encapsulation 0.2.0

Encapsulation and decorators made easy.

The encapsulation library

Introducing: the From class. For maintainable data pipelines.

Adds new syntactic sugar to python!

Installation

pip install -e encapsulation

Getting started

Get started by

from encapsulation.base import Maybe

Maybe("a") + "b" # outputs <Maybe val=(ab)>
Maybe(None) * 2 # outputs <Nothing val=(None)>

Easy to use decorators that elevate functions to return wrapped values instead:

from encapsulation.base import Maybe, to

def add1(n: int):
    return n + 1

@to(Maybe)
def (s: int):
    return s

test(1).bind(add1).effect(print) # prints '[2]'

You can chain computations using compose(). For example

from encapsulation.base import Just, compose

@to(Just[int])
def add2(s: int):
    return s

compose(Just(1), add2, add2) # equals Just(5)
