There's a tab local variable t:zoomed that indicates whether it is currently zoomed (value 1) or not (value 0).

EDIT: Ideally you can show this in the status line, what would you expect such an API to do ?

Yes display it in the statusline.
I believe t:zoomed is not loaded until zoom operation/toggle is invoked. So it will be an undefined variable to start with.

No different from tmux pane zoom and the tmux's zoom status flag. Thanks.

Thanks.

I have added a new API zoom#statusline(), you can add it to your statusline with something like this :

set statusline+=%{zoom#statusline()}

It spits out the string 'zoomed' if we're zoomed currently and blank if not.

Yes, I pulled this in immediately - thanks again.

BTW, probably an edge case.
Open vim, single window (no splits), hit C-w m.
Vim will rightfully say "Already only one window".
zoom#statusline() should probably not say zoomed in this case i.e s:is_zoomed() probably shouldn't think we're zoomed() if there's only one window.

That would be a question for vim-zoom, whether we should invoke zoom or skip it in case there is just 1 window / split. The statusline is only displaying the zoom status so that's doing it's job correctly.

Indeed - question for vim-zoom.

I think it's a fair point that we should just not do anything in case we're already the only split in the current tab and vim-zoom is invoked, i'll make the changes appropriately.

Thank you.

Great plugin 👍

When I add this to my .vimrc:
set statusline+=${zoom#statusline()}

I get a statusline that literally says "${zoom#statusline()}". I know this is an issue on my side but I'm wondering if anyone here might point me in the right direction.

@NeilsC sry there's a typo in the README, i'll fix it, it should be :
set statusline+=%{zoom#statusline()}

@dhruvasagar That did the trick, thanks!

Hi, is there a way to add it to vim-airline ?

@ovidius72 You'll need to refer to vim-airline help for that, :h airline-advanced-customizations specifically may be what you need to use.

@ovidius72 ,

function! AirlineInit()
    let g:airline_section_z = airline#section#create('%#__accent_bold#%{zoom#statusline()}%3l%#__restore__#/%L :%3v')
endfunction
autocmd User AirlineAfterInit call AirlineInit()
