I have some elisp code in my ~/.emacs which sets a variable for the default font:

(let ((myfont "Ubuntu Mono-13"))
  (unless (member myfont (font-family-list))
    (setq myfont "DejaVu Sans Mono-13"))
  (add-to-list 'default-frame-list '(font . myfont))
  (set-face-attribute 'default nil :font myfont))

however I'm having a hard time constructing the string which is the last parameter of the call to (add-to-list) such that the variable 'myfont' is evaluated. Instead of:

'(font . myfont)

I would like to send:

'(font . "Ubuntu Mono-13")

'(font . "DejaVu Sans Mono-13")

I've tried various things with (car), (cdr), and (concat) to no avail.

Have a look at How to evaluate the variables before adding them to a list?. For your specific case, you want to use \(font . ,myfont)in your config rather than'(font . myfont)`. – Dan Jul 31 '15 at 19:24

or (cons 'font myfont) – Jordon Biondo Jul 31 '15 at 19:27
