Easy delegation with composition

Project description

Decorate a class with @delegate(attribute_name, method_names) to delegate the methods in method_names to the attribute attribute_name:

In [1]: from smartcompose import delegate

In [2]: @delegate('_n', ('__add__', '__mul__'))
   ...: class NumberWrapper:
   ...:     def __init__(self, n):
   ...:         self._n = n

In [3]: n = NumberWrapper(10)

In [4]: n + 2
Out[4]: 12

In [5]: n * 3
Out[5]: 30

For now, only compatible with Python 3.

pip install smartcompose
