Quick Start

Installation

From Crates.io

cargo install openscript_cli

From Source

git clone https://github.com/openscript-lang/openscript-rs.git
cd openscript-rs
cargo build --release

Your First Script

Create a file hello.os:

#!/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:

openscript run hello.os
