NIL Zonefile

A Rust library for parsing and creating NIL zonefiles. This library supports both WebAssembly and native Rust environments.

Installation

Add this to your Cargo.toml:

[dependencies]
nil-zonefile = "0.1.0"

For WebAssembly support, enable the wasm feature:

[dependencies]
nil-zonefile = { version = "0.1.0", features = ["wasm"] }

Usage

Rust

use nil_zonefile::ZoneFile;
fn main() -> Result<(), serde_json::Error> {
// Parse a zonefile
let json_str = r#"{
"zonefile": {
"owner": "SP3D03X5BHMNSAAW71NN7BQRMV4DW2G4JB3MZAGJ8",
"general": "Example Name",
"twitter": "@example",
"url": "example.locker",
"nostr": "",
"lightning": "",
"btc": "bc1..."
}
}"#;
let zonefile = ZoneFile::from_str(json_str)?;
// Convert back to JSON
let output = zonefile.to_string()?;
Ok(())
}

JavaScript/TypeScript (via WebAssembly)

=

import { ZoneFile } from 'nil-zonefile';

const zonefile = ZoneFile.fromString(jsonString);
const output = zonefile.toString();

Rust CBOR Support

use nil_zonefile::ZoneFile;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Read from CBOR
    let cbor_bytes: &[u8] = &[0u8; 0];  // example empty CBOR data
    let zonefile = ZoneFile::from_cbor(cbor_bytes)?;

    // Write to CBOR
    let output_bytes: Vec<u8> = zonefile.to_cbor()?;
    Ok(())
}

JavaScript CBOR Support

import { parse_zonefile_cbor, create_zonefile_cbor } from 'nil-zonefile';

// Read from CBOR
const cborBytes = new Uint8Array(/* your CBOR data */);
const result = parse_zonefile_cbor(cborBytes);

// Write to CBOR
const output = create_zonefile_cbor(cborBytes);

Generate Zonefile

import { generateZonefile } from 'nil-zonefile';

const zonefile = {
    zonefile: {
        owner: "SP3D03X5BHMNSAAW71NN7BQRMV4DW2G4JB3MZAGJ8",
        general: "Example Name",
        twitter: "@example",
        url: "example.locker",
        nostr: "",
        lightning: "",
        btc: "bc1...",
        subdomains: {}
    },
    version: "1.0.0",
    status: "current"
};

// Generate uncompressed CBOR
const bytes = generateZonefile(zonefile);

// Generate compressed CBOR using zstd compression
const compressedBytes = generateZonefile(zonefile, true);

Building on macOS

When building this project on macOS (especially for WebAssembly), you need LLVM installed and configured correctly. Two options are available:

Option 1: Using the Setup Script

Run the provided setup script:

source ./setup-llvm.sh

This script will:

1. Check if you're on macOS
2. Install LLVM via Homebrew if needed
3. Set up the required environment variables

Option 2: Manual Setup

1. Install LLVM if you haven't already:

   brew install llvm

2. Set up the required environment variables:

   export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
   export CC=/opt/homebrew/opt/llvm/bin/clang
   export AR=/opt/homebrew/opt/llvm/bin/llvm-ar

   To make these changes permanent, add the above lines to your ~/.zshrc or ~/.bash_profile.
