d Zy)r5   aL  Matches a regular expression and maps named groups in the pattern to
    datetime attributes using a function or overridden method.

    There are two points at which you can customize the behavior of this class,
    either by supplying functions to the initializer or overriding methods.

    * The ``modify`` function or ``modify_props`` method takes a ``Props``
      object containing the named groups and modifies its values (in place).
    * The ``fn`` function or ``props_to_date`` method takes a ``Props`` object
      and the base datetime and returns an adatetime/datetime.

        :param basedate: a datetime object representing the current time
            against which to measure relative dates. If you do not supply this
            argument, the plugin uses ``datetime.utcnow()``.
        :param dateparser: an instance of
            :class:`whoosh.qparser.dateparse.DateParser`. If you do not supply
            this argument, the plugin automatically uses
            :class:`whoosh.qparser.dateparse.English`.
        :param callback: a callback function for parsing errors. This allows
            you to provide feedback to the user about problems parsing dates.
        :param remove: if True, unparseable dates are removed from the token
            stream instead of being replaced with ErrorToken.
        :param free: if True, this plugin will install a filter early in the
            parsing process and try to find undelimited dates such as
            ``date:last tuesday``. Note that allowing this could result in
            normal query words accidentally being parsed as dates sometimes.
