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
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$
