Previously, only numeric forms (1d, 1w, 1m, 1y) and plural word forms
(days, weeks, months, years) were supported for recurrence patterns.
The common adverbial forms (daily, weekly, monthly, yearly) would fail
with 'invalid recurrence pattern' error.
Now users can use natural language recurrence patterns:
- recur:daily -> 1 day interval
- recur:weekly -> 7 day interval
- recur:monthly -> 30 day interval
- recur:yearly -> 365 day interval
Added test coverage for all four new patterns.
- Add month name parsing (jan, january, feb, etc.) with year logic
- Add day+month parsing (21jan, Jan21, 21January, etc.) in all case variations
- Add period boundaries (sod, eod, sow, eow, som, eom, soy, eoy)
- Add special keywords (later, someday -> 2150-01-01)
- Add duration-as-date offset (2d, 3w, etc. means X from now)
- Add named duration aliases (daily, weekly, monthly, yearly)
- Enhance ParseRecurrencePattern to support min, sec, hrs and word forms
- Implement time-of-day parsing (mon:15:35, tomorrow:0800, 15:35)
- Add comprehensive test suite (50+ tests total)
- All tests passing
Issue 1: Fix recurrence calculation for overdue tasks
- Use completion date (End) as base for next instance, not original due date
- If task due Monday completed Wednesday, next is Wednesday+7d not Monday+7d
- Fallback to Due date if End is not set
- Update test to verify new behavior
Issue 2: Fix description parsing to work without quotes
- Add parseAddArgs() to extract description from non-modifier words
- Description = all words that don't start with +, -, or contain :
- Enables: opal add buy groceries +shop carrots → 'buy groceries carrots'
- Validate description is required (error if only modifiers)
- Validate recurring tasks require due date
Issue 3: Implement flexible command syntax
- Add preprocessArgs() to parse arguments before Cobra routing
- Detect command position and split filters (left) from modifiers (right)
- Rewrite os.Args so Cobra routes correctly
- Enable both 'opal 2 done' and 'opal done 2' syntax
- Commands without modifiers accept filters on either side
- Commands with modifiers enforce [filters] command [modifiers]
- Add confirmation for modify without filters (modifies all tasks)
All commands updated to use preprocessed ParsedArgs from context.
All tests passing (33 tests).
- Complete SpawnNextInstance() for creating recurring task instances
- Implement automatic next instance spawning on task completion
- Add support for 'until' date to expire recurrences
- Copy tags from template to new instances
- Add comprehensive recurrence tests (6 tests, all passing)
- Test pattern parsing, formatting, next due calculation
- Test end-to-end recurring task workflow
- Test expiration with until dates
