Cách sử dụng[sửa mã nguồn]

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

{{Convert|10|km|nmi|abbr=off}} → 10 kilômét (5,4 hải lý)

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: {{#gọi:DemoTemplate|echo|1=Some parameter with an = sign in it}}

{{echo|1=Some parameter with an = sign in it}} → Some parameter with an = sign in it

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

{{echo|foo|bar}} → foo

			ipairsArgs[k] = true
			printf('|%s', v)
		for k,v in pairs(frame.args) do
			if not ipairsArgs[k] then
				printf('|%s=%s', string.gsub(k, '=', '{{=}}'), v)
		local buffer = getBuffer()
		-- rather than calling expandTemplate with the title and args we have, call preprocess, so that our code example will always match our output, even in the cases of pipes or other things we should have escaped but didn't
		return string.format('<code>%s</code> &rarr; %s', mw.text.nowiki(buffer), frame:preprocess(buffer))

return setmetatable({}, mt)
