pytel-inject 0.5.1

A bag of objects for Python

For when your object graph is too big

class A:
    def __init__(self, b: B):
        self.b = b

class B:
    pass

svc = {
    'a': A,
    'b': B,
}
context = Pytel(svc)
assert context.a.b == context.b

See usage for more cases

Features

• Build a graph of objects based on init methods or factory functions

• Initialize from

  • a dictionary of string to any of:

    • callable

    • type

    • value

  • Object containing any of:

    • object fields with objects or types (or callables)

    • class fields with objects or types (or callables)

    • methods

    • static methods

  • An Iterable of the above

• Verify integrity of the dependency graph using type annotations

• Recurrently resolve all dependencies at the first reference

• Works as a Context Manager, on __exit__ close all objects that are Context Managers

Because of strict type checking this package is probably quite unpythonic.
