Prettyprint or pp questions

ruby-talk
1

There are three things I would like to do but I am not
sure how:

1. Redirect the output to another IO -- something like

        STDERR.pp obj

2. Retrieve the text without printing it (analogous to #inspect):

        str = obj.pretty # or whatever

3. Add pp functionality to the Date class. This doesn't work:

         class Date
           def pretty_print
             inspect
           end
         end

Thanks for assistance...

1. Redirect the output to another IO -- something like
        STDERR.pp obj

  PP.pp(obj, STDERR) # or change $>

2. Retrieve the text without printing it (analogous to #inspect):
        str = obj.pretty # or whatever

   str = ""; PP.pp(obj, str)

3. Add pp functionality to the Date class. This doesn't work:

         class Date
           def pretty_print(obj)
             inspect

                obj.pp(inspect)

           end
         end

  require 'extensions/object'
  str = obj.pp_s

        STDERR.pp obj

  STDERR.puts obj.pp_s

P.S. It seems to me that all the questions you're asking should be
more elegantly solved by the 'pp' library. That it, it should all
"just work".
