From da0bd6883a4032054aef4b59c338f60796a0fd99 Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Sun, 16 Nov 2025 18:09:17 -0600 Subject: feat(calendar-sync): Add automatic timezone detection and chronological sorting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented calendar-sync.el as a complete replacement for org-gcal, featuring: **Core Functionality:** - One-way sync from Google Calendar to Org (via .ics URL) - UTC to local timezone conversion for all event timestamps - Chronological event sorting (past → present → future) - Non-blocking sync using curl (works reliably in daemon mode) **Automatic Timezone Detection:** - Detects timezone changes when traveling between timezones - Tracks timezone offset in seconds (-21600 for CST, -28800 for PST, etc.) - Triggers automatic re-sync when timezone changes detected - Shows informative messages: "Timezone change detected (UTC-6 → UTC-8)" **State Persistence:** - Saves sync state to ~/.emacs.d/data/calendar-sync-state.el - Persists timezone and last sync time across Emacs sessions - Enables detection even after closing Emacs before traveling **User Features:** - Interactive commands: calendar-sync-now, calendar-sync-start/stop - Keybindings: C-; g s (sync), C-; g a (start auto-sync), C-; g x (stop) - Optional auto-sync every 15 minutes (disabled by default) - Clear status messages for all operations **Code Quality:** - Comprehensive test coverage: 51 ERT tests (100% passing) - Refactored UTC conversion into separate function - Clean separation of concerns (parsing, conversion, formatting, sorting) - Well-documented with timezone behavior guide and changelog **Migration:** - Removed org-gcal-config.el (archived in modules/archived/) - Updated init.el to use calendar-sync - Moved gcal.org to .emacs.d/data/ for machine-independent syncing - Removed org-gcal appointment capture template Files modified: modules/calendar-sync.el:442, tests/test-calendar-sync.el:577 Files created: data/calendar-sync-state.el, tests/testutil-calendar-sync.el Documentation: docs/calendar-sync-timezones.md, docs/calendar-sync-changelog.md 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- data/calendar-sync-state.el | 1 + 1 file changed, 1 insertion(+) create mode 100644 data/calendar-sync-state.el (limited to 'data/calendar-sync-state.el') diff --git a/data/calendar-sync-state.el b/data/calendar-sync-state.el new file mode 100644 index 00000000..3ada9d6b --- /dev/null +++ b/data/calendar-sync-state.el @@ -0,0 +1 @@ +((timezone-offset . -28800) (last-sync-time 26906 25621 571531 671000)) -- cgit v1.2.3
