[cfe-dev] Will clangd support per parameter completion information?

[Ilya Biryukov via cfe-dev]

Hi Francisco,

The LSP has this feature, it's called signature help:
https://github.com/Microsoft/language-server-protocol/blob/master/protocol.md#textDocument_signatureHelp
.

We don't have it in clangd, but it's not hard to implement it.
Actually, discussion about it came up during one of recent changes that
improve completion: https://reviews.llvm.org/D37101.
+raoulwols, who is the author of the change. Raoul, maybe you had plans
regarding signature help?
