“This book was a joy to read. It covered all sorts of techniques for debugging, including
‘defensive’ paradigms that will eliminate bugs in the first place. As coach of the USA
Programming Team, I find the most difficult thing to teach is debugging. This is the first
text I’ve even heard of that attacks the problem. It does a fine job. Please encourage these
guys to write more.” -Rob Kolstad
Perl Debugged provides the expertise and solutions developers require for coding better,
faster, and more reliably in Perl. Focusing on debugging, the most vexing aspect of
programming in Perl, this example-rich reference and how-to guide minimizes
development, troubleshooting, and maintenance time resulting in the creation of elegant
and error-free Perl code.
Designed for the novice to intermediate software developer, Perl Debugged will save the
programmer time and frustration in debugging Perl programs. Based on the authors’
extensive experience with the language, this book guides developers through the entire
programming process, tackling the benefits, plights, and pitfalls of Perl programming.
Beginning with a guided tour of the Perl documentation, the book progresses to
debugging, testing, and performance issues, and also devotes a chapter to CGI
programming in Perl. Throughout the book, the authors espouse defensible paradigms for
improving the accuracy and performance of Perl code. In addition, Perl Debugged
includes Scott and Wright’s “Perls of Wisdom” which summarize key ideas from each of
the chapters, and an appendix containing a comprehensive listing of Perl debugger
commands.
In this exceptional reference and debugging guide, the authors cover every aspect of
efficient Perl programming, including:
• CGI programming-special tips for debugging this type of Perl program
• How to develop the proper mindset for developing and programming effectively
in Perl
• Perl “gotchas”-how to understand them, work around them, and avoid them
• “Antibugging”-the authors’ rules of thumb on how to code defensively
• The Perl debugger -the authors’ guide to using this Perl built-in Common syntax
errors and how to track down their causes
• Semantical errors-why code may appear correct but the programs do not work
• How to improve the performance of resource-hungry programs
• Tips and advice for programmers moving to Perl from other language
environments
Focusing on the process of Perl programming and guidelines for identifying and
correcting mistakes, Perl Debugged helps the developer to write better Perl programs
immediately and become better programmers in general.
