LaTeX to Typst
Convert LaTeX mathematics to Typst with the structure intact.

A document converter has to preserve what the mathematics means as well as how it looks. Fractions, matrices, and sums put that problem in front of you: the source, converted structure, and rendered result all have to agree. My Tylax work focuses on those semantics and on the package behavior around them.
Progress
My local fork covers semantic conversion, package contracts, parser expansion, and validation. Three native conversions appear below with Typst previews. Their reports mark the artifacts Degraded because amsmath has no active handler. That package diagnostic is the next fix.
Follow the mathematics into Typst
Choose a fraction, matrix, or sum and compare its LaTeX source, converted Typst, and preview.
From LaTeX source to Typst output
The source becomes a Typst document with a rendered preview. Tylax reports Degraded because amsmath has no active handler, even though the converted math compiles.
- Converter
- Tylax 0.3.6
- Artifact grade
- Degraded
- Preview compiler
- Typst 0.15.1
Input
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[\frac{a}{b} + \sqrt{x}\]
\end{document}
Result
#set text(font: "New Computer Modern", size: 10pt)
#set par(leading: 2pt)
$ frac(a, b)+sqrt(x) $

The native Rust converter produces the recorded output, and Typst 0.15.1 renders the preview. The artifact grade identifies the amsmath handler to fix next. SciPenAI authors Tylax.

Add the amsmath handler and compare the converted documents with the converter's target compiler.

How does the converted structure preserve the original mathematics?
Three native Tylax conversions pair LaTeX source with Typst output, previews, and the converter artifact grade.
Compare the source, converted text, and preview for a fraction, matrix, and sum.
The native Rust converter produces the Typst output. Typst renders the SVG previews.
