Module: Hooks

Included in:

HooksTest::TestClass, Middleman::Application

lib/vendored-middleman-deps/hooks-0.2.0/lib/hooks.rb,
lib/vendored-middleman-deps/hooks-0.2.0/lib/hooks/inheritable_attribute.rb

Overview

Almost like ActiveSupport::Callbacks but 76,6% less complex.

Example:

class CatWidget < Apotomo::Widget
  define_hook :after_dinner

Now you can add callbacks to your hook declaratively in your class.

after_dinner do puts "Ice cream!" end
after_dinner :have_a_desert   # => refers to CatWidget#have_a_desert

Running the callbacks happens on instances. It will run the block and #have_a_desert from above.

cat.run_hook :after_dinner

Defined Under Namespace
