Two behavior changes fall out of the swap. F9 launches in a terminal frame now: ghostel renders in TTY frames, so the old GUI-only guard is gone. Terminal windows no longer dim when unfocused: ghostel resolves its palette into the native module per-terminal, so there's no per-window color hook to dim through the way vterm had. auto-dim drops its vterm color-advice path, the dashboard Terminal button launches ghostel, and the vterm and vterm-toggle packages are removed. The tmux pane-history and copy-mode machinery carried over unchanged. It keys on the pty tty, which ghostel exposes. 2026-05-27T19:36:57+00:00 Craig Jennings c@cjennings.net 2026-05-27T19:36:57+00:00 urn:sha1:84d8ab6a3ad97697a717a770c42010e9ec9076e5 The F10 music playlist opened at a fixed fraction every time, so any manual resize was lost the moment it was toggled closed. Now the toggle captures the window's size on close and reopens at that height, for the rest of the session. The mechanism is generic, not music-specific. cj/window-size-fraction (geometry-lib) is the pure kernel: a clamped window/frame ratio. cj/side-window-capture-size and cj/side-window-display (toggle-lib) wrap it for any display-buffer-in-side-window consumer — height for top/bottom, width for left/right — storing the remembered fraction in a caller-supplied state var. It mirrors the direction-split toggle pattern the vterm dispatchers already use, but for atomic side windows that can't be split. music-config wires F10 to it: cj/music-playlist-window-height is the default, cj/--music-playlist-height holds the remembered value (in-memory, resets each session). 12 new tests across the two libs, Normal/Boundary/Error each covered. 2026-05-25T09:10:38+00:00 Craig Jennings c@cjennings.net 2026-05-25T09:10:38+00:00 urn:sha1:3f75b39bbbc4e1c136d3f786024c5c1ed19011ce F9 split a third window into a frame that was already divided in two, wedging the agent into the middle or a skinny extra column instead of taking the half it should occupy. The display rule only knew how to reuse a window already showing an agent or to split a fresh one. With a plain two-pane layout it fell through to the split and added a window. I added a display action, cj/--ai-vterm-reuse-edge-window, that reuses the window already forming the target half (the right column on a desktop, the bottom row on a laptop), found by a new cj/window-at-edge helper. It records the displaced buffer with display-buffer-record-window, so toggling off restores that buffer through the native quit-restore-window. The slot's buffer swaps between the agent and whatever it displaced, and no window is created or deleted. The split path still handles a single-window frame or a layout split on the other axis, and the lone fullscreen agent keeps its bury-and-restore-in-place behavior. 2026-05-10T20:31:27+00:00 Craig Jennings c@cjennings.net 2026-05-10T20:31:27+00:00 urn:sha1:8c12629f8c4c8726b7b74ad3912abd9cd1cade9c Same naming-convention fix as the other library renames in this series. Rename modules/cj-window-geometry.el -> modules/cj-window-geometry-lib.el and tests/test-cj-window-geometry.el -> tests/test-cj-window-geometry-lib.el. Update provide forms, file headers, and the (require 'cj-window-geometry) call sites in cj-window-toggle-lib.el, ai-vterm.el, vterm-config.el, and the test file. No behavior change.
