Hi,

I would like to try my hand at this issue. Would that be ok?
@jonmeow I saw that you have recently cleaned up the language server.
Do you already have a plan on how to proceed with this?

Thanks and best regards

At present I'm planning on:

1. Adding test infrastructure for the language server.
2. Rewrite current handlers, particularly to do better parsed/checked document caching.
3. Adding a few new handlers, like hover, to get a little more demonstration of functionality.

Looking at this issue, the missing items it notes (goto, renaming, auto complete) seem like they're contextual to the mentioned GSoC 2023 work; IIRC maybe more work had been planned? Where things are now, the short-term goal is just a few more features and the long-term goal is a full LSP implementation. I may end up closing this issue once the LSP implementation is a little further along, since we're not using it for tracking.

If you'd like to work on the language server, it may be better to wait until after the current handler rewrite is done. I think tests are really important, and I'll probably be reworking the current code to better fit caching structure. If you're inclined to pick things up, it might be helpful to check in on Discord -- #editor-integrations has been quiet, but seems a good spot to try and coordinate.

@jonmeow Ok, that sounds good. I'll head over to discord for further discussion.
