Is there a project that takes tree-sitter grammars and parses them without like skipping over the 40 megabytes of C code generated? I think for some use cases, you might want to care more about bundle size than you would care about runtime performance.

Is there anything in particular you'd like to be able to hook into / customize?
If you don't mind using something that's kinda early, absolutely shameful ad, but perhaps you'd like maudit.org since it was built (partly) due to frustration with that exact problem

stupid idea: lib.rs/crates/typenum but for grammars so you can do compile-time parsing?
typenum
Typenum is a Rust library for type-level numbers evaluated at compile time. It currently supports bits, unsigned integers, and signed integers. It also provides a type-level array of type-level numbers, but its implementation is incomplete.

I'm continuously impressed with how just how good the Rust ecosystem is. Whenever I look for a crate or a CLI utility that does what I want, 95% of the time I find it.
And the rest of the time, the components are right there for me to build it.

But the last update was 4-5 years ago, so... it was time to port (some of it) to Rust:

Who do I talk to about adding more syntax highlighting grammars for docs.rs ? Because it does not even support JSON. I mean, I wanted to add KDL, but JSON's up first!
