Overview

This book picks up right where Learning Perl leaves off. With Intermediate Perl, you’ll graduate from short scripts to much larger programs, using features that make Perl a general-purpose language. This gentle but thorough guide introduces you to modules, complex data structures, and object-oriented programming.

Each chapter is small enough to be read in just an hour or two, ending with exercises to help you practice what you’ve learned. If you’re familiar with the material in Learning Perl and have the ambition to go further, Intermediate Perl will teach you most of the core Perl language concepts you need for writing robust programs on any platform.

Topics include:

  • Packages and namespaces
  • References and scoping, including regular expression references
  • Manipulating complex data structures
  • Object-oriented programming
  • Writing and using modules
  • Testing Perl code
  • Contributing to CPAN

Just like Learning Perl, material in this book closely follows the popular introductory Perl course the authors have taught since 1991. This second edition covers recent changes to the language up to version 5.14.

Described as the book that turns the Perl dabbler into the Perl programmer, this book is about making the leap from the easy things to the hard ones. It is written by the bestselling authors of "Learning Pearl" and offers a gentle but thorough introduction to intermediate programming in Perl.

Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
In Intermediate Perl, Perl legend Randal Schwartz, Tom Phoenix, and Brian Foy pick up where their classic Learning Perl left off. If you can write a basic Perl script, this book will help you write code that’s far more powerful and useful.

Up front, you’ll master some Perl idioms that’ll serve you well and learn to make the most of Perl’s huge library of modules. (Later on, there’s coverage of building your own modules.) Intermediate Perl presents extensive coverage of references, including nested element references, scoping, subroutine and filehandle references, even recursively defined data. You’ll learn to work with complex data structures; use namespaces without causing collisions; make more effective use of objects; even do some fairly serious testing.

Sure, there may be “more than one way to do it” in Perl. But when these authors tell you how, you know it’ll work. Bill Camarda, from the May 2006 Read Only

Meet the Author

Randal L. Schwartz is a two-decade veteran of the software industry. He is skilled in software design, system administration, security, technical writing, and training. Randal has coauthored the "must-have" standards: Programming Perl, Learning Perl, Learning Perl for Win32 Systems, and Effective Perl Learning, and is a regular columnist for WebTechniques, PerformanceComputing, SysAdmin, and Linux magazines.

He is also a frequent contributor to the Perl newsgroups, and has moderated comp.lang.perl.announce since its inception. His offbeat humor and technical mastery have reached legendary proportions worldwide (but he probably started some of those legends himself). Randal's desire to give back to the Perl community inspired him to help create and provide initial funding for The Perl Institute. He is also a founding board member of the Perl Mongers (perl.org), the worldwide Perl grassroots advocacy organization. Since 1985, Randal has owned and operated Stonehenge Consulting Services, Inc. Randal can be reached for comment at merlyn@stonehenge.com or (503) 777-0095, and welcomes questions on Perl and other related topics.

brian d foy has been an instructor for Stonehenge Consulting Services since 1998, a Perl user since he was a physics graduate student, and a die-hard Mac user since he first owned a computer. He founded the first Perl user group, the New York Perl Mongers, as well as the Perl advocacy nonprofit Perl Mongers, Inc., which helped form more than 200 Perl user groups across the globe. He maintains the perlfaq portions of the core Perl documentation, several modules on CPAN, and some stand-alone scripts. He's the publisher of The Perl Review, a magazine devoted to Perl, and is a frequent speaker at conferences including the Perl Conference, Perl University, MarcusEvans BioInformatics '02, and YAPC. His writings on Perl appear in The O'Reilly Network, The Perl Journal, Dr. Dobbs, and The Perl Review, on use.perl.org, and in several Perl usenet groups.

Tom Phoenix has been working in the field of education since 1982. After more than thirteen years of dissections, explosions, work with interesting animals, and high-voltage sparks during his work at a science museum, he started teaching Perl classes for Stonehenge Consulting Services, where he's worked since 1996. Since then, he has traveled to many interesting locations, so you might see him soon at a Perl Mongers' meeting. When he has time, he answers questions on Usenet's comp.lang.perl.misc and comp.lang.perl.moderated newsgroups, and contributes to the development and usefulness of Perl. Besides his work with Perl, Perl hackers, and related topics, Tom spends his time on amateur cryptography and speaking Esperanto. His home is in Portland, Oregon.

    Indispensable!

    If you've been using Perl for more than a year and you find yourself dealing with increasingly complex data structures, you probably need to get and read this book. It lays out tricks and techniques for storing, manipulating and using deeply layered hashes, arrays, anonymous entities and even references to subroutines. This book is clearly written, full of excellent and illuminating examples, peppered with exercises (and illustrations of possible answers to same) and even amusing now and then. There are a few errors to be found, but errata lists are available from the O'Reilly website so you can be edit them out yourself before you even read it. I review a chapter of this book weekly, and it has dramatically improved my productivity as a Perl programmer. As the title of this review says, this book is indispensable.
