在 emacs 中以不同的颜色显示数字

我想在任何模式下，将数字的颜色与文本字符的颜色不同。我该如何修改 .emacs 文件以实现此目的？我希望我的数字始终显示为粉红色。

Gvim 似乎已经内置了此功能。

用法——激活或停用本地和：   M-x smilingbuddha-mode

启用smilingbuddha-mode 全球，取消注释(global-smilingbuddha-mode)并重新启动；或者，输入M-x global-smilingbuddha-mode（该命令将一直有效，直到您重新启动）。

请随意修改正则表达式以满足您的个人需要。

(define-minor-mode smilingbuddha-mode
  "Minor mode for highlighting numbers."
  :group 'smilingbuddha
  :lighter " :)"
  (cond
    (smilingbuddha-mode
      (when (not (or font-lock-mode global-font-lock-mode))
        (font-lock-mode 1))
      (font-lock-add-keywords nil
        (list (list "\\([0-9]+\\)" '(0 'smilingbuddha-pink-face t)) ))
      (message "Turned ON `smilingbuddha-mode`."))
    ((not smilingbuddha-mode)
      (font-lock-remove-keywords nil
        (list (list "\\([0-9]+\\)" '(0 'smilingbuddha-pink-face t)) ))
      (font-lock-fontify-buffer)
      (message "Turned OFF `smilingbuddha-mode`."))))

(defgroup smilingbuddha nil
  "Highlight numbers."
  :version "0.1"
  :group 'smilingbuddha)

(defface smilingbuddha-pink-face
  '((t (:foreground "black" :background "pink")))
  "Face for `smilingbuddha-pink-face`."
  :group 'smilingbuddha)

(defun turn-on-smilingbuddha-mode ()
(interactive)
  (smilingbuddha-mode 1))

(defun turn-off-smilingbuddha-mode ()
(interactive)
  (smilingbuddha-mode -1))

(define-globalized-minor-mode global-smilingbuddha-mode
  smilingbuddha-mode turn-on-smilingbuddha-mode)
;; (global-smilingbuddha-mode)
