@oge-ui/scheduler-engine

Commercial package. Like @oge-ui/scheduler, this engine is source-available commercial software: free for evaluation, development and testing — a paid license is required for production use. No watermark, no runtime license checks. See LICENSE and ogeui.com/license.

The framework-free engine behind the OGE UI scheduler. Plain TypeScript, shipped as ESM + CJS, with no Angular or React import anywhere — both render layers, @oge-ui/scheduler (Angular) and @oge-ui/react-scheduler (React), run this one copy (ADR 0003: commercial engines live in per-family engine packages, never in the MIT @oge-ui/behavior).

You rarely install it directly: it arrives as a dependency of either render package.

What's inside

• Layout kernels — buildTimeGrid / buildMonthGrid view models, layoutDayColumn (transitive-overlap clusters with greedy column assignment), packLanes / buildMonthWeekLanes (all-day strip and month rows with "+N more" overflow), the timeline's transposed lane layout.
• Recurrence — parseRecurrenceRule / serializeRecurrenceRule for the documented RFC 5545 subset (FREQ DAILY/WEEKLY/MONTHLY/YEARLY, INTERVAL, COUNT ⊕ UNTIL, BYDAY, BYMONTHDAY, BYMONTH, BYHOUR, BYMINUTE, BYSETPOS, WKST), expandRecurrence in RFC order, iCalendar blocks with DTSTART / RDATE / EXDATE lines (RDATE adds occurrences without consuming COUNT), and UTC …Z stamps converted to local instants. Still rejected: TZID, BYYEARDAY, BYWEEKNO, BYSECOND, EXRULE, VALUE=PERIOD.
• Interaction — gesture math (proposeMove, proposeResize, the drag arithmetic of every view), the pointer-gesture machine (beginPointerGesture, shared from @oge-ui/behavior: 3px threshold, capture-phase Escape-cancel, touch long press) and the keyboard maps (timeGridCellKey, chipKey, timeGridChipCtrlKey, timelineBarCtrlKey).
• View models — day/week columns (per-resource split), month, timeline, agenda and year builders, aria-label and text formatters, the grid semantics helpers (dayWeekColumnHeaderText, monthColumnHeaderText, dayWeekCellSelected, monthCellSelected, schedulerGridReadOnly).
• Adaptive view — OgeSchedulerAdaptiveViewController switches to the agenda view below a container breakpoint and restores the previous view.
• OgeSchedulerCore — the shell machine: the working set, DataSource loads and write-through, the cancelable CRUD pipelines, occurrence vs. series routing, the editor model mapping and default form items, navigation, the built-in context menu state, live-region announcements and the reminder scan. It takes an OgeReactivityAdapter (signals in Angular, a versioned store in React), so its semantics exist once.
• Config — OGE_DEFAULT_SCHEDULER_CONFIG, the full OgeSchedulerMessages catalog and resolveOgeSchedulerConfig.

Every module with a decision in it has a spec beside it; src/index.spec.ts guards the barrel, which is both render layers' import surface.
