This handy little book offers programmers a complete overview of the syntax and semantics of regular expressions that are at the heart of every text-processing application. Ideal as a quick reference, Regular Expression Pocket Reference covers the regular expression APIs for Perl 5.8, Ruby (including some upcoming 1.9 features), Java, PHP, .NET and C , Python, vi, JavaScript, and the PCRE regular expression libraries. This concise and easy-to-use reference puts a very powerful tool for manipulating text and data left at your fingertips. Composed of a mixture of symbols and text, regular expressions can be an outlet for creativity, for brilliant programming, and for the elegant solution. Regular Expression Pocket Reference offers an introduction to regular expressions, pattern matching, metacharacters, modes and constructs, and then provides separate sections for each of the language APIs, with complete regex listings including: Supported metacharacters for each language API

Regular expression classes and interfaces for Ruby, Java, .NET, and C

Regular expression operators for Perl 5.8

Regular expression module objects and functions for Python

Pattern-matching functions for PHP and the vi editor

Pattern-matching methods and objects for JavaScript

Unicode Support for each of the languages

With plenty of examples and other resources, Regular Expression Pocket Reference summarizes the complex rules for performing this critical text-processing function, and presents this often-confusing topic in a friendly and well-organized format. This guide makes an ideal on-the-job companion. Review:

if you know reg exps and switch languages a lot... "Regular Expression - Pocket Reference" is just as high in quality as it's big brother ("Mastering Regular Expressions.") The book begins with a very brief review of regular expression concepts and patterns. For each language/tool, the book includes tables to reference the metacharacters, a reference for the API/syntax/library and four examples. A few of the languages have additional examples tailored specifically to that language. The languages/tools included are: Perl, Java, .NET, PHP, Python, Ruby, JavaScript, PCRE, Apache Web Server, vi and awk/sed/egrep. If you use a number of these, the book is a concise reference. If you only use one, you would be better served by printing out the relevant reference charts from the website of your language of choice. If you are learning about regular expressions or only going to buy one regular expressions book, I recommend the "Mastering Regular Expressions." If you are knowledgeable about regular expressions and just need a review or reference, this book does the job nicely.

Review:

Easy to use due to excellent organiztion This book is the best reference for regular expressions. The second edition came out in July 2007 and has several updates over the previous version. The reason for the books ease-of-use lies in the organization. The chapters represent one language each. For each language, listings of the meta-characters and examples are shown. Depending on the language being displayed, there are other subjects covered such as unicode support, object orientation, and different topics unique to the language. The primary parsing engine is listed at the beggining of the chapters with the examples arranged at the ends of the chapters. I generally need to look up expression for JavaScript and [...]. Both of these are covered plus perl, java, php, python, ruby, pcre, apache, vi and shells. I just bookmark the 2 areas I need and I can lookup the expression listing in a few seconds. Review:

Excellent concise reference for regular expressions This is a handy little guide for common regular expression fundamentals and odds and ends. The intro chapter does a nice job of giving you the regex elevator speech and hits all the important fundamentals: different engines, metacharacters, and general pattern rules. There's also a regex "Cookbook" section; however, that bit is only two pages and the "recipes" there are so rudimentary that they're nearly useless and would have been better left to a different book. The remaining chapters hit regex support in major languages, Apache, shells, and Vi and Vim editors. These sections are very well done and give you great guidance to regex implementations on that platform, plus give you guidance on the APIs you'll need for working with regexes. Languages covered include Perl 5.8, Java 1.5/1.6, .NET framework with examples in C , PHP, Python, Ruby, Python and JavaScript. The Perl Compatible Regular Expression library (PCRE) is also covered. Each chapter is concise, well-written and hits the major things you'll need to refresh your memory on from time to time. Overall it's a very well done book.
