Showing git status on Mac terminal not working with custom bash profile

Question

I want to display my current branch status (like * meaning modified) when in a git repo over the terminal like the below. BUT, it is always displaying the following even when I switch to a git repo.

ᴾᴋᴹɴ iFeelNewsBot master wrong... ↪

When I open a new tab in my terminal it shows the proper text rendering for the current git branch seen further. How it should look

ᴾᴋᴹɴ iFeelNewsBot master * ↪

My custom bash profile code is below

# user name and color
USER_NAME='mr.universe';
TRAINER_TITLE='ᴾᴋᴹɴ'
USER_NAME_COLOR='\[\033[00m\]';
END_COLOR='\e[0m';

# \W = current working path
# \u = user
function parse_git_dirty {
  gitStatus=$(git status 2> /dev/null | tail -n1)
  clean="nothing to commit, working directory clean"
  if [[ -d "./.git" ]]
  then
    [[ $gitStatus != $clean ]] && echo "*" || echo "="
  elif [[ ! -d "./.git" ]]
  then
    echo "wrong...."
  else
    echo "STOP"
  fi
}

function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/[\1$(parse_git_dirty)]/"
}

export PS1="\[\033[40;02m\]$TRAINER_TITLE \W \[\033[36;02m\]\[\033[29;00m\]\$(git branch 2>/dev/null | grep '^*' | colrm 1 2) $(parse_git_dirty) ↪ "

It looks like the `parse_git_branch` function is never used. — ThomasW, May 29 '17 at 03:15

You're assuming every directory in a git repository has .git in it, but only the top directory of a repository has a .git directory in it. So the first if fails and elif checks if .git directory doesn't exist. Looks like the result is true and it prints 'wrong'.

You could check instead if you are inside a working tree of a git repo:

inside_git_repo="$(git -C $PWD rev-parse --is-inside-work-tree 2>/dev/null)"

if [ "$inside_git_repo" ]; then
  echo "inside git repo"
else
  echo "not in git repo"
fi

This is more reliable than looking for a .git folder.

displaying `"inside git repo"` works, but when I swap to a new non git directory `"not in git repo"` is not displayed until I open a new tab or refresh my terminal – greg May 29 '17 at 19:18
By swapping to a new branch, do you mean `git checkout aNewBranch`? And what "refreshing a terminal" means? – VonC May 29 '17 at 19:19
my mistake I mean `cd` to a new non git directory. I mean close and reopen my terminal. – greg May 29 '17 at 19:22
If you `cd` to a non git directory, it stands to reason that the script displays "non in git repo", no? – VonC May 29 '17 at 19:26
it does not, instead it displays `"not in git repo"` until I open a new tab in my mac terminal or interestingly run this command `source ~/.bash_profile` – greg May 29 '17 at 19:31
@GregUniverse but if you have cd to a **non** git directory, it should display `not in git repo`. Maybe the bash_profile, when sourced, is sourced in a folder which is not the current one? Try and add (just for testing) a line with just `pwd`, to force the display of the current folder in which the bash_profile is sourced. – VonC May 29 '17 at 19:34
