prettyprint or pp questions

[Hal Fulton]

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...

PP.pp(obj, STDERR) # or change $>

str = ""; PP.pp(obj, str)

obj.pp(inspect)

require 'extensions/object'
str = obj.pp_s

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

STDERR.pp obj

STDERR.puts obj.pp_s

Cheers,

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".
