A simple OOP library for Lua. It has inheritance and metamethods (operators). It uses the same API as Middleclass (with some small differences) but tries to be small and fast.
Note: For an even smaller class library take a look at this Gist
As said before, this library shares the same API as Middleclass, with some differences.
This means that you can take a look at the Middleclass wiki for examples & documentation.
While taking into account the next few differences:
staticmethods are not supported.__indexmetamethod is not supported, changing it may create errors.allocateis not part of the class, instead a private function is used.- Mixins are not supported so
includeis not supported. Child.subclassesare currently commented out to keep the simplicity, they could easily be added.- Metamethods are not inherited (Issue #1)
Just copy the lowerclass.lua file wherever you want it (for example on a lib/ folder). Then write this in any Lua file where you want to use it:
local class = require 'lowerclass'Check the spec folder for info on the spec.
Check the performance folder for info on the performance tests.
