Emacs光标移动建议

Question

我已经编写了一个次要模式，当光标在缓冲区中移动时，它会突出显示缓冲区的各个部分。我通过建议如下的移动函数来做到这一点。

...
(defadvice next-line (after showcss/advise-main)
  "Advice around cursor movement"
  (highlight-some-stuff))
(defadvice previous-line (after showcss/advise-main)
  "Advice around cursor movement"
  (highlight-some-stuff))
(defadvice right-char (after showcss/advise-main)
  "Advice around cursor movement"
  (highlight-some-stuff))
(defadvice left-char (after showcss/advise-main)
  "Advice around cursor movement"
  (highlight-some-stuff))
(defadvice forward-word (after showcss/advise-main)
  "Advice around cursor movement"
  (highlight-some-stuff))
(defadvice backward-word (after showcss/advise-main)
  "Advice around cursor movement"
  (highlight-some-stuff))
...

但这似乎是错误的做法。我一直在寻找一个用于光标移动的钩子，但似乎没有。

我是不是缺少了一个可以用来代替建议一大堆移动函数的钩子，或者有没有更好的方法来解决这个问题？

嗯..。几天前，我给你发了一封电子邮件，建议在GNU ELPA中包含showcss，其中我还建议你使用post-command-hook而不是那些防御建议。
