PiCrate

Create processing sketches in ruby on raspberry-pi and linux (this project is a parallel development of propane targetting the raspberry-pi, but will initially be developed on a regular linux box). The aim is to produce a gem installable app that can be run with jruby, with minimal dependencies.

To Build and Test

Clone this repo:-

Requires maven, jdk8 (can be openjdk), and a jruby install.

cd PiCrate
rake
jgem install picrate-0.0.1-java.gem

To create a template sketch:-

picrate -c my_sketch 200 200

Edit sketch (vim is good choice):-

#!/usr/bin/env jruby
# frozen_string_literal: false
require 'picrate'

class MySketch < Processing::App
  def settings
    size 200, 200
  end

  def setup
    sketch_title 'My Sketch'
  end

  def draw
    background 0
    fill 0, 0, 200
    ellipse 100, 100, 90, 70
  end
end
