Where can I get a firmer grasp on ruby regex?
Post Body
I've been studying ruby for a while now and something that keeps coming up is the more intricate applications of regular expressions. Although I have a decent grasp on the basics the fundamentals surrounding parentheses, how to check a string from back to front using regex and other higher level operations using the pattern based searching system still evade my scope. Is there anywhere I can learn and practice regex operations in ruby?
