HTML + Javascript + jQuery + jQuery UI
La entrada debe darse en el área de texto y debe formatearse como cada comando en una línea. Los comandos no distinguen entre mayúsculas y minúsculas. Todos los comandos se implementaron completamente. Espero que lo disfrutes.

Tiene un nuevo comando:
Es el 42comando que calcula la respuesta de la vida, el universo y todo. La única peculiaridad es que lleva 7.5 millones de años terminar.
Otros spoilers:
Esta entrada tiene varias características:
- Realmente odiarás el
FAILcomando.
-
BOOM!te arruinará la "unidad de ejecución". Al menos las ventanas DONTUSEME(n)pueden sobrevivir a esto.
-
KABOOM! Es realmente peligroso para el mundo de varias maneras malas.
-
DONTUSEME(n)siempre abre infinitas ventanas vacías que no se pueden cerrar, una cada 0.8 segundos. Pero hay un interruptor oculto de matar.
-
DONTUSEME(n)sobrevive NO., FAILe incluso BOOM!. Sin embargo, no pude hacerlo sobrevivir KABOOM!. La razón es que las ventanas emergentes no funcionarán, ya que esto no es el resultado de un clic (y las ventanas emergentes creadas por otras formas están prohibidas en todos los principales navegadores), y tampoco pueden usar iframes debido a una violación de la política del mismo origen .
-
INCLUDE-xxxpuede crear cualquier instrucción, incluida DONTUSEME(n)u otra INCLUDE-yyyinstrucción.
- Si
INCLUDE-xxxgenera una INCLUDE-yyyinstrucción, el yyynombre se genera al azar. Si toma el nombre del comando generado con firebug o algo similar, puede usarlo.
- Maneja la sintaxis con formato incorrecto y la entrada incompleta o vacía.
