Have done this function, but cannot get imenu to run and show the function names
It seems to require arguments, but I do not know what has to be done.

(defun vodil-imenu-function-list ()
  "Set up `imenu` to show a list of functions in the current buffer."

  (interactive)
  (setq imenu-generic-expression
         '((nil "^(defun\\s-+\\([^ \t\n]+\\)" 1)))
  (imenu-add-to-menubar "Function List")
  (imenu))
