Native Clojure
Hand-crafted compiler
Unprecedented C++ interop
jank is Clojure on top of C++. It has C++ interop unlike any other language. Templates, virtual functions, exceptions, overload resolution, and RAII all just work in jank. No boilerplate necessary. Just include your headers and go!
jank is a robust Clojure dialect. It offers interactive REPL-driven development powered by a Clang-based C++ JIT compiler.
(ns my.app.filesystem
(:include "boost/filesystem.hpp")
(:refer-global :rename {boost.filesystem.file_size file-size}))
(defn file-info [file-path]
(try
(let [bytes (file-size (cpp/cast std.string file-path))]
{:path file-path
:size bytes})
(catch boost.filesystem.filesystem_error e
{:path file-path
:error (.what e)})))
(file-info "/etc/passwd")
; {:path "/etc/passwd", :size 4025}
(file-info "/root/.bash_history")
; {:path "/root/.bash_history"
; :error "boost::filesystem::file_size: Permission denied [system:13]: \"/root/.bash_history\""}
jank builds upon Clojure
Keep your existing code; unlock the native world.
jank is Clojure
jank is a full-on Clojure dialect, with C++ interop instead of Java interop. There's a :jank reader conditional for when you need it.
jank is C++
jank can include any C++ source, link to any C or C++ library, and it uses the C++ type system. jank even compiles to C++!
Cargo-inspired tooling
jank uses Leiningen-based project management and has a rich native build system. It's easy to add C and C++ dependencies to your project.
REPL and native JIT compiler
Use your favorite nREPL editor plugin. jank contains an LLVM-based JIT runtime to compile C++ code on the fly.
jank's error messages are beautiful
Find your mistakes more easily and look good while doing it.
Trace your code through macros
jank's compiler will provide macro usage context and can re-trace source information to ensure you always get the best error possible.
Reimagined C++ errors
jank improves upon traditional Clang/GCC error messages for C++ interop, so writing C++ from jank feels even better than just writing normal C++.
