There was few bugs in it before, but now you can use most of printf syntax with % operator:

1.9.3-p194 :025 > " %-20s %05d" % ['hello', 12]
 => " hello                00012" 

Of course you can use precalculated width too:

1.9.3-p194 :030 > "%-#{width}s %05x" % ['hello', 12]
  => "hello          0000c"
