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

问题描述

我想使用一个次要模式，它重新绑定一个我绝对想保留的主要模式键.如何重新绑定密钥而不将其从次要模式映射中全局删除?我知道我可以为此使用 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.

有人可以帮忙吗?

推荐答案

做起来有点麻烦.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))))
