It's using a "vsyncdir" backend - if I've understood it correctly, that involves building a local copy of the calendar. The philosophy behind calendar-cli is slightly different, calendar-cli is supposed to be a simple cli-based caldav+ical client.

Writing something like "todo add make a calendar-cli system" or "calendar add 'tomorrow 15:40+2h' doctor appointment" is (for me) faster than navigating into some web calendar interface and add an item there. * Things that are outside the scope of the UI. Here is one of many tasks I'd like to do: "go through the work calendar, find all new calendar events that are outside office hours, check up with the personal calendar if there are potential conflicts, add some information at the personal calendar if appropriate", and vice versa - it has to be handled very manually if doing it through any normal calendar application as far as I know, but if having some simple CLI or python library I could easily make some interactive script that would help me doing the operation above. -I've been looking a bit around, all I could find was cadaver and CalDAVClientLibrary.

The third thing is journal ... but as far as I know, it's not much common to use caldav servers for keeping journals, the journal thing is not much tested nor much rich on features. + +There will be code refactorings in v1.0, applying quite some of the logic in the task management to the calendar management. + * calendar - access/modify a calendar - * subcommands: add, addics (for uploading events in ical format), agenda, delete + * subcommands: add, addics (for uploading events in ical format), agenda, delete, create (for creating a new calendar) * todo - access/modify a todo-list - * subcommands: add, list, edit, postpone, complete, delete + * subcommands: add, list, edit, postpone, complete, delete, addlist + +todo addlist: for creating a new task list. Most caldav servers don't make any difference between a task list and a calendar. Zimbra is an exception. addlist hasn't been tested as of version 0.12, perhaps it works, perhaps not) ### Event time specification -Supported in v0.8: +Supported in v0.12: * anything recognized by dateutil.parser.parse() * An iso time stamp, followed with the duration, using either + or space as separator. Duration is a number postfixed by s for seconds, m for minutes, h for hours, d for days, w for weeks and y for years (i.e. 2013-09-10T13:37+30d) +* ISO dates. For full day events, make sure to specify the duration in days. All of those would eventually be supported in future versions if it's not too difficult to achieve: * Two ISO timestamps separated by a dash (-) -* ISO dates without times (default duration will be one day, for two dates full days up to and including the end date is counted) * "tomorrow" instead of an ISO date * weekday instead of an ISO date (this seems supported already by dateutil.parser.parse) * clock time without the date; event will be assumed to start within 24 hours. -Alternatively, endtime or duration can be given through options (not supported as of 0.9) +Alternatively, endtime or duration can be given through options (not supported as of 0.12) + +### Getting out customized information through --todo-template and --event-template + +This is a string containing variables enclosed in curly braces, like "uid: {uid}". Full documentation of the available variables will be given in version 1.0. + +Particularly the uid can be useful, as one may want to use the uid for things like deleting events and postponing tasks. + +In the examples folder there is a task management script which will use the --todo-template to create a new shell script for postponing all overdue tasks. This shell script can then be edited interactively and run. + +### Task management + +With the todo-command, there are quite some options available (i.e. --categories, --limit, --todo-uid, etc) to select or filter tasks. Those are used by the commands list, edit, postpone, complete and delete. A typical use-case scenario is to first use the "list" command, tweak the filtering options to get a list containing the tasks one wants to operate with, and then use either edit, postpone, complete or delete.

(I considered a configuration file in .ini-format, having a "default"-section with default values for any global options, and optionally other sections for different CalDAV-servers. Asking a bit around for recommendations on config file format as well as location, I was told that the .ini-format is not a standard, I'd be better off using a standard like yaml, json or xml. Personally I like json a bit better than yaml - after consulting with a friend I ended up with json. Location ...
