Object Oriented Ruby - new examples Archive [link] - a straightforward example of a class definintion, no inheritance, nothing fancy (thout it does have an attribute accessor)[link] - a demonstration that shows inheritance, embedding of classes within a module, static variable and methods, operator overloading, a singleton method and much more. There are plenty of comments in the source code of this example.[link] - showing the difference between object and class (dymanic and static) variables.[link] - command line parameters to a Ruby program[link] - BEGIN and END blocks, and autosplit[link] - a comparison of symbols and strings in Ruby[link] Commenting a regular expression in Ruby
