lt3luabridge is an [expl3][1] package for plain TeX, LaTeX, and ConTeXt that
allows you to execute Lua code in LuaTeX or any other TeX engine that exposes
the shell:

``` tex
\documentclass{standalone}
\usepackage{lt3luabridge}
\begin{document}
$ 1 + 2 = \luabridgeExecute{ print(1 + 2) } $
\end{document}
```

lt3luabridge was previously part of [the Markdown package for TeX][2], where it
has been battle-tested since 2016. [Since 2022][3], lt3luabridge has been
available as a separate package.
