emacs 中特定于文件的键绑定 [英] File-specific key-binding in emacs

问题描述

是否可以在 emacs 中定义特定于文件的键绑定?我想可以创建一个次要模式并在特定文件打开时加载它，但只有一个键绑定似乎有点矫枉过正.

Is it possible to define file specific key-bindings in emacs? I suppose it would be possible to create a minor mode and have it loaded when the particular file is open but for only one key-binding that seems overkill.

推荐答案

如果将代码组合到 local-set-key 和 在 Emacs 中缓冲本地覆盖次要模式键绑定 然后你可能会得到这样的结果:

If you combine the code to local-set-key and Buffer-locally overriding minor-mode key bindings in Emacs then you could end up with something like this:

(defun my-buffer-local-set-key (key command)
  (interactive "KSet key buffer-locally: 
CSet key %s buffer-locally to command: ")
  (let ((oldmap (current-local-map))
        (newmap (make-sparse-keymap)))
    (when oldmap
      (set-keymap-parent newmap oldmap))
    (define-key newmap key command)
    (use-local-map newmap)))

然后，根据 Barmar 的回答:

and then, as per Barmar's answer:

;; Local Variables:
;; eval: (my-buffer-local-set-key (kbd "C-c C-c") 'foo)
;; End:

请注意，次要模式地图优先于本地地图.

Note that minor mode maps take precedence over the local map.
