Let's write quines ... - 2005/03/19 02:20
:quine: /kwi:n/ n. [from the name of the logician Willard
van Orman Quine, via Douglas Hofstadter] A program that generates a
copy of its own source text as its complete output. Devising the
shortest possible quine in some given programming language is a
common hackish amusement. Here is one classic quine:
((lambda (x)
(list x (list (quote quote) x)))
(quote
(lambda (x)
(list x (list (quote quote) x)))))
This one works in LISP or Scheme. It's relatively easy to write
quines in other languages such as Postscript which readily handle
programs as data; much harder (and thus more challenging!) in
languages like C which do not. Here is a classic C quine for ASCII
machines:
char*f="char*f=%c%s%c;main()
{printf(f,34,f,34,10);}%c";
main(){printf(f,34,f,34,10);}
For excruciatingly exact quinishness, remove the interior line
breaks. Some infamous {Obfuscated C Contest} entries have been
quines that reproduced in exotic ways.
