Fixed issue with duplicate events
Switched from list comprehensions to generator expressions for better performance
Problems:
Date sorting not working as expected
- Correct setup of logging
- all inkycal-modules inherit from the given template
- Added basic, optional validation
- more code cleanups
- fixed a few minor bugs
* Switched from ics library to icalendar library to support (hopefully) all iCalendars
* Implemented authorisation data for protected icalendar urls (credit to Joshka!)
* Created class instead of single function
Might be buggy, therefore in alpha stage!
