The default mode is fundamental, which is not really comfortable to edit elisp code did I miss something ?

  • @JeanPierre provides code to switch to emacs-lisp-mode for editing table formulas. You cannot switch to emacs-lisp-mode without 'turning-off' the table-editing commands provided by org-mode. You can add individual features from elisp-mode, or at least keybindings. Are there particular parts of emacs-lisp-mode you want to have access to? We might be able to help you set them up. – Tyler Apr 13 '17 at 16:44

A first idea is to to use an after advice to ensure emacs-lisp-mode is turned on after org-table-edit-formulas is run.

 (advice-add #'org-table-edit-formulas :after #'emacs-lisp-mode)

However, this does not work well. Examining the source of the function (in file org-table.el) shows that it turns fundamental-mode on then sets up a few things (variables and keybindings) that the call to emacs-lisp-mode will undo.

We want to call emacs-lisp-mode just after (or ideally, instead of) the call to fundamental mode in org-table-edit-formulas. Here's how to do it:

(defun my--advice-for-edit-formulas (orig-fun &rest args)
  (advice-add #'fundamental-mode :after #'emacs-lisp-mode)
  (apply orig-fun args)
  (advice-remove #'fundamental-mode #'emacs-lisp-mode))

(advice-add #'org-table-edit-formulas :around #'my--advice-for-edit-formulas)

We set an around advice to org-table-edit-formulas whose job is to:

  1. add an after advice to fundamental-mode to make it run emacs-lisp-mode,

  2. call org-table-edit-formulas,

  3. remove the advice to fundamental-mode.

This way, fundamental-mode calls emacs-lisp-mode only when itself called from org-table-edit-formulas.

Now it's possible it would be better to add an option to choose the mode org-table-edit-formulas will use, or to make it automatically select emacs-lisp-mode when the formulas are in elisp.

  • Thank you for your interest, but the problem il the same if I active emacs-lisp-mode while interactive. C-c ' is no longer bound to org-table-fedit-finish and all edits are lost. – gigiair Apr 13 '17 at 14:35
  • Looking at org-table.el, I think that calling emacs-lisp-mode after the function cancels a number of things the function has set up (including bindings, but also variables), so this indeed not a viable solution. – JeanPierre Apr 13 '17 at 18:37
  • A "brute force" solution could be to copy the function org-table-edit-formulas from file org-table.el, change the call to fundamental-mode by emacs-lisp-mode and use that definition to override the one from org-table.el. I think this should work, but may break later when other things change in org-table.el. – JeanPierre Apr 13 '17 at 18:40
  • How about this? (defun my--advice-for-edit-formulas (orig-fun &rest args) (advice-add #'fundamental-mode :after #'emacs-lisp-mode) (apply orig-fun args) (advice-remove #'fundamental-mode #'emacs-lisp-mode)) (advice-add #'org-table-edit-formulas :around #'my--advice-for-edit-formulas) – JeanPierre Apr 13 '17 at 18:51
  • I just tried. It looks fine. many thanks. – gigiair Apr 14 '17 at 11:41
