Q: Golf you a quine for great good!

Rafe KettlerUsing your language of choice, golf a quine. A quine is a non-empty computer program which takes no input and produces a copy of its own source code as its only output. No cheating -- that means that you can't just read the source file and print it. Also, in many languages, an empty file is...

Cryptomnesia
Cryptomnesia occurs when a forgotten memory returns without it being recognized as such by the subject, who believes it is something new and original. It is a memory bias whereby a person may falsely recall generating a thought, an idea, a song, or a joke, not deliberately engaging in plagiarism but rather experiencing a memory as if it were a new inspiration. == Early use == The first documented instance of cryptomnesia occurred in 1874 with the medium Stainton Moses.

ais523
ais523
@Challenger5 depending on how it was encoded, you can often decode it to various levels by looking for a parenthesized group that follows a closing square bracket (i.e. ](…)) and just eval'ing that, although doing so isn't necessarily safe
JSF*ck is capable of using multiple levels of eval, in which case you can't decode it in general without executing arbitrary code
(you could call that obfuscated JSF*ck, I guess? not that the difference between obfuscated and nonobfuscated is readily visible to a human)

@Dennis just to clarify: it's legal for me to add builtins for sandboxed problems to a language I'm writing, if I don't subsequently use that language to answer the question? the current wording of the loophole implies it's the language design that breaks the rules, not the answer

Of course not. We get math challenges all the time.
 
Challenger5

If I know said user is about to post a challenge, and I suspect it's about combinatorics, so I add a bunch of combinatorics builtins to my language, is that "prior knowledge?"

Whenever you have to suppose, it's not prior knowledge.

something that'll probably never happen, but I'd kind-of like to see, would be to word the "no designing languages to solve a specific challenge" rule by requiring the language to be competitive on a wide range of challenges

Phoenix

3:57 AM
Also, java 9 has JShell, so you can make complete programs in it without boilerplate
It's just currying
 
ais523
ais523
right, it's just that currying cares a lot about closures to work correctly, and Java isn't very good at closures
 
Challenger5
Challenger5
The problem I have with Java is that they give built-in types all this magic behavior.
The designers are favoring natives and discriminating against ones of a different `class` .
Also, how come bowling was picked rather than basically any other sport where you try to get as high a score as possible?
 
ais523
ais523
hmm, if we have code golf, code bowling, and code shuffleboard
we should have code darts
it's like code shuffleboard but you have to end on a double

How about a king-of-the-hill challenge where the users designed an A.I. for chutes and ladders?
That would be fun
 
ais523
ais523
I thought you only had one legal move in any given situation
meaning that all the programs would be effectively identical
or is that game a different one from the one I'm thinking of? (In the UK there's a game called "snakes and ladders", I assumed "chutes and ladders" was a US name for the same thing)
 
Destructible Lemon
Destructible Lemon
4:02 AM
no
how about a game
where different information about a roll is revealed to different bots, and you can call a player out for cheating
but other than that it is chutes and ladders
 
ais523
ais523
hmm, Cheat! itself might make for an interesting challenge
despite the fact that the rules don't appear to be standardised
every version I've seen is "the players take turns to play sets of cards face down, there's a condition which limits which sets can safely be played, you can challenge someone and if their set is unsafe, they have to pick up all the face-down cards, otherwise you do, first to empty their hand wins"
however, what the safety condition actually is seems to vary a lot from community to community, and I'm not sure if any of the ones I've seen are really ideal
 
Challenger5
Challenger5
That reminds me of the card game B.S. Is there already a KOTH for that?
@ais523 And yes, that was the point.

that said, Jelly happens to have a special case specifically for solving this sort of reuse

which is what caused all the misunderstandings ensued

so I think it'd be hard to beat in this specific case (because it's fairly rare that it's useful and so a golflang which specialised in reusing data would probably use that syntax for something more common)

Honestly, I don't know how to do it in Brain-flak

@ais523 One idea that has been going around in my mind for a long time is modifying how unchainable constants work. Right now, they just replace the return value (and print the old one), which is useful on occasions, but not frequently enough to keep it.
Unchainable constants could push the previous return value on a stack instead (with infinite repetitions of the argument of a monadic chain at the bottom), so subsequent hooks and forks would pop that stack instead of operating directly on the argument. That might help to eliminate a bunch of $.

@LeakyNun Perl 6: {$^a+$^b*(1|-1)}
that was surprisingly fun to golf; it's a fairly weird algorithm

@ais523 does Perl have a golfier input system?

@WheatWizard Hmm, I think a step by step debugger (or at least printing stacks out after every operation) would be kinda useful

@LeakyNun Perl 6, probably not
a variable is $a, the ^ makes it implicitly input

@ASCII-only Yeah I would like to make one some time

And besides, the repl.it interpreter does numeric i/o.

@Challenger5 you can save one byte by interchanging the second and the third cell
(the program starts at the first cell)

Now that that is resolved back to the depths until someone mentions Brain-Flak again

I'm a bit leery of whatevers
you don't really expect a programming language to have a command for "do something"
like, you expect them to be more specific
but they invent implicit function parameters in this sort of context (and in fact, make the expression they're in into a function)
 
Challenger5

Okay, so apparently the repl.it BF interpreter uses numeric input, bigint cells, but character output?
I don't want to think about the repl.it BF interpreter ever again after an incident a few months back that I don't want to think about

@LeakyNun C, 50 bytes. Returns a pointer to the array. Try it online!

But it doesn't have numeric i/o, just sane i/o. Which in this case is not good.

@Challenger5 well if you want it enough you can just submit a brainfuck interpreter to TIO with whatever flags you need e.g. numeric i/o

I really like the syntactic overloading in CJam. It's very cleverly done. For example:
`.` for float literals / vectorize
`:` for set var / map / reduce
`e` for extra / scientific notation
`m` for math / minus

Also, has anybody ever used j (memoized recursion) in CJam? It seems useful, but I don't think I've seen it around.

@WheatWizard Here's a hard one to solve in Brain-Flak: codegolf.stackexchange.com/q/37554/61384

yeah, that is very hard
 
ais523

it wouldn't surprise me if it had no efficient solution
(obviously it's possible due to Turing-completeness, but the tricks you have to use to solve that sort of program in a language that limited tend to really slow it down a lot)

I tried to do it in Underload (well actually in Betaload (github.com/ScratchMan544/betaload-lang)) and gave up really quickly
