zsh change prompt input color
提问by Sherwin Yu
I want to change the color of the input text in zsh (the text that I type for each command). Example: in user@host> ls ~/I would want ls ~/to be yellow to stand out from standard output.
我想更改 zsh 中输入文本的颜色（我为每个命令键入的文本）。示例：在user@host> ls ~/我想要ls ~/黄色以从标准输出中脱颖而出。
I know I can accomplish this in bashusing
我知道我可以在bash 中使用
export PS1=" $BIGreen \u@\h \w $ $IYellow"
At the end of the prompt, the color is set to Yellow, input text I type is yellow (with the appropriate color variables defined). And then
在提示结束时，颜色设置为黄色，我输入的输入文本为黄色（定义了适当的颜色变量）。进而
trap 'echo -ne "\e[0m"' DEBUG
Which resets the color to normal when the outputs of my command are displayed.
当显示我的命令的输出时，它将颜色重置为正常。
How can I accomplish this in zsh? Currently, I have
我怎样才能在zsh 中做到这一点？目前，我有
PROMPT=$'{$fg[green]%}%n@%{$fg[green]%}%m %# %{$fg[yellow]%}'
in .zshrc (setting color to yellow at the end) but it does not work. (I also wouldn't know how to set the color back to white after the command).
在 .zshrc 中（最后将颜色设置为黄色）但它不起作用。（我也不知道如何在命令后将颜色设置回白色）。

Try this:
尝试这个：
PROMPT="%F{green}%n@%m %# %F{yellow}"
preexec () { echo -ne "\e[0m" }
I tried using trap, but it looks like DEBUGdoesn't happen until after the command runs/before the next prompt, so the command ends up executing in yellow. The preexec()function gets called before the command executes, so you can restore the default color there.
我尝试使用trap，但看起来DEBUG直到命令运行之后/下一个提示之前才会发生，因此该命令最终以黄色执行。该preexec()函数在命令执行之前被调用，因此您可以在那里恢复默认颜色。
