Subject: Re: My .irbrc for console/irb

I've been using this guy for code that prints copious output to the
terminal.  I'm sure it could be improved a bit, but I've found it
useful.

  def less
    require 'stringio'
    $stdout, sout = StringIO.new, $stdout
    yield
    $stdout, str_io = sout, $stdout
     IO.popen('less', 'w') do |f|
       f.write str_io.string
       f.flush
       f.close_write
     end
  end

I tend to use that in conjunction with yaml dumps to look at complex
data structures, rather than pp, but that would work just as well.

  def yp(*data)
    require 'yaml'
    puts YAML::dump(*data)
  end

Give them a whirl like so:

  $ irb
  less { yp IRB.conf }
