encapsulation 0.1.3

Encapsulation and decorators made easy.

The encapsulation library

Introducing: the From class.

Decorators made easy, piece-wise oprations on product types, controlling evaluation order.

For maintainable data pipelines.

It's a monad (sorry 🍪).

Installation

pip install -e encapsulation

Getting started

Get started by

from encapsulation.base import From

obj = From(
    lambda x: "hi " + x        
    )("there")

print(obj)

Easy decorator superpowers:

from encapsulation.base import From

def inspect(x: str): 
    """some function you want to call each time"""
    print(x)

def compose(func, *args):
    inspect(func)
    func(*args)

# you can also turn inspect into a proper decorator using
agent = From(Fn=compose).apply

@agent
def task(val: str):
    """Some task"""
    print("[this is a task]")

task("hiho")

The above will both evaluate task("hiho") and leave its return type untouched, while also executing agent(task) each time the task function gets called.

Congratulations! You can now stop writing convoluted wrappers each time you want to implement a decorator, and use From instead 😎
