Did you check existing requests?

Describe the feature

Actually ruff_format formatter does not work with the native ruff language server but only with the CLI.

Provide background

See issue on Ruff astral-sh/ruff#12514

What is the significance of this feature?

strongly desired

Additional details

My actual config is:

local M = {
  'stevearc/conform.nvim'
}

function M.config()
  require("conform").setup({
    formatters_by_ft = {
      -- python = {'ruff_organize_imports', 'ruff_format'},
    },
    format_after_save = {
      lsp_format = "fallback",
    },
    notify_on_error = true,
  })
end

return M

I'm not specifying any formatter in order to fall back to the LSP. This way I can format with the native Ruff server but I can't organize imports.

EDIT: Also added the following autocommand to sort imports:

vim.api.nvim_create_autocmd({ "BufWritePost" }, {
  pattern = { "*.py" },
  callback = function()
    vim.lsp.buf.code_action {
      context = {
        only = { 'source.organizeImports.ruff' },
      },
      apply = true,
    }
  end,
})

Maybe this can be integrated in Conform somehow?
