smarti 1.2.14

A smart and lightweight dependency injector

Smarti - Smart Dependency Injection for Python

Just add the @autowired decorator to the class you want to autoload. To customize the loaded arguments (e.g., input specific enum value, with the argument name number) add it to the decorator like so @autowire(number=Enum.one).

Furthermore, you can override/pass down arguments recursively using name_kwargs. This will use the given parameters to initialize name.

All of the described ways to modify the used arguments are also applicable when initializing the class. This means that you could call an autoloaded class using A(a=4, b_kwargs={'x' = 3}) to modify local usage. These override the corresponding defaults of the decorator of class A.

When using singletons, different parameters will yield different instances, but the same will yield the same.

Everything is thread-safe when the ClassLoaderFlags.ALL_DEPENDENCIES_AUTOWIRED is specified. Additionally, this forces you to decorate the whole dependency tree. When using this flag, non-autowired classes raise a RuntimeError. To avoid such errors, use ClassLoaderFlags.IGNORE_POSSIBLE_THREAD_ERRORS, but it is not recommended.

Installs via pip:

pip install smarti
