A simple way to inject composition through inheritance syntax.

Project description


A simple way to inject composition through inheritance syntax.


The following links served as inpiration during the writing of this, and as a in-depth explanation of what actually is composition and its benefits and drawbacks versus inheritance.


From the inspirations one can easily see that an older implementation of compositional forwarding exists (forwardable) so why would I do this to myself? In short, I didn't like the syntax introduced by it. I find the syntax provided by this implementation a bit easier to understand as I find adding things that related to properties of a class inside the brackets in the class statement the most logical.


from pycompose import Compose

class A:
    test1 = "123"

    def hello(self):

    def __repr__(self):
        return "<A>"

class B:
    test2 = "456"

    def hello(self):

    def __repr__(self):
        return "<B>"

class C(
    Compose(A, "test1", ("hello", "helloA")),
    Compose(B, "test2", ("hello", "helloB"), name="b_object"),

c = C()
print(c.test1 + c.test2)  # > 123456
c.helloA()                # > A
c.helloB()                # > B
print(c._a, c.b_object)   # > <A> <B>


Please do note that this project is but a small abstraction for something that can easily be achieved only a few more lines of hand written code. As such I am aware of the fact that this may seem pretty useless to some people.
