#  Usage
#  -----
#      git-sync /path/to/repo
#      git-sync # current dir
#      git-sync # if you want sync all files
#      git-sync -u # if you want only sync files explicitly added via `git add filename`

if [ "$BASH_ARGV" != "" ] && [ -d $BASH_ARGV ]; then # if last argument is dir
  echo "Running in dir $BASH_ARGV."
  cd $BASH_ARGV
fi

git pull

if [[ $1 == "-u" ]]; then # if first argument is -u
  echo "Ignoring new files."
  add_arg="-u"
else
  add_arg="-A"
fi
git add $add_arg

CHANGED=$(git diff --name-status HEAD)
if [[ -z $CHANGED ]]; then
    echo -e "No changes to commit.\nEverything in sync."
    exit 0
fi    
echo -e "Files in changelist:\n$CHANGED\nCancel and run 'git difftool HEAD'/'git diff HEAD' to review changes."

read -p "Commit message (or Ctrl+C to cancel): " commit_message
test -n "$commit_message" || commit_message="bump" #default value if empty
git commit -a -m "$commit_message"

# Try to push, if no sucess run merge and push again
git push origin master \
    || git pull \
    || git mergetool \
    && git commit -a -m "merging" \
    && git push origin master
