%% This is part of the OpTeX project, see http://petr.olsak.net/optex
% This file is read from optex-doc.tex
% Use: optex optex-doc
% (three times) to create whole documentation including all references and the index.
\load [doc.opm]
\thisoutline {TECHNICAL DOCUMENTATION}
\chap Technical documentation
This documentation is written in the source files `*.opm` between
the `\_doc` and `\_cod` pairs or after the `\_endcode` command.
When the format is generated by
\begtt
luatex -ini optex.ini
\endtt
then the text of the documentation is ignored and the format `optex.fmt` is
generated. On the other hand, if you run
\begtt
optex optex-doc.tex
\endtt
then the same `*.opm` files are read when the second chapter of this
documentation is printed.
A knowledge about \TeX/ is expected from the reader.
You can see a short document
\ulink[http://petr.olsak.net/ftp/olsak/optex/tex-nutshell.pdf]{\TeX/ in a Nutshell}
or more detail
\ulink[https://eijkhout.net/texbytopic/texbytopic.html]{\TeX/ by topic}.
Notices about hyperlinks.
If a control sequence is printed in red color in this documentation then
this denotes its \"main documentation point". Typically, the listing where
the control sequence is declared follows immediately. If a control sequence is
printed in the blue color in the listing or in the text
then it is an active link that points (usually) to the main documentation point.
The main documentation point can be an active link that points to a previous
text where the control sequence was
mentioned. Such occurrences are active links to the main documentation point.
\sec[init] The main initialization file
The `optex.ini` file is read as the main file when the format is generated.
{\everytt={\typosize[8/10]\_let\_printverbline=\_printcodeline \medskip}
\def\docfile{optex.ini}
\verbinput (-4) optex.ini
%
Category codes are set first. Note that the `_` is set to category code
\"letter", it can be used as a part of control sequence names.
Other category codes are set as in plain \TeX/.
\verbinput (6-20) optex.ini
%
The \`\optexversion` and \`\fmtname` are defined.
\verbinput (22-26) optex.ini
%
We check if \LuaTeX/ engine is used at `-ini` state. And the `^^J` character
is set as `\newlinechar`.
\verbinput (28-37) optex.ini
%
The basic macros for macro file syntax is defined, i.\,e.\
`\_endcode`, `\_doc` and `\_cod`.
The `\_codedecl` will be re-defined later.
\verbinput (39-43) optex.ini
%
Individual `*.opm` macro files are read.
\verbinput (45-89) optex.ini
%
The file `optex.lua` is embedded into the format as byte-code.
It is documented in section~\ref[lua].
\verbinput (91-94) optex.ini
The `\everyjob` register is initialized and the format is saved by
the `\dump` command.
\verbinput (96-104) optex.ini

\sec[lua] Lua code embedded to the format
The file `optex.lua` is loaded into the format in `optex.ini` as byte-code
and initialized by `\everyjob`, see section~\ref[init].
The file implements part of the functionality from `luatexbase` namespace,
nowadays defined by \LaTeX/ kernel. `luatexbase` deals with modules,
allocators, and callback management. Callback management is a nice extension
and is actually used in \OpTeX/. Other functions are defined more or less just
to suit luaotfload's use.
The allocations are declared in subsection~\ref[lua-alloc], calbacks are
implemented in subsection~\ref[callbacks] and handling with colors can be
found in the subsection~\ref[lua-colors].
