[![Gem Version](https://badge.fury.io/rb/method_watcher.png)](http://badge.fury.io/rb/method_watcher)
[![Build Status](https://travis-ci.org/jjyr/method_watcher.png?branch=master)](https://travis-ci.org/jjyr/method_watcher)

Provide method\_overriding callback.

## Installation

Add this line to your application's Gemfile:

    gem 'method_watcher'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install method_watcher

## Usage

```ruby
require 'method_watcher'

class A
  include MethodWatcher
  def foo
  end
  
  def bar
  end

  watch_methods :foo, :bar
  unwatch_methods :bar
end

class B < A
  def foo
  end
end

#you will get a warning:
# => method A#foo is overridden

#you can define you own behavior when method overriding.
#in class A:
def self.method_overriding method
  raise "OMG, method #{method} is overridden!!"
end

#you can also use it like ruby core methods private, protect and public
require 'method_watcher'

class A
  include MethodWatcher

  # if you pass no arguments, all methods below it will be watched
  watch_methods

  def foo
  end

  def foo2
  end
  
  # if you pass no arguments, it will disable watching, methods below it will not be watched
  unwatch_methods

  def bar
  end

  #in this example, methods foo, foo2 should be watched
end
```
