Calendar: Add Recurrent Events Support

About the Project

The goal of the project is to add support to recurrent events in GNOME Calendar.

Support for recurrent events already exists in Evolution calendar but it is lacking in GNOME Calendar. For example, right now, for a weekly repeating event, users have to manually add that event every week which is very inconvenient and time consuming.

Recurrence property will be added to GcalEvent in Calendar. A new GcalRecurrence structure will be introduced which will handle the recurrence part in GcalEvent using Evolution’s API. The Edit-dialog (mockup) will be modified accordingly.

What is Evolution?

Evolution is a calendar and a mailing client. Learn more about Evolution here.

Work left to do

1. Ensure proper removal of recurrences. (When a recurring event's property is changed to 'No Repeat', the recurrences do not get removed properly)
2. Extract the correct start date of the recurring event while making changes. (Right now the start date extracted is that of the recurrence and not of the first recurrence)

3. Adding test suites for loading GcalManager, Adding/Removing simple events.
