Show HN: Tylax – A bidirectional LaTeX to Typst converter in Rust

Hi HN, author here.

I built Tylax because I wanted to migrate my old LaTeX papers to Typst but found existing regex-based scripts too fragile for nested environments.

Tylax parses LaTeX into an AST (using mitex-parser) and converts it to Typst code. It supports: - Full document structure (not just math snippets) - Complex math (matrices, integrals) - Experimental TikZ -> CeTZ graphics conversion - Runs in browser via WASM

Happy to answer any questions!

nice job! so i tried around and so far am impressed, anyhow:

\newcommand{\foo}[1]{\bar{#1}} \renewcommand{\bar}[1]{\foo{#1}} % mutual recursion \foo{x} \def\x{\y}\def\y{z}\x % chained expansion

#set page(paper: "a4") #set heading(numbering: "1.") #set math.equation(numbering: "(1)") /* \foo / / \y /

\foo{x} → \bar{x} → \foo{x} → ∞ Expected: hit depth limit, emit warning, output either x or the unexpanded \foo{x} Actual: / \foo */ — silently converted to a comment, lost the argument x entirely

Could you briefly explain why Pandoc was not sufficient? (Obviously it can’t do the TikZ -> CeTZ conversion.)
