(内容紹介より引用)

Ruby’s widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples.Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info.The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby

will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues.This guide will help youUnderstand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgradeDecide what belongs in a single Ruby classAvoid entangling objects that should be kept separateDefine flexible interfaces among objectsReduce programming overhead costs with duck typingSuccessfully apply inheritanceBuild objects via compositionDesign cost-effective testsSolve common problems associated with poorly designed Ruby code
