Okay, I had some time to work on it. For now, I am trying to figure out limitations and possible issues with different format. But so far, this script based on ics library works quite well with Nextcloud-generated ics files (everything in one file). I’ll leave it here for future reference:

from ics import Calendar

event_file = "myevent.ics"
task_file = "mytasks.ics"

print("====== EVENTS ======")

with open(event_file, 'r') as f:
    ics_text = f.read()

c = Calendar(ics_text)
for event in c.events:
    print(event.name)
    print(event.begin)
    print(event.all_day)
    print(event.description)
    print(event.status)
    print(event.classification)

print("====== TASKS ======")

with open(task_file, 'r') as f:
    ics_text = f.read()

c = Calendar(ics_text)
for task in c.todos:
    print(task.name)

And about the libraries, 2 of them were listed above in this thread, there is a third one, vobject.

• ics-py
  • Well documented
  • Maintained
  • But, too much issues like you said above
• icalendar
  • Partial documentation
  • Maintained
  • Use by Khal or Vdirsync projects, but with wrappers or forked because of limitations
  • The lack of some parts in the documentation make it hard to check what is missing actually
• vobject
  • Well documented
  • Not maintained for 4 years but still get PRs and issues. Apparently the maintainer is still in business in the calendars but stopped sharing updates.
  • Support VCARDs too, can be nice to parse birthdays
  • Support most feature lacking in the 2 other ones
  • A lot of ongoing issues and PRs that need to be assessed to see if it’s usable.

Something like https://github.com/sabre-io/vobject but not in PHP would have been nice.
