To get a prompt which indicates Git-branch in Zsh


I run the following codes separately as my prompt unsuccessfully in .zshrc. This suggests me that apparently I do not have a program called __git_ps1. It is not in MacPorts.

#1

PROMPT="$(__git_ps1 " \[\033[1;32m\] (%s)\[\033[0m\]")\$"$

#2

PROMPT="$(__git_ps1 " (%s)")\$"$

#3

# Get the name of the branch we are on
git_prompt_info() {
  branch_prompt=$(__git_ps1)
  if [ -n "$branch_prompt" ]; then
    status_icon=$(git_status)
    echo $branch_prompt $status_icon
  fi
}

# Show character if changes are pending
git_status() {
  if current_git_status=$(git status | grep 'added to commit' 2> /dev/null); then
    echo "ā˜ "
  fi
}
autoload -U colors
colors
setopt prompt_subst
PROMPT='
%~%{$fg_bold[black]%}$(git_prompt_info)
ā†’ %{$reset_color%}'

How can you get a prompt which shows the name of a Git-branch?


Solution

  • __git_ps1 is from git-completion.bash. In zsh you probably have to provide your own function to determine the current directories git branch. There are quite a few blog posts about a git prompt for zsh.

    You just need:

    For example

    git_prompt() {
     ref=$(git symbolic-ref HEAD | cut -d'/' -f3)
     echo $ref
    }
    setopt prompt_subst
    PS1=$(git_prompt)%#
    autoload -U promptinit
    promptinit
    

    Update: use the zsh vcs_info module instead of git_prompt()

    setopt prompt_subst
    autoload -Uz vcs_info
    zstyle ':vcs_info:*' actionformats \
        '%F{5}(%f%s%F{5})%F{3}-%F{5}[%F{2}%b%F{3}|%F{1}%a%F{5}]%f '
    zstyle ':vcs_info:*' formats       \
        '%F{5}(%f%s%F{5})%F{3}-%F{5}[%F{2}%b%F{5}]%f '
    zstyle ':vcs_info:(sv[nk]|bzr):*' branchformat '%b%F{1}:%F{3}%r'
    
    zstyle ':vcs_info:*' enable git cvs svn
    
    # or use pre_cmd, see man zshcontrib
    vcs_info_wrapper() {
      vcs_info
      if [ -n "$vcs_info_msg_0_" ]; then
        echo "%{$fg[grey]%}${vcs_info_msg_0_}%{$reset_color%}$del"
      fi
    }
    RPROMPT=$'$(vcs_info_wrapper)'
