本书指导你从一个Perl爱好者变成一个Perl程序员。《Intermediate Perl》将教您如何把Perl作为编程语言来使用，而不仅只是作为一种脚本语言。

Perl是一种灵活多变、功能强大的编程语言，可以应用在从系统管理到网络编程再到数据库操作等很多方面。人们常说Perl让容易的事情变简单，让困难的事情变得可行。《Intermediate Perl》正是关于如何将技能从处理简单任务跃升到胜任困难任务的书籍。

本书提供对Perl中级编程优雅而仔细的介绍。由畅销书《学习Perl》的作者所著，本书提供了《学习Perl》没有涵盖的内容。

主题包括：
* 包和命名空间
* 引用和作用域
* 操作复杂数据结构
* 面向对象编程
* 编写和使用模块
* 测试Perl代码
* 为CPAN贡献代码

参照《学习Perl》的成功编排格式，本书的每一章都短小到可以在一到两个小时内读完，并在结束时提供一系列练习题帮助您实践刚刚学到的知识。使用本书，您只需熟悉《学习Perl》的内容并有更进一步学习的决心。

对于不同的人而言Perl是一种不同的语言。对于某些人而言，它只是快速编写脚本的工具，但对于另外的人来说，它就是一种功能完整的面向对象语言。Perl被应用在各种任务当中，从对文本文件进行快速全局替换，到计算需要数星期才能完成处理的海量复杂科学数据。您的使用决定Perl的面貌。但不论您将Perl应用在什么方面，本书都将帮助您让应用更加有效、高效和优雅。

《Intermediate Perl》是为了把Perl作为一种编程语言来学习，而不仅是为了写脚本而著。这本书把Perl爱好者变为Perl程序员。

“这是本多么闪耀夺目的Perl书籍啊……这本书为那些渴望提高技能或者提升职业生涯的Perl程序员填补了空白。更为重要的是，看这本书有一种向大师学习的感觉。”

Randal L. Schwartz是软件工业界经历了两个时代的老战士。他精通软件设计、系统管理、安全、技术写作和培训。Randal与他人共同编著了许多已成为事实标准的“必备”书：《Programming Perl》、《Learning Perl》、《Learning Perl for Win32 Systems》和《Effective Perl Programming》，他还是杂志《WebTechniques》、《PerformanceComputing》、《SysAdmin》和《Linux》的专栏作家。他也是Perl新闻组的一位多产作者，并从comp.lang.perl.announce开始时就是它的管理员。他不落俗套的幽默和大师风范的技术在全世界范围内已经堪称传奇（不过可能他自己本身早就开始了这个传奇）。Randal回馈Perl社区的愿望促使他帮助成立了The Perl Institute，并提供了初始资金。他还是Perl Mongers（perl.org）创建理事会的成员，这是一个世界范围的Perl基层推广组织。从1985年起，Randal拥有并经营Stonehenge Consulting Services公司。Randal的联络方式是merlyn@stonehenge.com或（503）777-0095，欢迎广大读者与他共同探讨Perl的一些问题以及其他相关主题。








Randal L. Schwartz是一个电子零售商和企业家，靠软件设计、技术协作、系统管理、安全咨询和影像产品谋生。他以他的丰富的、幽默的和偶尔不正确的内容而闻名网络新闻组——特别是在comp.lang.perl上他的“Just another perl hacker”的签名。
Randal在Tektronix、ServioLogic和Sequent工作的7年磨练了许多技艺。在过去的 5年里，他在他的家乡奥勒冈州波特兰市已经开办并经营了Stonehenge Consulting Services
公司。

Randal L. Schwartz is a renowned expert on the Perl programming language. In
addition to writing Learning Perl and the first two editions of Programming Perl, he
has been the Perl columnist for UNIX Review, Web Techniques, Sys Admin, and
Linux Magazine. He has contributed to a dozen Perl books and over 200 magazine
articles. Randal runs a Perl training and consulting company(Stonehenge Consulting

Tom Phoenix自1982年起一直从事教育工作。他曾经在一个科学博物馆工作过13年以上，工作内容包括解剖、爆炸，还有可爱的动物、高压火花等。之后，从1996年起，他开始在Stonehenge Consulting Services讲授Perl课程。从那以后，他到过很多有趣的地方，因此也许你不久就会在一个Perl Mongers大会上见到他。一有时间，他就会在comp.lang.perl.misc和comp.lang.perl.moderated新闻组上回答问题，并致力于Perl的开发和利用。除了从事与Perl相关的工作、与Perl高手沟通及相关工作以外，Tom业余时间还从事密码学研究并练习世界语。他的家在俄勒冈的波特兰。
Tom Phoenix has been working in the field of education since 1982. After more than
13 years of dissections, explosions, work with interesting animals, and high-voltage
sparks during his work at a science museum, he started teaching Perl for Stonehenge
Consulting Services, where he’s worked since 1996. As it is traditional for Perl people
to have at least three other unlikely interests, Tom enjoys amateur cryptography,
Esperanto, and Squeak (Smalltalk). According to rumor, he has never turned down
an opportunityto playa game of Zendo. He lives in Portland, Oregon, with his wife
and cats.
 
 
The animal on the cover of Intermediate Perl is an alpaca (Lama pacos). The alpaca is
a member of the South American camelid family, which is closely related to the more
familiar Asian and African camels. South American camelids also include the llama,
the vicuna, and the guanaco. The alpaca is smaller (36 inches at the withers) than a
llama but larger than its other relations. Ninety-nine percent of the world’s approximately
three million alpacas are found in Peru, Bolivia, and Chile.
The evolution of the wild vicuna into the domestic alpaca began between six and
seven thousand years ago. The specialized breeding of alpacas for fiber production
wasn’t developed until around 500 B.C. The Incas developed the alpaca into the two
distinct fleece types, the Huacaya (pronounced wa-kai-ya) and the less common Suri.
The main difference between the two types of alpacas is the fiber they produce. The
Huacaya fleece has crimp or wave; the Suri fleece is silky and lustrous and has no
crimp. Alpacas are prized for their fleece, which is as soft as cashmere and warmer,
lighter, and stronger than wool. Alpaca fleece comes in more colors than that of any other fiber-producing animal (approximately22 basic colors with manyvariations
and blends).
The lifespan of the alpaca is about 20 years. Gestation is 11.5 months, producing one
offspring, or cria, every14 to 15 months. The alpaca is a modified ruminant, not
onlyeating less grass than most other animals but converting it to energyveryefficiently.
Unlike true ruminants, they have three compartments in their stomach, not
four, and can thus survive in areas unsuitable to other domesticated animals. Alpacas
are gentle and don’t bite or butt. Even if theydid, without incisors, horns, hoofs, or
claws, they would do little damage.
