This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, multinationalization, and the new block declaration syntax, among other exciting new features.

A subprocess changes an environment vari- able, and this change is inherited by a process that it then starts. However, the change is not visible to the original parent. (This just goes to prove that parents never really know what their children are doing.) (查看原文)
When you design a class, you decide what internal state it has and also decide how that state is to appear on the outside (to users of your class). The internal state is held in instance variables. The external state is exposed through methods we’re calling attributes. And the other actions your class can perform are just regular methods. It really isn’t a crucially important distinction, but by calling the external state of an object its attributes, you’re helping clue people in to how they should view the class you’ve written.

开篇不谈镐头书 读尽诗书也枉然

挺详细的,但是后面的大半类库介绍就鸡肋了...你在计算机前不会用一个函数,你会ri一下还是把书翻开看那寥寥无几的介绍?

和1.8一样的差。。差差差！！meta program那块还算不错。推荐The Ruby Programming language!

如果能够用心看的话觉得对于初接触Ruby的新手是一本非常适合的书籍，第一部分详细介绍了Ruby的语法和优秀特性，适合初级入门。后面两部分更深入的讲解Ruby更高层次的运用和背后的原理，适合进阶阅读。第四部分就是供使用时查阅的常用库了。花了10天时间认真拜读了前三部分，受益匪浅，赞！

ruby的经典工具书，讲的很全面，需要不断反复看，遇到了以后会对于ruby的设计有新的理解，像duck type，lamda，GC等等。

初略浏览之后就当作词典放着，放着边上偶尔翻翻。

学习ruby必看的一本书，只是这本书洋洋撒撒上千页，需要花很多时间。。前后几乎用了半年才断断续续的看完。书里面简直保罗万象，关于Ruby的所有基本知识，而且例子都很简单明了，英语读起来也没有灰色难懂。从一个语言的角度，几乎讲到了一个高级语言应该有的所有feature。读完以后当作参考书是个不错的选择。
