chorny

Chorny (russian: чёрный) is a loader of Black that patches code on the fly to change the formatting to satisfy Athenian's conventions.

So far, the only difference with the original rules is how magic trailing commas work. Chorny prevents new line expansion by the magic trailing comma for parentheses unless the code is a function signature. Example:

async def foo(self, arg, other,):
    pass

becomes

async def foo(
    self,
    arg,
    other,
):
    pass

However,

foo(
    1, "one,
)

stays intact.

Installation

pip install chorny

Usage

chorny patches and launches black and should be used the same way.
