arduino-fsm: Trigger is not reentrant

Hi,

I would like to be able to call trigger from within a “enter” or “transition” function. Do you see a easy modification of your lib to be able to write something like this:( modify your light_switch.ino and change just de bellow functions)

void on_light_on_enter()
{
  Serial.println("Entering LIGHT_ON");
  delay(2000);
  fsm.trigger(FLIP_LIGHT_SWITCH);
}

void on_light_off_enter()
{
  Serial.println("Entering LIGHT_OFF");
  delay(2000);
  fsm.trigger(FLIP_LIGHT_SWITCH);
}

void loop()
{
  fsm.trigger(FLIP_LIGHT_SWITCH);
}

My goal is to write some “routing state” that would automatically branch to another state depending on the value of some sensor. Something like:

void on_router_enter()
{
   int a = readSensor()
   if (a>5) {
       fsm.trigger(GO_STATE_HIGH);
   } else {
       fsm.trigger(GO_STATE_LOW);
   }
}
