Over the years, Perl has grown from an elegant scripting tool into a mature and full-featured language for application development, boasting object-oriented programming, a flexible threading model, built-in support for Unicode, and a thriving community. Available on almost every platform, and offering a comprehensive library of modules, there is no task too big or small for Perl to tackle.

Pro Perl helps you master the key features and complexities of this powerful language. Aimed at intermediate and advanced developers alike, the material assumes some general knowledge of programming concepts but not necessarily prior Perl experience. However, given the expansive coverage of core language topics, Pro Perl also serves as a valuable guide to seasoned Perl programmers seeking to push their proficiency to the next level.

Using a depth-first approach to aid learning of advanced concepts, you’re provided with detailed examinations of many key topics, including regular expressions, networking, modules and packages, object-oriented development, and much more. Pro Perl seeks to provide developers with not only the answers to their programming questions, but also advanced ideas and related concepts that expand the developer's understanding of Perl as a language.

This edition of Pro Perl offers updated and expanded content, and improved organization by combining material from previous editions of Professional Perl Programming and Professional Perl Development.

    bulking up

    Remember when Perl was a nice little scripting language? One that you could master in a few days. The success of it led to the incorporation of many new features. Most important of these being perhaps the ability to write object oriented code. The sum total of these features causes a blurring of a difference from 'full' languages like C++ or Java. While it is still possible to program using much of early Perl, this book's aim is to educate you as to the new material. Yes, Perl's scope is now impressive. What with a comprehensive regexp, bidirectional pipes, Unicode and more. How much of this to take in from the book is up to you. Thankfully, the chapters seem mostly independent of each other. So at this level, you have random access, which means you don't have to read all of the book. Each chapter, however, has a strong narrative sense of progress. You should read a desired chapter end to end. A little irony here. Remember claims by some early proponents of Perl that you could skip the complexity of C++'s STL, for example? Or, more recently, to avoid the bulking up of the class packages in standard Java. Perl now has the same symptoms of success.
