🚀 BN Script v0.1.0 Alpha — First Public Compiler Release

BN Script is an automation-first programming language that compiles to JavaScript.

Today marks the first public alpha release of BN Script, featuring a complete compiler pipeline, runtime system, command-line interface, and function support.

This release focuses on building a solid foundation for future language features while keeping the architecture simple, testable, and extensible.

✨ What's Included

Compiler Pipeline

BN Script now includes a complete compiler frontend:

  • Lexer
  • Parser
  • Abstract Syntax Tree (AST)
  • Semantic Analyzer
  • JavaScript Generator

Runtime

Built-in runtime helpers:

  • File Operations
  • Environment Variables
  • HTTP Requests
  • Wait/Sleep Utilities
  • Runtime Error Handling

CLI

Validate, build, and run BN Script programs directly from the command line.

bn check app.bn
bn build app.bn
bn run app.bn

🏗 Architecture

BN Script follows a real compiler architecture:

BN Script Source
        ↓
      Lexer
        ↓
      Parser
        ↓
 Semantic Analyzer
        ↓
 JavaScript Generator
        ↓
      Runtime
        ↓
        CLI

Unlike simple transpilers based on string replacement, BN Script uses structured parsing and semantic analysis before generating JavaScript.
