## Quine (#207)

Ahn nyeong Rubyists,

This week's quiz is to create a quine[1], that is: a program which
receives no input and produces a copy of its own source code as its
only output.

Have Fun!

 

[Bill Kelly]

This week's quiz is to create a quine[1], that is: a program which
receives no input and produces a copy of its own source code as its
only output.

I have mine down to down to one line (29 characters), though I
suspect everyone will agree I'm cheating.

I have 30 characters, w/out cheating. It does output a warning
on 1.8.6, but not 1.8.7 or 1.9.1. (And since the warning is on
stderr, it doesn't affect the quine output really, I guess.)


Regards,

Bill

I have 19 characters with cheating. 14 if it only needs to run on unixoid-
systems.

Well, 15 if it needs to work correctly ;-)

I've got one that is more than 40 characters, but it's _readable_!

Did you mean: ((I've got (one)) (that is more than ((40) characters)), ((but) (it's _readable_!)) ?

Well I could have done something like that, yes, but I restrained myself this time


Too bad we've got only oneliners, a subsidiary questions would have
been to produce a reversed quine, a quine that outputs the source
lines in the reverse order. (In C it's funny).

There is only one way to respond to that mess of redundant )

I've got one that's 197 characters, but it:

+ is readable and formatted nicely
+ uses gems
+ uses a class
+ shows the inheritence of said class
+ has more than one instance of "end"
+ took me less than 5 minutes to write

;-)

Now to try for brevity....

Ok, I'm at 17 if I ***cheat*** & assume *NIX.
and 28 if I don't cheat.

Still kinda fun, though.... the one at 28 bytes is not anything I'd use
in real life, however. Definitely not maintainable.

Ha, I just made one with 0 chars. Top that!

Hehe.

We did quines on ruby-talk back in 2002, and that is
indeed where we ended up.

(Although, personally, I tend to find nonzero length
quines more interesting) ;D

0 bytes, what else?

 

[Rick DeNatale]

0 bytes, what else?

And how do you execute it and prove it works, mon ami? <G>

Ok, the shortest solution did not have much success, what about a long
one then
