# This script have two roles
#
# 1) Ensure that we have latest varsion (from git)
# 2) Load the tools into $PATH variable

# Current working directory
pwd=`pwd`

# Directory of this script
dir=`dirname $0`

# File with last update date
last=$dir/last_update

# Current date
date=`date +%Y-%m-%d`

# Update git repository
# We are expecting no local changes, thus the pull instead of fetch
function update() {
  echo "Updating Jarcec's command line tools"
  cd $dir
  git pull
  echo $date > $last
}

# For the case we never run update, run it now
if [[  ! -f $last ]]; then
  update
# For now, call the update once a day
elif [[ `cat $last` < `date +%Y-%m-%d` ]]; then
  update
fi

# Finally put all the tools into the path
export PATH="$PATH:$dir"

# Return to original working directory
cd $pwd
