I put this in my .irbc

module IRB
  def self.result_format
     conf[:PROMPT][conf[:PROMPT_MODE]][:RETURN]
  end

  def self.result_format=(str)
     result_format.replace(str)
  end

  def self.show_results
     self.result_format = "=> %s\n"
  end

  def self.hide_results
     self.result_format = ''
  end
end

rick@frodo:~$ irb
irb(main):001:0> 1+2

irb(main):002:0> IRB.result_format

I'm not sure that I'm in love with my naming, but it does seem to
work.

One thing I just discovered.  I've got a few different versions of irb
installed.

If I try to run irb1.8.5 it doesn't seem to find ~/.irbc  If I
symlinked ~/.irb1.8.5rc to ~/.irbrc it seemed to work.

YMMV
