git status in the prompt -

Working with git a lot I decided I needed some git status in my prompt.

I searched the web and some solutions where almost what I wanted and this one by Sebastian Celis came very close.

But it didn’t work with my version of zsh, because that didn’t seem to understand the =~ operator.

I also think Sebastian makes things over complicated and so I changed some things aroud.

This is what I came up with:

First make sure this code is included in your ~/.zshenv file _~ \{.zsh} prompt_git_info() \{ unset GIT_BRANCH unset GIT_BRANCH_STATUS unset __GIT_BRANCH_DIRTY

local st="$(git status 2>/dev/null)"
if [[ -n "$st" ]]; then
    local -a arr
    arr=(${(f)st})

    if [[ $arr[1] = *Not\ currently\ on\ any\ branch.* ]]
    then
        __GIT_BRANCH='no-branch'
    else
        __GIT_BRANCH="${arr[1][(w)4]}"
    fi

    if [[ $arr[2] = *Your\ branch\ is* ]]
    then
        if [[ $arr[2] = *ahead* ]]
        then
            __GIT_BRANCH_STATUS='ahead'
        elif [[ $arr[2] = *diverged* ]]
        then
            __GIT_BRANCH_STATUS='diverged'
        else
            __GIT_BRANCH_STATUS='behind'
        fi
    fi

    if [[ $st = *nothing\ to\ commit* ]]
    then
        __GIT_BRANCH_DIRTY='0'
    else
        __GIT_BRANCH_DIRTY='1'
    fi
fi

if [[ -n "$__GIT_BRANCH" ]]
then
    local s="("
    s+="$__GIT_BRANCH"
    case "$__GIT_BRANCH_STATUS"
    in
        ahead)      s+="↑"  ;;
        diverged)   s+="↕"  ;;
        behind)     s+="↓"  ;;
    esac
    if [[ "$__GIT_BRANCH_DIRTY" = "1" ]]
    then
        s+="⚡"
    fi
    s+=")"

    printf " %s%s" "%{${fg[yellow]}%}" $s
fi

} _~

and set your prompt to something like this

PS1=$'$C_CYAN%n@%m$(prompt_git_info) $C_WHITE%2~$ $C_OFF'

When I now switch to a directory that is under control of git I get gt status messages in my prompt, like

tonk@mach (master⚡) ~/dir$ git commit -a
[master fca5ac3] Nice, new stuff.
 6 files changed, 88 insertions(+), 12 deletions(-)
tonk@mach (master↑) ~/.dir$ git status
# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
nothing to commit (working directory clean)
tonk@mach (master↑) ~/.dir$
