TLDR

Launch Processing IDE

$ processing

Run sketch from command line

$ processing-java --sketch=[path/to/sketch] --run

Export as application

$ processing-java --sketch=[path] --export

Build without running

$ processing-java --sketch=[path] --build

SYNOPSIS

processing [options]

Target platform.

--output dir

Output directory.

$ # Launch IDE
processing

# Run sketch
processing-java --sketch=/path/to/sketch --run

# Export for all platforms
processing-java --sketch=/path/to/sketch --export

# Build only
processing-java --sketch=/path/to/sketch --build

SKETCH EXAMPLE

$ void setup() {
  size(400, 400);
}

void draw() {
  background(255);
  ellipse(mouseX, mouseY, 50, 50);
}
