Book Overview
Most Perl programmers know about the Perl debugger--the nifty little built-in utility that you can use to fully debug any programs that you write. Inside the interactive debugger environment, you're prompted for commands that let you examine your source code, set breakpoints, dump out function call stacks, change values of variables, and much more. It's so convenient that some programmers run it just to test out Perl constructs as they create a program. But although it's on their radar, not many Perl programmers take the time to master the debugger. That's where the Perl Debugger Pocket Reference comes in. This little book provides a quick and convenient path to mastery of the Perl debugger and its commands. Written by a core member of the Perl debugger development team, it's an ideal quick reference to debugger commands, as well as a detailed tutorial on how to get started. The Perl Debugger Pocket Reference provides complete coverage in a conveniently small package. Maybe you write code so clean you never have to look at it twice. Or perhaps you'd rather focus your energies on writing clean code, rather than learning about the debugger. But if you need to learn about the Perl debugger in a hurry, the Perl Debugger Pocket Reference is the book you'll want to have close by. And you can always keep a copy on hand to share with programmers who need it more than you do. O'Reilly's Pocket References have become a favorite among programmers everywhere. By providing a wealth of important details in a concise, well-organized format, these handy books deliver just what you need to complete the task at hand. When you've reached a sticking point in your work and need to get to a solution quickly, the new Perl Debugger Pocket Reference will get you back on the right track.

Cool Perl Debugger book for experienced programmers
Published by Thriftbooks.com User , 20 years ago
"Perl Debugger Pocket Reference" is a relativly short introduction into the command line Perl Debugger (perl -d option). You will find the following main chapters in this book:- Introductory chapters (partly meta chapters not about the debugger but about good programming)- Debugger Commands- Debugger Variables- Debugging Options- Debugger Internals, Quick reference, restWhen I bought this book I had hoped for a "...Pocket Guide" and not a "...Pocket Reference" (deeper coverage). I consider this not an extreme "...Pocket Reference" (like e.g. "Perl Pocket Reference") because this book contains examples for each of the commands and options that it describes. For me examples are the most important part in technical books.The language, the printing and the index (there is an alphabetic index) are of the usual high O'Reilly standard).I think that "Perl Debugger Pocket Reference" might be a bit heavy if you never used a command line debugger like gdb or xdb before. This book assumes that you already know what and why you want to do with the debugger, you will be explained WHO to do this with the debugger. PDPR is missing the process model when using a debugger. Personally I would have wished for even more examples and a bit more about when to use a certain feature of the debugger.For all those poor souls like me that still have to use Perl 5.5, you will not like this book because it explains the cool new features of the Perl 5.8 debugger (differences to Perl 5.6 covered as well) that are missing in Perl 5.5. I hope that I can convince my customer to upgrade to Perl 5.8 to be able to use cool new debugger (especially the w watchpoints will be great).I will keep this booklet next to my keyboard when I am Perl programming from now on to be able to lookup the Debugger functions that I will need. If you are a Perl programmer like me that does not produce flawless code, I really recommend this book. I will use it again right after finishing this review. Perl debugging will be more fun (for me) from now on.
