简介
正如您在开车的时候，并不需要知道关于汽车的一切;当您开始使用Ruby进行编程的时候，也不需要立刻了解关于Ruby的一切。无论对于Ruby的新手还是老手，《学习Ruby》都是一本即学即用的实用教材。它提供了非常多的Ruby程序，并且解释了这些程序如何运行以及这样运行的原因。这些内容已经足以让您开始您的Ruby之旅。
由于网络开发框架Ruby on Rails的流行和大受欢迎，Ruby已经引起了很多Java和PHP开发人员的兴趣。但除了Rails之外，Ruby还有其他广泛的用途，而学习这些用法的最好方法就是动手尝试编写代码。在本书中，几乎每一页都可以找到代码例子。您可以仿照或者改写这些例子，生成您自己的代码。
本书包含以下主题：
* 介绍Ruby最重要的功能特性
* 示例说明如何使用条件语句以及如何使用Ruby字符串..
* 涵盖正则表达式
* 解释如何使用Ruby的操作符、有理数、算术表达式以及Math模块的函数
* 详细介绍Ruby数组和hash功能
* 讲解使用Ruby进行文件处理
* 对Ruby类和mixin模块的细节展开讨论，包括对面向对象编程的简要介绍
* 介绍XML处理、Tk工具包、RubyGems、反射机制（reflection）、RDoc、嵌入式Ruby、元编程（metaprogramming）、异常处理等内容
* 让您掌握Rails的基本知识，包括一个Rails的简单教程
每一章都有一组问题回顾，附录中有Ruby编程的名词对照表和书中用到的参考资料的出处。如果您想带着Ruby开车兜风，那么《学习Ruby》就是您的车钥匙。
