The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications

 

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 you

  • Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade
  • 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

Synopsis:

Years after the initial release of Ruby on Rails, the chickens are coming home to roost. Suddenly, anyone could write a web application — and it seems like everyone did. The web is now awash in Ruby applications that were easy to write but are now virtually impossible to change, extend, or grow. This book solves that problem by teaching developers real-world object oriented design techniques specifically focused on Ruby. Writing for Ruby developers at all levels of experience, Sandi Metz shares knowledge and concrete solutions for creating more extensible, more maintainable applications - and for fixing many of the poorly designed applications they must now manage. The first book to focus squarely on object-oriented Ruby application design, Practical Object Oriented Design in Ruby will guide developers to superior outcomes, even if their previous experience has been strictly limited to "procedural" techniques. Metz distills a lifetime of conversations about object-oriented design and many years of whiteboard drawings into a set of specific Ruby practices and patterns that lead to more manageable and pleasing code. 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.

About the Author

Sandi Metz has 30 years of experience working on projects that survived to grow and change. She writes code every day as a software architect at Duke University, where her team solves real problems for customers who have large object-oriented applications that have been evolving for 15 or more years. She’s committed to getting useful software out the door in extremely practical ways. Practical Object-Oriented Design in Ruby is the distillation of many years of white-board drawings and the logical culmination of a lifetime of conversations about OO design. Sandi has spoken at Ruby National and several times at Gotham Ruby User’s Conference and lives in Durham, NC.
