What is your sketch? What do you have at the line 103?

my sketch is just a basic test, just trying to get processing-in-emacs working ('line 103' should be related to Sketch.java, and I didn't build from source so I have no idea, unless I get processing fully working, I won't even try to build it).

anyway, here is the code I try to run (I get the same error with any other code..):

1. void setup() {
       size(200, 200);
       stroke(255);
       frameRate(30);
       noLoop();
   }
   
   void draw() {
       background(0);
       line(0, 100, width, 100);
   }
   

processing itself looks amazing but really, with all respect, I can' t write code in the default IDE.

Indeed, there is no room for NPE from your code... (I wanted to avoid the case of plain old error from the programmer, it happens more often than you can believe...)

I can't really help you there, as I don't use Emacs. I agree that the PDE editor is... not perfect. But you can write your code in your favorite editor (that's what I do, except for small tests), and load the sketch in the PDE to run it. I don't even use the "External editor" setting, as I want to be able to make small fixes in the PDE. The downside is that you have to reload the sketch each time you want to test it (it is better from the toolbar).

Hi,

unfortunately I'm using processing-1.5 (and archlinux as well).

this issue was added to github some months ago but there were no updates since some time...

cheers,

Hi,

do you need a closing bracket? to match the open one next to the PApplet line you add?
