ninja_decorators¶ ↑

github.com/haruska/ninja-decorators

Implements before_filter, after_filter, and around_filter decorators similar to Rails but can be used anywhere

Currently, only around_filter is implemented. Also, need to change syntax to :only and :except filters similar to Rails

Similar to Rails, the following will execute the method common_around around both the foo and bar methods:

require 'rubygems'
require 'ninja_decorators'

class NinjaClass
  include NinjaDecorators

  attr_accessor :ret

  around_filter :common_around, [:foo, :bar]

  def foo
    @ret += "foo"
  end

  def bar
    @ret += "bar"
  end

  private

  def common_around
    @ret = "common "
    yield
    @ret += " around"
  end
end

produces

irb(main):076:0> n = NinjaClass.new
=> #
irb(main):077:0> n.bar
=> "common bar around"
irb(main):078:0> n.foo
=> "common foo around"

rubygems

sudo gem install haruska-ninja-decorators
