ruff config in pyproject.toml

[tvannahl]

Moin,

ruff is a fantastic tool with great defaults. Unfortunately there is one default, I do like to deviate from and typically I use the pyproject.toml for this configuration.

e.g.

[tool.ruff]
line-length = 80

Now if I execute ruff format .. directly in the command line, the pyproject.toml is automatically detected and formatting is configured accordingly. But this does not seem to be the case for the ruff meson plugin.

Does anyone have an Idea where I would need to start for such a configuration?

Same concern here. Worse, I prefer tabs than spaces... (put the guns down, please :) )

That said, I'm not completely sure if it's Mason's duties.

No judgment for as long as its formatted automatically ;-).

I've been able to solve the issue for me just now. Hoping it helps you as well:

1. It's not mason.vim who is doing the formatting. This is done by conform.nvim instead. You can check the formatter configuration using :ConformInfo.
2. There are more formatters than just one ruff formatter. I've configured most of them using the following configuration:

return {
  {
    "stevearc/conform.nvim",
    opts = {
      formatters_by_ft = {
        python = { "ruff", "ruff_organize_imports", "ruff_format" },
      },
    },
  },
}

great, thanks! I can confirm that the formatting now respects the project local config.

...Now, my concern was with linting :D
=> I kept having warnings "W191 indentation contains tabs".
=> it turns out that I used ruff_lsp that is now deprecated in favor of ruff

[tvannahl]

That's great. You're right with ruff_lsp vs ruff - it seemed to have been integrated recently.

On the W191 note, I guess adding the following to your pyproject.toml should fix that warning for you:

[tool.ruff.lint]
ignore = ["W191"]

I had to use this for the ruff to use my pyproject.toml config:

return {
  {
    "stevearc/conform.nvim",
    opts = {
      formatters_by_ft = {
        python = { "ruff_fix", "ruff_format" },
      },
    },
  },
}
