Re: Trouble producing nicely aligned org tables from emacs-jupyter code blocks using latest org version

["Richard H. Stanton" <rhstanton@berkeley.edu>]

Here’s a simple init.el that shows the problem (most of it is just boilerplate code to use straight.el to manage packages, and you may need to edit the python executable path).

-------------------

;;; straight
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

;;  Replace use-package with straight-use-package
(straight-use-package 'use-package)
(setq straight-use-package-by-default t)
(setq use-package-verbose t)
(straight-use-package 'use-package-ensure-system-package)


;;; Which org-mode to use?

; (straight-use-package '(org :type git :repo "https://code.orgmode.org/bzg/org-mode.git"))
(straight-use-package '(org :type built-in))

;;; Find python executable
(setq exec-path (append '("/Users/stanton/anaconda3/bin") exec-path))

(use-package org
  :after (jupyter)
  :straight t
  :config
  (org-babel-do-load-languages
   'org-babel-load-languages
   '((python . t)
     (jupyter . t))))

(use-package jupyter)

;; Make cursor more visible when you move a long distance
(use-package beacon :config (beacon-mode 1))

——————————

Now execute the following source block and you’ll see the misaligned table.

#+begin_src jupyter-python :async yes :session py
[['aaaaaaa', 'a'], None, ['b', 'b']]
#+end_src

Commenting out the last line of init.el, thus not loading the beacon package, gets things to work OK. But so does changing which version of org mode is loaded by commenting out one of the lines and uncommenting the other, so this is not only about the beacon package.

Best,

Richard

In that case, the tables don’t format quite right, as I noted. But if I add the header ":async nil", the table comes out fine. Table formatting is OK in python blocks with or without asynchronous execution.
