許可された場合、これを11バイトに短縮できます。:(
説明:
'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".

説明:
& 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)
私もそうかもしれないので、スタック内で発生するステップの図を次に示します(各スタックはで表されます[]
)。
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).
実際にこれがどのように機能するかはわかりません。微妙な変化はこれを壊します。たとえば、&
他のさまざまな場所にを配置しても同様に機能するはずですが、配置する場所に応じてClassCastException
s、IOException
s、およびArrayOutOfBoundsException
sが発生します。バグ修正が必要になるかもしれません。
