langs-in-rust VS chumsky

Gleam is written in Rust and is a nice example (besides Rust itself) of what it looks like to write a language in Rust. By my own tracking (https://github.com/alilleybrinker/langs-in-rust) Gleam is one of the most popular languages written in Rust and is one of the few top languages in that list which isn't a reimplementation of an existing language!

Ah yes, std, that famous crate that is unusable for systems programming. God forbid anyone do any "systems" programming that uses std.

A scripting language with an interpreter written in rust? Lua doesn't compile to C. The Lua interpreter is written in C and can inter-operate with it. Maybe look here: https://github.com/alilleybrinker/langs-in-rust

There are in fact! If I remember correctly, Gluon and Gleam are both done via Combinators. You can probably find many more here

Or maybe see languages implemented in Rust being writen in rust doesn't mean they're good at interacting wirh rust)

Parcel has been added to my list of languages implemented in Rust! It's currently the only CSS implementation listed there.

For anyone interested in languages written in Rust, here’s a list: https://github.com/alilleybrinker/langs-in-rust

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.

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!

We are using technique called parser combinator. And we are using a library chumsky to write parser combinators.

rust-langdev has a lot of libraries for building compilers in Rust. Perhaps you could use these to make your implementation easier, and revisit it later if you want to build things from scratch. I'd suggest logos for lexing, LALRPOP / chumsky for parsing, and rust-gc for garbage collection.

The examples that come with chumsky and the chumsky tutorial and guide all define their parsers using closures.

chumsky's zero-copy rewrite has reached its first alpha release, and I have migrated my pep-508 parser to it, as suggested in my last announcement.

On my side, nom is still advancing well and a new major version is in preparation, with some interesting work a new GAT based design inspired from the awesome work on chumsky, that promises to bring great performance with complex error types. 2023 will be fun for parser libraries!

I am using chumsky because I like the API, but it doesn't support zero copy at the moment. Although efficiency is good to have, it is not my primary good. This will probably get supported once chumsky implements support for it (see upstream issue).
