# This is a .bash_profile file that you can write to your home directory to give
# you a custom shell prompt that will include the git branch and status of your
# current working dir as well as the current Xcode version.
#
# This is really handy when you're running multiple Xcode versions on your machine and have to run
# command line builds such as carthage, fastlane or cocoapods which can fail or do the
# wrong thing and waste a lot of time if xcode-select is not using the version of Xcode tools you expect.

# These git parts were verbatim copied from http://ezprompt.net

# get current branch in git repo
function parse_git_branch() {
BRANCH=`git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
if [ ! "${BRANCH}" == "" ]
then
STAT=`parse_git_dirty`
echo "[${BRANCH}${STAT}]"
else
echo ""
fi
}
# get current status of git repo
function parse_git_dirty {
status=`git status 2>&1 | tee`
dirty=`echo -n "${status}" 2> /dev/null | grep "modified:" &> /dev/null; echo "$?"`
untracked=`echo -n "${status}" 2> /dev/null | grep "Untracked files" &> /dev/null; echo "$?"`
