Data::ICal - Generates iCalendar (RFC 2445) calendar files
my $calendar = Data::ICal->new();
my $vtodo = Data::ICal::Entry::Todo->new();
# ... 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
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.)
Data::ICal is a subclass of Data::ICal::Entry; see its manpage for more
methods applicable to Data::ICal.
new [ data => $data, ] [ filename => $file ], [ vcal10 => $bool ]
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
If a filename or data argument is not passed, this just sets its
"VERSION" and "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
parse [ data => $data, ] [ filename => $file, ]
Parse a ".ics" file or string containing one, and populate $self with
Should only be called once on a given object, and will be automatically
called by "new" if you provide arguments to "new".
Returns $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 "error_message".
Returns "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 requires Class::Accessor, Text::vFile::asData,
MIME::QuotedPrint, and Class::ReturnValue.
BUGS AND LIMITATIONS
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.
