2025 RationalWiki 'Oregon Plan' Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff—we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $10, $20 or whatever you can today with PayPal Logo.png!

See documentation on wp:Module:Separated entries.


-- This module takes positional parameters as input and concatenates them with
-- an optional separator. The final separator (the "conjunction") can be
-- specified independently, enabling natural-language lists like
-- "foo, bar, baz and qux". The starting parameter can also be specified.

	local separator = args.separator
		-- Decode (convert to Unicode) HTML escape sequences, such as " " for space.
		and mw.text.decode(args.separator) or ''
	local conjunction = args.conjunction and mw.text.decode(args.conjunction) or separator
	-- Discard values before the starting parameter.
	local start = tonumber(args.start)
	if start then
		for i = 1, start - 1 do args[i] = nil end
	end
	-- Discard named parameters.
	local values = compressSparseArray(args)
