Class Method Details

.create(start = Time.now, fields = []) ⇒ Object

Create a new Vevent object. All events must have a DTSTART field, specify it as either a Time or a Date in start, it defaults to “now”

If specified, fields must be either an array of Field objects to add, or a Hash of String names to values that will be used to build Field objects. The latter is a convenient short-cut allowing the Field objects to be created for you when called like:

Vevent.create(Date.today, 'SUMMARY' => "today's event")

def Vevent.create(start = Time.now, fields=[])
  # TODO
  # - maybe events are usually created in a particular way? With a
  # start/duration or a start/end? Maybe I can make it easier. Ideally, I
  # would like to make it hard to encode an invalid Event.
  # - I don't think its useful to have a default dtstart for events
  # - also, I don't think dstart is mandatory
  dtstart = DirectoryInfo::Field.create('DTSTART', start)
  di = DirectoryInfo.create([ dtstart ], 'VEVENT')

  Vpim::DirectoryInfo::Field.create_array(fields).each { |f| di.push_unique f }

  new(di.to_a)
end

.create_yearly(date, summary) ⇒ Object

Creates a yearly repeating event, such as for a birthday.
