Command Line Options Syntax (Read 1431 times)

metaphorz Junior Member Offline Posts: 53	Command Line Options Syntax May 26^th, 2005, 7:46pm I am trying to locate where the command line syntax options (such as -present and -display) are documented. In particular, I see that "-display 1" generates a full screen display. What is the corresponding option for a windowed display? Are there other options we should know about? Thanks.

In this thread are some ideas about that. http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Contribution_3DOpenGL;action=display;num=1114730164

Ok I figured this out. (really simple)

Just omit the arguments and then it launches in its correct size:

static public void main(String args[]) {
PApplet.main(new String[] { "boxes02" }); // boxes02 is the name of the jar
}

But now my next question would be:
How can I pass arguments to the program when launching it from the command line?

In Java one could do:

public static void main(String[] args){
new Framework(args[0], args[1]);
}

where the constructor would assign the arguments passed from the command line? How does one do that in Processing?
There is no constructor or what? Perhaps there is... I'll go and check now.

But any tips are welcome.

Thanks for that Fry, this clarifies things.

I had a look at the PApplet source file, but I don't get where to get the 2nd argument though (in the sketch).

The first argument (the name of the sketch "boxes02") is the first argument, no probs.

The second argument should be the number of the boxes:
static public void main(String args[]) {
println("args length is " + args.length);
PApplet.main(new String[] { args[0], args[1]});
}

Where I run this in the command line:
java -jar boxes02.jar boxes02 122

But what I want is to have somewhere (in a constructor - no you don't recommend that) a line where I get the number of boxes from the command line into the sketch. such as:

int numBoxes = int(args[1]); // the second argument I pass from cmdline

Now I've tried to put it into the setup() method in my sketch:

void setup(){
println("args 1 " + args[4]);
....

and I thought that args[4] would be the number passed (as the first arguments to PApplet seem to be --external --display=1, sketchLoc and sketchName.

Where can I get at the number passed after the sketchname in the commandline?
java -jar boxes02.jar boxes02 122

Thanks for all help

that you just use the regular 'main'.

PApplet.main(new String[] { "boxes02.jar", "boxes02", "122" });

and PApplet's main() will subset the args passed in so that inside setup():

void setup() {
String param1 = args[0];
String param2 = args[1];
}

but you have to use PApplet.main() for that. and the -jar option should work on export as of rev 0092 or so, but not for things that use other libraries.
