patch 9.1.0407: Stuck with long line and half-page scrolling Commit: https://github.com/vim/vim/commit/58448e09be497a8abb595ae309b6edfbc8e0e05a Author: Luuk van Baal <luukvb...@gmail.com> Date: Sat May 11 11:27:52 2024 +0200
patch 9.1.0407: Stuck with long line and half-page scrolling Problem: No scrolling happens with half-page scrolling with line filling entire window when 'smoothscroll' is disabled. (Mathias Rav, after v9.1.0285) Solution: Adjust amount to move cursor by so that it is moved the same number of lines as was scrolled, even when scrolling different number of lines than requested with 'nosmoothscroll'. fixes: #14743 closes: #14746 Signed-off-by: Luuk van Baal <luukvb...@gmail.com> Signed-off-by: Christian Brabandt <c...@256bit.org> diff --git a/src/move.c b/src/move.c index 797184812..3e589caae 100644 --- a/src/move.c +++ b/src/move.c @@ -3158,9 +3158,10 @@ static int get_scroll_overlap(int dir) /* * Scroll "count" lines with 'smoothscroll' in direction "dir".
