How to use as black formatter?

[Joseph Reagle]

I currently use plugins LSP-ruff for linting and sublack for formatting. I've read ruff can now format using black conventions; can I use LSP-ruff to replace sublack? If so, how would I format that?

ruff advertises itself as formatter. That means you can just run the lsp_format_document command or add bind the command to a key:

{
        "keys": [
            "<your binding>"
        ],
        "command": "lsp_format_document"
    },

LSP does also have the lsp_format_on_save setting, which would run the command every time you save. You can also enable this behavior only for certain syntaxes by using the "Syntax Specific Settings" for that.
