Advanced Perl Programming, 2nd Edition By Simon Cozens Publisher: O'Reilly Pub Date: June 2005 ISBN: 0-596-00456-7 Pages: 304 Table of Contents | Index With a worldwide community of users and more than a million dedicated programmers, Perl has proven to be the most effective language for the latest trends in computing and business Every programmer must keep up with the latest tools and techniques This updated version of Advanced Perl Programming from O'Reilly gives you the essential knowledge of the modern Perl programmer Whatever your current level of Perl expertise, this book will help you push your skills to the next level and become a more accomplished programmer O'Reilly's most high-level Perl tutorial to date, Advanced Perl Programming, Second Edition teaches you all the complex techniques for production-ready Perl programs This completely updated guide clearly explains concepts such as introspection, overriding builtins, extending Perl's object-oriented model, and testing your code for greater stability Other topics include: Complex data structures Parsing Templating toolkits Working with natural language data Unicode Interaction with C and other languages In addition, this guide demystifies once complex topics like object-relational mapping and event-based development-arming you with everything you need to completely upgrade your skills Praise for the Second Edition: "Sometimes the biggest hurdle to problem solving isn't the subject itself but rather the sheer number of modules Perl provides Advanced Perl Programming walks you through Perl's TMTOWTDI ("There's More Than One Way To Do It") forest, explaining and comparing the best modules for each task so you can intelligently apply them in a variety of situations." Rocco Caputo, lead developer of POE "It has been said that sufficiently advanced Perl code is indistinguishable from magic This book of spells goes a long way to unlocking those secrets It has the power to transform the most humble programmer into a Perl wizard." Andy Wardley "The information here isn't theoretical It presents tools and techniques for solving real problems cleanly and elegantly." Curtis 'Ovid' Poe " Advanced Perl Programming collects hard-earned knowledge from some of the best programmers in the Perl community, and explains it in a way that even novices can apply immediately." chromatic, Editor of Perl.com Advanced Perl Programming, 2nd Edition By Simon Cozens Publisher: O'Reilly Pub Date: June 2005 ISBN: 0-596-00456-7 Pages: 304 Table of Contents | Index Copyright Preface Audience Contents Conventions Used in This Book Using Code Examples We'd Like to Hear from You Safari® Enabled Acknowledgments Chapter 1 Advanced Techniques Section 1.1 Introspection Section 1.2 Messing with the Class Model Section 1.3 Unexpected Code Section 1.4 Conclusion Chapter 2 Parsing Techniques Section 2.1 Parse::RecDescent Grammars Section 2.2 Parse::Yapp Section 2.3 Other Parsing Techniques Section 2.4 Conclusion Chapter 3 Templating Tools Section 3.1 Formats and Text::Autoformat Section 3.2 Text::Template Section 3.3 HTML::Template Section 3.4 HTML::Mason Section 3.5 Template Toolkit Section 3.6 AxKit Section 3.7 Conclusion Chapter 4 Objects, Databases, and Applications Section 4.1 Beyond Flat Files Section 4.2 Object Serialization Section 4.3 Object Databases Section 4.4 Database Abstraction Section 4.5 Practical Uses in Web Applications Section 4.6 Conclusion Chapter 5 Natural Language Tools Section 5.1 Perl and Natural Languages Section 5.2 Handling English Text Section 5.3 Modules for Parsing English Section 5.4 Categorization and Extraction Section 5.5 Conclusion Chapter 6 Perl and Unicode Section 6.1 Terminology Section 6.2 What Is Unicode?

Audience If you've read Learning Perl and Programming Perl and wonder where to go from there, this book is for you It'll help you climb to the next level of Perl wisdom If you've been programming in Perl for years, you'll still find numerous practical tools and techniques to help you solve your everyday problems YAML sessions, POE SGF (Smart Game Format) shutdown methods, Test::Class singleton method, applying to object rather than class skips, testing and Sleepycat Berkeley DB Smart Game Format (SGF) source filters spam, NLP for preventing SpamAssassin special variables $!
