SearXNG’s engines loader

Load and initialize the engines, see load_engines() and register engine_shortcuts.

usage:

load_engines( settings['engines'] )

searx.engines.engine_shortcuts

Simple map of registered shortcuts to name of the engine (or None).

engine_shortcuts[engine.shortcut] = engine.name

searx.engines.load_engine(engine_data: dict) → Engine | types.ModuleType | None

Load engine from engine_data.

Parameters:

engine_data (dict) – Attributes from YAML settings:engines/<engine>

Returns:

initialized namespace of the <engine>.

1. create a namespace and load module of the <engine>

2. update namespace with the defaults from ENGINE_DEFAULT_ARGS

3. update namespace with values from engine_data

If engine is active, return namespace of the engine, otherwise return None.

This function also returns None if initialization of the namespace fails for one of the following reasons:

• engine name contains underscore

• engine name is not lowercase

• required attribute is not set is_missing_required_attributes()

searx.engines.is_missing_required_attributes(engine)

An attribute is required when its name doesn’t start with _ (underline). Required attributes must not be None.

searx.engines.using_tor_proxy(engine: Engine | types.ModuleType)

Return True if the engine configuration declares to use Tor.

searx.engines.load_engines(engine_list)

usage: engine_list = settings['engines']
