I don't know, but the ri docs sure are sparse for ruby 1.8.6 (2007-03-13):

  $ ri scanf
  More than one method matched your request. You can refine
  your search by asking for information on one of:

       IO#block_scanf, IO#scanf, Kernel#scanf, String#block_scanf,
       String#scanf

  $ ri Kernel.scanf
  ----------------------------------------------------------- Kernel#scanf
       scanf(fs,&b)
  ------------------------------------------------------------------------
       (no description...)

But the original project examples at

  http://www.rubyhacker.com/code/scanf/

might get you going...
