Cpyfunctional 0.0.2

Python version

This module work on 3.4+. Fully tested on python 3.5.2.

compose

compose is a function to execute any callable one by one chaining from last callable to first. This function accept any callable and execute it from last callable to the first and pass every result to next callable until the last.

def inc(number: int) -> int:
    return number + 1

def square(number: int) -> int:
    return number ** 2

cpyfunctional.compose(inc, square)(3) # 10
cpyfunctional.compose(square, inc)(3) # 16

As you can see, it execute callable from last to first. You can also use lambda instead of creating function.

cpyfunctional.compose(lambda number: number + 1, lambda number: number ** 2)(3) # 10

pipe

This function has same functionality to compose but execute callable from first to last.

def inc(number: int) -> int:
    return number + 1

def square(number: int) -> int:
    return number ** 2

cpyfunctional.pipe(inc, square)(3) # 16
cpyfunctional.pipe(square, inc)(3) # 10

func_curry

func_curry is a function to add parameter to callable that called by compose or pipe. This function accept a callable that accept parameter and push previous value to related callable and execute it.

def inc(number: int) -> int:
    return number + 1

def multiple(multiplier: int, prev_number: int) -> int:
    return prev_number * multiplier

cpyfunctional.compose(inc, func_curry(multiple)(6))(3) # 19

This example show that now callable are able to accept any parameter not only from previous result.
