◆ fetch_traits()

searx.engines.archlinux.fetch_traits ( EngineTraits engine_traits )

Fetch languages from Archlinux-Wiki.  The location of the Wiki address of a
language is mapped in a :py:obj:`custom field
<searx.enginelib.traits.EngineTraits.custom>` (``wiki_netloc``).  Depending
on the location, the ``title`` argument in the request is translated.

.. code:: python

   "custom": {
     "wiki_netloc": {
       "de": "wiki.archlinux.de",
        # ...
       "zh": "wiki.archlinuxcn.org"
     }
     "title": {

        # ...
