Here's a first glimpse at C++ context being added to errors. In this case, we're noting the candidates involved in ambiguous overload resolution. Thoughts?

Kyle Cesare cooked up a 4x4 sandbox in jank + #raylib + #box3d. It's adorable!

Did you know jank has a built-in benchmarking library for easy benchmarks with beautiful output? It even checks for common benchmarking mistakes, like debug builds, missing optimization flags, and lazy compilation.

jank's terminal REPL client has been revamped to support completions, syntax highlighting, and multi-line inputs. The jank command will now start up the REPL client by default.

Joseph Ferano whipped up a sand painting app with jank and raylib in a matter of hours. It's beautiful!

jank's getting support for runtime exception stack traces and code snippets. This is some tricky code involving LLVM, the GDB-JIT interface, cpptrace, and some jank-side object file tracking. The result is gorgeous. Check out the stack trace for how we can render Clojure frames.

If you've not yet signed up for #clojure Conj, now's a great time. In case you're unable to make it this year, did you know that there's a free live stream? That's right, you can still catch my talk live, for free! 2026.clojure-conj.org

The mantra that I use for basically all of my software development is Kent Beck's "Make it work. Make it right. Make it fast." First we hack together a solution to solve the problem. Then we iterate to clean up the mess and make it maintainable. Then, as needed, we optimize.

Hey folks! I'm happy to share that I'll be presenting at #clojure Conj 2026. My talk "Would you believe it's jank?" will highlight jank's features, go deep into our world-class C++ interop, our custom build system, and include some impressive demos. I'll see you there!

Based on the recent survey, it's pretty clear how people want to use jank. jank will start an era of #clojure game development.

There's now a Github action to set up jank for Ubuntu and macOS! github.com/marketplace/...

We have folks embedding jank in Godot now. Seems like it might be time to prioritize making this easy.

I've been working on jank's ability to compile #clojure programs to native executables which don't depend on Clang/LLVM. All functionality is baked in, like Graal native images. It works! They're smaller than native images and startup is instantaneous. 🔥

There's a new optimization post for jank, this time optimizing a pure #clojure ray tracer. Check it out! jank-lang.org/blog/2026-06...

jank now has its own custom IR

The jank compiler has a new super power. With that, we push jank to the limits to see who has the fastest fibonacci in the west.

Did you know that you can now install jank binaries on Ubuntu 24.04 and 24.10 by using jank's apt PPA? They build continuously from CI. github.com/jank-lang/ja...

Thank you, Nubank, for the Github sponsorship! To me, I gather that Nubank is investing in the future of jank because they clearly care about the future of #clojure and its community. I could not be more appreciative. 🩵

I'm happy to announce that I'll be presenting at Clojure Conj 2025. My talk is entitled: "How to stick with your projects, even when they're janky" We'll cover rewrites, building a community, development practices, avoiding burnout, and, of course, jank itself.
