4.0 out of 5 stars A review of "Regular Expression Pocket Reference", July 12, 2005

By	G. Roush (Des Moines, IA USA) - See all my reviews (REAL NAME)

One of the most difficult things when working with regular expressoins -- at least for me -- is dealing with different implementations (i.e., Perl, Java, Python, PHP, UNIX tools, etc.) The basics of regexes and pattern matching don't vary all that much, but each implementation is just different enough that the smae line of code can yield different results. If you work with more than one of these implementations, keeping track of differences in metacharacters and metasequences can be nearly impossible. This is especially true when -- as is the case with me -- you deal with regexes somewhat intermittently.

This is one of the main reasons why the "Regular Expression Pocket Reference"
was written and this is why I keep it close at hand. This book will not really teach you how to use regexes, nor will it tell you how to use, say, Perl. If, however, you use Perl and you know how to use regexes but just can't remember whether you can disallow backtracking for text matched by a subpattern, then this book will save you quite a bit of time and effort.

If you're wondering what it means to "disallow backtracking for text matched by a subpattern," or when you would want to use it, buy "Mastering Regular Expressions" or a similar title. The "Regular Expression Pocket Reference" is designed to be a quick reference tool, and it serves this purpose very well. I would recommend it especially for those who work with regular expressions intermittently or who work with several different implementations.

2.0 out of 5 stars Too many implementations covered, December 15, 2003

By	"mark_seattle" (Kirkland, WA United States) - See all my reviews

I love this series of books (the C#, C++ and STL pocket refs are my favorite), but the Regular Expression pocket ref tries to cover too many implementations. You only get about 10 pages for each language so, unless you use multiple implementations (e.g. C#/.NET, Perl, JavaScript, etc), this just isn't good value for money. I returned my copy and printed out a quick reference from one of the many Internet programming sites.

4.0 out of 5 stars Great reference, but not a tutorial, November 20, 2003

By	David C. Veeneman (Lincolnshire, IL USA) - See all my reviews (REAL NAME)

The editorial blurb on this book suggests that it can be used as a tutorial by those new to regular expressions. That's not the case. This book is strictly a reference, albeit a very good one. I bought O'Reilly's "Mastering Regular Expressions" to learn the area, and I use this book as a quick reference. It serves that purpose very well.
