Data::ICal - Generates iCalendar (RFC 2445) calendar files
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 from scalar $calendar->add_entry($vtodo); print $calendar->as_string;
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 Apple's 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.)
Creates a new Data::ICal object.
If it is given a filename or data argument is passed, then this parses the content of the file or string into the object. If the
vcal10 flag is passed, parses it according to vCalendar 1.0, not iCalendar 2.0; this in particular impacts the parsing of continuation lines in quoted-printable sections.
If a filename or data argument is not passed, this just sets its
PRODID properties to "2.0" (or "1.0" if the
vcal10 flag is passed) and the value of the
product_id method respectively.
Returns a false value upon failure to open or parse the file or data; this false value is a Class::ReturnValue object and can be queried as to its
.ics file or string containing one, and populate
$self with its contents.
Should only be called once on a given object, and will be automatically called by
new if you provide arguments to
$self on success. Returns a false value upon failure to open or parse the file or data; this false value is a Class::ReturnValue object and can be queried as to its
VCALENDAR, its iCalendar entry name.
Returns the product ID used in the calendar's
PRODID property; you may wish to override this in a subclass for your own application.
According to the iCalendar standard, the following properties must be specified exactly one time for a calendar:
According to the iCalendar standard, the following properties may be specified at most one time for a calendar:
Data::ICal does not support time zone daylight or standard entries, so time zone components are basically useless.
While Data::ICal tries to check which properties are required and repeatable, this only works in simple cases; it does not check for properties that must either both exist or both not exist, or for mutually exclusive properties.
Data::ICal does not check to see if property parameter names are known in general or allowed on the particular property.
Data::ICal does not check to see if nested entries are nested properly (alarms in todos and events only, everything else in calendars only).
The only property encoding supported by Data::ICal is quoted printable.
There is no Data::ICal::Entry::Alarm base class.
