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.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">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. </P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">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.
