I want to simplify repeated calls in my init.el file

Question

I've got a lot of:

(desktop-save-mode 1)
(show-paren-mode 1)

which I'd like to collapse into:

(mapcar (lambda (fn) (fn 1)) '(desktop-save-mode show-paren-mode))

but I get an error:

Symbol’s function definition is void: fn

How can I call a list of functions with the same argument?

You don't need to pass `1` to enable a minor mode, so `(mapc #'funcall '(...))` will do the trick. — Stefan, Nov 21 '19 at 20:30
I'm certain this is a duplicate (for learning about `funcall` and friends), but I seem to be failing at searching. Refer to `C-h i g (elisp)Calling Functions` for the details. — phils, Nov 22 '19 at 01:07

desktop-save-mode

is defined thusly:

(define-minor-mode desktop-save-mode

so its not a function...

I'd still like to clean up my init file, any suggestions on how I could do that? – ftravers Nov 21 '19 at 18:41

Hmm... `define-minor-mode` defines a function (and a variable as well), so yes it *is* a function. – Stefan Nov 21 '19 at 20:27
