Re: lua source as config file

This code is slow because it concats the file line by line.
See http://www.lua.org/pil/11.6.html

A better solution is to read it all at once:

function getconfig( file ) 
  local f = assert(io.open( file ))
  local ret = "return {" .. f:read"*a" .. "}"
  f:close()
  return ret
end

But I mean something with load (untested):

function loadconfig(file)
	local state=0
	local f = assert(io.open( file ))
	load(function()
		if state==0 then
			state=1
			return "return {"
		elseif state==1 then
			local s=f:read()
			if s==nil then state=2 s=}" end
			return s
		else
			return nil
		end
	end)
end
