A simple class library for Lua

class.lua

--classes in lua
local classes = {}
function classes.create(name, inherit)
    local class = setmetatable({}, inherit or classes)
    class.__name = name
    class.__index = class
    return class
end
--meta
setmetatable(
    classes,
    {
        __call = function(self,name,inherit)
            return classes.create(name,inherit)
        end
    }
)
classes.__index = classes
function classes:__call(...)
    return self:new(...)
end
function classes:new(...)
    return (self.constructor and self:constructor(...)) or setmetatable({}, self)
end
function classes:__add(name)
    assert(type(name) == "string", ("Invalid use of (Class)+(%s) proper use (Class)+(string)"):format(type(other)))
    return classes(name, self)
end
function classes:isOf(other)
    assert(type(other) == "table","Invalid use of (class:isOf(other)) provided object is not a table")
    if getmetatable(self) == other then
        return true
    elseif getmetatable(self) == classes then
        return false
    else
        return getmetatable(self):isOf(other)
    end
end
function classes:multiClass(name, ...)
    --this is a special case
    local group = {...}
    local mt = {}
    function mt:__index(key)
        for i, v in ipairs(group) do
            if v[key] then
                return v[key]
            end
        end
    end
    --create class
    local class = classes(name)
    setmetatable(class, mt)
    return class
end
--end
return classes

Sorry for not telling you how to use it.
To create a class you can either do class.create(“name”,[inherited class]) or class(“name”,[inherited class]).
To use a class you first have to create a constructor like

local class = require(“class”)(“Test”)
function class:constructor(name,value)
return setmetatable({name=name,value=value},self)
end
--test object
local object = class(“some”,”value”)
print(object.name,object.value)
print(object:isOf(class))

This snippet should result in the lua console outputing some, value, and true
That’s all to using the basics of it
