The IDE helps you creating images, which can be processed by KaForkL.
imagemagick (the convert binary in your path)
The IDE is still very alpha and should be used with care. You can only work on existing images and all images will be saved into you current cwd as ide.out.png. To run the IDE add the image you want to work with as a parameter on CLI.
But using the IDE has some major advantages:
You can debug your code, starting the interpreter at every point of the image by setting the start point and just run.
You see the debug output and the program output in separate windows.
The current processors are highlighted and by clicking on them you can introspect their current stack.
You can run your program step-by-step.
You can easily set values of pixels using the GUI interface - far easier then everything else - for sure!
