Pipe.py

A non-intrusive Python pipeline.

There are only pipeline. If you want more functional tools, you should look for another library.

This code repository has been moved to Cool, where it is actively maintained and there are more similar tools.

Install

pip install only-pipe

Or fetch from github

pip install git+https://github.com/abersheeran/only-pipe

Usage

Use pipeline to pass data as a positional parameter to the next function:

from pipe import F

range(10) | F(filter, lambda x: x % 2) | F(sum) == 25

Or you need to pass multiple parameters through the pipeline:

from pipe import FF


def get_data():
    return 1, 2


get_data() | FF(lambda x, y: x + y) == 3

Use alias like follow code, you can use map/filter/reduce more conveniently:

from functools import reduce
from pipe import F

Filter = F(F, filter)
Map = F(F, map)
Reduce = F(F, reduce)

range(100) | Filter(lambda x: x % 2) | Map(lambda x: x * x) | Reduce(lambda x, y: x + y)

Set Global

Maybe you don't want to use from pipe import F in every file of the entire project, you can use the following code to set it as a global function, just like min/max/sum.

import pipe

pipe.set_global(pipe.F, pipe.FF)

Maybe you also want to expose functools.reduce to the world, just like map/filter.

import pipe
import functools

pipe.set_global(pipe.F, pipe.FF, functools.reduce)

More

No more ~ This library has less than ten lines of valid code, but it is very effective.

If you like it, please give a Star. 😀
