Should support all syntax in the existing rust compiler. (except WSA)
https://github.com/faldor20/tree-sitter-roc
For those testing the new compiler, I got a bit ahead and implemented the new syntax here:
https://github.com/roc-lang/roc/issues/7106
You can find that version here:
https://github.com/faldor20/tree-sitter-roc/tree/new-syntax
Something I spent quite a while making work was being able to color effectful and shadowable idents:
(identifier "!")@ident.effectful
(identifier "_")@ident.shadowable
It parses the "!" and "_" separate, so we can then query only effectful/shadowable idents

Anthony Bullard (Mar 10 2025 at 13:43):Thank you for your hard work Eli, especially on the new syntax support!
Anthony Bullard (Mar 10 2025 at 13:45):I wonder selfishly how hard it would be to create a .snapshot.roc grammar that has embeds for the new Roc grammar and the SExpr syntax (as just Scheme or basic LISP) in our snapshot files
Anthony Bullard (Mar 10 2025 at 13:46):And also treat the section dividers as comments (with maybe some highlighting for the section header text
Eli Dowling (Mar 10 2025 at 13:46):Not hard at all! Embeds are super easy. If you make a discussion with some syntax examples I can offer advice or if it's simple just do it this arvy
Anthony Bullard (Mar 10 2025 at 13:53):Cool, yeah I'll probably take a shot at it sometime soon
Anthony Bullard (Mar 10 2025 at 13:53):It'll be great for snapshots to be easy to read unlike our old snapshots
Eli Dowling (Mar 10 2025 at 15:49):I just made an update to the syntax to fix some issues @JanCVanB noticed.
