Started in case I ever build a language server, thanks! The interface looks very understandable, and the debug server looks really nice.
Now that I think about it, it might be really cool to add LSP to my CLI framework[0] (I already have tab completion for shells, why not make an editor plugin if it's this easy ..)
I wrote this for the infracost LSP so I could write multiple IDE extensions. Its not even really a language server, its just a neat way to parse the Terraform/Cloudformation and return diagnostics.
Language servers are cool!
