* feat(term): replace vterm with ghostel as the terminal engineCraig Jennings15 hours1-145/+0
| | | | | | | | I swapped the terminal engine from vterm to ghostel (libghostty-vt) everywhere. term-config replaces vterm-config (the F12 terminal, the C-; x menu, tmux history capture), and ai-term replaces ai-vterm (the F9 Claude-agent launcher). ghostel renders the agent TUI without vterm's flicker under heavy streaming, and one engine now covers every terminal workflow. 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.
* feat(vterm): unify the keys in vterm copy-mode and tmux historyCraig Jennings2026-05-111-3/+4
| | | | | | | | `vterm-copy-mode' and the `C-; x h' tmux-history buffer now share one key story. `M-w' copies the active region and stays put, so I can copy several things in a row. `C-g', `<escape>', or `q' leaves (resuming the live terminal, or closing the history buffer) without copying. `RET' is unbound (no special "copy and exit"). In copy-mode that meant removing vterm's default `RET' -> `vterm-copy-mode-done' binding. Before, `M-w' exited and copied as it went, which made grabbing more than one selection awkward. The history buffer's `cj/vterm-tmux-history-copy-and-quit' was the copy-and-exit one-shot. It's gone. `M-w' then `q' is the equivalent. I also moved `cj/vterm-tmux-history' from `C-; x C' to `C-; x h' (unshifted, and it frees `C') and refreshed the file's stale commentary header, which still referenced the old `C-; V' prefix and `<pause>'.
* fix(vterm): use a block cursor in vterm-copy-modeCraig Jennings2026-05-101-11/+11
| | | | | | The 3-pixel bar was visible but a block matches the rest of my Emacs cursor and lets the standard cursor color and `blink-cursor-mode' behavior carry through unchanged. Same enter/exit semantics: forced visible on entry, buffer-local override killed on exit so the live terminal goes back to the TUI's chosen state. Update the test expectations and rename the "prior-was-box" boundary test to "prior-was-hbar" so it still proves the override does something (the prior and the override would otherwise both be `box').
* test(vterm): cover the copy-mode exit chain end-to-endCraig Jennings2026-05-101-0/+93
| | | | | | | | | | | | | The unit tests for the cursor-restoration hook only exercised the helper in isolation. The real integration -- toggling the minor mode and watching the hook fire as part of the chain -- wasn't covered. If `vterm-copy-mode-done' or `cj/vterm-copy-mode-cancel' broke their exit semantics (or our hook stopped firing on `vterm-copy-mode-hook'), the unit tests would still pass but the cursor would stay stuck on the bar in real use. Add five integration tests that toggle the actual minor mode through stubbed `vterm--enter-copy-mode' / `vterm--exit-copy-mode' (so we don't need a live vterm process) and assert the cursor moves through the full lifecycle: nil -> bar on enter, bar -> killed-local on exit. Cover all three exit paths Craig hits in normal use: - vterm-copy-mode -1 directly (the toggle) - vterm-copy-mode-done with an active region (M-w / RET) - vterm-copy-mode-done with no region (line-selection branch) - cj/vterm-copy-mode-cancel (C-g / <escape>) Plus a multi-cycle test so a regression in `kill-local-variable' handling shows up.
* fix(vterm): force a visible cursor in vterm-copy-modeCraig Jennings2026-05-101-0/+51
vterm's C module sets `cursor-type' to nil whenever the underlying TUI sends DECTCEM (`\e[?25l') to hide the terminal cursor. Most full-screen TUIs do this on startup — Claude Code in an ai-vterm being a daily example. Once the cursor is hidden at the buffer level, vterm-copy-mode inherits that nil and the user can't see where point is when navigating to select text. Selection still works, but you're flying blind. Add a `vterm-copy-mode-hook' that forces `cursor-type' to a 3-pixel bar on entry and kills the buffer-local override on exit. The bar shape is drawn between characters rather than by inverting one, so heavy TUI face properties don't hide it either. On exit the live terminal goes back to whatever vterm's tracking says, so the TUI's chosen cursor state resumes. 4 ERT tests cover the hook's enter/exit behavior and confirm registration on `vterm-copy-mode-hook'.
