Send LSP error when GHC cannot be found

This will probably spam the message five times, as lsp-clients usually restart if a language server exits with a non-zero exitcode.

That's the clients problem. I tested it in vim and VSCode and it appears fine.

It will spam 5 times like @fendor says, but it's hard to improve until we merge the bindist wrapper into the hls wrapper and make the latter able to send a WindowShowMessageRequest ... which might take a while.

Is there a reason to do this for this error but not for the others?

We want to do it for the final error only. The script tries multiple methods to find a GHC version. Reporting all intermediate errors is gonna be excessive.

I see, so the other err_* functions are not in fact reporting errors.

Anyway, if you're into the idea, there's also window/logMessage.
