Take a set of CalDAV calendars and merge all their events into a single CalDAV calendar. Uses vdirsyncer. Run it as a cron job.
Clone the repo and create .env file in it:
CALDAV_URL=
CALDAV_USERNAME=
CALDAV_PASSWORD=
INPUT_CALENDARS=
OUTPUT_CALENDAR=
The input calendars envvar is a comma-separated list of CalDAV collection IDs, the output calendar is a single ID. Warning, the output calendar will be fully overwritten with the merged calendars.
Calendar IDs can each be prefixed with a comment string and a colon, to help keep them straight.
Install dependencies with Poetry or
equivalent following the versions in pyproject.toml, poetry.lock.
Execute
poetry run python -m calmerge
on a cron job with the desired frequency.
