Module:TNT

-- -- INTRO: (!!! DO NOT RENAME THIS PAGE !!!) -- This module allows any template or module to be copy/pasted between -- wikis without any translation changes. All translation text is stored -- in the global Data:*.tab pages on Commons, and used everywhere. -- -- ATTENTION: -- Please do NOT rename this module - it has to be identical on all wikis. -- This code is maintained at https://www.mediawiki.org/wiki/Module:TNT -- Please do not modify it anywhere else, as it may get copied and override your changes. -- Suggestions can be made at https://www.mediawiki.org/wiki/Module_talk:TNT -- -- DESCRIPTION: -- The "msg" function uses a Commons dataset to translate a message -- with a given key (e.g. source-table), plus optional arguments -- to the wiki markup in the current content language. -- Use lang=xx to set language. Example: -- -- -- -- -- The "doc" function will generate the <templatedata> parameter documentation for templates. -- This way all template parameters can be stored and localized in a single Commons dataset. -- NOTE: "doc" assumes that all documentation is located in Data:Templatedata/* on Commons. -- -- -- uses https://commons.wikimedia.org/wiki/Data:Templatedata/Graph:Lines.tab -- if the current page is Template:Graph:Lines/doc --
