.NET, Java, JavaScript, PCRE, Perl, Python, and Ruby aren’t just back-cover buzzwords. These are the seven regular expression flavors covered by this book. We cover all seven flavors equally. We’ve particularly taken care to point out all the inconsistencies that we could find between those regular expression flavors.
The programming chapter (Chapter 3) has code listings in C#, Java, JavaScript, PHP, Perl, Python, Ruby, and VB.NET. Again, every recipe has solutions and explanations for all eight languages. While this makes the chapter somewhat repetitive, you can easily skip discussions on languages you aren’t interested in without missing anything you should know about your language of choice.
