在Emacs的C/C++模式下#if 0 ... #endif塊內更改代碼顏色21.3.1

Question

參考鏈接， In C/C++ mode in Emacs, change face of code in #if 0...#endif block to comment face。

我試過了代碼，但它似乎沒有工作。我的emacs版本是Linux上的GNU Emacs 21.3.1。

請你讓我知道我要去哪裏錯了。

TIA

cpp-highlight-mode可製成無需用戶交互工作。這是我有我的設置：

(defun cpp-highlight-if-0/1() 
    "Modify the face of text in between #if 0 ... #endif." 
    (interactive) 
    (setq cpp-known-face '(background-color . "dim gray")) 
    (setq cpp-unknown-face 'default) 
    (setq cpp-face-type 'dark) 
    (setq cpp-known-writable 't) 
    (setq cpp-unknown-writable 't) 
    (setq cpp-edit-list 
     '((#("1" 0 1 
      (fontified nil)) 
      nil 
      (background-color . "dim gray") 
      both nil) 
      (#("0" 0 1 
      (fontified nil)) 
      (background-color . "dim gray") 
      nil 
      both nil))) 
    (cpp-highlight-buffer t)) 

(defun jpk/c-mode-hook() 
    (cpp-highlight-if-0/1) 
    (add-hook 'after-save-hook 'cpp-highlight-if-0/1 'append 'local) 
) 

(add-hook 'c-mode-common-hook 'jpk/c-mode-hook) 

的關鍵是搞清楚是cpp-highlight-mode看cpp-edit-list。我按照我想要的交互方式進行設置，然後查看，結果爲C-h v。
