Module:Template link

-- This module implements template link templates like, undefined and that take many parameters. -- The module attempts to display named parameters as best it can, although the order will not be preserved. -- Templates that take only one or two parameters, such as undefined, are not implemented, as they will give -- better performance as regular templates. local getArgs = require('Module:Arguments').getArgs local p = {} local function makeInvokeFunction(funcName) return function (frame) local args = getArgs(frame, {trim = false, removeBlanks = false}) return p[funcName](args) end end function p.constructInvocation(targs, data) -- Builds a template invocation from the template args (targs). -- The algorithm is a modified version of the one used in Module:Unsubst. local nowiki = mw.text.nowiki -- If this is used we will call it for every argument, so making it local to improve performance. local cleanVal if data.nowiki then cleanVal = function (v) return nowiki(v) end else cleanVal = function (v) return v		end end -- Define the most common escaped characters. local pipe = '&#124;' local equals = '&#61;' local leftBrackets = '&#123;&#123;' local rightBrackets = '&#125;&#125;' -- Work out what the template link should be. local template = data.template if not template then error('Template name not specified', 2) end if data.link then template = mw.ustring.format('%s', template, template) end -- Process numbered args. local ret = leftBrackets .. template for k, v in ipairs(targs) do		if string.find(v, '=', 1, true) then -- Likely something like 1=foo=bar, so we need to do it as a named arg. break end ret = ret .. pipe .. cleanVal(v) targs[k] = nil end -- Process named args. for k, v in pairs( targs ) do ret = ret .. pipe .. cleanVal(k) .. equals .. cleanVal(v) end return ret .. rightBrackets end return p
