Lezer: A Parsing System for CodeMirror, Inspired by Tree-Sitter

1. import-tree-sitter

   1 1 27 - TypeScript

   Helps import tree-sitter grammars

   

   On one hand, it’s a nice framework. I customized the Typescript one a bunch for a lil side project and enjoyed myself. On the other hand, it would be great if CodeMirror could just work with Tree-sitter. There’s a lot of ececosystem around other parsing systems, and needing to figure out Lezer stuff is a big friction for adopting CodeMirror 6 for me. There are not a lot of language packages listed: https://codemirror.net/docs/community/

   There’s a kind of importer thingy here but it doesn’t work well for complex grammars: https://github.com/lezer-parser/import-tree-sitter

3. lezer

   2 3 36 4.6 JavaScript

   Dev utils and issues for the Lezer core packages

   

   I attempted to use this but was disheartened but the fact that it doesn't statically type node names. Tree Sitter doesn't either but it has much more of an excuse given that it targets C.

   https://github.com/lezer-parser/lezer/issues/8

   The dev seems mildly hostile to outside involvement too, so I moved on. These days I use Chumsky which is Rust rather than Typescript, but also way more awesome, if you can deal with the often incomprehensible compilation errors at least!

5. tree-sitter

   4 72 21,287 9.8 Rust

   An incremental parsing system for programming tools

   

   I learned from a google search that these days upstream tree-sitter provides WebAssembly bindings.

   Source: https://github.com/tree-sitter/tree-sitter/tree/master/lib/b...

   NPM: https://www.npmjs.com/package/web-tree-sitter

   Download from the latest Github release: js file (https://github.com/tree-sitter/tree-sitter/releases/download...) and wasm file (https://github.com/tree-sitter/tree-sitter/releases/download...)

6. yaade

   5 5 1,778 8.5 JavaScript

   Yaade is an open-source, self-hosted, collaborative API development environment.

   

   I've been using both codemirror and lezer in Yaade (https://github.com/EsperoTech/yaade). Thanks to lezer I was able to write a JSON extension language that supports Yaade environment variables. Pretty cool project and very nicely documented! I love building OSS on top of OSS.

7. codemirror-elements

   6 1 48 6.5 TypeScript

   A set of CodeMirror custom HTML elements

   

   I have a project that's intended to make Code Mirror 6 as ready to use as any HTML tag: https://github.com/justinfagnani/codemirror-elements

   You can put a basic code editor on your page like:

8. code-mirror-custom-element

   7 1 4 3.7 JavaScript

   CodeMirror 6 as a custom element (web component)

   

   Not as extensive as the previous poster. I wrote a small custom component wrapper a while back: https://github.com/flawiddsouza/code-mirror-custom-element.

10. generator

    8 1 176 4.3 TypeScript

    Parser generator for the lezer incremental parser (by lezer-parser)

    

    Yes it's unsolicited "advice" that shows an uncooperative attitude IMO. You can say "I don't want to do that" in a nice way without being patronising. If you look at the other closed MRs you'll see a similar attitude.

    E.g. here (I'd forgotten about this actually): https://github.com/lezer-parser/generator/pull/6#issuecommen...

    Here https://github.com/lezer-parser/lr/pull/64#issuecomment-1802...

    It's nothing major but just emanates "difficult to work with" vibes so I didn't want to spend my time working with a project like that (looks like not many other people do either).
