[英]The way to distinguish command-mode and insert-mode in Bash's Vi command line editing
I'm always little bit confused when bash in vi-mode is switched to insert-mode, because it doesn't give any tip about used mode (command or edit). 当vi模式下的bash切换到插入模式时,我总是有点困惑,因为它没有提供有关使用模式(命令或编辑)的任何提示。 Is there any way to distinguish mods? 有什么办法可以区分MOD吗? May be automatic change of cursor color or something like that? 可能是自动更改光标颜色或类似的东西?
in /etc/inputrc (or ~/.inputrc) add this: 在/ etc / inputrc(或〜/ .inputrc)中添加以下内容:
set show-mode-in-prompt on
this will prefix your prompt with + while in insert-mode, and : while in command mode in bash 4.3 在bash 4.3中,在插入模式下,这会在提示符前加上+ ;在命令模式下,则是::
EDIT: in the latest version of bash 4.4, you will instead get a prompt prefixed with "(ins)" or "(cmd)" by default. 编辑:在最新版本的bash 4.4中,默认情况下,您将得到一个前缀为“(ins)”或“(cmd)”的提示。 but, you can change that: 但是,您可以更改以下内容:
set vi-ins-mode-string "+"
set vi-cmd-mode-string ":"
also, you can use color codes like '\\e[1;31m', but surround them with '\\1' and '\\2' to keep readline happy: 同样,您可以使用颜色代码,例如'\\ e [1; 31m“,但将它们用'\\ 1'和'\\ 2'包围,以使readline保持高兴:
set vi-cmd-mode-string "\1\e[1;31m\2:\1\e[0m\2"
Building on @Isaac Hanson's answer you can set the cursor style to reflect the mode (just like in VIM) by setting these in your .inputrc
: 在@Isaac Hanson的答案的基础上,您可以通过在.inputrc
进行设置来设置光标样式以反映模式(就像在VIM中一样):
set editing-mode vi
set show-mode-in-prompt on
set vi-ins-mode-string \1\e[6 q\2
set vi-cmd-mode-string \1\e[2 q\2
# optionally:
# switch to block cursor before executing a command
set keymap vi-insert
RETURN: "\e\n"
This will give you a beam cursor in insert mode or a block cursor for normal mode. 这将为您提供插入模式下的光束光标或正常模式下的块光标。
Other options (replace the number after \\e[
): 其他选项(将数字替换为\\e[
):
Ps = 0 -> blinking block.
Ps = 1 -> blinking block (default).
Ps = 2 -> steady block.
Ps = 3 -> blinking underline.
Ps = 4 -> steady underline.
Ps = 5 -> blinking bar (xterm).
Ps = 6 -> steady bar (xterm).
Your terminal must support DECSCURSR (like xterm, urxvt, iTerm2). 您的终端必须支持DECSCURSR(例如xterm,urxvt,iTerm2)。 TMUX also supports these (if you set TERM=xterm-256color
outside tmux). TMUX也支持这些(如果在tmux外部设置TERM=xterm-256color
)。
After years of using vi mode in korn shell, I have basically trained myself to just tap ESC
a few times before I type any commands, and ESC
then i
to start typing. 经过多年在Korn shell中使用vi模式,我已经基本训练自己只需轻按ESC
前几次我输入任何命令, ESC
然后i
开始打字。
The basic premise being that if you just hit ESC
, you know precisely what mode you are in. 基本前提是,如果您只是按ESC
,那么您将确切知道所处的模式。
