chumsky VS rustle

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).

Now that I've got your attention, check out our project on github: https://github.com/pintariching/rustle

I’m sure many would be interested in that! Especially the folks working on rustle. They’re venturing down a path very similar to the one you appear to have explored quite thoroughly already.

Rustle: Svelte compiler rewritten in Rust\ (51 comments)

Yes, most of the .rs files in https://github.com/pintariching/rustle/blob/main/src/compile... are empty. I was looking as I've been using the nom [0] parser combinator create to build an experimental compiler and I'm curious to see how other Rust compiler projects are doing parsing.
