Metaprogramming Ruby 2

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.

Updated: Programming Erlang, 2nd Ed.

This releases includes a few minor changes that were made to sync the book with the latest version of Erlang. The book was written before the specification of maps was finalized, so this edit corrects some small differences between the book and the Erlang release, in addition to correcting typos and other errata.
