EasyCallbacks

Easy example of how to implement callbacks for ruby regular methods.

Usage

Let´s take TDD flow as an example.

In TDD, you write your unit test first, watch it fail, and then implement code changes until the test passes.

class TDD
  def code
    puts 'Write the best code!'
  end
end

You can be sure to implement it well declaring the steps in this way:

  before_code :write_a_test
  around_code :drink_coffee
  after_code :clean_code_and_iterate

  def write_a_test
    puts 'Make it fail'
  end

  def drink_coffee
    yield
    puts 'Drink coffee'
  end

  def clean_code_and_iterate
    puts 'Refactor'
  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.
