[CHALLENGE] Write a program that converts a string to Brainfuck code - Insurmountable - Dec 5, 2016
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

If you want the prize, show your code!

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;
}

And nice challenge, i didn't know about brainfuck !
Helloworld:

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:
Quote: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
Code

I made the solution 15 minutes after learning brainfuck

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