About the Book
This is a spinoff of a chapter from the Bastards Book of Ruby. Regular expressions are an essential and useful skill even outside of programming. They can serve not only as a handy tool for anyone whose work involves writing or data, but also act as a gateway into more interesting and complex kinds of programming. While you're waiting for me to finish this experiment in self-publishing, you can get a good start by reading the massive chapter on regular expressions in the BBoR
