PseudoBF

PseudoBF is simple language, that compiles to brainfuck itself. That is, you can write simple code similar to that:

function compare(varA, varB) {
     if (varA == varB) {
         print("equal. ");
     } else { 
         print("not equal. ");
     }
}

function main() : locals(a, b, c) {
    a = 7;

    print("Compare a to 5: ");
    compare(a, 5);

    print("Compare a to 7: ");
    compare(a, 7);
}

And feed it into PseudoBF compiler, to get equivalent code... In brainfuck!

After executing above code in any brainfuck interpreter, we get expected optput:

Compare a to 5: not equal. Compare a to 7: equal.
