Kyna programming language

Readable code. Explicit types. One practical CLI.

Learn the language, run examples, and inspect every compiler stage—from source tokens to HIR, MIR, bytecode, and the virtual machine.

$npm install --global @kyna-language/cli@preview

Recommended. Requires Node.js 18 or newer.

Documentation

Choose a clear path

Start with a guided lesson, or go directly to the reference you need.

Install the CLI, create a project, and run your first Kyna program.

Work through bindings, types, functions, modules, classes, and errors.

Use the reference for syntax, semantics, networking, and async behavior.

Explore text, collections, files, formats, system tools, and timing APIs.

Language

Types can be inferred or written explicitly. State is mutable only when declared with var; const bindings stay immutable.

hello.kynaKyna

fn greet(name: str): str {
    return "Hello, " + name;
}

const language = "Kyna";
print(greet(language));

Validate bindings, types, nullability, calls, and control flow before execution.

Print tokens, syntax trees, HIR, MIR, and bytecode directly from the CLI.

Execute scripts and projects through Kyna’s compiler and runtime pipeline.

Install the preview CLI, create a project, and learn each language feature in order.
