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

    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.
