classic
A minimal class module for Lua that provides object-oriented programming features with simplicity and performance.
What is classic?
Classic is a tiny class module for Lua that provides object-oriented programming capabilities, allowing developers to create classes, inheritance, mixins, and type checks. It solves the need for structured code organization in Lua projects without introducing unnecessary complexity or performance overhead.
Lua developers, especially those in game development or scripting contexts, who want a simple and performant way to implement OOP patterns in their codebases.
Developers choose Classic for its minimal footprint, ease of use, and focus on essential OOP features, avoiding the bloat of larger frameworks while maintaining good performance and readability.
Overview
Tiny class module for Lua
Use Cases
Best For
- Adding object-oriented programming to Lua scripts in game engines like LÖVE or Roblox
- Organizing code in lightweight Lua applications with classes and inheritance
- Implementing mixins for reusable functionality across different Lua modules
- Creating structured prototypes or entities in Lua-based game development
- Teaching OOP concepts in Lua due to its simplicity and clear syntax
- Extending existing Lua projects with type checking and metamethods
Not Ideal For
- Projects requiring advanced OOP features like interfaces, abstract classes, or multiple inheritance beyond single inheritance and mixins
- Large-scale applications that need built-in serialization, validation, or dependency injection for complex object management
- Teams looking for extensive documentation, tutorials, and community plugins typically found in larger frameworks
Pros & Cons
Pros
The module is just a single file that can be dropped into any project with `Object = require 'classic'`, ensuring no bloat and easy integration.
Methods like `:extend()` for inheritance and `:implement()` for mixins are intuitive, making OOP accessible without complex syntax, as shown in the README examples.
Designed to avoid over-abstraction, it prioritizes runtime performance, which is ideal for Lua applications in performance-sensitive areas like game development.
The `:is()` method allows easy runtime type checking, useful for debugging and ensuring object correctness, demonstrated in the type checking example.
Cons
Lacks support for private members, interfaces, and multiple inheritance, which can be restrictive for complex object-oriented designs requiring more advanced patterns.
The README provides only basic examples without in-depth guides on error handling, best practices, or edge cases, leaving developers to figure out advanced usage on their own.
Objects cannot be easily serialized or deserialized, requiring manual implementation for persistence or network transmission, adding overhead for data-heavy applications.
