Command Line Arguments in 3.0.2

HorizonShadow

Hello, I have an app I wrote using some alpha version of 3.0 some time ago.

In that version, I was using command line arguments accessed via args in setup() to do some things. As of now in 3.0.2, it appears args is null.

What's the proper way to access command line arguments in 3.0.2?

if you export an application you can see the generated java

  static public void main(String[] passedArgs) {
    String[] appletArgs = new String[] { "SketchName" };
    if (passedArgs != null) {
      PApplet.main(concat(appletArgs, passedArgs));
    } else {
      PApplet.main(appletArgs);
    }
  }

so they are being passed in... to papplet main anyway. it calls setup() with no arguments though.

https://github.com/processing/processing/blob/master/core/src/processing/core/PApplet.java says

* All parameters *after* the sketch class name are passed to the sketch
* itself and available from its 'args' array while the sketch is running.

Hi,

Thanks for your replies, I've figured out the problem.

In previous versions of processing, args would be an empty array if no arguments are passed. In the latest, it's null in the same case.

Adding a null check solved my problem,

Thanks
