删除一个单词而不将其添加到 Emacs 中的 kill-ring [英] Delete a word without adding it to the kill-ring in Emacs

问题描述

在使用 minibuffer (C-x C-f) 切换文件时，我经常使用 M-Backspace 删除路径中的单词.Emacs 会自动将我删除的内容放入 kill ring.这可能很烦人，因为有时我要移动到另一个文件来粘贴某些内容，而我最终会粘贴文件路径的一部分.我知道有一些变通方法，其他代码仍在终止环等中，但我只想禁用此功能.

When switching files using the minibuffer (C-x C-f), I often use M-Backspace to delete words in the path. Emacs automatically places what I delete into the kill ring. This can be annoying, as sometime I am moving to another file to paste something, and I end up pasting part of the file path. I know there are workarounds, and the other code is still in the kill ring, etc, but I would just like to disable this functionality.

推荐答案

Emacs 没有 backward-delete-word 功能，但定义一个很容易:

Emacs doesn't have a backward-delete-word function, but it's easy enough to define one:

(defun backward-delete-word (arg)
  "Delete characters backward until encountering the beginning of a word.
With argument ARG, do this that many times."
  (interactive "p")
  (delete-region (point) (progn (backward-word arg) (point))))

然后就可以在minibuffer-local-map中将M-Backspace绑定到backward-delete-word:

Then you can bind M-Backspace to backward-delete-word in minibuffer-local-map:

(define-key minibuffer-local-map [M-backspace] 'backward-delete-word)
