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), Read More ...

Book Description

This is a book for those of us who believed that we didn’t need to learn Perl, and now we know it is more ubiquitous than ever. Perl is extremely flexible and powerful, and it isn’t afraid of Web 2.0 or the cloud. Originally touted as the duct tape of the Internet, Perl has since evolved into a multipurpose, multiplatform language present absolutely everywhere: heavy-duty web applications, the cloud, systems administration, natural language processing, and financial engineering. Beginning Perl, Third Edition provides valuable insight into Perl’s role regarding all of these tasks and more.

Commencing with a comprehensive overview of language basics, you’ll learn all about important concepts such as Perl’s data types and control flow constructs. This material sets the stage for a discussion of more complex topics, such as writing custom functions, using regular expressions, and file input and output. Next, the book moves on to the advanced topics of object-oriented programming, Read More ...

Book Description

Many programmers code by instinct, relying on convenient habits or a “style” they picked up early on. They aren’t conscious of all the choices they make, like how they format their source, the names they use for variables, or the kinds of loops they use. They’re focused entirely on problems they’re solving, solutions they’re creating, and algorithms they’re implementing. So they write code in the way that seems natural, that happens intuitively, and that feels good.

But if you’re serious about your profession, intuition isn’t enough. Perl Best Practices author Damian Conway explains that rules, conventions, standards, and practices not only help programmers communicate and coordinate with one another, they also provide a reliable framework for thinking about problems, and a common language for expressing solutions. This is especially critical in Perl, because the language is designed to offer many ways to accomplish the same task, and consequently it supports many incompatible dialects.
