I am trying to stop emacs from expanding abbrevs after I press the return key. If I press return, I simply want to create a new line without expanding any abbrev at point.

I am relatively new at elisp. I’m assuming the answer involves pre-abbrev-expand-hook, but I haven’t found an answer in my research.

  • That's fine, no need to do anything further @Faulkner77. This question will probably end up getting closed, since it already has an answer in the linked post. That doesn't mean there's anything wrong here, just that we want to keep the site streamlined, with a single question/answer post for each issue.

It seems this has been addressed after all in similar post here that I found after the fact. The solution I settled on was as follows:

(defun my-self-insert-no-abbrev-RET ()
  (let ((abbrev-mode nil))
    (newline nil t)))

(global-set-key (kbd "RET") #'my-self-insert-no-abbrev-RET)
