No Backsies
DESCRIPTION
NoBackies 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.
RESOURCES
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 ; end
end
Y.list #=> [:foo, :bar]
Here is another example taken from the 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.
