213 raylib examples ported to jank, each one its own small Leiningen project with a project.clj, a bb.edn and one source file. raylib comes from the official org.jank-lang.commons/raylib-sys package, and the four helpers several demos share live in common/.
The gallery shows every demo with its recording.
You need Leiningen, a working jank and babashka. The demos are macOS-first.
git clone --recurse-submodules https://github.com/b12n-oss/raylib-jank-demo
cd raylib-jank-demo
bb doctor # Leiningen, a jank that starts, the asset submodule
bb starfield # from the repo root
cd starfield && bb run # from inside the demo
The first demo you run builds raylib-sys natively into the shared target/. Every later demo reuses that build, and opens in seconds rather than minutes. If bb doctor says your jank can't start, point JANK at one that can, such as Homebrew's: JANK=/opt/homebrew/opt/jank/bin/jank bb starfield.

A demo runs from its own directory, which is where its asset paths (../jank-raylib-sys/raylib/examples/...) resolve against the repo's raylib submodule.
They were split out of raylib-jnk, which keeps the guide to jank's C++ interop that explains how they're written. All but one are ports of raylib's own example programs, and each demo's page names the original. The NOTICE file carries the licence terms.
