h2. Ruby design patterns

This repository is a collection of working examples of the "Gang of Four Design Patterns":http://www.amazon.co.uk/Design-patterns-elements-reusable-object-oriented/dp/0201633612/ written in Ruby. I am doing this as part of my personal studying and preparation for a weekly design patterns discussion at "Eden Development":http://edendevelopment.co.uk.

Sometimes i follow the pattern given in the book, other times i make up my own. As a study group, we are working through the book in the order suggested by "A Learning Guide To Design Patterns":http://www.industriallogic.com/papers/learning.html so my examples will probably appear in the same order.

My examples have tests which can be run by running @test.rb@ in the appropriate directory. For example:

ruby behavioral_patterns/strategy/test.rb

These are the patterns that i have implemented so far:

• The basic "creational non-pattern":http://github.com/sermoa/ruby_design_patterns/tree/master/creational_patterns/basic/ used as a basis for the rest of the creational patterns
• "Factory Method":http://github.com/sermoa/ruby_design_patterns/tree/master/creational_patterns/factory_method/
• "Strategy":http://github.com/sermoa/ruby_design_patterns/tree/master/behavioral_patterns/strategy/
• "Decorator":http://github.com/sermoa/ruby_design_patterns/tree/master/structural_patterns/decorator/
• "Composite":http://github.com/sermoa/ruby_design_patterns/tree/master/structural_patterns/composite/
• "Iterator":http://github.com/sermoa/ruby_design_patterns/tree/master/behavioral_patterns/iterator/
• "Template Method":http://github.com/sermoa/ruby_design_patterns/tree/master/behavioral_patterns/template_method/
• "Abstract Factory":http://github.com/sermoa/ruby_design_patterns/tree/master/creational_patterns/abstract_factory/
• "Builder":http://github.com/sermoa/ruby_design_patterns/tree/master/creational_patterns/builder/
• "Singleton":http://github.com/sermoa/ruby_design_patterns/tree/master/creational_patterns/singleton/

Please feel welcome to comment, add your feedback, suggest alternative implementations, point out my errors, and of course use for your own study and benefit.
