Princeton Standard Libraries Jruby wrapper

I was going through the Algorithms 4th edition and wanted to write the algorithms in ruby instead of the default java. The book uses the Princeton Standard Libraries to help clarify the code.

Installation

Add this line to your application's Gemfile:

gem 'princeton_standard_libraries'

And then execute:

$ bundle

Or install it yourself as:

$ gem install princeton_standard_libraries

Usage

require 'princeton_standard_libraries'

n = 50
Java::StdDraw.set_xscale(0,n)
Java::StdDraw.set_yscale(0,n*n)
Java::StdDraw.pen_radius = 0.01

1.upto(n) do |i|
  Java::StdDraw.point(i, i)
  Java::StdDraw.point(i, i*i)
  Java::StdDraw.point(i, i*Math.log(i))
end
