""" VObject Overview ================ vobject parses vCard or vCalendar files, returning a tree of Python objects. It also provids an API to create vCard or vCalendar data structures which can then be serialized. Parsing existing streams ------------------------ Streams containing one or many L{Component<base.Component>}s can be parsed using L{readComponents<base.readComponents>}. As each Component is parsed, vobject will attempt to give it a L{Behavior<behavior.Behavior>}. If an appropriate Behavior is found, any base64, quoted-printable, or backslash escaped data will automatically be decoded. Dates and datetimes will be transformed to datetime.date or datetime.datetime instances. Components containing recurrence information will have a special rruleset attribute (a dateutil.rrule.rruleset instance). Validation ---------- L{Behavior<behavior.Behavior>} classes implement validation for L{Component<base.Component>}s. To validate, an object must have all required children. There (TODO: will be) a toggle to raise an exception or just log unrecognized, non-experimental children and parameters. Creating objects programatically -------------------------------- A L{Component<base.Component>} can be created from scratch. No encoding is necessary, serialization will encode data automatically. Factory functions (TODO: will be) available to create standard objects. Serializing objects ------------------- Serialization: - Looks for missing required children that can be automatically generated, like a UID or a PRODID, and adds them - Encodes all values that can be automatically encoded - Checks to make sure the object is valid (unless this behavior is explicitly disabled) - Appends the serialized object to a buffer, or fills a new buffer and returns it Examples -------- >>> import datetime >>> import dateutil.rrule as rrule >>> x = iCalendar() >>> x.add('vevent') <VEVENT| []> >>> x <VCALENDAR| [<VEVENT| []>]> >>> v = x.vevent >>> utc = icalendar.utc >>> v.add('dtstart').value = datetime.datetime(2004, 12, 15, 14, tzinfo = utc) >>> v <VEVENT| [<DTSTART{}2004-12-15 14:00:00+00:00>]> >>> x <VCALENDAR| [<VEVENT| [<DTSTART{}2004-12-15 14:00:00+00:00>]>]> >>> newrule = rrule.rruleset() >>> newrule.rrule(rrule.rrule(rrule.WEEKLY, count=2, dtstart=v.dtstart.value)) >>> v.rruleset = newrule >>> list(v.rruleset) [datetime.datetime(2004, 12, 15, 14, 0, tzinfo=tzutc()), datetime.datetime(2004, 12, 22, 14, 0, tzinfo=tzutc())] >>> v.add('uid').value = "randomuid@MYHOSTNAME" >>> print x.serialize() BEGIN:VCALENDAR VERSION:2.0 PRODID:-//PYVOBJECT//NONSGML Version 1//EN BEGIN:VEVENT UID:randomuid@MYHOSTNAME DTSTART:20041215T140000Z RRULE:FREQ=WEEKLY;COUNT=2 END:VEVENT END:VCALENDAR """ import base, icalendar, vcard from base import readComponents, readOne, newFromBehavior def iCalendar(): return newFromBehavior('vcalendar', '2.0') def vCard(): return newFromBehavior('vcard', '3.0')
