markdown-it

Rust port of popular markdown-it.js library.

TL;DR:

• if you want to get result fast, use pulldown-cmark
• if you want to render GFM exactly like github, use comrak
• if you want to define your own syntax (like @mentions, :emoji:, custom html classes), use this library

You can check a demo in your browser (it's Rust compiled into WASM).

Features

• 100% CommonMark compatibility
• AST
• Source maps (full support, not just on block tags like cmark)
• Ability to write your own syntax of arbitrary complexity
  • to prove this point, CommonMark syntax itself is written as a plugin

Usage

let parser = &mut markdown_it::MarkdownIt::new();
markdown_it::plugins::cmark::add(parser);
markdown_it::plugins::extra::add(parser);

let ast  = parser.parse("Hello **world**!");
let html = ast.render();

print!("{html}");
// prints "<p>Hello <strong>world</strong>!</p>"

Notes

This is an attempt at making a language-agnostic parser. You can probably parse AsciiDoc, reStructuredText or any other plain text format with this without too much effort. I might eventually write these as proof-of-concept.
