--[[
Emulate a print function for demonstration.
Note: we can use http://www.lua.org/cgi-bin/demo for non mediawiki libraries

Example:
for idx = 1, 5 do
	print( idx )
end

Example for UTF-8 encoded text:
s = "Hello World"
s = mw.ustring.sub(s, 1, 1)
-- compare with s = string.sub(s, 1, 1) or s = s:sub(1, 1)
print( s )

--]]

p = {}

p.loop = function(frame)
	local out = {}

	for idx = 1, 5 do
		table.insert(out, idx)
	end

	return table.concat(out, "<br>")
end

p.first = function(frame)
	local out = {}

	for idx, val in ipairs(frame.args) do
		s = mw.ustring.sub(val, 1, 1)
		out[#out + 1] = s -- this does the same job as table.insert
	end

	return table.concat(out, "<br>")
end
