A Ruby Module that adds attribute methods and other useful methods to make working with exact byte-lengths easier and quicker.

gem install byteobject

class MyClass
  #This gives you all of the attribute methods and other features.
  include ByteObject

  #They work like normal attr_ methods, taking single symbols...
  attr_u8bit :id

  #... or multiple.
  attr_s16bit :hp, :mp, :strength

end

There are 8 total attribute methods, two each for 8-, 16-, 32-, and 64-bit values. One method makes attributes for unsigned values, and the other for signed values.

The writer method created by these will automatically clamp any value outside of the byte's range. So if you try to write 1000 to an attr_s8bit-generated attribute, it'll write 127 instead.
