patch 9.1.0170: Re-allow curwin == prevwin, but document it instead Commit: https://github.com/vim/vim/commit/d64801e913314d2e19dbb38f60e6d285238debff Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Tue Mar 12 20:46:12 2024 +0100 patch 9.1.0170: Re-allow curwin == prevwin, but document it instead Problem: more places exist where curwin == prevwin, and it may even be expected in some cases. Solution: revert v9.1.0001, but document that it's possible instead. (Sean Dewar) I've had a change of heart for the following reasons: - A quick 'n dirty [GitHub code search](https://github.com/search?q=%2F%28winnr%5C%28%5C%29%5Cs*%3D%3D%5Cs*winnr%5C%28%5B%27%22%5D%23%5B%27%22%5D%5C%29%7Cwinnr%5C%28%5B%27%22%5D%23%5B%27%22%5D%5C%29%5Cs*%3D%3D%5Cs*winnr%5C%28%5C%29%29%2F&type=code) reveals some cases where it's expected in the wild. Particularly, it made me aware `winnr() == winnr('#')` is possible when curwin is changed temporarily during the evaluation of a &statusline expression item (`%{...}`), and is used to show something different on the statusline belonging to the previous window; that behaviour wasn't changed in v9.1.0001, but it means curwin == prevwin makes sense in some cases. - The definition and call sites of back_to_prevwin imply some expectation that prevwin == wp (== curwin) is possible, as it's used to skip entering the prevwin in that case. - Prior to v9.1.0001, `:wincmd p` would not beep in the case that was patched in v9.1.0001, but now does. That resulted in #14047 being opened, as it affected the CtrlP plugin. I find it odd that `:wincmd p` had cases where it wouldn't beep despite doing nothing, but it may be preferable to keep things that way (or instead also beep if curwin == prevwin, if that's preferred). - After more digging, I found cases in win_free_mem, enter_tabpage, aucmd_restbuf and qf_open_new_cwindow where curwin == prevwin is possible (many of them from autocommands). Others probably exist too, especially in places where curwin is changed temporarily. fixes: #14047 closes: #14186 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
