timotimo that should have a .json at the end 00:02
is your docker container allowed to connect to the internet? 00:03
Itaipu timotimo: yes it can 00:04
timotimo OK, can you try "zef --verbose update" or "zef --debug update"?
hm, doesn't spit out too much more on just verbose 00:05
oh, same for verbose?
or maybe that's just if there are no errors
00:06 robertle_ joined
Itaipu timotimo: paste.scsys.co.uk/585148 (this is the complete error) 00:06
guifa Cool thing I realized with sequences. If you do 1, 2, 3, and you need 1, 2, 3 to collectively produce 3 new digits, you just need to throw it into a slip: 1, 2, 3, {|($^a * 2, $^b * 2, $^c * 2)} 00:08
(I mention only because of the squashathon coming up)
timotimo oh no, it doesn't output any additional info :( 00:09
00:09 robertle left
timotimo Itaipu: does downloading these URLs manually from inside the container work fine? 00:13
i'm not quite sure where to look for the problem here
Itaipu timotimo: hmm... you got it, seems not... so somehow this container can't access network 00:15
timotimo well, docker really enjoys screwing with the network configuration 00:19

guifa What would be the quickest way to turn a space delimited string into a number list? I feel like there has to be something better than $str.words».Int 01:27
timotimo if you want shorter, try +«$str.words 01:28

guifa Damn, that’s a really cool way to do it, unfortunately it ends up causing a consumed sequence error for what I’m doing =\ 01:50
ah well
timotimo aaw
guifa really just wanted to beat perl5 lol 01:51
timotimo it'd be interesting to see where that error occurs; may be enough to "(my@="...")" somewhere 01:52
or a .cache or .list somewhere
guifa (+«*.words).&{(.min+|1,*+2...*>.max-2)∖$_}.keys.join(',') 01:53
I solved it by adding parentheses around the initial bit. I bet it’s a case of being too eager on the right side (because obv there’s no way to know when there’s both right and left directioned stuff) 01:54
timotimo could have been applying the +« to too much 01:55

masak dolmen_: "\n works also like a semicolon" is not quite a correct statement of the rule, IMHO 08:29
dolmen_: it's correct that Perl 5 (and JavaScript and others) work/think a little bit different about this: in those languages, the '}' itself ends the block statement 08:30
so you can easily do something like `if (x == 5) { x++ } console.log("look ma, no semicolon")` in JS. similar in Perl 5.
in Perl 6, the rule is this: you must use a semicolon (`;`) to separate statements. however, if your statement ends with a `}` (because it's a block statement, most likely), then you can skip the `;` 08:32
so, hm, yeah, it's _kinda_ "\n works also like a semicolon", but it only works after a `}`
note... note that Perl 6 doesn't care what the `}` ends. if it closes an object, that works too. 08:33
er, a hash, I mean
m: my $myhash = { foo => 1 }␤say "this works"
camelia this works
masak same if you happen to have an anonymous sub 08:34
m: my $mysub = sub { say "yay" }␤say "this also works"
camelia this also works
masak personally, I think those two are pushing it, by abusing a rule that wasn't meant for that :) 08:35
it looks "wrong" to me not to end a `my ...` statement with a `;`
dolmen_: perhaps the biggest reason for Perl 6 to do it this way -- and this is explained in S04, IIRC -- is so that when people add their own block statements to the base Perl 6 syntax, they behave consistently with the rest of the language 08:37

Ulti ooc there is tonnes of activity on Rakudo but no release since March, is there something special going on? or just no one to release manage at the moment? 09:51
sena_kun I think that 1)the releases are polished better, the ecosystem is checked for compiler regressions and so on, which results in blockers; 2)the release manager is not so eager about making a release every month disregarding possible issues, related to 1 09:53

releasable6 sena_kun, Next release will happen when it's ready. R6 is down. At least 2 blockers. 262 out of 664 commits logged (⚠ 1 warnings)
sena_kun, Details: gist.github.com/5a71beda997299fa86...9915d482d8
sena_kun so anyone who wants to make the release closer can take a look at blockers, I think. :) 09:58
kawaii Ulti: I am the release manager _in training_, being guided by AlexDaniel`, the last two months he has been busy with other things and there hasn't been great need for a release (at least no one is shouting at me for one), in addition to that we're also working on making the release process more polished as sena_kun said, and easier for release managers in general.
There _will_ be a 2019.06, probably in the next week though. 09:59
There are probably questions to be asked like "do we need a monthly release?" too, IMO no, but others may think differently 10:00
a release every 2 - 3 months makes more sense to me at least
and of course you can always use nightly builds from GitHub directly!
tobs is it still a 2019.06 when released next week? 10:02
kawaii if the blockers get resolved in the next 48 hours, we can cut a release branch on GH, pinned to a commit from this month 10:03
so technically?

Ulti kawaii yeah I dont think there is any problem with essentially reducing everything down to Rakudo* like releases and anyone else is just nightly builds at risk... but it might be worth actually *telling* everyone what was just told to me somewhere 10:37
because otherwise unless you look at the GitHub this appears to be a project thats gone to monthly releases to no releases

I've swtiched recently to p6env which I dont think has a nice way to build a bleed version of Rakudo so might have to add that 10:39

Let's give @alexdaniel suggestion a try #2859
 15:26
guifa tobs: other languages that support rationals define the LCM of fractions is defined as LCM of numerators over GCM of the denominators. That’s how J calculates it, for instance. 15:30
tobs aha! 15:32
TimToady feel free to file an issue to fix that (probably for 6.e) 15:33

guifa Which seems like the best choice for the built in (since it’s trivial to take a non-Integer LCM and find the smallest int LCM — just multiple by the denominator, but not so much the reverse) 15:33

Xliff I have this invocation: %classes{$c} := try require ::("Amazon::AWS::EC2::Action::{ $c }"); 16:28
It works when I run it in isolation, however when I try and run it inside a test harness, %classes{$c} is Nil 16:29
If I run it alone, it works fine.
lizmat -I issue ?
Xliff No. -I is fine.
It's the same in the working AND the non-working version 16:30
One sec while I make a checkpoint commit.
This is the problem child: 16:32
github.com/Xliff/p6-Amazon-AWS-EC2...ribute.pm6
If I invoke like this, it works: perl6 -Ilib -e 'use Test; use Amazon::AWS::EC2::Tests::DescribeImageAttribute; use Amazon::AWS::EC2::Tests::TestTemplate; Amazon::AWS::EC2::Tests::DescribeImageAttribute::runTests 16:33
However if I invoke via the test harness, it does not: perl6 -Ilib t/04-actions.t --unit=DescribeImageAttribute
If some adventerous soul could check out that branch and look at the issue, i'd be hugely appreciative. And owe lotsa beer! 16:35
Er. Oh. There's the whole matter of access keys that you would not have access to, but you could still run it and see the crux of the issue. 16:36
Running it without the harness, you get the following from the %classes hash; 16:37
{DescribeImageAttribute => (DescribeImageAttribute), DescribeImageAttributeResponse => (DescribeImageAttributeResponse)}
Running it WITH the harness, the classes hash sets DescribeImageAttribute unexplicably to Nil: {DescribeImageAttribute => Nil, DescribeImageAttributeResponse => (DescribeImageAttributeResponse)} 16:38

TreyHarris vrurg: in your reply to my question as to whether there was a difference between "use v6;" and bare "v6;": I said that I guessed (and tested, which seemed to verify that) the difference would be that "use v6.f;" would bail out until it was run with a version of Perl that doesn't exist yet, whereas a bare "v6.f;" is just a version object in sink context, which might be used by external tools to detect the file 17:38
is Perl 6, but has no semantic use. You responded, "the latest available version is v6.e.PREVIEW though there is not much .e specific yet." I don't quite see what that has to do with my question, could you elaborate?
I used "v6.f" in my example specifically because I thought "v6.e" might create confusion about whether I was asking about a presently-achievable state or not. 17:40
vrurg TreyHarris: then I just misunderstood you. Just ignore the note as irrelevant. 17:43
TreyHarris vrurg: Ah, okay--I wondered if there were actually semantics that I couldn't test without the 6.e preview. Thanks 17:44
vrurg yw
vrurg hopes that got it right time. 17:45

Sometimes my English betrays me. :) 17:46
TreyHarris Incidentally, I hope that in 2025 when v6.z has been released, we name the next releases v6.α, v6.β, etc. Unless the release that comes after v6.f will be v6.10, because we figure there must have been something like ten prereleases before Christmas? :-D 17:48

timotimo also, we won't have yearly language releases necessarily 17:51
17:56 domidumont left
TreyHarris Hmm, how will one pronounce v6̇.a? IPA doesn't give a phonetic meaning to overdot, and the only language I can think of that has a productive overdot is Irish, so "6̇" would be equivalent to "shixh", but x􏿽xCC􏿽x87 doesn't have any meaning... if we assume x􏿽xCC􏿽x87 is equivalent to 'c􏿽xCC􏿽x87s􏿽xCC􏿽x87􏿽xCC􏿽x87', aka "shichsh", then it would sound about like how "shish" in "shish kebab" is pronounced in Turkish... Gives Ubuntu-style naming 17:59
an opening though: Perl Shish, Kebab release
I would absolutetly love to see how many language-detection programs toss their cookies when a language's programs typically has a Unicode combining character in its first few bytes, though. :-D 18:03

Altreus Can I fill in a defined object from a hash? I have objects that have been populated from API requests and not all API endpoints provide the complete object, so there are times when I would like to use a JSON response to fill in properties on an object after construction 18:59
Obviously I can do it manually but that seems boring
sena_kun MOP, but please, do it the boring way. :) 19:00
Altreus Bah! humbug!
can I at least do it in a loop over pairs from the JSON hash? 19:01
Not sure of the syntax in perl6 19:02
self.(.key) = .value for %json.pairs ?
sena_kun 1)you can call a method by arbitrary name; 2)you must document it
give me a second...
Altreus all my objects support the same concept so it's documented as a TODO right now anyway 19:03
sena_kun m: class A { has $.a is rw; }; my $a = A.new; $a."a"() = 5; say $a; 19:04

Altreus can "a" be .key ?
I'm sure there's a way but I never remember it in p6

irced (piping the file into stdin)
(then outputting line by line except each line modified) 22:31
Xliff irced: for .lines.kv -> $k, $v is rw { if $k > 1 { # Make your changes to $v } }
irced (i.e. outputting the modified line)
ok
irced examines the code. 22:32
interesting.. 22:33
ugexe .lines.tail(*-1).map({ ... })
jnthn Probably `$v is copy`, given you want a locally modifiable version 22:34
irced starts coding.
ok, thanks for illustrating two ways Xliff and ugexe! jnthn thanks for the heads up. 22:37
Xliff ugexe: So $?FILE comes out as: "/usr/local/home/cbwood/Projects/p6-Amazon-AWS-EC2/lib/Amazon/AWS/EC2/Tests/DescribeImageAttribute.pm6 (Amazon::AWS::EC2::Tests::DescribeImageAttribute)" 22:38
I want only the DescribeImageAttribute part... 22:39
So...
ugexe yeah, because its precompiled
so use $*PROGRAM
Xliff $?FILE.split('::')[*-1].substr(0, * - 1);
22:39 sena_kun left
Xliff $*PROGRAM contains something wildly different. 22:39
ugexe what does it contain? 22:40
Xliff "t/04-actions.t".IO
ugexe oh right, you are doing this inside a module. and you actually want that namespace piece 22:41
Xliff Yes.
ugexe what are you trying to do with this?
Xliff Unit testing
Modules are loaded from a text file
ugexe i mean with $?FILE and the decomposing of the name
Xliff That is done so I can assign the resulting object to a hash and not have to constantly (try reqire ::(...)) 22:42
This has been a working strategy for at least a week.
Using this method also means that I can use the same code for different objects. Yes, it is mostly cut and paste, but I'd rather than then have to create a new test for every object I am planning on writing. 22:43
ugexe i would not count on the namespace portion of $?FILE showing up as a feature
Xliff Why not? 22:44
ugexe because people should be able to do $?FILE.IO.slurp
Xliff What can I count on? The docs are woefully lacking.
ugexe the only reason it exists is to solve an issue with showing the module name in backtraces for precomped files or something
Xliff ugexe: Yes, I can see that. It isn't the case now. I am looking at what is. 22:45
It's still there. If it's there I am going to use it.
ugexe and this is why we move so slow in the module portion of rakudo :P 22:46
Xliff heh
22:46 Cabanossi left
Xliff However, I think we've veered from the tracks. 22:46
$?FILE is not the issue.
The change in behavior based on the presence of a use statement is. 22:47
ugexe it wouldn't surprise me if that was causing you issues somewhere though
because
Xliff I doubt it.
ugexe it will not always show the module name portion... like when it is not precompiled
Xliff Am open to it, but I've been chasing this thing down all day.
ugexe and if you are trying to load the same module from two difference spots it is possible one will loud from source
Xliff Hmmm...
OK.
ugexe if possible try to not load modules in parallel 22:48
Xliff I am not loading in parallel. At least as far as I think of parallel.
ugexe in zef i finally said fuck it and got rid of lazy loading them to avoid that
Xliff However in my experience, it is not precompilation that's the problem. 22:49
If the use statement on line 5 is uncommented, it doesn't work
If it is commented, it works! 22:50
This throws out the precompilation argument.. I would think?
ugexe well like i said: if a module isnt precompiled its $?FILE wont have a module nam
Xliff But it does, so my guess is that its precompiled. That's irrelevant. 22:51
Listen to what I am saying.
ugexe ...how do you think i got you to find the exact line causing your issue?
Xliff The use statement on line 5 seems to cause lazy loading to throw a Nil when it shouldn't.
Um. You didn't. I did. 22:52
I've been working on this all day.
ugexe i misread what you wrote earlier
Xliff No worries.
And please pardon the terseness. I'm very frustrated at this point. 22:53
And you may very well have a point about $?FILE, but that isn't my primary concern at this time. I will keep my eye on it, though!
brb 22:54
irced ok, here's what I came up with: 22:55
22:55 natrys left
irced my @lines = $*IN.lines(); say @lines[0]; for @lines[1..*-1] -> { print $line; }; 22:55
which prints the first line then joins all subsequent lines into one long line (chopping the newline) 22:56
tobs irced: if you want to join strings, you can also use the &join sub 22:57
m: my @lines = $*IN.lines; say @lines[0], join '', @lines[1..*-1]
camelia »Wann treffen wir drei wieder zusamm?« »Um die siebente Stund‘, am Brückendamm.« »Am Mittelpfeiler.« »Ich lösche die Flamm.« »Ich mit« »Ich komme vom Norden her.« »Und ich vom Süden.« »Und ich v…
irced tobs: i see, thanks! lemme try myself :-) 22:58
tobs ah, that omits the newline after the first line. I tried to make it too short.
22:59 Cabanossi joined
tobs but your previous line is perfectly fine (except that $line should be undeclared in the loop) 23:00
irced tobs: so I have successfuly used your more aesthetically pleasing approach. however, I do not see what you mean about $line being undeclared ?
23:01 epony joined
irced tobs: with reference to my original code that is. 23:01
tobs m: my @lines = $*IN.lines(); say @lines[0]; for @lines[1..*-1] -> { print $line; };
camelia 5===SORRY!5=== Error while compiling <tmp>
Variable '$line' is not declared. Did you mean any of these?
&link
&lines
@lines

at <tmp>:1
------> 3lines[0]; for @lines[1..*-1] -> { print 7⏏5$line; };
tobs irced: ^
irced tobs: oh silly me, i mussn't have typed it! 23:02
tobs: any thoughts on how you might fix your attempt at the one-liner on the second line of your code to interject the needed newline to come after the first line? 23:04
tobs with a second `say` 23:05
m: with $*IN.lines() { say .[0]; say join '', .[1..*] } 23:06
camelia »Wann treffen wir drei wieder zusamm?«
»Um die siebente Stund‘, am Brückendamm.« »Am Mittelpfeiler.« »Ich lösche die Flamm.« »Ich mit« »Ich komme vom Norden her.« »Und ich vom Süden.« »Und ic…
tobs notice the ␤
irced noted!
tobs: silly me semicolon instead of comma was so obvious but yet not at the time to me :-p. nice work condensing it further! 23:07
irced knows but yet is grammatically poor form and is on a role in all languages now. 23:08
irced roll even.
irced asks around if anyone has seen his brain.
tobs I have no idea how memory-friendly join is though. So if you're really just going stdin -> stdout, immediately printing each line as you did in the beginning sounds like a better idea if your input is big. 23:09
irced tobs: hmm, neither do I. how do we look inside the black box? 23:12
tobs: I imagine with the emphasis on concurrency tho that space complexity would be the only concern here (as opposed to runtime complexity). Thanks for the observation! 23:13
