**Bootstrap infrastructure and educational resource supporting the [Ruchy programming language](https://github.com/paiml/ruchy) ecosystem.** While the main Ruchy project has achieved [actual self-hosting](https://github.com/paiml/ruchy/blob/main/SELF_HOSTING_ACHIEVEMENT.md), RuchyRuchy provides educational examples, development tools, and performance validation for learning compiler construction concepts.

> **🏆 IMPORTANT**: The main [Ruchy project](https://github.com/paiml/ruchy) achieved **real self-hosting** in August 2025. This project serves as **bootstrap infrastructure and education** to support that ecosystem.

## 🎯 **Project Purpose: Bootstrap Education & Tooling**

**Objective**: Provide educational resources and development tools for understanding how bootstrap compilers work, complementing the production Ruchy compiler with:

```
Educational Stages:
├── Stage 0 (Lexer)     → Learn tokenization concepts
├── Stage 1 (Parser)    → Understand AST construction  
├── Stage 2 (TypeCheck) → Explore type inference (Algorithm W)
└── Stage 3 (CodeGen)   → Master code generation techniques
```

**Value Proposition**: Learn compiler construction through working implementations while supporting the Ruchy ecosystem with development tools and performance validation.

## 🚀 Quick Start

### Install via Cargo (Recommended)

```bash
# Install the debugging toolkit
cargo install ruchyruchy

# Validate debugging tools
ruchydbg validate
```

### Install from Source

```bash
# Install the production Ruchy compiler (required)
cargo install ruchy

# Clone the educational bootstrap project
git clone https://github.com/pragmatic-ai-labs/ruchyruchy.git
cd ruchyruchy

# Build and install
cargo build --release
cargo install --path .

# Explore educational examples
make stage0-demo      # Learn tokenization
make performance-demo # See code generation benchmarks
make concepts-demo    # Understand bootstrap principles
```

## ✨ Educational Architecture

### 📚 Learning-Focused Design

**Design Principle**: Demonstrate compiler construction concepts through progressive stages, with each stage teaching different aspects of compilation while supporting the main Ruchy ecosystem.

| Stage | Educational Focus | Implementation | Learning Outcome |
|-------|------------------|----------------|------------------|
| **Stage 0** | Tokenization | Working lexer | Understand lexical analysis |
| **Stage 1** | Parsing | AST construction | Learn syntax analysis |  
| **Stage 2** | Type Systems | Algorithm W concepts | Explore type inference |
| **Stage 3** | Code Generation | Ruchy→Rust tools | Master compilation |
