Review

"A book about kick-starting your programming imagination . . . [it] will get you thinking about . . . creating practical solutions to your problems." -- About.com Guide to Perl, May 22, 2006

"Exemplifies the practical approach, highlighting utilities that make readers' computing and online lives easier." -- Library Journal Reviews, May 1, 2006

"Provides excellent and useful scripts to do the specific things the author intends them to be used for." -- O’Reilly.net, April 24, 2006

"This is not your typical Perl book . . . great for a Perl programmer who has a flair for unique issues." -- Free Software Magazine, April 20, 2006

From the Back Cover

You can do a lot of strange and wonderful things with the Perl language—if you know how. Many Perl programmers have been frustrated at one time or another because the system was missing some simple and obvious utility. Wicked Cool Perl Scripts is your guide to writing those utilities quickly and easily.

This book contains a wide variety of scripts including ones that make use of really cool Perl features (see script #1 Automatic Help Option) and Internet data mining (try script #18 Getting Stock Quotes or script #19 Comics Download).

It also contains games (like Teaching a Toddler, script #35), programs to make system administration easier (such as Mass File Renaming, script #21), and even a program to help someone hiking the Grand Canyon (script #42 Location Finder).

Even the most experienced programmer can benefit from script #46 the Regular Expression Grapher which shows you how a complex expression like /^.*(a|b|c).+$/ can be made into a simple, easily understood graph.

If you’re a Perl programmer who wants to learn the ins and outs as well as the hidden corners of the language, Wicked Cool Perl Scripts will show you simple and elegant hacks as well as some extreme examples of power programming. With Wicked Cool Perl Scripts in hand, you’ll be doing things you never even thought possible in Perl. You’ll be using the language to do real work, of course, but you’ll also be producing wickedly cool programs.

And when it comes down to it, I just didn't find many of the scripts all that interesting.

I don't recommend this book for beginning PERL programmers as there is not enough explanation to be useful for that purpose.

Unfortunately, this is a mistake, the correct code would be to use "return;" all on its own.

I couldn't resist the title, so I got this book. Unfortunately, I cannot reccommend it to people who want to learn to write better Perl, execpt as a source of examples of the mistakes you should avoid.

For example, in one of the earliest examples, the authors uses "return undef" in a situation where the return value of the routine is assigned to an array, to indicate the routine didn't find any of whatever it was looking for. Unfortunately, this is a mistake, the correct code would be to use "return;" all on its own. The correct solution produces an empty array or interim values; the mistake creates an array containing one element, 'undef'.

There are a number of similar mistakes which indicate the author is in over his head, writing things he doesn't understand; the editors know even less about the matter; and the code was never tested and verified for correctness.

If you want to learn Perl, get "Learning Perl"; If you want to improve your Perl, get "Intermediate Perl.

I don't usually feel strong enough to write reviews however don't buy this book unless you want to spend hours debugging someone elses code just for the fun of it. I could have written my own in less time that it took me to fix the errors found in the code. In addition you would expect the downloadable code to work and they don't either. They are not even the same code examples found in the book. Unless you want to pay for the ideas and what modules to use this book is a waste of money.

I'm going to be grumpy about this.

I have nothing good to say about this book. I don't have anything bad to say (except maybe that I dislike titles like this), but nothing grabbed me, nothing excited me.

Maybe that's because the kinds of examples presented are just what Perl is best at doing - the author demonstrates that a properly stocked toolbox can indeed be used to build a birdhouse, repair a sticking door, hang a picture. Yaaaawnn..

If you know nothing whatsoever about Perl, I suppose this might be fun. But why would you read it if you knew nothing? I think that's probably the basic flaw here: it's not a "Learn Perl" book, and it doesn't explore the more esoteric areas. The subtitle says "Useful Perl Scripts that solve difficult problems", but there are no difficult problems here, just building birdhouses, hanging pictures, and so on.

Just not my cup of tea, I guess.

Format: Paperback
This books gives good examples of different perl scripts for many situations. What I really like about the book was the outline for each script. It gave an intro to the situation and what the script would do, the script itself, an explanation on how the script works, and then tips for modifying the script to fit you needs. A neat book just to poke around in. The only downside was that the majority of scripts were web oriented, because I use perl to administer my network and was looking for something more along that line.

Format: Paperback
This is a great book for learning by example, particularly as a follow-on to something like Learning Perl to get you started. It provides a number of useful scripts (even though some of them duplicate functionality of common system utilities), with explanations of how and why they work, and even notes on how you might alter the code to suit your own purposes. If you're a relatively new programmer that already has the basics of Perl in mind, but find yourself at loose ends wondering what to do next to help cement what you know and start learning more, this book may be exactly what you need. It's also useful for figuring out some of the basic principles of translating code between Perl and another language, thanks to the source code explanations.

The scripts themselves, however, are not exactly what I would call "wicked cool". The title is an obvious marketing conceit, designed to make the book seem more enticing. Most of the scripts, in fact, are surprisingly mundane -- but that doesn't mean they aren't useful. You may actually find yourself using some of them, with minor alterations, in your day-to-day life. Just don't expect to be wowed by the scripts themselves.

Format: Paperback
This book wants to be a recipe book. But in my opinion it doesn't do it's job very well. There are too many simple examples inside (which take a lot of space) and can be found in similar form on-line. Also, the author doesn't do a very well job at explaining things the right way and it seems the examples aren't that well thought through (both the choice of examples and their presentation).

The recipes explained in the book are not nearly as good as those in ie. Perl Cookbook, and don't seem to be that usable either. This book looks more like a collection of school assignments with solutions than practical examples needed by a developer. It may be interesting for someone who wants to learn Perl, but then it may also be too hard for beginners to comprehend the code inside the book (the explanations are not that elaborate).

The list of recipes might look interesting at first glance, but if you go into depth with this book, you soon notice that it simply isn't worth it.
