So as you might or might not have known, a quine program is a program that outputs it's own source code. Since this is a lua scripting thread, I thought you guys might be interested in the lua quine code!
(deprecated)
[lua]
y = [[ print("y = [[" .. y .. "]]\ndostring(y)") ]]
dostring(y)
[/lua]
(working)
[lua]
s=[[io.write('s=[','[',s,']','];',s)]];io.write('s=[','[',s,']','];',s)
[/lua]
Tada! Try it out yourself at [url]http://www.lua.org/cgi-bin/demo[/url]
Or here's the hypothetical version of the quine code:
[lua]
s=print(s=print(s=print(s=print( --It goes on infinitely
[/lua]

To do this properly you'd do something like this.
print(file.Read(debug.getinfo(1).short_src))
Not what you posted.

Oh wait I see what you're doing. Took a couple of reads to understand what was happening.
Argh! It's deprecated from old lua syntax! Just tried it at [url]http://www.lua.org/cgi-bin/demo[/url], will upload a working one soon.

Ninja'd.
Keep in mind this doesn't apply to Gmod lua specifically, just lua by itself. Try it out at the link above

Yes! Just tried out this and it works fine!
[lua]
s=[[io.write('s=[','[',s,']','];',s)]];io.write('s=[','[',s,']','];',s)
[/lua]

It looks odd, but It's just defining a variable whilst running the write function with the same variable concatenated within a string.
Neat. Pretty useless, but still neat.
[quote=http://en.wikipedia.org/wiki/Quine_(computing)]
For amusement, programmers sometimes attempt to develop the shortest possible quine in any given programming language.

:v:
I have a shorter one! :v:

Ok, that was stupid, sorry for that. :saddowns:
Never tried to write quines, but those things look pretty fun to do when you're bored.
Nah, these guys have the shortest one, albeit in C: (International Obfuscated C Code Contest)
[quote]Worst abuse of the rules (...) An example is the world's shortest self-reproducing program. The entry was a program zero bytes in length that if run printed zero bytes to the screen (simply an empty file).[/quote]
:v:
Hahaha, now that's clever. :v:
Empty files are not quines, even if they technically print out their "source code", because there is no actual code in that case.
[editline]9th February 2011[/editline]
There's even a language that prints out "Empty files are not quines." when you try that :v:
