> jank is a general purpose programming language. It’s a dialect of Clojure, which is itself a dialect of Lisp. jank is functional-first, but it supports adhoc mutations and effects. All data structures are persistent and immutable by default and jank, following Clojure’s design, provides mechanisms for safe mutations for easy concurrency. > Beyond Clojure, jank is brethren to C++ and it can reach into C++ arbitraril…

Interesting. The last time I used C++, it was so painful to compile. I love Clojure, though, and a native target is appealing. I wonder how slow the compile/ recompile cycle is in Jank.

JIT compiling C++ is definitely the slowest thing we do. However, we're working on two different codegen modes.

1. C++

2. LLVM IR

The IR is much faster to compile, but its perf isn't nearly as good. This is meant to be a nice trade off, during iteration, so that you can use C++ codegen for your release artifact, but stick with IR when you're REPLing. The IR gen is still unstable right now, for the alpha, but we'll have both solidified this year.

Do you envision the development to track clojure as much as is possible, similar to how cljs was conceived to be clojure in js and not just clojure-ish js, or do you think you'll eventually diverge? I made a language a while ago that was like 90% clojure but hesitated to call it that because I didn't want there to be an expectation that the same code would run as-is in both languages. Seems like from the landing page…

jank is Clojure and will track upstream Clojure development. I'm working closely with the Clojure team and other dialect devs to ensure this remains the case. I am leading a cross-dialect clojure-test-suite to help ensure parity across all dialects: https://github.com/jank-lang/clojure-test-suite We have support or work ongoing for Clojure JVM, ClojureScript, Clojure CLR, babashka, Basilisp, and jank.

With that said, jank will do some trail blazing down other paths (see my other comments here about Carp), but they will be optional modes which people can enable which are specific to jank. Clojure compatibility will remain constant.

Would something like this then be able to interface with Rust codebases?

As much as any C++ project would, yes. That includes either through the C ABI or through the various C++/Rust interop mechanisms.
