Beware that this might break tools like Fontspect that rely on the \fBpatch_font\fP callback provided by Luaotfload to perform important corrections on font data. .sp +The fontloader backend can be selected by setting the value of +\fBfontloader\fP\&. The most important choices are \fBdefault\fP, which will +load the dedicated Luaotfload fontloader, and \fBreference\fP, the +upstream package as shipped with Luaotfload. Other than those, a file +name accessible via kpathsea can be specified. +.sp +Alternatively, the individual files that constitute the fontloader can +be loaded directly. While less efficient, this greatly aids debugging +since error messages will reference the actual line numbers of the +source files and explanatory comments are not stripped. Currently, +three distinct loading strategies are available: \fBunpackaged\fP will +load the batch that is part of Luaotfload. These contain the identical +source code that the reference fontloader has been compiled from. +Another option, \fBcontext\fP will attempt to load the same files by +their names in the Context format from the search path. Consequently +this option allows to use the version of Context that comes with the +TeX distribution. Distros tend to prefer the stable version (“current” +in Context jargon) of those files so certain bugs encountered in the +more bleeding edge Luaotfload can be avoided this way. A third option +is to use \fBcontext\fP with a colon to specify a directory prefix where +the \fITEXMF\fP is located that the files should be loaded from, e. g. +\fBcontext:~/context/tex/texmf\-context\fP\&. This can be used when +referencing another distribution like the Context minimals that is +installed under a different path not indexed by kpathsea. +.sp The value of \fBlog\-level\fP sets the default verbosity of messages printed by Luaotfload. Only messages defined with a verbosity of less than or equal to the supplied value will be output on the terminal. diff --git a/Master/texmf-dist/doc/man/man5/luaotfload.conf.man5.pdf b/Master/texmf-dist/doc/man/man5/luaotfload.conf.man5.pdf deleted file mode 100644 index ed914cc3db1..00000000000 Binary files a/Master/texmf-dist/doc/man/man5/luaotfload.conf.man5.pdf and /dev/null differ diff --git a/Master/texmf-dist/scripts/luaotfload/luaotfload-tool.lua b/Master/texmf-dist/scripts/luaotfload/luaotfload-tool.lua index 8a65298d03a..69b6c976fb1 100755 --- a/Master/texmf-dist/scripts/luaotfload/luaotfload-tool.lua +++ b/Master/texmf-dist/scripts/luaotfload/luaotfload-tool.lua @@ -2,15 +2,13 @@ ----------------------------------------------------------------------- -- FILE: luaotfload-tool.lua -- DESCRIPTION: database functionality --- REQUIREMENTS: luaotfload 2.5 +-- REQUIREMENTS: luaotfload 2.6 -- AUTHOR: Khaled Hosny, Élie Roux, Philipp Gesang --- VERSION: 2.5 -- LICENSE: GPL v2.0 --- MODIFIED: 2014-08-10 23:13:18+0200 ----------------------------------------------------------------------- luaotfload = luaotfload or { } -local version = "2.5-4" --- .- +local version = "2.6" luaotfload.version = version luaotfload.self = "luaotfload-tool" @@ -76,21 +74,13 @@ else -- 5.2 runtime = { "stock", _VERSION } end - local C, Ct, P, S = lpeg.C, lpeg.Ct, lpeg.P, lpeg.S local lpegmatch = lpeg.match -local loader_file = "luatexbase.loader.lua" -local loader_path = assert(kpsefind_file(loader_file, "lua"), - "File '"..loader_file.."' not found") - - string.quoted = string.quoted or function (str) return string.format("%q",str) end -require (loader_path) - --[[doc-- XXX: @@ -109,6 +99,7 @@ config.lualibs.prefer_merged = true config.lualibs.load_extended = true require "lualibs" + local iosavedata = io.savedata local lfsisdir = lfs.isdir local lfsisfile = lfs.isfile @@ -138,22 +129,69 @@ local backup = { } texio.write, texio.write_nl = dummy_function, dummy_function -require"luaotfload-basics-gen.lua" +require "fontloader-basics-gen.lua" texio.write, texio.write_nl = backup.write, backup.write_nl utilities = backup.utilities -require "luaotfload-log.lua" --- this populates the luaotfload.log.* namespace -require "luaotfload-parsers" --- fonts.conf, configuration, and request syntax -require "luaotfload-configuration" --- configuration file handling -require "luaotfload-database" +fonts = { names = { } } -- for db; normally provided by the fontloaders + +local require_init = { } + +local loadmodule = function (name) + local v = require ("luaotfload-" .. name) + if v then + local mod = { } + local tv = type (v) + if tv == "table" then + mod.name = name + mod.init = v.init + require_init [#require_init + 1] = mod + elseif tv == "function" then + mod.name = name + mod.init = v + require_init [#require_init + 1] = mod + end + end +end + require "alt_getopt" -local names = fonts.names -local sanitize_fontname = names.sanitize_fontname +loadmodule "log.lua" --- this populates the luaotfload.log.* namespace +loadmodule "parsers" --- fonts.conf, configuration, and request syntax +loadmodule "configuration" --- configuration file handling +loadmodule "database" +loadmodule "resolvers" --- Font lookup + +local logreport + +local init_modules = function () + --- NB we don’t command the logger at this point. + local todo = #require_init + local ret = true + for i = 1, todo do + local mod = require_init[i] + local name = mod.name + local init = mod.init + if type (init) ~= "function" then + error ("luaotfload broken; module " + .. name ..

Only messages defined with a verbosity of less than or equal to the supplied value will be output on the terminal. diff --git a/Master/texmf-dist/tex/luatex/luaotfload/fontloader-2015-12-09.lua b/Master/texmf-dist/tex/luatex/luaotfload/fontloader-2015-12-09.lua new file mode 100644 index 00000000000..f4181c686c4 --- /dev/null +++ b/Master/texmf-dist/tex/luatex/luaotfload/fontloader-2015-12-09.lua @@ -0,0 +1,11552 @@ +-- merged file : /home/phg/src/latex-dev/luaotfload/src/fontloader/luaotfload-package-merged.lua +-- parent file : /home/phg/src/latex-dev/luaotfload/src/fontloader/luaotfload-package.lua +-- merge date : Wed Dec 9 23:19:38 2015 + +do -- begin closure to overcome local limits and interference + +if not modules then modules={} end modules ['data-con']={ + version=1.100, + comment="companion to luat-lib.mkiv", + author="Hans Hagen, PRAGMA-ADE, Hasselt NL", + copyright="PRAGMA ADE / ConTeXt Development Team", + license="see context related readme files" +} +local format,lower,gsub=string.format,string.lower,string.gsub +local trace_cache=false trackers.register("resolvers.cache",function(v) trace_cache=v end) +local trace_containers=false trackers.register("resolvers.containers",function(v) trace_containers=v end) +local trace_storage=false trackers.register("resolvers.storage",function(v) trace_storage=v end) +containers=containers or {} +local containers=containers +containers.usecache=true +local report_containers=logs.reporter("resolvers","containers") +local allocated={} +local mt={ + __index=function(t,k) + if k=="writable" then + local writable=caches.getwritablepath(t.category,t.subcategory) or { "." } + t.writable=writable + return writable + elseif k=="readables" then + local readables=caches.getreadablepaths(t.category,t.subcategory) or { "." } + t.readables=readables + return readables + end + end, + __storage__=true +} +function containers.define(category,subcategory,version,enabled) + if category and subcategory then + local c=allocated[category] + if not c then + c={} + allocated[category]=c + end + local s=c[subcategory] + if not s then + s={ + category=category, + subcategory=subcategory, + storage={}, + enabled=enabled, + version=version or math.pi, + trace=false, + } + setmetatable(s,mt) + c[subcategory]=s + end + return s + end +end +function containers.is_usable(container,name) + return container.enabled and caches and caches.is_writable(container.writable,name) +end +function containers.is_valid(container,name) + if name and name~="" then + local storage=container.storage[name] + return storage and storage.cache_version==container.version + else + return false + end +end +function containers.read(container,name) + local storage=container.storage + local stored=storage[name] + if not stored and container.enabled and caches and containers.usecache then + stored=caches.loaddata(container.readables,name) + if stored and stored.cache_version==container.version then + if trace_cache or trace_containers then + report_containers("action %a, category %a, name %a","load",container.subcategory,name) + end + else + stored=nil + end + storage[name]=stored + elseif stored then + if trace_cache or trace_containers then + report_containers("action %a, category %a, name %a","reuse",container.subcategory,name) + end + end + return stored +end +function containers.write(container,name,data) + if data then + data.cache_version=container.version + if container.enabled and caches then + local unique,shared=data.unique,data.shared + data.unique,data.shared=nil,nil + caches.savedata(container.writable,name,data) + if trace_cache or trace_containers then + report_containers("action %a, category %a, name %a","save",container.subcategory,name) + end + data.unique,data.shared=unique,shared + end + if trace_cache or trace_containers then + report_containers("action %a, category %a, name %a","store",container.subcategory,name) + end + container.storage[name]=data + end + return data +end +function containers.content(container,name) + return container.storage[name] +end +function containers.cleanname(name) + return (gsub(lower(name),"[^%w\128-\255]+","-")) +end + +end -- closure + +do -- begin closure to overcome local limits and interference + +if not modules then modules={} end modules ['luatex-fonts-nod']={ + version=1.001, + comment="companion to luatex-fonts.lua", + author="Hans Hagen, PRAGMA-ADE, Hasselt NL", + copyright="PRAGMA ADE / ConTeXt Development Team", + license="see context related readme files" +} +if context then + texio.write_nl("fatal error: this module is not for context") + os.exit() +end +if tex.attribute[0]~=0 then + texio.write_nl("log","!") + texio.write_nl("log","!

Once we found ourselves defining similar cache constructs +several times, containers were introduced. Containers are used +to collect tables in memory and reuse them when possible based +on (unique) hashes (to be provided by the calling function).

Caching to disk is disabled by default. Version numbers are +stored in the saved table which makes it possible to change the +table structures without bothering about the disk cache.

Examples of usage can be found in the font related code.

The embedding of a font involves creating temporary files and +depending on your system setup that can fail.

We need to normalize the scale factor (in scaled points). This has to +do with the fact that uses a negative multiple of 1000 as +a signal for a font scaled based on the design size.

Beware, the boundingbox is passed as reference so we may not overwrite it +in the process; numbers are of course copies. Here 65536 equals 1pt. (Due to +excessive memory usage in CJK fonts, we no longer pass the boundingbox.)

The reason why the scaler was originally split, is that for a while we experimented +with a helper function. However, in practice the calls are too slow to +make this profitable and the based variant was just faster. A days +wasted day but an experience richer.

We can prefix a font specification by name: or +file:. The first case will result in a lookup in the +synonym table.

The following function split the font specification into components +and prepares a table that will move along as we proceed.

The main read function either uses a forced reader (as determined by +a lookup) or tries to resolve the name using the list of readers.

We need to cache when possible. We do cache raw tfm data (from , or ). After that we can cache based +on specificstion (name) and size, that is, only needs a number +for an already loaded fonts. However, it may make sense to cache fonts +before they're scaled as well (store 's with applied methods +and features). However, there may be a relation between the size and +features (esp in virtual fonts) so let's not do that now.

So far the specifiers. Now comes the real definer. Here we cache +based on id's. Here we also intercept the virtual font handler. Since +it evolved stepwise I may rewrite this bit (combine code).

This module is a bit more split up that I'd like but since we also want to test +with plain it has to be so. This module is part of +and discussion about improvements and functionality mostly happens on the + mailing list.

+ +

The specification of OpenType is kind of vague. Apart from a lack of a proper +free specifications there's also the problem that Microsoft and Adobe +may have their own interpretation of how and in what order to apply features. +In general the Microsoft website has more detailed specifications and is a +better reference. There is also some information in the FontForge help files.

+ +

Because there is so much possible, fonts might contain bugs and/or be made to +work with certain rederers. These may evolve over time which may have the side +effect that suddenly fonts behave differently.

+ +

After a lot of experiments (mostly by Taco, me and Idris) we're now at yet another +implementation. Of course all errors are mine and of course the code can be +improved. There are quite some optimizations going on here and processing speed +is currently acceptable. Not all functions are implemented yet, often because I +lack the fonts for testing. Many scripts are not yet supported either, but I will +look into them as soon as users ask for it.

+ +

The specification leaves room for interpretation. In case of doubt the microsoft +implementation is the reference as it is the most complete one. As they deal with +lots of scripts and fonts, Kai and Ivo did a lot of testing of the generic code and +their suggestions help improve the code. I'm aware that not all border cases can be +taken care of, unless we accept excessive runtime, and even then the interference +with other mechanisms (like hyphenation) are not trivial.

+ +

Glyphs are indexed not by unicode but in their own way. This is because there is no +relationship with unicode at all, apart from the fact that a font might cover certain +ranges of characters. One character can have multiple shapes. However, at the + end we use unicode so and all extra glyphs are mapped into a private +space. This is needed because we need to access them and has to include +then in the output eventually.

+ +

The raw table as it coms from gets reorganized in to fit out needs. +In that table is packed (similar tables are shared) and cached on disk +so that successive runs can use the optimized table (after loading the table is +unpacked). The flattening code used later is a prelude to an even more compact table +format (and as such it keeps evolving).

+ +

This module is sparsely documented because it is a moving target. The table format +of the reader changes and we experiment a lot with different methods for supporting +features.

+ +

As with the code, we may decide to store more information in the + table.

+ +

Incrementing the version number will force a re-cache. We jump the number by one +when there's a fix in the library or code that +results in different tables.

This chain stuff is somewhat tricky since we can have a sequence of actions to be +applied: single, alternate, multiple or ligature where ligature can be an invalid +one in the sense that it will replace multiple by one but not neccessary one that +looks like the combination (i.e. it is the counterpart of multiple then).

Note: this somewhat +-- complex approach is meant for fonts that implement (for instance) ligatures by character +-- replacement which to some extend is not that suitable for hyphenation.

An example of a \type {luatex.tex} file that is +%D just plain \TEX: +%D +%D \starttyping +%D \catcode`\{=1 % left brace is begin-group character +%D \catcode`\}=2 % right brace is end-group character +%D +%D \input plain +%D +%D \everyjob\expandafter{\the\everyjob\input luatex-fonts\relax} +%D +%D \dump +%D \stoptyping +%D +%D We could load the \LUA\ file in \type {\everyjob} but maybe some +%D day we need more here. +%D +%D When defining a font you can use two prefixes. A \type {file:} +%D prefix forced a file search, while a \type {name:} prefix will +%D result in consulting the names database. Such a database can be +%D generated with: +%D +%D \starttyping +%D mtxrun --usekpse --script fonts --names +%D \stoptyping +%D +%D This will generate a file \type {luatex-fonts-names.lua} that has +%D to be placed in a location where it can be found by \KPSE. Beware: +%D the \type {--kpseonly} flag is only used outside \CONTEXT\ and +%D provides very limited functionality, just enough for this task. +%D +%D The code loaded here does not come out of thin air, but is mostly +%D shared with \CONTEXT, however, in that macropackage we go beyond +%D what is provided here. When you use the code packaged here you +%D need to keep a few things in mind: +%D +%D \startitemize +%D +%D \item This subsystem will be extended, improved etc. in about the +%D same pace as \CONTEXT\ \MKIV. However, because \CONTEXT\ provides a +%D rather high level of integration not all features will be supported +%D in the same quality. Use \CONTEXT\ if you want more goodies. +%D +%D \item There is no official \API\ yet, which means that using +%D functions implemented here is at your own risk, in the sense that +%D names and namespaces might change. There will be a minimal \API\ +%D defined once \LUATEX\ version 1.0 is out. Instead of patching the +%D files it's better to overload functions if needed. +%D +%D \item The modules are not stripped too much, which makes it +%D possible to benefit from improvements in the code that take place +%D in the perspective of \CONTEXT\ development. They might be split a +%D bit more in due time so the baseline might become smaller. +%D +%D \item The code is maintained and tested by the \CONTEXT\ +%D development team. As such it might be better suited for this macro +%D package and integration in other systems might demand some +%D additional wrapping. Problems can be reported to the team but as we +%D use \CONTEXT\ \MKIV\ as baseline, you'd better check if the problem +%D is a general \CONTEXT\ problem too. +%D +%D \item The more high level support for features that is provided in +%D \CONTEXT\ is not part of the code loaded here as it makes no sense +%D elsewhere. Some experimental features are not part of this code +%D either but some might show up later. +%D +%D \item Math font support will be added but only in its basic form +%D once that the Latin Modern and \TEX\ Gyre math fonts are +%D available. +%D +%D \item At this moment the more nifty speed-ups are not enabled +%D because they work in tandem with the alternative file handling +%D that \CONTEXT\ uses. Maybe around \LUATEX\ 1.0 we will bring some +%D speedup into this code too (if it pays off at all). +%D +%D \item The code defines a few global tables. If this code is used +%D in a larger perspective then you can best make sure that no +%D conflicts occur. The \CONTEXT\ package expects users to work in +%D their own namespace (\type {userdata}, \type {thirddata}, \type +%D {moduledata} or \type {document}. The team takes all freedom to +%D use any table at the global level but will not use tables that are +%D named after macro packages. Later the \CONTEXT\ might operate in +%D a more controlled namespace but it has a low priority. +%D +%D \item There is some tracing code present but this is not enabled +%D and not supported outside \CONTEXT\ either as it integrates quite +%D tightly into \CONTEXT. In case of problems you can use \CONTEXT\ +%D for tracking down problems. +%D +%D \item Patching the code in distributions is dangerous as it might +%D fix your problem but introduce new ones for \CONTEXT. So, best keep +%D the original code as it is. +%D +%D \item Attributes are (automatically) taken from the range 127-255 so +%D you'd best not use these yourself. +%D +%D \stopitemize +%D +%D If this all sounds a bit tricky, keep in mind that it makes no sense +%D for us to maintain multiple code bases and we happen to use \CONTEXT. +%D +%D For more details about how the font subsystem works we refer to +%D publications in \TEX\ related journals, the \CONTEXT\ documentation, +%D and the \CONTEXT\ wiki. + +\directlua { + if not fonts then + dofile(kpse.find_file("luatex-fonts.lua","tex")) +

We create a namespace and some variables to it. If a namespace is + already defined it wil not be initialized. This permits hooking + in code beforehand.

We don't make a format automatically. After all, distributions + might have their own preferences and normally a format (mem) file will + have some special place in the tree. Also, there can already + be format files, different memort settings and other nasty pitfalls that + we don't want to interfere with. If you want, you can define a function + metapost.make(name,mem_name) that does the job.

Interesting is that compared to the built-in this is faster in +-- luatex than in luajittex where we have a comparable speed.

Each formatter +-- is a function so there is some overhead and not all formatted output is worth that +-- overhead. Keep in mind that there is an extra function call involved. In principle +-- we end up with a string concatination so one could inline such a sequence but often +-- at the cost of less readabinity. So, it's a sort of (visual) compromise. Of course +-- there is the benefit of more variants. (Concerning the speed: a simple format like +-- %05fpt is better off with format than with a formatter, but as soon as you put +-- something in front formatters become faster. Passing the pt as extra argument makes +-- formatters behave better. Of course this is rather implementation dependent.

This module is a bit more split up that I'd like but since we also want to test -with plain it has to be so. This module is part of -and discussion about improvements and functionality mostly happens on the - mailing list.

- -

The specification of OpenType is kind of vague. Apart from a lack of a proper -free specifications there's also the problem that Microsoft and Adobe -may have their own interpretation of how and in what order to apply features. -In general the Microsoft website has more detailed specifications and is a -better reference. There is also some information in the FontForge help files.

- -

Because there is so much possible, fonts might contain bugs and/or be made to -work with certain rederers. These may evolve over time which may have the side -effect that suddenly fonts behave differently.

- -

After a lot of experiments (mostly by Taco, me and Idris) we're now at yet another -implementation. Of course all errors are mine and of course the code can be -improved. There are quite some optimizations going on here and processing speed -is currently acceptable. Not all functions are implemented yet, often because I -lack the fonts for testing. Many scripts are not yet supported either, but I will -look into them as soon as users ask for it.

- -

Because there are different interpretations possible, I will extend the code -with more (configureable) variants. I can also add hooks for users so that they can -write their own extensions.

- -

Glyphs are indexed not by unicode but in their own way. This is because there is no -relationship with unicode at all, apart from the fact that a font might cover certain -ranges of characters. One character can have multiple shapes. However, at the - end we use unicode so and all extra glyphs are mapped into a private -space. This is needed because we need to access them and has to include -then in the output eventually.

- -

The raw table as it coms from gets reorganized in to fit out needs. -In that table is packed (similar tables are shared) and cached on disk -so that successive runs can use the optimized table (after loading the table is -unpacked). The flattening code used later is a prelude to an even more compact table -format (and as such it keeps evolving).

- -

This module is sparsely documented because it is a moving target. The table format -of the reader changes and we experiment a lot with different methods for supporting -features.

- -

As with the code, we may decide to store more information in the - table.

- -

Incrementing the version number will force a re-cache. We jump the number by one -when there's a fix in the library or code that -results in different tables.

This chain stuff is somewhat tricky since we can have a sequence of actions to be -applied: single, alternate, multiple or ligature where ligature can be an invalid -one in the sense that it will replace multiple by one but not neccessary one that -looks like the combination (i.e. it is the counterpart of multiple then). For -example, the following is valid:

- - -xxxabcdexxx [single a->A][multiple b->BCD][ligature cde->E] xxxABCDExxx - - -

Therefore we we don't really do the replacement here already unless we have the -single lookup case. The efficiency of the replacements can be improved by deleting -as less as needed but that would also make the code even more messy.
