macaroni.nix VS Kind2

In addition, I am building a Nix library on top of haskell.nix called macaroni.nix that is gamedev-oriented and enables seamless cross-compiling from Linux to Windows. I would say it's the best option for Windows Haskell game x-compilation available today.

We just managed to get our ludum dare game finished, including standalone builds (with a very special thanks to macaroni.dev.) The game is a platformer written in sdl and yampa, with build scripts for releasing static linux and windows builds.

Aside from that, haskell/macaroni.nix make x-compilation work great. I even was able to use the h-raylib bindings with little upstream changes/overlays.

In terms of finished and playable games, it's been Ludum Dare jam games made over a weekend over the years. You can check them out here. They're all Windows-only (x-compiled from NixOS using haskell.nix via macaroni.nix), but you can play them on Linux with Wine64. If you have Nix installed, I have a script that should Just Work.

Also feel free to cut me an issue in my related project, macaroni.nix. The project is focused on x-compiling Haskell games and only supported Windows currently. But brick is a viable gamedev library, and Raspberry Pi is a desired target for gamedev someday. So I'd love to help!

Agreed. Even from a PLT perspective, I prefer Kind2 by the Kindelia Foundation for supporting inductive theorem proving (and hopefully some level of dependent types), as well as being faster to boot.

I agree. Keep in mind our language (Kind-Lang) does target the HVM, and it is really promising. The type-checker is the fastest among proof assistants, by far; the error messages are really nice; it has a fully dependent type system which is a breath of fresh air to work with. It is still not production ready though (mostly due to lack of IO), but is the extend of our effort on that direction. We hope other lang developers get encouraged to target the HVM to. Elm and Idris are great candidates for that IMO.

Another very small proof system: https://github.com/moonad/formcorejs

The core implementation is under 700 lines of JS, including the parser: https://github.com/moonad/FormCoreJS/blob/master/FormCore.js

The author has since moved on to building a runtime with optimal evaluation (https://github.com/kindelia/hvm) and a new proof language on top of that (https://github.com/Kindelia/Kind2) with considerably better performance than existing proof systems.
