Ruby Question

Putting the results of pp (or anything outputted to console) into a string

We know

require 'pp'
a=["value1", "value2", "value3"]
pp a


pretty prints the array as an output to the console. How do I get that pretty output into a string (a string containing the newlines that makes things pretty, etc.)?

...purpose being to return that pretty string from a method.

Answer
a.pretty_inspect

pretty_inspect also comes along when you require 'pp' - See: http://ruby-doc.org/stdlib-2.1.0/libdoc/pp/rdoc/Kernel.html#method-i-pretty_inspect
