An alternative which _might_ be a bit faster would be to ask iCal for
the 'open file alarms of events of calendars whose filepath is [URL of
the script file]'. This returns an AppleScript list of lists of lists,
the innermost lists of which contain either nothing or just the alarms
which trigger the script. Iterating through the lists should be faster
than iterating through the application and only the presented alarms
need be checked. The relevant calendars and events can be referenced
through the index values of the loop variables. As with Paul's outline,
this does _not_ work with repeated events.
on myEvent()
set now to (current date)
set leeway to 5 -- Allow, say, 5 seconds for the script to respond
to the alarm.
tell application "System Events" to set myUrl to URL of (path to me)
tell application "iCal" to set myInstances to (open file alarms of
events of calendars whose filepath is myUrl)
return result
--> A list containing lists corresponding to the calendars,
containing lists
--> corresponding to the events, containing nothing or matching alarm(s).
set evntCal_Indices to {}
repeat with c from 1 to (count myInstances)
set thisCal to item c of myInstances
repeat with e from 1 to (count thisCal)
set thisEvnt to item e of thisCal
repeat with alrm from 1 to (count thisEvnt)
tell application "iCal" to set timeDiff to (start date of
event e of calendar c) + (trigger interval of item alrm of thisEvnt) *
minutes - now
if (timeDiff > -leeway) and (timeDiff < leeway) then set end
of evntCal_Indices to {e, c}
end repeat
end repeat
end repeat
return evntCal_Indices -- event/calendar index pairs.
end myEvent
set candidates to myEvent()
--> {{11, 4}} -- One candidate found: event 11 of calendar 4.
