tex2typst

JavaScript library for converting TeX / LaTeX math formula code to Typst

Try it online

A Web UI wrapper is available at https://qwinsi.github.io/tex2typst-webapp/.

Installation

npm install tex2typst

Usage

Basic usage

import { parseTex, tex2typst } from 'tex2typst';

let output = tex2typst("\\zeta(s) = \\sum_{n=1}^{\\infty}\\frac{1}{n^s}");
console.log(output);
// zeta(s) = sum_(n = 1)^infinity frac(1, n^s)

Advanced settings

• custom TeX macros/commands

For example,

let macros = {
    "\\sgn": "\\operatorname{sgn}"
};
let input = "y = \\sgn(x)";
const output = tex2typst(input, {customTexMacros: macros});
console.log(output);
// y = op("sgn")(x)

How it works

graph LR
    tex[TeX code] --parser--> ast[TeX AST] --writer--> typst[Typst code]

• parser: Implemented in function parseTex(). At present, it depends on the parser implemented by KaTeX.
• writer: Implemented in class TypstWriter()
