command line option to override ig_config?

[Amerio.Stephane]

Hi,

I'm pretty sure this exists but can't put my hand on it in the doc:

Is there any way to pass IG/CIGI/DIS options in the command line in the launch script to override any settings in the ig_config.xml?

Thanks!

Hello! 

At the moment you can only override the following parameters:

-ig_config "path/to/ig_config.xml"

-cigi_host "127.0.0.1"
-cigi_send_port 8899
-cigi_recv_port 8899

-dis_address "127.255.255.255"
-dis_multicast 1/0
-dis_site_id 11
-dis_exercise_id 22
-dis_app_id 33
-dis_port 3000

Let me know if you need any additional parameters.

Thanks!

Hi, would it be possible to add something for the default view ID and the default database too?

Thanks!

Hello! 

No, there are no such built-in commands. but you can define them by yourself

int getCommandArg(const char *arg_name, int default_value)
{
	Engine *engine = Engine::get();
	for (int i = 0; i < engine->getNumArgs() - 1; i++)
	{
		const char *name = engine->getArg(i);
		if (name[0] == '-')
		{
			name++;
			if (!strcmp(name, arg_name))
			{
				return engine->getArgi(i + 1);
			}
		}
	}

	return default_value;
}


int AppSystemLogic::init()
{
//.....
	
	int default_view = getCommandArg("default_view", ig_manager->getCurrentView());
	// change config value
	ig_manager->getConfig()->setValue("IG.default_view_id", default_view);
	// or directly apply
	ig_manager->setCurrentView(default_view);
	
	int default_database = getCommandArg("default_database", ig_manager->getCurrentDatabaseID());
	// change config value
	ig_manager->getConfig()->setValue("IG.autoload_database", default_database);
	// or directly apply
	ig_manager->loadDatabase(default_database);

	return 1;
}
