def callback_function(event):
    print("update for remove filtered policy callback, event: {}".format(event))

def get_examples(path):
    examples_path = os.path.split(os.path.realpath(__file__))[0] + "/../examples/"
    return os.path.abspath(examples_path + path)

if __name__ == "main":
    test_option = WatcherOptions()
    test_option.host = "localhost"
    test_option.port = "6379"
    test_option.channel = "test"
    test_option.optional_update_callback = callback_function
    w = new_watcher(test_option)
    
    e = casbin.Enforcer(
        get_examples("rbac_model.conf"), get_examples("rbac_policy.csv")
    )
    e.set_watcher(w)
    # then the callback function will be called when the policy is updated.
    e.save_policy()
