Hi,
I created the function at [1] a while ago and bound it to C-x t i, and
it has been working fine. Now when I press C-x t i, I'm getting
Debugger entered--Lisp error: (wrong-number-of-arguments #<subr my-perltidy-replace> 1)
my-perltidy-replace(nil)
funcall-interactively(my-perltidy-replace nil)
command-execute(my-perltidy-replace)
What might have changed is the emacs version because I built one that
uses wayland, but I don't remember if it used to work with the wayland
version.
I'm guessing that emacs now figures that the function is getting an
argument where it doesn't take one, and I fail to make sense of
this. How can I fix this?
[1]:
(defun my-perltidy-replace ()
"This function replaces the contents of the current buffer with
the output of perltidy, and makes a backup of the current buffer.
The backup is then saved."
(interactive "P")
(let ((tidy_buffer (generate-new-buffer (generate-new-buffer-name (concat "TidyBackup-" (buffer-name))))))
(with-current-buffer (buffer-name)
(shell-command-on-region (point-min) (point-max) "perltidy --standard-output" tidy_buffer)
(buffer-swap-text tidy_buffer))
(with-current-buffer tidy_buffer
(let ((visiting_file (generate-new-buffer-name (concat "~/tmp/TidyBackup/" (buffer-name)))))
(set-visited-file-name visiting_file)
(save-buffer)
(message "backup saved as %s" visiting_file)))))

Change the line `(interactive "P")' to `(interactive")'. I don't see
how it could have worked before, since `(interactive "P")' means the
command can be called with a raw prefix argument, so it would have to be
defined e.g. like this: (defun my-perltidy-replace (&optional arg)...
