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.
 --
 -- SEE: https://www.mediawiki.org/wiki/Multilingual_Templates_and_Modules
 --
 -- 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:
 --
 -- {{#invoke:TNT | msg
 -- | I18n/Template:Graphs.tab <!-- https://commons.wikimedia.org/wiki/Data:I18n/Template:Graphs.tab -->
 -- | source-table <!-- uses a translation message with id = "source-table" -->
 -- | param1 }} <!-- optional parameter -->
 --
 --
 -- 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.
 --
 -- {{#invoke:TNT | doc | Graph:Lines }}
 -- uses https://commons.wikimedia.org/wiki/Data:Templatedata/Graph:Lines.tab
 -- if the current page is Template:Graph:Lines/doc
