How do I get Emacs to evaluate a file when a frame is raised?

Question

Basically I have my Emacs set up so it has a GUI specific elisp, but when starting it in daemon mode this doesn't evaluate. The code is something like:

;; gui.el
(when window-system
  (progn
    ;; do stuff here
    ))

I'd like this file (or at least the code within it—perhaps a funtion) to be re-evaluated when I run emacsclient -c on the command line, as I miss out on all my font-lock and color-theme goodness (as I have that stuff set to runonly when a GUI exists).

Answer 1

You should evaluate your GUI function when starting emacsclient:

emacsclient -c --eval "(your-gui-init-function)"

Answer 2

You can put your code in a hook to be called before a frame is created

(add-hook 'before-make-frame-hook 'my-gui-initialization-stuff)

In that hook you probably want to have a line that does

(remove-hook 'before-make-frame-hook 'my-gui-initialization-stuff)

so you don't do the initialization over and over.
