Thanks a lot. But did you mean last-prefix-arg instead? I want the
prefix arg that was passed to last-command. After your hint, I read
(info "(elisp) Prefix Command Arguments").
This is pseudo-code for what I'm trying to do:
(defun my-cmd-1 (&optional args) nil)
(defun my-cmd-2 (&optional args)
(if (eq last-command 'my-cmd-1)
(progn
(setq this-command 'my-cmd-1)
(my-cmd-1 last-prefix-arg)
(setq prefix-arg last-prefix-arg)) ;; <-- this bit doesn't seem to work
(some-command arg)))
Then I call my-cmd-1, now if I call my-cmd-2 right after, it repeats
my-cmd-1. If I do something else in between, the my-cmd-2 just calls
some-command.
I hope my intentions are clearer now.
