Effective Perl Programming
is a gem of a Perl book. Its author, Joseph Hall, is a well-known Perl instructor and frequent poster on the seminal comp.lang.perl.misc newsgroup. The book's technical editor is none other than Randal Schwartz, noted Net personality, enigmatic author of Learning Perl
, and contributor to Programming Perl
Hall has distilled his years of Perl experience into a book for Perl programmers that is both fluid and fun to read. It's somewhat like reading the Perl FAQ; even when you think you know everything, there's so much you don't know.
Effective Perl Programming has a clear layout: the text is easy on the eyes and the monospaced font makes a clear distinction between backticks and single quotes. Hall uses his PEGS (PErl Graphical Structures) notation to show the difference between Perl's different types of data structures and how everything ties together.
Packed with great examples and code snippets, this book is an excellent source of tips and tricks to make your Perl programs faster and easier to read. You'll also find a strong section on using the Perl debugger to improve your Perl programming skills. In yet another section, Hall walks the reader through the creation of a complete XS module that can boost the performance of array shuffling eight-fold. All in all, this is a great book for programmers who want to move beyond plain, verbose Perl toward a more succinct and powerful coding style.
Perl experts Joseph Hall and Randal Schwartz share sixty concise lessons, focusing on programming techniques, pointers, rules of thumb, and the pitfalls to avoid, enabling students to make the most of Perl's power and capabilities. Through their advice, they help students develop a knack for the right ways to do things. They show how to solve problems with Perl, and how to debug and improve Perl programs. Through examples, they help you learn good Perl style. Geared for students who have already acquired Perl basics, the book will extend students' skill range, giving them the tactics and deeper understanding they need to create Perl programs that are more elegant, effective, and succinct. The book also speaks to those who want to become more fluent, expressive, and individualistic Perl programmers. The author maintains a substantial companion website at http://www.effectiveperl.com.
