latex-parser v0.6.2

JavaScript LaTeX parser

Live demo in browser

This is a library designed to build abstract syntax trees for LaTeX documents using JavaScript / TypeScript.

⚠ Warning

This project only parses a subset of what can be considered "canonical" LaTeX. As I see it, a full LaTeX parser would be a complete port of the TeX code, and I am not crazy enough to attempt that. Of course, we can still make something that works most of the time. This approach is similar to KaTeX, a Javascript library which focuses on math typesetting. This library focuses more on parsing text mode.

If you don't believe parsing LaTeX is necessarily difficult, prepare to be outsmugged:

• Is there a BNF grammar of the TeX language?
• Full LaTeX parser in Java
• Why is LaTeX so complicated?

Usage

Download the latest standalone JavaScript file (ES5) or install from NPM:

npm install latex-parser

import {latexParser} from "latex-parser";

// tokens :: LaTeX[]
const tokens = latexParser.parse("hello \\author[opt]{name}");

History on project

This project used to be a TypeScript fork of the TeXnous project, but after v0.3.0 is modeled after the Haskell LaTeX library HaTeX.
