feat(view): global status line option

[matoous]

Add option to render single global status line instead of rendering status line per view.

With

[editor.statusline]
render = "per_view"

(default)

with

[editor.statusline]
render = "single"

Fixes: #2254

@CBenoit could you adjust the label to “waiting-on-review” pleas?

I am not really familiar enough with the rendering code to have a confident judgment on this PR, but from what I can tell, this change looks good to me. It's surprisingly small.

From what I can tell, is it basically just hiding the individual status lines, or does it actually prevent them from rendering in the first place?

Great work @matoous , I love using a single status line!

Don't we also need something equivalent to neovim's winbar to show the file name in at all times? If you have multiple buffers next to each other, you don't know which file is which otherwise when using single status line.

Here's an screenshot of what I mean, latest neovim with laststatus=3 (global status line) and winbar=%f (showing file path):

I just feel these 2 features belong together. But maybe this should be in a separate PR? Let me know your thoughts!

@dahmc I am sorry, I am not sure if I understand. The filename of the document in currently active window is displayed in the status line. Furthermore, there's bufferline for buffers. I am not sure how else we could display the filename withing single status line.

@matoous The filename for the currently active buffer is shown in the status line, correct.

What I'm referring to is that we now don't know what the filename of the other buffer is, until we switch to it.

The bufferline doesn't really help here, because there could be 10 open buffers, and it's now clear what the filename of the inactive buffer is exactly.

Does that make sense? :)

[matoous]

@dahmc understood. Yet, I am not sure how that would be solved if we have single status line. Maybe a configuration option for bufferline would do? If you want to see the filename for all open views then I don’t think singular status line would work.

[cd-a]

@matoous Yeah I think the only way to make this work would be how it's done in neovim what I've shown in my screenshot above, using something like a winbar, which sits below the buffer line

[TornaxO7]

may I ask if I can try to take over this since this PR is almost one year old now?

[matoous]

@TornaxO7 sure, feel free to.

[TornaxO7]

Ok, so would it e fine, if I only focus on the statusline?

[matoous]

Closing in favor of @TornaxO7 's PR.
