I know ruby treat an object as false whenever it is nil or false.
However, I wonder if there are any other ways to change this behavior.
For example, I define a class called AreYouOk.
@ok = ok
x = AreYouOk.new(false)
puts “you are ok” if x
Since x is not nil, ruby prints " you are ok".
However, I want ruby to make the decision based on the @ok instance
variable. Are there any ways to do that?
I know that there is a method called bool in Python. You can define
your bool method in your class. The truth value of an object is
based on the return value of bool. Does ruby provide similar
