feat: add nvim-tree awareness to avoid space collisions

[hlmtre]

Have just moved off fidget.nvim's legacy tag and am very excited! I have discovered a small bug - fidget draws over the nvim-tree window. See below screenshot.

It appears to do this whether or not nvim-tree is open before or after fidget's first appearance in that session of nvim.

Ugh, that’s because Fidget now uses editor-relative positioning and doesn’t know that it’s fighting for real estate with nvim-tree.

I’ll have to think about how to fix this. The pragmatic way is to teach Fidget to be aware of nvim-tree, but I’m wondering if there’s any generic way to avoid buffer collisions without having to teach Fidget about every tray-style plugin out there.

[hlmtre]

Perhaps a reasonable partial/temporary solution would be to give fidget an option to be offset from the right, specified in its configuration.

[j-hui]

Yeah, that would be the way to do it.

I was reading up on the nvim-tree API and it’s definitely doable for that one plugin at least.

(Note to self: other plugins: trouble.nvim, treesitter playground, aerial (?), telescope… ugh there’s so many.)

Is there a reason why the window-relative options are not currently exposed?

[j-hui]

@fitrh because I didn't get around to testing it yet...

Anyway, I just pushed a commit that adds this feature

[hlmtre]

Brilliant!

Thanks @j-hui. I looked through the commit and didn't realize neovim offered an API that would make for such a simple fix. Nicely done!

[j-hui]

No problem, glad it works for you (:

It was actually a feature in the legacy implementation that I actually wasn't sure if I wanted to bring back, because the idea of the notification window bouncing around from window to window was a little weird. (In fact, I think it used to be the default.) But I forgot about this use case for it, as a workaround to things like nvim-tree.

[j-hui]

Also, update: I added 22b2ed8 to expose an API for dynamically adjusting the horizontal offset, but still need to figure out how to integrate that with nvim-tree (I'm not sure how to query the window size).

I'm going to remove the bug label from this issue since a workaround exists, but I'll keep it open until Fidget properly integrates with nvim-tree (or until we decide to give up on that).
