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.
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
If a calname is passed, sets x-wr-calname to the given string. Although not
specified in RFC2445, most calendar software respects x-wr-calname as the
displayed name of the calendar.
If the "rfc_strict" flag is set to true, will require Data::ICal to
include UIDs, as per RFC2445:
188.8.131.52 Unique Identifier
... The property MUST be specified in the "VEVENT", "VTODO",
"VJOURNAL" or "VFREEBUSY" calendar components"
If the "auto_uid" flag is set to true, will automatically generate a
default UID for each type which requires it, based on the RFC-suggested
algorithm. Explicitly-set UID attributes will override this auto-generated
If a filename or data argument is not passed, this just sets the object's
"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 its
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
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.
