Emacs评论/取消注释当前行 [英] Emacs comment/uncomment current line
问题描述
基本上,我想评论/取消当前行的注释。我期望这是一个非常容易的宏,但我发现它真的不是。
如果当前行被注释,取消注释。如果它被取消注释,评论。我也会评论整个行,而不仅仅是从光标位置。
我尝试过这样的宏:
Ca
'comment-dwim
但是,这只能评论一条线,而不是取消注释,如果它已经被评论。
我不知道它是多么容易,但如果有一些方式,我真的很喜欢。
另外,我喜欢这个想法的原因很多的是,当我使用Geany时,我只是使用了 Ce ,这是完美的。
尝试此功能,并绑定到您最喜欢的键:
(defun toggle-comment-on-line()
评论或取消注释当前行
(interactive)
(comment-or-uncomment-region(line-begin-position)(line-end-position)))
I know there's already an Emacs question on this, and that it was closed, but I find it quite relevant and important.
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.
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.
I tried a macro like this:
C-a
'comment-dwim
But this only work to comment a line, not to uncomment it, if it's already commented.
I'm not sure of how easy it is, but if there's some way, I'd really like it.
Also, the reason I love this idea so much is that when I used Geany, I just used C-e and it was perfect.
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)))
