To use tangle in a project:
import tangle
If you are familiar with the Spring Framework, you may find the idea and mechanism of this framework quite easy to understand. Let's start with application context and bean:
application context(a.k.a.context): The IoC container which creates and manages the lifecycle ofbean.bean: A python object which is an instance of some class.configuration source: A class instance which defines a list of bean definitions.
Note that when we refer to bean, we focus on class instances, although python objects can be of any types (e.g. function, number, string, etc.). What about a class object as we know that it is also an instance of class (i.e. metaclass)? Well theoretically it should be OK to register class objects as beans in a context, but it is not fully tested. Therefore, it is NOT recommended to use tangle to manage class objects (maybe in the future).
When you apply tangle to your python program, the program may contain one or several context, and many bean. If you want to use the beans, use the get(bean_id) method of the context to obtain a bean instance. The bean_id is provided by your configuration source.
