I love Funky for how ugly it can be.

Destructible Lemon

is there a proof that dodos is turing incomplete?

ATaco

It always halts, which is provable.

Destructible Lemon

because you could increase the length of the tuple? actually now that i think of it, that doesn't work

i was thinking that you could grow the tuple, but you only have a set number of distinct grows that you can use, equal to the lowest number in the current tuple

why is there a file in the dodos repository that just says dodos.py

Neil

12:30 AM

no primality tester in Dodos yet?

Destructible Lemon

not sure that's even possible, neil

Christopher

@Mr.Xcoder you can just send it to me

ATaco

I think it might be possible to prime test, and I want to try.

Dennis

I'm convinced it's possible. Primality tests use only bounded loops.

ATaco

TacO Can prime test, and that has similar mathematical limitations.

Christopher

12:37 AM

@Dennis Dodos?

Dennis

Dodos.

Christopher

Dodos?

Pavel

It's a language

It's not turing complete but actually extremely interesting

Christopher

@Dennis did you get the bounty yet?

Dennis

What bounty?

Destructible Lemon

Mar 8 at 3:03, by Conor O'Brien

CMC: Design a language such that the language is decidable under the halting problem. Make it as generally usable as possible. (I might bounty an impressive answer!)

from what i've heard, dodo is quite impressive

Dennis

I'm not sure what that was referring to. I mean, how do you bounty an answer to a CMC?

ATaco

12:44 AM

Wait, But TacO did that before that CMC.

Destructible Lemon

isn't there a design a language or something?

i'm sure Conor can figure something out

maybe bountying one of your dodos answers

ATaco

Honestly I feel kind of cheated.

But then again, it's not very usable, being a 2D tacit esque language.

Dennis

I'm not very familiar with TacO. Why would it not be TC?

Or rather, how is the halting problem solvable for TacO?

Christopher

shoot i had a question for dennis but forgot

ATaco

TacO has constructs for looping, but the only way one can loop is a finite amount of times, there is no method for looping an infinite amount of time.

Well, it's possible to throw the program into an infinite loop, but that's a bug and is easily predictable.

It's possible to loop through all elements in a list, but it's not possible to, within that loop, append elements to the list causing infinite looping.

Dennis

12:57 AM

What prevents me from using ? to go in a circle?

ATaco

Chains cannot self-reference.

They can cross over eachother, but they cannot reference thesmelves as a side-effect of how I compile.

Dennis

An unmatched " seems to create an infinite loop.

ATaco

Yep, that's the bug.

Dennis

Right.

ATaco

I uh, never got around to patching it.

Dennis

1:03 AM

I must ask: what is a Taccing language and what is Arithmatic?

ATaco

Arithmatic is an obvious misspelling of Arithmetic that i do consistently, and the reason TacO is Tacit is due to the fact that all symbols are functions which takes more functions (chains) as arguments, but programming in TacO does not accurately reflect the thought process one would normally use in a better Tacit language such as APL or Jelly.

Downgoat

Question: so for VSL I am thinking about static inheritance and how that should work. Should static dynamic dispatch be a thing?

What I was thinking is if you have a static method you could call it using Self.staticMethod()

and if that method using that Self.whatever got inherited, Self would then refer to the inherited class

Dennis

@ATaco So taccing = tacit.

ATaco

Yes.

My grammar and such is noticeably bad.

Nick Clifford

1:30 AM

@Downgoat reminds me of the Self type in Swift, although that's generally only used for protocol conformance

I have a dilemma^H^H^H^H annoying situation. I want to design a language, but I don't have any good fresh ideas for a language.

Destructible Lemon

that's not a dilemma

that's just an annoying situation

bkul

fair enough

Destructible Lemon

@bkul i had that issue, but i recently had an idea, and it was based around vague ideas i had, but the main thing that eventually helped me was designing it for a challenge to compile it to bf

a challenge which hasn't been made yet, by the way

@bkul do you have any ideas at all? like, do you want to make an imperative language?

Conor O'Brien

any java gurus in here?

user202729

@cairdcoinheringaahing I know, I often reread the messages and fix spelling error if I have time.

@ConorO'Brien What's your question?

Destructible Lemon

2:29 AM

@bkul I was thinking just now about making a language designed to compile/be interpreted by brain-flak

Conor O'Brien

Are classes in java able to access private variables of other instances of the same class when passed as a parameter?

public class Foo {
    private short x;

    public Foo() {
        x = 3;
    }

    public int compareTo(Foo other) {
        return x - other.x;
    }
}

user202729

I think yes.

Conor O'Brien

why ?

ASCII-only

Yes.

Because Java is bad and does no things

user202729

@ASCII-only ...?

Conor O'Brien

2:30 AM

@DestructibleLemon I've been thinking of a language that compiles to brain-flak too, tell me if you plan on pursuing that

Destructible Lemon

why do you need private variables?

ASCII-only

@ConorO'Brien mostly so copy constructor-y things work

Destructible Lemon

@ConorO'Brien what sort of ideas have you had? I haven't thought of anything specific

user202729

@DestructibleLemon To tell others that "plz dont access this".

Conor O'Brien

@DestructibleLemon all variables should be private by default because ^

Destructible Lemon

2:31 AM

oh ok

ASCII-only

Also it's against OOP but they do expect you to be able to decide whether you should access private variables

user202729

But, they still can if they try. (reflection etc)

ASCII-only

@ConorO'Brien Or protected

@user202729 It's slow, plus if they really want to do that then why stop them

Conor O'Brien

@ASCII-only well that didn't work

Destructible Lemon

ok so, for my brain-flak language, i think i will need to implement at least one thing significantly different from the brain-flak language

Conor O'Brien

2:32 AM

unless it throws a runtime error e_e

Destructible Lemon

for example, having variables rather than a stack as the main data store

ASCII-only

@ConorO'Brien hmm?

Conor O'Brien

@DestructibleLemon my idea of compilation would be to write a convenient-ish language like pseudo machine code, then abstract from there

ASCII-only

@ConorO'Brien no i meant they can be protected if you want subclasses to access them

Conor O'Brien

@ASCII-only oh. so there's no way to prevent cross-class sharing ?

Destructible Lemon

2:33 AM

I haven't even written a quarterstaff to bf compiler yet

ASCII-only

@ConorO'Brien there's a compiler that does that

@ConorO'Brien don't think so

Destructible Lemon

I think i'll publish the challenge this weekend or something

Conor O'Brien

@ASCII-only strange, ok

but cool, now I can forget about getters and setters for a few months

bkul

@DestructibleLemon My most coherent idea is a functional concatenative scripting language but it's kinda wonky

Destructible Lemon

haha i'm not really sure what that means

Dennis

Dennis

Destructible Lemon

things to think about when including things in a language: minimalism, not being ridiculously complicated, and interesting mechanics, in reverse order of importance, imo

Conor O'Brien

> The Divide Or Surrender paradigm doesn't such nonsense.

Destructible Lemon

include something if it contributes to the language having interesting mechanics. if not, include it if the language programs get ridiculously tarpitty without it. otherwise, remember that minimalist languages tend to be more elegant, and you can do without an add command if you have a subtract command

Conor O'Brien

2:40 AM

missing word perhaps? on the docs

Destructible Lemon

@ConorO'Brien i was thinking that was like an affectation

like "i think not"

Dennis

I don't remember what I wanted to write, but I think it was allow such nonsense.

ASCII-only

@ConorO'Brien getters and setters are annoying

Destructible Lemon

also i forgot to mention the feel of the language, because sometimes the language being a bit more fully featured contributes to the way it feels (for example, ><>, which could probably do without some of the commands, but the way it feels means that it's better with "unnecessary" commands)

Conor O'Brien

@ASCII-only yeah. I want to write a language which compiles to java that's actually sane

ASCII-only

2:42 AM

I like C#'s "you can do a getter but nobody will know the difference" better

@ConorO'Brien Just use .NET Core :P

Conor O'Brien

I like ruby's attr_reader and attr_accessor etc.

bkul

I think the presence of java causes madness so that might not be possible

ASCII-only

oh look warframe (lotus?) thing

Destructible Lemon

ok so, we've seen languages where the turing completeness is based on quining. what about languages where the turing completeness is based on other stock problems?

ASCII-only

I like C#'s { get; set; } better

Destructible Lemon

2:46 AM

cat for example. no idea how that would work

ASCII-only

because you can tell really easily if there's an accessor and/or mutator

Conor O'Brien

@DestructibleLemon which languages for #1 are like taht?

Destructible Lemon

esolangs.org/wiki/Muriel

idea: language where you run the program on the program text, then do the same again with the output from the program, or something

basically, cheating quine language, i guess

ASCII-only

sure but imo there are already a lot of source-is-data and/or source-replacement languages

Destructible Lemon

hmm

Conor O'Brien

2:59 AM

not as many as bf derivs :p

user202729

That's not nonsense! That just allow the language to be Turing Complete!

Conor O'Brien

XD SO TRUE

Οurous

What about something that rewrites the behaviour of its commands.

Conor O'Brien

there's some bf derivs that do that iirc

Οurous

At an opcode level?

Destructible Lemon

3:00 AM

@Οurous i think one of those exists

(unrelated question: anyone else has a Ctrl button on a phone?)

ASCII-only

@ConorO'Brien sure but those are by people that go "oh hey i made an esolang yay"

Conor O'Brien

@ASCII-only I think I have a bf deriv or two, on another note

precursor to simplex: Mericuk

Destructible Lemon

3:09 AM

idea for a language: the data is a single string you can add characters to, but can never remove from

or perhaps that and a minimal accumulator that is used for figuring out what to store in the string and whatever

Dennis

@user202729 I do. I also have a tab and a compose key.

DJMcMayhem

That's a shame. I use it all the time, and I'd consider it a deal breaker

@MartinEnder BF with ! extension definitely exists, e.g. my interpreter in Fueue, as well as fungot's implementation in #esoteric on freenode. It's an easy way to handle it when implementing in a language with no file input. (Still, that reads its own source code though. Unless you reinterpret that BF extension as providing a string literal...)

Martin Ender

fair enough, but then the answer should link to one (which also correctly splits on the first ! and ignores additional ones). but reading the source code is the bigger problem.

then again "reading the source code" is kinda fuzzy anyway, because of precisely that "reinterpretation" argument.

"-based Befunge quines and g-based Fungeoid quines aren't really all that different, but somehow we only accept the former.

(My target audience is literally a bunch of CS majors who have a decent amount of experience... a normal group of people would just figure out a way to bypass the puzzles altogether.)

So I've made 2 puzzles so far. The 1st was easy because I wanted to guarantee that they could solve it.

So I used a Vigenere cipher, but it lasted literally 10 minutes before someone was able to use computer assistance to crack it.

user202729

CMP: Do you remember if Jelly use £ or ₤?

@user202729 Actually, no.

PhiNotPi

So for the second puzzle... I threw in everything I could to make it legitimately difficult. And by "everything I could", I couldn't actually throw too much stuff in because there's a fine line between "hard" and "literally unsolvable."

caird coinheringaahing

So I guess there's two ways for me to go with this conversation: either (1) challenge TNB to a puzzle. Or (2) tell y'all the complete method I used so we can talk about the best ways to crack it.

user202729

CMP: (1) or (2)?

PhiNotPi

or (3) not enough interest at this time.

caird coinheringaahing

I'd say (1) for a bit, then if no one cracks it, go for (2)

Poke

^

is it supposed to be solvable without the use of a computer

PhiNotPi

TBH it is almost certainly not. Hopefully doesn't require brute-forcing, though.

Computer assistance is what allowed people to crack the Vigenere cipher in 10 minutes.

But I think this puzzle will require a decent amount of thinking and some linguistic-type attacks, it is not enough to just try brute-forcing popular methods (because my exact method is custom although the technique is not).

I've always wondered what exactly takes up so much space for Mathematica, so I ran du on it and more than half of it is docs

Conor O'Brien

If anyone is interested, I've semi-documented Attache here

Pavel

I also discovered that Mathematica has interfaces for Bing and Google search, for Google Contacts, for Chat, for Flickr, for Yelp, for Twitter, for Fitbit, for SMS, for Dropbox, for Reddit, and a bunch of other stuff

I wonder what it does with all of them

J. Sallé

@Pavel built-ins. Built-ins everywhere.

It has a built-in to detect if something is a goat. Thus, I'm not surprised anymore by what it has as a built-in.

Pavel

@AdmBorkBork It has general image recognition builtins. One of the objects it is able to recognize, amont many thousands of others, are goats.

AdmBorkBork

Yeah, tis what I said, no? ;-)

Q: What happened to my chat room?

Some time ago, I created a chatroom for the Reflections language. Now, I can't find it, and if I click the link on the Reflections page, it's not found. Has it been deleted? Why?

Q: What is code length?

An interesting conundrum has arisen in relation to the bonus I offered for APL solutions to An Ant on a Cube. It's an old challenge that requires a "named function", such as a lambda assigned to a variable: f←{...} - that is 2+ the code length we normally consider valid for most golfing challenge...

oh wow, Java REPL is a quite good programming language for golfing

i wrote a 5 byte solution to printing 2014 without any digits in a source code

although i suppose the challenge is quite easy so it's not a big deal

AdmBorkBork

Dang, that's quite a bit shorter than the 11-byte PowerShell solution. What is it?

xfix

+'ߞ'

quite boring honestly

AdmBorkBork

Ah, basically the same, except I need to stick a [char] cast inbetween.

xfix

i wonder if using a Tab key is a legit strategy for Java REPL codegolf however

i mean, you can write i[TAB] instead of int, for instance

dzaima

@cairdcoinheringaahing really the ＋ built-in is string append (even JS has that :p), it's just that Canvas treats mutliline strings as multiple lines of strings. As a result, there is no built-in for adding "abc\ndef" and "123\n456" to abc\ndef123\n456 as, while looking at the inputs as multiline strings, it doesn't look pretty. And × is just reverse join, I'm pretty sure many other golflangs have that

xfix

8:28 PM

HashMap is Ha[Tab]M[Tab] (by the way it's cool that java.util is automatically imported)

although i wonder if using REPL keybindings is a legitimate strategy

dzaima

@xfix if you count the language as the editor, I'm pretty sure that should count. After all, Vim is a commonly used language here

IIRC there was a meta post for using editors as languages somewhere too

xfix

it's Java REPL in this case, jshell

|    import java.io.*
|    import java.math.*
|    import java.net.*
|    import java.nio.file.*
|    import java.util.*
|    import java.util.concurrent.*
|    import java.util.function.*
|    import java.util.prefs.*
|    import java.util.regex.*
|    import java.util.stream.*

oh, it imports quite a lot, nice :)

but also not so nice, because it means more conflicts when you tab, oh well

for instance, H[Tab] won't work, because Http classes

I'm beginning to wonder, are you two friends IRL or do you just like sharing stuff with each other?

quartata

well let's see

they're about 5,800 miles apart

so it depends on your definition of IRL

Conor O'Brien

(for something completely different) what is that avatar

Riker

@ConorO'Brien uncultured swine

@quartata hey who knows, they could have grown up together or something

@ConorO'Brien I changed it to something else Pokemon-related just to annoy you

Riker

it's a pokemon rival :p

Conor O'Brien

like ik what it is but why

quartata

why not

@quartata I clicked your avatar and this window thingie exploded

Riker

ETHproductions

I had to zoom out to 50% to see the big version of the avatar, which completely defeats the purpose of clicking on the small version :P

Riker

ah yes, the german "Winderferthingie"

quartata

@ETHproductions what?

oh

all the rooms

Riker

@ETHproductions only 49 rooms

quartata

sorry

Riker

10:29 PM

but @ETHproductions lol no I do not know any sentient slowworms irl

(assuming flawr is sentient x-files theme plays)

flawr

@Riker maybe you do, but you don't know? :D

XD

On the topic of stacking things: I'm looking for an algorithm to determine the "most isolated point" of a finite set, maybe someone here can help: cs.stackexchange.com/questions/89411/…

</badsegway>

@flawr you know what? I should make a challenge on PPCG if I really want an answer.

Riker

@flawr isn't this a form of the taxicab problem?

flawr

googling teh caxicab probelm

Riker

10:36 PM

shortest route that passes through a set of nodes

i.e. bus's route through a set of stops

iirc it's NP complete?

flawr

no idea.

@Riker would this include this particular "edge" from the most isolated point to its closest neighbour?

Riker

I think so

I'm fairly certain the taxicab problem is just a iterated version of your issue

flawr

10:51 PM

added it as a challenge to the sandbox

Riker

@flawr

@flawr interesting to make that fastest-code
