Brain Flak Macro

Write Brain-Flak code inside rust. You can pass a vector for input. The brain_flak macro will expand to stack manipulation.

use brain_flak_macro::brain_flak;

let mut vec: Vec<i32> = vec![20, 5];
brain_flak! { &mut vec =>
    // multiplication
    ([({}<([({}(<()>))<>](<()>))<>>)<>]){({}[()]<(({})<({}{})>)>)<>}{}{}<>{}{}{}<>
}
assert_eq!(vec![100], vec);

Why

I was about to make brainfuck macro but it already exist. A random guy from some random discord server suggested Brain-Flak instead. It's choice of using balanced brackets make it easy enough for just using macro_rules (No).

lib.rs:

Stack manipulation with Brain-Flak.

use brain_flak_macro::brain_flak;

let mut vec = vec![20, 5];
brain_flak! { &mut vec =>
    // multiplication
    ([({}<([({}(<()>))<>](<()>))<>>)<>]){({}[()]<(({})<({}{})>)>)<>}{}{}<>{}{}{}<>
}
assert_eq!(vec![100], vec);
