--------------------------------------------------------------------------------- Output template parameter functions-------------------------------------------------------------------------------
-- The results of these functions are substituted into parameters in the-- output template. The parameters look like $. Trying to use-- a parameter that doesn't have a function defined here will result in an-- error.---- The functions take a data table as a single argument. This table contains-- the following fields:-- * errors - a table of formatted error messages that were found when-- processing the input.-- * args - the table of arguments supplied by the user.-- * articles - an array of the article names found in the arguments.-- * authors - an array of the expanders/creators/writers/authors found in the-- arguments.-- * revisionUser - the user that last edited the page. As this module is only-- substituted, this is always the current user.-- * alts - an array of the ALT hooks found in the arguments.-- * title - the mw.title object for the current page.---- Template parameter functions should return a string, false, or nil.-- Functions returning false or nil will be treated as outputting the empty-- string "".
