PHP 5.5 -> Ruby 2.0 -> Python 2.7 -> Lua -> C # -> Java -> PdfTeX -> GolfScript 855/8 ^ 2 = 13.359375
Las ideas principales fueron:
- En lugar de crear la lógica para crear el lenguaje n + 1 en todos los lenguajes de programación, haga esto solo una vez, y solo use las funciones básicas de escritura aleatoria y estándar de cada lenguaje de programación
- Para acortar el generador de plantillas, simplemente comprímalo con zLib. Haz de este generador el segundo idioma
- Use PHP como primer lenguaje, ya que tiene descompresor zLib incorporado
Entonces el código inicial es:
<?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;
¿Dónde BINARY_DATA
está la versión gzcompressed del generador de plantillas (por ejemplo, el resultado del código php, que es la versión ruby)
El código inicial completo en base64 (debe ser 855 bytes después de la decodificación):

Notas
Parece que PHP es bastante indulgente con datos binarios en literales de cadena, a excepción de los códigos hexadecimales AF y 96. No pregunte por qué.
Probablemente podría haber agregado el código perl y C ++ 11 también fácilmente (ya que ambos admiten literales de cadena sin formato), pero 8 es un número más redondo que 10 :)
La distribución de valores no es uniforme, ya que el primer elemento se presenta con mayor frecuencia que los posteriores. Según los comentarios, esto debería estar bien.
El código inicial se generó realmente usando el siguiente código PHP 5.5. orig.rb
en realidad es lo mismo que el código Ruby sin el pie de página ( __END__
y los datos adjuntos después)
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;";
(potencialmente puede usar este código para zLib abarcar soluciones PHP para otros desafíos)
