What's up HF, today I have a challenge for you... I know you probably think it's impossible just because you saw the words "Brainfuck". Well guess what? It's actually pretty easy.

Your challenge is to create a function (in any language you like) that takes a string as a parameter and prints out Brainfuck code that will compute that string.

Use this to test your code: https://copy.sh/brainfuck/
How Brainfuck works: https://www.youtube.com/watch?v=-3C200nCwpk

First person to post a working solution gets the prize. Bonus points for having less lines of code (and don't try to shorten code by compressing everything to one line; you must have new lines after semi colons and at least three lines for if-statements, etc.)

Good luck! 🎉

Since I guess nobody can figure it out, I'll post my solution in Go.

Lol, I don't need to buy your program, I've already made my own. It's a challenge.

Lol...the fucking smartphone grammar Dictionary wrote price when I wanted to write "prize" (as you said in #1)

PHP Code


<?php

function toBrainfuck(string $string) {
    $result = '';
    $letters = str_split($string);

    foreach ($letters as $letter) {
        $ascii = ord($letter);
        $result .= str_repeat('+', $ascii) . '.';
        $result .= str_repeat('-', $ascii);
    }

    return $result;
} 


Obviously not the smarted way to do things, but you never said how it should work :p

Nice job, it's a helpful that PHP has a built in function for that.

Ooh, good to see a solution in vanilla C. Nicely done.

Indeed.

Made it a bit shorter cause I can.

PHP Code


<?php

function toBrainfuck($string) {
    $result = '';
    foreach (str_split($string) as $letter) {
        $ascii = ord($letter);
        $result .= str_repeat('+', $ascii) . '.>';
    }
    return $result;
}

Ye but the result is far from optimised haha 😁
And nice challenge, i didn't know about brainfuck !

Next challenge should be the shortest brainfuck string result for a defined word/phrase !

Good idea! Have your program convert this phrase, try to get the shortest result:

Hello, world!

Code:

Code

func v2_convert(s string) {
    ascii := []byte(s)
    for i := 0; i < len(ascii); i++ {
        if i == 0 {
            for j := 0; j < int(ascii[i]); j++ {
                fmt.Print("+")
            }
        } else if ascii[i-1] > ascii[i] {
            for j := 0; j < int(ascii[i-1])-int(ascii[i]); j++ {
                fmt.Print("-")
            }
        } else if ascii[i-1] < ascii[i] {
            for j := 0; j < int(ascii[i])-int(ascii[i-1]); j++ {
                fmt.Print("+")
            }
        }
        fmt.Print(".")
    }
}

Result: 383 chars

Come on now, that's cheating! You have to generate everything programmatically!
