[ICS Reply] ICS patching core process #949

Closed Arsnael closed 5 months ago

Arsnael commented 5 months ago

Write a method that would take an ICS as an input file, being an invitation to a calendar event (METHOD: REQUEST), that would the transform it in output into a METHOD: REPLY ICS event with the attendance of the participant (accept / reject / maybe)

Note:

Example

Given I have this ics file as input:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Sabre//Sabre VObject 4.1.3//EN
CALSCALE:GREGORIAN
METHOD:REQUEST
BEGIN:VTIMEZONE
TZID:Europe/Paris
BEGIN:DAYLIGHT
TZOFFSETFROM:+0100
TZOFFSETTO:+0200
TZNAME:CEST
DTSTART:19700329T020000
RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=-1SU
END:DAYLIGHT
BEGIN:STANDARD

 omptetest15.linagora@avocat.fr
DTSTAMP:20240222T204008Z

END:VEVENT
END:VCALENDAR

Accepting the invitation might result in something like this:

BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
METHOD:REPLY
BEGIN:VTIMEZONE
TZID:Europe/Paris
BEGIN:DAYLIGHT
TZOFFSETFROM:+0100
