Add this line to your application's Gemfile:
And then execute:
$ bundle install
Or install it yourself as:
$ gem install extend_bang
This gems add the
extend! method to
Object. This method behaves the same way as
extend, except overrides existing methods.
require "extend_bang" to the top of your file to get started.
If you're using rails, the autoloading should handle this for you.
require "extend_bang" module Foo def self.test "Foo Test" end end module Bar def test "Bar Test" end end # Here we extend `Foo`'s singleton class with `Bar`. Foo.extend Bar # We can see here that although we re-define `test`, it maintains `Foo`'s initial implementation. p Foo.test # => "Foo Test" # Now, if we use `#extend!`, we can make it override the method Foo.extend! Bar p Foo.test # => "Bar Test"

bin/setup to install dependencies. Then, run
