DESCRIPTION:

Superators are a superset of new Ruby operators you can create and use. This is a fork of the original superators gem that adds compatibility with MRI 1.9 and other fixes.

FEATURES/PROBLEMS:

• Presently a superator operand must support having a singleton class. Because true, false, nil, Symbols, and Fixnums are all specially optimized for in MRI and cannot have singleton classes, they can't be given to a superator. There are ways this can be potentially accounted for, but nothing is in place at the moment, causing this to be classified as a bug.

• When defining a superator in a class, any operators overloaded after the superator definition will override a superator definition. For example, if you create the superator "<---" and then define the <() operator, the superator will not work. In this case, the superator's definition should be somewhere after the <() definition.

• Superators work by handling a binary Ruby operator specially and then building a chain of unary operators after it. For this reason, a superator must match the regexp:

  /^(\*\*|\*|\/|%|\+|\-|<<|>>|&|\||\^|<=>|>=|<=|<|>|===|==|=~)(\-|~|\+)+$/
  

SYNOPSIS:

Below is a simple example monkey patch which adds the "<---" operator to all Ruby Arrays.

class Array
  superator "<---" do |operand|
    if operand.kind_of? Array
      self + operand.map { |x| x.inspect }
    else
      operand.inspect
    end
  end
end
