lupy

A small Python-style OO implementation for Lua. It also gains some good features from Ruby.
It has been tested on Lua 5.2.3 using the examples in repo. Welcome to fork and test it more.

Philosophy

"Things should be as simple as possible, but no simpler." [1]

Usage

Copy lupy.lua file to your project or where your lua libraries stored.
Then write this in any Lua file where you want to use it:

local class = require 'lupy'

More usage can be found in the examples.

Quick Look

local class = require 'lupy'

class [[Person]]

  function __init__(self, name)
    self.name = name
  end

  function say(self, msg)
    print(self.name.." says: "..msg)
  end

_end()

local I = Person("Peer")

I.say("Hello world!")

-- Peer says: Hello world!
