How do you do anything at all?

Hi,

I have a hard time finding absolutely any documentation that explains how to create a language server extension. I'm aware of the quirky little "tutorial" explaining what language servers are. But it does not, whatsoever, help me get started on implementing my own; the methods to use are not thoroughly explained, the repo architecture is not explained, I don't know what files, dependencies, and extensions are necessary, I do not know where and how to register allowed syntax and what diagnostics to report. The list is genuinely endless.

So, how do you create a language server extension? At all?
I'm getting a bit frustrated with trying to figure things out. None of the samples or other implementations make sense to me and look absolutely bonkers over-complicated.

I want to create a language server along with a preview window for GitHub issue templates. I can't imagine it can possibly be more complicated than validating the user's file against some YAML schema.

You can refer to samples:

Thanks for the reply.

The lsp-sample you linked has little to no explanations. Where do I provide the allowed grammar, the tokens, the suggestions, the diagnostics? How do I actually analyze the user's input? Provide snippets? Reference previous tokens across the file?

Please provide more information if you can.
