Refactoring: Ruby Edition: Ruby Edition (Addison-Wesley Professional Ruby Series)

The Definitive Refactoring Guide, Fully Revamped for Ruby

 

With refactoring, programmers can transform even the most chaotic software into well-designed systems that are far easier to evolve and maintain. What€s more, they can do it one step at a time, through a series of simple, proven steps. Now, there€s an authoritative and extensively updated version of Martin Fowler€s classic refactoring book that utilizes Ruby examples and idioms throughout€“not code adapted from Java or any other environment.

 

The authors introduce a detailed catalog of more than 70 proven Ruby refactorings, with specific guidance on when to apply each of them, step-by-step instructions for using them, and example code illustrating how they work. Many of the authors€ refactorings use powerful Ruby-specific features, and all code samples are available for download.

 

Leveraging Fowler€s original concepts, the authors show how to perform refactoring in a controlled, efficient, incremental manner, so you methodically improve your code€s structure without introducing new bugs. Whatever your role in writing or maintaining Ruby code, this book will be an indispensable resource.
