🔖 Feature description

Currently it seems impossible to set settings for lsps over nix. Worse even I think the only option for setting lsp settings is to disable the lsp in nix and then use lua to start it, but I might be wrong, my lua knowledge isn't particularly good

✔️ Solution

An option like vim.languages.<name>.lsp.settings or maybe even, if the language has multiple lsp clients something like vim.languages.<name>.lsp.<lsp-name>.settings. I might also be nice to expose other lspconfig things, like on_attach.

This has been on my radar for a long while. I'd really like to redo the logic for language servers, but couldn't find the time to sit down and go over all language modules.

In theory it's not a very large change, currently LSP options are not exposed because they are inherited from variables in a let in block for each language. It should be somewhat trivial to move those into module options that can get merged. I'll try to take a look at this after Tuesday, but feel free to take a look at this if you'd like. If I do end up forgetting, also do feel free to remind me.

I've started working on this in #643. The API is reasonably simple, so converting most of the languages will be easy. Unfortunately I'm out of time for today, but I'll be going over it over this week.
