Overview

Bunsenite is a Nickel configuration file parser with a Rust core library and multi-language FFI bindings. It provides a stable C ABI layer (via Zig) that enables bindings for Deno (JavaScript/TypeScript), Rescript, and WebAssembly for browser and universal use.

Key Features

✅ Type Safety: Compile-time guarantees via Rust’s type system
✅ Memory Safety: Rust ownership model, zero unsafe blocks
✅ Offline-First: Works completely air-gapped, no network dependencies
✅ Multi-Language: FFI bindings for Deno, Rescript, and WASM
✅ Standards Compliant: RSR Bronze tier, TPCF Perimeter 3
✅ Well-Documented: Comprehensive API docs, examples, and guides
✅ Production-Ready: 100% test pass rate, CI/CD, semantic versioning

import init, { parse_nickel } from './bunsenite.js';

async function main() {
    await init();

Design Rationale

Zig FFI Layer: Provides stable C ABI, isolating consumers from Rust ABI changes. This allows language bindings to remain stable across Rust compiler versions.

WASM Support: Enables browser deployment and universal compatibility at ~95% native speed.

Deno .ts Files: Required syntax for Deno runtime FFI (NOT plain TypeScript). Uses Deno.dlopen for native FFI calls to Zig layer.
