jank is a general-purpose programming language which embraces the interactive, functional, value-oriented nature of Clojure, the desire for native compilation and minimal runtimes of C++, and the gradual, structural typing of languages like TypeScript. 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++ or LLVM IR.
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: not usable for anything useful.
For Debian-based distros, this should be all you need:
$ sudo apt-get install -y curl git zip build-essential entr libssl-dev libdouble-conversion-dev pkg-config ninja-build python3-pip cmake debhelper devscripts gnupg zlib1g-dev clang-14
For macOS, try this:
$ brew install curl git zip entr openssl double-conversion pkg-config ninja python cmake gnupg zlib llvm@14
Clone the repo as follows:
$ git clone --recurse-submodules https://github.com/jank-lang/jank.git
# If you don't recurse submodules when cloning, you'll need to run this.
$ git submodule update --recursive --init

-- For hot reloading tests on save../bin/install
-- For packaging.
Note that, by default, jank will compile Cling/Clang/LLVM for you, as part of
your build directory. This can take an hour or two, depending on your machine.
Building jank itself should take less than a minute. If you want to build it
yourself, or want it outside of jank's build dir, you can use the
bin/build-cling [cling-dir]
script.
If you build your own Cling, or if you get it from somewhere else, you can
provide it to ./bin/configure
by using -Dcling_dir=[cling-dir]/builddir
.
A typical release build just needs the following:
$ ./bin/configure -GNinja -DCMAKE_BUILD_TYPE=Release
$ ./bin/compile
To make a debug build, specify the build type when configuring.
$ ./bin/configure -GNinja -DCMAKE_BUILD_TYPE=Debug -Djank_tests=on
$ ./bin/compile
$ ./bin/watch-tests
There's also a script for installing jank and all its necessary dependencies. Note that this includes a lot of header files, which are necessary for jank's JIT compilation.
$ ./bin/configure -GNinja -DCMAKE_BUILD_TYPE=Release
$ ./bin/install
