Usage

Module:Separated entries serves as a template front-end to mw.text.listToText. It takes any number of positional parameters and pieces them together with |{{SAFESUBST:#if:separator|separator=}}. |{{SAFESUBST:#if:conjunction|conjunction=}} can be optionally defined if a different separator is desired between the last and second last items. The starting positional parameter can be specified using |{{SAFESUBST:#if:start|start=}}. Leading and trailing whitespace is stripped; if the |{{SAFESUBST:#if:separator|separator=}} should contain spaces, use the HTML escape code  . Separated entries does not raise any errors by design.

-- 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 compressSparseArray = require('Module:TableTools').compressSparseArray
local p = {}

function p._main(args)
	local dataPlural = args.dataPlural
	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)
	local result = mw.text.listToText(values, separator, conjunction)
	if dataPlural and #values > 0 and (#separator > 0 or #conjunction > 0) then
		-- flag to [[Module:Detect singular]] whether this is a list with >1 element
		result = result..'<span style="display:none" data-plural="'..(#values > 1 and '1' or '0')..'"></span>'
	end
	return result
