From 9e069a310d14f9b6ebbe6e3747240e7844d9ffcb Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Sat, 20 Jun 2026 10:51:51 -0400 Subject: fix(windows): keep the pulled-away window on the arrow's edge The sole-window pull split toward the arrow at 50/50, so a fullscreen terminal jumped above the revealed buffer at half height. Now the reveal opens on the opposite side and is minimized to a sliver, so the current window keeps the arrow's edge near-full and the sticky windsize arrows shrink it step by step, matching the feel of resizing an existing split. --- modules/ui-navigation.el | 46 +++++++++++++++++++++++++++------------------- 1 file changed, 27 insertions(+), 19 deletions(-) (limited to 'modules/ui-navigation.el') diff --git a/modules/ui-navigation.el b/modules/ui-navigation.el index 00fa841e1..f53924ebb 100644 --- a/modules/ui-navigation.el +++ b/modules/ui-navigation.el @@ -75,26 +75,31 @@ resize -- each moves the active window's divider in the arrow's direction "" #'windsize-up "" #'windsize-down) -(defun cj/window-arrow-direction (key) - "Map a windsize arrow KEY description to a split direction. -KEY is one of \"\" \"\" \"\" \"\"; returns -left/right/above/below respectively, or nil for anything else." +(defun cj/window-pull-side (key) + "Map a `C-; b' arrow KEY to the side the revealed window opens on. +The arrow names the edge the current window shrinks toward, so the new +window opens on the *opposite* side and the current window keeps the +arrow's edge: -> above, -> below, -> right, + -> left.
