How to get Ruby objects printed out in their 'natural' form

Kenneth McDonald

For debugging purposes, I'd like to be able to do something like

print [1,2,3]

and have "[1,2,3]" printed to the screen, not 123. How do I go about
this. I've experimented with to_s and puts, and not found anything
obvious.

Thanks,
Ken

C:\Documents and Settings\chen73>irb
irb(main):001:0> a=[1,2,3]
=> [1, 2, 3]
irb(main):002:0> p a
[1, 2, 3]
=> nil
irb(main):003:0>

Each object has method inspect and it does the trick. The irb in fact
prints the result's inspect to show it to you.

["a",:b,3].inspect #=> "[\"a\", :b, 3]"
