Try RUDRA

Playground

Browse real RUDRA programs and the output they actually produce. Each sample below was compiled and run with the RUDRA 1.1.0 toolchain.

How this works

RUDRA compiles to native machine code, so there is no in-browser compiler. This page shows verified sample programs and their recorded output. To run your own code, install the toolchain and use rudra file.rux program and then run ./program. Nothing here is simulated: the output shown is the real output of each sample.

hello.rux

fn main() -> int {
    print("Hello, RUDRA!\n");
    return 0;
}
return main();

Output (verified)

Hello, RUDRA!

factorial.rux

fn factorial(n: int) -> int {
    if n <= 1 {

    return n * factorial(n - 1);
}
fn main() -> int {
    print(to_str(factorial(5)) + "\n");
    return 0;
}
return main();

struct.rux
