Ruby - console sketches

Overview:

This is inspired by processing.org, and is a basic attempt to faciliate drawing to a terminal console within a Ruby Script.

The primary concepts reside in the lib/sketch.rb

Subclasses of that Ruby class get two methods, and the overall template of a sketch looks like:

require_relative '../lib/sketch.rb'

class ConsoleSketch < Sketch
  def setup
    # called once at startup
  end

  def draw
  	# called once per frame  
  end
end

And there are some basic methods provided to subclasses:

Method	Description
`width`	Returns the width of the console window in terms of number of characters.
`height`	Returns the height of the console window in terms of number of characters
`color(r, g, b)`	Returns a representation of the RGB color (0-255) based, that can be passed into color setting functions
`color_hsl(h, s, l)`	Returns a representation of the HSL color (0-1) based, that can be passed into color setting functions
`stroke( color )`	Sets the stroke color of text display)
`fill( color )`	Sets the background color of text output.
`print_at(text, x, y)`	Displays the `text` string at the specified coordinates.
`fill_background`	Fills the screen with the current `fill()` color.
