strange characters in the output when there's errors #465

Closed yitang closed 1 year ago

Thanks for providing this useful package that enables me to stick with org-mode.

I'm having one small issue I started to see when using emacs-jupyter but it might not relate to it at all.

as the below screenshot shows, there are some strange characters, "^[[0;32m" for example, in the output block. it only happens when there's error. image

what's the possible causes of it? and how to keep the error message clean and useful?

Thanks,

I had a similar problem, and fixed it with this org-mode hook:

(use-package org
  :straight t
  :init
  (defun display-ansi-colors ()
    "Fixes kernel output in emacs-jupyter"
    (ansi-color-apply-on-region (point-min) (point-max)))
  :hook
  (org-mode . (lambda () ( (add-hook 'org-babel-after-execute-hook #'display-ansi-colors)))))

This is the same issues as #380 which was fixed in this commit, so you might want to remove the work around once you upgrade past that commit.
