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. Drop the C
and you get pirate, or and an e
and get PiCreate
, a happy coincidence?
To install from rubygems
jgem install picrate
To Build and Test
Clone this repo:-
Requires maven, openjdk11 (to build, uses release
flag), and a jdk8 and jruby to install.
cd PiCrate
rake # assumes an installed version of vanilla processing
jgem install picrate-0.8.0-java.gem
To create a template sketch:-
picrate -c my_sketch 200 200
Edit sketch (vim is a 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
