2025-03-29[refactor] migrate plugins from "module" to class SXNGPluginMarkus Heiser
This patch brings two major changes: - ``Result.filter_urls(..)`` to pass a filter function for URL fields - The ``enabled_plugins:`` section in SearXNG's settings do no longer exists. To understand plugin development compile documentation: $ make docs.clean docs.live and read http://0.0.0.0:8000/dev/plugins/development.html There is no longer a distinction between built-in and external plugin, all plugins are registered via the settings in the ``plugins:`` section. In SearXNG, plugins can be registered via a fully qualified class name. A configuration (`PluginCfg`) can be transferred to the plugin, e.g. to activate it by default / *opt-in* or *opt-out* from user's point of view. built-in plugins ================ The built-in plugins are all located in the namespace `searx.plugins`. .. code:: yaml plugins: searx.plugins.calculator.SXNGPlugin: active: true searx.plugins.hash_plugin.SXNGPlugin: active: true searx.plugins.self_info.SXNGPlugin: active: true searx.plugins.tracker_url_remover.SXNGPlugin: active: true searx.plugins.unit_converter.SXNGPlugin: active: true searx.plugins.ahmia_filter.SXNGPlugin: active: true searx.plugins.hostnames.SXNGPlugin: active: true searx.plugins.oa_doi_rewrite.SXNGPlugin: active: false searx.plugins.tor_check.SXNGPlugin: active: false external plugins ================ SearXNG supports *external plugins* / there is no need to install one, SearXNG runs out of the box. - Only show green hosted results: https://github.com/return42/tgwf-searx-plugins/ To get a developer installation in a SearXNG developer environment: .. code:: sh $ git clone git@github.com:return42/tgwf-searx-plugins.git $ ./manage pyenv.cmd python -m \ pip install -e tgwf-searx-plugins To register the plugin in SearXNG add ``only_show_green_results.SXNGPlugin`` to the ``plugins:``: .. code:: yaml plugins: # ... only_show_green_results.SXNGPlugin: active: false Result.filter_urls(..) ====================== The ``Result.filter_urls(..)`` can be used to filter and/or modify URL fields. In the following example, the filter function ``my_url_filter``: .. code:: python def my_url_filter(result, field_name, url_src) -> bool | str: if "google" in url_src: return False # remove URL field from result if "facebook" in url_src: new_url = url_src.replace("facebook", "fb-dummy") return new_url # return modified URL return True # leave URL in field unchanged is applied to all URL fields in the :py:obj:`Plugin.on_result` hook: .. code:: python class MyUrlFilter(Plugin): ... def on_result(self, request, search, result) -> bool: result.filter_urls(my_url_filter) return True Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

2025-01-28[refactor] typification of SearXNG (initial) / result items (part 1)Markus Heiser
Typification of SearXNG ======================= This patch introduces the typing of the results. The why and how is described in the documentation, please generate the documentation .. $ make docs.clean docs.live and read the following articles in the "Developer documentation": - result types --> http://0.0.0.0:8000/dev/result_types/index.html The result types are available from the `searx.result_types` module. The following have been implemented so far: - base result type: `searx.result_type.Result` --> http://0.0.0.0:8000/dev/result_types/base_result.html - answer results --> http://0.0.0.0:8000/dev/result_types/answer.html including the type for translations (inspired by #3925). For all other types (which still need to be set up in subsequent PRs), template documentation has been created for the transition period. Doc of the fields used in Templates =================================== The template documentation is the basis for the typing and is the first complete documentation of the results (needed for engine development). It is the "working paper" (the plan) with which further typifications can be implemented in subsequent PRs. - https://github.com/searxng/searxng/issues/357 Answer Templates ================ With the new (sub) types for `Answer`, the templates for the answers have also been revised, `Translation` are now displayed with collapsible entries (inspired by #3925). !en-de dog Plugins & Answerer ================== The implementation for `Plugin` and `Answer` has been revised, see documentation: - Plugin: http://0.0.0.0:8000/dev/plugins/index.html - Answerer: http://0.0.0.0:8000/dev/answerers/index.html With `AnswerStorage` and `AnswerStorage` to manage those items (in follow up PRs, `ArticleStorage`, `InfoStorage` and .. will be implemented) Autocomplete ============ The autocompletion had a bug where the results from `Answer` had not been shown in the past. To test activate autocompletion and try search terms for which we have answerers - statistics: type `min 1 2 3` .. in the completion list you should find an entry like `[de] min(1, 2, 3) = 1` - random: type `random uuid` .. in the completion list, the first item is a random UUID Extended Types ============== SearXNG extends e.g. the request and response types of flask and httpx, a module has been set up for type extensions: - Extended Types --> http://0.0.0.0:8000/dev/extended_types.html Unit-Tests ========== The unit tests have been completely revised. In the previous implementation, the runtime (the global variables such as `searx.settings`) was not initialized before each test, so the runtime environment with which a test ran was always determined by the tests that ran before it. This was also the reason why we sometimes had to observe non-deterministic errors in the tests in the past: - https://github.com/searxng/searxng/issues/2988 is one example for the Runtime issues, with non-deterministic behavior .. - https://github.com/searxng/searxng/pull/3650 - https://github.com/searxng/searxng/pull/3654 - https://github.com/searxng/searxng/pull/3642#issuecomment-2226884469 - https://github.com/searxng/searxng/pull/3746#issuecomment-2300965005 Why msgspec.Struct ================== We have already discussed typing based on e.g. `TypeDict` or `dataclass` in the past: - https://github.com/searxng/searxng/pull/1562/files - https://gist.github.com/dalf/972eb05e7a9bee161487132a7de244d2 - https://github.com/searxng/searxng/pull/1412/files - https://github.com/searxng/searxng/pull/1356 In my opinion, TypeDict is unsuitable because the objects are still dictionaries and not instances of classes / the `dataclass` are classes but ... The `msgspec.Struct` combine the advantages of typing, runtime behaviour and also offer the option of (fast) serializing (incl. type check) the objects. Currently not possible but conceivable with `msgspec`: Outsourcing the engines into separate processes, what possibilities this opens up in the future is left to the imagination! Internally, we have already defined that it is desirable to decouple the development of the engines from the development of the SearXNG core / The serialization of the `Result` objects is a prerequisite for this. HINT: The threads listed above were the template for this PR, even though the implementation here is based on msgspec. They should also be an inspiration for the following PRs of typification, as the models and implementations can provide a good direction. Why just one commit? ==================== I tried to create several (thematically separated) commits, but gave up at some point ... there are too many things to tackle at once / The comprehensibility of the commits would not be improved by a thematic separation. On the contrary, we would have to make multiple changes at the same places and the goal of a change would be vaguely recognizable in the fog of the commits.

2024-07-14[mod] revision of the settings_loaderMarkus Heiser
The intention of this PR is to modernize the settings_loader implementations. The concept is old (remember, this is partly from 2014), back then we only had one config file, meanwhile we have had a folder with config files for a very long time. Callers can now load a YAML configuration from this folder as follows :: settings_loader.get_yaml_cfg('my-config.yml') - BTW this is a fix of #3557. - Further the `existing_filename_or_none` construct dates back to times when there was not yet a `pathlib.Path` in all Python versions we supported in the past. - Typehints have been added wherever appropriate At the same time, this patch should also be downward compatible and not introduce a new environment variable. The localization of the folder with the configurations is further based on: SEARXNG_SETTINGS_PATH (wich defaults to /etc/searxng/settings.yml) Which means, the default config folder is `/etc/searxng/`. ATTENTION: intended functional changes! If SEARXNG_SETTINGS_PATH was set and pointed to a not existing file, the previous implementation silently loaded the default configuration. This behavior has been changed: if the file or folder does not exist, an EnvironmentError exception will be thrown in future.
