Module:Languages - Wikimedia Commons (original) (raw)

Supported languages (mappings in "MediaWiki:Lang/code" for {{int:lang}}, and their current native names)

Note that as of 2020-10-18, there's a new bug in Scribunto, which causes the standard "table.sort()" function to no longer accept a standard comparison function. Now when "table.sort()" fails, the error is correctly catched (instead of producing a visible error), but the list may not be sorted correctly (temporarily) in some cases. The bug is tracked and corrected in Mediawiki but waiting to be deployed with the fix. Nothing will need to be changed (using "perror()" will then no longer have any effect, it is just needed for now and the bug was not a bug of this module which was properly tested and sudddently failed unexpectedly). Thanks.

language_subpages( frame, transform, options ) Parameters frame: The frame that was passed to the method invoked. The first argument or the page argument will be respected. transform: A transform function. Example: function( basepagename, subpagename, code, langname ) end options: An object with options. Example: { abort= { on=function() end, time=0.8 } } Following options are available: abort: Aborts iterating over the subpages if one of the conditions is met. If the process is aborted, nil is returned! on: Function to be called if an abort-condition was met. cycles: The maximum number of subpages to run over. time: Maximum time to spend running over the subpages.

¯¯¯¯¯¯¯ Page.subpages() no longer works because it attempted to parse the HTML content generated by calling the parser function "Special:Prefixindex:" which is no longer expanded in Lua but converted to a "stripped tag" (containing a unique identifier surrounded by ASCII DEL characters) representing the tag name and its parameters. The actual expansion of stripped tags can no longer be performed in Lua. Now unstripping these tags just kills ALL these tags (except "wiki" tags) instead of performing their expansion by running the extension code. Only MediaWiki can unstrip these tags in texts after they have been returned by Lua. For this reason, page.subpages() is now completely empty (Module:Page no longer works). This cannot be bypassed, except by using a Scribunto extension library if lifting the limits set by mw.unstrip. Note that "Special:Prefixindex:" is also costly, even if it just requires a single database query to get all subpages, instead of one costly #ifexist or one costly mw.title() property reading per tested subpage to know if it exists. For now there's still no reliable way to get a list of subpages, or performing queries similar to the [[Special:Prefixindex]] page or list members of a category like when viewing a category page. Ideally, there should exist a method for such queries on Title objects returned by the mw.title library; but for now there's none. In Lua now, the only expansion possible with an immediate effect is the expansion of standard templates, all special tags or special pages, or parser function extensions do not work (Only the #expr parser function is supported by using an external Scribunto library). --]==] for pg in page.subpages( title, { ignoreNS=true } ) do if abort.cycles then abort.cycles = abort.cycles - 1 if 0 == abort.cycles then return ac() end end if abort.time then if (os.clock() - clock) > abort.time then return ac() end end if mw.ustring.len( pg ) <= 12 then langcode = string.lower( pg ); langname = fetch( langcode ); if langname ~= '' then table.insert( pages, transform( title, pg, langcode, langname ) ); end end end return pages; end return {}; end

--[=[ forEachLanguage

This function iterates over all language codes known to MediaWiki based on a maintained list replacing patterns in a pattern-string for each language

Usage {{#invoke:Languages|forEachLanguage |pattern=patternstring |before=string to insert before iteration |after=string added after iteration |sep=separator string between iterations |inLang=langcode used for lnTrPandlnTrP and lnTrPandlnTrUC1 }}

Parameters pattern: A pattern string which is processed for each language and which is concatenated at the end and returned as one string before: A string that is inserted before the concatenated result after: A string that is inserted after the concatenated result sep: A string that is inserted between each line created from the pattern while iterating (like ProcessedPattern_sep_ProcessedPattern_sep_ProcessedPattern) inLang: Langcode to use for lnTrPandlnTrP and lnTrPandlnTrUC1 preprocess: if set to a non-empty value, the output will be preprocessed before being returned.

Warning The output is still not prepreprocessed by default: so parser functions and magic keywords generated by the pattern are still not executed and replaced, and template transclusions are still not expanded (see examples in other functions in this module). When using this function directly from a MediaWiki page or template, this means it is only possible to use patterns generating basic MediaWiki formatting or HTML tags. It you want the output to be preprocessed (in the given frame), set the preprocess parameter to a non-empty string.

Patterns $lc - language code such as en or de $lnP - language name in own language (autonym) $lnUC1 - language name in own language (autonym), first letter upper case $lnTrP - language name translated to the language requested by language code passed to inLang $lnTrUC1 - language name translated to the language requested by language code passed to inLang, first letter upper case
