像写 shell 一样写 Python

[czheo]

from functools import partial

ret = None

class pipe:
    def __init__(self, data):
        self.data = data

    def __or__(self, right):
        if right is ret:
            return self.data
        elif isinstance(right, tuple):
            return pipe(partial(*right)(self.data))
        else:
            return pipe(right(self.data))

# with partial function
pipe(10) | range | partial(map, lambda x: x ** 2) | list | print
# simplify partial function
pipe(10) | range | (map, lambda x: x ** 2) | list | print
# assign return value to x
x = pipe(10) | range | (map, lambda x: x ** 2) | list | ret

想像写 python 一样写 shell 才是需求啊...

@Sequencer Just for fun. 再来一个例子：
···
from itertools import groupby
{k: list(v) for k, v in pipe([4,3,1,3,4,2,1,9]) | sorted | groupby | ret}
## {1: [1, 1], 2: [2], 3: [3, 3], 4: [4, 4], 9: [9]}
···

@Sequencer shellpy

重载 or 操作符 可以可以

[mingyun]

@Sequencer 赞同

[franklinyu]

@itfanr 你說的 shellpy 能改環境變量麼？

[itfanr]

@franklinyu 自己试试呗
