Does not support newlines from anything printed (like love.errorhandler)

[NicePotato-MS]

it just goes offscreen

I have fixed the function myself, and opened a pull request #9

I changed the add_to_output from

function add_to_output(...)
    local arg = {...}
    local narg = select("#", ...)

    for i = 1, narg do
        arg[i] = tostring(arg[i])
    end

    msg = parse.color(table.concat(arg, " "))
    table.insert(output_buffer, msg)
end

to

function splitString(...)
    local lines = {}
    for _, str in ipairs({...}) do
      for line in str:gmatch("[^\r\n]+") do
        table.insert(lines, line)
      end
    end
    return lines
end  

function add_to_output(...)
    for k, arg in ipairs(splitString(...)) do
        msg = parse.color(table.concat({arg}, " "))
        table.insert(output_buffer, msg)
    end
end

Updated to support some edge cases

function splitString(...)
	local lines = {}
	for _, arg in ipairs({...}) do
	  	if arg == nil then
			-- Handle nil values
			table.insert(lines, "<nil>")
	 	 elseif type(arg) ~= "string" and type(arg) ~= "boolean" then
			-- Handle non-string and non-boolean values
			table.insert(lines, tostring(arg))
	  	else
			local str = tostring(arg)
		if type(arg) == "boolean" then
		  -- Convert boolean values to lowercase strings
		  str = str:lower()
		end
			for line in str:gmatch("[^\r\n]*\r?\n") do
		  	-- Handle empty lines
		  	if line ~= "\r\n" and line ~= "\n" then
					table.insert(lines, line)
		  		end
			end
	  	end
	end
	return lines
end

You may actually want to check that, I'm not sure if that's completely correct

[NicePotato-MS]

Yea, that actually completely breaks everything, adjust the first one
