Content Description

作为最有影响力的编程语言之一，Perl被广泛用在Web开发、数据处理和系统管理中。无论是Perl新手，还是想要加强自己实战技能的Perl程序员，《Perl入门经典》都提供了处理日常情况所需的各种技术。凭借十多年的Perl经验，作者Curtis“Ovid”Poe一开始先简单回顾了Perl的基础知识，然后以此为出发点，举例说明了Perl在工作场所中的各种真实用法。此外，书中还包含了一些动手练习、宝贵建议和实用例子，作者把所有这些内容冶于一炉，打造了一本不可或缺的经典之作。
主要内容
·讲解如何使用Perl的内置函数处理数据；
·展示使用Perl处理Unicode的做法；
·详细介绍控制流及引用、文件和目录的处理等基础知识；
·分别用一章的篇幅详述Perl的面向对象功能和Moose；
·提供全面的自动化测试介绍；
·讲述Catalyst、DBIx：：Class和其他一些广受欢迎的模块的用法；
·由知名开发者Chromatic担任技术编辑，他也是一位多产的作家，是多本Perl图书的作者。

Author Description

Curtis "Ovid" Poe，从2000年开始专注于Perl的开发，他是一位作家，也是一位演讲嘉宾，定期在欧洲和美国各处举行的会议上发表演说。他所编写的测试框架目前正随同Perl语言一起发行。

Comments

“这不是大家日常所见的那种入门书，Ovid不仅提供了关于Perl基础知识和最佳实践的精彩讲解，而且还介绍了一些先进的Perl技术和模块，而这些正是Perl的真正强大之处。这就像是系上了蝙蝠侠的配件腰带，你拥有了创造出真正令人惊叹的东西所需的一切。如朵Perl是一条鲨鱼，那么本书就是在教你如何使用激光发射器来装备它。”
——Paul Fenwick，Perl Training Australia

Introduction

“找份工作吧，嬉皮士！”
拒绝使用这句话作为本书的副标题是很遗憾的事情，但也很明智。不过，它传达出了关于本书我很看重的两件事，那就是：在学习所需的技能时做到赢取工作和享受乐趣两不误，好吧，是该在学习如何编程的同时适度地享受一些乐趣了。尽管许多书都没有直言这样的意图，但我还是在此先把它给挑明了吧：这是一本与赚钱有关的书。信息技术（Information Technology，IT）工作者的需求量很大，甚至是在当前经济不景气的时候也是如此，本书这样说凭借的不仅是我13年的Perl编程语言经验，还有就“野生状态的Perl”这一主题所做的一些调查。这就是为什么你将会在书中发现一个令人吃惊的决定：本书把关注的重点放在Perl的5.8和5.10版本上，它们已不再是官方支持的版本，但却是大多数的公司仍在使用的版本。幸运的是，Perr5Porters（也被称作P5P）努力保持着向后兼容，因此本书中的代码依然能够运行在最新版本的Perl上。作为这一重点关注的结果，在完成本书的学习后，你将拥有在接受许多Perl工作时必须具备的技能。最初我设想这是一本以开发工作技能为目标的Perl语言书，当时我住在俄勒冈州的波特兰市；后来，我搬到了伦敦，并做了一些跟写作本书有关的调查，但没有起到什么作用；再后来，我搬到了阿姆斯特丹，开始与Wrox合作撰写本书；现在，我住在巴黎，并在此完成本书的写作。所有这些城市呈现出来的共同迹象是，Perl打开了工作的大门。在许多其他优秀的动态语言，比如说PHP、Python和Ruby正在为同一块馅饼争斗时，一些Perl开发者却转向了其他语言，离开了那些需要开发者使用Perl语言来维护代码和构建新系统的公司，Perl开发者的需求量居高不下，本书的出现就是为了满足这一需要。
为了免得你认为Perl的作用就是维护遗留代码，我向你保证，许多公司，包括大型的和小型的，仍都在转向Perl，把它作为编程语言的首选。该语言功能强大、切实可靠，Perl综合典藏网（Comprehensive Perl Archive Network，CPAN）仍是面向单门语言的最大开源代码集。许多时候你会发现，不一定需要编写新的代码来解决某个棘手问题，你可以求助于CPAN，在上面找出他人已写好的这类代码。
