To get a prompt which indicates Git-branch in Zsh

问题:

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

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

回答1:

__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:

• a function to provide the branch name
• enable prompt (command) substitution
• add the function to your prompt

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)'

Here is an extended git prompt for zsh: zsh-git-prompt.

ko-dos's answer is great, but I prefer a slightly more git aware prompt than the one he uses. Specifically, I like staged, unstaged, and untracked file notifications in the prompt itself. Using his answer and the zsh vcs_info examples, I came up with the following:

setopt prompt_subst autoload -Uz vcs_info zstyle ':vcs_info:*' stagedstr 'M'  zstyle ':vcs_info:*' unstagedstr 'M'  zstyle ':vcs_info:*' check-for-changes true zstyle ':vcs_info:*' actionformats '%F{5}[%F{2}%b%F{3}|%F{1}%a%F{5}]%f ' zstyle ':vcs_info:*' formats \   '%F{5}[%F{2}%b%F{5}] %F{2}%c%F{3}%u%f' zstyle ':vcs_info:git*+set-message:*' hooks git-untracked zstyle ':vcs_info:*' enable git  +vi-git-untracked() {   if [[ $(git rev-parse --is-inside-work-tree 2> /dev/null) == 'true' ]] && \   [[ $(git ls-files --other --directory --exclude-standard | sed q | wc -l | tr -d ' ') == 1 ]] ; then   hook_com[unstaged]+='%F{1}??%f' fi }   precmd () { vcs_info } PROMPT='%F{5}[%F{2}%n%F{5}] %F{3}%3~ ${vcs_info_msg_0_} %f%# ' 

This creates a prompt that mimics the colorized output of git status -s (which can be configured in your .gitconfig file). A picture is perhaps most helpful here:

Compared with git status -s:

If you don't like colorized output, or would prefer some other character or prompt construction, just change the stagedstr, unstagedstr, and hook_com[unstaged] values in the above code.

Thank you for the links!

I made the following prompt based on them

     # get the name of the branch we are on      git_prompt_info() {           git branch | awk '/^\*/ { print $2 }'      }      get_git_dirty() {         git diff --quiet || echo '*'      }       autoload -U colors      colors           setopt prompt_subst       PROMPT='%{$fg[blue]%}%c %{$fg_bold[red]%}$(git_prompt_info)$(get_git_dirty)%{$fg[blue]%} $ %{$reset_color%}'                                                  RPROMPT='%{$fg[green]%}%1(j.%j.)'         

Please, suggest any improvements.
