Graphing Perl's Regular Expressions

Unix Review > Shell Corner: Graphing Perl's Regular Expressions

Perl's regular expressions are cryptic, difficult to write, and impossible to understand. However, when graphed, the strings suddenly turn into something simple and fairly easy to understand. This month, Steve Oualline presents a Perl program that takes regular expressions and not only graphs their logic but their execution as well. It is all part of his book, Wicked Cool Perl Scripts.
