Dig under the surface and explore Ruby’s most advanced feature: a collection of techniques and tricks known as metaprogramming. In this book, you’ll learn metaprogramming as an essential component of Ruby and discover the deep, non-obvious details of the language. Once you understand the tenets of Ruby, including the object model, scopes, and singleton classes, you’re on your way to applying metaprogramming both in your daily work assignments and in your fun, after-hours projects.

Metaprogramming Ruby, Second Edition makes mastering the language enjoyable. The book is packed with:

Pragmatic examples of metaprogramming in action, many of which come straight from real-life gems such as Rails.

Programming challenges that let you experiment and play with some of the most out-there metaprogramming concepts.

Metaprogramming “spells”—33 practical recipes and idioms that you can study and apply right now, to write code that is sure to impress.

This completely revised new edition covers the new features in Ruby 2.0 and 2.1, and contains code from the latest Ruby libraries, including Rails 4. Most examples are new, “from the wild,” with more recent libraries. And the book reflects current ideas of when and how much metaprogramming you should use.

Whether you’re a Ruby apprentice on the path to mastering the language or a Ruby wiz in search of new tips, this book is for you.

作者风格：自娱自乐，尤其喜欢描写新人和导师之间的对白动作，什么“导师掏出上衣口袋的纸巾擦擦汗”，”丢下了键盘，跑到会议室“之类的，感觉像小说。不过，从章节划分，细节讨论来说，非常不错。用了不少典型库的代码段来说明如此设计的目的，加上对一些陷阱的提问，面面...
