Golly is a pure Lua /gameplay/ programming library written in Fennel that can be dropped into any engine. Out of the box Golly gives you:

• A fully featured ECS framework (on top of tiny-ecs)
• A game logic focused OOP framework. Strong mixin support, zero support for inheritence (composition only!). Methods support metadata informing the engine /when/ to call the method (events such as update, draw, redux state change, or user defined events)
• Redux style state management
• A timeline tool which leverages lua's coroutines for succinctly writing gameplay code.

There are many small tools and library functions as well. The API is still experimental and undocumented. Anticipating a v0.1 alpha release soon

Right now, there is a minimal Love2D example showcasing a basic class and the timeline concept located at ./love-example.fnl To play with it, clone the repo and just run love ./

A REPL will open up over stdio. There is a global variable called scene you can play with. Try (scene:add-entity (foo))
