When working on python code in elpy, I like to have the python shell open.

Often I don't want the *Python* buffer to be visible, especially with several buffers with Python code or long Python files open.

I found the package eshell-toggle which is basically doing the same for eshell buffers what I would find useful for the *Python* buffer.

  1. If eshell-toggle’d buffer is already visible in frame for current buffer then select (toggled) eshell window.
  2. If current window is (toggled) eshell itself then hide it.

Is there a good way to toggle the *Python* buffer?

    It seems relatively easy to write some functions that would do what you want. Leverage the functions elpy-shell-switch-to-shell and delete-window.

  • How about (switch-to-buffer "*Python*")"? Or switch-to-buffer-other-window. Sep 9 at 13:39

I'm not so familar with elisp, but as aadcg pointed out that elpy-shell-switch-to-shell and delete-window might work I gave it a try.

(defun python-toggle ()
  (interactive)
  (cond ((equal (buffer-name) "*Python*") (delete-window))
        ((get-buffer "*Python*") (elpy-shell-switch-to-shell))
        ((derived-mode-p 'python-mode) (run-python))
        (t (message "Not in python-mode."))))

With this function toggling the *Python* buffer works.

If you want to bring the *Python* buffer to front when sending code via any elpy-shell-send-* function, you need to set (setq elpy-shell-display-buffer-after-send t)

But as I'm not familiar with elisp this code can probably be improved quite a bit.

    (buffer-local-value 'major-mode (get-buffer (current-buffer))) is just major-mode. Instead of comparing strings, you can compare symbols: (eq major-mode 'python-mode). But in fact this should be (derived-mode-p 'python-mode). Sep 9 at 19:26
  • @Gilles'SO-stopbeingevil' thanks for pointing that out! That's indeed better.

    @wuff nested conditionals are a bit hard to read. Consider using cond, instead of if.

  • @aadcg Indeed, using cond makes it more readable! Thanks!

  • I'll mark it as solved now after all your suggestions! This answer is actually more the contribution of aadcg and Gilles'SO-stopbeingevil' than mine! Thanks a lot!
