--[=[ This is an experiment to see what is required to consolodate all of the myriad {{lang-xx}} templates and their subtemplates into a single module with a data table {{lang-es}} has parameters: {{{1}}} text - required {{{link}}} or {{{links}}} defaults to 'yes' {{{lit}}} literal translation {{language with name}} has parameters: {{{1}}} iso language code - required {{{2}}} language name in English - superfluous? {{{3}}} text - required {{{4}}} or {{{lit}}} literal translation {{{link}}} or {{{links}}} set to 'no' disables '{{{2}} language' wikilinks {{{rtl}}} passed through to {{lang}} {{{nocat}}} passed through to {{lang}} {{lang}} has parameters: {{{1}}} iso language code - required {{{2}}} text - required {{{rtl}}} if set to any value, set dir="rtl" attribute and inserts ‎ after the </span> tag {{{nocat}}} if set to any value, disables categorization How it works now: 1. {{lang-es}} receives text as {{{1}}} to which it adds italic markup, sets |links to {{{link}}} or {{{links}}} or yes, sets |lit to {{{lit}}}, and calls {{language with name}}. {{{rtl}}} ignored for this example 2. {{language with name}} renders [[Spanish language|Spanish]] ({{{links}}} not set) or Spanish ({{{links}}} set) and calls {{lang}} 3. {{lang}} wraps the text in the <span lang="es">text</span> and adds categorization ]=] require('Module:No globals'); local getArgs = require('Module:Arguments').getArgs; --local lang_name_table = mw.loadData ('Module:Language/data/iana languages'); local lang_name_table = require ('Module:Language/name/data'); local p = {}; --[[--------------------------< I S _ S E T >------------------------------------------------------------------ Returns true if argument is set; false otherwise.
