feat(term): replace vterm with ghostel as the terminal engine

2026-06-05T10:28:58+00:00

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): forward to the pty in vterm-mode

2026-05-18T21:00:08+00:00

`' is bound globally to `keyboard-escape-quit' in modules/keybindings.el, so Emacs swallows the key before it can reach the pty. Bind it in vterm-mode-map to cj/vterm-send-escape, which writes a literal ESC byte via vterm-send-string. tmux's copy-mode `cancel' binding then fires; vi-mode exits, fzf cancel, etc., also work as expected.

feat(vterm): forward wheel events and route C-; x c into tmux copy-mode

2026-05-18T20:49:29+00:00

vterm-mode-map binds only mouse-1 and mouse-yank-primary, so wheel events fall through to Emacs scrolling and never reach the pty. tmux's `set -g mouse on' never sees them. Bind wheel-up / wheel-down (and X11 mouse-4 / mouse-5) to send SGR mouse-wheel escapes via vterm-send-string. tmux's existing WheelUpPane / WheelDownPane bindings route into copy-mode from there. For keyboard parity, route C-; x c through cj/vterm-copy-mode-dwim, which sends C-b [ when a tmux client is attached and falls back to vterm-copy-mode otherwise. tmux's history-limit is now reachable from either entry point. The matching copy-mode keys (M-w stays, C-g / q / Escape exit, Enter unbound) land in the dotfiles repo alongside.

feat(vterm): show tmux scrollback history in place

2026-05-13T20:39:40+00:00

`cj/vterm-tmux-history' previously used `pop-to-buffer', which routed the history view through display-buffer-alist -- in an agent window that often meant a split or a hand-off to another window, costing the agent its frame slot. `switch-to-buffer' instead drops the history into the selected window directly; the existing quit handler already restores the origin in that same window via `set-window-buffer'. New test asserts the in-place behavior: starting single-window with a vterm origin, invoking the command leaves `(one-window-p)` t with the history buffer in the original slot. The existing render test no longer needs its `pop-to-buffer' stub since `switch-to-buffer' works in batch.

feat(vterm): unify the keys in vterm copy-mode and tmux history

2026-05-11T15:02:17+00:00

`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', `', 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 `'.

refactor(ai-vterm): rename Claude-specific names to a generic "agent"

2026-05-11T12:18:20+00:00

I may add other terminal agents to this launcher (aider, an open-source LLM TUI), so the buffer prefix, the user knob, and the internal helpers shouldn't say "Claude". The module name (ai-vterm) and the `cj/ai-vterm-*` customs were already generic. This finishes the job: - buffer prefix `claude []` -> `agent []` (the `defconst` and the matching display-buffer-alist regex move together) - `cj/ai-vterm-claude-command` -> `cj/ai-vterm-agent-command` (the default still runs the `claude` CLI, with a docstring note on swapping it) - `cj/--ai-vterm-claude-buffers` / `-displayed-claude-window` / `-reuse-existing-claude` -> `-agent-*`, and their test files renamed to match - prose in the module commentary and docstrings, plus the matching test docstrings and buffer-name literals `vterm-config.el` hardcodes the same buffer prefix in `cj/--vterm-toggle-buffer-p` (F12 excludes agent buffers from its candidate set), so that literal moved too. Collapsing it into the shared `cj/--ai-vterm-name-prefix` is a cleanup for another day. After a reload, a project's buffer opens as `agent [foo]` instead of `claude [foo]`. Old buffers keep their names until killed. I also corrected two stale `eshell-vterm-config.el` references in ai-vterm.el docstrings (that module was split into `vterm-config.el`). Two things keep saying "Claude": the `cj/ai-vterm-agent-command` default value (the actual CLI), and the "Claude Code" example in `vterm-config.el`'s cursor-restore docstring (a concrete TUI example, not branding). 90 tests pass. `make validate-modules` clean.

test(vterm): cover AI-vterm inheritance of the vterm copy path

2026-05-11T10:17:44+00:00

I added three ERT cases around `cj/vterm--current-tmux-pane-id` and `cj/vterm-copy-mode-cancel`: the pane-id lookup rejects a non-`vterm-mode` buffer, it still resolves a `claude [...]`-named buffer by process TTY, and the copy-mode cancel command errors outside copy mode. The pane-id-by-TTY case pins the contract that AI-vterm buffers get the copy commands because they're `vterm-mode` buffers, not because of any buffer-name check.

refactor(vterm): move vterm prefix to C-; x and add prompt nav

2026-05-10T17:39:44+00:00

The personal vterm map was on `C-; V'. The capital V costs a Shift on every keystroke into the menu, which adds up for the daily `C-; V c' / `C-; V C' bindings. Move the prefix to lowercase `C-; x' -- free, no Shift, faintly mnemonic (xterm/execute). The lowercase `C-; v' stays the version-control menu. Wire `vterm-next-prompt' and `vterm-previous-prompt' into the menu so they're reachable everywhere, not only inside vterm-copy-mode-map. Lowercase `n' and `p' match Emacs's idiom for next/previous; bump "new vterm" up to capital `N' for the rare new-buffer case. Drop the `' binding for `vterm-copy-mode' from `vterm-mode-map'. Modern keyboards rarely have a Pause key and `C-; x c' is the canonical entry now. Update which-key labels and tests; `test-vterm-keymap-includes-history-and-copy-bindings' now asserts the new prefix, and two new tests cover prompt-nav bindings and the dropped `' binding.

refactor: split eshell-vterm-config into eshell-config and vterm-config

2026-05-10T08:25:35+00:00

The combined module had grown to 573 lines covering two unrelated subsystems with no shared state — the eshell shell-mode commands and the vterm/F12 toggle. The header even rendered this with two `;; ----` dividers. Split into two focused modules. eshell-config.el keeps the eshell user commands and package wiring (~170 lines). vterm-config.el keeps the vterm package, the tmux history capture command, the F12 toggle, and the C-; V keymap (~400 lines). Update init.el to require both, point the four vterm test files at vterm-config, and refresh the cross-module commentary in cj-window-geometry.el and cj-window-toggle.el. No behavior change. Full test suite green; validate-modules clean.

Add Emacs-native vterm copy workflows

2026-05-10T07:44:21+00:00

Add an Emacs-first copy workflow for vterm and tmux. C-; V c enters vterm copy mode, C-; V C captures tmux pane scrollback into a temporary Emacs buffer, M-w copies and returns, and C-g/Escape cancel without copying. This also adds clickable URLs, removes the bad vtermf binding, unbinds C-c C-t, and tests the vterm/tmux keymap behavior.
