How do I reference a function in Ruby?

Question

In python, it\'s fairly straightforward to reference a function:

>>> def foo():
...     print \"foo called\"
...     return 1
... 
>>> x =          


        

Answer 1

You can use the method instance method inherited from Object to retrieve a Method object, which essentially is a Proc object which you can invoke call on.

In the console, you'd do this:

fooMethod = self.method(:foo) #fooMethod is a Method object

fooMethod.call #invokes fooMethod
