Perl is a powerful interpreted programming language that has matured steadily since it first appeared in 1988. The first edition of this book, Programming Perl, hit the shelves in 1990, and was quickly adopted as the undisputed Bible of the language. Since then, Perl has grown with the times, and so has this book. Programming Perl provides a unique introduction to the Perl language and its culture, as you might expect only from its authors. This edition of the book has been expanded to cover version 5.14 of Perl with a preview of features in the upcoming 5.16. New topics include:
- New keywords and syntax
- I/O layers and encodings
- New backslash escapes
- Unicode 6.0
- Unicode grapheme clusters and properties
- Named captures in regexes
- Recursive and grammatical patterns
- Expanded coverage of CPAN
- Current best practices
A major strength of Programming Perl is the way subject areas are approached from several directions. This constant shift of viewpoint eliminates blind spots in the reader’s understanding and provides a pleasing echo of the way Perl itself can take many routes from here to there. Because the Perl community is both knowledgeable and active, the language covers much more ground here than in the previous edition. Even if you have both previous editions, you’ll want this latest version–if only for the new jokes. —Steve Patient, amazon.co.uk
Larry Wall wrote Perl and he wrote Programming Perl. Better yet, he writes amusingly and well–all of which comes across in this latest edition of the definitive guide to the language. First, it’s an introduction to the Perl language for those who are new to programming; also, it’s a guide for those who are coming from other languages; and, finally, it’s a Perl language reference.
Among Larry Wall’s other pursuits is being a linguist, and it’s perhaps for this reason that Perl is a peculiarly flexible language with many routes to achieving the same ends, as the authors ably demonstrate. It’s also extensible in several ways, designed to work with many other languages. Also, as it’s largely interpreted, programs written in Perl tend to run unmodified on a variety of platforms–although platform-specific Perl modules and programming practices are also discussed.
