Win a Free Copy of Regex Cookbook 2nd Edition
Update: This contest is now finished. See the list of winners.
I'm excited to announce the release of Regular Expressions Cookbook 2nd Edition, which I wrote together with regex superguru Jan Goyvaerts. It has actually been available as an ebook for a couple weeks on oreilly.com, but as of now, it is also in stock on amazon.com.
To promote this release, O'Reilly Media is giving away free copies to 15 people who comment on this post on or before September 7th! To get a free copy, you must read the details at the end of this post. But first, some FAQs about the second edition:
Wait…this is a cookbook?
The book tackles hundreds of real-world regular expression tasks in a problem, solution, discussion format. There's also a detailed regular expression tutorial included, in the same format. Check out Jeff Atwood's and Ben Nadel's reviews of the first edition, which have more details about this.
Update: Rob Friesel Jr. posted an awesome, detailed review of the second edition.
The first edition was a bestseller, and is now available in eight languages. It briefly held Amazon's #1 spot for computer books upon its release in mid 2009, and the ebook version was O'Reilly's top seller of 2010.
What has changed with this new edition?
The second edition adds more content, and updates existing chapters. There are innumerable improvements, including the most noticeable addition of a new chapter written by Jan, titled Source Code and Log Files, and various new recipes interspersed with four of the other chapters.
There are 101 new pages in the second edition, and that's after shortening and removing some content from the first edition. There were 125 recipes in the first edition, upped to 146 in the second. Note that many of the book's recipes provide solutions and in-depth discussions for more than one problem. Tons of changes, ranging from minor copyedits and errata corrections to major revisions and the addition of significant new content, were made throughout the existing content. Everything was brought up to date with the latest standards, tools, and programming language versions. In particular, updates to Java and Perl since the first edition brought very significant regular expression changes. Plus, we've covered some advanced regular expression features that already existed the last time around, but didn't make it into the first edition.
The first edition was already groundbreaking for the depth of its explanations and its equal coverage of all regexes in eight programming languages (C#, Java, JavaScript, Perl, PHP, Python, Ruby, and VB.NET). The second edition significantly improves upon this by providing even more details about the many peculiarities and differences of the APIs, syntax, and behavior of these regex flavors and programming languages. The second edition also adds coverage of XRegExp when it provides a better solution than native JavaScript. IMO, the second edition is easily the most comprehensive source of information about the use of modern regexes across multiple programming languages—far more detailed than anything else in print or online.
What will interest long-term fans the most?
Even though there are lots of important changes throughout the book, the new recipes and the updated coverage for the latest programming languages are probably the main reasons for owners of the first edition to upgrade. The fully-new recipes cover creating a regex-based parser, validating password complexity, adding thousands separators to numbers, matching various kinds of numbers, decoding XML entities, and everything in the new Source Code and Log Files chapter. The coverage of XRegExp is also completely new in the second edition.
What will cause readers to trip over themselves in their haste to buy a copy?
If you read though the book, you'll learn about a lot of things—much more than just regular expressions. You'll almost certainly learn something new about Unicode, phone numbers, and XML, as just a few examples. You'll learn that the eighth floor of the Saks Fifth Avenue store in New York City has its own ZIP code, which also happens to be the only ZIP code that includes letters. You'll learn that the Chicago Manual of Style and Merriam-Webster's Biographical Dictionary disagree on the correct alphabetical listing of the name Charles de Gaulle (my girlfriend and I are in opposing camps). Jan and I put a ton of research into the book, and we pay attention to details. I think that shines through.
Oh yeah, and along the way, you'll also become a Master Chef of regular expressions, able to slice and dice text with the best of them. But not everyone will want to actually read through the book. Some readers will prefer to take advantage of the cookbook format and read only the parts that solve their immediate problems. That's fine, too.
Many developers complain that they're continually relearning regular expressions, going back to the reference documents every time they need to write a new regex. The problem/solution approach of Regular Expressions Cookbook means you learn by doing, and we think that helps the details stick with you more securely than with the other books and websites out there.
Many regex novices turn to Google to get prewritten regexes that solve their problems. Unfortunately, if you're not already fluent in regex, you won't realize that 90% of the regexes out there have some kind of problem, be it returning false positives or negatives, performing inefficiently (or maybe even crashing your server when fed malicious data), being more complicated than necessary, not being portable, or what have you. When you use the regexes in Regular Expressions Cookbook, not only do you get detailed coverage of all the related issues (which helps you customize the solution, if necessary), you also get the peace of mind that you're using proven solutions by real subject-matter experts.
So how do I enter to win a free copy?
Simply comment on this blog post on or before 11:59 PM EDT on September 7th, and you'll be in the running. I wish I could leave the contest open a bit longer, but I'll be moving to California to work for a little Internet startup. You'll need to use your actual first and last name and email address with your comment. Names are published, but email addresses are not. Each person commenting has only one chance to win, regardless of how many comments they post. If you don't know what to write in your comment, just mention whether you'd prefer a print or ebook copy.
Shortly after this contest ends, I'll randomly choose 15 winners and contact them by email. If you prefer a printed copy, I'll be asking for your address and, if you're outside of the U.S., your phone number. O'Reilly will pay for shipping to anywhere in the world. Good luck!
Coauthor Jan Goyvaerts has written up his own summary of the changes in What's New in The Second Edition of Regular Expressions Cookbook.

Comment by jack simmonds on 2 September 2012:
This sounds like a phenomenal time saver for those not already expert at creating regex. I know I go looking for ready made solutions when I have to get something done. I enjoy figuring them out, but it’s nice to have proven code when you’re adding features to a site.
I’d be happy to get either the print or e-book versions. The easiest would be the e-book.

Anyway, I will be very glad to get any version of it. And in addition I’m going to buy one in translation to my language when it will be printed.
Thanks in advance!

Comment by Ray Daly on 2 September 2012:
I have the ebook of the previous Verizon and store it my Dropbox. When coding RegEx I’ll often write it myself and then search the Cookbook to see if I missed anything. Email is a perfect example. The authors had done the research and I had better validation for my form.
I look forward to getting the new ebook edition even if I don’t win it here.

Would love an ebook copy of the book.
Comment by Scott Thorne on 2 September 2012:
I “live in” MS Office apps most of every workday (sound familiar to any of you?), it’s the business thing. Anyway, when trying to work smarter, I am often looking in RegEx reference trying to improve search/replace and VBA scripts. I doubt I’m the only person like this, doing most regex like tasks when banging on MS Office Word (aargh). That should get some content allocation as well.
I prefer ebooks. I use a Kindle, so mobi is good, but I find myself referring to the PDFs on the PC more often.
Comment by Pete Lamonica on 2 September 2012:
Cool beans! I’d love an ebook!

Comment by Remy Bach on 2 September 2012:
RegEx has literally changed the way I code and I only know the beginnings of what it can do! I’d love to get either version and get a better knowledge on the subject!
Comment by Kyle Davis on 2 September 2012:
Wow. I could use a copy!
Comment by Ilan on 2 September 2012:

Comment by Henk Scholten on 2 September 2012:

Comment by wbeeftink on 5 September 2012:
I’m really looking forward to the 2nd edition of your book. I’ve always found regular expressions to be especially intriguing because of their concisiveness (compared to common string parsing). Your and Jan’s website have been a great source for learning and I’m really interested in the book to delve deeper and have a reference handy.

This book and the accompanying website are great resources to learn about the regular expression. It can also be helpful for the students of Automata theory. They can have hands-on experience rather than paper work or on guess. I recommend this book and website for the students and practitioners.

Comment by Stafleu Buitendag on 7 September 2012:
Good morning
Strangely enough, although regex is such a versatile and useful tool, I don’t actually get to use it as much as I would wish during my day to day work life. If I could be lucky enough to own a copy of Regex Cookbook, I’d like to own a printed copy, to always have it handy (I find that ebooks tend to find a folder on my pc, and generally settle there…I am still to acquire a decent ebook reader).
Kind regards
Stafleu

I need an ebook copy.
Comment by Jeff Davis on 31 January 2013:
I’ve used (and continue to use) regular expressions in Perl, JavaScript, PowerShell and ColdFusion. It amazes me that I can still find “good stuff” like the examples in Steven’s “Regular Expressions Cookbook 2nd Edition”, but it shouldn’t. This is a must-have for the technical bookshelf…
