How to make undo work in the scratch buffer
  • Maybe you can try to fix your issue by forcing the buffer-undo-list variable to nil for the elisp mode, as follow: (add-hook 'elisp-mode (lambda () (setq-local buffer-undo-list nil)))

    I tried it but still no joy...

    Looking at this issue I noticed 3 things that may help to pinpoint the origin...:

    • I have 2 variables set that affect the scratch buffer in my config (without yours, that it's the 3rd):
                      (setq initial-major-mode 'org-mode)
                      (setq-default major-mode 'org-mode)
    
    • Before this reply, (setq-default major-mode 'org-mode) was (setq default-major-mode 'org-mode). Both expressions seems indistinguishable in the resulted behavior.
    • The scratch buffer starts in org-roam mode (and read-only mode), which is very strange, but can obviously be related and/or part of the problem. The org-roam section (my config is literate in org-mode) comes before this variables being set.

    What does this info may imply?

  • Hi @ouigol@beehaw.org.

    I'm using vanilla emacs with my own configuration. And replying to Sunoc made me remember that the scratch buffer starts as read-only and not in org-mode. So it seems it comes from there... I'll have to bissect it?

    Thanks a lot... :)

  • Hello Sunoc.

    • the buffer is not in read-only, but it always start as so.
    • the keybinding is ok since it works in all the rest of the buffers.
    • Upon calling undo, emacs says "no undo information in this buffer" (searching for this didn't seem to give relevant information except something from 2006 and then something about specific of a table-spreadsheet that I don't use).

    From this and @ouigol@beehaw.org (I will relpy after this one) it looks that it may be my configuration, since I'm using vanilla emacs with my own configuration.

    Anyway, thanks a lot for your time! :)

    Dear fellow emacsers.

    How can we make undo work on the scratch buffer? I'm sure it is a simple configuration issue, but I'm not getting the appropriate keyword to find the relevant documentation.

    Thanks a lot in advance for your help and attention... :) /\
