在emacs中的文件特定键绑定 [英] File-specific key-binding in emacs

问题描述

是否可以在emacs中定义文件特定的键绑定？
我想可以创建一个次模式，并在特定文件打开时加载，但只有一个密钥绑定似乎过度杀伤。

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 和缓冲区本地覆盖Emacs中的次模式密钥绑定，那么你可能会得到如下结果：

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: \nCSet 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)))

然后按照Barmar的答案：

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，小模式地图优先于本地地图。

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