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.\n\nI use the following config in emacs:\n\n```\n  (with-eval-after-load 'eglot\n    (add-to-list 'eglot-server-programs\n                 '(python-base-mode . (\"pylsp\" :initializationOptions\n  (:pylsp (:plugins (:ruff\n                     (:enabled t\n                      :formatEnabled t))))))))\n```\n\n\nBelow is a log of a short session where I try to format and ask for fixes.\n\n----- Start log ----\n[jsonrpc] D[00:18:10.925] Running language server: pylsp\n[jsonrpc] e[00:18:10.925] --\u003e initialize[1]
