Module:DemoTemplate

This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.

Usage

Simply place "#invoke:DemoTemplate|" before a call to a template. For example, {{#invoke:DemoTemplate|Convert|10|km|nmi|abbr=off}} yields the following:

Lua error in package.lua at line 80: module 'Module:No globals' not found.

This module handles both named and positional parameters as well as equals signs in both parameter names and values correctly, so this (for example) will work: {{#invoke:DemoTemplate|1x|1=Some parameter with an = sign in it}}

Lua error in package.lua at line 80: module 'Module:No globals' not found.

Note, however, that pipes, curly braces, etc. are not currently handled correctly by this module, so this (for example) will not work correctly: {{#invoke:DemoTemplate|1x|foo{{!}}bar}}

Lua error in package.lua at line 80: module 'Module:No globals' not found.

require('Module:No globals')

local newBuffer = require('Module:OutputBuffer')
local mt = {}

function mt.__index(t, title)
	return function(frame)
		local getBuffer, print, printf = newBuffer()
		printf('{{%s', title)
		local ipairsArgs = {}
		for k,v in ipairs(frame.args) do
			ipairsArgs[k] = true
			if string.find(v, '=', 1, true) then
				printf('|%d=%s', k, v)
			else
				printf('|%s', v)
			end
		end
		for k,v in pairs(frame.args) do
			if not ipairsArgs[k] then
				printf('|%s=%s', string.gsub(k, '=', '{{=}}'), v)
			end
		end
		print('}}')
		return string.format('<code>%s</code> &rarr; %s', mw.text.nowiki(getBuffer()), frame:expandTemplate{title = title, args = frame.args})
	end
end

return setmetatable({}, mt)
