Queryable References

[ratzdi]

A proposal for #1911. Introduced Reference as new response type in the method references. Extended ReferenceParams with array of reference kinds to filter by.

@ratzdi besides adding something to the spec we also require a client and server implementation to prove the usefulness. Is something like this available?

[ratzdi]

Hi @dbaeumer, not yet, but would it be enough if we implement the proposal on the server side in Clangd and on the client side in LSP4E/CDT LSP?

[dbaeumer]

Yes, we don't have requirements for clients / servers.

This being said I am not a fan of the long list of reference kinds. That one is hard to maintain across different languages. A tag model would be better IMO.

For the ReferenceKind thing, I think it needs to add other reference kinds:

• For field: field initialization. I think field initialization should be different to field write.
• Import
• Re-export
• For type: usage as type parameter
• For type: type alias

And there are many other language-specific things. For example in Java a type can be used in .class. In Rust there are immutable borrow usages and mutable borrow usages. I think not hardcoding all reference kinds in LSP is more extensible
