calcurse-caldav
===============
calcurse-caldav is a simple Python script that can be used to synchronize
calcurse with a CalDAV server. Please note that the script is alpha software!
This means that:
* We are eagerly looking for testers to run the script and give feedback! If
you find any bugs, please report them to the calcurse mailing lists or to the
GitHub bug tracker. If the script works fine for you, please report back as
well!
* The script might still have bugs. Make backups, especially before running
calcurse-caldav for the first time!
Usage
-----
calcurse-caldav requires an up-to-date version of calcurse and a configuration
file located at ~/.calcurse/caldav/config. An example configuration file can be
found under contrib/caldav/config.sample in the calcurse source tree.
If you run calcurse-caldav for the first time, you need to provide the --init
argument. You can choose between the following initialization modes:
--init=keep-remote Remove all local calcurse items and import remote objects
--init=keep-local Remove all remote objects and push local calcurse items
--init=two-way Copy local objects to the CalDAV server and vice versa
For subsequent calcurse-caldav invocations, you don't need to specify any
additional parameters.
How It Works
------------
calcurse-caldav creates a so-called synchronization database at
~/.calcurse/caldav/sync.db that always keeps a snapshot of the last time the
script was executed. When running the script, it compares the objects on the
server and the local objects with that snapshot to identify items that were
added or deleted. It then
* downloads new objects from the server and imports them into calcurse,
* deletes local objects that no longer exist on the server,
* uploads objects to the server that were added locally,
* deleted objects from the server that were deleted locally,
* updates the synchronization database with the new snapshot.
Note that, since calcurse does not use unique identifiers for items, it cannot
keep track of moved/edited items. Thus, changing an item is equivalent to
deleting the old item and creating a new one.
