multidispatch

Very basic multidispatch in Ruby using natural syntax. Currently supports overloads by count of mandatory parameters. So, it solves only one problem. Converts the following code:

class BoilerplateClass
  def foo(a = nil, b = nil)
    unless a || b
      # do action 1
      # ...
    end
    if a && !b
      # do action 2
      # ...
    end
    if a && b
      # do action 3
      # ...
    end
  end
end

to this nice one:

class MultidispatchClass
  include Multidispatch

  def foo
    # do action 1
    # ...
  end

  def foo(a)
    # do action 2
    # ...
  end

  def foo(a,b)
    # do action 3
    # ...
  end
end

Add this line to your application's Gemfile:

gem 'multidispatch'

And then execute:

$ bundle

Or install it yourself as:

$ gem install multidispatch

See sample/ folder:

• morning.rb - sample class using multidispatch module
• main.rb - quick CLI test for Morning
• Gemfile - sample gemfile

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

... do not forget tests ... and Happy Hacking!
