Book Description

Adopted as the undisputed Perl bible soon after the first edition appeared in 1991, Programming Perl is still the go-to guide for this highly practical language. Perl began life as a super-fueled text processing utility, but quickly evolved into a general purpose programming language that’s helped hundreds of thousands of programmers, system administrators, and enthusiasts, like you, get your job done.

In this much-anticipated update to “the Camel,” three renowned Perl authors cover the language up to its current version, Perl 5.14, with a preview of features in the upcoming 5.16. In a world where Unicode is increasingly essential for text processing, Perl offers the best and least painful support of any major language, smoothly integrating Unicode everywhere—including in Perl’s most popular feature: regular expressions.

Important features covered by this update 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 Download Now »

Book Description

Perl 5 is a popular, powerful, and robust programming language. With countless satisfied developers, tens of thousands of freely available libraries, and continual improvements to the language and its ecosystem, modern Perl development can be easy, reliable, and fun. To take advantage of the full power of Perl 5–to become a true expert, capable of solving any problem put before you–you must understand the language. Modern Perl explains Perl 5 from theory to implementation, including Perl 5.12.

Perl 1.0 came out in 1987. In the decades since then, The language has gone from a simple tool for system administration somewhere between shell scripting and C programming (Perl 1) to a powerful, general purpose language steeped in a rich heritage (Perl 5) and a consistent, coherent, rethinking of programming intended to last for at least another 25 years (Perl 6).

Even so, most Perl 5 programs in the world take far too little advantage of the language. You can write Perl 5 programs as if they were Perl 4 programs (or Perl 3 or 2 or 1), but programs written to take advantage of everything amazing the worldwide Perl 5 community has invented, polished, and discovered are shorter, faster, more powerful, and easier to maintain than their alternatives.

Modern Perl is one way to describe how experienced and effective Perl 5 programmers work. They use language idioms. They take advantage of the CPAN. They’re recognizably Perlish, and they show good taste and craftsmanship and a full understanding of Perl. Download Now »
