Emacs 注释/取消注释当前行 [英] Emacs comment/uncomment current line

问题描述

我知道 Emacs 上已经有一个关于此的问题，并且已经关闭，但我发现它非常相关且重要.

I know there's already an Emacs question on this, and that it was closed, but I find it quite relevant and important.

基本上，我想注释/取消注释当前行.我原以为使用宏会很容易做到这一点，但我发现事实并非如此.

Basically, I want to comment/uncomment the current line. I was expecting this to be fairly easy with a macro, but I found that it really isn't.

如果当前行被注释，则取消注释.如果未注释，请对其进行注释.而且我还想注释掉整行，而不仅仅是从光标位置.

If the current line is commented, uncomment. If it is uncommented, comment it. And I would also to comment out the whole line, not just from cursor position.

我试过这样的宏:

C-a

'comment-dwim

但这只适用于注释一行，而不是取消注释，如果它已经被注释了.

But this only work to comment a line, not to uncomment it, if it's already commented.

我不确定这有多容易，但如果有办法，我真的很喜欢.

I'm not sure of how easy it is, but if there's some way, I'd really like it.

另外，我非常喜欢这个想法的原因是，当我使用 Geany 时，我只使用了 C-e，它非常完美.

Also, the reason I love this idea so much is that when I used Geany, I just used C-e and it was perfect.

推荐答案

试试这个功能，绑定你最喜欢的键:

Try this function, and bind to your favorite key:

(defun toggle-comment-on-line ()
  "comment or uncomment current line"
  (interactive)
  (comment-or-uncomment-region (line-beginning-position) (line-end-position)))
