@Zacharý if it were ltr, you would be able to use -⍨/
@Zacharý apl is unparsable
 
1 2 3 a 4 5 6 could be multiple different things
 
@Dennis O_o
 
Operators ...
 
I wonder how long Charcoal would take to do that (it would probably time out. plus I don't think there's a way to easily instantiate a Rational yet.)
 
@ASCII-only reminds me of the brain-flak quine
 
12:10 AM
Is -⍨` in LTR equivalent to -` in RTL? That doesn't seem right...
 
ngn
@Zacharý up to a sign
 
Ah, I see...
 
ngn
for -/ at least
 
Finally, all tests pass again >_> (read: time to prepare for tests for fail for another few days)
 
ngn
@Zacharý was that a response to my comment that apl is unparsable?
 
12:17 AM
The worst part about right-associative scan is that it requires a separate computation for each prefix. Unless the interpreter can figure out that the function is associative
 
ngn
@H.PWiz yeah, it's O(n^2) for user-defined functions
 
What's the most bountied answer on SE?
There's a SciFi.SE answer that's at +3850 from bounties (and that also happens to be the sole post of the user on the site), and I haven't seen anything more than that
 
@ASCII-only C takes 0.035 seconds with GMP.
 
@Dennis As a rational?
 
Yes.
Takes slightly longer on TIO, because it counts compilation time. tio.run/##RU7LCoMwEDwnX7FYChG11F61/YXSe0Ek0XQhiY/EU/…
 
12:32 AM
Haskell has it at 1 second
 
Nice! Python 3 + gmpy2 gets it in 0.060 seconds. tio.run/…
 
Surprising
gmpy2 must be pretty heavy C
 
It's supposed to be a very thin wrapper around GMP and MPFR.
 
Looks like GHC uses gmp. The slowness probably comes down to rationals being defined inside of Haskell
 
Heck, import sympy takes 100 times longer that computing the sum with gmpy2.
 
12:37 AM
whats your Haskell?
(code)
 
@EsolangingFruit probably the branch prediction fail answer
 
@EsolangingFruit If you include all 6 of them as one answer, then it's QFT
 
@H.PWiz Try -O3.
 
Right, I was only providing the code
 
12:39 AM
Huh that's only at 1550
 
@Dennis O_o I should probably switch Charcoal to gmpy2
 
What is it using now?
 
Python >_>
 
@Zacharý tio.run/##S85JTcz7/z83P6U0J1UhNzEzjysztyC/… - in Clean, ofc Haskell can do it too, so can others.
 
Probably the built in fractions module then
 
12:42 AM
> x.denomintor
how has this not been fixed yet D:
How fast is mpz compared to Python's int? nvm they say in the wiki page
@quartata Charcoal? No, it's using pure Python int arithmetic >_>
 
you mean you wrote the rational code yourself?
 
Yes. And it's not very fast, nor does it contain anything resembling good code
 
Rational code is easy to do.
So your rational code isn't RATIONAL?

@Zacharý not easy to do it fast
 
12:48 AM
Does anyone know if gmpy2 (or gmp)'s precision applies to integers, rationals and complex too?
 
@Zacharý Here we go: tio.run/…
 
there's a couple extensions for complex numbers
at least in C world
 
hang on never mind >_> I can just (somehow) cast to real
 
@HyperNeutrino why
 
12:52 AM
@Οurous because I can >:-D
 
ngn
@HyperNeutrino complex complex numbers are just complex numbers: (a+ib) + i(c+id) = (a-d) + i(b+c)
 
@ngn nope. a complex number in C++'s complex library is defined as a pair of numbers with the operations overloaded
complex complex numbers should be complex numbers but they aren't in this implementation/meaning of the term
 
@HyperNeutrino Yeah, instead they're complicated numbers.
 
wtf c++
 
12:58 AM
basically (a, b) + (c, d) := (a + c, b + d)
 
so complex numbers are just twoples in c++
 
(a, b) * (c, d) = (ac - bd, ad + bc)
(a, b) / (c, d) = (a, b) * (c, -d) / (c^2 + d^2)
-(a, b) = (-a, -b)
etc, you get the point
it doesn't matter what a, b, c, d are, just that they support those operations
because C++ doesn't support restricted template arguments (IIRC) so you can put anything in there, it's just that it won't compile if it doesn't support the required methods/fields/operations
 
@DJMcMayhem I don't.
@quartata That's at +1550. The answer I mentioned is more than double that.
 
@HyperNeutrino I have a feeling we've had this conversation before...
 
@Zacharý I have with you before :D
 
1:17 AM
@EsolangingFruit :/ There's no easy way to find total bounty for a question
 
@HyperNeutrino you use template traits for that
you're right though in that it's all dependent on SFINAE
 
I'm not sure why a 2D language needs a builtin to read environment variables but now I have one.
 
My monitor is borked
It's like everything has a drop shadow to the right.
Does anyone know this problem?
 
@feersum Only if your monitor is a website and it has questionable CSS.
 
nvm pushing in the cable fixed it.
 
1:50 AM
@EsolangingFruit You're right
 
@ASCII-only Fixed
 
2:11 AM
Is there any disadvantage for using gmpy2 for all calculations?
 
It's slower for everything that could be done with native types.
To the processor, not Python. 64-bit ints will be faster than gmpy2.mpz.
 
Anonymous
gmpy2 will be slower than Python regardless - the extra cost of running a non-native library will make it slower than just using Python's longs
 
Anonymous
The Python runtime -> gmpy2 -> gmpy transitions alone will be quite costly
 
2:32 AM
@Mego Wait, but gmpy2 said it's faster for calculations > 20-50 digits :/
@Dennis But would it be faster than switching between Python and gmpy2 depending on the calculation?
 
It depends on what you're doing. If you're going to sum a huge amount of different integers, the cost of typecasting will be higher than the save in computation time. If you have a small amount of integers you're performing expensive calculations on, gmpy2 will be much faster.
 
Anonymous
@ASCII-only True... It's reasonable that, for some length, the extra cost of running native gmp code from Python is less than the cost of performing the same calculations with Python's longs
 
@Dennis What if you directly translate from source code (string) to e.g. mpz?
Or do you mean a huge amount of numbers with different GMP types?
 
Things like sum(map(mpz, range(10 ** 8))) must absolutely be avoided.
Even sum(range(10 ** 8), mpz(0)) is way too slow.
 
2:47 AM
@Dennis oh, ranges :/
 
But if you don't typecast all the time, the performance difference is less. tio.run/##bY49DsIwDIX3nMJbEtEhhQ3oFXoIpJRGwnEUGaH28sFtUwQSHvzz/…
Actually, that's not quite fair because of the import.
Better. tio.run/…
 
Hmm so basically avoid unnecessary instantiation
 
ok so, what if i wanted to interact with a list, but it's in a nested list, and i want to use an integer to represent how nested it is?
 
@DestructibleLemon what exactly do you mean by that, example?
 
so, i'm parsing bf
if i come across a [, i start a new list
 
2:55 AM
@DestructibleLemon why can't you just use an integer
 
if there have been 5 [ so far, and no ], that means that program[-1][-1][-1][-1][-1] is a list that is being edited with the commands inside the loop
obviously that looks ugly as frick
and also not arbitrary
 
every time you recurse just add call_stack[-1][-1] to the call stack and when you unrecurse then del call_stack[-1]
 
@DestructibleLemon well yeah but you're never actually going to type program[-1][-1][-1][-1][-1]
 
i guess i could use repeated assignment of like, for i in range(thingy): current_program = current_program[-1] but that looks rather inelegant somehow
@ASCII-only exactly, which is why i need to know how to use an integer for this task
 
@DestructibleLemon why?
 
2:58 AM
g = lambda a, r: g(a[-1], r - 1) if r else a
send code please? this is not a good way of doing this
 
just use a list of indices as IP
 
@ASCII-only because i can't type [-1][-1] and i feel like there should be a not hacky way of doing this
 
send code @destructible I'm pretty sure there's a way better way of doing what you're trying to do
 
i've written like nothing
tape = [0]
program_string = input("input program")
parsing = True
program = []
while parsing:
which gives a syntax error because i haven't written any of the actual parser
 
you don't really need to parse BF, you can just interpret it. why do you need to parse it?
 
3:01 AM
parse it into an easier to interpret state?
 
ok makes sense I guess
so how should the parse tree for ,+++[>++<-]>. look
 
@DestructibleLemon well of course you can't type [-1][-1], you don't know there's a list there
,+++
  >++<-
>.
@HyperNeutrino
 
ok makes sense
still don't see why that's necessary because it will recursion error way sooner than regular interpretation will, but okay
 
otherwise, loops are a huge PITA
@HyperNeutrino no?
 
yes...?
 
3:04 AM
wait a second, i wrote a bf interpreter before, i can just look at that one and copy it with minor modifications
 
@HyperNeutrino you're just pre-extracting the loops so you won't spend O(length(code)) time looking for the matching bracket?
@DestructibleLemon ...
 
copy paste
the requirements i have for the new interpreter are a bit different though
 
@ASCII-only yes but it will still recursion-error earlier, potentially. actually if you implement it correctly it won't so never mind ignore me ಠ_ಠ
also you won't have 1000 nested loops
 
so it makes sense i need a new one

more confusing than I expected, I guess :P
 
i know how it could be less confusing
wait actually it's not very elegant
alright so... i think i saw some sort of list indexing/slicing notation that included ,
was that a dream or was that real

@DestructibleLemon numpy uses "extended" slicing. It's just regular slicing with __getitem__, but it works with tuple arguments
 
I mean it probably loads very quickly if routed through TOR because of the simplicity in its design :P

alright, now i'm going to do a good old copy paste of the program i made a while ago and then modify to be arbitrary cell size
 
3:19 AM
why are we getting flooded with off-topic questions
 
also should i include randomness in it? i think i won't because it's likely that there are similar bf interpreters, but not ones that will likely have randomness.

@HyperNeutrino Assuming no copyright infringement issues, there is no firm policy other than "use your best judgment". We don't want to compromise the integrity of external contests, but we also don't want to turn away valid challenges.

@WheatWizard In addition to what I said in my comment, my script has Stack Overflow hardcoded :P
 
3:28 AM
Fair enough
 
@ASCII-only why do you only have limited cells
 
@DestructibleLemon because it's easier :P
It isn't hard to change it to infinite though
 
yeah i seem to have been able to just delete a %256 in my program, so it now complies, except i need to get rid of randomness
ps. mine is more efficient
newlines are read as 0, because i didn't realise that that might be better than considering it end of line
it's called interbf because it has interactive i/o
 
mine stores contiguous runs of the commands <>-+ as a list of effects
like +1 to cell 2 to the left, and -5 cell 7 to the right
hence it is more efficient
take that
 
3:34 AM
@HyperNeutrino oh yeah that's much better
 
i should probably add the ability to deal with EOF
how is EOF communicated on tio?
 
@DestructibleLemon well those are basically useless compared to the optimizations bfo makes
 
what does bfo do?
 
optimize loops, collapse runs of commands (into one) (this includes opposite commands, e.g. <> is removed), idk what else
Not sure, but it might recognize simple polynomials or something
 
@ASCII-only mine does all of those except the first?
actually was that only 2 things listed?

@Mego so how would that work for a python interpreter?
 
@DestructibleLemon ...the same way you detect EOF in Python normally?
 
i haven't done that before
 
3:39 AM
@DestructibleLemon EOF is met if std.stdin.read(1) returns ""
You can just do input_string = input_source.read() to read the whole thing
 
i'm using input() though
 
well that will error if you're at EOF

Probably for compatibility: by matching \r?\n, you can match both styles of line endings very easily. The standard says use \r\n, but applications should be able to handle \n.
 
3:47 AM
there should really be a regex operator to do a or b or both
 
Anonymous
\r\n doesn't affect \n systems at all, but \n makes stuff unreadable on \r\n systems
 
so you don't have to do a?b|a
 
that said, mine doesn't optimise double brackets though, but at the same time that's not super necessary
 
@HyperNeutrino or both implies ba is also allowed

anyone else get that or am i just weird
 
@HyperNeutrino how can you finish exactly on time without it being last minute

@Adám still don't think it's a good advice to be honest...
Creating and solving challenges require very different skills.

@StewieGriffin But trying to solve challenges forces into the mindset of the future reader. Doesn't matter if the potential challenge author is very good at solving problems.
 
But the user might not even enjoy solving problems.
As I said, I do understand your reasoning, but I don't like discouraging users from creating challenges.
My first post was a challenge by the way. I would not have liked if someone asked me to not post challenges until I've solved some myself.
 
Also IIRC Helka doesn't really solve problems?
 
@StewieGriffin Oh well, at least it is phrased as a personal recommendation.
 
@Adám :)
 
If you only have a hammer, you tend to see every problem as a dupe.

@StewieGriffin While some users may be able to write good challenges right off the bat, most new users we get do not. Answering challenges first is a good way to get experience with the site before trying to write a challenge. However, it's ultimately a recommendation, and not a mandate.

@Adám I don't have a hammer, but most Stack Overflow problems are indeed a dupe.

I've been trying to ''optimize'' my use of the jump drive in Stellaris to minimize the days taken for travel, but keep it above 120 days so the debuff wears off. I just realized that could be a awesome puzzle.

@ngn just pseudocode would be a great start
 
tfw your work building is running on half power
 
I was looking at Wunderground for the weather and I decided to make a table of the weather icons they use. jsfiddle.net/9mbjhnpf/13

@Poke I feel you. Sometimes in my work building the ACs just stop working out of nowhere, or a whole room suddenly loses power.
 
@J.Sallé my docking station is only half working
one monitor, etc
 
@Poke wow that's weird
@mbomb007 what are the second/third icons? And the fifth icon on the last row?
 
@cairdcoinheringaahing Why doesn't this work?
 
can anyone get codegolf.stackexchange.com/a/157264/9206 to work in octave? For me it prints out the matrix and then a couple of minutes later quits

@WheatWizard I would participate in a Prolog learning room if it were created
