Minimalist git prompt

For as long as I can remember, I have had some sort of git status as part of my
shell prompt.

Early on I had used the canned git prompt scripts that are floating around out
there. I felt they were way too bloated with the 42-some-odd glyphs that they
display to represent the state of your repository.

Fortunately, the informative git prompt for zsh was highly configurable
and I was able to get customize things to my liking.

What’s my liking? Just the branch name in yellow and a red ✗ if the repository
is dirty.

No arrows telling me if we’re ahead or behind. No brackets or parentheses
wrapping the information. And especially no green check mark stating the obvious
at all time.

Just the branch and an indicator if it’s dirty (and not when it’s clean).

As flexible as the git prompt for zsh was, I did find myself having to hack
together quite a bit to get down to the minimal git prompt I so desired.

No big deal, once it was working it was out of sight and out of mind.

Fast forward to a few weeks ago when I decided to drop zsh and go back to bash.
I wanted to see if bash could once again be everything I desired in a shell.

Spoiler alert, it wasn’t and I’m back on zsh.

With that, I wanted to get my bash prompt to look and behave exactly like my zsh
prompt, complete with my minimal git prompt.

I had decided to give the informative git prompt for bash and fish as
shot as it was a port of the zsh git prompt that I was already familiar with.

Unfortunately, I found it be less configurable than the original and I just
couldn’t get it to do what I wanted, so I gave in and ran it without much
tweaking.

Arrows and glyphs and all that shit I hated.

I gave it a few days though, to see if it was going to grow on me.

And it didn’t.

At this point, I set out to get the minimalist git prompt of my dreams working
without any additional dependencies in both bash and zsh.

Here’s what I came up with.

Minimalist bash git prompt

RESET=$(tput sgr0)

BLUE=$(tput setaf 4)
GREY=$(tput setaf 244)
RED=$(tput setaf 1)
YELLOW=$(tput setaf 3)

git_prompt() {
  BRANCH=$(git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/*(.*)/1/')

  if [ ! -z $BRANCH ] then
    echo -n "$YELLOW$BRANCH"

    if [ ! -z "$(git status --short)" ] then
      echo " ${RED}✗"
    fi
  fi
}

PS1='
[$BLUEw$(git_prompt)]
[$GREY]$ [$RESET]'

Minimalist zsh git prompt

git_prompt() {
  BRANCH=$(git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/*(.*)/1/')

  if [ ! -z $BRANCH ] then
    echo -n "%F{yellow}$BRANCH"

    if [ ! -z "$(git status --short)" ] then
      echo " %F{red}✗"
    fi
  fi
}

PS1='
%F{blue}%~$(git_prompt)
%F{244}%# %F{reset}'
