Custom module to apply either some wiki markup or a template to each item in a comma delimited list. Look at Template:Class for examples.


local p = {}

function split(instr,sep)
   local sep, fields = sep or ":", {}
   local pattern = string.format("([^%s]+)", sep)
   string.gsub(instr, pattern, function(c) fields[#fields+1] = c end)
   return fields
end

function trim(s)
   return (s:gsub("^%s*(.-)%s*$", "%1"))
end

function p.apply(frame)
	local list = frame.args[1]
	local pattern = frame.args[2]
	local result = {}
	local sep = ','
	
	local newSep = frame.args[3] or ''
	
	for key,entry in pairs(split(list,sep)) do
		result[#result+1] = string.gsub(pattern, '%%pattern%%', trim(entry))
	end
	
    return table.concat(result,newSep) 
end

function p.applyTemplate(frame)
	local list = frame.args[1]
	local template = frame.args[2]
	local substArg = frame.args[3]
	
	
	local newSep = frame.args[4] or ''
	
	local result = {}
	local sep = ','
	
	for key,entry in pairs(split(list,sep)) do
		local argTable = {}
		argTable[substArg] = entry
		result[#result+1] = frame:expandTemplate{title = template, args = argTable}
	end
	
    return table.concat(result,newSep) 
end

return p
