Latest revision as of 02:41, 29 September 2023

This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

This module depends on the following other modules:

Module:Arguments

This module supports Template:If empty.

Tracking/maintenance category

Category:Instances of Template:If empty missing arguments (0)

local p = {}

function p.main(frame)
	local args = require('Module:Arguments').getArgs(frame, {wrappers = 'Template:If empty', removeBlanks = false})

	for k,v in ipairs(args) do
		if v ~= '' then
			return v
		end
	end

end
