Can you try adding preview = true to your pyproject.toml, under [tool.ruff]?

Hm okay. This works for me but I use the old LSP (and vscode).

Can you try removing the

settings = {
    args = options.ruff_args,
  },

because the new server doesn't yet support options (but I'm just guessing at this point).

@snowsignal do you have an idea what's going on here?

Apr 08 '24 07:04 MichaReiser

@MichaReiser I try removing the

settings = {
    args = options.ruff_args,
  },

but it's still not working,ruff-lsp works good for me.

Apr 08 '24 09:04 a1401358759

Hey @a1401358759, I don't think the new server supporst configuring Ruff via the global --config flag or a local configuration file.

@snowsignal Correct me if I'm wrong here.

Apr 08 '24 11:04 dhruvmanila

@a1401358759 Right now the new server has a few limitations, especially around configuration. At the moment, we don't support configuring the server with the --config flag, nor do we support the args field in settings (like @dhruvmanila and @MichaReiser mentioned). Alternative configuration is something we're actively working on, but at the moment the configuration just defaults to any pyproject.toml / ruff.toml files at the root of your workspace or in parent folders.

Thank you for opening this issue - I'll follow up once we have a setting like this available.

Apr 09 '24 01:04 snowsignal

@snowsignal Okay, thank you very much for your answer.

Apr 09 '24 02:04 a1401358759

@a1401358759 Once https://github.com/astral-sh/ruff/pull/11140 lands in the next release, you should be able to specify a custom configuration file!

Here's what your LSP config could look like:

return {
  filetypes = { "python" },
  single_file_support = true,
  cmd = { "ruff", "server", "--preview", },
  settings = {
    configuration = "~/.config/nvim/pyproject.toml"
  },
}

The configuration setting is what you should use to specify the configuration file.

Let me know if you run into any more issues!

but ruff server still doesn't check E30* errors

Is there still a problem with my configuration?
