Awesome Lists containing this project
- awesome-programming-languages - Jank - Jank is a Clojure dialect which aims to offer the best of both worlds: dynamic and static. For both of these worlds, jank uses a single runtime, so the transition from one to the other is not only seamless, it can be gradual. (Uncategorized / Uncategorized)
README
# What is jank?
Most simply, jank is a [Clojure](https://clojure.org/) dialect on LLVM with C++ interop.
Less simply, jank is a general-purpose programming language which embraces the interactive,
functional, value-oriented nature of Clojure and the desire for the native
runtime and performance of C++. jank aims to be strongly compatible with
Clojure. While Clojure's default host is the JVM and its interop is with Java,
jank's host is LLVM and its interop is with C++.
For the current progress of jank and its usability, see the tables here: https://jank-lang.org/progress/
The current tl;dr for jank's usability is: **still getting there, but not ready for
use yet. Check back in a few months!**
## Latest binaries
There are pre-compiled binaries for Ubuntu 24.10, which are built to follow the
`main` branch. You can download a tarball with everything you need here: https://github.com/jank-lang/jank/releases/tag/latest
## Appetizer
```clojure
; Comments begin with a ;
(println "meow") ; => nil
; All built-in data structures are persistent and immutable.
(def george {:name "George Clooney"}) ; => #'user/george
; Though all data is immutable by default, side effects are adhoc.
(defn say-hi [who]
(println (str "Hi " (:name who) "!"))
(assoc who :greeted? true))
; Doesn't change george.
(say-hi george) ; => {:name "George Clooney"
; :greeted? true}
; Many core functions for working with immutable data.
(apply + (distinct [12 8 12 16 8 6])) ; => 42
; Interop with C++ can happen *seamlessly*.
(defn sleep [ms]
(let [duration (c++/std.chrono.milliseconds ms)]
(c++/std.this_thread.sleep_for duration)))
