patch 9.1.0175: wrong window positions with 'winfix{width,height}' Commit: https://github.com/vim/vim/commit/5866bc3a0f54115d5982fdc09bdbe4c45069265a Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Wed Mar 13 20:17:24 2024 +0100 patch 9.1.0175: wrong window positions with 'winfix{width,height}' Problem: winframe functions incorrectly recompute window positions if the altframe wasn't adjacent to the closed frame, which is possible if adjacent windows had 'winfix{width,height}' set. Solution: recompute for windows within the parent of the altframe and closed frame. Skip this (as before) if the altframe was top/left, but only if adjacent to the closed frame, as positions won't change in that case. Also correct the return value documentation for win_screenpos. (Sean Dewar) The issue revealed itself after removing the win_comp_pos call below winframe_restore in win_splitmove. Similarly, wrong positions could result from windows closed in other tabpages, as win_free_mem uses winframe_remove (at least until it is entered later, where enter_tabpage calls win_comp_pos). NOTE: As win_comp_pos handles only curtab, it's possible via other means for positions in non-current tabpages to be wrong (e.g: after changing 'laststatus', 'showtabline', etc.). Given enter_tabpage recomputes it, maybe it's intentional as an optimization? Should probably be documented in win_screenpos then, but I won't address that here. closes: #14191 Signed-off-by: Sean Dewar <6256228+seandewar@users.noreply.github.com> Signed-off-by: Christian Brabandt <cb@256bit.org>

.SH SYNOPSIS
.br
.B vimdiff

.PP
.B gvimdiff
.SH DESCRIPTION
.B Vimdiff
starts
.B Vim
on two up to eight files.
Each file gets its own window.
The differences between the files are highlighted.
This is a nice way to inspect changes and to move changes from one version
to another version of the same file.
.PP
See vim(1) for details about Vim itself.
.PP
When started as
.B gvimdiff
the GUI will be started, if available.
.PP
In each window the 'diff' option will be set, which causes the differences
to be highlighted.
.br
The 'wrap' and 'scrollbind' options are set to make the text look good.
.br
The 'foldmethod' option is set to "diff", which puts ranges of lines without
changes in a fold.  'foldcolumn' is set to two to make it easy to spot the
folds and open or close them.
.SH OPTIONS
Vertical splits are used to align the lines, as if the "\-O" argument was used.
To use horizontal splits instead, use the "\-o" argument.
.PP
For all other arguments see vim(1).
