具体描述

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.

想了解ruby元编程的话，先看法术手册。假如有不懂的话再返回到书有关这部分内容看，效果拔群。但也没人挡着你把书读完。不过整本书读起来也很爽，用mentor的语气写，也是另外一种文体嘛。期待第二版内容会更多。

作为一名JavaScript 开发者，在看本书的过程中每看到一个元编程技巧，都会忍不住将两种语言作一番比较和联想：在JavaScript 可以应用这种技巧吗？可以的话，这种技巧应用得广泛吗？某程度上JavaScript 比Ruby 更灵活，所以大部分技巧在JavaScript 都可以轻松实现。动态方法 ...

远超预期的惊喜在出行前的一天拿到这本书，翻了几页，感觉不错，心里很有些纠结。要出远门的原因，衣物和工作设备之外的东西要尽量精简。书籍方面反复挑拣，正在读和很想读的几本书，也都只好先放下，最后带上了这本新书和一本工作用书。在飞机上拿起这本书后，一边读，一...

此书不是基本入门书，但是想更好的应用ruby，在看完ruby基础后，应该看看此书，了解ruby真正的动态化威力。现在感觉做DSL，最方便的就是ruby了，因为有很多内置的方法就很适合元编程。前面两章，我看得这里的翻译，翻译的还不错，后面的就看网上的e文版，好在这本书的英文算...

这本书真的很有趣。通过一个编程老手带着一个菜鸟用元编程的技术重构代码，展示了元编程的实际应用场景。同时也不失时机的指出了一些坑。用会话的方式，来增加亲切感，这种组织方式，在编程书中并不少见。重点是作者的文采真的很好，显得很有灵性，下面摘抄一段（来自4.3.1 小...
