Example

extern crate brainhug;
use brainhug::Lang;

fn main() {
    // will print `Hello World!`
    let input = "++++++++[>++++[>++>+++>+++>+<<<<-]>+>+>->>+[<]<-]>>.>---.+++++++..+++.>>.<-.<.+++.------.--------.>>+.>++.";

    // `brainhug::generate` will generate a `String`
    println!("{}", brainhug::generate(Lang::C, input));
}

It will produce

#include "stdio.h"

int main() {
    char tape[20000] = {0};
    char *ptr = tape;
        *ptr += 8;
