Discussion on: Your bash scripts are rubbish, use another language

I think so, too. You can make a nice 'fluent' DSL out of it, though.

class Chain:
        def __init__(self, *fns):
                self.fns = fns
        def __or__(self, fn):
                return Chain(*self.fns, fn)
        def __call__(self, arg):
                return reduce(lambda ret, f: f(ret), self.fns, arg)

Chain() | read_file | create_filter("https://") | web_get

def double(x):
        return 2*x

def fromstr(s):
        return int(s)

def inc(x):
        return x+1

def repeat(n):
        return lambda s: s * n

c = Chain() | fromstr | inc | double | str | repeat(3)

assert c("1") == "444"
assert c("20") == "424242"

..... ingenious.

I'm still trying to brain this, its possibilities and its limitations but... wow.

A bit of commentary would be very welcome :-)

[xtofl]

I'll expand it in a full fledged post :) Or 'leave it as an exercise'?

I either love this or hate it, I can't decide. Bravo, sir!

Somehow, I have hit the 'publish' button on dev.to/xtofl/i-want-my-bash-pipe-34i2.

I've only skimmed the article so far, but it looks like a good one. I like the title! 😁

@xtofl , @Cliff , I have finally gotten round to this, I think you will be gleefully dismayed.
