I'd like to try Roc at some point and was wondering if rewriting my elm test runner (https://github.com/mpizenberg/elm-test-rs) in Roc could be a good project. Currently it's written in Rust and consists mainly of 2 things, (1) a CLI app (http, reading/writing files, calling other programs like the elm compiler, Node, redirecting outputs, etc.) and (2) a dependency solver (https://github.com/pubgrub-rs/pubgrub) which is mainly pure computation delegating side effects to the caller. I wouldn't start now since I have to finish few things in pubgrub first, but could probably start before the end of year.
Folkert de Vries (Sep 22 2022 at 08:31):the CLI platform is currently being worked on, so I think its progress and your availability will line up nicely. Also it would be really cool to have such a solver in roc. It would be interesting too see how it performs (and if in-place mutation has any value here)
Matthieu Pizenberg (Sep 22 2022 at 08:38):mutations play a big part in the algorithm performance I believe, but that would need to be benchmarked.
Matthieu Pizenberg (Sep 22 2022 at 08:45):I also have a benchmark setup to time the duration for solving all of elm packages. So this could easily serve as a benchmark comparing the rust and roc versions
