Topic: what game library to use for Lean?
Srayan Jana (Aug 23 2025 at 06:59):
I’ve done a bit of googling and found a couple
https://github.com/funexists/raylean/
-
raylib bindings that use Rust for some odd reason
https://github.com/KislyjKisel/Raylib.lean -
more “traditional” raylib bindings
https://github.com/Anderssorby/SDL.lean -
SDL bindings (seem abandoned)
I don’t think this is really the same thing, but honorary mention to the Lean Game Server
https://github.com/leanprover-community/lean4game
Has anyone tried any of these? Are there more that I haven’t heard of yet?

On closer inspection, Raylean seems more like a full fledged game engine, including an ECS (!!!!) and a sample game

Haven't tried any of those, but just wanted to say I love the name of that organization, "fun exists"!

indeed, lean4game does not really have anything to do with video games and doesn't use any of the mentioned libraries.
