How kud3n013/kalendar works

Kalendar is a local-first Linux calendar and task planner. The user edits events and tasks in the desktop UI; the app keeps them in its local data model and files, while optional calendar feeds and account sync provide external calendar data. The map includes the documented planning, task, calendar, settings, and sync capabilities. Several modules are only identified by the source index or README, so their internal behavior and unshown call paths are not expanded.

Main entry points: main.rs App orchestration · model.rs Events and tasks · mod.rs Sync coordination · ics.rs iCalendar feeds
