Ignore save if buffer isn't visiting a file

Cool idea, nice solution, not-so-good Lisp. (defun my/save-buffer (&optional arg) "Like `save-buffer', but does nothing if buffer is not visiting a file." (interactive "p") (unless (buffer-file-name) (user-error "Use 'M-x save-buffer' explicitly to save this buffer with no visited file")) (save-buffer arg)) FTFY

Thanks Phil-Hudson! I have updated the elisp with your suggestion!
