Middleclass is a lightweight object-orientation library for Lua providing classes, inheritance, metamethods, class variables, and mixin support in a single file. It is widely used in Lua game development and scripting.

Use cases

• add classes and inheritance to lua code
• object-oriented programming in lua
• lua class library with mixins
• define classes with constructors in lua
• operator overloading via metamethods in lua
• oop for love2d or game scripting

When to choose

• you want a small, dependency-free, single-file OOP solution for Lua
• you need inheritance, class variables, and mixins with a simple API
• you are writing games or scripts in Lua and want familiar class semantics

When to avoid

• you need multiple inheritance or advanced type checking
• you are using Lua 5.4+ and prefer native or alternative OOP mechanisms
• your project requires a full-featured class system with strict typing
