bug#5433: calendar: ical export

[emacs user]

In GNU Emacs 23.1.91.4 (i386-apple-darwin9.8.0, NS apple-appkit-949.54) of 2010-01-16 on Windowing system distributor `Apple', version 10.3.949 configured using `configure  '--with-ns' '--without-x''
it seems that the export of calendar to ical format does not include the exporting of alarms.  I could be wrong, but perhaps what's missing is something like
BEGIN:VALARMX-WR-ALARMUID:C095B897-11FE-4D33-85E8-A933A67B1147ACTION:AUDIOTRIGGER:-PT15MATTACH;VALUE=URI:BassoEND:VALARM

icalendar.el ignores VALARM components during import and does not generate
them during export.

In iCalendar a VALARM is part of a VEVENT.  In Emacs the equivalent of a
VEVENT is a diary entry and the equivalent of a VALARM would be an
appointment notification. An appointment is generated (via
appt-make-list etc.) from a diary entry but it is not part of it.

icalendar import and export converts a diary file from and to an ical
file. Appointments are (currently) not involved.

There appears to be no obvious solution how to implement VALARM support.
(One could add a VALARM to each exported VEVENT scheduled 10 minutes or
so before the event. But that would be rather stupid.)

Any suggestions?

OK. I'll add something like newsticker-autocreate-valarm with possible
values 'audio, 'display and nil as well as
newsticker-autocreate-valarm-advance. 

As soon as I find the time.

Best,
Ulf

Ooops! Make that "icalendar-autocreate-...".

[Ulf Jasper]

Finally, there is a new variable `icalendar-export-alarms' for enabling
and configuring export of alarms.  I just committed it to the trunk.
So, if you are still interested, please try it.

Sorry for the delay!
