  • Preface

  • Modern Perl is one way to describe the way the world's most effective Perl programmers work. They use language idioms. They take advantage of the CPAN. They show good taste and craft to write powerful, maintainable, scalable, concise, and effective code. You can learn these skills too!
  • Modern Perl 은 세계에서 가장 효과적인 펄 프로그래머의 작업 방식을 설명하는 한가지 방법이다. 그들은 language idioms 를 사용한다. 그들은 CPAN 을 장점을 활용한다. 그들은 강력하고 유지보수, 확장성, 간결하고 효과적은 코드를 작성하는 좋은 맛과 기술을 보여준다. 당신도 이러한 기술을 배울 수 있다.
  • Perl first appeared in 1987 as a simple tool for system administration. Though it began by declaring and occupying a comfortable niche between shell scripting and C programming, it has become a powerful, general-purpose language family. Perl has a solid history of pragmatism and a bright future of polish and enhancement.

  • Over Perl's long history—especially the 19 years of Perl 5—our understanding of what makes great Perl programs has changed. While you can write productive programs which never take advantage of all the language has to offer, the global Perl community has invented, borrowed, enhanced, and polished ideas and made them available to anyone willing to learn them.

  • Running Modern Perl

  • The Modern::Perl module from the CPAN (The CPAN) asks Perl to warn of dubious constructs and typos and will enable new features introduced in modern Perl releases. Unless otherwise mentioned, code snippets always assume the basic skeleton of a program:
  • #!/usr/bin/env perl use Modern::Perl '2013'; use autodie;
  • ... which is equivalent to:
  • #!/usr/bin/env perl use 5.016; # implies "use strict;" use warnings; use autodie;
  • Some examples use testing functions such as ok(), like(), and is() (Testing). These programs follow the pattern:
  • #!/usr/bin/env perl use Modern::Perl; use Test::More; # example code here done_testing();
  • At the time of writing, the current stable Perl release family is Perl 5.18. If you're using an older version of Perl, you may not be able to run all of the examples in this book unmodified. The examples in this book work best with Perl 5.14.0 or newer, though we recommend at least Perl 5.16. While the term "Modern Perl" can refer to any version of Perl from 5.10.1, several features added in newer versions are essential to modern development.
  • perlbrew allows you to install and manage multiple versions of Perl. This allows you to switch between versions as well as to install Perl and CPAN modules in your home directory without affecting the system's version. If you've ever had to beg your system administrator for permission to install software, you know how much easier your life can be now.
