vi的dd的emacs等价物是什么?我想删除当前行。试过 CTRL + k 但它只从当前位置删除。
C-a # Go to beginning of line
C-k # Kill line from current point
还有
C-S-backspace # Ctrl-Shift-Backspace
它调用 M-x kill-whole-line
。
如果你想设置一个不同的全局键绑定,你可以把它放在 ~/.emacs 中:
(global-set-key "\C-cd" 'kill-whole-line) # Sets `C-c d` to `M-x kill-whole-line`
如果要删除多个整行,可以在命令前加上一个数字:
C-u 5 C-S-backspace # deletes 5 whole lines
M-5 C-S-backspace # deletes 5 whole lines
C-u C-S-backspace # delete 4 whole lines. C-u without a number defaults to 4
C-u -5 C-S-backspace # deletes previous 5 whole lines
M--5 C-S-backspace # deletes previous 5 whole lines
有时我也发现 C-x z
有帮助:
C-S-backspace # delete 1 whole line
C-x z # repeat last command
z # repeat last command again.
# Press z as many times as you wish.
# Any other key acts normally, and ends the repeat command.
如果您不想终止该行(这会将其放入操作系统剪贴板并终止环),而只需将其删除:
(defun delete-current-line ()
"Delete (not kill) the current line."
(interactive)
(save-excursion
(delete-region
(progn (forward-visible-line 0) (point))
(progn (forward-visible-line 1) (point)))))
另一种删除线而不将其放入杀伤环的方法:
(defun delete-current-line ()
"Deletes the current line"
(interactive)
(delete-region
(line-beginning-position)
(line-end-position)))
这将使该点位于空白行的开头。为了摆脱这种情况,您可能希望在函数末尾添加类似 (delete-blank-lines)
的内容,如本例所示,这可能不太直观:
(defun delete-current-line ()
"Deletes the current line"
(interactive)
(forward-line 0)
(delete-char (- (line-end-position) (point)))
(delete-blank-lines))
而不是使用单独的键来删除行,或者必须调用前缀参数。您可以使用 crux-smart-kill-line 它将“杀死到行尾并在下一次调用时杀死整行”。但是,如果您更喜欢 delete
而不是 kill
,则可以使用下面的代码。
对于点到字符串操作(杀死/删除),我建议使用 zop-to-char
(defun aza-delete-line ()
"Delete from current position to end of line without pushing to `kill-ring'."
(interactive)
(delete-region (point) (line-end-position)))
(defun aza-delete-whole-line ()
"Delete whole line without pushing to kill-ring."
(interactive)
(delete-region (line-beginning-position) (line-end-position)))
(defun crux-smart-delete-line ()
"Kill to the end of the line and kill whole line on the next call."
(interactive)
(let ((orig-point (point)))
(move-end-of-line 1)
(if (= orig-point (point))
(aza-delete-whole-line)
(goto-char orig-point)
(aza-delete-line))))
从线上的任何点删除(杀死)整行而不选择任何内容的最快/最简单的方法是:
C-w ; kill-region
它在删除任何选择的内容时非常通用,或者如果未选择任何内容,则默认删除一行。
鉴于这个问题,您可能还对复制 Vim 的“yank”yy
感兴趣(尽管在 Emacs 中,“yank”与 Vim 的“put”p
混淆)。这是:
M-w ; kill-ring-save
很好,一致,而且很容易记住。甚至有点类似于 Vim 的 i_CTRL-W
。
一旦您使用上述任何一种方法将某些东西放入杀伤环中,您可能会想要“拉动”(粘贴)它:
M-y ; yank-pop
(请注意,CS-backspace 可能在终端 Emacs 中不起作用。)
安装软件包 whole-line-or-region
,然后运行 (whole-line-or-region-global-mode)
。如果没有区域(选择)处于活动状态,这将使 C-w
杀死整行。

C-x z
,这真的很酷。顺便说一句,答案很好且准确。C-k C-k
,它有点像 vim 中的d$ S-j
,但这可以很好地删除向前的行。C-cd
中没有空格?
