Hi all,
This may be a dumb question, but is it possible to write a quine in SC?
Pretty sure those of you who can answer know what a quine is, but for the rest of us, it’s “a computer program which takes no input and produces a copy of its own source code as its only output” (from Wikipedia).
I know it’s not a terribly useful use case, but interested to know.
Thanks
Perhaps slightly cheating(?) but:
value { "value" + thisFunction.asCompileString }
hjh
Curious: why do you say that’s cheating?
It does print the whole thing, right?
Thanks!! Fascinating.
The examples folder included with SC contains a document titled quines.scd, described as
“// a conversation on quines, between Julian Rohrhuber, Jens Gulden and Tim Walters.”
Could be a good place to start! 
Wow, I never even thought that would be there. Thanks!
Here, I was able to track it down for everyone:
Platform.resourceDir +/+ "Examples/other/quines.scd"
…and there’s a few online, as well:
x="x=%;x=x.format(34.asAscii++x++34.asAscii);x.postln;";x=x.format(34.asAscii++x++34.asAscii);x.postln;
Yup, that’s a cheating quine Quine_(computing)#Self-evaluation
Here’s the smallest “cheating” quine in sclang:
0
Interestingly, an empty file doesn’t work in sclang because it would output nil
Interesting – to literally take on the can-question in the title, i thought all Turing-complete languages can have quines, but now the seed of doubt has been planned in my mind…
An SCTweet Quine (by @nathan ?) :
interpret(x="/******/play{RLPF.ar(COsc.ar(b=Buffer.loadCollection(s,x.ascii.normalize(-1,1)),Osc.kr(b,1,0,65,35)),Osc.kr(b,0.1,0,300,1e3))/5}")
This original one needed some adaptation because SC was warning about
Warning: size of wavetable not a power of two (COsc)
Warning: size of wavetable not a power of two (Osc)
