2025-09-03[mod] addition of various type hints / tbcMarkus Heiser
- pyright configuration [1]_ - stub files: types-lxml [2]_ - addition of various type hints - enable use of new type system features on older Python versions [3]_ - ``.tool-versions`` - set python to lowest version we support (3.10.18) [4]_: Older versions typically lack some typing features found in newer Python versions. Therefore, for local type checking (before commit), it is necessary to use the older Python interpreter. .. [1] https://docs.basedpyright.com/v1.20.0/configuration/config-files/ ..

2025-01-28[refactor] typification of SearXNG / EngineResultsMarkus Heiser
In [1] and [2] we discussed the need of a Result.results property and how we can avoid unclear code. This patch implements a class for the reslut-lists of engines:: searx.result_types.EngineResults A simple example for the usage in engine development:: from searx.result_types import EngineResults ... def response(resp) -> EngineResults: res = EngineResults() ... res.add( res.types.Answer(answer="lorem ipsum ..", url="https://example.org") ) ... return res [1] https://github.com/searxng/searxng/pull/4183#pullrequestreview-257400034 [2] https://github.com/searxng/searxng/pull/4183#issuecomment-2614301580 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.

2023-03-24[mod] DuckDuckGo: reversed engineered & upgrade to data_type: traits_v1Markus Heiser
Partial reverse engineering of the DuckDuckGo (DDG) engines including a improved language and region handling based on the enigne.traits_v1 data. - DDG Lite - DDG Instant Answer API - DDG Images - DDG Weather docs/src/searx.engine.duckduckgo.rst: Online documentation of the DDG engines (make docs.live) searx/data/engine_traits.json Add data type "traits_v1" generated by the fetch_traits() functions from: - "duckduckgo" (WEB), - "duckduckgo images" and - "duckduckgo weather" and remove data from obsolete data type "supported_languages". searx/autocomplete.py: Reversed engineered Autocomplete from DDG. Supports DDG's languages. searx/engines/duckduckgo.py: - fetch_traits(): Fetch languages & regions from DDG. - get_ddg_lang(): Get DDG's language identifier from SearXNG's locale. DDG defines its languages by region codes. DDG-Lite does not offer a language selection to the user, only a region can be selected by the user. - Cache ``vqd`` value: The vqd value depends on the query string and is needed for the follow up pages or the images loaded by a XMLHttpRequest (DDG images). The ``vqd`` value of a search term is stored for 10min in the redis DB. - DDG Lite engine: reversed engineered request method with improved Language and region support and better ``vqd`` handling. searx/engines/duckduckgo_definitions.py: DDG Instant Answer API The *instant answers* API does not support languages, or at least we could not find out how language support should work. It seems that most of the features are based on English terms. searx/engines/duckduckgo_images.py: DDG Images Reversed engineered request method. Improved language and region handling based on cookies and the enigne.traits_v1 data. Response: add image format to the result list searx/engines/duckduckgo_weather.py: DDG Weather Improved language and region handling based on cookies and the enigne.traits_v1 data.
