Unnarize

A high-performance bytecode interpreter for a dynamic, C-style scripting language with "Gapless" Generational Garbage Collection and native Async/Await support.

What is Unnarize?

Unnarize is a modern scripting language designed for speed, reliability, and ease of use. It compiles source code to bytecode and executes it on a high-performance virtual machine featuring:

Computed Goto Dispatch – Extremely fast instruction dispatching (GCC/Clang extension)
Generational GC – Separates short-lived objects (Nursery) from long-lived ones (Old Gen) for minimal pause times
Concurrent Marking & Parallel Sweeping – Background garbage collection without "Stop-The-World" freezes
Zero External Dependencies – Pure C implementation using only standard libc and pthreads

Key Features

High Performance

Achieves ~275 million ops/sec on loop benchmarks. Optimized bytecode VM with specialized opcodes for common operations.

Gapless GC

Production-grade generational garbage collector with concurrent marking and parallel sweeping. No more STW pauses.

Async/Await

First-class support for non-blocking concurrency with async functions, await expressions, and native event loop.

Module System

Hierarchical imports with relative path resolution. Organize code into reusable modules.

Rich Standard Library

7 built-in core libraries: HTTP server, JSON, web scraper, string manipulation, file I/O, timers, and UON database.

Clean Syntax

Familiar C-style syntax with modern touches. Easy to learn if you know JavaScript, C, or Java.

Quick Example

// Hello World
var name = "Unnarize";
print("Hello, " + name + "!");

// Function
function factorial(n) {
    if (n <= 1) return 1;
    return n * factorial(n - 1);
}
print(factorial(10)); // 3628800

// HTTP Server
function handleApi(req) {
    return "{\"status\":\"ok\"}";
}
ucoreHttp.route("GET", "/api", "handleApi");
ucoreHttp.listen(8080);
