Calendar via @nbtca/nbtcal + activity heatmap#23
Merged
Conversation
- Replace inline ICS fetch+parse in calendar.ts with loadCalendar() from @nbtca/nbtcal; recurring events are now included via nbtcal's recurrence expansion - Add toDisplayEvent() mapping CalendarEvent -> prompt's Event type - Add fetchHeatmapBuckets() helper for trailing-year heatmap data - Add calendar-heatmap.ts: pure GitHub-contributions-style grid renderer (7 weekday rows × ~53 week columns, unicode glyphs with ASCII fallback, month labels via Intl.DateTimeFormat, localized legend) - showCalendar() renders heatmap header above the events table - Wire --heatmap flag to events command (--json prints JSON buckets, plain prints the grid; takes precedence over --today/--next) - Add vitest unit tests for renderHeatmap and toDisplayEvent - Extend test-cli.sh smoke test to cover events --heatmap

Summary
Swaps the calendar feature's data layer to @nbtca/nbtcal and adds a terminal activity heatmap.
fetchEvents()now uses@nbtca/nbtcal(loadCalendar().upcoming()) instead of inlineical.jsparsing. This fixes recurring (RRULE) events being silently dropped — e.g. the biweekly NWDC meetings now appear. All-day events render with no time.events --heatmapflag and an auto heatmap header in the interactive calendar view: a GitHub-contributions-style grid (7 weekday rows × ~53 week columns, trailing 12 months) built onnbtcal.heatmap(). ASCII fallback + color, host-timezone-independent layout.ical.jsdropped from direct deps (comes via nbtcal);vitestadded with 17 unit tests for the event mapper and heatmap renderer.Test plan
