My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=main 2026-05-16T07:56:25+00:00 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. 2025-11-14T08:25:19+00:00 Craig Jennings c@cjennings.net 2025-11-14T08:25:19+00:00 urn:sha1:dbba172fdb815fd67bbf7a6baf73a53d580c9fed The cursor color was not updating correctly when switching buffers or modifying files. The original implementation used window-buffer-change and other specific hooks, but these were insufficient and internal buffers were interfering with cursor color updates. Root cause: - Cursor color is global (one cursor for all of Emacs) - Previous hooks fired in internal buffer contexts (*Echo Area*, *temp*) - This caused cursor to be set to white (unmodified) even when in read-only buffers like dashboard Solution: - Use post-command-hook which runs after every command in current buffer - Ignore internal buffers (names starting with space) - Cache optimization prevents redundant set-cursor-color calls Behavior now: - Dashboard (read-only): Red cursor - Unmodified file: White cursor - Modified file: Green cursor - After save: White cursor Tests: - Added 9 integration tests in test-ui-cursor-color-integration.el - Tests verify hook installation, buffer switching, modification tracking - All 27 tests passing (18 unit + 9 integration) Integration tests catch issues that unit tests miss: - Unit tests verified state detection logic (✓) - Integration tests verify hooks fire at right times (✓ now) - Integration tests verify real buffer switching behavior (✓ now) Cleanup: - Removed debug code from init.el - Removed debug-cursor-color.el temporary file
