How to use

run svn/trunk/run.command from Terminal. Then File dialog will appear and select this file. Java applet will be launched.

svn/trunk/examples/basics/arrays/array_objects.rb

Or you can launch this applet from terminal.

$ jruby aco.rb examples/basics/arrays/array_objects.rb

Open this file from text editor.

svn/trunk/examples/basics/array/array_objects.rb

On line 47, please edit below code and save this file.

p.stroke 4 * p.second, 0, 0

Do your applet stroke color trun into red ? When you save, a definition of Mod class will be changed. Next on line 4, please change code like this.

size 300, 300

If you know Processing, you anticipate window size will be changed. But setup() is called only once when applet launching. So, It is not necessarily the case that the result is not changed by code.

If you would like to run program from beginning, Set window focus to the applet and hit key,

⌘ + R (or Ctrl + R)

setup() function will be called and window size will become bigger.

If you meet error while coding, fix your code from stack trace information, set focus to the applet and type ⌘ + R. This applet will be relaunched.
