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

问题描述

当使用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杀戒中。这可能会令人讨厌，因为我正在移动到另一个文件来粘贴某些东西，我最终粘贴文件路径的一部分。我知道有解决方法，其他代码仍然在杀死戒指等等，但我只是想禁用这个功能。

解决方案

Emacs没有向后删除字词功能，但是很容易定义一个：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ b many many many many many many many many many many。。。。。。。。。
（interactivep）
（delete-region（point）（progn（backward-word arg）（point））））
/ pre>

然后，您可以将中的M-Backspace绑定到 back-delete-word minibuffer-local-map ：

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

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.

解决方案

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))))

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

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