Is there a built-in method or gem that can print a Ruby array in columns?

I have a large Ruby array that I would like to print in columns, just like the default output of Unix' 'ls' command (on OS X, at least). Is there a gem or built-in method that can do this? I am aware of the awesome_print gem. It's got some sexy output but it doesn't seem to offer columns.

Solution

  • I think hirb is more useful:

    require 'hirb'

Hirb.enable :output=>{"Array"=>{:class=>Hirb::Helpers::Table}}  #=> true

[[1,2], [2,3]]

| 0 | 1 |

| 1 | 2 |
| 2 | 3 |

2 rows in set

[[5,6,3,4]]
+---+---+---+---+
| 0 | 1 | 2 | 3 |
+---+---+---+---+
| 5 | 6 | 3 | 4 |

1 row in set
