# markdown-it [](https://markdown-it-rust.github.io/markdown-it/) [](https://github.com/markdown-it-rust/markdown-it) [](https://docs.rs/markdown-it) [](https://crates.io/crates/markdown-it) [](https://app.codecov.io/gh/markdown-it-rust/markdown-it) Rust port of popular [markdown-it.js](https://github.com/markdown-it/markdown-it) library. TL;DR: - if you want to get result *fast*, use [pulldown-cmark](https://github.com/raphlinus/pulldown-cmark) - if you want to render GFM exactly like github, use [comrak](https://github.com/kivikakk/comrak) - if you want to define your own syntax (like `@mentions`, `:emoji:`, custom html classes), use this library You can check a [demo](https://markdown-it-rust.github.io/markdown-it/) 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 ```rust 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 "
Hello world!
" ``` For a guide on how to extend it, see `examples` folder. ### Notes *This is an attempt at making a language-agnostic parser. You can probably parse AsciiDoc, reStructuredText or [any other](https://github.com/mundimark/awesome-markdown-alternatives) plain text format with this without too much effort. I might eventually write these as proof-of-concept.*
