基础函数来源stackoverflow
(defun comment-or-uncomment-region-or-line ()
"Comments or uncomments the region or the current line if there's no active region."
(interactive)
(let (beg end)
(if (region-active-p)
(setq beg (region-beginning) end (region-end))
(setq beg (line-beginning-position) end (line-end-position)))
(comment-or-uncomment-region beg end)))
现在我想要修改,当前行如果有折叠则先选择当前行,然后注释
(defun comment-or-uncomment-region-or-line ()
"Comments or uncomments the region or the current line if there's no active region."
(interactive)
(when (hs-already-hidden-p)
(evil-visual-line))
(let (beg end)
(if (region-active-p)
(setq beg (region-beginning) end (region-end))
(setq beg (line-beginning-position) end (line-end-position)))
(comment-or-uncomment-region beg end)))
但一直得不到想要的效果,折叠使用的是hideshow,有人知道该怎么写吗？另外evil-visual-line能否转成emacs自带的函数
不是很理解什么叫选择当前行，再注释，选择了怎么注释。。。可能和你的需求不太一样
这是选择当前行, 其实我觉得在Emacs里的选择并不好，因为势必会改变光标位置
(defun comment-or-uncomment-region-or-line ()
"Comments or uncomments the region or the current line if there's no active region."
(interactive)
(let ((p (point)))
(forward-line 0)
(if (hs-already-hidden-p) (progn (hs-toggle-hiding) (set-mark (point)) (end-of-line))
(let ((b (if (region-active-p) (region-beginning) (line-beginning-position)))
(e (if (region-active-p) (region-end) (line-end-position))))
(goto-char p) (comment-or-uncomment-region b e)))))
这是要注释
(defun comment-or-uncomment-region-or-line ()
"Comments or uncomments the region or the current line if there's no active region."
(interactive)
(save-excursion
(forward-line 0)
(when (hs-already-hidden-p) (hs-toggle-hiding)))
(let ((b (if (region-active-p) (region-beginning) (line-beginning-position)))
(e (if (region-active-p) (region-end) (line-end-position))))
(comment-or-uncomment-region b e)))
因为这里有一个折叠，如果是按照原来的方式，只会注释第一行，而不会将整个折叠都注释了
我试过，如果先选中整行 evil-visual-line,那么就会把整个折叠当做一个代码块来注释
自己实现了一个
(defun comment-or-uncomment-region-or-line ()
"Comments or uncomments the region or the current line if there's no active region."
(interactive)
(when (hs-already-hidden-p)
(end-of-visual-line)
(evil-visual-state)
(beginning-of-visual-line))
(let (beg end)
(if (region-active-p)
(setq beg (region-beginning) end (region-end))
(setq beg (line-beginning-position) end (line-end-position)))
(comment-or-uncomment-region beg end)))
我也写了一个，我不用Evil的。。。
(defun comment-or-uncomment-region-or-line ()
"Comments or uncomments the region or the current line if there's no active region."
(interactive)
(save-excursion
(forward-line 0)
(when (hs-already-hidden-p)
(put 'comment-or-uncomment-region-or-line 'zzz t)
(goto-char (hs-find-block-beginning))
(set-mark (point))
(forward-sexp 1))
(let ((b (if (region-active-p) (region-beginning) (line-beginning-position)))
(e (if (region-active-p) (region-end) (line-end-position))))
(comment-or-uncomment-region b e)
(when (get 'comment-or-uncomment-region-or-line 'zzz)
(put 'comment-or-uncomment-region-or-line 'zzz nil)
(hs-toggle-hiding)(hs-toggle-hiding)))))
