Emacs after-make-frame-functions argument is void

I have the following code in my .emacs file. It's supposed to move the input focus to any newly created frame.

(defun foo-focus-new-frame (frame)
  (select-frame-set-input-focus (frame)))
(add-hook 'after-make-frame-functions 'foo-focus-new-frame t)

This works fine when I run emacs directly from the command line. However, if emacs is not started and I try and run the following:

emacsclient -c -a '' test.txt

I get the following error:

*ERROR*: Symbol's function definition is void: frame

Why is this? According to the documentation the after-make-frame-functions hook should only be run after a frame is newly created, so why can't my function find it?

Solution

  • The frame function doesn't exist, perhaps you intended to access the parameter instead of calling a function, i.e. you have extraneous parentheses in foo-focus-new-frame:

    (defun foo-focus-new-frame (frame)
  (select-frame-set-input-focus frame))
