Syntax: The main function

● Beginner3 min

A program starts at fn main(). In a single-file script, the lines at the top level are main.

fn main() {
    greet("Asha")
    greet("Ravi")
}

fn greet(name: String) {
    print("Hello, {name}")
}

kavach run main.kav

Hello, AshaHello, Ravi

main calls greet although greet is written below it: functions and types can be used anywhere in their file. Local variables are different: they exist only from their line on.

Scripts

For a quick script, leave main out. The lines at the top level become its body:

print("Hello, Kavach!")
const year = 2026
print("Written in {year}")

kavach run script.kav

Hello, Kavach!Written in 2026
