Hello World

Create hello.wyn:

fn main() {
    println("Hello from Wyn! 🐉")
}

Run it:

wyn run hello.wyn

Output:

Hello from Wyn! 🐉

What's Happening

1. wyn run transpiles your .wyn file to C
2. Compiles the C with your system compiler
3. Runs the resulting binary

For a compiled binary:

wyn build hello.wyn -o hello
./hello

Try It

🐉 Playground

fn greet(name: string = "World") { println("Hello, ${name}! 🐉") } fn main() { greet() greet("Wyn") var names = ["Alice", "Bob", "Charlie"] for name in names { greet(name) } }
