Regular Expression Pocket Reference: Regular Expressions for Perl, Ruby, PHP, Python, C, Java and .NET (Pocket Reference (O'Reilly))

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 right 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. "Regular expressions arc a language used for parsing and manipulating text. They are often used to perform complex search-and-replace operations, and to validate that text data is well-formed." "Today, regular expressions are included in most programming languages, as well as in many scripting languages, editors, applications, databases, and command-line tools. This book aims to give quick access to the syntax and pattern-marching operations of the most popular of these languages so that you can apply your regular-expression knowledge in any environment."--Jacket
