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('⧼lang⧽') 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

-- also enable debugging if debug is unspecified, and "nosup" is false debugging = debugging or ((debugging == nil) and not nosup)

local output = p._Ordinal( args[1], -- positive integer number lang, -- language args["style"], -- allows to set presentation style args["gender"], -- allows to specify gender (m, f, or n) nosup, -- set nosup to "y" to suppress superscripts debugging -- Set debug=y to output error messages )

-- Add maintenance category if (i18n.SchemeFromLang[lang] == nil) and debugging then output = output_cat(output, 'Pages with calls to Module Ordinal using an unsupported language') end

return output end


--[[ This function will add the appropriate ordinal suffix to a given integer.

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.

Error Handling: 

  Unless debug is true, any error results in value being echoed to the output.
