Ruby: Split string at character, counting from the right side

Question

Short version -- How do I do Python rsplit() in ruby?

Longer version -- If I want to split a string into two parts (name, suffix) at the first \'.\' character, this

Answer 1

String#rpartition does just that:

name, match, suffix = name.rpartition('.')

It was introduced in Ruby 1.8.7, so if running an earlier version you can use require 'backports/1.8.7/string/rpartition' for that to work.
