Turning off individual bundled outputs

So, the title there. What I'm trying to do is create a massive UU-Matter factory in Tekkit Lite that automatically generates the entire chain of desired components; i.e. it spits out UU-Matter, crafts it into Iron Ore, and then smelts that into ingots. So far, so good- I can make the actual factory.

My plan was then to make an 'overseer' program for each 'section' (ores, building materials, etc.) so I can turn off each section as needed. But how do I get it so the program can turn off, say, the black in a red-black-white bundle without turning off the OTHERS?

You can use the following code as an API (shout if you need further explanation)

Spoiler

local outputColor, outputSide
local inited = false

local init = function(side, color)
	-- color here is the original color value (eg. white + red + black =
	-- colors.white + colors.red + colors.black = 1 + 16384 + 32768 = 49153)
	outputSide = side
	outputColor = color
	inited = true
end

local toggleOutput = function(color) -- color here is the color you want to turn off or on
	if (inited) then
		outputColor = bit.bxor(outputColor, color)
		rs.setBundledOutput(outputSide, outputColor)
	end
end

local function turnOff( ... )
  local off = 0
  local old = rs.getBundledInput( 'right' )
  for _, c in pairs(arg) do
    off = off + c
  end
  rs.setBundledOutput( 'right', colors.subtract( old, off ) )
end

then you can call it in these ways (and more)

turnOff(colors.red)
turnOff(colors.red, colors.blue, colors.black)
turnOff(colors.yellow, colors.red, colors.lime, colors.black, colors.brown)

basically you can enter any number of colours you wish.

If either of those functions don't work for you, one or both of the first two functions in my Useful Snippets post may interest you.

I'll be trying these tonight- my sever ate the world while I was out. Will update, and thanks for all the advice :)/>

You guys nailed it- thanks ;)/>
