middleclass changelog

Version 4.1.1

  • Fixed a bug in which static values which evaluated to false were not available in subclasses (#51, thanks @qaisjp for the patch!)
  • isInstanceOf does not throw an error any more when its first parameter is a primitive (#55) (This effectively undoes the change introduced in 4.1.0)

Version 4.1.0

  • Simplifies implementation of isInstanceOf and isSubclassOf. They will now raise an error if their first parameter (the self) isn't an instance or a class respectively.

Version 4.0.0

  • Unified the method and metamethod lookup into a single algorithm
  • Added the capacity of setting up the __index metamethod in classes
  • Removed global Object (classes created with class(<name>) have no superclass now)
  • Removed default method Class:implements(<mixin>)
  • Renamed several internal functions

Version 3.2.0

  • Changed the way metamethods were handled to fix certain bugs (un-stubbed metamethods could not be inherited)

Version 3.1.0

  • Added Lua 5.3 metamethod support (__band, __bor, __bxor, __shl, __bnot)

Version 3.0.1

  • Added __len, __ipairs and __pairs metamethods for Lua 5.2

Version 3.0

  • Anything that behaves reasonably like a class can be a class (no internal list of classes)
  • The class global function is now just the return value of require 'middleclass'. It is a callable table, but works exactly as before.
  • The global variable Object becomes class.Object
  • The global function instanceOf becomes class.Object.isInstanceOf. Parameter order is reversed.
  • The global function subclassOf becomes class.Object.static.isSubclassOf. Parameter order is reversed.
  • The global function implements becomes class.Object.static.implements. Parameter order is reversed.
  • Specs have been translated from telescope to busted

Version 2.0

  • Static methods are now separated from instance methods
  • class.superclass has now become class.super
  • It's now possible to do class.subclasses
  • middleclass is now a single file; init.lua has dissapeared
  • license is changed from BSD to MIT. License included in source FTW
