Quick fixes and autoformat do not work from emacs

[rjekker]

When using python-lsp-ruff from emacs with eglot, most things work fine, including autocomplete, linting, jump to definition. Two things do not work at all, though: auto-formatting and quick fixes. Those do work when I use the ruff server, so they are supported by eglot/emacs.

I use the following config in emacs:

  (with-eval-after-load 'eglot
    (add-to-list 'eglot-server-programs
                 '(python-base-mode . ("pylsp" :initializationOptions
  (:pylsp (:plugins (:ruff
                     (:enabled t
                      :formatEnabled t))))))))

Below is a log of a short session where I try to format and ask for fixes.
