Como parte de su respuesta a Cometer un error Quine! @Falko propuso el siguiente algoritmo:

¿Cómo crear su propia solución en 2 minutos?

1. Abra un nuevo archivo en un IDE de su elección.
2. Golpea tu cabeza con el teclado frente a ti.
3. Compilar.
4. Reemplace el código con el mensaje de error del compilador.
5. Repita los pasos 3 y 4 hasta que el código converja.

¡Apuesto a que tal procedimiento termina bastante rápido en la mayoría de los casos!

Tarea

Tu tarea es demostrar que está equivocado.

Escriba un programa completo que satisfaga lo siguiente:

1. Cuando se compila o interpreta, produce un mensaje de error que, cuando se compila o interpreta a su vez, también genera un mensaje de error.

2. Si repite el paso 1 una y otra vez, eventualmente encontrará un punto fijo, es decir, un error quine.

Reglas adicionales

• El mensaje de error final debe tener una longitud positiva. Sin embargo, los mensajes de error anteriores y el código fuente original pueden estar vacíos.

• La longitud del código fuente original no puede exceder 1024 bytes.

• Ni el código original ni el código generado en ninguno de los pasos pueden producir resultados sin errores.

  La salida debe ser claramente identificable como un mensaje de error, que debe ser generado por el compilador / intérprete debido a un error de sintaxis, error de tiempo de ejecución, referencia indefinida, etc.

• Es posible que su programa no reciba ninguna entrada o requiera ningún indicador para producir el bucle.

• Su programa puede depender de una implementación específica de su idioma o versión del mismo.

Tanteo

Su puntaje es el número finito de pasos que requiere su código fuente antes de producir un error quine. La presentación con la puntuación más alta gana.

La longitud del código fuente original se utilizará como disyuntor. Más corto es mejor.

Ejemplo

En pollo , el programa

genera el siguiente mensaje de error:

TypeError: Cannot read property 'NaN' of undefined

Si este mensaje de error es, a su vez, interpretado, produce el mensaje de error

Error on line 1: expected 'chicken'

que, si se interpreta a su vez, se produce a sí mismo.

Por lo tanto, el puntaje del programa Chicken vacío es 2.

Contraejemplo

El código PHP

ab<?=c

genera el mensaje de error

PHP Parse error:  syntax error, unexpected '?' in Command line code on line 1

que se produce cuando se interpreta.

Sin embargo, el segundo código fuente imprime el mensaje en STDOUT, lo que invalida esta secuencia.

Bash, 9223372036854775810

Inspirado por la respuesta de Doorknob.

a='"2>/dev/null;if(((i=$((i-1)))>0));then $(declare -p a);$a;else 1;fi #"'
i=2**63
eval $a

Debe ejecutarse con bash < file.sh, o usar el mismo nombre de archivo para cada programa, para deshacerse de los diferentes nombres de archivo en los mensajes de error.

Los primeros errores son (con LANG=C):

bash: line 3: 2>/dev/null;if(((i=9223372036854775807)>0));then declare -- a="\"2>/dev/null;if(((i=\$((i-1)))>0));then \$(declare -p a);\$a;else 1;fi #\"";"2>/dev/null;if(((i=$((i-1)))>0));then $(declare -p a);$a;else 1;fi #";else 1;fi #: No such file or directory

bash: line 1: 2>/dev/null;if(((i=9223372036854775806)>0));then declare -- a="\"2>/dev/null;if(((i=\$((i-1)))>0));then \$(declare -p a);\$a;else 1;fi #\"";"2>/dev/null;if(((i=$((i-1)))>0));then $(declare -p a);$a;else 1;fi #";else 1;fi #: No such file or directory

bash: line 1: 2>/dev/null;if(((i=9223372036854775805)>0));then declare -- a="\"2>/dev/null;if(((i=\$((i-1)))>0));then \$(declare -p a);\$a;else 1;fi #\"";"2>/dev/null;if(((i=$((i-1)))>0));then $(declare -p a);$a;else 1;fi #";else 1;fi #: No such file or directory

Y finalmente:

bash: line 1: 2>/dev/null;if(((i=0)>0));then declare -- a="\"2>/dev/null;if(((i=\$((i-1)))>0));then \$(declare -p a);\$a;else 1;fi #\"";"2>/dev/null;if(((i=$((i-1)))>0));then $(declare -p a);$a;else 1;fi #";else 1;fi #: No such file or directory

bash: line 1: 1: command not found

bash: line 1: bash:: command not found

lo cual es un error quine.

Pip 0.15.05.29 , más de 10 ^100,000

Técnicamente no es válido porque requiere la -wbandera para la salida de advertencia. Dicho esto, Pip por diseño no muestra ningún error de tiempo de ejecución a menos que realmente bloquee el programa (recursión infinita, por ejemplo); Los problemas con este código son cosas de las que otros idiomas definitivamente se quejarían.

i:5**6**7d:"i:1d: Ssi?dRo--iRsRPda"Ssi?dRo--iRsRPda

El número exacto de pasos depende solo del valor asignado i, por lo que podría ser arbitrariamente grande (hasta que el intérprete de Python se quede sin memoria). Además, tomaría más tiempo que la edad del universo completar la secuencia anterior. (La pregunta se especifica "lento"!)

Explicación:

Me tomó un tiempo revisar el intérprete antes de encontrar un error que me permitiera poner un código arbitrario en el mensaje de advertencia. Después de eso, esencialmente estaba modificando las técnicas estándar de quine. El ejemplo aquí usa un ivalor de 5para propósitos de explicación.

i:5d:"i:1d: Ssi?dRo--iRsRPda"Ssi?dRo--iRsRPda

Después de la configuración i, almacene una cadena dy luego intente ejecutar la Sinstrucción wap. Swap espera dos variables (más exactamente, valores). sestá bien, pero la segunda expresión es i?dRo--iRsRPda. Si ies verdadero (distinto de cero, para nuestros propósitos), el ternario evalúa a dRo--iRsRPd, que utilizad desde antes para formar una quina cercana, solo con idecremento. Esta expresión no es un valor, por lo que Pip se queja:

Attempting to swap non-lvalue i:4d:"i:1d: Ssi?dRo--iRsRPda"Ssi?dRo--iRsRPda

... que luego comienza todo de nuevo. (Attempting to swap non-lvalue es un montón de no-ops: Atcalcula el valor ASCII de t = 10, n-lresta nueva línea menos cada valor de una lista vacía, y todas las letras minúsculas son solo variables).

El proceso continúa de manera similar hasta:

Attempting to swap non-lvalue i:0d:"i:1d: Ssi?dRo--iRsRPda"Ssi?dRo--iRsRPda

Cuando esto se ejecuta, iahora es falso. La expresión ternaria se evalúa en la rama elsea es un valor l. Por lo tanto, el intercambio ya no se queja. En cambio, obtenemos:

Referencing uninitialized variable a

Y al ejecutar esto, por fin, tenemos un error de sintaxis real:

R is not a unary operator
Fatal error while parsing, execution aborted.

... en ese punto, ya que el "programa" comienza con R , Pip continuará quejándose de que Rno es un operador unario para siempre.

La mejor solución que no usa -wes de longitud 3:

$~

While scanning, ignored unrecognized character: '~'
Missing operator for $ meta-operator? Got None instead
Fatal error while parsing, execution aborted.

Missing operator for $ meta-operator? Got m instead
Fatal error while parsing, execution aborted.

M is not a unary operator
Fatal error while parsing, execution aborted.

Julia, 3

Una simple para hacer rodar la pelota ...

Programa inicial:

inquisition

Error 1:

inquisition not defined

Puede que no esté definido, pero si es español , también es inesperado. Nadie espera la inquisición española.

Error 2:

syntax: extra token "not" after end of expression

Error 3:

syntax: extra token "token" after end of expression

El tercer mensaje de error, cuando se envía como un programa, produce el mismo error, de ahí la puntuación de 3.

¡Trabajo en progreso! Seguramente puedo hacerlo mejor que 3.
