[Python-de] icalview

18 May 2018

      Ich hab ein kleines Script namens icalview (Quelle vergessen), das in mutt
eingebunden bisher zuverlaessig Outlook Kalender Attachments anzeigte.

Neuere Outlook Versionen verwenden ein Kalenderformat, bei dem icalview
ein falsches Datum berechnet: 2 h zu spaet.

Hier ist icalview:

#!/usr/bin/python2
import sys

import ics   # pip install ics
import arrow # pulled in with ics, else pip install arrow

cal = ics.Calendar(sys.stdin.read().decode('utf-8'))

tz = arrow.now().tzinfo
tzformat = 'ddd DD MMM HH:mm'
tzformat = 'YYYY-MM-DD HH:mm:ss'

for event in cal.events:
    extra = {}
    for item in event._unused:
        if not isinstance(item, ics.parse.ContentLine):
            continue
        try:
            extra[item.name.lower()] = item.value
        except:
            print item
            raise
    print "Event:    ", event.name.encode('utf-8')
    print "Status:   ", extra['status'].title()
    print "Organiser:", extra['organizer'].encode('utf-8')
    print "Starts:   ", event.begin.to(tz).format(tzformat), "(local time)"
    print "Ends:     ", event.end.to(tz).format(tzformat)
    print "Location: ", event.location.encode('utf-8')
    print "Description:"
    print (event.description or u'').encode('utf-8')

Und hier ein Kalendereintrag den icalview falsch anzeigt (Beginn 12:30
statt 10:30):
