zsh vi mode status line
提问by ui_90jax
Is there a way in zsh or bash to have a status line? e.g. in VI it will let you know that you are in insert mode with -- INSERT --
zsh 或 bash 有没有办法设置状态行？例如，在 VI 中，它会通过 -- INSERT -- 让您知道您处于插入模式
Is there an eqivalent for the command line?
命令行是否有等价物？

This has already been answered at Super Userand Unix Stack Exchange. For the completeness of Stack Overflow:
这已经在Super User和Unix Stack Exchange 上得到了回答。为了 Stack Overflow 的完整性：
function zle-line-init zle-keymap-select {
RPS1="${${KEYMAP/vicmd/-- NORMAL --}/(main|viins)/-- INSERT --}"
RPS2=$RPS1
zle reset-prompt
}
zle -N zle-line-init
zle -N zle-keymap-select
And if you want the indicator below the current line rather than to the right, from Unix Stack Exchange:
如果您希望指示器位于当前行下方而不是右侧，则来自Unix Stack Exchange：
terminfo_down_sc=$terminfo[cud1]$terminfo[cuu1]$terminfo[sc]$terminfo[cud1]
function zle-line-init zle-keymap-select {
PS1_2="${${KEYMAP/vicmd/-- NORMAL --}/(main|viins)/-- INSERT --}"
PS1="%{$terminfo_down_sc$PS1_2$terminfo[rc]%}%~ %# "
zle reset-prompt
}
preexec () { print -rn -- $terminfo[el]; }
