The Complete Guide to Writing Maintainable, Manageable, Pleasing, and Powerful Object-Oriented Applications
Object-oriented programming languages exist to help you create beautiful, straightforward applications that are easy to change and simple to extend. Unfortunately, the world is awash with object-oriented (OO) applications that are difficult to understand and expensive to change. Practical Object-Oriented Design, Second Edition, immerses you in an OO mindset and teaches you powerful, real-world, object-oriented design techniques with simple and practical examples.
Sandi Metz demonstrates 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 in the easy-to-understand Ruby programming language, all downloadable from the companion website, poodr.com. Fully updated for Ruby 2.5, this guide shows how to
- Decide what belongs in a single class
- Avoid entangling objects that should be kept separate
- Define flexible interfaces among objects
- Reduce programming overhead costs with duck typing
- Successfully apply inheritance
- Build objects via composition
Whatever your previous object-oriented experience, this concise guide will help you achieve the superior outcomes you’re looking for.

Paperback. Zustand: new. Paperback. Rubys widely admired simplicity 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, thoroughly explained via simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a proven set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She demonstrates 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. Fully updated for Ruby 2.X, this guide shows how to: Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code Whatever your previous Ruby experience, Practical Object-Oriented Design in Ruby, 2nd Edition will guide you to the superior outcomes youre looking for.
