Welcome to the LuaTeX wiki

This is a wiki for LuaTeX, a typesetting engine derived from TeX that includes Lua as an embedded scripting language.

There are two mailing lists related to LuaTeX, one for general discussions and questions about LuaTeX ("luatex users") and one more related to the development of LuaTeX ("dev-luatex")
There is also a LuaLaTeX (LaTeX with LuaTeX) mailing list.
tex.stackexchange.com is a q&a site for questions related to TeX, and you can ask (and answer) LuaTeX related questions there.
The online reference manual (pdf) describes every aspect of LuaTeX, but is rather technical and concise. There also exists a short reference (pdf).

Writing Lua in TeX explains how to write Lua code in a TeX document (and back).
Callbacks introduces callbacks and how to use them.
Show the hyphenation points does what it says; it is also an example of use of the post_linebreak_filter.
The page on the process_input_buffer 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, which lets you enliven your error messages!

(Mostly by and thanks to Yannis Haralambous)

An example of code traversing TeX nodes before an horizontal list goes through the line breaking engine;
An example of code traversing tokens just before execution or expansion;
you want to explore the table obtained from a TrueType font, loaded by font.read_ttf;
you want to explore the internal font table of a pre-loaded font or of a font you have loaded by \font and then used for at least one glyph;
how to use a TrueType font without going through a TFM or a OFM file;
how to do kinsoku (Japanese and more generally CJK typesetting);
you want a newline in your log file or on the terminal? add \string\n to your string;
you want to sort a token list;
you want to split a comma-separated list;
you want to encrypt your document using ROT13;
you want to typeset non-TeX files by converting them using Lua code;
example code to mirror characters with Bidi_Mirrored property;
