I'd like to share a naive language server I wrote for Roc some time ago: https://github.com/ayazhafiz/roc/releases/tag/langsrv. I do not intend it to be more featureful than what it already supports, as the main focus for Roc's editor support is the Roc editor. However, since that is still WIP, I hope this may be useful to anyone getting started with Roc who's looking for some help in their current editor along the way!
Unfortunately, I only have access to a 12.6 aarch64 macOS machine, so that is the only prebuilt binary I can provide.I've left more instructions on building and using the language server in the release above, if you are interested in using this.
It was brought to my attention that the server isn't up to date with the builtins on the latest Roc nightlies. I've updated the release to the latest version of Roc, and the arm64 macOS binary provided there.
