Josef Friedrich: /* Useful modules */ add nodetree package

== Welcome to the LuaTeX wiki ==

This is a wiki for [http://www.luatex.org LuaTeX], a typesetting engine derived from
[http://en.wikipedia.org/wiki/TeX TeX] that includes [http://www.lua.org Lua] as an embedded scripting language.

See [[Special:Allpages|all the articles]] or the [[Special:Recentchanges|recent changes]].

* [http://www.mediawiki.org/wiki/Help:Formatting How to edit wiki pages]
* [[Bug tracking|Bug tracking]]: Mantis [http://tracker.luatex.org bug tracker]

== Some articles ==

* [[Documentation and help]] points to other online resources (manuals, mailing list, etc.) related to LuaTeX.
* [[Writing Lua in TeX]] explains how to write Lua code in a TeX document (and back).
* [[Attributes]] introduces LuaTeX's thrilling new concept.
* Pages on callbacks:
** [[Callbacks]] introduces callbacks and how to use them.
** There is a page on the [[Post linebreak filter|<tt>post_linebreak_filter</tt>]] callback, explaining and illustrating it with a couple of examples. The [[Show the hyphenation points]] article is another example of use.
** The page on [[process input buffer|the <tt>process_input_buffer</tt> callback]] illustrates how to read documents with non-UTF-8 encoding, and how to write TeX with lightweight markup instead of the usual commands.
** Another callback is [[show error hook|<tt>show_error_hook</tt>]], which lets you enliven your error messages!
** You can fake XeTeX's interchar tokens with the [[token filter|<tt>token_filter</tt>]].
* [[TeX without TeX]] is about using TeX's functionality (typesetting, pdf writing) only using Lua code (no <tt>\TeX</tt> macros).
* [[fontsampler|Create a fontsampler]] using plain LuaTeX and <tt>luaotfload</tt>.
* [[Annotate math expressions]] in PDF with a bounding box using LuaLaTeX.
