Vitsy, 10 27 octets
'rddd++&"rdd8++a[v}v1-D);].
Si cela :
était autorisé, je pourrais le raccourcir à 11 octets. :(
Explication:
'rddd++&"rdd8++a[v}v1-D);].
' Capture all instructions as a string until encountering
' again, looping if necessary.
r Reverse the current stack (output is top-down).
ddd++ Push char literal ' to the stack.
& Push a new stack to the stack stack.
" Same as ', but " specific.
r Reverse the current stack.
dd8++ Push char literal " to the stack.
a Push 10 to the stack.
[ ] Loop forever.
v Capture the top value as a variable.
} Take the bottom item of the stack and put it on the top.
v Dump the variable to the stack.
1- Subtract 1.
D Duplicate the top item.
); Pop n; if n is 0, exit the loop.
a[v v1-D);] This is a makeshift for loop with 10 iterations.
. Pop the top stack as n, and the second stack as o.
Write a file called "n" with the contents of "o".
Les deux piles seront identiques à la fin. Sur certaines versions de Java, cela peut générer un en FileNotFoundException
raison des différentes implémentations de la FileInputStream
classe.

&'rddd++}.
Explication:
& Push a new stack to the stack stack.
'rddd++ Modified standard quine.
} Move the ' to the right place.
. Pop the top stack as n, and the second stack as o. Write a file called
"n" with the contents of "o". (Quine name, no content)
Parce que je pourrais aussi bien, voici un diagramme des étapes qui se produisent dans les piles (chaque pile est représentée par []
):
Initial state: [[]]
& [[], []]
Push a new stack to the stack stack.
' [[], ["r", "d", "d", "d", "+", "+", "}", ".", "&"]]
This stack state occurs because ' will loop around the line
until finding the next '.
r [[], ["&", ".", "}", "+", "+", "d", "d", "d", "r"]]
Reverses the top (last) stack.
ddd [[], ["&", ".", "}", "+", "+", "d", "d", "d", "r", 13, 13, 13]
Push thirteen thrice.
++ [[], ["&", ".", "}", "+", "+", "d", "d", "d", "r", "'"]
Because char ' is 39 = 13 + 13 + 13.
} [[], [".", "}", "+", "+", "d", "d", "d", "r", "'", "&"]]
Takes the bottom item, then puts it on the top.
. []
Writes a file with content from the second-to-top stack and the
name as the concatenation of all elements in the top stack,
with top member priority (backwards from my representation).
Je ne sais pas vraiment comment cela fonctionne correctement; des changements infimes provoquent une rupture. Par exemple, placer le &
dans divers autres emplacements devrait tout aussi bien fonctionner, mais cela entraîne ClassCastException
s, IOException
s et ArrayOutOfBoundsException
s selon l'endroit où vous le placez. Je devrais peut-être faire quelques corrections de bugs.
