat/).\
+% \
+% In some rare cases the proper application of rule 9 depends on the\
+% semantics of the word.  For example пре-дреша /pre-dresha/ 'change\
+% clothes' but пред-реша /pred-resha/ 'predetermine' or прес-пите\
+% /pres-pite/ 'the snow-drifts' but пре-спите /pre-spite/ 'sleep for a\
+% while/overnight'.\
+% \
+% [^b]: In several publications this rule is formulated with the\
+%     additional restriction that the sequence of consonants begins with\
+%     an obstruent.  I believe this restriction is unintentional.  It\
+%     makes no sense to forbid a hyphenation of the form AB-A but to\
+%     permit ABB-A (A denotes a vowel and B – a consonant).\
+% \
+% Hyphenation rules between 1983 and 2012\
+% ---------------------------------------\
+% \
+% The Orthographic dictionary published by the Institute for Bulgarian\
+% language in 1983 introduced new hyphenation rules.  The complexity of\
+% the previous rules was the main reason for the change.  The new rules\
+% aimed at two objectives: simplicity and unambiguity.\
+% \
+% The new rules are:\
+% \
+% 1. A consonant between two vowels links with the second vowel.  For\
+%    example ви-со-чи-на /vi-so-chi-na/.\
+% 2. In a sequence of two or more consonants between two vowels, at\
+%    least one consonant stays with first vowel and at least one with\
+%    the second vowel.  For example сес-тра /ses-tra/ and сест-ра\
+%    /sest-ra/.\
+% 3. Two equal consonants are separated.  For example плен-ник\
+%    /plen-nik/.\
+% 4. In a sequence of two or more vowels, the first vowel stays before\
+%    the hyphen.  For example пре-одолея /pre-odoleya/ and прео-долея\
+%    /preo-doleya/.\
+% 5. In a sequence of three or more vowels, the last vowel stays after\
+%    the hyphen.  For example мао-изъм /mao-izam/ but not маои-зъм\
+%    /maoi-zam/.\
+% 6. The letter й /y/ between a vowel and a consonant stays with the\
+%    vowel.  For example май-ка /may-ka/.\
+% 7. When a sequence of two or more consonants follows й /y/ then at\
+%    least one consonant links with й /y/.  For example айс-берг\
+%    /ays-berg/ (not ай-сберг /ay-sberg/).\
+% 8. The letter й /y/ between two vowels links with the second vowel.\
+%    For example ма-йор /ma-yor/.\
+% 9. No hyphenation before or after ь.\
+% 10. When the letters дж /dzh/ denote a single consonant, then they are\
+%     not separated.  For example су-джук /su-dzhuk/ (not суд-жук\
+%     /sud-zhuk/) but над-живея /nad-zhiveya/.\
+% 11. There must be at least one vowel before and after the hyphen.\
+% 12. One letter does not stay alone.\
+% \
+% The total disregard of the morphology by these rules leads to some\
+% strange results.  For example пре-дизвестие /pre-dizvestie/ is\
+% permitted and пред-известие /pred-izvestie/ is forbidden, зад-вижвам\
+% /zad-vizhvam/ is permitted and за-движвам /za-dvizhvam/ is forbidden,\
+% авток-луб /avtok-lub/ is permitted and авто-клуб /avto-klub/ is\
+% forbidden, вакуу-мапарат /vakuu-maparat/ is permitted and\
+% вакуум-апарат /vakuum-aparat/ is forbidden.  Because of this, the new\
+% rules were not universally accepted.  The old rules are still\
+% mentioned in various places in Internet, they are included even in\
+% some grammar books published by the publishing houses of the Ministry\
+% of Education and of Sofia University.  The software developers,\
+% however, soon came into love with the new hyphenation rules.\
+% \
+% Hyphenation rules after 2012\
+% ----------------------------\
+% \
+% In 2012 new rules came into force.  There are two differences with\
+% respect to the previous rules:\
+% \
+% 1. Rule 5 of the previous rules is revoked.  For example маои-зъм\
+%    /maoi-zam/ becomes a valid hyphenation.\
+% 2. The new rules permit morphologically based hyphenation (however it\
+%    is not obligatory).  For example пред-известие /pred-izvestie/,\
+%    за-движвам /za-dvizhvam/, авто-клуб /avto-klub/, вакуум-апарат\
+%    /vakuum-aparat/ are valid hyphenations.\
+% \
+% Good hyphenation is a complex matter and it seems the linguists at the\
+% Institute for Bulgarian Language have recognised this.  They no longer\
+% attempt to provide universal rules about everything.  Instead, they\
+% provide some very permissible rules while the good application of\
+% these rules is leaved to the discretion and the experience of the\
+% printers and the developers of hyphenation software.\
+% \
+% It makes sense to use at least two different sets of hyphenation rules\
+% for Bulgarian.  In most cases a more restrictive version should be\
+% used, one which attempts to eliminate the controversial cases of\
+% hyphenation.  When typesetting a Bulgarian text in a narrow newspaper\
+% column, however, it will be appropriate to use more liberal\
+% hyphenation rules.  It should be noted that one of the reasons for the\
+% hyphenation reform in 1983 was the desire to fix the chaotic\
+% hyphenation in the Bulgarian newspapers at that time.\
+% \
+% Computer implementations\
+% ========================\
+% \
+% Mathematical analysis of the Bulgarian hyphenation\
+% --------------------------------------------------\
+% \
+% The earliest mathematical analysis of the Bulgarian hyphenation rules\
+% belongs to Veska Noncheva.[^1] In 1988 she proposed a mathematical\
+% formalisation of the hyphenation rules in a table with 22 rows.[^2]\
+% \
+% [^1]: <http://www.researchgate.net/profile/Veska_Noncheva>\
+% \
+% [^2]: Нончева В. Алгоритъм за автоматично пренасяне на думи в\
+%     българския език. Математика и математическо\
+%     образование. Сб. доклади на 17. ПК на СМБ. С., БАН, 1988, 479-482.\
+% \
+% In the same year Eugene Belogay[^3] proposed an alternative\
+% formalisation with only 9 rules.[^4] Belogay proved that his rules are\
+% consistent and that they form a minimal set.  The rules of Belogay\
+% have negative character – every hyphenation which is not forbidden by\
+% a rule is possible hyphenation.\
+% \

+% \
+% [^4]: Белогай Е. Алгоритъм за автоматично пренасяне на думи. Компютър\
+%     за вас (1988) 3, 12-14.\
+% \
+% The following are the first 7 rules, as formulated by Belogay:\
+% \
+% 1. Б-А\
+% 2. А-ББ\
+% 3. Б-ТТ, ТТ-Б\
+% 4. ААА-Б\
+% 5. й-ББ\
+% 6. Б-ь\
+% 7. д-ж\
+% \
+% Here А denotes an arbitrary vowel letter, Б denotes an arbitrary\
+% consonant letter (including ь and й), ТТ denotes a sequence of two\
+% equal consonant letters and the letters й, ь, д and ж denote\
+% themselves.  For example the rule \"Б-А\" says that we are not permitted\
+% to separate a consonant letter from immediately following vowel\
+% letter.\
+% \
+% The eighth rule of Belogay says that hyphenation is forbidden before\
+% the first and after the last vowel letter.  The ninth rule of Belogay\
+% says that hyphenation is forbidden immediately after the first or\
+% immediately before the last letter of the word.\
+% \
+% Notice that is is very easy to translate the rules of Belogay in the\
+% form, required for the hyphenation algorithm of Knuth and Liang used\
+% in TeX.[^a] Let us remind that this algorithm matches the word with a\
+% set of string patterns in which the odd numbers say hyphenation is\
+% permitted in this position and even numbers say the hyphenation is\
+% forbidden.  When two patterns give conflicting numbers for the same\
+% position, then the greater number wins.\
+% \
+% First, since the rules of Belogay are negative (they say where\
+% hyphenation is forbidden, not where it is permitted), we have to\
+% permit the hyphenation everywhere:\
+% \
+% 1. А1\
+% 2. Б1\
+% \
+% Then, the first seven rules of Belogay obtain the form:\
+% \
+% 1. Б2А\
+% 2. А2ББ\
+% 3. Б2ТТ ТТ2Б\
+% 4. ААА2Б\
+% 5. й2ББ\
+% 6. Б2ь\
+% 7. д2ж\
+% \
+% Since no Bulgarian word starts with more that four consonants and no\
+% Bulgarian word ends with more than three consonants, the eighth rule\
+% of Belogay can be translated in the following way:\
+% \
+% 1. .Б2\
+% 2. .ББ2\
+% 3. .БББ2\
+% 4. 2Б.\
+% 5. 2ББ.\
+% \
+% The ninth rule of Belogay means that left and right hyphen mins should\
+% be set to 2.\
+% \
+% The work of Eugene Belogay was not limited to merely a mathematical\
+% analysis of the Bulgarian hyphenation rules.  In his paper he\
+% published a short algorithm in Pascal which implements these rules.\
+% It didn't take long for this algorithm to be used in various text\
+% processing software.  The algorithm of Belogay was famous for many\
+% years.  Even as late as 1997 in one book about TeX, the author didn't\
+% care to give any explanations but simply wrote about \"the algorithm of\
+% Belogay\" as something well known to the reader.[^5]\

+% \
+% Bulgarian hyphenation in TeX\
+% ----------------------------\
+% \
+% One unfortunate design decision of Knuth was that the hyphenation\
+% algorithm of TeX applied the hyphenation patterns not to the input\
+% character codes but to the internal codes of the glyphs in the font.\
+% This created a problem for the Cyrillic languages because in TeX the\
+% Cyrillic fonts did not have standardised encoding.  Perhaps this is\
+% one of the reasons why the earliest implementations of the Bulgarian\
+% hyphenation in TeX did not rely on the internal hyphenation algorithm\
+% of TeX.  Instead, external tools were used to insert soft hyphens in\
+% all Bulgarian words.  For example such a tool would replace the word\
+% сричкопренасяне /srichkoprenasyane/ with\
+% срич\\\\-коп\\\\-ре\\\\-на\\\\-ся\\\\-не /srich\\\\-kop\\\\-re\\\\-na\\\\-sya\\\\-ne/.\
+% The saying \"To every disadvantage there is a corresponding advantage\"\
+% is true – since Cyrillic and Latin letters use different character\
+% codes, an external tool could easily insert soft hyphens in all\
+% Bulgarian words while leaving the TeX commands intact.\
+% \
+% The earliest known attempt to use the hyphenation algorithm of TeX for\
+% Bulgarian was made by Ognyan Tonev in 1990.[^6] He described his work\
+% as \"a not very good translation of the rules.  I work in this\
+% direction.  But I don't have a 100% working complect of patterns.  So,\
+% the copy I send to you[^7] is only a beta-version.\"  The hyphenation\
+% patterns of Tonev don't work correctly and it seems he never completed\
+% his work.\
+% \
+% [^6]: The author of this text was unable to find current information\
+%     about Ognyan Tonev in Internet.  Apparently in 1990 he worked in\
+%     the Center of Informatics and Computer Technology of the Bulgarian\
+%     Academy of Sciences.\
+% \
+% [^7]: To Yannis Haralambous,\
+%     <http://perso.telecom-bretagne.eu/yannisharalambous>\
+% \
+% The first usable Bulgarian hyphenation patterns for TeX were developed\
+% by Georgi Boshnakov[^8] in 1994.  In order to solve the encoding\
+% problem, Boshnakov had developed TeX fonts supporting the MIK encoding\
+% (the prevalent encoding at that time in Bulgaria).  This allowed him\
+% to introduce a fully working implementation only a few months after\
+% LaTeX2e became the official LaTeX version.  Later Boshnakov modified\
+% his work with the Babel system.  The hyphenation patterns of Boshnakov\
+% did their job well enough, so that for almost quarter a century after\
+% their initial creation, they remained the only Bulgarian hyphenation\
+% patterns in the standard distributions of TeX and CTAN.\
+% \
+% [^8]: <http://www.maths.manchester.ac.uk/~gb/>\
+% \
+% There are some similarities between the patterns of Boshnakov and the\
+% patterns of Belogay.  The following are the main differences.\
+% \
+% First, Boshnakov used an ingenious and more compact implementation of\
+% the second and the third rule.  Instead of {А2ББ, Б2ТТ, ТТ2Б}, or\
+% 8×22×22+22×22+22×22=4840 patterns in total, Boshnakov has patterns of\
+% the form 2Б3Б2 and 4Т3Т4, or only 22×22=484 in total, with the same\
+% effect.\
+% \
+% The second main difference between the patterns of Boshnakov and the\
+% patterns of Belogay concerns the letter combination дж /dzh/.  In\
+% Bulgarian this letter combination can denote either a single\
+% consonant, or a sequence of two consonants and the hyphenation rules\
+% change respectively.  Unfortunately, it is impossible to know the\
+% meaning of дж /dzh/ without a vocabulary.  The solution of Belogay was\
+% a cautious one – his rules do the hyphenation in a way which will be\
+% correct regardless of whether дж /dzh/ is a single consonant or a\
+% sequence of two consonant.  On the other hand, the approach of\
+% Boshnakov is a bold one – since дж /dzh/ is more often a single\
+% consonant, his rules assume that it is always a single consonant.  The\
+% number of the cases when this decision leads to bad hyphenations is\
+% insignificant in comparison with the cases in which we obtain improved\
+% hyphenation.\
+% \
+% The third main difference between the patterns of Boshnakov and the\
+% patterns of Belogay concerns the eighth rule – its implementation in\
+% the rules of Boshnakov is rather limited which leads to wrong\
+% hyphenations like бри-дж /bri-dzh/.  A full implementation of this\
+% rule would require 11660 patterns in total and this would be too much\
+% for the computers in 1994.\
+% \
+% Later developments\
+% ------------------\
+% \
+% In 1995 Atanas Topalov defended a Masters thesis in the Faculty of\
+% Mathematics and Informatics at Sofia University titled \"Algorithms and\
+% software about text processing\".[^9] One of the main topics in his\
+% thesis was the Bulgarian hyphenation.  Topalov criticised vehemently\
+% the official hyphenation rules and their total disregard of the\
+% morphology.  He wrote:\
+% \
+% > If we look at the history of the problems of the hyphenation, we\
+% > will discover something very strange.  Instead of the expected\
+% > involvement with the depths and aspiration for more admissible and\
+% > satisfactory style, we can find a growing tendency for\
+% > simplification.  One unpleasant discovery is that the development of\
+% > the hyphenation software stays firmly on the principle \"let us do\
+% > the easiest thing\".  The earliest works which have been studied are\
+% > from 1978.  It turned out that they present the best approach\
+% > concerning the automated hyphenation.  The authors have chosen the\
+% > most difficult but the most correct (from literary point of view)\
+% > method for hyphenation, namely the morphological approach.\
+% \
+% Topalov proposed his own hyphenation algorithm.  The hyphenation it\
+% generated was smooth and easy to read.  One obvious defect of the\
+% algorithm of Topalov was that it contradicted the official hyphenation\
+% rules at that time.  One can argue, however, that his algorithm is\
+% compatible with the current hyphenation rules.\
+% \
+% [^9]: The thesis of Atanas Topalov can be accessed at the author's\
+%     website <http://www.mind-print.com>\
+% \
+% In 1999 Svetla Koeva[^10] wrote a paper about the automated Bulgarian\
+% hyphenation.[^11] At that time she was a junior member of the\
+% Department of Computational Linguistics at the Institute for Bulgarian\
+% Language but now she is a director of the whole institute.  The paper\
+% of Koeva contains a list of hyphenation patterns which can be used as\
+% a basis of automated hyphenation.  In 2004 with the help of Stoyan\
+% Mihov[^12] the rules of Koeva were formalised with regular relations\
+% and rewriting rules.  They were implemented in a software product\
+% named ItaEst which provided Bulgarian hyphenation and grammar checking\
+% for various software products of Microsoft and Apple.\

+% \
+% [^12]: <http://lml.bas.bg/~stoyan/>\
+% \
+% The main differences between the hyphenation of Koeva and the official\
+% hyphenation rules effective after 2012 is that the separation of a\
+% long sequence of consonants between two vowels is done according to\
+% the rules valid before 1983.  For example се-стра /se-stra/ and\
+% ай-сберг /ay-sberg/ are permitted.  The main difference between the\
+% hyphenation of Koeva and the official hyphenation rules effective\
+% before 1983 is that the rules of Koeva disregard the morphology of the\
+% words.  The following rule of Koeva is specific: in a sequence of two\
+% sonorant consonants between two vowels, we are permitted to separate\
+% the first vowel from the first consonant, for example материа-лна\
+% /materia-lna/.\
+% \
+% In 2000 Anton Zinoviev[^13] created new hyphenation patterns for TeX.\
+% He didn't know about the previous work of Boshnakov and he didn't\
+% bother to make his work available in the various TeX distributions and\
+% CTAN.  His work was used mostly by the local Linux enthusiasts and the\
+% colleagues of Zinoviev.  In 2001 Radostin Radnev[^14] created a free\
+% grammar dictionary of Bulgarian[^15] where he used the hyphenation\
+% patterns of Zinoviev.  From there the work of Zinoviev propagated to\
+% OpenOffice, LibreOffice and various online dictionaries, including\
+% <http://bg.wiktionary.org> and <http://rechnik.chitanka.info>.\

+% \
+% [^14]: <http://bg.linkedin.com/in/radostinradnev>\
+% \
+% [^15]: <http://bgoffice.sourceforge.net/>\
+% \
+% The following are the main differences between the hyphenation of\
+% Zinoviev and the hyphenation of Boshnakov.\
+% \
+% First, the eighth rule of Belogay is fully implemented.\
+% \
+% Second, the rules of Zinoviev try to detect when the letters дж /dzh/\
+% (and дз /dz/) denote a single consonant and when they denote a\
+% sequence of two consonants.  By default, however, Zinoviev (like\
+% Boshnakov) assumes that дж /dzh/ is a single consonant and hyphenates\
+% accordingly.\
+% \
+% Third, the rules of Zinoviev disable some cases of unpleasant\
+% hyphenations:\
+% \
+% 1. In a consonant sequence like тст /tst/, the two equal consonants т\
+%    /t/ are separated.  For example братст-во /bratst-vo/ is forbidden\
+%    while братс-тво /brats-tvo/ and брат-ство /brat-stvo/ are\
+%    permitted.\
+% 2. The hyphenation is forbidden after a sonorant consonant following\
+%    an obstruent consonant.  For example отм-ра /otm-ra/ is forbidden\
+%    and от-мра /ot-mra/ is permitted.\
+% 3. The hyphenation separates two consecutive kindred voiced/voiceless\
+%    consonants.  For example субп-родукт /subp-roduct/ is forbidden and\
+%    суб-продукт /sub-product/ is permitted.\
+% \
+% At the start of his work on the Bulgarian hyphenation, Zinoviev had\
+% the opportunity to discuss the hyphenation with Svetla Koeva.  He\
+% remembers that some cases of unpleasant hyphenation were suggested to\
+% him by Koeva.  Unfortunately, he hasn't taken notes so now he doesn't\
+% know which cases of unpleasant hyphenation have been suggested to him\
+% by Koeva and which are his own findings.\
+% \
+% The present work\
+% ================\
+% \
+% Motivation\
+% ----------\
+% \
+% The present work was carried out on the initiative of the leader of\
+% the Bulgarian localisation team of Mozilla, who contacted Zinoviev,\
+% Boshnakov and the maintainers of the TeX hyphenation patterns.[^17]\
+% This work pursues the following main objectives:\
+% \
+% 1. to update the hyphenation patterns in accordance with the current\
+%    hyphenation rules;\
+% 2. to generate the hyphenation patterns by a publicly available\
+%    script;\
+% 3. to make the hyphenation patterns customisable;\
+% 4. to provide documentation for the future developers.\
+% \
+% [^16]: <http://mozillians.org/en-US/u/stoyan/>\
+% \
+% [^17]: <http://hyphenation.org>\
+% \
+% The current official hyphenating rules for Bulgarian are rather\
+% liberal.  Very often, in a long sequence of consonants we are\
+% permitted to split the word at any position, for example аген-т-с-т-во\
+% /agen-t-s-t-vo/.  This is prone to many unusual and unexpected results\
+% that interrupt the attention of the reader or deceive his expectations\
+% during the movement of his eyes to the next line.  On the other hand,\
+% in order to produce nice justified paragraphs there is no need for so\
+% many hyphenation possibilities.  It would be sufficient even if only\
+% one possible separation between any two syllables was permitted.\
+% \
+% Therefore, it makes sense to use a more restrictive version of the\
+% Bulgarian hyphenation, one which eliminates the controversial cases of\
+% hyphenation.  Only when typesetting a Bulgarian text in a very narrow\
+% newspaper column it will be appropriate to use a more liberal version.\
+% It should be noted that some specialised English dictionaries also\
+% separate the word-division positions into two categories – preferred\
+% positions and less recommended positions.\
+% \
+% There are two methods to determine the optimal division within a\
+% sequence of consonants between two vowels:\
+% \
+% * we can hyphenate according to the syllables in the word or\
+% * we can hyphenate morphologically.\
+% \
+% Hyphenation according to the syllables in the word\
+% --------------------------------------------------\
+% \
+% Let us look at the properties of the Bulgarian syllables.  All\
+% syllables have the following structure:\
+% \
+% > onset - nucleus - code\
+% \
+% The nucleus in Bulgarian is always a vowel.  Both the onset and the\
+% code are (possibly empty) sequences of consonants.\
+% \
+% The Bulgarian syllables adhere to the Sonority Sequencing Principle.\
+% According to this principle, the consonants within the onset have\
+% raising sonority and the consonants within the code have decreasing\
+% sonority.\
+% \
+% Several grammar books agree that the following sonority scale is valid\
+% for Bulgarian:\
+% \
+% > voiceless obtrusive < voiced obtrusive < sonorant consonant < vowel\
+% \
+% According to the investigations of the author, the only exception to\
+% this law is due to the letter в /v/ which is a voiced obtrusive but it\
+% can be used also as a voiceless obtrusive.  This exception is due to a\
+% spelling particularity of the Bulgarian language.  Whenever the letter\
+% в /v/ seemingly violates the Sonority Sequencing Principle, in the\
+% spoken language this letter is read as ф /f/, that is as a voiceless\
+% obtrusive (for example the word отвсякъде /otvsyakade/ is read as\
+% отфсякъде /otfsyakade/).[^18]\
+% \
+% [^18]: No Primitive Slavonic word contains the phoneme ф /f/.\
+% Therefore, we can safely assume that in the Primitive Slavonic\
+% language the consonant ф /f/ was a positional variant of the consonant\
+% в /v/.\
+% \
+% The author has found that the sonorant consonants in Bulgarian have\
+% their own sonority scale:\
+% \
+% > м /m/ < н /n/ < л /l/ < р /r/ < й /y/\
+% \
+% Only a few words such as жанр /zhanr/ and химн /himn/ violate this\
+% scale.  Such words are always loan-words and their pronunciation is\
+% somewhat problematic for the native Bulgarian speakers.\
+% \
+% In addition to the Sonority Sequencing Principle, the consonant\
+% clusters within the Bulgarian syllable adhere to the following\
+% additional principles:\
+% \
+% 1. Both in the onset and in the code, the labial and dorsal plosives\
+%    precede the coronal plosives and affricates.\
+% 2. If the onset or the code contains two plosives or affricates, then\
+%    there are no fricatives between them.  Few words with the Latin\
+%    root 'text' are exceptions: контекст /kontekst/.\
+% 3. If the onset or the code contains two fricatives other than в /v/,\
+%    then there are no plosives or affricates between them.\
+% 4. If the onset or the code contains two plosives or affricates, then\
+%    they both have equal sonority (both are voiced, or both are\
+%    voiceless).\
+% 5. If the onset or the code contains two fricatives other than в /v/,\
+%    then they both have equal sonority (both are voiced, or both are\
+%    voiceless).\
+% 6. Neither the onset, nor the code may contain two labial plosives, or\
+%    two coronal plosives or affricates or two dorsal plosives.\
+% 7. Neither the onset, nor the code may contain two equal consonants\
+%    with the exception of в /v/ (for example втвърди /vtvardi/).[^19]\
+% \
+% [^19]: Actually, the letter в /v/ is not a real exception because in\
+% all such cases this letter denotes two different consonants – в /v/\
+% and ф /f/.  Only in the Russian loan-word взвод /vzvod/ the two\
+% letters в /v/ denote a repeating consonant в /v/.\
+% \
+% From all these properties of the Bulgarian syllable we can deduce the\
+% following hyphenation rules:\
+% \
+% 1. In a sequence МК where М is a consonant with higher sonority than\
+%    K, we are not permitted to hyphenate before М.  Exception: when М\
+%    is в /v/ and К is a voiceless consonant.\
+% 2. In a sequence КМ where М is a consonant with higher sonority than\
+%    K, we are not permitted to hyphenate after М.\
+% 3. In a sequence KBT where K and T are plosives or affricates and B is\
+%    fricative, we separate K from T.\
+% 4. In a sequence CKB where K is a plosive or affricate and C and B are\
+%    fricatives other than в /v/, we separate C from B.\
+% 5. If in a consonant sequence a coronal plosive or affricate Т is\
+%    followed by a labial or dorsal plosive К, then we separate Т from К.\
+% 6. If a consonant sequence contains two plosives or affricates, one\
+%    voiced and one voiceless, then we separate them.\
+% 7. If a consonant sequence contains two fricatives other than в /v/,\
+%    one voiced and one voiceless, then we separate them.\
+% 8. If a consonant sequence contains two labial plosives or two coronal\
+%    plosives or affricates or two dorsal plosives then they are\
+%    separated.\
+% 9. If a consonant sequence contains two equal consonants (not\
+%    necessarily consecutive), then they are separated.\
+% \
+% With so many prohibitive rules, a question arises: if we apply all\
+% these rules, aren't we going to eliminate too many hyphenation\
+% possibilities?  The answer is no.  It can be demonstrated that between\
+% any two consecutive syllables at least one separation point will be\
+% permitted.\

+% \
+% Hyphenation according to the morphology\
+% ---------------------------------------\
+% \
+% Between 1983 and 2012 the official orthographic rules of the\
+% Bulgarian language forbade morphologically based hyphenation.  After\
+% 2012 such hyphenation is permitted (but not obligatory).\
+% \
+% The most important case when it is very desirable to use\
+% morphologically based hyphenation is the case of the compound words.\
+% Divisions such as авток-луб /avtok-lub/ and вакуу-мапарат\
+% /vakuu-maparat/ are extremely irritating even if they are formally\
+% correct.  Unfortunately, we do not have a vocabulary of the compound\
+% Bulgarian words that would permit us to produce rules for automated\
+% hyphenation.  Therefore, the current Bulgarian hyphenation patterns do\
+% not attempt to apply morphological hyphenation to such words.\
+% \
+% Second in importance (but far more significant in terms of numbers) is\
+% the case with the word prefixes.  While the eyes of the reader still\
+% look at the start of the word, the word is still unknown to him.  At\
+% this point, it is very important not to deceive his expectations.  For\
+% example, when the reader sees над- /nad-/ at the end of the line, he\
+% will expect that this is the prefix над- /nad-/ with semantics 'attain\
+% more than'.  This expectation will be fooled if this wasn't really a\
+% prefix, but a deceiving (while formally correct) hyphenation of the\
+% word надремя /nadremya/ 'have dozed enough' where the real prefix is\
+% not над- /nad-/ but на- /na-/ with semantics 'achieve a state after\
+% accumulation'.  Such hyphenation distracts the reader and makes the\
+% reading more difficult.\
+% \
+% Third in importance is the case with the word suffixes.  With respect\
+% to the hyphenation rules we can divide the suffixes into three\
+% categories:\
+% \
+% 1. Suffixes starting with a vowel, for example -ар /-ar/.  It is not\
+%    appropriate to follow the morphology with such suffixes because\
+%    this will contradict the whole hyphenation tradition of the\
+%    Bulgarian language.  For example крав-ар /krav-ar/ is unwarranted.\
+% 2. Suffixes starting with one consonant, for example -ка /-ka/.\
+%    Usually with such suffixes the syllable boundary in the word\
+%    coincides with morpheme boundary so no specific cares are\
+%    necessary, for example кравар-ка /kravar-ka/.  The exceptions are\
+%    rare, for example: обек-тната /obek-tnata/ instead of обект-ната\
+%    /obekt-nata/.\
+% 3. Suffixes starting with more than one consonant (-ски /-ski/, -ство\
+%    /-stvo/).  It is possible to use morphological hyphenation rules\
+%    with such suffixes.\
+% \
+% Even if it is possible to use morphological hyphenation with the\
+% suffixes of the third category, it turns out, this is not as useful as\
+% it is with the case of the prefixes.  When the eyes of the reader have\
+% reached this part of the word, the word is already more or less known\
+% to the reader.  Therefore, at this point the morphological hyphenation\
+% does not provide any significant advantages in comparison to the\
+% simpler hyphenation based only on the syllables in the word.  Consider\
+% for example the word геройс-тво /geroys-tvo/ with suffix -ство\
+% /-stvo/.  When the reader sees геройс- /geroys-/ at the end of the\
+% line this will give him an early clue that the suffix of the word is\
+% -ство /-stvo/.  Such non-morphological hyphenation does not deceive\
+% the expectations of the reader.  On the contrary, it makes the reading\
+% easier because it gives clues to the reader about what follows on the\
+% next line.\
+% \
+% Because of these considerations, the current Bulgarian hyphenation\
+% patterns do not attempt to use morphological hyphenation with respect\
+% to the suffixes of the words.  Though it would be useful to implement\
+% rules about the suffixes of the second cateogory.  Hopefully, some\
+% future version will have such rules.\
+% \
+% Occasionally,[^20] a fourth morphological requirement is stated: that\
+% hyphenation should conform with the boundary between the word and the\
+% definitive articles -та /-ta/ and -те /-te/ (postfixed in Bulgarian).\
+% There is no need to pay attention to this rule because it seems to be\
+% satisfied by its own nature.  The author has searched in a dictionary\
+% with over 860000 Bulgarian words for cases when the hyphenation rules\
+% would hyphenate badly with respect to the definitive article.  He was\
+% unable to find even one such case with the hyphenation rules valid\
+% after 1983 and only about 10 cases with the rules valid before 1983\
+% (one of them is живопи-ста /zhivopi-sta/ instead of живопис-та\
+% /zhivopis-ta/).\
+% \
+% One unavoidable characteristic of any morphologically based automated\
+% hyphenation is that it can create wrong hyphenations.  Because of\
+% this, one useful option is to use the morphology in a safe way – to\
+% use it in order to forbid bad hyphenations but to create no new\
+% hyphenation possibilities solely on the basis of the morphology.\
+% \
+% Take for example the word дозрея /dozreya/ 'ripen fully'.  According\
+% to the phonological rules, we should hyphenate it as доз-рея\
+% /doz-reya/.  According to the morphology, however, we should hyphenate\
+% as до-зрея /do-zreyq/ because this word is formed with the prefix до-\
+% /do-/ with semantics 'complete or supplement' and this semantics would\
+% be lost if the reader sees доз- /doz-/ at the end of the line.\
+% Therefore, there are three methods to hyphenate this word:\
+% \
+% 1. доз-рея /doz-reya/ when morphology is not used;\
+% 2. до-зрея /do-zreya/ when morphology is fully used;\
+% 3. дозрея /dozreya/ (no hyphenation) when morphology is used in a safe\
+%    way.\
+% \
+% The option to use the morphology in a safe way is very attractive when\
+% the software uses a smart line-breaking algorithm which can produce\
+% good results even with less hyphenation possibilities.  TeX is one\
+% such software.  It should be noted that this option does not eliminate\
+% too many hyphenation possibilities because the morpheme boundaries\
+% most of the time are also syllable boundaries.\

+% \
+% The following are results of a statistics about the quality of the\
+% morphological rules (the number after the sign ± is the expected\
+% standard deviation of our estimations):\
+% \
+% With the option `--morphology`:\
+% \
+% * in 0.1% ±0.3% of the dictionary words the morphological patterns\
+%   create very wrong hyphenation;\
+% * in 89.8% ±0.1% of the dictionary words the morphological patterns\
+%   hyphenate identically with the case when no morphology patterns are\
+%   used;\
+% * in 0.3% ±0.2% of the dictionary words the morphological patterns\
+%   hyphenate differently in comparison to the case when no morphology\
+%   patterns are used and the word is hyphenated in a way which\
+%   contradicts the morphology;\
+% * in 0.6% ±0.1% of the dictionary words the morphological patterns\
+%   hyphenate differently in comparison to the case when no morphology\
+%   patterns are used and there is a possible hyphenation which is\
+%   compatible with the word morphology but which is nevertheless\
+%   forbidden by the morphology patterns.\
+%   \
+% With the option `--safe-morphology`:\
+% \
+% * in 0% of the dictionary words the morphological patterns create very\
+%   wrong hyphenation;\
+% * in 90.0% ±0.1% of the dictionary words the morphological patterns\
+%   hyphenate identically with the case when no morphology patterns are\
+%   used;\
+% * in 0.3% ±0.2% of the dictionary words the morphological patterns\
+%   hyphenate differently in comparison to the case when no morphology\
+%   patterns are used and the word is hyphenated in a way which\
+%   contradicts the morphology;\
+% * in 0.6% ±0.1% of the dictionary words the morphological patterns\
+%   hyphenate differently in comparison to the case when no morphology\
+%   patterns are used and there is a possible hyphenation which is\
+%   compatible both with the word morphology and with the syllable\
+%   boundaries but which is nevertheless forbidden by the morphology\
+%   patterns.\
+%   \
+% Notice that the morphological patterns create a different hyphenation\
+% only in about 10% of the words.  The following explanation can be\
+% given for this surprising fact.  First, the natural evolution of the\
+% human languages tends to simplify the complex sequences of consonants.\
+% Therefore, no morpheme contains a complex sequence of consonants.  And\
+% second, the Bulgarian orthography is morphological.  This means that\
+% the morphemes are written according to their actual pronunciation,\
+% however the simplifications in the spoken languages which take place\
+% at the morpheme boundaries are not taken into account in the\
+% orthography.  The independent operation of these two factors leads to\
+% the result that most of the time the morpheme boundaries coincide with\
+% the conventional syllable boundaries.  The main exception to this is\
+% when a morpheme starts with a vowel, in this case its syllable will\
+% include one or more consonants of the preceeding morpheme.  The second\
+% exception is when a morpheme ends with a vowel and the next morpheme\
+% starts with a sequence of two or more consonants.\

+% Usage of the script `hyph-bg.sh`\
+% --------------------------------\
+% \
+% The `hyph-bg.sh` is all-in-one script which can generate both\
+% documentation (this text) and Bulgarian hyphenation patterns.  When\
+% given the option `--help` the script gives short usage instructions:\
+% \
+% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\
+% hyph-bg.sh --help\
+%           Show this info\
+% hyph-bg.sh [--doc-html | --doc-latex | --doc-txt]\
+%           Print documentation in various formats\
+% hyph-bg.sh [other options]\
+%           Generate Bulgarian hyphenation patterns\
+% \
+% Options when generating hyphenation patterns:\
+% \
+%  --standalone-tex\
+%           Produce hyphenation patterns for TeX with \\patterns{ ... }.\
+% \
+%  --no-hyphen-mins\
+%           Hyphenation patterns which do not require hyphen mins.\
+%           Otherwise: both left and right hyphen mins should be set to 2.\
+% \
+%  --safe-dz\
+%           Do not try to guess whether DZ is a single consonant or not.\
+%           Only use hyphenation which will be correct in both cases.\
+% \
+%  --permissible\
+%           Permit any formally correct hyphenation, including unnatural\
+%           divisions, such as studen-tstvo.  Useful for educational tools\
+%           or when typesetting Bulgarian text in a very short column.\
+% \
+%  --morphology\
+%           Apply morphology when hyphenating, for example: za-dvizhvam.\
+%           May hyphenate incorrectly in some cases.\
+% \
+%  --safe-morphology\
+%           Apply morphology when hyphenating.  Never hyphenates incorrectly\
+%           but may prohibit some correct hyphenations.\
+% \
+%  --no-morphology\
+%           Disregard the morphology.  Default.\
+% \
+%  --1945\
+%           Hyphenate according to the rules effective between 1945 and 1982\
+% \
+%  --1983\
+%           Hyphenate according to the rules effective between 1983 and 2011\
+% \
+%  --2012\
+%           Hyphenate according to the rules effective after 2012.  Default.\
+% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\
+% \
+% The following are the recommended ways to generate hyphenation\
+% patterns by this script:\
+% \
+% `hyph-bg.sh --standalone-tex --safe-morphology`\
+% :   For TeX.  Apply the morphology in a safe way when the software\
+%     uses a smart line-breaking algorithm.\
+% \
+% `hyph-bg.sh`\
+% :   For most other software.\
+% \
+% `hyph-bg.sh --no-hyphen-mins`\
+% :   The current versions of Mozilla (as of 2017) seem to ignore the\
+%     hyphen mins in words that contain a dash.\
+% \
+% `hyph-bg.sh --morphology`\
+% :   For professional typography with human proof-reader.\
+% \
+% `hyph-bg.sh --permissible`\
+% :   For educational tools and online dictionaries which can show only one\
+%     kind of hyphenation.\
+% \
+% Notice that some specialised English dictionaries separate the\
+% word-division positions into two categories – preferred positions and\
+% less recommended positions.  It would be best if the Bulgarian online\
+% dictionaries could do the same.  For example hyphen \"-\" can be used to\
+% display the preferred positions and dot \".\" – the less recommended\
+% positions.  If a word-division position is permitted only by the\
+% patterns of `hyph-bg.sh --permissible`, then this position is less\
+% recommended.\
