.. _using-datedataparser:
Using DateDataParser
--------------------
:func:`dateparser.parse` uses a default parser which tries to detect language
every time it is called and is not the most efficient way while parsing dates
from the same source.
:class:`DateDataParser <dateparser.date.DateDataParser>` provides an alternate and efficient way
to control language detection behavior.
The instance of :class:`DateDataParser <dateparser.date.DateDataParser>` caches the found
languages and will prioritize them when trying to parse the next string.
:class:`dateparser.date.DateDataParser` can also be initialized with known languages:
>>> ddp = DateDataParser(languages=['de', 'nl'])
>>> ddp.get_date_data('vr jan 24, 2014 12:49')
DateData(date_obj=datetime.datetime(2014, 1, 24, 12, 49), period='day', locale='nl')
>>> ddp.get_date_data('18.10.14 um 22:56 Uhr')
DateData(date_obj=datetime.datetime(2014, 10, 18, 22, 56), period='day', locale='de')
>>> ddp.get_date_data('11 July 2012')
DateData(date_obj=None, period='day', locale=None)
