  This is a nice guide for ruby:

  • Ah. You posted before I could finish my last tid-bit of links ;)– stewdio1/2

    Good work stewdio .. you've created an interesting thread in amongst a sea of COMPLETE SHITE– lukus_W2/2

  Not really for the ruby version of processing, but useful nevertheless:

  If you already know Processing every one of those commands should be familiar to you. They're just the "Ruby-ized" version. (Java makes a lot of use of CamelCase variable names, while Ruby prefers under_scores instead.) Here's a complete list of Processing commands : http://processing.org/reference

  And here's everything you need to know about Ruby.

  I highly recommend their "Ruby in Twenty Minutes" tutorial. They're not kidding. It's quick. And it makes sense.

  This is a nice editor for ruby - it's new, and improving all the time .. works a bit like textmate (uses textmate bundles), and it's free. Check it out.

  http://redcareditor.com/

  • Works for loads of other file types / languages too..– lukus_W1/4

    Cool. Trying it out now.– stewdio2/4

    Gave it a shot. Interesting stuff, but I think I'll stick with TextMate for now.– stewdio3/4

    Yeah, it has a way to go - I'm using linux, so textmate isn't possible for me.– lukus_W4/4

  Ok. If you want to get all psychedelic with your color theory try this update and save it as MyCubes2.rb (or whatever you want to call it, it doesn't matter). And here's a little HSB-related color review while you're at it :
  http://en.wikipedia.org/wiki/HSL…

  . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

  class MyCubes < Processing::App
  load_library :opengl

  def setup
  size 640, 360, OPENGL
  frame_rate 30
  @x_degree = 45
  @y_degree = 0
  @color_hue = 0
  color_mode HSB, 360
  no_stroke
  end

  def draw
  background_hue = ( @color_hue + 180 ).modulo 360
  background background_hue, 360, 360, 360
  lights
  push_matrix

  translate width / 2, height / 2, 0
  rotate_x radians( @x_degree )
  rotate_y radians( @y_degree )
  fill @color_hue, 360, 360, 320
  box 100

  pop_matrix
  @x_degree = ( @x_degree + 1 ).modulo 360
  @y_degree = ( @y_degree + 2 ).modulo 360
  @color_hue = ( @color_hue + 1 ).modulo 360
  end

  end
  MyCubes.new :title => "My COLORFUL Cubes!"

  Ruby + Processing = RubyProcessing

  Or for the more visual crowd :

  Hmmmm... I'd love to get some other QBNers excited about this besides Lukus and myself.

    I may open my mind.... I worked with a ROR egotist/cult member who gave me PTSD about ruby....– vaxorcist3/5

    Good point. I've run into that too. (I hope I don't come off that way!)– stewdio4/5

  I'm barely getting to grips with Processing Java running local, hacking others' code - I've still no clue what Ruby actually *is*.

  @drgss. Yes. Typographically clean. Compare Ruby to Java for instance and you'll see that Ruby does a great job getting rid of excessive semicolons, curly braces, parenthesis, etc. There's a real flexibility with how you write Ruby code so instead of just writing code that the computer can understand you can write code that looks clean and better communicates to other humans what your intent is. There's a great quote from the book Structure and Interpretation of Computer Programs: "Programs should be written for people to read, and only incidentally for machines to execute."

  I have a deep appreciation for clean coding. When I work with other designers and they hand me code that is concise and legible it draws my instant respect.

  • gah - got there before me– lukus_W1/2

    Ruby is great... and fun, and elegant, as long as you are within it's boundaries.... otherwise SUCKS– vaxorcist2/2

  Ruby's a really nice programming language - said to be easier to use than Java ..

  With many high-level languages, there are a lot of weird quirks that are necessarily to write code that won't break.

  Because of this, a lot of the time, a beginner often can't get to grips with creating anything worthwhile, because they need to know about things like 'casting' and 'precedence', the number of bits each datatype is going to consume or where to add a semicolon to end each statement. The details get in the way.

  With ruby, a lot of the time this knowledge isn't needed - stuff just works. It's a much nicer language to code in.

  • Ha. This time you beat me to it.– stewdio

  @detritus

  Ruby is a fairly young programming language, first publicly released in 1995. It was created by Japanese programmer Yukihiro "Matz" Matsumoto. And if you're running OS X you already have Ruby installed :) For more historical info I found the Ruby Wiki page to be decent: http://en.wikipedia.org/wiki/Rub…)

  Ruby gained significant popularity with the rise of Ruby on Rails. (Rails is a web application framework written in Ruby.) In fact, web searches for things having to do with Ruby will usually land you on a page that's actually discussing Rails. Here's the homepage for RoR: http://rubyonrails.org

  But Ruby is good for more than just building websites. Right now I'm excited about using it to create animated data visualizations. Ruby-Processing takes the commands and libraries I was used to in Processing and allows me to use them in Ruby. That means I can hit the ground running. And I found programming in Ruby to be much more rewarding that coding in Java (Processing).

  I think the live coding feature could be great for visualisations / vjing.

  I always wanted to get into this. How's the learning curve coming from an AS3 background?

  @acrossthesea

  Forget learning curves ;) Just follow my instructions at the top of this post and in about 5 minutes you'll be playing with a red cube rotating in space. And you'll want to mess with it.

  That's all you need, the urge to mess with the code. Little thoughts like "I bet I could make the cube larger." Or "I wonder if I can just copy what he's doing with the X-axis and make it rotate on the Z-axis instead." Before you know it you'll be tackling much bigger stuff. You'll be golden.

  • Thanks, I'll give it a shot!– acrossthesea1/2

    Awesome :)– stewdio2/2

  Twitter, Github, YellowPages dot com and Hulu are all written in Ruby on Rails to various degrees.

  For some reason Ruby inspires serious devotion from its users. I used to work with a programmer who was really into it. He talked about Ruby like it was his girlfriend, kinda weird if you ask me ;)
