dialogue.multi-method 0.0.1

A small library to provide multi-methods. All functions are in the dialogue.multi_method package.

To create a multi-method, create a dispatch function, that takes the arguments and returns a hashable value, that is used to dispatch on. Use the @multi function annotation to annotate the function.

For each value of the dispatch function that you want to be handled differently, create a

An example:

@multi
def number(x):
  return x


@method(number, 1)
def number_one(x):
  return ''one'


@method(number)
def number_other(x):
  return "not one, but "+ str(c)


assert number(1) == 'one'
assert number(0) == 'not one, but 0'
