'''LuaTeX''' is a [[TeX]]-based computer [[typesetting]] system which started as a version of [[pdfTeX]] with a [[Lua (programming language)|Lua]] scripting engine embedded. After some experiments it was adopted by the [[TeX Live]] distribution as a successor to pdfTeX (itself an extension of [[ε-TeX]], which generates [[PDF]]s).<ref>[http://www.tex.ac.uk/cgi-bin/texfaq2html?label=whatpdftex TeX Frequently Asked Questions] {{Webarchive|url=https://web.archive.org/web/20141027085637/http://www.tex.ac.uk/cgi-bin/texfaq2html?label=whatpdftex |date=2014-10-27 }} - What is PDFTeX?</ref><ref>[http://www.tex.ac.uk/cgi-bin/texfaq2html?label=luatex TeX Frequently Asked Questions] {{Webarchive|url=https://web.archive.org/web/20141027023550/http://www.tex.ac.uk/cgi-bin/texfaq2html?label=luatex |date=2014-10-27 }} - PDFTeX and LuaTeX</ref><ref>[https://www.tug.org/applications/pdftex/NEWS PDFTeX's NEWS file] {{webarchive|url=http://arquivo.pt/wayback/20090709061627/http://www.tug.org/applications/pdftex/NEWS|date=2009-07-09}} - news for 3.141592-1.40.0 version.</ref> Later in the project some functionality of [[Aleph (TeX)|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.

In November 2024, LuaLaTeX was declared the recommended format for [[LaTeX]].<ref name="LuaLaTeX">[https://www.texdev.net/2024/11/05/engine-news-from-the-latex-project Engine news from the LaTeX Project]</ref>

==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 support for [[OpenType]] fonts with external modules. One of them, written in Lua, is provided by the LuaTeX team, but support for complex scripts is limited. Since 2020 LuaTeX includes the HarfBuzz engine for correct rendering of complex scripts using OpenType.<ref name='harfbuzz'>{{cite web | url=https://tug.org/TUGboat/tb40-1/tb124hosny-harfbuzz.pdf | title=Bringing world scripts to LuaTEX: The HarfBuzz experiment | author=Khaled Hosny | access-date=2023-07-14 }}</ref>
An alternate approach can be found on GitHub.<ref name="Harf">{{cite web |last1=tatzetwerk |title=luatex-harfbuzz |url=https://github.com/tatzetwerk/luatex-harfbuzz |website=GitHub |date=August 2020 |access-date=16 October 2021}}</ref>

A related project is [[MPLib]] (an extended [[MetaPost]] library module), which brings a graphics engine into TeX.<ref name="MPLib">{{cite journal |last1=Hagen |first1=Hans |title=The MetaPost library and LuaTEX |journal=TUGboat - TUG 2008 Conference Proceedings |volume=29 |issue=3 |pages=446–453 |url=https://www.tug.org/TUGboat/tb29-3/tb93hagen-mplib.pdf |access-date=16 October 2021}}</ref>

The LuaTeX team consists of Luigi Scarso, Taco Hoekwater, Hartmut Henkel and Hans Hagen.

==Versions==
The first public beta was launched at [[TeX Users Group|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. Version 1.00 was released in September 2016 during ConTeXt 2016. Version 1.12 was released for TeXLive 2020.<ref name="roadmap">{{cite web |url=http://www.luatex.org/roadmap.html |title=LuaTeX Roadmap |work=luatex.org |access-date=2023-07-14}}</ref>

{{As of|2010|10}}, both [[ConTeXt]] mark IV and [[LaTeX]] with extra packages (e.g. luaotfload, luamplib, luatexbase, luatextra) make use of new LuaTeX features. (When LuaTeX is used with the LaTeX format, it is sometimes called "LuaLaTeX".) Both are supported in [[TeX Live]] 2010 with LuaTeX 0.60, and in [[LyX]].<ref>{{Cite web|url=https://wiki.lyx.org/LyX/LuaTeX|title=LyX wiki {{!}} LyX / LuaTeX|website=wiki.lyx.org|access-date=2017-08-31}}</ref> Special support in plain TeX is still under development.

Further development takes place as ''LuaMetaTeX'' in connection with the [[ConTeXt]] project.<ref name="roadmap"/><ref>{{cite web |url=https://github.com/contextgarden/luametatex |title=luametatex |work=GitHub |access-date=2023-07-14}}</ref>
