I am new to Processing development environment, I did my homework and all I found is to import processing libraries into Java IDE (eclipse) and use debugging, I am wondering if there is a PDE plugin that can help with intellisense and debugging as for small sketches PDE is very convenient.
Since the launch of Processing 3, debugging is now a native feature of the Processing IDE.
In the screenshot below, you'll see a new Debug
menu. I set breakpoints on the setup()
and draw()
methods as indicated by the <>
marks in the line numbers. To the right is a popout window listing variable and object values, etc.
From the Preferences menu, check the box Code completion with Ctrl-space.
Then, you can start typing a function like ellipse
and press CTRL+Space to pop intellisense. Moreover, with that turned on, accessing properties or methods of an object by typing a .
after should automatically pop intellisense.
Finally, you could take advantage of a more powerful IDE by importing the processing core.jar into any Java project. The core.jar file is located relative to your Processing installation, such as:
OSX: /Applications/Processing 3.0.1.app/Contents/Java/core/library/core.jar
Windows: \Program Files\processing-3.0.2\core\library\core.jar
In Processing 1 and 2, this must be run as Applet. In Processing 3, run as Java Application. Here's an example to demonstrate:
import processing.core.*;
public class Main extends PApplet {
// In Eclipse, run this project as Java Application (not Applet)
public static void main(String[] args) {
String[] a = {"MAIN"};
PApplet.runSketch(a, new Main());
}
public void settings() { // <-- that's different
size(500, 500); // necessary here to prevent runtime IllegalStateException
}
public void setup() {
// other one and done operations
}
public void draw() {
ellipse(mouseX, mouseY, 40, 40);
}
}
