## Quick Start

### Installation

#### From Crates.io
```bash
cargo install openscript_cli
```

#### From Source
```bash
git clone https://github.com/openscript-lang/openscript-rs.git
cd openscript-rs
cargo build --release
```

### Your First Script

Create a file `hello.os`:

```openscript
#!/usr/bin/env openscript

echo "Hello, OpenScript!"

# Variables and operations
let name = "Developer"
let greeting = "Welcome to OpenScript, " + name + "!"
echo greeting

# Functions
fn fibonacci(n) {
    if n <= 1 {
        return n
    } else {
        return fibonacci(n - 1) + fibonacci(n - 2)
    }
}

echo "Fibonacci(10): " + fibonacci(10)

# HTTP requests
let response = http_get("https://api.github.com/users/octocat")
if response.status == 200 {
    let user = json_parse(response.body)
    echo "GitHub user: " + user.name
}

# AI integration (requires OPENAI_API_KEY)
if env_get("OPENAI_API_KEY") != null {
    let ai_response = ai_complete("Explain the benefits of automation in software development")
    echo "AI says: " + ai_response
}
```

Run the script:
```bash
openscript run hello.os
```

## Language Guide

### Variables and Types

```openscript
# Numbers
let age = 25
let pi = 3.14159

# Strings
let name = "OpenScript"
let multiline = """
This is a
multiline string
"""

# Booleans
let is_awesome = true
let is_ready = false

# Arrays
let numbers = [1, 2, 3, 4, 5]
let mixed = ["hello", 42, true, null]

# While loops
let count = 0
while count < 5 {
    echo "Count: " + count
    count = count + 1
}
```

### Functions

```openscript
# Basic function
fn greet(name) {
    return "Hello, " + name + "!"
}

# Function with multiple parameters
fn calculate_area(width, height) {
    return width * height
}

# Higher-order functions
fn apply_operation(x, y, operation) {
    return operation(x, y)
}

let add = fn(a, b) { return a + b }
let result = apply_operation(5, 3, add)  # Returns 8
```

### AI Integration

# Simple completion
let response = ai_complete("Write a function to sort an array")
echo response

# Code generation
let code = ai_complete("Generate a Python function that reads a CSV file and returns a list of dictionaries")
write_file("generated_code.py", code)

# Text analysis
let text = "OpenScript is an innovative scripting language with AI capabilities."
let analysis = ai_complete("Analyze the sentiment and key themes in this text: " + text)
echo analysis
```

### HTTP and API Integration

```openscript
# GET request
let response = http_get("https://api.github.com/users/octocat")

    echo "Repos: " + data.public_repos
}

# POST request
let post_data = {
    "title": "Hello World",
    "body": "This is a test post",
    "userId": 1
}

let post_response = http_post(
    "https://jsonplaceholder.typicode.com/posts",
    json_stringify(post_data),
    {"Content-Type": "application/json"}

    }
}
```

    assert(contains(lower(validation), "valid"))
}
```

### Infrastructure Monitoring
```openscript
# Monitor system health with AI-powered alerts
let metrics = get_system_metrics()
