ya3 wants to be a simple tool helping you to organise your appointments. It is
far away from being finished.
-ya3 uses Charl Botha's ical2vcal to read and write calendar files (vCal). See
-http://cpbotha.net/2007/04/26/google-calendar-to-palm-desktop-conversion/ and
-http://code.google.com/p/ical2vcal/ for more information.
-
For licensing information see LICENSE.txt .
Features
~~~~~~~~
- Reading all vCal files from a directory and spit out appointments of the next
few days on stdout.
+- Creation of new appointments
Features to be implemented
~~~~~~~~~~~~~~~~~~~~~~~~~~
-- Create new appointments.
-- Change existing appointments.
-- Delete appointments.
- Support for recurrence (like birthdays).
- ...
+Requirements
+~~~~~~~~~~~~
+- Python3 (and Python2!!! :-o)
+- Python dateutil
+- Python vobject
+
Installation and setup
~~~~~~~~~~~~~~~~~~~~~~
-First of all, python is needed.
-
-Second, get ya3 via git:
+Get ya3 and place it where you like:
$ cd /path/where/ya3/shall/be/put
$ git pull .... ya3
-Third, get ical2vcal via svn:
-$ cd ya3/ical2vcal
-$ svn checkout http://ical2vcal.googlecode.com/svn/trunk/ .
-ACHTUNG: URL veraltet. Siehe https://code.google.com/archive/p/ical2vcal/
-
-Fourth, copy and edit configuration (not yet implemented):
-$ mkdir -p -m 0700 $HOME/.ya3/calendars
-$ cp /path/where/ya3/shall/be/put/ya3/config.template $HOME/.ya3/
+Edit configuration in config.py to fit your needs.
Usage
~~~~~
-$ ya3 <vcal file>
+$ create-appointment.py
-Future plans:
-$ ya3 -g [date from[-date to]]
+$ ya3 <vcal file>
Example
