Data::ICal is a Perl module that generates iCalendar (RFC 2445) calendar files.

SYNOPSIS

use Data::ICal;

my $calendar = Data::ICal->new();

my $vtodo = Data::ICal::Entry::Todo->new();
$vtodo->add_properties(
# ... see Data::ICal::Entry::Todo documentation
);

# ... or

$calendar = Data::ICal->new(filename => foo.ics); # parse existing file
$calendar = Data::ICal->new(data => BEGIN:VCALENDAR...); # parse existing file


$calendar->add_entry($vtodo);

print $calendar->as_string;

# Or, if youre printing to something you want google to read:
print $calendar->as_string(fold => 0);

A Data::ICal object represents a VCALENDAR object as defined in the iCalendar protocol (RFC 2445, MIME type "text/calendar"), as implemented in many popular calendaring programs such as Apples iCal.

Each Data::ICal object is a collection of "entries", which are objects of a subclass of Data::ICal::Entry. The types of entries defined by iCalendar (which refers to them as "components") include events, to-do items, journal entries, free/busy time indicators, and time zone descriptors; in addition, events and to-do items can contain alarm entries. (Currently, Data::ICal only implements to-do items and events.)
Data::ICal is a subclass of Data::ICal::Entry; see its manpage for more methods applicable to Data::ICal.
