Script que genera un script que imprime una entrada dada

29

Escriba un fragmento de código que tome una cadena como entrada y genere un fragmento de código en el mismo idioma que, cuando se ejecute, generará la cadena de entrada inicial.

Debe poder manejar cualquier combinación de caracteres AZ, az y 0-9.

Ejemplo en Python:

import sys
print "print('" + sys.argv[1]  + "')"

Dada la entrada de testing123, volverá print('testing123').

Como se trata de código golf , la respuesta más corta en bytes ganará.

pl , 0 bytes

Código:

Pruébalo en línea!

Explicación:

Un programa vacío en pl es simplemente un programa cat, que genera exactamente lo mismo que la entrada.

En pl, todos los caracteres ASCII son esencialmente variables, pero cuando la variable no existe (todavía), pl supone que son parte de una cadena.

En la misma línea, vea Cat, que es un lenguaje interpretado como Python. La mayoría de las distribuciones de Linux modernas se entregan con un catintérprete. ;)

Esta solución también funciona para /// si considera que la entrada se agrega al código fuente del programa (ya que /// no tiene ningún mecanismo para la entrada). /// es uno de los muchos idiomas (creo) donde los caracteres alfanuméricos al comienzo del programa son simplemente de salida.

La salida requiere un intérprete que se ajuste al desbordamiento de memoria y tenga EOI = 0. TIO tiene tal intérprete.

Explicación

--[>+<++++++]Inicializa la cinta con un sencillo +.

El bucle de entrada:

,[[->.<]>+++.--.-<,]
,                     take input
 [                ,]  while input is nonzero:
  [->.<]                  output `+` input times
        >+++.             output `.` (`+` + 3)
             --.          output `,` (`.` - 2)
                -<        restore `+` and move back to input

¿No sabes Brainfuck? Te enseñaré en un comentario! Comenzamos en una cinta de 0's, con un puntero a un valor. +incrementa el valor, -disminuye el valor, >mueve el puntero a la derecha, <mueve el puntero a la izquierda, ,lee la entrada al puntero como un carácter ASCII, .emite el valor del puntero como un carácter ASCII, [inicia un bucle y ]salta al correspondiente [si el El valor del puntero no lo es 0. Soy malo para explicar, pero así de fácil es Brainfuck. Y bonito golf Conor!

  • También hay un acumulador que también contiene una cuerda o un bigint
  • todas las estaciones comienzan con su propio nombre como valor
  • Al principio, el acumulador contiene la entrada de su programa
  • Cada vez que va a una estación, el valor de la estación y el acumulador se intercambian
  • algunas estaciones son especiales y anulan este comportamiento
  • la línea que usas para llegar a una estación no importa
  • comienzas en Mornington Crescent
  • para finalizar el programa, también vas a Mornington Crescent
  • al final, se imprime el valor del acumulador

Dado que imprimir cadenas es difícil (consulte el programa "Hello, World!" De Martin Ender Mornington Crescent ), necesitaremos una plantilla simple que pueda usarse para generar cadenas genéricas. Como la duración de los programas generados no importa, me decidí por esto:

Take Northern Line to Bank
Take Northern Line to Bank
Take District Line to Paddington

Tendremos que generar cada carácter por separado y concatenarlos, ya que el enfoque de subcadena utilizado por Martin es mucho más difícil de implementar en el caso general. Paddington es la estación que realiza la concatenación de cadenas. Cuando llegas a Paddington, sucede lo siguiente:

accumulator, paddington = paddington + accumulator, accumulator

Este comportamiento se usa para inicializar Paddington en la cadena vacía que se supone que es la entrada.

Take District Line to Victoria
Take Victoria Line to Seven Sisters
Take Victoria Line to Euston
Take Victoria Line to Euston
Take Northern Line to Bank

Vaya a Seven Sisters, que establece el acumulador en 7, y guárdelo en el Banco. El Banco es la única forma de copiar valores: Hammersmith es una copia de solo lectura del valor del Banco.

Take District Line to Hammersmith
Take District Line to Cannon Street
Take District Line to Hammersmith
Take District Line to Cannon Street
Take District Line to Bank

Divide 7 entre 7 para obtener 1, un divisor de todos los valores ASCII que necesitamos admitir.

Take District Line to Hammersmith
Take District Line to Upminster

Para cada personaje, comience copiando el 1 en Upminster.

Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Upminster
Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Upminster
Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Upminster

Agregue más si es necesario.

Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Bank
Take District Line to Bank
Take Northern Line to Charing Cross
Take Northern Line to Charing Cross
Take Bakerloo Line to Paddington
Take Bakerloo Line to Paddington
Take Bakerloo Line to Charing Cross
Take Northern Line to Embankment

Termine yendo a Upminster solo una vez, para mantener el nuevo valor en el acumulador en lugar de almacenarlo nuevamente. Llévelo a Charing Cross para convertir el valor ASCII en un carácter y añádalo a la cadena. Las últimas dos líneas están allí porque he leído mal la especificación, por lo que me detendré aquí y comenzaré mi programa primero.

ies una función que inserta una cadena especificada en un índice especificado en la entrada. Qes una variable que por defecto está entre comillas ", y dado que no hay un índice dado, esto por defecto es 0. El resultado final es una comilla insertada al comienzo de la cadena, que Japt finaliza automáticamente cuando se ejecuta.

Esto funciona en cadenas que contienen cualquier cosa ", excepto , {o \, aunque, por supuesto, la cadena está garantizada por caracteres alfanuméricos, por lo que esto no importa.

MATLAB / Octave , 15 bytes

@(t)['disp ',t]

Pruébalo en línea!

Pasé por alto por completo el hecho de que el programa solo necesita manejar caracteres alfanuméricos o, lo que es más importante, no necesita manejar caracteres de espacio. Esto significa que podemos usar la sintaxis de 'comando', que usa significativamente menos bytes.

MATLAB, 27 bytes

Para completar, aquí hay una versión que puede manejar entradas arbitrarias:

@(t)['disp(',mat2str(t),41]

Define una función anónima que toma la cadena ty la convierte al programa. Curiosamente, esto no funciona en Octave, que parece tener ideas diferentes de lo que mat2strdebería hacer.

— Sanchises
fuente
No puedo probar esto, pero pienso: ¿ @(t)['disp ',mat2str(t)]debería funcionar ...?
— Stewie Griffin
@StewieGriffin Eso no funciona porque mat2stragrega comillas, que no son necesarias en la sintaxis de comandos. Tenía la sintaxis de la función combinada mat2strpara manejar espacios en la entrada, pero al releer el desafío, eso no es realmente necesario, reduciendo el bytecount casi a la mitad. ¡Gracias!
— Sanchises
Pensé que las comillas eran necesarias si había espacios en la entrada, pero podría estar equivocado. No me di cuenta de que la entrada era alfanumérica tampoco ...

Lote de 11 bytes

Estoy seguro de que hay que hacerlo más pequeño, pero esto es bastante pequeño.

set/p=echo

La caida:

set             ::Define new variable
   /p           ::Create prompt
     =          ::Define a variable in prompt
      echo      ::Prompt begins with 'echo '

En inglés:

Se le pide al usuario que ingrese una frase principal echo. Luego, el usuario puede escribir lo que sea, y el programa termina (por ejemplo, echo hello world!). Esto nos deja con un programa que, cuando se ejecuta, generará resultados hello world!.

Sí, se supone que el espacio en blanco debe estar allí

— Graviton
fuente
No sé lote (y esto es de hace mucho tiempo), pero esto se ve mal. ¿La echoporción no sería texto repetido en la consola y no salida del programa?
— Jakob
@Jakob, supuestamente no, es esencialmente funcionalmente equivalente al ejemplo de Python dado en el desafío inicial.
— Graviton
Vaya, lo que quise decir es que dudo que el programa muestre el texto que escribe el usuario. Probablemente solo se hizo eco en la consola, ¿verdad?
— Jakob
@Jakob Right, que es equivalente a imprimir. El ejemplo imprime una función de impresión mientras que la mía echos una función de eco.
— Graviton
OK, pero el ejemplo imprime todo el programa al estándar. Su programa imprime solo echo con salida estándar. De hecho, (supongo) si la entrada proviene de un archivo o una tubería, todo lo que vería es el aviso. ¿Se ha permitido ese tipo de salida?

Simplemente envuelve la cadena entre comillas usando &D, que es el equivalente de MATL a MATLAB mat2str, una función específicamente hecha para hacer algo que, cuando eval'd, dará la matriz original (o en este caso, cadena).

Cómo funciona

# //Takes the input and places it onto the string stack

{input} //The next program then consists of the input string
