Add rrule from a string

[fluxxcode]

We have a rrule string that we want to add to an event.

At the moment this doesn't seem possible because the semicolons in the rrule strings are escaped with a backslash, invalidating the rrule.

Here is an example:

import icalendar

rrule_str = "FREQ=YEARLY;INTERVAL=10;BYMONTH=12"

event = Event()

# Both result in the same output
event.add("rrule", rrule_str)
event["rrule"] = rrule_str

Calling .to_ical escapes the rrule: RRULE:FREQ=YEARLY\;INTERVAL=10\;BYMONTH=12, making it invalid.

I think something like event.add_unescaped would be helpful.

Hi, thanks! It should somehow be possible to do that.

I would look for something like this:

from icalendar import vRecur

event["rrule"] = vRecur.from_ical("FREQ=YEARLY;INTERVAL=10;BYMONTH=12")

If you find a working example, could you add it to the documentation?
https://icalendar.readthedocs.io/en/latest/api.html#icalendar.prop.vRecur

I am sure others would like to use it, too..

Thank you for the answer!

event["rrule"] = vRecur.from_ical("FREQ=YEARLY;INTERVAL=10;BYMONTH=12")

works perfectly. I will create a PR for an example in the documentation.
