Emacs: Toggle Comment Current Line 🚀
Here's a command to toggle comment of current line.
put this in your Emacs Init File:
(defun xah-comment-dwim () "Like `comment-dwim', but toggle comment if cursor is not at end of line. URL `http://xahlee.info/emacs/emacs/emacs_toggle_comment_by_line.html' Version 2016-10-25" (interactive) (if (region-active-p) (comment-dwim nil) (let (($lbp (line-beginning-position)) ($lep (line-end-position))) (if (eq $lbp $lep) (progn (comment-dwim nil)) (if (eq (point) $lep) (progn (comment-dwim nil)) (progn (comment-or-uncomment-region $lbp $lep) (forward-line )))))))
Put it in your emacs init.
Also, you can give it the comment-dwim key, like this:
(global-set-key (kbd "M-;") 'xah-comment-dwim)
