Build Status

Simple AOP implementation for Ruby

Installation

Add this line to your application's Gemfile:

gem 'simple_aspect'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple_aspect

Usage

require 'simple_aspect'

class Worker
  extend SimpleAspect

  aspect_around :perform do |*args, &original|
    puts "Before: \"args\" => #{args}"
    result = original.call # Don't forget to `call` the original implementation
    puts "After: \"result\" => #{result}, \"args\" => #{args}"
  end

  def perform(n1, n2)
    puts 'doing something'
    yield if block_given?
    n1 + n2
  end
end

or

require 'simple_aspect'

class Worker
  extend SimpleAspect

  aspect_around :perform, :around_perform

  def perform(n1, n2)
    puts 'doing something'
    yield if block_given?
    n1 + n2
  end

  private

  def around_perform(*args)
    puts "Before: \"args\" => #{args}"
    result = yield # Don't forget to execute the original implementation
    puts "After: \"result\" => #{result}, \"args\" => #{args}"
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
