Product Description

From Amazon

Effective Perl Programming is a gem of a Perl book. Its author, Joseph Hall, is a well-known Perl instructor and frequent poster on the seminal comp.lang.perl.misc newsgroup. The book's technical editor is none other than Randal Schwartz, noted Net personality and enigmatic author of Learning Perl.

Hall has distilled his years of Perl experience into a book for Perl programmers that is both fluid and fun to read. It's somewhat like reading the Perl FAQ; even when you think you know everything, there's so much you don't know.

Effective Perl Programming has a clear layout: the text is easy on the eyes and the mono-spaced font makes a clear distinction between backticks and single quotes. Hall uses his PEGS (Perl Graphical Structures) notation to show the difference between Perl's different types of data structures and how everything ties together.

Packed with great examples and code snippets, this book is an excellent source of tips and tricks to make your Perl programs faster and easier to read. You'll also find a strong section on using the Perl debugger to improve your Perl programming skills. In yet another section, Hall walks the reader through the creation of a complete XS module that can boost the performance of array shuffling eight-fold. All in all, this is a great book for programmers who want to move beyond plain, verbose Perl toward a more succinct and powerful coding style. --Jake Bond

From Library Journal

Perl is an amazingly powerful language that is especially useful for web work with Common Gateway Interfaces. This is not a book for beginners but for people who have some experience being confused by Perl. Hall discusses namespace, regular expressions, references, packages, and object-oriented programming. The goal of this book is not to write clear, legible, slightly verbose Perl code but "toward something more succinct and individualistic."

Perl starts out as a world unto its own, full of strange symbols, it is shrouded in a world of mystery and obfusaction (or not :) ).
Admit it, part of the charm of perl is writing some obscure JAPH one-liner, being able to get 'shebang' jokes, and knowing what the heck $$->a->razzle()->dazzle might actually accomplish.
But how to get there? You've probably read the Llama and the Camel. You've probably got some bigh honkin scripts out there doing some heavy lifting. Heck, you may have cobbled a RegEx together that unravels the Necronmicon. All this and yet....
Odds are you came from a C-ish or similar background and you realize that you're still writing C or Java, but in Perl.
This book is the Emerillian kick to the next level. Realizing that languages, Perl especially, have idioms, best practices, standards, Hall acquanints you with them.
Just as children are baffled by "a fork in the road" you may find handy idioms like my ($b) = ($a=~m,(^\w+?),) something you have to look up, or memorize -- but later you'll realize that you *needed that* phrase in order to round out your vocabulary (just like a 'fork in tho road').
Hall also makes good suggestions that will help make your code tighter, helping your banish overuse of globals (impossible for someone else to maintain). He teaches you to document and follow standards.
this book was critical in my development form perl-plateaud and stymied, to perl-proficient.
Thanks Hall!

The day I got this book, I turned to page 1 and started reading. Two hours later, I had made it only to page 80. Why? Because this book is DENSE and FULL of tips and tricks that will expand the horizons of the intermediate programmer. I spent a lot of time studying the numerous examples in order to soak up all the information that was being presented.
I've been programming with Perl since 1992 and teach it at a community college. And yet with every turn of the page, I learned something new. Examples:
Making regular expressions more efficient
Using map() and grep()
How to call a subroutine from inside a string
Great stuff! The techniques I've learned from this book have been incorporated into my new Perl scripts and they are shorter and faster than ever before.
I can't lavish enough praise on this book. Authors Joseph Hall and Randal Schwartz should be commended. If you have been using Perl for some time and want to hone your skills, get this book now.

This book had the most profound and dramatic impact on my understanding of Perl. The sooner you read this book the better! (The only minor drawback I see is that OO part is somewhat sketchy but even then it still contains quite valuable insights.)
The thing I like most about this book is the density of useful information. In this respect no other book I've read can overcome Mr. Joseph Hall's achievement. Not even close. "Effective Perl Programming" makes you think about Perl in ways you never thought before. When I read a paragraph about sorting techniques and especially Schwartzian transform (p.49-50) it was difficult to fall asleep. Amazing and inspiring stuff!
Programming Perl is not as easy as it seems. This book gives you most tricks of the trade. (The rest one can find in "Perl Cookbook" which I also like very much.) Heartedly recommended. Hope to see other books by Mr. Hall in the nearest future. Not necessarily about Perl!

Format: Paperback
Effective Perl Programming is a concise, well written guide that is packed with useful Perl tips. The book is a series of "Items" (in the same style as Effective C++) that are each a tip about how to use Perl. Each tip is accompanied by a detailed description that discusses the pros and cons or each tip and several examples. The tips are then arranged into sections such as "Regular Expressions" and "Object Oriented Programming". In a relatively small book the authors manage to present an enormous amount of helpful information.
This book is a worthwhile purchase if you are a new or intermediate Perl developer. The tips presented here will really help improve your code. However, if you have been working with Perl for a while then this book isn't worth the money. There might be a tip or two that you don't know, but chances are you know most of what is presented.

Format: Paperback
I've been using Perl casually for a few years now, but when I first got this book six months ago, I sort of skimmed through it and didn't find anything too interesting. But when I started doing a few Perl projects, I kept thinking, "Hey, didn't that book say something about a better way to do this?" So I'd look it up, and an elegant solution to my problem would be there. It's not that I couldn't have done it without the tip, because as all Perl programers know, "There's More Than One Way To Do It", but it taught me a cleaner way than I would have done otherwise.
Most tips are no longer than a few pages, and they are neatly organized by topic ("Regular Expressions", "Subroutines", etc.) in the index. Highly recommended for the semi-experienced Perl programmer who is looking to polish their programming skills.
