PHP 5.5 -> Ruby 2.0 -> Python 2.7 -> Lua -> C # -> Java -> PdfTeX -> GolfScript 855/8 ^ 2 = 13.359375
Les idées principales étaient:
- Au lieu de créer réellement la logique pour créer le n + 1ème langage dans tous les langages de programmation, ne faites cela qu'une seule fois, et utilisez uniquement les fonctions d'écriture de base aléatoire et standard de chaque langage de programmation
- Pour raccourcir le générateur de modèles, compressez-le simplement avec zLib. Faire de ce générateur la deuxième langue
- Utilisez PHP comme première langue, car il possède un décompresseur zLib intégré
Le code initial est donc:
<?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;
Où BINARY_DATA
est la version gzcompressed du générateur de modèle (par exemple le résultat du code php, qui est la version ruby)
Le code initial complet en base64 (devrait être de 855 octets après décodage):

Remarques
Il semble que PHP soit assez indulgent avec les données binaires dans les littéraux de chaîne, à l'exception des codes hexadécimaux AF et 96. Ne demandez pas pourquoi.
J'aurais probablement pu ajouter aussi facilement du code perl et C ++ 11 (car ils prennent tous les deux en charge les littéraux de chaîne bruts), mais 8 est un nombre plus rond que 10 :)
La distribution des valeurs n'est pas uniforme, car le premier élément vient plus souvent que les suivants. Selon les commentaires, cela devrait être correct.
Le code initial a été généré en utilisant le code PHP 5.5 suivant. orig.rb
est en fait le même que le code Ruby sans le pied de page ( __END__
et les données ajoutées par la suite)
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;";
(vous pouvez potentiellement utiliser ce code pour zLib inclure des solutions PHP pour d'autres défis)
