Add powerline segment(s)

Check #97, I have a API pending.

[neersighted]

Said API is ale#statusline#Count(buffer), which returns a pair [E, W] if there is data or 0 if there is no data.

That is, a 0 as in the plugin has not run and cannot determine if there are any errors, not 0 errors.

@neersighted great, I will be watching that PR.
It would be great if there was another function that returns the type and message of the current warning/error if the cursor is on the same line (for replacing the echo right now).

[neersighted]

Sure, just factor out what you need from EchoCursorWarning into its own function, and make EchoCursorWarning call that. 😀

@neersighted so i understand that as per #97 #Count() will always return a tuple with [0, 0] in the default state? (i don't need the information about startup, just to make sure I use it correctly)

[w0rp]

Yep, as of right now you get [0, 0] when before linters have been run, and again [0, 0] if linters have been run and no problems have been found.

I think with the merge of #97 and an example of how to use it included in airline this is safe to close.
