Master intermediate to advanced techniques of the Perl programming language starting with a focus on regular expressions and some of their advanced features. This book then covers other pro-level features, including formatted output, file handling, and more. Additionally, you'll learn and explore the most useful built-in variables, pragmas, and modules available in the Perl language. Furthermore, you'll work with geometry managers and get a thorough treatment of graphical user interface development using Perl/TK and widgets. Lastly, you’ll cover debugging techniques. Pro Perl Programming is a professional-level reference guide on Perl and includes important aspects of it that you need as a professional programmer. What You Will Learn Program regular expressions including atoms, smartmatch operators, and more Use advanced features such as HiRes Time, slurp() functions, Critic, Tidy and many more functions Handle advanced formatted output such as printf and sprintf Explore useful built-in variables, including status variables, separator variables, and the signal handle variable Explore and use Perl's built-in modules, including the Pragma modules Work with Perl/TK and its widgets-like geometry managers, frames, labels, buttons, check buttons, radio buttons, scrollbars, scales, entries, and menus Who This Book Is For Those with at least some prior experience with Perl programming or have read Beginning Perl Programming by William Rothwell.

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.

The 2001 classic - available in eBook formats for the first time 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.

Perl was originally written by Larry Wall while he was working at NASA’s Jet Propulsion Labs. Larry is an Internet legend, known not just for Perl, but as the author of the UNIX utilities rn, one of the original Usenet newsreaders, and patch, a tremendously useful tool that takes a list of differences between two files and allows you to turn one into the other. The term patch used for this activity is now widespread. Perl started life as a “glue” language for Larry and his officemates, allowing one to “stick” different tools together by converting between their various data formats. It pulled together the best features of several languages: the powerful regular expressions from sed (the Unix stream editor), the patte- scanning language awk, and a few other languages and utilities. The syntax was further made up out of C, Pascal, Basic, Unix shell languages, English, and maybe a few other elements along the way. While Perl started its life as glue, it is now more often likened to another handy multiuse tool: duct tape. A common statement heard in cyberspace is that Perl is the duct tape that holds the Internet together.
