puredata export?
Apr 10th, 2008, 3:34pm  
can any PD folk tell me: is there a way in PD to export a patch as an application?

basically i'm using OSC to connect PD to processing and i'd like processing to be the only thing i have to open up, then have it automatically open up the right patch in PD. so i figured if i can export my PD patch as an "application" somehow, then i could get processing to launch it automatically.

thanks....

Hi,

You don't need to export it as an app. You can launch it from Java. I've used this code in a project:
Code:

package org.jorgecardoso.pso;
import java.io.*;

public class LaunchPD {

Process process;
Runtime runtime;

String cmd;

public LaunchPD(String cmd) {
   runtime = Runtime.getRuntime();
   this.cmd = cmd;		 
}


public void start() {
   try {
	 process = runtime.exec(cmd);
   } catch (IOException ioe) {
    System.out.println(ioe.getMessage() + " " + cmd);
   }

}


public void stop() {
  if (process != null) {
     process.destroy();
  }
}



// Test

public static void main(String args[]) {

 LaunchPD lpd = new LaunchPD("../pd/bin/pd.exe -nogui -lib zexy -lib oscx");



 lpd.start();
 try {
    Thread.sleep(5000);
 }catch (InterruptedException ie) {
    System.out.println(ie.getMessage());
 }


 lpd.stop();

}
}

thanks looks like it should work nicely for what i want.

haven't got it to work yet though (i'm on a mac) using this (returns a "cannot execute" error):

Code:

LaunchPD lpd = new LaunchPD("../../Applications/Pd-extended.app");


any idea what i need to do differently on a mac?

(and ultimately i would like to do something like this:

Code:

LaunchPD lpd = new LaunchPD("../../Applications/Pd-extended.app -nogui -open /path/to/my/file");


(btw, i also tried

Code:

String[] params = { "../../Applications/Pd-extended.app" };
open(params);


which opened up pd correctly, but if i added parameters:

Code:

String[] params = { "../../Applications/Pd-extended.app","-open path/to/my/file" };
open(params);


it failed to open anything (though with no error)
