Coding own application for Gnome-shell Calendar / Evolution calendar

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1469 / 3 Years ago, sat, october 30, 2021, 3:06:20

I'm looking to write a calendar application in python that will interact with gnome-shell-calendar. I've asked around, and I was told that it uses evolution-data-sever

To get its information, I found out that there is a python-evolution python module that allows you to interact with the evolution server. But, that module has now been depreciated. Is-there another way to interact with the sever?

I've also noticed a process called gnome-shell-calendar-server. What's The difference between that and the evolution one?

Evolution Data Server 3.6 can be accessed with Python using gobject introspection. For this, gir1.2-edataserver-1.2 and gir1-2-ecalendar-1.2 also need to be installed.

For example, the following script will list all the events in all calendars in evolution-data-server.

#! /usr/bin/python

# -*- coding: utf-8 -*-



from gi.repository import ECalendar

from gi.repository import EDataServer



# Open a registry and get a list of all the calendars in EDS

registry = EDataServer.SourceRegistry.new_sync(None)

sources = EDataServer.SourceRegistry.list_sources(registry, EDataServer.SOURCE_EXTENSION_CALENDAR)



# Open each calendar containing events and get a list of all objects in them

for source in sources:

    client = ECalendar.CalClient.new(source, ECalendar.CalSourceType.EVENT)

    client.open_sync(False, None)



    # ret is true or false depending if events are found or not

    # values is a list of events

    ret, values = client.get_object_list_as_comps_sync("#t", None)

    if ret:

        for value in values:

            event = value.get_as_string()

            print event
