A simple OOP library for Lua. It has inheritance, metamethods (operators), class variables and weak mixin support.
|

|

|

|
|
Quick Look
|
||
|
|
==========
|
||
|
|
|
||
|
|
```lua
|
||
|
|
local class = require 'middleclass'
|
||
|
|
|
||
|
|
local Fruit = class('Fruit') -- 'Fruit' is the class' name
|
||
|
|
|
||
|
|
function Fruit:initialize(sweetness)
|
||
|
|
self.sweetness = sweetness
|
||
|
|
end
|
||
|
|
|
||
|
|
Fruit.static.sweetness_threshold = 5 -- class variable (also admits methods)
|
||
|
|
|
||
|
|
function Fruit:isSweet()
|
||
|
|
return self.sweetness > Fruit.sweetness_threshold
|
||
|
|
end
|
||
|
|
|
||
|
|
local Lemon = class('Lemon', Fruit) -- subclassing
|
||
|
|
|
||
|
|
function Lemon:initialize()
|
||
|
|
Fruit.initialize(self, 1) -- invoking the superclass' initializer
|
||
|
|
end
|
||
|
|
|
||
|
|
local lemon = Lemon:new()
|
||
|
|
|
||
|
|
print(lemon:isSweet()) -- false
|
||
|
|
```

Installation
|
||
|
|
============
|
||
|
|
|
||
|
|
Just copy the middleclass.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:
|
||
|
|
|
||
|
|
```lua
|
||
|
|
local class = require 'middleclass'
|
||
|
|
```
|
||
|
|
|
||
|
|
Specs
|
||
|
|
=====
|
||
|
|
|
||
|
|
This project uses [busted](http://olivinelabs.com/busted/) for its specs. If you want to run the specs, you will have to install it first. Then just execute the following:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
cd /folder/where/the/spec/folder/is
|
||
|
|
busted
|
||
|
|
```
|
||
|
|
|
||
|
|
Performance tests
|
||
|
|
=================
|
||
|
|
|
||
|
|
Middleclass also comes with a small performance test suite. Just run the following command:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
lua performance/run.lua
|
||
|
|
```
