|    - :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, search):
 | |
|        search.result_container.suggestions.add('example')
 | |
|        return True
 | |
| 
 | |
| External plugins
 | |
| ================
 | |
| 
 | |
| SearXNG supports *external plugins* / there is no need to install one, SearXNG
 | |
| runs out of the box.  But to demonstrate; in the example below we install the
 | |
| SearXNG plugins from *The Green Web Foundation* `[ref]
 | |
| <https://www.thegreenwebfoundation.org/news/searching-the-green-web-with-searx/>`__:
 | |
| 
 | |
| .. code:: bash
 | |
| 
 | |
|    $ sudo utils/searxng.sh instance cmd bash
 | |
|    (searxng-pyenv)$ pip install git+https://github.com/return42/tgwf-searx-plugins
 | |
| 
 | |
| In the :ref:`settings.yml` activate the ``plugins:`` section and add module
 | |
| ``only_show_green_results`` from ``tgwf-searx-plugins``.
 | |
| 
 | |
| .. code:: yaml
 | |
| 
 | |
|    plugins:
 | |
|      ...
 | |
|      - only_show_green_results
 | |
|      ...
 | |
| 
 | |
| 
 | |
| 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. A plugin doesn't need to implement all the hooks.
 | |
| 
 | |
| 
 | |
| .. py:function:: pre_search(request, search) -> bool
 | |
| 
 | |
|    Runs BEFORE the search request.
 | |
| 
 | |
|    `search.result_container` can be changed.
 | |
| 
 | |
|    Return a boolean:
 | |
| 
 | |
|    * True to continue the search
 | |
|    * False to stop the search
 | |
| 
 | |
|    :param flask.request request:
 | |
|    :param searx.search.SearchWithPlugins search:
 | |
|    :return: False to stop the search
 | |
|    :rtype: bool
 | |
| 
 | |
| 
 | |
| .. py:function:: post_search(request, search) -> None
 | |
| 
 | |
|    Runs AFTER the search request.
 | |
| 
 | |
|    :param flask.request request: Flask request.
 | |
|    :param searx.search.SearchWithPlugins search: Context.
 | |
| 
 | |
| 
 | |
| .. py:function:: on_result(request, search, result) -> bool
 | |
| 
 | |
|    Runs for each result of each engine.
 | |
| 
 | |
|    `result` can be changed.
 | |
| 
 | |
|    If `result["url"]` is defined, then `result["parsed_url"] = urlparse(result['url'])`
 | |
| 
 | |
|    .. warning::
 | |
|       `result["url"]` can be changed, but `result["parsed_url"]` must be updated too.
 | |
| 
 | |
|    Return a boolean:
 | |
| 
 | |
|    * True to keep the result
 | |
|    * False to remove the result
 | |
| 
 | |
|    :param flask.request request:
 | |
|    :param searx.search.SearchWithPlugins search:
 | |
|    :param typing.Dict result: Result, see - :ref:`engine results`
 | |
|    :return: True to keep the result
 | |
|    :rtype: bool
