It’s a stand-alone Nova extension to use Ruff, an extremely fast Python linter (and formatter), written in Rust.
Before using the extension, it’s necessary to install Ruff itself if you don’t have one already.
Ruff can be installed simply by running pip install ruff.
The extension supports both global and workspace configurations. A workspace configuration always overrides a global one.
There are few options available to configure: executable path, check command arguments,
and check mode, format command arguments, and format on save. By default, the executable
path is /usr/local/bin/ruff, with no additional arguments, checking on change, and
formatting on save.
You could alter the executable path if Ruff 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 ruff becomes
the first argument.
The extension respects pyproject.toml, ruff.toml, and .ruff.toml in a project
directory as much as ruff command-line utility. So, there’s no need to specify the
--config argument explicitly.
