Refresh `gina-status` buffer whenever you enter it

[resolritter]

Hello!

I don't have exact reproduction steps, but sometimes, when I re-enter the gina-status buffer, it's not updated after a commit. That may also happen if you commit something outside of Vim and come back to it later.

In those situations, I'm often forced to call :edit which refreshes the buffer through autocommands. It would be very nice if the buffer automatically refreshed whenever you switched to it. I am thinking of something along those lines:

fun! s:RefreshIfPreviouslyInvisible()
  if win_findbuf(bufnr('#')) == []
    " refresh here
  endif
endfun

autocmd BufEnter <buffer> call s:RefreshIfPreviouslyInvisible()

as win_findbuf only checks if a buffer is open in the current tab, this "automatic refresh" wouldn't happen if gina-status is already open in a split (this concern is necessary to avoid refreshing the buffer while the cursor is already doing something in it).

Well, so what this issue for? Bug report or feature request or else?

The issue suggests that this behavior "Refresh gina-status buffer whenever you enter it" is not happening currently, but is desirable. It'd be a feature request if this is not intended by design or a bug report if you believe this is supposed to be happening already.

The behavior I notice currently is:

• Exit a gina-commit buffer
• Create a new gina-status buffer => it is updated when I create it

However, if I switch back to a existing status buffer, it seems like it doesn't update on BufEnter. It should, because changes could have been made on a terminal (ex: Gina!! add -i) or outside of vim.

The workaround for this problem is to manually call :edit, which will trigger the autocommand to refresh the buffer, but I find this is annoying to keep doing manually for every single commit.

When I opened this issue, I did not know what to do. Just recently I took a deeper look at the autocommands and made a script which works decently well.

fun! RefreshStatus()
  if win_findbuf(bufnr('#')) == []
    set modifiable
    call deletebufline(bufnr('%'), 1, line('$'))
    set nomodifiable
    call gina#util#doautocmd('BufReadCmd')
  endif
endfun

autocmd BufEnter,FocusGained <buffer> call RefreshStatus()

I think this solution is fine. Thanks for your time.
