"RRULE:" is missing #29

Closed DenisLobur closed 7 years ago

DenisLobur commented 7 years ago

It seems that lib-recur is missing substring "RRULE:" before any recurrent rule as in rfc5545 doc

That's by intention. The RRULE: string is not part of the actual recurrence rule. It's the name (including the delimiter char :) of the icalendar property that holds the recurrence rules of an event (or task). A properly layered icalendar library will return RRULE as the key and the actual rrule string (without RRULE:) as the value of that property. This library essentially supports the RECUR value type as specified in RFC 5545, section 3.3.10, hence the name. I know that the Goole rfc 2445 library accepts (or maybe even requires) this part, but in my opinion this is a bug (or design error, if you will).
