Description
This is a backward incompatible fork of https://github.com/djberg96/interface It provides interfaces, traits and runtime interface checks in Ruby
Installation
gem install rubycube OR
gem rubycube in your Gemfile
Theory
Synopsis
General Notes
Since runtime checks are meant to be invoked for every invocation of a method,
there is a runtime overhead associated which may not be desirable in
production. Hence these checks are guarded by an environment variable
RUBY_CUBE_TYPECHECK. Unless this variable is set to 1, the runtime
checks are not executed
Runtime performance of check methods
On a Macbook Pro 2.4 GHz Intel Core i5 machine, enabling runtime checks costs about 1 second for every million calls. YMMV. It is advisable to benchmark for your code to determine if the overhead is acceptable in your enviroment.
Developer's Notes (from the original repository)
A discussion on IRC with Mauricio Fernandez got us talking about traits. During that discussion I remembered a blog entry by David Naseby. I revisited his blog entry and took a closer look:
http://ruby-naseby.blogspot.com/2008/11/traits-in-ruby.html
Keep in mind that I also happened to be thinking about Java at the moment because of a recent job switch that involved coding in Java. I was also trying to figure out what the purpose of interfaces were.
As I read the first page of David Naseby's article I realized that, whether intended or not, he had implemented a rudimentary form of interfaces for Ruby. When I discovered this, I talked about it some more with Mauricio and he and I (mostly him) fleshed out the rest of the module, including some syntax improvements. The result is syntax and functionality that is nearly identical to Java.
I should note that, although I am listed as the author, this was mostly the combined work of David Naseby and Mauricio Fernandez. I just happened to be the guy that put it all together.
Acknowledgements (from the original repository)
This module was largely inspired and somewhat copied from a post by David Naseby (see URL above). It was subsequently modified almost entirely by Mauricio Fernandez through a series of discussions on IRC.
