在Emacs中缓冲本地覆盖小模式键绑定 [英] Buffer-locally overriding minor-mode key bindings in Emacs

问题描述

我想使用一个重新绑定我绝对想要保留的主模式键的小模式。如何重新绑定密钥，而不是从全局的小模式地图中删除该密钥？我知道我可以使用 define-key ，但我想保留其他缓冲区/主要模式的绑定。

I want to use a minor mode which rebinds a major-mode key that I definitely want to keep. How can I rebind the key without deleting it from the minor-mode map globally? I know I can use define-key for that, but I would like to keep the binding for other buffers/major modes.

任何人都可以帮忙？

推荐答案

这样做有点麻烦。您可以执行以下操作：

It's a bit cumbersome to do. You can do something like:

(add-hook '<major-mode>-hook
  (lambda ()
    (let ((oldmap (cdr (assoc '<minor-mode> minor-mode-map-alist)))
          (newmap (make-sparse-keymap)))
      (set-keymap-parent newmap oldmap)
      (define-key newmap [<thekeyIwanttohide>] nil)
      (make-local-variable 'minor-mode-overriding-map-alist)
      (push `(<minor-mode> . ,newmap) minor-mode-overriding-map-alist))))
