HTML + Javascript + jQuery + jQuery UI
Input harus diberikan di area teks dan harus diformat sebagai setiap perintah dalam satu baris. Perintah tidak peka huruf besar kecil. Semua perintah diimplementasikan sepenuhnya. Saya harap Anda menikmati.
Anda dapat mencobanya di http://jsfiddle.net/bCBfk/

Ini memiliki satu perintah baru:
Ini adalah 42perintah yang menghitung jawaban dari kehidupan, alam semesta dan segalanya. Satu-satunya kekhasan adalah bahwa dibutuhkan 7,5 juta tahun untuk menyelesaikannya.
Spoiler lainnya:
Entri ini memiliki beberapa fitur:
- Anda benar-benar akan membenci
FAILperintah itu.
-
BOOM!akan mengacaukan Anda "unit eksekusi". Setidaknya windows dari DONTUSEME(n)mampu bertahan ini.
-
KABOOM! benar-benar berbahaya bagi dunia dalam beberapa cara buruk.
-
DONTUSEME(n)selalu membuka jendela kosong tak terbatas yang tak bisa ditutup, masing-masing 0,8 detik. Tapi ada saklar bunuh yang tersembunyi.
-
DONTUSEME(n)bertahan NO., FAILdan bahkan BOOM!. Tapi aku tidak bisa bertahan hidup KABOOM!. Alasannya adalah bahwa jendela sembulan tidak akan berfungsi karena ini bukan hasil dari klik (dan sembulan yang dibuat dengan cara lain telah lama dilarang di semua peramban utama), dan tidak dapat menggunakan iframe juga karena melanggar kebijakan yang sama-asal mula .
-
INCLUDE-xxxdapat membuat instruksi apa saja, termasuk DONTUSEME(n)atau INCLUDE-yyyinstruksi lain .
- Jika
INCLUDE-xxxtidak menghasilkan INCLUDE-yyyinstruksi, yyynama dihasilkan secara acak. Jika Anda mengambil nama perintah yang dihasilkan dengan pembakar atau yang serupa, Anda dapat menggunakannya.
- Ini menangani sintaksis cacat dan input tidak lengkap atau kosong.
