zsh change prompt input color

问题

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.

I know I can accomplish this in bash using

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

trap 'echo -ne "\e[0m"' DEBUG

Which resets the color to normal when the outputs of my command are displayed.

How can I accomplish this in zsh? Currently, I have

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).

回答1:

Try this:

PROMPT="%F{green}%n@%m %# %F{yellow}"
preexec () { echo -ne "\e[0m" }

I tried using trap, but it looks like DEBUG doesn'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.
