Hi,

Sorry if this is annoying, 'cause I
know we’ve done quines before, but

I just came up with this one, and was all “stoked and
stuff” (to use
80’s southern california vernacular :wink:

p eval _=“print 'p eval =’;

Quine: program that prints out its own source code.

See http://www.nyx.net/~gthompso/quine.htm for more than you ever wanted to
know about quines (site also has some great links to other programming
trivia type stuff).

They are self-reproducing computer programs; i.e., those whose output is
the same as the source code.

This usage of the term “quine” seems to have been coined by Douglas
Hofstadter (I first saw Hofsteader use that term in his book “Gödel,
Escher, and Bach”, although he may have coined it previously), in honor
of the logician Willard Van Orman Quine, who extensively studied and
wrote about the concept of self-reference.

For more information about W. V. Quine, check out his (apparently)
offical home page:

http://www.wvquine.org

It’s maintained by a family member of his.

: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.
