The Classic Guide to Solving Real-World Problems with Perl—Now Fully Updated for Today’s Best Idioms!

 

For years, experienced programmers have relied on Effective Perl Programming to discover better ways to solve problems with Perl. Now, in this long-awaited second edition, three renowned Perl programmers bring together today’s best idioms, techniques, and examples: everything you need to write more powerful, fluent, expressive, and succinct code with Perl.

 

Nearly twice the size of the first edition, Effective Perl Programming, Second Edition, offers everything from rules of thumb to avoid common pitfalls to the latest wisdom for using Perl modules. You won’t just learn the right ways to use Perl: You’ll learn why these approaches work so well.

 

New coverage in this edition includes

 

  • Reorganized and expanded material spanning twelve years of Perl evolution
  • Eight new chapters on CPAN, databases, distributions, files and filehandles, production Perl, testing, Unicode, and warnings
  • Updates for Perl 5.12, the latest version of Perl
  • Systematically updated examples reflecting today’s best idioms

 

You’ll learn how to work with strings, numbers, lists, arrays, strictures, namespaces, regular expressions, subroutines, references, distributions, inline code, warnings, Perl::Tidy, data munging, Perl one-liners, and a whole lot more. Every technique is organized in the same Items format that helped make the first edition so convenient and popular.

Book News Annotation:

Presents programming solutions, techniques, pointers, rules of thumb, and pitfalls to avoid. Ten chapters include examples and cover basics, idiomatic Perl, regular expressions, subroutines, references, debugging, packages and modules, and object-oriented programming. Intended as a guidebook, not a manual, it is suitable for readers who have a basic understanding of Perl and a few months of practical experience.
Annotation c. Book News, Inc., Portland, OR (booknews.com)

Synopsis:

Powerful and flexible, Perl has established itself as a premier programming language, especially as a tool for World Wide Web development, text processing, and system administration. The language features full support for regular expressions, object-oriented modules, network programming, and process management. Perl is extensible and supports modular, cross-platform development.

In Effective Perl Programming, Perl experts Joseph Hall and Randal Schwartz share programming solutions, techniques, pointers, rules of thumb, and the pitfalls to avoid, enabling you to make the most of Perl's power and capabilities.

The authors will help you develop a knack for the right ways to do things. They show you how to solve problems with Perl and how to debug and improve your Perl programs. Offering examples, they help you learn good Perl style. Geared for programmers who have already acquired Perl basics, this book will extend your skill range, providing the tactics and deeper understanding you need to create Perl programs that are more elegant, effective, and succinct. This book also speaks to those who want to become more fluent, expressive, and individualistic Perl programmers.

To help you design and write real-world programs, Effective Perl Programming includes:

  • Perl basics
  • Idiomatic Perl
  • Regular expressions
  • Subroutines
  • References
  • Debugging
  • Usage of packages and modules
  • Object-oriented programming
  • Useful and interesting Perl miscellany

Numerous thought-provoking examples appear throughout the book, highlighting many of the subtleties that make Perl such a fascinating, fun, and powerful language to work with.
