From fd1a5d308e730bad2936adb2384897bb620458be Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Fri, 14 Nov 2025 01:53:30 -0600 Subject: feat(ui): Add buffer modification state to color indicators MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change modeline filename and cursor colors to indicate buffer modification status, not just read-only/overwrite state. Color scheme changes: - White (#ffffff): Unmodified writeable buffer - Green (#64aa0f): Modified writeable buffer (unsaved changes) - Red (#f06a3f): Read-only buffer - Gold (#c48702): Overwrite mode active Previously: All writeable buffers were green regardless of modification Now: White when clean, green when dirty (better visual feedback) Implementation: - Updated cj/buffer-status-colors in user-constants.el: - Changed 'normal' → 'unmodified' (white) - Added new 'modified' state (green) - Updated state detection in modeline-config.el: - Now checks (buffer-modified-p) before defaulting to unmodified - Updated cursor color logic in ui-config.el: - Same state detection as modeline for consistency - Added after-change-functions hook for real-time updates - Added after-save-hook to update on save Priority order (highest to lowest): 1. Read-only (red) - takes precedence over everything 2. Overwrite mode (gold) - takes precedence over modified state 3. Modified (green) - buffer has unsaved changes 4. Unmodified (white) - default for clean writeable buffers Tests: - 18 comprehensive tests in test-ui-buffer-status-colors.el - Tests state detection logic and priority order - Tests color constant definitions and mappings - Tests integration with cursor and modeline - All tests passing 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- tests/test-ui-buffer-status-colors.el | 221 ++++++++++++++++++++++++++++++++++ 1 file changed, 221 insertions(+) create mode 100644 tests/test-ui-buffer-status-colors.el (limited to 'tests') diff --git a/tests/test-ui-buffer-status-colors.el b/tests/test-ui-buffer-status-colors.el new file mode 100644 index 00000000..bb905ad4 --- /dev/null +++ b/tests/test-ui-buffer-status-colors.el @@ -0,0 +1,221 @@ +;;;
