Documentation and help

Documentation

• The definitive source of information on LuaTeX is the LuaTeX Reference; the link points to the latest version, documenting latest builds, but can be used for older versions too.

• The previous document reduced to a cheatsheet is also available with the Short Reference.

• Besides general information, the LuaTeX site also hosts some presentations by members of the team.

• TUGboat (communications of the TeX User Group) has featured regular articles on LuaTeX for some years now.

• More can be found in publications by local user groups and conferences.

Help

• The LuaTeX mailing list is frequented by knowledgeable people and questions rarely remain unanswered.

• There is also a list for developers for very technical things.

• Questions about LuaTeX can also be asked in other TeX-related lists or sites: texhax, comp.text.tex (and similar groups for different languages), or TeX StackExchange.

On Lua

• The main source on the Lua language is the Lua reference manual; the link here documents version 5.2, currently used by LuaTeX, but Lua 5.1 is what LuaTeX used up to v0.74; see the Lua 5.1 reference manual if necessary. See also the changes and incompatibilities.

• Programming in Lua, by Lua's chief architect Roberto Ierusalimschy, is available online for version 5.0, quite usable for later versions.

• There is also a mailing list and a forum.

• All this and more can be found on the Lua website.
