[Feature request] Add signature help

[InExtremaRes]

Is there a possibility of adding a signature help, so when you are calling a function (constructor, whatever) have a tooltip showing parameters name and type? It is very useful when calling a function with lots of arguments.

atom-ide-ui has this feature so, for instance, ide-typescript can use it directly. I don't know how much this package can (wants) use atom-ide-ui services or if is there any reason to do so.

Should be possible I think?
There's a signatureHelp command in tsserver, and atom-ide-ui SignatureProvider interface seems reasonable

[InExtremaRes]

Is any plans to integrate more (in whichever sense of the word) this package with atom-ide-ui?

[lierdakil]

There are no plans, but I don't see why not use a readily-available solution instead of inventing our own.

[InExtremaRes]

Yes of course, just out of curiosity... and well, atom-ide-ui has a lots of services already there.

The only trade off I can think is the very different looks of those tooltips. Maybe more info could be ported as well (quickinfo, etc), but you know, it is just a bagatelle.

Maybe more info could be ported as well

I don't mind, although not everybody likes atom-ide-ui, so probably a good idea to leave an "escape hatch" in, so to speak.

Seems this is either a dupe of, or related to #608
