block_compressor

-- Compression program.
-- Fills 3x3 grid with items and crafts.
-- Intended for crafting of things like compressed cobblestone, redstone blocks, etc.

-- Algorithm:
-- While able to pull stacks from above inventory:
 while turtle.suckUp() do
    turtle.select(16)
    -- Distribute stack across 3x3 grid.
        stackSize = turtle.getItemCount(16)
        distSize = (stackSize-(stackSize % 9)) / 9
        if stackSize >= 9 then
            turtle.transferTo(1, distSize)
            turtle.transferTo(2, distSize)
            turtle.transferTo(3, distSize)
            turtle.transferTo(5, distSize)
            turtle.transferTo(6, distSize)
            turtle.transferTo(7, distSize)
            turtle.transferTo(9, distSize)
            turtle.transferTo(10, distSize)
            turtle.transferTo(11, distSize)
        end
        turtle.select(16)
        turtle.drop()
    turtle.craft()
    -- Place contents of slot 16 into inventory in front of turtle.
    turtle.drop()
