Allows you to turn any method that yields, into a method that accepts no block and returns an enumerator instead.

Add this line to your application's Gemfile:

gem 'as_enum'

And then execute:

$ bundle

Or install it yourself as:

$ gem install as_enum

class Cow
  as_enum def each_thing(x)
    yield x
  end
end

cow = Cow.new
enum = cow.each_thing(5) # => #<Enumerator: #<Cow:0x007fdb74807dc8>:each_thing(5)>
enum.next # => 5

as_enum monkey patches Module by default. If this is unwanted, require as_enum/source instead, and you'll be able to use as_enum as follows:

class Cow
  AsEnum.as_enum self, def each_thing(x)
    yield x
  end
end

cow = Cow.new
enum = cow.each_thing(5) # => #<Enumerator: #<Cow:0x007fdb74807dc8>:each_thing(5)>
enum.next # => 5
