local p = {} --[[ Ordinal This function converts an integer value into a numeral followed by ordinal indicator. The output string might contain HTML tags unless you set nosup=y. Usage:

- uses the caller's parameters Parameters 1: Positive integer number. lang: language style: Presentation style. Different options for different languages. In English there is "style=d" adding -d suffixes to all numbers. gender: Gender is used in French and Polish language versions. Genders: m for male, f for female and n for neuter. nosup: Set nosup=y to display the ordinals without superscript. debug: Set debug=y to output error messages. Error Handling: Unless debug=y, any error results in parameter 1 being echoed to the output. This reproduces the behavior of the original Ordinal template. ]] function p.Ordinal( frame ) -- if no argument provided than check parent template/module args local args = frame.args if args[1]==nil then args = frame:getParent.args end -- if we don't have a specified language, attempt to use the user's language local lang = args.lang if not lang or lang == '' or not mw.language.isValidCode( lang ) then lang = frame:preprocess('') end local nosup = yesno(args["nosup"] or '', false) -- nosup can be true or false local debugging = yesno(args["debug"], false) -- debugging can be nil, true, or false

Parameters input: Numeral as a positive integer or string. lang: Language code as a string (e.g. 'en', 'de', etc.). style: Presentation style as a string (e.g. 'd', 'roman', etc.). gender: Gender as a string ('m', 'f', 'n'). Use empty string '' to leave gender unspecified. nosup: Boolean, set to true to force the ordinals to display without superscript. debug: Boolean, set to true to output error messages.
