# AfterDo [![Build Status](https://travis-ci.org/PragTob/after_do.png?branch=master)](https://travis-ci.org/PragTob/after_do)[![Code Climate](https://codeclimate.com/github/PragTob/after_do.png)](https://codeclimate.com/github/PragTob/after_do)

AfterDo is simple gem, that allows you to execute a specified block after specified method of a class are called. If the class extends `AfterDo` you can simply do this by `MyClass.after :some_method do puts 'whatever you want?' end`

This shall not be done to to alter behavior or something but rather to fight cross-cutting concerns such as logging. E.g. with logging you litter all your code wit logging statements - that concern is spread over many files. With AfterDo you could put all the logging in one file.

AfterDo has no external runtime dependencies and the code is just a bit more than 60 lines (blank lines included).

## Installation

Add this line to your application's Gemfile:

    gem 'after_do'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install after_do

## Usage

With AfterDo you can do simple things like putting something out everything a method is called as in this example:

```ruby
class Dog
  def bark
    puts 'Woooof'
  end

  def eat
    puts 'yummie!'
  end
end

Dog.extend AfterDo
Dog.after :bark do puts 'I just heard a dog bark!' end

dog = Dog.new
dog2 = Dog.new

dog.bark
dog.eat
dog2.bark

# Output is:
# Woooof
# I just heard a dog bark!
# yummie!
# Woooof
# I just heard a dog bark!

```

## Is there a before method?

No not yet, I didn't have a use case for it yet. If you have one please let me know, it is relatively easy to add.
