如何在emacs上通过"Mx customize"设置变量注释？

Question

当我设置变量时M-x customize,值将存储在我的.emacs文件中这个自动生成的按字母排序的大型列表中.

问题是我想记录为什么我选择特定值而不是特定变量的默认值.如果我通过在自动生成的列表中添加elisp注释来实现这一点,那么下次我自定义另一个变量时它们就会被破坏.

有没有办法Custom保持我的评论,还是有其他标准的方法来注释这个？

Answer 1

就个人而言,我将所有设置从自定义中移出到我的.emacs文件中.主要是因为我真的不喜欢自定义UI.

所以,而不是这是我的自定义文件:

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(scheme-program-name "scheme")
 '(tetris-use-glyphs nil))

我有:

 (setq
  scheme-program-name "scheme"      ; because I like it
  tetris-use-glyphs nil)            ; it's an example

也就是说,custom-set-variable确实需要一些参数,其中一个是注释.所以你可以这样做:

(custom-set-variables
  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.
  ;; Your init file should contain only one such instance.
  ;; If there is more than one, they won't work right.
 '(scheme-program-name "scheme" nil nil "this is a comment")
 '(tetris-use-glyphs nil nil nil "This is another comment"))

只有当您更改变量的值时,注释才会被吹走,而不是在您更改其他变量时.我不确定这是否适用于此. C-h f custom-set-variables有更多信息.
