Welcome to Jabline

A compiled, cloud-native programming language with a custom bytecode virtual machine.

Jabline is a modern, general-purpose programming language designed for the cloud era. It combines the clean, familiar syntax of JavaScript/TypeScript with the powerful concurrency model of Go and the performance of a custom bytecode Virtual Machine (JBVM).

• Fast Execution: Compiles directly to bytecode, bypassing slow tree-walking interpretation.
• True Concurrency: Native support for spawn and channels (CSP model) for effortless multi-threading.
• Batteries Included: Ships with an LSP server, code formatter, package manager (JPM), and test runner out of the box.
• Modern Syntax: Generics (<T>), optional typing, pipe operators (|>), and robust error handling.
• Built for the Web: Native standard libraries for HTTP, WebSockets, JSON, and Cryptography.

• Jabline: The core compiler, Virtual Machine (JBVM), and CLI toolchain. Start here!
• Registry: The official package registry for the Jabline Package Manager (JPM).
• VS Code Extension: Full IDE support with syntax highlighting, autocompletion, and diagnostics.

import { NewRouter, ListenAndServe } from "std/net/http";

// Create a concurrent background task
spawn fn() {
    let data = heavyComputation();
    echo("Background task finished!");
}();

// Setup a simple REST API
let srv = NewRouter();

srv.get("/ping", fn(ctx) { 
    return ctx.text("Pong!", 200); 
});

ListenAndServe(8080, srv);
