"""Script to run SearXNG from terminal.
DON'T USE THIS SCRIPT!!
.. danger::
Be warned, using the ``standalone_searx.py`` won't give you privacy!
On the contrary, this script behaves like a SearXNG server: your IP is
exposed and tracked by all active engines (google, bing, qwant, ... ), with
every query!
.. note::
This is an old and grumpy hack / SearXNG is a Flask application with
client/server structure, which can't be turned into a command line tool the
way it was done here.
Getting categories without initiate the engine will only return `['general']`
>>> import searx.engines
... list(searx.engines.categories.keys())
['general']
>>> import searx.search
... searx.search.initialize()
... list(searx.engines.categories.keys())
['general', 'it', 'science', 'images', 'news', 'videos', 'music', 'files', 'social media', 'map']

.. code:: bash
