An API to pass data down in the sub-function inspired by React Context

pip install react-context

Inspired by this reddit, here a React Context-like API for Python to pass data down in thesub-function without polluting all the function parameters.

Under the hood it uses inspect.stack().frame to register the element in the context manager. Frames may be available only in CPython.

Define context values

To define a context value use use_context(**kargws) function

with use_context(something=123):
    ...

​

Retrieve the value somewhere in the code inside of the context

To retrieve the value, use get_context(key) function

Complete example

def nested_function():
    return get_context('something')

with use_context(something=123):
    value = nested_function()
    print(value) # 123

How to debug the context

To print in the console where a context has been defined in the stacktrace, replace get_context with debug_context(key, logger=print)

For the complete implementation and behaviour, please check the test file.
