How does the C++ interop work in Jank?

It uses a specialized cpp/ namespace and macros like #cpp to allow direct access to C++ functions, types, and libraries with compile-time type resolution and minimal overhead.

Jank is a native dialect of Clojure that compiles to LLVM IR, offering high performance, small binary sizes, and deep C++ integration without the JVM.

Can I use Jank for existing Clojure projects?

While Jank shares high syntax parity (93%) with Clojure, it is designed for native environments. It uses module paths instead of classpaths and does not support JVM-specific features.

What are the performance benefits of using Jank?

By compiling to LLVM IR, Jank achieves native execution speeds, eliminates reflection, and allows for Ahead-of-Time (AOT) compilation, making it significantly faster than interpreted Clojure for many tasks.

Developer Tools

Compiles Clojure to LLVM IR with seamless C++ interoperability for high-performance native applications.

Jank provides a native Clojure experience by compiling directly to LLVM IR, enabling developers to build high-performance binaries without JVM overhead. It offers a sophisticated C++ interop system that allows for direct calls to C++ functions, use of templates, and integration with existing native libraries while maintaining Clojure's functional paradigms and REPL-driven development. Based on SICP theoretical foundations, Jank is ideal for systems programming, performance-critical modules, and projects requiring deep integration with the C++ ecosystem.
