prompt 설정

이렇게 깔끔하게 바꾸고싶다.

prompt clean

prompt not clean

zsh

아래 shell script를 .zshrc에 추가

function parse_git_branch() {
    git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/(\1) /p'
}

COLOR_RED=160
COLOR_ORANGE=172
COLOR_SKY=039
COLOR_GREEN=041
COLOR_GREY=008
COLOR_PUPPLE=099

function branch_color() {
    local git_status="$(git status 2> /dev/null)"

    if [[ $git_status =~ "Untracked files" ]]; then
      echo -e $COLOR_GREY
    elif [[ $git_status =~ "Changes not staged for commit" ]]; then
      echo -e $COLOR_RED
    elif [[ $git_status =~ "Changes to be committed" ]]; then
      echo -e $COLOR_ORANGE
    elif [[ $git_status =~ "Your branch is ahead of" ]]; then
      echo -e $COLOR_PUPPLE
    else
      echo -e $COLOR_GREEN
    fi
}

setopt PROMPT_SUBST
export PROMPT='%F{$COLOR_SKY}%~ %F{$(branch_color)}$(parse_git_branch)%F{$COLOR_SKY}$ %f'

%n $USERNAME.
%~ Current working directory, but if the current working directory starts with $HOME, that part is replaced by a ‘~’.
%F (%f) Start (stop) using a different foreground color.
- e.g. ‘%F{cyan}..%f’ or ‘%F{0-255}..%f’
%K (%k) Start (stop) using a different background color. The syntax is identical to that for %F and %f.
- e.g. ‘%K{cyan}..%k’ or ‘%K{0-255}..%k’
%B (%b) Start (stop) boldface mode.
