🔤 lncc - Language Node Compiler

lncc is a framework for creating and running your own domain-specific programming languages on top of JavasScript. It allows you to define custom syntax, keyword replacements, and even package handling.

🚀 Features

• 🧠 Simple keyword-to-JS translation (e.g., print → console.log)
• 📦 Auto-import (and auto-install) external packages
• 📁 Custom language file extensions (e.g., .dsl)
• 🛠️ Pluggable and scriptable language behavior
• 🎛️ CLI support for initializing and running projects

📦 Installation

npm install -g lncc

🛠️ Getting Started

1. Initialize a Project

lncc init

Creates:

• lncc.package.json – project manifest
• lncc.config.js – language definition config
• index.dsl – your DSL entry point

2. Define Your Language (lncc.config.js)

const { createLanguage } = require("../");

module.exports = new createLanguage({
  name: "MyLang",
  extension: ".dsl",
  replacements: [
    ['v', 'const'],
    ['print', 'console.log']
  ],
  packages: [
    ['express', 'express']
  ]
});

📄 Example DSL (index.dsl)

v app = express();

app.listen(300, () => {
    print("API running on port 3000");
});

▶️ Run Your Language

lncc

This will parse your DSL, replace keywords, install required packages, and execute the code.

📁 lncc.package.json Format

{
  "name": "example",
  "main": "index.dsl",
  "packages": {
    "express::express": "5.1.0"
  }
}

📚 API: createLanguage(config)

• name: Name of the language.
• extension: Custom file extension for your language files.
• replacements: List of [customSyntax, jsSyntax] keyword pairs.
• packages: Optional list of [customName, nodeModule] for auto-import and install.
