It’s a stand-alone Nova extension to use Black, the uncompromising Python code formatter.
Before using the extension, it’s necessary to install Black itself if you don’t have one already.
Black can be installed simply by running pip install black.
The extension supports both global and workspace configurations. A workspace configuration always overrides a global one.
There are three options available to configure: executable path, command arguments,
and format on save. By default, the executable path is /usr/local/bin/black, with no
additional arguments, and formatting on saving is on.
You could alter the executable path if Black installed in a different place
or if /usr/bin/env usage is desirable.
In the case of /usr/bin/env, it becomes the executable path, and black becomes
the first argument.
Also, the extension respects pyproject.toml in a project directory. So, there’s no
need to specify the --config argument explicitly.
