LuaTeX is a TeX-based computer typesetting system which started as a version of pdfTeX with a Lua scripting engine embedded. After some experiments it was adopted by the pdfTeX team as a successor to pdfTeX (itself an extension of eTeX, which generates PDFs). Later in the project some functionality of Aleph was included (esp. multi-directional typesetting). The project was originally sponsored by the Oriental TeX project, founded by Idris Samawi Hamid, Hans Hagen, and Taco Hoekwater.
Objective of the project
The main objective of the project is to provide a version of TeX where all internals are accessible from Lua. In the process of opening up TeX much of the internal code is rewritten. Instead of hard coding new features in TeX itself, users (or macro package writers) can write their own extensions. LuaTeX offers native support for OpenType fonts. In contrast to XeTeX, the fonts are not accessed through the operating system libraries, but through a library based on FontForge.
The LuaTeX team consists of Taco Hoekwater, Hartmut Henkel and Hans Hagen.
The first public beta was launched at TUG 2007 in San Diego. The first formal release was planned for the end of 2009, and the first stable production version was released in 2010. It was expected to reach version 1.00 in 2012 but as of October 2015[update] it is expected to be released with TeX Live 2020.
As of October 2010[update], both ConTeXt mark IV and LaTeX with extra packages (e.g. luaotfload, luamplib, luatexbase, luatextra) make use of new LuaTeX features. Both are supported in TeX Live 2010 with LuaTeX 0.60. Special support in plain TeX is still under development.
