save pp output to a string

Oliver

hi, folks -

how do I save the output from pp to a string for later use?

what I had hoped for is something like this:

x= [2, 3,4]
res = eval "pp x"

but that doesn't work.

thanks for help

Oliver

require 'pp'
x=[2,3,4]
string=""
PP.pp(x,string)
puts string
=> [2, 3, 4]

works for IO objects as well, or anything that supports <<.
