The `remind_sync` library was acting as a thin re-export layer. This
commit removes it entirely and moves the only non-trivial utility
(`show_error` for `Timedesc.Date.Ymd.error`) directly into
`bin/utils.ml`. Dead `[@@deriving show]` annotations on `rem`,
`week_first_day`, and `error` types are also removed.
- Add `simple_weekly` type and `weekly` field to `rem` record
- Add `exdate` field to `rem` for excluded dates
- Add `collect_exdates` collector to pipeline
- implement weekly `RRULE` handling with `BYDAY`, `INTERVAL`,
`COUNT`/`UNTIL`
- Add `render_weekly` to emit one `REM` per weekday with `UNTIL`/`*N`
- Replace `timedesc_of_date_or_datetime` with
`timedesc_of_utc_or_timestamp_local` in utils
- Refactor `get_exdates`/`get_rdates` to separate dates, datetimes and
periods; add debug logging per UID
- Wrap reminder output in try/catch in main; drop trailing newline
duplication
- Mark implemented predicates (P00–P05, P09, P12, P14) with ✅;
remove P18–P20 (ignored/deferred)
- Accept multiple positional arguments instead of a single required file
- Extract `read_file` helper to separate file reading from parsing
- Collect all valid reminders across files before printing
- Handle per-file errors gracefully without aborting the whole run
Add `yearly_simple_date` collector that detects simple yearly
recurrences (`RRULE:FREQ=YEARLY` with no extra constraints) and stores
the month/day pair in a new `simple_yearly` field on `Remind.rem`.
When rendering, events with `simple_yearly` set are emitted as
`REM <Month> <Day> MSG <summary>` instead of the full dated form.
Add `month_of_int` and `string_of_month` helpers in `Utils`, and update
the RRULE dataset comment with UIDs for easier debugging.
- Simplify `.ocamlformat` to use `default` profile with fewer overrides
- Extract shared types and utilities into a `remind_sync` library
(`icalendar_augmented`, `ptime_augmented`, `timedesc_augmented`,
`result_augmented`, `utf8`)
- Replace `eventTransformer.ml` and the predicate system in
`eventPredicates.ml` with a sequential collector pipeline
(`collect_uuid`, `collect_summary`, `collect_start_end_duration`,
etc.)
- Simplify `Remind.rem` to a flat record with `Timedesc` date/time
fields and replace `rem_to_string` with a leaner `string_of_rem`
- Add `separate_master_and_recurrence` and `get_recurrence_id` helpers
to `utils.ml`
- Wire `main.ml` to call `EventPredicates.remind_of_event` per UID group
and print results directly
- Remove `eventTransformer` module from `bin/dune` and enable the
`remind_sync` library dependency
- Change predicate return type from `bool` to `features list option` to
carry extracted event data (Summary, Day_start, Multi_day) alongside
match results
- Add `features` type with Generic_feature_presence, Summary, Day_start,
Multi_day variants
- Add P00 (has_summary) and P11 (override_events) predicates
- Remove large commented-out icalendar/ptime type definitions
- Refactor main.ml to group events by UID using a Map
- Add get_y_m_d_from_timedesc helper to Utils
- Add project scaffolding (dune, dune-project, opam, .ocamlformat)
- Implement basic parsing and handling of iCalendar events
- Add event predicates for common event types (all-day, timed,
recurrence, exceptions)
- Add transformation logic to map iCalendar events to Remind format
(stub implementation)
- Provide utilities for extracting event details and converting
dates/times
- Set up executable entrypoint and command-line interface using Cmdliner
- Include Remind event type definitions and helpers
