Follow up of #2269 The script to update the descriptions of the engines does no longer work since PR #2269 has been merged. searx/engines/wikipedia.py ========================== 1. There was a misusage of zh-classical.wikipedia.org: - `zh-classical` is dedicate to classical Chinese [1] which is not traditional Chinese [2]. - zh.wikipedia.org has LanguageConverter enabled [3] and is going to dynamically show simplified or traditional Chinese according to the HTTP Accept-Language header. 2. The update_engine_descriptions.py needs a list of all wikipedias. The implementation from #2269 included only a reduced list: - https://meta.wikimedia.org/wiki/Wikipedia_article_depth - https://meta.wikimedia.org/wiki/List_of_Wikipedias searxng_extra/update/update_engine_descriptions.py ================================================== Before PR #2269 there was a match_language() function that did an approximation using various methods. With PR #2269 there are only the types in the data model of the languages, which can be recognized by babel. The approximation methods, which are needed (only here) in the determination of the descriptions, must be replaced by other methods. [1] https://en.wikipedia.org/wiki/Classical_Chinese [2] https://en.wikipedia.org/wiki/Traditional_Chinese_characters [3] https://www.mediawiki.org/wiki/Writing_systems#LanguageConverter Closes: https://github.com/searxng/searxng/issues/2330 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
