Introduction to White Language

White Language is a programming language that pursues the "safety of ARC" combined with the "precision of C."

We are committed to resolving the conflict between memory safety and low-level control in systems programming. Through our proprietary Automatic Reference Counting (ARC) mechanism, White Language provides a near-memory-safe development experience without the overhead of Garbage Collection (GC).

Core Features​

  • Deterministic Memory Management: Based on compiler-injected reference counting, the timing of memory deallocation is entirely predictable.
  • Extreme C Compatibility: Call the C standard library directly by declaring extern without the need for complex wrappers.
  • Self-Hosting Compiler: The White Language compiler, wlc, is written in White Language itself.
  • LLVM Backend: Generated code is deeply optimized by LLVM, delivering native performance.

Quick Preview​

Here is a simple White Language program:

import "builtin"

func main() -> Int {
    let message -> String = "Hello White Language World!";
    builtin.print(message);
    return 0;
}
