lookatme First one ok
lookatme The code looks awesome 03:32
Herby__ in python, you can have a something be: self.string = None 04:25
what is 'None' in perl 6?
geekosaur Str 04:37
that is, it's a type object
(Any should also work)
Herby__ geekosaur: thanks
i'm looking at some python code that looks like: self._part(name, [], None, clean)
geekosaur m: my Str $a = 'foo'; $a = Str; dd $a 04:38
camelia Str $a = Str
Herby__ so in p6, it might look like: self!part($name, (), Any, $clean) ?
geekosaur generally we prefer the most specific typed undefined applicable
so it depends
(since types help the compiler catch mistakes) 04:39
Herby__ gotcha
geekosaur m: my Str $a = 'foo'; $a = Any; dd $a
camelia Type check failed in assignment to $a; expected Str but got Any (Any)
in block <unit> at <tmp> line 1
geekosaur right, didn;t think it would do that
although in that context (only) Nil also works... but it's not general; for a variable, it means "set to whatever was specified by 'is default' trait, or the type's default if none" 04:40
Herby__ geekosaur: thank you. one more basic question. passing an empty anonymous list as an argument? 04:42
self._part(name, [], None, clean)
geekosaur that .. depends. I'm still a bit confused by promotion and when Array works for List 04:43
Herby__ Do you futz with functional programming much? 04:48
geekosaur uh. I'm one of the maintainers of xmonad
Herby__ I'm a rookie and I have a hard time with writing OO
geekosaur (tiling window manager written in Haskell) 04:49
Herby__ ahh
you familiar at all with python?
geekosaur not very
I can read it, haven't written very much
Herby__ I'd like to convert this (relatively) simple python library to Perl 6. But i stumble with OO
github.com/divijbindlish/parse-tor...N/parse.py
lookatme just like me :)
Herby__ vague question, but could I tackle that with FP? 04:50
FP in perl6
geekosaur honestly? if I'm parsing in perl 6 I'd write a Grammar, rather than doing it manually 04:54
tony-o FP ? 04:55
lookatme Hmm, seems like it is a parser
Functional Programming
tony-o ah 04:56
you could write that parser in a grammar or with fp (i wouldn't write oo for _that_ one in particular) 04:57
lookatme github.com/araraloren/perl6-getopt...arser.t#L6 A simple grammar 04:58
Herby__ I did try my hand at a basic grammar for it: pastebin.com/zmiEnNBE 05:00
ignore the line numbering
lookatme So grammar is OO style ?
Oh, you parse a torrent file ? 05:01
geekosaur it's sort of modified OO, but your 'methods' are perl 6's extended regex syntax 05:01
token, rule, etc.
tony-o grammar is, kind of, a more sophisticated regex
Herby__ grammars seem to have a steep learning curve to do anything useful. for rookies at least 05:02
geekosaur kinda got sucked into a support issue elsewhere, sorry
tony-o and you don't _need_ the actions bit in that file
Herby__ if you're in the mood for solving puzzles, adventOfCode just went live: adventofcode.com/2017/day/1 05:04
gonna use p6 this year
tony-o just finished making pp6 tar work 05:05
can read tar files from git

buggable New CPAN upload: Wikidata-API-0.0.3.tar.gz by JMERELO cpan.metacpan.org/authors/id/J/JM/...0.3.tar.gz 09:23
piojo I just noticed type restraints aren't working when precompiled. Is this known, or should I file a bug? 09:25
m: sub test(--> Array[Pair]) { return my Pair @pairs; }; test
camelia ( no output )
piojo But if you put that in Test.pm6 and run it, with perl6 -I. -MTest -e 'Test::test', it says Type check failed for return value; expected Array[Pair] but got Array[Pair].new() 09:26
I guess being parameterized, this case doesn't get as much testing as the more common types. 09:27
Maybe it only fails for Array[Pair]. Array[Int] works fine. 09:28
teatime is it like Pair([]) 09:33
or something 09:34
piojo1 teatime: when I print the type with .WHAT, the type is Array[Pair] 09:40
And it's the same result if I return Array[Pair].new. 09:41
mscha m: say 'abcdef'.comb.rotate(3); # Do I really need to ... 10:07
camelia No such method 'rotate' for invocant of type 'Seq'
in block <unit> at <tmp> line 1
mscha m: say 'abcdef'.comb.List.rotate(3); # ... spell it out? 10:08
camelia (d e f a b c)
piojo m: 'abcdef'.comb.cache.rotate(3); 10:12
camelia ( no output )
piojo mscha: because Seq is conceptually not list-like. It's more like an iterator. But you can cache the values and treat it as a list after that. 10:13
mscha m: say (1,2,3,4,5) / 2; # this is fine, but ... 10:25
camelia 2.5
mscha m: say (1,2,3,4,5) div 2; # ..; this isn't. A bit inconsistent? 10:26
camelia Cannot resolve caller infix:<div>(List, Int); none of these signatures match:
(Int:D \a, Int:D \b)
(int $a, int $b --> int)

SmokeMachine That totally different error occurred just because I changed the order of the p6x-tag 11:41
DrForr At least that time the line number got in :) 11:44

moritz the error is still the same: :dba(...) makes ~ not work
wander m: say '(abc)' ~~ /:dba('foo') '(' ~ ')' .*/ # seems even break normal matching
camelia Nil
moritz it's just that the default behavior of ~ switched from "throw an exception" to "call FAILGOAL" 12:06

camelia \)

moritz (dba stands for "do business as", and is supposed to set the current rule name for use in error messages) 12:07
wander m: say 'abc' ~~ /:dba('foo') abc/
camelia Nil
wander m: say 'abc' ~~ / abc/
camelia ｢abc｣
wander is this normal? ':dba' is used for error messages, but it looks like even break a trivial matching 12:08
moritz it is not normals. Hence my bug report. 12:09
*normal
wander see.
jnthn I'm not totally sure we ever implemented :dba in Rakudo 12:09
It's certainly in NQP, 'cus we use it for a load of error reporting :) 12:10
moritz jnthn: I'm not sure either, but if it wasn't, at least it was silently ignored instead of f-ing up matches

AlexDaniel Herby_: it depends. The idea behind this particular squashathon this month is about MOLD tickets: fail.rakudo.party/t/MOLD 15:19
Herby_: there are some docs on github.com/rakudo/rakudo/wiki/MOLD...QUASHathon
Herby_ Ah ok 15:20
AlexDaniel Herby_: basically if you find a ticket in that list, and you can still reproduce the issue, than you leave a comment and that's a good enough contribution :)
Herby_: that's probably low-hanging enough
Herby_ sounds doable :)

pmurias AlexDaniel`: why do a Perl 6 golf post? 15:49
[Coke] because it's fun? 15:54
Zoffix pmurias: why do any post? :) Golf post is good. It'll let people glance at readable concice Perl 6 code.
Zoffix ZofBot: concice is conciser 15:55
ZofBot Zoffix, right, but even the error message implies something strange
DrForr And fan the flames over people gleefully pointing out the proof that P6 is even more write-only on the HN article. (not that I truly care about such things...) 15:56
Zoffix DrForr: "even more write-only" than what? 15:58
DrForr 5, natch.
Zoffix DrForr: but it isn't. Why would anyone point it out? 15:59
[Coke] Wy does any troll. 16:00
*why
DrForr Because it gives them something to feel superior and say "See, *my* favorite language is better than *yours*, because reasons."
Zoffix That's no reason to avoid writing an article. 16:00
Otherwise, we'd not write anything. And sit quietly in a corner, afraid to be noticed. 16:01
Time to grow some… whatever bodypart gives you courage… and write stuff :)
Still three spots left. Sign up: github.com/perl6/mu/blob/master/mi...7/schedule
Herby_ Zoffix: ++ on the advent article
matthias__ Hi everyone. How can I type a constant? As in give it a type.
Zoffix matthias__: it's a constant. It doesn't need a type 16:02
DrForr Didn't say it was, pmurias was asking rhetorically "why..."
Zoffix DrForr: you mentioned flame fanning. That sounded like critique against writing to me :) 16:03
DrForr Coming from someone who's just written a blog post and is writing an advent post over the weekend :) 16:04
It would be hypocritical of me to advocate against writing and then go on writing :)
comborico1611 Matthias__ variables are constant by default in perky, i think. I'm new.
Perl6
jnthn m: my Int constant c = 42 16:05
camelia ( no output )
jnthn Our `our` depending on the desired scope
DrForr Some days I tire of this and think I missed my true calling as a watchmaker, don't know why.

comborico1611 Zoffix, 3 spots left to create Advent puzzle? 16:06
matthias__ Zoffix: jnthn: I see, thanks.
Zoffix comborico1611: three empty spots to sign up to write Advent blog posts. 16:07
comborico1611 I see. I'm not qualified.
Zoffix There're 24 posts altogether; one per day, so number of spots is limited
comborico1611: why not?
comborico1611: have you used Perl 6 at all?
comborico1611 I'm floating all over the place with programming languages.
Zoffix :)
DrForr comborico1611: No less qualified than anyone writing, that's impostor syndrome talking :) 16:07
comborico1611 All I've done is red three quarters of a book. 16:08
DrForr comborico1611: All the more reason, you have a perspective most of us don't :)
comborico1611 True.
perlpilot comborico1611: what DrForr said. Share your experience
comborico1611 Haha. You guys are funny.
DrForr Which book, BTW?
comborico1611 Think Perl6
perlpilot comborico1611: alternatively, you could give a kind of book review :) 16:09
matthias__ jnthn: So whenever I explicitly add a type I have to explicitly set `my` or `our`? Is there reason for constants not defaulting to `our` in that case as well?
DrForr Ah cool, I need to pick up my copy; probably at FOSDEM and see about getting it signed :)
comborico1611 Hmm. I do have a book review in-the-works for this book.
Nice.
comborico1611 I want to hear jnth say a book review would be fine for Advent post. 16:10
Zoffix comborico1611: see my last eval above; jnthn's way isn't working. It's constant without a container and with a mandatory. It doesn't need a type. How come you're trying to set the type?
comborico1611 Then i will do it. :-)
Zoffix A book review is fine for Advent post. 16:11
*mandatory value
jnthn matthias__: The declarator is required so we know to parse a type next. That's just the way the syntax works; it's consistent with every other declarator in the language.
comborico1611 Alright.
perlpilot comborico1611: it's weird that you would single one jnthn as the arbiter of what's good for an advent post.
comborico1611 I'm not trying to set a type const. I was just trying to answer matthias's question.
DrForr No need to ask permission, just add yourself to the list :) 16:12
Zoffix comborico1611: oh, right, too many people. Wrong person :)
perlpilot s/single one/single out/ # I swear, my brain is weird
comborico1611 Perlpilot, yeah, sorry no offense. I just don't know who's in charge here. And I don't want to commit myself to that post and look like an idiot if that content isn't suitable for Advent.
Zoffix No one's in charge. Anarchy \o/
comborico1611 I doubt that. 16:13
I will sign.
scimon So.... I love perl6's operator chaining. Is there a good explanation anywhere of how it works though?
m: say [(^)] ( (1,2,3,4), (5, 8, 9), (2,3,4,5), (5,8,9) ).pick(4)
camelia set(1)
perlpilot comborico1611: okay ... I'll claim to be "in charge" since colomon and I first setup the Perl 6 advent calendar all those years ago. And since I'm in charge. Write something! We'll help if you need it. 16:14
scimon The fact that always returns 1 is frankly mindblowing.
perlpilot :-)
comborico1611 How to I sign up?
Haha. That's funny that you happen to be the guy that set it up.

Zoffix scimon: that one just introspects the op you're using to figure out which one of META_BLAH_BLAH routines to call under the hood. For the `(^)` op, it calls these: github.com/rakudo/rakudo/blob/mast...#L401-L415
comborico1611 But my goal in this review is to express when I truly feel the best way to learn to program is. Because his book is set up as an introductory course to programming.
scimon Right I'll now not think about it until Monday (Party tonight... recovery this weekend)
comborico1611 When equals what*
scimon Zoffix: but it's more how it manages to handle things like 1 < 5 < 10 16:23
The number of languages that can parse and manage to give a sane answer for that are minimal.
I mean in the example I gave 16:24
Zoffix m: sub infix:<z> is assoc<chain> { dd @_ }; 1 z 5 z 10
camelia [5, 10]

camelia set(1)
scimon In most languages that could do the set stuff you'd end up doing (1) (^) (5,8,9) and get (1,5,8,9) 16:25
Zoffix Though for `<` op, there's additional chainage with other ops. That's currently not available in userland for custom ops and is done by the compiler.
scimon Like I say... it's stunning and something we should be talking about more.
(I'll be mentioning it in my Advent page)

Ulti I was mostly going to cover Tux's stuff my BioInfo tests, the Prime number benchmark which was posted ages ago and then show just how many commits there have been around perf since "Christmas"
maybe highlight major work thats been done and point at it like improved JIT/spesh stuff and the improved concurrnecy support 17:33
wander 01:30 am here, today i'm too tired for lab things, good night #perl6 _zZ
&
Ulti one of the original prime number benchmarks uses grep so I can chuck a .race on it 17:33
AlexDaniel wander++ 17:34
timotimo is race good enough, or should it be hyper?
(i'm also wondering if the csv test shouldn't also be hyper instead of race. though maybe it actually is)
Ulti can do both and talk about the difference
but yeah if there's anything you want to add I'll try and get it done ahead of time so people can check it out 17:35

El_Che HN thread is somewhat depressing but there is a point there. 17:45
I am also under the impression that we tend to show of the expectacular-and-cute-but-not-that-useful bits of the language instead of the ton of good stuff (tons) 17:46
El_Che no critic towards the post itself (or the upcoming one), but it feels kind of cultural 17:47
Ulti oh man no one put up the latest post on HN surely 17:56
show casing powerful stuff no one should ever do... thats anti martketing 17:57
Ulti its a cool, fun, intersting post but someone reading it from a thousand miles up on some enterprise Java high is going to just be afraid 17:57
every single one of those comments is exactly what Id expect, especially given most people will have only ever seen a couple of examples of an P6 in their life :9 17:58
El_Che Well, it depends on your public. Most people (imho) will get or see the fun in the "cool" stuff once they get the more mundaine stuff. So it can be a very in-circle thing 18:01
robertle also having scissors is nice, but you need the discipline not to run with them... 18:02
El_Che robertle: the problem is not that you can do weird/advanced stuff with the language (that's a plus), but people from the outside with only look at the golfing and/or urf8 cuteness and not look further 18:08
AlexDaniel looking at my rough notes, there's nothing scary in the upcoming golf post. Shit might hit the fan when I show stuff encoded in base 0x10FFFF, but other than that it's cool and readable. 18:09
(ha, talk about utf8 cuteness)
El_Che - "Oh, we need a new name. Sharing the name with Perl 5 is confusing and we get bad press from matt's archive in the '90" 18:10
- "Oh, let's golf"
:)
AlexDaniel: looking fwd to your post, but I am probably inside the bubble already :) 18:11
I don't know if a make any sense. I don't want to sound like I'm trolling
AlexDaniel El_Che: it makes sense, but it's irrelevant I think. There's a type of people who will find something to shitcomment about anyway, and it doesn't matter if we give them a reason or not. 18:13
El_Che actually, I am not talking about HN in particular
I couldn't care less about that 18:14
El_Che and even that is better than being ignore in a way, it may be a sign of modest succes 18:14
Ulti AlexDaniel: yeah on the code golf challenge site with P6 I set myself the challenging of keeping it readable and small, I came second or third on a couple 18:16
El_Che I point out that on one way Perl 6 wants to differenciate itself from perl 5, and on the other hand it repeats the kind of compressed smartness and cuteness that gave perl5 a bad reputation 18:17
El_Che in that send, we're sending mixed signals 18:17
Ulti yeah I really agree with that
and for the most part the advent calendar has done a reasonable job of not going too nuts
El_Che s/send/sense/ 18:18
Ulti I like the post though, so haters are going to hate... if you cant pick up its an article about antipatterns/footguns which are cool but obviously evil and wrong you probably shouldn't program in Perl 6
El_Che Ulti: I agree. But if loud enough they can influence people to not even try the tech 18:20
(ask perl 5)
Ulti yup
I would perhaps not have put the day 1 post as what not to do :D
Ulti but its fun and well written which youd hope would trump that 18:21
for some reason half of hacker news have absolutely no concept of "fun" with respect to programming, let alone a sense of humour
El_Che it's only a few fun posts and not a manifesto. Nothing is lost. I am only concerned about the mixed signals.
Ulti meh Perl 6 should embrace living amongst the mixed signals 18:22
teatime remembers that time someone's (Zoffix's?) talk slides covering unicode operators + defining the shrug-emoji-string as an operator, and [reddit or HN comments, can't remember which] assumed it was a joke for the longest time.
El_Che Ulti: there are a lot of angry people on the net, but that's not new :)
teatime then kinda totally missed the distinction between 'this is cool' and 'you should really do this' heh 18:22
El_Che hehe 18:23
Ulti yeah :/ I regret this 2012 post blog.mattoates.co.uk/2012/02/perl6-...ators.html 18:24
El_Che I am one of those people that regularly work on 3 OS'es and there is no way I'm learning to remap keys on all 3 and memorize the differences :P 18:26
I'll always be a texas ranger that way ;)
Ulti Im kind of tempted to make a Test::Random that has that pile of poo operator 18:27
teatime El_Che: I have always been a big Compose key fan; WinCompose is OK on Windows, and of course it's fine on *nix¹... I do not know of a way to get it on OS X, though (I don't use Mac, but I wish I knew of where to point Mac users for Compose functionality, if it can be done.)
¹Until GNOME/GTK decided to do their own thing and break it for possibly no good reason. Surprise? 18:28
El_Che I am utterly disappointed on keyboard shortcuts o a mac
of
Ulti if you see a pile of poo you just get a fuzzer on something
teatime bbl
El_Che Ulti: you would pretty far to prove my point, he? 18:29
Ulti El_Che: ctrl+cmd+space on a Mac FTW
El_Che looks like IOS 18:30
and workflow-breaking
Ulti it jumps the focus to the search and you can press enter so its not too bad 18:31
oh it doesn't... I swear it used to highlight if you managed to get down to a single emojii 18:32
AlexDaniel perhaps the squashathon is more interesting than discussing piles of poo? :P github.com/rakudo/rakudo/wiki/Mont...Squash-Day 18:42

clarkema Hi all. I'm playing around with the Advent of Code as a source of little puzzles for learning Perl 6 (adventofcode.com/2017/day/1) I have a working solution for today's two challenges, but I'd love some feedback on style and idiom. My solution is at gist.github.com/clarkema/d0b6d8d95...474861db2a -- in particular, it feels like there should be a better way to get an array of digits out of the string. 20:54
Any pointers very gratefully received!
masak m: .say for "65536".comb
camelia 6
5
5
3
6
clarkema ah, thanks! 20:55
masak :)
in general, `.comb` is the opposite/dual of `.split`
`.comb` is for when you want to keep things. its default is per-character 20:56
clarkema that's really handy, thanks! It looks a lot less ugly 20:57
clarkema so you're specifying what you want, rather than what you don't, and you don't get the extra two empty matches at each end 21:01
AlexDaniel m: my @d = ‘911229’.comb; @d .= push: @d.head; say sum gather for @d.rotor(2 => -1) { take .head if [==] $_ }
camelia 12
AlexDaniel rotor, gather/take, […] :) All in one snippet 21:02
clarkema *reading up on rotor* 21:04
AlexDaniel m: say ‘12345’.comb.rotor(2 => -1) 21:05
camelia ((1 2) (2 3) (3 4) (4 5))
clarkema That's pretty cool - I originally started off wondering if I could extract pairs like that but couldn't find an easy way to do it; so it's nice to see a solution for that approach
clarkema (although as a spoiler the next part of the challenge involves testing against the digit half way around the array, instead of the neighbough, so I ended up rotating on (@digits.chars/2) 21:06
What's going on with the 'push:'? it obviously expands to something like @d = @d.push(@d.head), but I havn't seen an explanation of the colon approach 21:11
teatime `push: a;` is equiv to `push(a)` 21:12
docs.perl6.org/language/syntax#Precedence_Drop 21:13
clarkema Interesting, thanks -- didn't really know what to search for that one. Definitely looks like something to beware of on longer chained calls 21:15
AlexDaniel Is that the reduction metaoperator in the take clause (as in, you're reducing a two-element list from the block argument to a boolean) or is something else happening? 21:22
Zoffix AlexDaniel: yeah, fail.rakudo.party updates every 10m via a cron job 21:29
perlpilot clarkema++ thanks for reminding me about adventofcode.com :) 21:30
AlexDaniel clarkema: yeah, it puts == between the elements of the list 21:36
clarkema: so it's pretty much identical to .[0] == .[1]
(given that you only have two values)
clarkema Great -- I had the feeling my grep option was a little verbose
perlpilot: It's really handy to have some little challenges like that to provoke questions when learning something new! 21:37
perlpilot clarkema: yeah. It's also great just to play :-) I found out about it last year in the middle of advent and started writing some Perl 6 solutions, but I got side-tracked and didn't do them all. I'm going to try to do them all this year. We'll see how it goes 21:39
afresh1 is solving it in perl6 - github.com/afresh1/adventofcode 21:41
perlpilot afresh1: cool
afresh1 but I'm terrible at perl6, so looking forward to seeing what other folks here say 21:43
perlpilot Looks like all of the Perl 6 Advent slots are filled (yay #perl6 people!) but I bet some of the adventofcode.com solutions would be worthy of a future Perl 6 Advent post
the adventofcode problems kinda remind me a little bit of MJD's Quiz of the Week 21:45
clarkema afresh1: some interesting stuff in your solution as well; TI certainly MTOWTDI
afresh1 going to go try to actually understand `comb` and `rotor` now though :-) 21:46
clarkema it's nice to see your :skip-empty as well though

camelia Instant:1512164069
Error while reading '/home/camelia/p6eval-token': No such file or directory at /home/camelia/rakudo-j-inst/bin/eval-client.pl line 10.
perlpilot baest: yeah, someone mentioned that yesterday I think and I was guessing leapseconds, but there's only been 26 of those. 21:50
in any case, it seems very familiar to me though I don't know the reason why 21:51
teatime GMT time is off 18 seconds from UTC
but that doesn't help
baest perlpilot: :)
teatime TAI is off from UTC by at least 34.1 seconds 21:52
perhaps more, dunno how old my reference is
perlpilot confluence.qps.nl/display/KBE/UTC+...Correction 21:54
See the first paragraph
teatime en.wikipedia.org/wiki/International_Atomic_Time
it's TAI, 37 seconds from UTC
mmm
perlpilot so it is leap seconds plus the initial difference of 10 seconds 21:55
baest Wow ok, that explains it I guess, but still not very useful that you can't create a DateTime with an Instant from another DateTime and expect them to be the same time 21:58
perlpilot Why are you converting your DateTime to Instant anyway? 21:59
teatime Instant is by def. TAI 22:01
whereas DateTime's are in UTC or zones offset from UTC
but, they should round-trip...
masak .oO( this isomorphism is bent! ) 22:02
baest perlpilot: storing them in a database as an int 22:07
perlpilot baest: why not store them as a string in ISO8601 format? 22:08
teatime it may not be different, at least for you / at the moment, but perhaps .posix would be more appropriate
or, yeah, even better that
baest more storage with a string and I like being able to manipulate easier through SQL. Should probably use PostgreSQL and store them as a timestamp 22:10
perlpilot pg groks ISO8601 too 22:11
and I'll point out that concern over storage space is what caused all the Y2K hoopla 22:12
baest still with SQLite as I use currently you will not be able to manipulate them easily. But the important thing for me is to know what caused the thing 22:15
baest Thanks for the help guys! 22:22

kupopo I'm getting a cryptic error when trying to `make install` rakudo-star-2017.10: ./perl6-j tools/build/install-core-dist.pl $PREFIX/share/perl6 fails with Unhandled exception: VMArray representation does not implement bind_pos_native. Has anyone seen or heard of this? (Google didn't turn up anything useful) 23:46
lizmat kupopo: could you add --ll-exception after ./perl6-j and gist the output ? 23:48
kupopo: otoh, I'm not sure of the state of the JVM backend even allowing a "make install" at this time 23:49
kupopo lizmat: here's the full stack with --ll-exception: gist.github.com/shicks/27df7cf0d86...50942d4c62 23:52
I'm a bit confused about that - my understanding is that the JVM backend is basically usable, no? Is it not meant to be installed? 23:53
lizmat bartolin would really be the person to answer this question, as he's been the one working on the JVM backend lately 23:55
personally, I have focused all of my efforts on making things faster on the MoarVM backend
.ask bartolin is gist.github.com/shicks/27df7cf0d86...50942d4c62 something you'd expect from a "make install" ? 23:56
yoleaux lizmat: I'll pass your message to bartolin.
lizmat kupopo: but from the error message, it would seem to me there's something not implemented on the JVM backend that is being used in the install process
and/or not properly worked around on the JVM backend 23:57
lizmat :-( 23:57
lizmat hopes bartolin can share some insights
kupopo Thanks. I guess I'll ask my more general "what are you actually trying to do?" question - I'd like to share a perl6 program with folks who don't have perl6 installed. I'd hoped to try using a jar file for this (and maybe that wouldn't work anyway), but maybe there's a better supported solution? 23:58
(i.e. perl6 is not standard in any linux distributions I'm aware of, unlike perl5 which one can generally assume exists) 23:59
