Doesn't show method descriptions, param types, or anything else in coc.nvim

[rosshadden]

I don't really know where to ask this, because I'm not sure if it's a problem with my coc language server config or if it's a problem with nimlsp. I use the same config that everybody and their mother recommends:

		"nim": {
			"command": "nimlsp",
			"filetypes": [ "nim" ],
			"trace.server": "verbose"
		},

This works and has worked for quite a while now. However it only shows basic completions. They don't seem to always be context-aware and don't show anything more than just the names themselves.

Here's an example from nim in my neovim with the above language server config:

Every other language I use with an LSP configured shows much more. Here's an example from a Go project within reach:

Am I doing something wrong? Is something broken on my end? Or are these LSP features not implemented in nimlsp at this time? Thanks!

I think it's an extra LSP thing that is not currently implemented, possibly textDocument/signatureHelp but LSP is unfortunately quite poorly documented for what each thing is supposed to do..

I wonder why this works with the VSCode extension but non on Coc

I can confirm that it works on VSCodium as well, but not on CoC...

Apparently it shows multiple identical suggestions and a random few of those have the help text on them:

While others don't:

I recently implemented combining stuff with the same name into one entry. But for the full completion I think we need textDocument/signatureHelp implemented. I'll look into it
