Show HN: Create a full language server in Go with 3.17 spec support (github.com)

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 ..)

Very nice. Now I want to build a language server. If only I had anything to build it for.

Have you tried out https://github.com/tliron/glsp?

I really like the interface-based auto-registration pattern, so elegeant!

The implementation of HoverHandler seems clever... no manual wiring. That's the kind of API design that makes Go's implicit interfaces shine.

I'm curious: How does error recovery work when a handler panics? Does the server keep the connection alive, or does it tear down?

Just to show what it can do, some language servers built with it
