Project mention: Lezer: A Parsing System for CodeMirror, Inspired by Tree-Sitter | news.ycombinator.com | 2024-03-24I 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...)
Would you consider using some libraries in your project? There are lots of good ones in the Rust ecosystem, and many of them are not part of any existing browsers.
For example:
- https://github.com/servo/html5ever (HTML parsing - note: this is used in Servo)
- https://github.com/parcel-bundler/lightningcss (CSS parsing)
- https://github.com/DioxusLabs/taffy (web layout)
- https://github.com/pop-os/cosmic-text (text layout and rendering)
Obviously you should be free to work on whatever you like, but just as a benchmark on the scope of your project: I spent ~6 months implementing just the CSS Grid algorithm in Taffy last year. An entire browser from literal scratch is probably a 10 year project for one person.

Project mention: Lezer: A Parsing System for CodeMirror, Inspired by Tree-Sitter | news.ycombinator.com | 2024-03-24I 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.

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!

This is mighty impressive! I've been trying to get some motivation for the mythical rewrite of the proc macro in Logos, and this might just do it for me :D. I'll have a proper look later today and see if any of your findings have something that can be generalized. Also really surprised to see aarch64 doing better than x86_64 since the latter is what I've been optimizing for!
