What happens if multiple plugins for formatting are installed?

[luator]

I use black for formatting and ruff for linting in many projects, hence I have both python-lsp-black and python-lsp-ruff installed. I now noticed that since some release, python-lsp-ruff has formatting enabled by default.

How does python-lsp-server handle this situation (i.e. two enabled plugins that can format). Are they both run one after another? If so, is there a defined order?

Okay, through experimentation I found out, that they indeed are both running. So I guess I need to find a way to dynamically disable ruff formatting if python-lsp-black is installed...
