# Parse Go to PW
python3 -c "from reverse_parsers.cli import main; main(['main.go', '--output', 'service.pw'])"

# Parse ANY language to PW
python3 -c "from reverse_parsers.cli import main; main(['code.rs', '--output', 'translated.pw'])"

# Then generate to ANY other language
promptware build translated.pw --lang python
```

```bash
# Build - Compile PW to target language
promptware build calculator.pw --lang python -o calculator.py
promptware build api.pw --lang go -o main.go
promptware build service.pw --lang rust -o lib.rs

# Compile - Generate MCP JSON (for AI agents)
promptware compile agent.pw -o agent.json

# Run - Execute PW directly
promptware run calculator.pw

# Version
promptware --version
```

---

## 📚 Use Cases

### 1. Polyglot Migration
**Problem**: Slow Python service needs Go's performance
**Solution**: Instant translation

```bash
python3 -c "from reverse_parsers.cli import main; main(['slow_service.py', '--output', 'service.pw'])"
promptware build service.pw --lang go -o service.go
# Deploy Go version → 10x faster
```

### 2. Team Collaboration
**Problem**: Python dev and Go dev can't share specifications
**Solution**: Use PW as universal intermediate

```bash
# Go dev writes spec in PW
go-dev$ cat > api_spec.pw
# Python dev generates Python server
python-dev$ promptware build api_spec.pw --lang python
# Go dev generates Go client
go-dev$ promptware build api_spec.pw --lang go
```

### 3. Code Analysis
**Problem**: Need static analysis for multiple languages
**Solution**: Parse all to PW, analyze once

```bash
# Parse different codebases to PW
python3 -c "from reverse_parsers.cli import main; main(['service1.py', '--output', 'ir1.pw'])"
python3 -c "from reverse_parsers.cli import main; main(['service2.go', '--output', 'ir2.pw'])"
# Analyze universal IR
your-analyzer ir1.pw ir2.pw
```

### 4. AI Agent Communication
**Problem**: AI agents need to read and modify code in multiple languages
**Solution**: Agents work in PW, compile to target

```bash
# Agent reads Python code
agent$ python3 -c "from reverse_parsers.cli import main; main(['user_code.py', '--output', 'analyzed.pw'])"
# Agent suggests changes in PW (universal)
agent$ cat > improved.pw
# Compile back to Python
agent$ promptware build improved.pw --lang python
```

## 🏗️ Architecture

![Promptware Architecture](docs/images/architecture-diagram.svg)

### How It Works

1. **Native AST Parsers** (66K-40K LOC each)
   - Language-specific AST analysis
   - Type inference
   - Semantic extraction

2. **PW Intermediate Representation**
   - Universal IR preserving semantics
   - Type-safe
   - Language-agnostic

3. **Code Generators** (34K-58K LOC each)
   - Idiomatic output per language
   - Production-hardening features
   - MCP protocol integration

**Result**: Parse ANY → Translate semantics → Generate ANY

## ✨ Features

### 🔄 Universal Cross-Language Translation

**Promptware is the only framework that enables true bidirectional code translation across 5 languages.**

Not just code generation - **universal translation:**

```bash
# Parse ANY language to PW DSL (auto-detects language from file extension)
python3 reverse_parsers/cli.py server.py              # Python → PW
python3 reverse_parsers/cli.py server.js              # Node.js → PW
python3 reverse_parsers/cli.py main.go                # Go → PW
python3 reverse_parsers/cli.py main.rs                # Rust → PW
python3 reverse_parsers/cli.py Program.cs             # C# → PW

# Save to file
python3 reverse_parsers/cli.py server.py --output agent.pw

# Cross-language translation (parse → modify lang → generate)
python3 reverse_parsers/cli.py server.py --output temp.pw  # Python → PW
sed -i '' 's/lang python/lang go/' temp.pw                 # Change to Go
promptware generate temp.pw --lang go                       # PW → Go
```

**Translation Matrix** (20 combinations - 100% success rate):

|          | → Python | → Node.js | → Go | → Rust | → .NET |
|----------|----------|-----------|------|--------|--------|
| **Python**   | -    | ✅       | ✅   | ✅     | ✅     |
| **Node.js**  | ✅   | -        | ✅   | ✅     | ✅     |
| **Go**       | ✅   | ✅       | -    | ✅     | ✅     |
| **Rust**     | ✅   | ✅       | ✅   | -      | ✅     |
| **.NET**     | ✅   | ✅       | ✅   | ✅     | -      |

**Use Cases:**
- **Polyglot Migration** - Move services from Python to Go without rewriting
- **Team Collaboration** - Go dev and Python dev communicate via PW
- **API Documentation** - Parse any codebase to human-readable spec
- **Code Analysis** - Universal IR for static analysis tools
- **Agent Communication** - AI agents read ANY language, discuss in PW

---

### PW Native Language Syntax (NEW!)

**PW is now a true programming language with C-style syntax:**

```pw
// Modern C-style syntax with type annotations
function add(x: int, y: int) -> int {
    return x + y;
}

function divide(numerator: int, denominator: int) -> float {
    if (denominator != 0) {
        return numerator / denominator;
    } else {
        return 0.0;
    }
}

function calculate() -> int {
    let numbers = [1, 2, 3, 4, 5];
    let total = 0;

    for (num in numbers) {
        total = total + num;
    }

    return total;
}

// Classes with constructors
class Calculator {
    result: float;

    constructor(initial_value: float) {
        self.result = initial_value;
    }

    function add(value: float) -> void {
        self.result = self.result + value;
    }

    function get_result() -> float {
        return self.result;
    }
}
```

**Language Features:**
- ✅ C-style function syntax: `function name(params) -> type { body }`
- ✅ Modern control flow: `if (condition) { }`, `else { }`, `for (x in items) { }`
- ✅ Type annotations: `x: int`, `name: string`, `active: bool`
- ✅ Multiple comment styles: `//`, `/* */`, `#`
- ✅ Classes with constructors and methods
- ✅ Arrays: `[1, 2, 3]`, Maps: `{key: "value"}`
- ✅ Optional semicolons (both `return x;` and `return x` work)

**Compile to any language:**
```bash
# Compile to Python
promptware build calculator.pw --lang python -o calculator.py

# Compile to Go
promptware build calculator.pw --lang go -o calculator.go

# Compile to Rust
promptware build calculator.pw --lang rust -o calculator.rs

# Execute directly
promptware run calculator.pw
```

**Complete specification**: See [`docs/PW_NATIVE_SYNTAX.md`](docs/PW_NATIVE_SYNTAX.md)

### New Language Features (v2.1.0b3)

**For Loops** ✅ Working
```pw
// C-style for loops
for (let i = 0; i < 10; i = i + 1) {
    // Loop body
}

// For-in loops
for (item in items) { }
for (i in range(0, 10)) { }
for (index, value in enumerate(items)) { }
```

**While Loops** ✅ Working
```pw
while (condition) {
    if (should_skip) {
        continue;  // Skip to next iteration
    }
    if (should_stop) {
        break;     // Exit loop
    }
}
```

**Try/Catch** ✅ Working
```pw
try {
    let result = risky_operation();
    return result;
} catch (error) {
    return default_value;
} finally {
    cleanup();  // Always runs
}
```

**Arrays** ✅ Working
```pw
let numbers = [1, 2, 3, 4, 5];
numbers[0] = 10;
let count = numbers.length;  // Array length property
```

**Maps/Dictionaries** ✅ Working (Safe Access)
```pw
let user = {
    name: "Alice",
    age: 30,
    email: "alice@example.com"
};

// Safe map access - returns null if key missing (no exceptions!)
if (user["name"] != null) {
    let name = user["name"];
}
```

**Optional Types** ✅ Working
```pw
// Function returning optional (nullable) map
function find_user(id: int) -> map? {
    if (id < 0) {
        return null;  // Valid for optional types
    }
    return {id: id, name: "User"};
}

// Optional parameters
function greet(name: string?) -> string {
    if (name != null) {
        return "Hello, " + name;
    }
    return "Hello, Guest";
}
```

**Classes** ✅ Working
```pw
class User {
    name: string;
    age: int;

    constructor(name: string, age: int) {
        self.name = name;
        self.age = age;
    }

    function greet() -> string {
        return "Hello, " + self.name;
    }
}
```

        "endpoint": "https://api.example.com/users",
        "method": "GET"
      }
    }
  }'

# Or use the testing framework
promptware test http://localhost:3000 --auto
```

### 6. Use SDK

**Python:**
```python
from promptware.sdk import Agent

agent = Agent("http://localhost:3000")

# Health check
health = agent.health()
print(health)  # {'status': 'alive', 'uptime_seconds': 3600}

# Call verbs
result = agent.api.call(
    endpoint="https://api.example.com/users",
    method="GET"
)
print(result)
```

**Node.js:**
```javascript
import { Agent } from '@promptware/client';

const agent = new Agent('http://localhost:3000');

// Health check
const health = await agent.health();
console.log(health);

// Call verbs
const result = await agent.api.call({
  endpoint: 'https://api.example.com/users',
  method: 'GET'
});
console.log(result);
```

## 💡 Why Promptware?

**Choose Promptware when you need:**
- **Universal code translation** - The ONLY framework that translates code bidirectionally across 5 languages (20 combinations, 100% success rate)
- **Polyglot migration** - Move existing services from Python to Go, Node.js to Rust, etc. without manual rewriting
- **Cross-language collaboration** - Teams using different languages communicate via PW as a universal protocol
- **Production quality by default** - Error handling, health checks, rate limiting, security headers, and observability without configuration
- **Rapid prototyping** - Go from idea to running server in 5 minutes with 17.5x code amplification
- **Enterprise-grade SDKs** - Circuit breakers, retry logic, and connection pooling out of the box
- **MCP-native architecture** - First-class support for Model Context Protocol, perfect for AI agent systems

**Consider alternatives when:**
- You need a complex custom protocol (not JSON-RPC/MCP)
- You're building a monolithic application (not microservices)
- You require language-specific optimizations that don't fit the generated patterns
- Your team needs complete control over every line of server code

**Promptware vs Alternatives:**
- **vs OpenAPI/Swagger** - Promptware generates complete production servers with middleware AND parses existing code back to spec (bidirectional)
- **vs gRPC** - MCP protocol is simpler (JSON-RPC) and includes AI agent primitives; use gRPC for high-performance internal services
- **vs Manual coding** - 17.5x faster development with consistent patterns across languages and automatic test generation
- **vs All code generators** - Promptware is the ONLY tool with bidirectional translation - parse ANY language, generate ANY language
