This is an attempt to implement automatic conversion of LuaLaTeX inline and display math expressions into MathML code to aid with tagging.
It works best with unicode-math, but it can also be used with traditional math fonts if mappings to Unicode are provided.
Run l3build install to install luamml into your local texmf tree.
To generate MathML of your LuaLaTeX formulas you should use latex-lab-math which will internally call LuaMML. A typical example would be
\DocumentMetadata{lang=en, tagging=on, tagging-setup={math/setup=mathml-SE}}
\documentclass{article}
\usepackage{unicode-math}
\begin{document}
\[ E=mc^2 \]
\end{document}
This will automatically generate MathML nd embed it into the tagging structure of the output. See the latex-lab-math documentation for details.
