Tools to sync from CalDAV to Remind (dav2rem.py) and the other way round (rem2dav.py).

You need to have the Remind command line tool installed. For Debian/Ubuntu use:

$ sudo apt-get install remind

$ pip install remind-caldav

This will install all Python dependencies as well.

$ python3 setup.py install

There are a number of options how to provide the CalDAV password:

• Use a netrc(5) file (<domain> being the domain part of the CalDAV URL):

machine <domain> login <user> password <password>

• Use python-keyring with the CalDAV URL as the service.
• Providing a password on the command line. Note that this leaks into the environment.
• If no password is provided, the tools will ask for one.

Go to https://www.google.com/settings/security/lesssecureapps and enable "Access for less secure apps". This enables basic HTTP authentication as OAuth2 is not supported by python-caldav.

Where calid should be replaced by the "calendar ID" of the calendar to be accessed. This can be found through the Google Calendar web interface as follows: in the pull-down menu next to the calendar name, select Calendar Settings. On the resulting page the calendar ID is shown in a section labelled Calendar Address. The calendar ID for a user's primary calendar is the same as that user's email address.
