(perl5) Is there any way to:
1. print *anything* to stdout shorter than 7 bytes
2. error out in eval

quartata

01:59

@NewSandboxedPosts is there a close reason for "'cia propaganda".

Quintec

@quartata Don't deny your involvement in this

Pavel

@user202729 say'42', requires the -M5.10 flag (or a higher version)

say appends a newline automatically

You could also use the -p and -n flags for super short io, see perldoc perlrun

quartata

i will deny it

if you could first just tell me what the word "this" is that would be very nice. thank you.

Pavel

@quartata I suspect he refers to codegolf.meta.stackexchange.com/questions/2140/…

quartata

if i were a kgb agent, i simply would have stopped the soviet union from falling, thus avoiding lots of potential issues for it down the line. i dont know why they didnt think of this

ASCII-only

02:19

@ETHproductions i've found them generally on their licenses or websites

@LuisfelipeDejesusMunoz you can always ask the authors of those languages :P

@Dennis yeah. especially because being the one that wrote it, it's generally still fresh in their memory

ETHproductions

@LuisfelipeDejesusMunoz 𝔼𝕊𝕄𝕚𝕟 is the only other one I know of.

Dennis

Tfw your new headphones finally arrive and you have to charge them for sixteen hours.

Phone chargers spoiled me.

Pavel

@Dennis Is this related to your power grid problems

My bluetooth headphones charge fully in like half an hour and last me several weeks

Dennis

No, the manual says 16 hours.

ETHproductions

TeaScript was actually the first, and it inspired me to write the interpreter for Japt (I'd already had the idea but hadn't implemented it), then 𝔼𝕊𝕄𝕚𝕟 came in around the same time as Japt. We had a mini-competition going on between the three languages for a few months :-)

ASCII-only

02:27

then everything but japt basically died :P

@ETHproductions btw why does japt have so many todos :(

ETHproductions

Case in point, TeaScript has no surviving interpreter :-(

ASCII-only

it... what O_o

Pavel

@Dennis That's... really weird

quartata

wasnt there a fourth JSGL

uhhhhhh

ETHproductions

@ASCII-only are you looking at Japt v2--wait, nevermind, I see what you mean. I can't implement them all you know :P

ASCII-only

02:29

@ETHproductions can't?

also hmm

maybe i should make charcoal transpile to js :P

ETHproductions

I actually only have 3 reserved letters left for array methods

ü, ý, and þ I believe

ASCII-only

oh :|

ETHproductions

Of course, Japt doesn't use 65 of the 256 bytes (outside of compressed strings)

ASCII-only

0/10

ETHproductions

and even in compressed strings, 0xF0-0xFF are still useless

consequence of the choice of compression library

ASCII-only

02:31

shoco?

quartata

its kind of interesting how people were upset about golfing languages in gneral and there were so many and then the introduction of an even more flexible golfing language kind of took care of those problems

ASCII-only

even more flexible?

quartata

gelatinous

ETHproductions

lmao

Dennis

@Pavel It comes with NiMH batteries. That's probably why.

ASCII-only

02:33

@quartata how did it take care of the problems tho

Pavel

Ah

Dennis

16 hours is for the first charge. It's 8.5 hours after that.

quartata

well we kind of only have two general-purpose golfing languages in consistent use now

ETHproductions

@ASCII-only right, it dedicates 64 bytes (0x80-0xBF) to 2-to-1 compression, then 32 (0xC0-0xDF) to 4-to-2, 16 to 8-to-4, and so on. 8-to-4 is already buggy beyond use, and when you get up into 16-to-8 it starts somehow entering an infinite loop when attempting to decompress the string.

ASCII-only

you what

what is this terrible compression :/

ETHproductions

02:34

Now that I think about it, I don't think 0x00-0x1F are used in compressed strings either :P

It's not terrible, it's actually really good at compressing strings of lowercase letters.

nothing else though :(

ASCII-only

hmm. actually. maybe it's about time for charcoal v2?

Quintec

"somehow entering an infinite loop when attempting to decompress the string" um ok completely normal

ASCII-only

@ETHproductions ~~compare it with charcoal's~~

ETHproductions

A: Shortest Code to Legitimately Slack Off

Japt, 2 bytes `ÿ You can test this online here, but I wouldn't recommend it as it will freeze your browser. Explanation Japt uses the shoco library for compressing strings. A backtick tells the compiler to decompress everything until the next backtick or the end of the file. Each byte does t...

ASCII-only

also. charcoal still doesn't have dictionary compression because i'm not sure what would be a good way to do it

ETHproductions

02:36

Hey man, I haven't even planned dictionary compression for Japt v2 yet

Pavel

@ASCII-only steal jelly's

ASCII-only

@ETHproductions apparently shoco is only a dictionary compressor tho?

basically

user202729

@Pavel None works with A Pear Tree :(

ASCII-only

@Pavel hmm. well charcoal does have brotli tho

user202729

(I was tryimg to crack ais523's cop submission)

Quintec

02:37

@ETHproductions Darn, I was hoping for an interesting explanation as to why. :P

ETHproductions

@ASCII-only It's based on the english dictionary, but isn't in itself a dictionary compressor in the traditional sense. I guess you could still consider it one, just mapping sequences of bytes to specific sequences of lowercase letters

@Quintec Maybe one day I'll dig into that awful minified source code and find out what exactly goes wrong :P

Quintec

That sounds like torture

Pavel

@ASCII-only If we don't care about speed and memory requirements (which we don't because code golf), PAQ: github.com/hxim/paq8px

ETHproductions

It's minified C compiled through Emscripten to JavaScript and then minified again

ASCII-only

@ETHproductions just compile it yourself

with the newest stable version of emscripten

Pavel

02:40

PAQ is like, the best compression

Quintec

Now that I think about it, a minified functional Java golf lang would be pretty cool.

ASCII-only

@ETHproductions github doesn't count????

Pavel

And it does in fact take under an hour to compress Hello, World!

Dennis

To how many bytes? :P

Pavel

I don't remember

I think it made my entire computer unresponsive and then I just nuked it

ASCII-only

02:42

:|

Quintec

So into 0 bytes!

Dennis

But not with HW, right?

Pavel

I actually tried it with a pdf of the core rulebook of The Dark Eye

Which is substantially longer

ASCII-only

@quartata two???

Pavel

@Quintec What about Java makes it particularly good for functional programming?

ASCII-only

02:44

is everything other than japt and jelly dead :P

Quintec

@Pavel Absolutely nothing, but java functional programming is cool ^.^

Pavel

@Quintec Have you tried other languages that allow functional programming

It's a lot cooler than Java's way of doing it

ETHproductions

Interestingly I just noticed Alex A. has ported shoco to Julia

Pavel

Well, C++ functional programming is probably even worse, but other than that

quartata

@ASCII-only i was actually thinking jelly and matl

ASCII-only

02:45

huh, MATL

quartata

sure you have your specialized stuff but

ASCII-only

well. not surprising. it has industry grade documentation :|

Quintec

I would say APL is rather alive

Pavel

APL isn't a golfing language though

ASCII-only

but... are 05AB1E, Japt, Actually and the like all dead. also ^

Quintec

02:46

@ASCII-only Are they actually dead

ASCII-only

APL and derivatives are not golflangs

quartata

@ETHproductions alex has ported everything

ETHproductions

true

ASCII-only

@Quintec :|

quartata

osable is dead last i checked

Quintec

02:46

Hey, someone was going to go there sooner or later

ETHproductions

wait, when did 05ab1e die

ASCII-only

@quartata @ETHproductions they're wrappers not ports

Pavel

Brachylog is really good at squares and that's all I know about it

quartata

i know. its just ffi.

Pavel

ffi? Frabjous Fractran Interpreter?

ASCII-only

02:48

@Pavel also amazing at things prolog is good like. e.g. reverse fibonacci

quartata

foreign function interface

ASCII-only

also i remember how much time i wasted on this >_>

oh yeah @Dennis when are you planning for jli to be a thing :P

Dennis

Not sure yet. Not enough time.

@ASCII-only O5AB1E and Japt are actually pretty close to Jelly.

Luis felipe De jesus Munoz

@ETHproductions it has =D

ASCII-only

@Dennis *05 :P

Dennis

02:54

Right

ETHproductions

@ASCII-only I think Emscripten actually might minify it itself, since it can't recover function and variable names from the bytecode, right...?

ASCII-only

@Quintec yeah. why not just use a purely functional language like haskell or its derivatives

Quintec

Because I don't feel like learning a new language, lol

ASCII-only

@ETHproductions possibly. but i mean it's possible the bugs have been fixed with a newer emscripten

Luis felipe De jesus Munoz

@ETHproductions vihan.org/p/TeaScript

Quintec

02:56

Something about Java's way of using OOP to implement functional programming makes it horrible and beautiful all at once

ASCII-only

@Quintec no... i mean just use... idk. haskell? common lisp? clojure? parenthetical?

@Quintec most certainly not. just horrible and terrible all at once

Quintec

nononono

ASCII-only

seriously. even C# is way better

ETHproductions

@ASCII-only chat.stackexchange.com/transcript/240?m=47334830#47334830 and Japt was also at Sep 20 when this was posted

Pavel

@Quintec Just learn C#, it's like Java but with sane functional programming capability

Quintec

02:58

Help I'm being persecuted for my beliefs

Pavel

And when I say it's "Like Java", it's really like Java

You can pick it up in half an hour

ASCII-only

except golfier ofc

like no extends and implements for one

@Quintec yes bc javaism is the programming equivalent of satanism

ETHproductions

@LuisfelipeDejesusMunoz brb adding link in golfing-langs :D

Pavel

@ASCII-only Also is and not Instanceof, int? and not Integer, [0] and not .get(0), etc.

ASCII-only

and C#7

Pavel

03:01

Yes

and tuples

Shieru Asakoto

also availability to overload operators

god bless C#

ASCII-only

oh yeah that's a really important improvement

tbh i'm more surprised java doesn't let you do that

Pavel

That's not really a golf feature except when it's been done beforehand by library designers

C# has some lovely non-golf features, like structs, properties, async, linq

ASCII-only

i still think linq is weird

Pavel

What part of it is weird

ASCII-only

03:03

the fact you can write a sql query in c#

like... var foo = select property from data where conditions

Pavel

You can just use the method form instead of the keyword form

user202729

Any way to shorten tio.run/… ? Assune:

Pavel

@ASCII-only The designers thought it would make code harder to read. The JVM does support it however, and String overloads +

ASCII-only

oh yeah var is good too. java's finally catching up

user202729

1. The header is unchanged

Shieru Asakoto

03:04

When dealing with BigIntegers I MEAN I JUST HATE HOW JAVA MAKES IT VERBOSE AF

even js BigInts uses operators

Pavel

Java does have BigDecimal

C# is just stuck with normal, 128-bit decimal

ETHproductions

ES2020 makes BigInts in JS easy as pie, just type 1n and boom, a BigInt appears

No BigDecimal though

user202729

2. It's necessary to have an expression that evaluates to the source code

Shieru Asakoto

Oh its confirmed ES2020?

ETHproductions

(not yet, I'm assuming things lol)

Shieru Asakoto

03:06

iirc it's still in Stage 3 because Firefox is still on its slow pace implementing BigInt

ETHproductions

still at stage 3, tests ready but not merged

oh, does it only make it to stage 4 once all major browsers have an implementation going?

Pavel

Oh, we also have nuget in C# land

Shieru Asakoto

iirc two different implementations?

ASCII-only

@Pavel and chocolatey :P

Shieru Asakoto

but so far only V8 has finished implementation

Pavel

03:08

Now, Dennis could tell you all the reasons why nuget is not the most amazing language-specific package manager, but Java...

user202729

52 bytes so far (sorry for interrupting)

Quintec

You can take Java away from my dead body

Pavel

Personally I think Nuget makes some really good decisions that make it a lot more usable than Pip or Gem or Cpan or whatever

ASCII-only

@user202729 damnit this is longer

Quintec

goes and hides in a corner

Pavel

03:10

@Quintec The first step to a better life is admitting you have a problem

ASCII-only

@user202729 not allowed?

user202729

49

@ASCII-only Yes, "expression evaluate to soirce code" is i,portant.

ASCII-only

@user202729 ???

user202729

I alsp tried various combinatiom of __END__/DATA, too long.

read $0 doesn't work because A Pear Tree.

7 mins ago, by user202729

2. It's necessary to have an expression that evaluates to the source code

ASCII-only

@user202729 wait wat

why though

Quintec

03:14

@Pavel But does C# have... thinks frantically uh... I don't know, multithreaded concurrent stuff?

ASCII-only

@Quintec yes, why

user202729

tio.run/…

Actually DATA is shorter but

Quintec

But is it good

ASCII-only

@user202729 ?

user202729

@ASCII-only I intend to use the src to do other things not just src

ASCII-only

03:15

@Quintec yes why

Pavel

@Quintec Way better than Java's

See async/await

user202729

@ASCII-only I intend to use the src to do other things not just print

ASCII-only

@user202729 wat

Quintec

java has those

Pavel

No as keywords

user202729

03:15

(as I said abv I was trying to crack ais' cop submission)

ASCII-only

@Pavel and threads too

Pavel

Like you can declare a function to be async and it'll automatically run on it's own thread when you call it

ASCII-only

@user202729 link pls

Pavel

And then you can await the result

ASCII-only

@Pavel oh wait yeah

also. lol, canvas, charcoal and bubblegum appear to somehow be tied for this challenge

Quintec

03:18

Time to write only java answers forever

ASCII-only

@user202729 oh i see. then no need to print

Pavel

@Quintec Here, look: tio.run/…

Shieru Asakoto

yield return in C# is just so good to write an async task especially when using Unity

Pavel

Also generators

Shieru Asakoto

In java you need to use threads, and boom RACE CONDITION

Pavel

03:24

Well you can't get rid of race conditions

Quintec

B-b-b-but CountDownLatches!

ASCII-only

oh @user202729 what even is <DATA>__END__

@Dennis aw :P

Pavel

@Quintec CountdownEvent msdn.microsoft.com/en-us/library/…

We have Events, too

You can also, more simply, await a list of tasks

Quintec

@Pavel That doesn't have encapsulation, I refuse :P

ASCII-only

@user202729 does this work

user202729

03:38

Ok, no...

The program must

1. On empty inpitm print something

2. On input nonempty, with -p0777, different from src, print something

3. on input eq to src, print nothing

'src code here'ne$_||die;print 1 would work

Reading DATA won't work b'c APT append a newline to end of source code.

Fortunately thanks to p0777 the whoke input is slurp at once.

ASCII-only

what happened to your typing :|

Shieru Asakoto

-p0777 is this permission?

ASCII-only

oh so no need to undef $/? @user202729

@user202729 so it's ok as long as newline is trimmed?

user202729

I think appending a newline and force scalar <DATA> would work.

@ASCII-only Yes.

ASCII-only

wait <DATA> not scalar???

@user202729 trim might work too???

user202729

03:48

@ASCII-only In print it isn't.

ASCII-only

but why print???

user202729

Because I realize I don't need it.

ASCII-only

also damnit perl 5.0 doesn't have print

user202729

Ok, it should work.

So seek*DATA,-47,2;<DATA>ne$_||die;print 1;__END__ with a trailing newlineshould work

but it's just too long already.

(note that APT append some code to the beginnung too, so seek with WHENCE 0 don't work as expected)

ASCII-only

how much code to beginning :/

user202729

03:53

More than100 bytes. It can be determined but don't save any bytes.

ASCII-only

seek*DATA,-47,2;print<DATA>ne$_;__END__ or something doesn't work????

or seek*DATA,-47,2;print$_ne<DATA>__END__ or w/e

user202729

@ASCII-only p0777 auto print. die is necessary when $_ eq src.

ASCII-only

oh

user202729

Or $_='' which is longer.

ASCII-only

if auto print then why need print at all????

user202729

03:55

@ASCII-only Without input no flag is given.

ASCII-only

oh true :/

and say doesn't work bc it's not >5.10 :/

wow Neil is really, really active :/

ETHproductions

Top 10 golfing langs: Jelly, 05AB1E, Japt, Pyth, Charcoal, Stax, Retina, MathGolf, MATL, Brachylog

user202729

@ASCII-only In my testing __DATA__ or END is necessary for DATA to be usable.

ASCII-only

04:02

oh :(

@ETHproductions when an ascii art golflang is 5th

and a regex one is 7th and an imperative one is 10th. there really are a lot fewer golflang submissions than we thought. or fewer golflangs than we thought

@user202729 oh yeah, regex how :/

user202729

Idk, /something/ may be shorter than $_eq'something'

ETHproductions

@ASCII-only Fun fact: there are only 71 GS2 answers

ASCII-only

even though it's one of the few golflangs on anagol :P

ETHproductions

GS2 gets a score of Oct 11, 2015 :(

ASCII-only

O_o wow

Bubbler

04:08

What, Japt is 3rd?

It's probably the only language that benefited from LotM

ASCII-only

common lisp looks like it gets around jan?

tcl about april

ETHproductions

@Bubbler I'm really lucky to have had Shaggy in the Japt community at that point, he did most of the advocating, and did a great job of it :-)

ASCII-only

clojure gets around feb

so surely golfscript isn't the 40th?

also @ETHproductions oi, perl 5 != perl 6

ETHproductions

and python 2 != python 3

or is the difference greater than that

ASCII-only

much, much greater

i'd say even greater than python 1 vs python 3

ETHproductions

04:14

@ASCII-only no, it's probably more like 50th-60th

Dennis

Python 2 and Python 3 have minor differences. Perl 5 and Perl 6 are completely different languages.

ASCII-only

XD yeah you're missing the mainstream languages. the ones i'vementioned and other ones. e.g. prolog

ETHproductions

ok, I'll see what each of the Perls get individually.

ASCII-only

looks at prolog result screen

ignore that one, that's just me bloating answer count

ETHproductions

Perl 5 is Jul 27

Perl 6 is Oct 26

so Perl 6 is still 3rd (tied with Jelly), Perl 5 is more like 26th

@ASCII-only yeah, with some languages more than others you have to be really careful how many answers you include. I'm already excluding answers on questions tagged polyglot, koth, or tips

ASCII-only

04:18

no as in look at the submission authors >_>

ETHproductions

K was one of the worst, surprisingly C wasn't too bad

@ASCII-only oh lol

Bubbler

C is one of the craziest when it comes to golfing IMO

ETHproductions

that's impressive that you managed 22 Prolog answers in a row xD

ASCII-only

tbh they were only on old, easy challenges that made it to the front page

add that to the fact basically nobody uses prolog anyway

ETHproductions

well, there are around 360 Prolog answers, and of your 24, 22 ended up in a spell where no one else was writing them

and 10 other users have used it in the 5 months since

user202729

04:24

Best without reading src: 68

Best with __DATA__: 48 (inreal code rplc 48 wt 49)

Is there a way to terminate program inside eval? (perl5)

Ok, apparently exit works but die doesn't.

Best with eval: 47 (actually 46 in APT)

but crc32 makes it 52 :(

ASCII-only

@user202729 can you remove the $ in $x

user202729

@ASCII-only Only in APT, and only 1 of them.

(the one outside string interpolation)

ASCII-only

@user202729 which means you can remove the one inside as well

user202729

Oh right.

44 eval(x=q["eval(x=q[$x])"ne$_||exit;print 1])

(not tested)

Hm...

ASCII-only

44???

user202729

04:37

@ASCII-only Yes, the backslash for escaping $ can be rm too.

ASCII-only

oh

user202729

would eval(x=q[/eval(x=q[$x])/&&exit;print 1]) (40) work?

(no, because $ and () are interpreted as regex metacharacter)

Any workaround? ...

Bubbler

$ looks fine since it's inside []

user202729

@Bubbler But [] will need to be somehow escaped too...

Bubbler

Yeah, that's the problem

user202729

04:40

Adding too much \ will destroy the advantage of regex,

and m'....' won't work b/c $x need to be interpolated.

Oh there is \Q.

ASCII-only

@user202729 wait that interpolates $x?

ETHproductions

Is there somewhere where I can download all answers (or even all posts) from PPCG?

ais523

@user202729 you don't need sprintf to write a quine in Perl/A Pear Tree, and it's one of the most verbose ways of doing it; my first A Pear Tree quine was a= "print('a=',repr(a),';eval(a)#r3TQJ')" ;eval(a)#r3TQJ (this also works in Python 3)

ASCII-only

@ETHproductions nope

@ETHproductions well. SEDE's weekly backups might work?

ETHproductions

SEDE will give me 50K at a time, I guess that will work

user202729

04:45

@ais523 I remember trying repr+"...", doesn't work too

ASCII-only

@ETHproductions no as in the db download

ais523

btw, I normally test A Pear Tree programs by sticking a #r3TQJ in the header, that string (followed by newline) has a CRC-32 of all zeroes

ETHproductions

@ASCII-only link? (I can't reply for some reason)

hmm, it's better now

ASCII-only

@ETHproductions archive.org/download/stackexchange

ais523

@ASCII-only I used to use it for PPCG, but it's so verbose :-( Nowadays I normally use Brachylog instead unless the program really needs to do things Brachylog is bad at

ETHproductions

04:47

last modified Sep 05, interesting

ASCII-only

wait damnit

@ETHproductions well for smaller sites you can just start from the data dumps and update data using SEDE

@ais523 a language being verbose doesn't stop people from answering in it :P just look at java

ais523

@ASCII-only yes, but part of my motivation for code golfing is learning about language: "how concisely is it possible to express this idea, what sort of language makes it possible to be expressive in the same way that, say, English is", so shorter program = more interesting

ASCII-only

also wait there's no a pear tree hello world yet???

ais523

there's one on TIO I think

ASCII-only

@ais523 english isn't concise btw >_>

@ais523 wait true >_>

ais523

04:51

it's just a Perl/Python hello world with a #r3TQJ stuck in front of it

to keep the CRC checker happy

ETHproductions

@ASCII-only in SEDE, do you know if there's any way to get the tags of the parent question given a question id?

ASCII-only

@ETHproductions parent?

someone really needs to add the rest of the TIO Hello, World! programs to codegolf.stackexchange.com/questions/55422/hello-world

@ETHproductions i'll look, brb

ETHproductions

@ASCII-only as in the tags of the question the answer was posted on

user202729

Hm. Use regex won't save any bye because \Q^$ is 4 byte long alteady

ASCII-only

@ETHproductions so given an answer id?

ETHproductions

04:53

well, I have all the data from the answer, including the id of the question it was posted on, and I just want to get the question's tags

ais523

now I'm glad I spent so much time golfing that A Pear Tree cop

user202729

@ASCII-only No....

ais523

not only did I have to golf it down to a pretty short length, I also had to try every variation of the program at that length to find one where I could slip in an ASCII CRC

user202729

@ais523 It's overgolfed for me :/

ASCII-only

@user202729 ?

@ASCII-only Sounds like answer spamming for me...

ASCII-only

well

someone has to do it sometime

@ETHproductions just work from the question ID then, seeing as you have it; no "parent" relationship needed

@ETHproductions data.stackexchange.com/codegolf/revision/927341/1152205/…

@ais523 nah it's easy and super fast either way

ETHproductions

@ASCII-only thanks, I'll see if I can work that in

ais523

@ASCII-only right, it's going to be indexed; but although the join is easy to write, there's no point in writing it when you have the question ID

@ETHproductions if you want to filter in a SEDE query, you'll probably want NOT LIKE too btw

@ais523 not if you can't get the question ID directly (i.e. you'll have to get it from the answer ID one way or another)

but... maybe ETH really does have question ID already

ais523

@ASCII-only well, it depends on whether the scenario is "I'm writing a query, which will produce answer IDs and I can join on that", or "I already ran a query and now I want a followup query, how should I identify the rows I want to ask about"
