How to split a string into only two parts, by the last occurrence of the split char?

Question

For example:

\"Angry Birds 2.4.1\".split(\" \", 2)
 => [\"Angry\", \"Birds 2.4.1\"] 

How can I split the string into: [\"Angry Bir

Answer 1

The rpartition solution makes a great sexy one-liner (I voted for it), but here's another technique if you want a one liner that's more flexible for solving more complex partitioning problems:

["Angry Birds 2.4.1".split(' ')[0..-2].join(' '), "Angry Birds 2.4.1".split(' ')[-1..-1].join(' ')]

By more flexible, I mean if there were more items being partitioned, you could just adjust the range of the sequence.
