Object#in?
A monkeypatch on Object which adds the instance method in?
, which is
effectively the standard library Array#include?
method with the subject
and object inverted i.e. so the object you're search for receives the method
call.
Installation
Add this line to your application's Gemfile:
gem 'object-in'
And then execute:
$ bundle
Or install it yourself as:
$ gem install object-in
Usage
This adds to Object, so it will be available on (essentially?) everything. It takes one parameter, the array you want to check for the object's inclusion in.
array = %w{yankee doodle doo}
"yankee".in? array # => true
"da".in? array # => false
yankee.in? array.join(" ") # => raises a TypeError exception
- It returns true if the array passed in includes the object.
- It returns false if the array passed in doesn't include the object.
- It raises a TypeError exception if the passed in object isn't an Array
