The First Hands-On, Practical, All-Ruby Refactoring Workbook!


Refactoring–the art of improving the designof existing code–has taken the world by storm. So has Ruby. Now, forthe first time, there’s a refactoring workbook designed from the groundup for the dynamic Ruby language.

Refactoring in Ruby givesyou all the realistic, hands-on practice you need to refactor Ruby codequickly and effectively. You’ll discover how to recognize “codesmells,” which signal opportunities for improvement, and then perfectyour program’s design one small, safe step at a time.

The book shows you when and how to refactorwith both legacy code and during new test-driven development, and walksyou through real-world refactoring in detail. The workbook concludeswith several applications designed to help practice refactoring inrealistic domains, plus a handy code review checklist you’ll refer toagain and again. Along the way, you’ll learn powerful lessons aboutdesigning higher quality Ruby software–lessons that will enable you toexperience the joy of writing consistently great code.

Refactoring in Ruby will help you
Recognize why poor code design occurs, so you can prevent it from occurring in your own code
