     729Local names of languages
     730========================
     731
     732The ``get_language_info()`` function provides detailed information about
     733languages::
     734
     735    >>> form django.utils.translation import get_language_info
     736    >>> l = get_language_info('de')
     737    >>> print l['name'], l['name_local'], l['bidi']
     738    German Deutsch False
     739
     740The ``name`` and ``name_local`` attributes of the dictionary contain the name
     741of the language in English and the language itself, respectively.  The ``bidi``
     742attribute is True only for bi-directional languages.
     743
     744In templates, you can use special template tags or filters to retrieve the same
     745information. To get information about a single language, use the
     746``{% get_language_info %}`` tag::
     747
     748    {% get_language_info for LANGUAGE_CODE as lang %}
     749    {% get_language_info for "pl" as lang %}
     750
     751You can then access the information::
     752
     753    Language code: {{ lang.language_code }}<br />
     754    Name of language: {{ lang.name_local }}<br />
     755    Name in English: {{ lang.name }}<br />
     756    Bi-directional: {{ lang.bidi }}
     757
     758You can also use the ``{% get_language_info_list %}`` template tag to retrieve
     759information for a list of languages (e.g. active languages as specified in
     760``settings.LANGUAGES``).  See `The set_language redirect view`_ for an example
     761of how to display a language selector using ``{% get_language_info_list %}``.
     762
     763In addition to ``settings.LANGUAGES`` style nested tuples,
     764``{% get_language_info_list %}`` supports simple lists of language codes.  If
     765you do this in your view::
     766
     767  return render_to_response('mytemplate.html',
     768                            {'available_languages': ['en', 'es', 'fr']},
     769                            RequestContext(request))
     770
     771you can iterate those languages in the template::
     772
     773  {% get_language_info_list available_languages %}
     774  {% for l in available_languages %} ... {% endfor %}
     775
     776There are also simple filters available for convenience:
     777
     778    * ``{{ LANGUAGE_CODE|language_name }}``  ("German")
     779    * ``{{ LANGUAGE_CODE|language_name_local }}`` ("Deutsch")
     780    * ``{{ LANGUAGE_CODE|bidi }}`` (False)
     781
     782The source of the language information is the ``django.conf.language_info``
     783module.  If you add a new translation, you should run the
     784``django/bin/make-language-info.py`` script to insert the information for the
     785added language.
