#
# git-track should be added to your path.
# Sets up auto-tracking of a remote branch with same base name.
# Can set up "git track" so it feels built-in:
# git config --global --add alias.track '!git-track'
#
# Update: changed the way current branch name is determined, see:
# http://git-blame.blogspot.com/2013/06/checking-current-branch-programatically.html
# Also made sure that when not on any branch (in detached head state) - that track would
# not do anything
if tracking=$(git symbolic-ref --short -q HEAD)
then
  git config branch.$tracking.remote origin
  git config branch.$tracking.merge refs/heads/$tracking
  echo "tracking origin/$tracking"
else
  echo not on any branch
