- :ref:`plugins generic`
Plugins can extend or replace functionality of various components of searx.
Example plugin
==============
.. code:: python
name = 'Example plugin'
description = 'This plugin extends the suggestions with the word "example"'
default_on = False # disabled by default
js_dependencies = tuple() # optional, list of static js files
css_dependencies = tuple() # optional, list of static css files
# attach callback to the post search hook
# request: flask request object
# ctx: the whole local context of the post search hook
def post_search(request, ctx):
ctx['search'].suggestions.add('example')
return True
External plugins
================
External plugins are standard python modules implementing all the requirements of the standard plugins.
Plugins can be enabled by adding them to :ref:`settings.yml`'s ``plugins`` section.
Example external plugin can be found `here <https://github.com/asciimoo/searx_external_plugin_example>`_.
Register your plugin
====================
To enable your plugin register your plugin in
searx > plugin > __init__.py.
And at the bottom of the file add your plugin like.
``plugins.register(name_of_python_file)``
Plugin entry points
===================
Entry points (hooks) define when a plugin runs. Right now only three hooks are
implemented. So feel free to implement a hook if it fits the behaviour of your
plugin.
Pre search hook
---------------
Runs BEFORE the search request. Function to implement: ``pre_search``
Post search hook
----------------
Runs AFTER the search request. Function to implement: ``post_search``
Result hook
-----------
Runs when a new result is added to the result list. Function to implement:
``on_result``
