@cairdcoinheringaahing about that... (cc @Mr.Xcoder)

recursive

@MartinEnder whoa...

ASCII-only

12:46 AM

:/ Does gmpy2 not have arbitrary precision reals

HyperNeutrino

@totallyhuman Fair enough. Probably going to remove it, though weird things are possible even in practical languages, it's just strongly discouraged by all standards. Preventing all weird things isn't really necessary by the language creator.

@cairdcoinheringaahing [^] But I definitely would agree that having that in the language is just asking for confusion.

Destructible Lemon

prime checker has been completed!

HyperNeutrino

@Adám That's the main thing I was thinking as well for a reason not to remove it. Sure, it might be bad, but that's the user's fault, not really the creator's.

@ASCII-only well Charcoal isn't designed to be a practical language :P

(though actually that means that a practical language should even less so have something like that... lol)

ASCII-only

@HyperNeutrino who said so

HyperNeutrino

@Stephen Python also happens to not have inline comments

@ASCII-only TIO lists it as recreational and Dennis is always right (:P)

no but like it's specifically designed for ascii-art golfing... :P

ASCII-only

12:50 AM

@HyperNeutrino Doesn't mean it wasn't designed to be one

@HyperNeutrino verbose mode is a thing

HyperNeutrino

fair enough

ASCII-only

Although I should probably implement shunting yard for sane operators

CMP: Star or ping or w/e if you think Charcoal should have infix operators

HyperNeutrino

@ASCII-only verbose mode or golfed mode? (assuming verbose)

Destructible Lemon

10-?[-38a a a a a a a a a a>a10-?]a>b b[>b>d a>c c[1>c 1d>d b d(.>e|>d1>e)c]e f>f b1]2-f(.48|49)!

that's the prime checker

HyperNeutrino

@Adám well it would be 3 ** 4 (no space) which is 3 to the power of 4.

Destructible Lemon

12:52 AM

the main bug was not setting d to zero

ASCII-only

@HyperNeutrino verbose

Adám

@HyperNeutrino OK, so whitespace is ignored in multi-char operators?

HyperNeutrino

ok

yes I think so

@Adám no, whitespace just isn't allowed.

Destructible Lemon

would anyone be interested in an explanation of the primality check program?

ASCII-only

@HyperNeutrino it's just way too slow in golfed mode plus not that useful I think?

HyperNeutrino

12:53 AM

(except for stuff like += because of the way it's parsed (N/A as of now). similar to funky)

Adám

@HyperNeutrino Then your answer should have been "an error".

HyperNeutrino

@ASCII-only yeah I didn't think infix would be particularly useful in golfed mode. but yeah I would say probably add it to verbose

@Adám fair enough

Adám

@HyperNeutrino Then is +/*comment*/= an error?

HyperNeutrino

@Adám no

in fact + /* comment */ = would be fine too (in theory)

Adám

@HyperNeutrino Then I'd say for sanity and consistency, no multi-char operators should break because of whitespace or comments.

@HyperNeutrino How about 3 + / * comment * / 4 ?

HyperNeutrino

12:55 AM

@Adám that would be fine

@Adám well the thing though is that += is more of two operators (assign, plus) combined together, but ** isn't two multiplication operations combined

Adám

@HyperNeutrino But / * is certainly a single token.

HyperNeutrino

wait sorry I didn't see the spaces there

no actually that would be an error because /* starts a comment and not / *

sorry

Adám

@HyperNeutrino Ugh, the pain of multi-char tokens. I'll just stick with APL's single-char tokens — well, almost. Unfortunately we do have four two-char tokens ⍨

Destructible Lemon

why is everything in proton floats

HyperNeutrino

@DestructibleLemon they're actually mpmath.mpf objects

Destructible Lemon

1:00 AM

still

HyperNeutrino

or with --sympy, they're sympy.Rational objects

Destructible Lemon

print(3 + 4) prints 7.0

HyperNeutrino

yes

I mean at this point I kind of want to entirely stop working on either of my most recent languages. It takes too much work to maintain them and actually keep them developing and I can't really commit that much time especially if/once school gets busier.

Destructible Lemon

this is why you make minimalist languages

less work

ASCII-only

@HyperNeutrino >_>

HyperNeutrino

1:05 AM

wat

Adám

@DestructibleLemon Yup, or like I did, make thin covers for existing stuff.

HyperNeutrino

I've been considering making Neutrino stack-based because it's so much easier but I just don't want to because I want it to be as golfy as possible; making yet another semi-decent golfing language that can't win challenges isn't my goal. I want to be able to tie and beat Jelly consistently in math/list-manipulation focused challenges

Destructible Lemon

one of my recent updates to a language removed commands for being too golfy i guess

is one way of looking at it

ASCII-only

@DestructibleLemon wait wat

Destructible Lemon

i removed two commands to make the language simpler, is probably a more accurate way of looking at it

ASCII-only

1:13 AM

@HyperNeutrino on the other hand there's me, I added features that have 0 things to do with ASCII-art whatsoever because I was bored >_>

Destructible Lemon

whereas @HyperNeutrino appears to be doing the opposite, which takes a fair amount of work

make minimalist languages!

it will be good!

HyperNeutrino

I want to focus on a major project and do it well instead of making a ton of tiny things that aren't really significant, but at the same time, that takes "a lot more time"

Destructible Lemon

then again it's kind of hard if you don't have any inspiration

HyperNeutrino

realistically, it's just that the time/project ratio is a lot higher, but the overall time spent is not any more

really I just have a terrible attention span + ability to hold on to interests for more than like 3 days >_>

Destructible Lemon

some of the "expressions" in my language look like infix but they aren't

HyperNeutrino

1:17 AM

Jelly dyad-nilad chains look infix but they aren't :P

Destructible Lemon

10-var looks like 10-var but it's actually var-10 because it's (0 being the initial value) (((0)+10)*-1)+var

HyperNeutrino

...why

recursive

addition is implicit?

Destructible Lemon

- = multiply value by -1

HyperNeutrino

CMQ how can I stop my computer from randomly disconnecting from the internet on its own (fedora 27)

Destructible Lemon

1:19 AM

and integer means add integer to value, and a variable means the same thing but with its stored value

@HyperNeutrino uhhhh post on a fedora forum about how bad fedora is? i read somewhere that works

HyperNeutrino

wait you mean just post about fedora being bad and it will stop? o_O

Destructible Lemon

no because people will want to prove you wrong

HyperNeutrino

mhm..so your point is...?

Destructible Lemon

nevermind

recursive

There's a meme that the only way to get help with linux is to post on forums about how linux can't do that thing.

Then a bunch of people will provide detailed instructions about how to do that thing.

Whereas if you just asked, so the meme goes, you'd just get RTFM.

HyperNeutrino

@DestructibleLemon your spec about reading input is weird and unnecessarily complicated. you could just say that , returns 0 if at EOF and otherwise reads one byte from the standard input stream and modifies the tape value to that

Destructible Lemon

it's not like that exactly though but yeah i could just say that couldn't i

HyperNeutrino

it is a lot simpler

It seems like there's some formatting missing or something. I can't make sense of it.

Destructible Lemon

@recursive yeah. i'm removing that part now

HyperNeutrino

that was stupidly painful

i did list(itertools.repeat([0, 1])) in a shell and then it froze

and Ctrl-C doesn't even work, it just starts taking all RAM existent

so I had to swap to tty2, try to log in from there (which took 8 years because it kept timing out)

and then kill the shell, which didn't even work for like 2 minutes

and my computer still barely works

ASCII-only

@HyperNeutrino O_o 8 years

HyperNeutrino

@ASCII-only no exaggeration /s

@HyperNeutrino solution: force shut down

HyperNeutrino

@HyperNeutrino Just shut it down, we'll see you in 8 years' time :P

Well that's unfortunate.

@MartinEnder My Fueue is a bit rusty I guess... I have the three implementations listed on the page and think I may have mostly used the C one but I'm not sure. However I made a modification to it to remove a silly size limit. I just put a link to that version on the wiki.

Ørjan Johansen

Ørjan Johansen

@Pavel After a bunch of silly diff trouble because the versions had different newline conventions, I conclude the fixes are already in the official version.

Pavel

Ah

Ørjan Johansen

@Pavel Ah yes, probably just GHC changing.

That implementation may be from before the great Monad/Applicative/Foldable/Traversable upheaval.

Dennis

3:04 AM

Yes, I just had to hide one of the length from Data.Foldable and Data.Sequence. I hope I hid the right one...

ASCII-only

@Downgoat @userscript people should we add some of the suggestions here

Ørjan Johansen

@Dennis I suspect the Foldable one is more general, so if it compiled, it probably works.

Dennis

I tried with both; both compiled.

Foldable is the one I hid. :/ github.com/TryItOnline/fueue/blob/master/fueue.hs#L11

Pavel

I'm guessing if they both compile there won't be issues.

I mean, how different can implementations of something called length be

Haskell is statically typed so if the only difference is in which types are supported (which is the most likely case) then you'd have a compiler error if you hid one that didn't work for all cases it's used in.

Ørjan Johansen

3:20 AM

To be more precise, Data.Sequence's code contains length = length which defines the Foldable one as identical to its own.

don't use #FFF for foreground either. Use rgba(255, 255, 255, 0.8) and perhaps softer fonts/colors

@Mego Yey \o/

May I ask you what a loopholes is ?

HyperNeutrino

2:20 PM

@DIDIx13 a loophole is basically an ambiguity or unspecified thing in a challenge that is abused. by default rules, disallowed on all challenges here

caird coinheringaahing

Such as outputting "the array sorted" when the challenge asks you to "take an array as input and output the array sorted"

Q: Loopholes that are forbidden by default

I've been thinking for a while that this would be useful, and some recent discussions have strengthened that belief. There are a number of standard loopholes which experienced question-setters seek to explicitly close. However, inexperienced question-setters may unintentionally leave them open, ...

@HyperNeutrino Thanks for your explanation and thanks @cairdcoinheringaahing for the example :)

For most online programming contests, I registered and then forgot to participate. So...

DIDIx13

@user202729 I'm not good enough for code-golfing in my opinion so I won't participate either x)

Maybe in C# I know few tips who can save some bytes

user202729

I was replying to Mego's "Google Code Jam registration is open"...

DIDIx13

@user202729 Me too ^^

Any final thoughts before I post up Lonely Primes?

Seems fine to me

@user202729 we've historically had quite a lot of involvement from PPCG. Many of the users here are friends with each other on the site, and we compare scores, talk about problems, etc

@user202729 I'm pretty sure that's just a TNB thing actually

@Mego What's the level of experience you should have to participate in the code jam?

user202729

@Mego Why don't you include a link?

@Pavel Why do you need any experience at all to participate?

Pavel

Well, I'm guessing that someone who's only ever used HTML before in their life wouldn't be very good.

user202729

@Pavel ... you only need experience to get a high score (/rating/ranking/number of problem solved).

... The time doesn't look very good for me.

> The Qualification Round begins on Friday, April 6 at 23:00 UTC.

Pavel

@user202729 There's a big difference between problems that are this hard and puzzles that are this hard.

user202729

So...? I think I was talking about codejam?

Q: Some Lonely Primes

I know, I know, yet another primes challenge... Related A lonely (or isolated) prime is a prime number p such that p-2, p+2, p-4, p+4 ... p-2k, p+2k for some k are all composite. We call such a prime a kth-times-isolated prime. For example, a 5th-times-isolated prime is 211, since all of 201, ...

@user202729 Right. I was wondering how hard the problems are

user202729

There are past contests for practice.

Q: Convergence of a Markov Process

Challenge Given a markov process represented as a left-stochastic square matrix (columns sum to 1), return the matrix to which the markov process converges. Basically, you want to keep multiplying the matrix by itself until the result no longer changes, so you want to find a matrix B given input...
