标题：精通Perl
内容提要
本书是0’Reilly具有里程碑意义的Perl教科书系列的第三本，该系列包括《LearningPerl》(最为畅销的一本介绍Perl基础语法的书，简体中文版由东南大学出版社出版)、《Intermediate Perl》(一本Perl程序员必备的指导如何创建可重用的Perl软件的书)和《精通Perl》。《精通Perl》由浅入深地剖析了Perl特殊模块的工作机理、细致详尽地阐述了惯用的Perl 编程思想和技术，这些知识必能协助你在开发Perl程序时游刃有余，达成所需。
本书解释了该如何：使用高级正则表达式，包括全局匹配、前后查询匹配、可读的正则表达式以及对正则表达式的调试；使用安全可靠的编程技术，避免常见的编程问题；剖析Perl运行时数据并作基准测试，继而有针对性地进行性能优化；重新组织Perl代码，使其更具自我表达力，增强可读性；查看Perl如何实现对包变量的跟踪维护，你可以用类似的技巧玩出更多有用的花样来；动态定义子程序，从容化解普通过程式编程带来的劣势；临时修改或调整相关的模块，在不修改源代码的情况下修复代码存在的问题；在不触及代码的情况下，让用户自行对程序进行配置；侦测Perl没有报告的那些错误并向用户汇报；应用Log4Perl模块，从Perl程序的运行日志获取有价值的信息；存储相关数据以便后续再次运行该程序或其他程序时可以访问该数据，以及如何通过网络发送数据以Perl模块的形式编写应用程序，以便使用现成的测试工具并轻松发布。
本书将带你一路揭示这些问题的答案，让你从容地成为能够发现并解决疑难杂症的专家。
