#1628 Feature/1628 Pop out documentation

[marcindawidziuk]

Hi, let me first say that this plugin is awesome.
The one big thing that was missing for me as an Elixir noobie is documentation.
This PR adds a very basic IEx based Documentation Provider, that so far have worked okay-ish in my Phoenix based project. Is that approach even a correct way to fetch docs?

Any and all feedback would be appriciated.

Is that approach even a correct way to fetch docs?

This is one way to do it. You could also do something like how the debugger works where it uses JInterface to talk to a running BEAM process. Finally, you could read the docs out of the .beam files are render them all in Kotlin/Java. That was the way I would have done it, but this is a good start for now. Having something to iterate on is better than having no docs. ❤️

Works for fully-qualified module function and arity even in pipelines

Doesn't take into account aliasing

I'll look into if I can fix that before merging.

[KronicDeth]

It not working with aliased modules is a bug in resolveModuleName since I said it should work with aliases. Find usage works with calls on aliases, so I must have a method that works for that, probably using references directly and not using resolvedModuleName, so it is just resolvedModuleName that is bugged.

[KronicDeth]

Resolving the resolvedModuleName will be a larger change that I don't want to mix with your changes, so I'll add it later.
