From the Back Cover
Write error-free programs from development to deployment!
Sidestep disaster with the tips, techniques, and expert insights contained in this one-of-a-kind resource. Debugging Perl shows you, step-by-step, how to fix buggy code and prevent errors from ever slipping into your programs. All the details you need to know are here'from avoiding syntax, logic, and variable problems as you program to troubleshooting with the Perl debugger, profiler, and compiler. Plus, you'll get design tips, little-known traps to watch out for, and a cross-referenced appENDix of error messages. When your Perl scripts must run cleanly on every system every time, turn to the real-world solutions offered in this unique handbook.
Learn to:
Optimize your code using the Perl debugger, profiler, and compiler
Troubleshoot variable expressions, regular expressions, compile-time statements, run-time outputs
Stamp out bugs caused by syntactical and logical mistakes
Implement subroutines, modules, and expressions to automatically detect potential problems
Trap errors using manual techniques, the Perl debuggers, and through the use of Perl's pragma system
Manage Perl memory usage and control system resources
Evaluate your scripts using test harnesses, code breaking, and system stress calculations

Debugging Perl is an ideal introduction to writing robust code in Perl. Tackling issues such as platform independant code and well defined Object Oriented code and coding styles all in Perl.
It's an excellent addition to your Perl library. Covering a great deal of ground on building robustness into your Perl applications, without straying from it target language and the idioms of Perl.
The name is a slight misnomer as the topic of Debugging with Perl's debugger is not the main feature here, surprisingly: what it does is teach the authors methods to reduce the occurance of bugs.
There are many books that cover coding standards and writing dependable code. Those I've seen cater for C code, but can be applied to any language if desired. This book provides good coding disciplines in Perl, that can be adopted easily by developers.
It could be argued that there is nothing new in this book that can't be found in the wealth of online documentation that the Perl community provides. Martin Brown has consolidated a wealth of Perl Documentation into one physical location, and picked a 'best path' through any disparities.
For me this book was an excellent read, filling gaps and introducing new uses for familiar concepts. It falls down as a "Real Perl Book" in as much that it is muted in it's references to the Perl Community and the wealth of libraries, reading material and tutorials it provides for free.

You need this before you meet the "real world"
29 Aug 2001
Format:Paperback
Very good. Author isn't only describing "how to debug Perl programs" but he's
mainly concerned in "how to write Perl programs that you won't need to debug" - this
sounds better, right ? A "hands-on" developer experience brought by someone who obviously
stepped on most of errors people may step and trying to warn you before you're doing
the same.
If "Programming Perl" is about "Perl", this book is about "real-world-Perl" and .. hey ..
those things aren't the same, as you should know (you *will* after reading the book).
Thank you, Martin !

It's about time...
21 Jan 2001
Format:Paperback
After a countless number of Perl books have been published, not much has been published like this book. The Learning Perl books are great, but learning the syntax isn't always the needed information to programmers. This book is different in that it focuses on some of the quirky odd things that you may run into programming. After designing in Perl for 3 years, I still run into times the code does not work the way I thought it would (maybe from thinking in C, Java, etc terms) and need a book of quirks instead a book of syntax. Finally, a book about how Perl behaves (or misbehaves). Great work. Long live Perl.
