Thanks. Actually, Emacs Elpy uses several common packages used to program Python in Emacs. It's just that it started failing for me a couple of months ago for different reasons so I thought it would be good to find a fallback editor.

However, I found out that there was something in my monolithic Emacs init.el causing autocompletion to fail. I haven't been able to pinpoint the configuration snippet that is causing the problem though. So I just ditched that init.el and started using different, short initialization files depending on the need, and now I can use Emacs Elpy again normaly.

Oh, yeah, I use Emacs launched from guix shell environments specific to my projects.

I think it is already possible. As far as I know, Emacs Elpy enables those features: linting, autocompletion, function signatures displayed for the function at point, displaying function documentation, and jumping to definition, some refactoring, ...

My current Elpy configuration is just this:

;; Enable Elpy IDE.
;; https://elpy.readthedocs.io/
;;
(elpy-enable)
(setq elpy-rpc-python-command "python3")  ; Is this still needed?

;; Use Flycheck instead of Flymake
;; (Flymake makes Emacs unresponsive unpredictably).
;;
(when (load "flycheck" t t)
  (setq elpy-modules (delq 'elpy-module-flymake elpy-modules))
  (add-hook 'elpy-mode-hook 'flycheck-mode))


Cheers,
