Nλvescript (NaveScript)

Author: Evan Shipley

A universal, polyglot coding language and interpreter built for performance and portability. Nλvescript is the "Universal Omni-Language," designed to bridge multiple languages, capabilities, and hardware targets under a single, highly-optimized runtime.

🌍 Code Translation & Interop

Nλvescript features a unique Polyglot Transmutation Engine that allows it to translate, execute, and verify code from multiple languages:

• Supported Languages: Python, JavaScript, Ruby, Bash, Perl.
• Transmutation Loop:
  1. Translate: Accepts foreign language source code.
  2. Execute: Runs foreign code in a sandboxed environment.
  3. Transmute: Converts the foreign output/state into Nλvescript's native JSON representation.
  4. Verify: Runs native Nλvescript operations (addition, string manipulation, array reversal) against the foreign output to ensure semantic correctness.
  5. Assert: Performs rigorous equality checks (Assertion engine) to guarantee the translation matches the origin behavior.

This cyclic verification loop ensures that Nλvescript-translated code functions exactly as the origin language intended.

• WASI 0.2 (Preview 2): Built on the WebAssembly Component Model for modern, composable binaries.
• Component Model: True "LEGO brick" modularity with rich, language-agnostic types via WIT.
• GraalVM Polyglot: Bridge for zero-copy execution of Python, JavaScript, and Ruby.
• Capability-Based Security: Explicit declaration of required OS permissions at the "World" level.
• High-Performance Runtime: Powered by Wasmtime component-model engine.

🛠 Installation

# Requires Rust and Cargo
git clone https://github.com/naveos/navescript
cd navescript
cargo build --release

🏃 Usage

Run a script (as a Component)

cargo run -- run examples/wasi_test.nave

Compile to WebAssembly Component (WAT)

cargo run -- compile examples/wasi_test.nave --output component.wat

Check Bridge Status

cargo run -- status
