What is a Quine

[Se7en]

for a def look here: [ http://en.wikipedia.org/wiki/Quine_(computing) ]

 

As an example (taken from): [ http://community.schemewiki.org/?quines ]

 

Cut and paste this into your command line and see what comes out.

((lambda (x) 
  (list x (list (quote quote) x))) 
 (quote 
    (lambda (x) 
      (list x (list (quote quote) x)))))

 

At the bottom of that page is a really fun challenge: produce a palindromic quine.

[ReMark]

"Devising the shortest possible quine in some given programming language is a common hackish amusement."

[Se7en]

Not quite sure i follow your train of thought. Does that post mean you don't want to participate?

Mind boggling stuff, nice find.

[ReMark]

Sounds like something that might appeal to you Lee.

[Lee Mac]

Does this count

 

(quote '(quote))

[ReMark]

Is that the shortest quine on record?

Its not quite a quine...

 

(quote '(quote))

 

Is equivalent to:

 

(quote (quote (quote)))

 

[ReMark]

Palindromes.

 

Words such as: racecar, hannah, aibohphobia.

 

Sentence such as: Was it a car or a cat I saw?

Very cool find, Se7en! Bored programmers have the most fun. :3

[Lee Mac]

Not really my own, just a variant of one supplied:

 

((lambda (p)
  (prin1
    (list p (list (quote quote) p))))
 (quote
   (lambda (p)
     (prin1 (list p (list (quote quote) p))))))

Your next attempt will be at a palindromic quine?

[Lee Mac]

I got pretty close...

 

((lambda (x) (list (reverse x) (list (quote quote) (reverse x))))
 (quote ((((x reverse) (quote quote) list) (x reverse) list) (x) lambda)))

[Se7en]

Does this count

 

(quote '(quote))

nope

 

 

 

 

 

...I hate vBulletin.

[Se7en]

I got pretty close...

 

((lambda (x) (list (reverse x) (list (quote quote) (reverse x))))
 (quote ((((x reverse) (quote quote) list) (x reverse) list) (x) lambda)))

 

Oooo! Looks a lot like my attempts too.

Can't quite get it though
