DESCRIPTION

Platypus provides a generalized type conversion system, method overloading and psuedo-classes.

RELEASE NOTES

Please see HISTORY file.

SYNOPSIS

Type Conversion

"1234".to(Float)    => 1234.0  (Float)

Time.from("6:30")   => 1234.0  (Time)

Method Overloading

To overload a method use the #overload method to define new functionality based on a specified type interface.

class X
  include Overloadable

  def x
    "hello"
  end

  sig Integer

  def x(i)
    i
  end

  sig String, String

  def x(s1, s2)
    [s1, s2]
  end
end

Psuedo-Classes

class KiloType < Type
  x % 1000 == 0
end

KiloType === 1000
KiloType === 2000
