tao VS langs-in-rust

If you want some prior work on this, I've implemented effect-objects-as-return-values in my own language Tao, using uniqueness types. There's still work to be done, but I think it's sufficient as a proof of concept that this approach is viable without type soup.

I've personally found through my experiments working on my language Tao that having effects be a property of the return value and not the function itself is very useful and opens up a lot of doors, like iterators that generate effectful values and more precise control over when side effects occur and in what context.

If you’d like to see some examples of great error messages written by a language with a parser combinator, I recommend you check out tao, which is parsed via chumsky, and provides rust-like error messages with the help of ariadne! I have been fiddling with writing my own language for a while now, and after trying out the alternatives, I found Chumsky to be great to work with, and can not recommend it enough. There are also great examples that you can find in the repo as well!

Tao: A statically-typed functional language\ (0 comments)

I've been developing both throughout the development of Tao, my own hobby language. It's since developed quite an extensive syntax (see here for an example: https://github.com/zesterer/tao/blob/master/examples/99.tao), so you can count it as evidence that chumsky scales to complex grammars: https://github.com/zesterer/tao

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
