Written by three prominent members of the Perl community who each have several years of experience teaching Perl around the world, this latest edition has been updated to account for all the recent changes to the language up to Perl 5.8. Perl is the language for people who want to get work done. It started as a tool for UNIX system administrators who needed something powerful for small tasks. Since then, Perl has blossomed into a full-featured programming language used for web programming, database manipulation, XML processing, and system administration — on practically all platforms — while remaining the favorite tool for the small daily tasks it was designed for. You might start using Perl because you need it, but you'll continue to use it because you love it. Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the Llama to better match the pace and scope appropriate for readers getting started with Perl, while retaining the detailed discussion, thorough examples, and eclectic wit for which the Llama is famous. The book includes new exercises and solutions so you can practice what you've learned while it’s still fresh in your mind. Here are just some of the topics covered: data structures minimal matching threading data parsing references objects modules package implementation If you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will point to the Llama. With good reason. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.

One slogan of Perl is that it makes easy things easy and hard things possible. Intermediate Perl is about making the leap from the easy things to the hard ones. Originally released in 2003 as Learning Perl Objects, References, and Modules and revised and updated for Perl 5.8, this book offers a gentle but thorough introduction to intermediate programming in Perl. Written by the authors of the best-selling Learning Perl, it picks up where that book left off. Topics include: Packages and namespaces References and scoping Manipulating complex data structures Object-oriented programming Writing and using modules Testing Perl code Contributing to CPAN Following the successful format of Learning Perl, we designed each chapter in the book to be small enough to be read in just an hour or two, ending with a series of exercises to help you practice what you've learned. To use the book, you just need to be familiar with the material in Learning Perl and have ambition to go further. Perl is a different language to different people. It is a quick scripting tool for some, and a fully-featured object-oriented language for others. It is used for everything from performing quick global replacements on text files, to crunching huge, complex sets of scientific data that take weeks to process. Perl is what you make of it. But regardless of what you use Perl for, this book helps you do it more effectively, efficiently, and elegantly. Intermediate Perl is about learning to use Perl as a programming language, and not just a scripting language. This is the book that turns the Perl dabbler into the Perl programmer.

If you don't know any other programming languages, Chapters 2 through 7 will give you a solid introduction to the basics. If you already know another language, then skip Chapters 2 through 7 to see how Perl differs from other languages and start with Chapter 8, "References." This book follows a simple format. Each chapter contains a single topic-usually. First, you read about the topic and then you see examples that let you work directly with Perl to understand how the concepts can be applied to a program. At the end of each chapter is a summary, followed by review questions and exercises. This approach is designed to serve a broad range of readers from novice to advanced. If you've never programmed before, the learn-by-doing approach will help you move quickly and easily though this book. If you have programming experience, you'll find plenty of material to refine and enhance what you already know, and to give you a solid understanding of how Perl works.

Distilling many years of Perl experience--including an insiders look at Perl development (the authors are members of the Perl 6 core development team)--Perl 6 and Parrot Essentials, 2nd Edition is an unparalleled preview of major changes in the widely-anticipated Perl 6. This sneak peek of what’s coming in Perl includes succinct but thorough coverage of groundbreaking new developments in Parrot--the language-independent interpreter engine that will execute code written in the new Perl 6 language. Designed to be language independent, Parrot can be used to interpret other dynamic languages such as Python, Tcl, Ruby, and even Java. Perl 6 and Parrot Essentials also uncovers the most revolutionary change in the language itself--Apocalypse 12 on objects. The Apocalypse design documents (in the sense of “revealing”, not "end-of-the-world") explain significant changes in new Perl 6 features, numbered according to the chapters in O'Reilly’s landmark Camel book , Programming Perl. Apocalypse 12 is the result of cutting-edge research in object-oriented languages and is guaranteed to grab the attention of any serious Perl programmer. Perl 6 and Parrot Essentials also includes expanded coverage of Apocalypse 5 (regular expressions) and Apocalypse 6 (subroutines). Perl 6 and Parrot Essentials is the only book available to chart the course of the long but fruitful voyage of Perl 6. It reveals all the ingenious developments that will make Perl 6 more powerful and easier to use. Perl gurus and programmers alike will rely on this slim but essential book for both a clear view of the Perl horizon and to ensure they hit the ground running once this important new version of Perl is released.
