Hablando en esotérico

Hoy traigo un script que programa en lenguajes esotéricos, concretamente en Brainfuck, Ook!, Whitespace y Zombie.

Lo único que hace es escribir un programa que muestre por pantalla lo que el usuario pida, su uso es:

=============================================================================== ./esoprint.py [-h] [-l ] [-o ] [ [ | -n [...] ] | -n] -h (--help): muestra esta "ayuda" -l (--language): Selecciona el lenguaje -o (--output) : Selecciona el archivo de salida (a stdout por defecto) El resto se toma como información, el -n (--newline) es considerado un salto de línea ===============================================================================

El script se puede descargar [aquí] o al final coloreado

Dejando a parte de Brainfuck y Ook!, de_los_que_se_habló_antes, Whitespace es un lenguaje compuesto únicamente por espacios, tabuladores y saltos de línea, con un conjunto de instrucciones bastante completo [Whitespace_Tutorial] . Zombie está por estar, ni siquiera encontré un intérprete así que no puedo asegurar que funcione, simplemente parecía fácil de programar :).

Y eso es todo.

Tengo que dejar la manía de poner los comentarios en inglés :S ...
