PHP 5.5 -> Ruby 2.0 -> Python 2.7 -> Lua -> C # -> Java -> PdfTeX -> GolfScript 855/8 ^ 2 = 13.359375
Gagasan utama adalah:
- Alih-alih benar-benar membuat logika untuk membuat bahasa n +1 di semua bahasa pemrograman lakukan ini hanya satu kali, dan hanya menggunakan fasilitas penulisan acak dan stdout dasar dari setiap bahasa pemrograman
- Untuk mempersingkat generator templat, cukup kompres dengan zLib. Jadikan generator ini bahasa kedua
- Gunakan PHP sebagai bahasa pertama, karena memiliki dekompresor zLib bawaan
Jadi kode awal adalah:
<?php $x=file_get_contents("php://stdin");echo preg_replace_callback("/\[(.*?)\]/",function($m){$r=explode("/",$m[1]);return $r[array_rand($r)];},$x).gzuncompress("BINARY_DATA")."__END__\n".$x;
Di mana BINARY_DATA
versi gzcompressed dari generator template (mis. Hasil dari kode php, yang merupakan versi ruby)
Kode awal lengkap dalam base64 (harus 855 byte setelah decoding):

Catatan
Tampaknya PHP cukup memaafkan dengan data biner dalam string literal, kecuali untuk kode hex AF dan 96. Jangan bertanya mengapa.
Saya mungkin bisa menambahkan perl dan kode C ++ 11 juga dengan mudah (karena keduanya mendukung string string literal), tetapi 8 adalah angka yang lebih bulat dari 10 :)
Distribusi nilai tidak seragam, karena elemen pertama datang lebih sering daripada yang kemudian. Menurut komentar ini tidak apa-apa.
Kode awal sebenarnya dibuat menggunakan kode PHP 5.5 berikut. orig.rb
sebenarnya sama dengan kode Ruby tanpa catatan kaki ( __END__
dan data yang ditambahkan setelahnya)
generator.php
:
<?php
$d=file_get_contents('orig.rb');
$dc = gzcompress($d,9);
echo '<?php $x=file_get_contents("php://stdin");echo preg_replace_callback("/\\[(.*?)\\]/",function($m){$r=explode("/",$m[1]);return $r[array_rand($r)];},$x)';
?><?php
echo ".gzuncompress(\"";
for ($i=0;$i<strlen($dc);$i++) {
switch($dc[$i]) {
case '"':
echo "\\\"";break;
case "\n":
echo "\\n";break;
case '\\':
echo "\\\\";break;
case "\x00":case "\xaf":case "\x96":
echo sprintf("\\x%02x",ord($dc[$i]));
break;
default:
echo $dc[$i];
}
}
echo "\").\"__END__\\n\".\$x;";
(Anda dapat berpotensi menggunakan kode ini untuk zLib encompress solusi PHP untuk tantangan lain)
