awesome-tray module-add-to-alist

(defun kiteab/awesome-tray-emacs-info ()
  (concat "KiteAB Emacs"))
(add-to-list 'awesome-tray-module-alist '("emacs" . (kiteab/awesome-tray-emacs-info awesome-tray-module-battery-face)))

我想改写成

(defun kiteab/awesome-tray-emacs-info ()
  (concat "KiteAB Emacs"))
(awesome-tray-add-module-to-alist "emacs" #'kiteab/awesome-tray-emacs-info awesome-tray-module-battery-face)

其中face是可选值 有什么比较好的方案吗:laughing:
