module M1; end
module M2; end

class X
    include M1
    prepend M2
end

p X.ancestors
# => [M2, X, M1, Object, Kernel, BasicObject]

# Remove include module.
X.instance_eval { uninclude M1 }
p X.ancestors
# => [M2, X, Object, Kernel, BasicObject]
p X.ancestors.include? M1

p X.ancestors

p X.ancestors.include? M2
# => true


# Remove prepend module.

p X.ancestors.include? M2

X.extend M3
p X.singleton_class.ancestors
# => [#<Class:X>, M3, #<Class:Object>, #<Class:BasicObject>, Class, Module, Object, Kernel, BasicObject]

# Remove extend module.
X.unextend M3
p X.singleton_class.ancestors
# => [#<Class:X>, #<Class:Object>, #<Class:BasicObject>, Class, Module, Object, Kernel, BasicObject]
p X.singleton_class.ancestors.include? M3
# => false


# #extend with block
X.extend M1 do
    # mixin only in block.
    p X.singleton_class.ancestors
    # => [#<Class:X>, M1, #<Class:Object>, #<Class:BasicObject>, Class, Module, Object, Kernel, BasicObject]
end
p X.singleton_class.ancestors
# => [#<Class:X>, #<Class:Object>, #<Class:BasicObject>, Class, Module, Object, Kernel, BasicObject]
p X.singleton_class.ancestors.include? M1

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.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
