More beautiful, indented, pretty-printing

Array.inspect returns its output in a flat line:

aoa = [ [1,2,3], [4,5,6] ]
puts aoa.inspect # => [[1, 2, 3], [4, 5, 6]]

Is there an easy way to get an indented output instead? The exact format (e.g., whether there is a line break after the first [) is not important to me. I just would like to have it more readable.

Compare Perl:

  DB<2> print Dumper([[1,2,3],[4,5,6]])
$VAR1 = [
          [
            1,
            2,
            3
          ],
          [
            4,
            5,
            6
          ]
        ];

The solution should support hashes as well and handle other things gracefully.

Solution

  • You might want to try the AwesomePrint gem which would return the following by default (the actual output is colored) and is customizable:

    aoa = [ [1,2,3], [4,5,6] ]
#=> [
#     [0] [
#       [0] 1,
#       [1] 2,
#       [2] 3
#     ],
#     [1] [
#       [0] 4,
#       [1] 5,
#       [2] 6
#     ]
#   ]
