Welcome to the LuaTeX wiki
 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 callback, explaining and illustrating it with a couple of examples. The Show the hyphenation points article is another example of use.
- 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!
- You can fake XeTeX's interchar tokens with the token_filter.
- TeX without TeX is about using TeX's functionality (typesetting, pdf writing) only using Lua code (no \TeX macros).
- Create a fontsampler using plain LuaTeX and luaotfload.
- Annotate math expressions in PDF with a bounding box using LuaLaTeX.
