Scala Native is a new ahead-of-time compiler and lightweight managed runtime designed specifically for Scala. Project is currently in pre-release stage. Follow us on twitter to be first to know about upcoming updates.

• Low-level primitives.

  type Vec = CStruct3[Double, Double, Double]
  
  val vec = stackalloc[Vec] // allocate c struct on stack
  !vec._1 = 10.0            // initialize fields
  !vec._2 = 20.0
  !vec._3 = 30.0
  length(vec)               // pass by reference

  Pointers, structs, you name it. Low-level primitives let you hand-tune your application to make it work exactly as you want it to. You're in control.

• Extern objects.

  @extern object stdlib {
    def malloc(size: CSize): Ptr[Byte] = extern
  }
  
  val ptr = stdlib.malloc(32)

  Calling C code has never been easier. With the help of extern objects you can seamlessly call native code without any runtime overhead.

• Instant startup.

  > time hello-native
  hello, native!
  
  real    0m0.005s
  user    0m0.002s
  sys     0m0.002s
  

  Scala Native is compiled ahead-of-time via LLVM. This means that there is no sluggish warm-up phase that's common for just-in-time compilers. Your code is immediately fast and ready for action.
