Ruby for Rails: Ruby Techniques for Rail Developers
Ruby for Rails developers achieve Ruby mastery. Each chapter deepens your Ruby knowledge and shows you how it connects to Rails. You will gain confidence working with objects and classes and learn how to leverage Ruby s elegant, expressive syntax for Rails application power. And you will become a better Rails developer through a deep understanding of the design of Rails itself and how to take advantage of it.
Ruby Under a Microscope
Ruby is a powerful programming language with a focus on simplicity, but beneath its elegant syntax it performs countless unseen tasks. Ruby Under a Microscope gives you a hands-on look at Ruby’s core, using extensive diagrams and thorough explanations to show you how Ruby is implemented (no C skills required). Author Pat Shaughnessy takes a scientific approach, laying out a series of experiments with Ruby code to take you behind the scenes of how programming languages work. You’ll even find information on JRuby and Rubinius (two alternative implementations of Ruby), as well as in-depth explorations of Ruby’s garbage collection algorithm. Ruby Under a Microscope will teach you: –How a few computer science concepts underpin Ruby’s complex implementation –How Ruby executes your code using a virtual machine –How classes and modules are the same inside Ruby –How Ruby employs algorithms originally developed for Lisp –How Ruby uses grammar rules to parse and understand your code –How your Ruby code is translated into a different language by a compiler No programming language needs to be a black box. Whether you’re already intrigued by language implementation or just want to dig deeper into Ruby, you’ll find Ruby Under a Microscope a fascinating way to become a better programmer. Covers Ruby 2.x, 1.9 and 1.8
Practical Object-oriented Design in Ruby
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. This book focuses 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
