== DESCRIPTION

NoBacksies is a callback layer built on top of Ruby's built-in callback

methods. It makes it possible to add new callbacks very easily, without

having to fuss with more nuanced issues of defining and redefining callback

methods.

== Compatability

NoBacksies does not currently work with *Rubinius*. Anyone know why?

== EXAMPLES

Here is a very simple example of how NoBacksies works.

  class Y

    include NoBacksies::Callbacks

    def self.list

      @list ||= []

    end

    callback :method_added do |method|

      list << method

    end

    def foo; end

    def bar; end

  end

  Y.list #=> [:foo, :bar]

Here is another example taken from the Anise[http://rubyworks.github.com/anise]

project.

  class Y

    include Anise

    include NoBacksies

    def self.doc(string)

      callback :method_added, :once=>true do |method|

        self.ann(method, :doc=>string)

      end

    end

    doc "foo is cool"

    def foo

      # ...

    end

  end

  Y.ann(:foo, :doc) #=> "foo is cool"

See the QED documentation for more examples.

== INSTALLATION

Install the RubyGems package in the usual fashion.

  $ gem install no_backsies

=== Donations

Software development is very time consuming. Rubyworks does a lot of FOSS 

development for el $0. We do it for the love of programming and

for Ruby. Any dollars that do come our way help us continue

the effort. So anything you may offer will help these projects such as this

continue to flourish. 

See the {Rubyworks Homepage}[http://rubyworks.github.com]. 

Thanks.
