processing

Visual arts programming language and IDE

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]
processing-java [options] --sketch=path

DESCRIPTION

Processing is a visual programming language and IDE for learning to code in the context of visual arts. It simplifies Java for creative coding.

PARAMETERS

--run

Run the sketch.

--build

Build without running.

--export

Export as application.

--present

Run in presentation mode.

--platform os

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);
}

CAVEATS

Requires Java. IDE-focused workflow. Sketches are in ~/sketchbook by default.

HISTORY

Processing was created by Casey Reas and Ben Fry at MIT Media Lab in 2001 for teaching programming in visual context.
