My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=main 2026-06-05T10:28:58+00:00 2026-06-05T10:28:58+00:00 Craig Jennings c@cjennings.net 2026-06-05T10:28:58+00:00 urn:sha1:ebdf9e466b0e1f86e9b7d76650ac32408273e7a7 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. 2026-05-16T07:56:25+00:00 Craig Jennings c@cjennings.net 2026-05-16T07:56:25+00:00 urn:sha1:d618bb4620d5d651027e772b8ccc490e1bab6d80 - popper-config.el: move `(popper-mode +1)` and `(popper-echo-mode +1)` from the use-package `:init` block into `:config`. `:disabled t' on use-package skips `:config' but still runs `:init', so the previous shape enabled popper-mode on every load, including batch / test runs, despite the disabled marker. - modeline-config.el: make `cj/modeline-vc-fetch' fall back when the internal `vc-git--symbolic-ref' is missing. `require' uses `nil 'noerror', the call sits inside an `fboundp' guard, and `ignore-errors' wraps the call itself so an Emacs version that renames or removes the accessor leaves `branch' at `vc-working-revision''s output instead of crashing the modeline. - ui-config.el: guard the cursor-color `post-command-hook' behind `(display-graphic-p)' both at install time and inside the function body. Batch / TTY runs short-circuit cleanly with no per-command overhead. A `server-after-make-frame-hook' catches the daemon case where the first GUI frame is created after ui-config loads and installs the hook lazily. Updates test-ui-config--buffer-cursor-state and test-ui-cursor-color-integration to stub `display-graphic-p' so the work body still runs under batch. - nerd-icons-config.el: drop `:demand t' (`:defer t' now), keeping the `:config' advice install as the natural lazy-on-load path. Add a `with-eval-after-load 'nerd-icons' block as a safety net for the already-loaded case on re-eval; the block uses `advice-member-p' so the advice never stacks. 2026-05-11T14:12:32+00:00 Craig Jennings c@cjennings.net 2026-05-11T14:12:32+00:00 urn:sha1:a70bb985c86aee2b701b40d5c3fae720863cfa4e `vterm-mode' sets `buffer-read-only', so `cj/set-cursor-color-according-to-mode' painted the cursor with the read-only color (orange) whenever point was in a vterm. That includes the live terminal, not just `vterm-copy-mode'. But a live terminal takes input: keystrokes go to the process, not the buffer. So a live vterm now reports `unmodified' instead. `vterm-copy-mode' still reports `read-only': there it really is a read-only Emacs buffer the user navigates, and the orange cursor is the right signal. I pulled the state cond out of `cj/set-cursor-color-according-to-mode' into `cj/--buffer-cursor-state' so it's unit-testable without a real frame or `set-cursor-color'.
