Hello! I did some debugging yesterday and found that when I load the network via TraCi it *uses the OptionsParser* and when I load the network via *sumo-gui it uses SAXParser*. This is because myArgC is 3 via Traci and 0 via sumo-gui at this point in the code: https://github.com/eclipse/sumo/blob/master/src/utils/options/OptionsIO.cpp#L131
myArgV values using TraCi: myArgV[0]: /home/tiago/src/sumo/bin/sumo-gui myArgV[1]: -c myArgV[2]: overtaking.sumo.cfg Does anyone know if this is the expected behavior? Do you know if the OptionsParser can parse *random_number* correctly? Thanks in advance!
