So I'm not sure if this is even possible with the language server protocol which is why I'm asking this here first instead of in a github issue, but I noticed that hover hints that show a function's signature don't use semantic highlighting. Is this possible to implement in RA or blocked upstream in the protocol?
I think that's not possible to implement sadly
Though, I haven't researched this recently, i won't be surprised if there's some proposal to that end already on the LSP repo
For some reason I didn't think of checking the LSP repo for this first but yes you were right, if I'm not mistaken this issue there is already asking for it. :thumbs_up:
There are a few issues about highlighting/formatting in hover and signature help for vscode but it doesn't look like it's going to happen any time soon.
