Using Black as text filter

[Maxime Pigeon]

Hi,

I'm trying to create a very simple text filter that uses Black to format Python code. According to their documentation, Black supports formatting code via stdin, with the result being printed to stdout. So my text filter is simply:

#!/bin/bash

black -

Script output says that the reformat was successful, yet my file doesn't change. Anyone has experience with using Black in BBEdit?

For reference, I ended up using Black's (private) method format_str() like so:

#!/usr/bin/env python3

import sys

from black import format_str

from black.mode import Mode

stdin = sys.stdin.read()

stdout = format_str(stdin, mode=Mode())

print(stdout, end="")

Still, it would be nice to know what's wrong with the previous code.

Hi Maxime,

Passing the --quiet flag seems to do the trick.

#!/bin/bash

black -q -
