integfred Hi, does anyone know if automake, openssl, and the linux kernel is able to build with rakudo perl? 06:38
i'm currently including perl5, but it uses cmd.exe to build using mingw, perhaps perl 6 is different in that it may be able to cross compile somewhat better, assuming it can build the above 06:41

uid9164 <code>perl5 -e "my @a = split(',', 'a,b,c,d'); print @a[0];" <output> a 06:46
<code>perl -e "my @a = split('\s', 'a b c d'); print @a[1];" <output> b 06:49
sorry
<code> perl5 -e "my @a = split('\s', 'a b c d'); print @a[1];" <output> b 06:50
<code> p6 -e "my @b = split('\s', 'a b c d'); say @b[1];" <output> (Any)
How should I write the split pattern to get @b[1] = 'b' in perl6? 06:51
It works in perl6 by typing "my @b = split(' ', 'a b c d'); say @b[1];" 06:53
OK, I just felt confusing. 06:55

discord6 <Aearnus> Yes! It's late here and I might not stick around tonight, but I'll shoot you a follow 09:04
AlexDaniel SmokeMachine: well, being on that list means that you'd have to give your opinion on every such issue 09:05
SmokeMachine: so if you're doing perl6 stuff and want to be involved in that, you qualify :)
kawaii: right, well, I haven't seen anybody doing perl 6 streams yet 09:06
eiro hello people. the download page of rakudo.org is probably outdated and i would like to add the guix package in the 3rd party. any repo for pull requests ?
kawaii I don't think the rakudo.org site is public. 09:07

Geth problem-solving: FCO++ created pull request #82:
Add my name to the list
chloekek eiro: That's a feature if the .so is not an input to the build description of the Perl 6 program in question.
eiro (there was the same on debian package and it's fixed now)
SmokeMachine sorry... I should have clicked on that button... :) 09:14
09:14 Black_Ribbon left
eiro a feature ? how so? my code just doesn't work anymore ... 09:14
kawaii all bugs are features 09:15
eiro (so i have 2 rakudo on my machine: the debian one (outdated) and the guix one (without NativeCall))
chloekek Depending on files being there without them being mentioned in the build script makes the build unreproducible. :)
But if NativeCall doesn't work at all then that's bad. 09:16
eiro kawaii: protecting myself from my own sins... like a big brother
chloekek I maintain a Nix package for Rakudo and NativeCall works just fine, what does the Guix one look like?
eiro well ... i just made guix edit rakudo to see it. i'm waiting for the source 09:17

timotimo damn 12:25
tadzik ugh
timotimo i hope there will be a big shitstorm against google for this
El_Che tadzik's one is still hope 12:26
tadzik how many people can we rally up to make a peertube for this?
El_Che also saw half last night
tadzik because frankly, fuck google
El_Che some ranting about OO :)
timotimo i'm just now watching tadzik's talk about moose
www.youtube.com/watch?v=u12t4PiM7pQ&t=65s
El_Che at 1 am I decided that tadzik would forgive me if I watched the rest today and went to bed :)

in fact I already have! :P

I heard some complaints about the audio, yeah
from what I've heard the provided microphones weren't stellar 12:30
12:32 dolmen left 12:33 pat_js left
timotimo there's some microphone-rubs-against-fabric noise, or maybe it's radio trouble 12:34
timotimo briefly rolls a "takes" syntax for perl6 around in his head
hmm, immootability 12:35
12:37 [Sno] left
chloekek timotimo: What is takes? 12:37
timotimo one point in tadzik's talk is that people tend to abuse "has" to specify arguments to the constructor, even when the things that go there are not actually needed to be stored in the object 12:38
in a later slide he shows a "needs" syntax which is much like what i would have imagined "takes" to do 12:39
but in perl6, that's probably better done with multi submethod BUILD
damn
12:40 pat_js joined
timotimo when tadzik says "i look like this, meet me in the hallway track if you have questions", he's outside the camera's view at that moment 12:40
so how do i know if tadzik looked any different in that moment
like, does tadzik have a physical manifestation for giving talks and one for haunting the hallways?
there's no way to know 12:41
chloekek I think a solution to this would be to better document new, bless, and BUILD. 12:42
12:43 [Sno] joined
chloekek I think the current design is ok but hard to grasp. It's not clear how to write custom constructors. 12:43
timotimo yeah, the difference between "how easy is it to use" and "how easy it is to understand" is surprisingly vast for this 12:44
chloekek Took me a long time to realize BUILD is called on each class in the hierarchy, with the fitting keyword arguments from bless. 12:45
timotimo right 12:49

tadzik needs vs has 13:02
chloekek timotimo: what was this talk called? About needs.
tadzik I don't like publishing slides in general; I feel like if they're useful without the talk itself then I've become a writer, not a speaker and I should've just stayed home
chloekek: How Moose Made me a Bad Programmer, room @, day 1, first talk 13:03
jast well, the published slides might help those who attended the talk recall the key points more easily
I do agree with the general sentiment though
chloekek tadzik: Thanks! 13:04
tadzik good point; fair enough
chloekek never used moose, only bless and hashes
tadzik chloekek: re documenting things better: absolutely. But I'd also like for the better thing to be easier to write in general, even if you know what you want to do :) 13:05
so that you have to fight the tool if you want to do things wrong – not to do things right :)
13:10 lucasb joined
tadzik timotimo: right; Perl 6 has way more resources to do this right, mostly by having really powerful subroutine signatures 13:13
perhaps in our case this is indeed a documentation/education problem :)
timotimo we need a formal docucation 13:14
cygx tadzik: not entirely
you still have to jump through hoops to make Point.new(3,4) work
tadzik cygx: well, you have to do more than with named arguments, yes 13:15
whether that's jumping through hoops? Not sure 13:16
timotimo but really you want special syntax for that: sub infix:<·>($x, $y) { Point.new(:$x, :$y) }
tadzik :>
El_Che lizmat++ 13:17
tadzik but from the top of my head, I'm not sure: should I write `method new(Int $x, Int $y) { self.bless(:$x, :$y) }` or `submethod BUILD(Int $!x, Int $!y) { }` 13:18
I'd rather write the first one because I think I actually got it right
timotimo correct, BUILD doesn't get positional args
tadzik wait, at all? 13:19
timotimo that's right
13:19 AlexDaniel joined
tadzik then I truly don't get it :P 13:19
timotimo positionals don't work well with the "call every BUILD in the object's hierarchy" thing 13:20
tadzik ah right
chloekek Also, kwargs that are not taken by any of the BUILDs are silently ignored, no error.
tadzik but yeah, default .new accepts slurpies anyway
slurpy nameds I mean
13:20 Ven`` joined
timotimo chloekek: there's actually a module in the ecosystem for that! \o/ 13:21
tadzik and when you rewrite it to handle positionals you don't need your own BUILD anymore

timotimo it's a new thing basically
tadzik oh!

timotimo now based on clutter, which has a scene graph
tadzik Clutter, huh
timotimo that file only has a starfield that uses clutter's easing features to scroll a background with depth layers
13:59 [Sno] joined
tadzik I'm not sure what Clutter is. Is it The New Gtk? 14:00
or is the QML of GTK
timotimo slightly, vaguely similar to "the QML of GTK" 14:01
but really a bit more like QSceneView i guess?
QGraphicsScene i think
tadzik nod nod
I'll need to read this :) 14:02
The Gaming JJ suggested a new Perl SDL Game Contest
timotimo oh, cool
tadzik perhaps there should be a perl 6 representation :)
timotimo i didn't see that, was it not in the presentation itself?
maybe i was a little too distracted by @stuff 14:03
tadzik there was a suggestion at the end
timotimo would it be only for SDL1?
Kaiepi tadzik, you could also write it as a subclass of Metamodel::ClassHOW and throw the code for attribute checking in its compose method before calling self.Metamodel::ClassHOW::compose, then throw it in EXPORTHOW::DECLARE::<strict-class> or something if you want it to have its own package declarator or EXPORTHOW::SUPERCEDE::<class> if you want it to override how regular classes work 14:04
since it's entirely dealing with the MOP

Xliff How would you do a conditional enum? 22:13
Say... so that the contents vary due to OS?
sena_kun Xliff, BEGIN { } or sub EXPORT a-a-a-and EnumHOW module. :) 22:14
Xliff LOL! Thought so.
sena_kun ;)
Xliff sena_kun++
I take it you've tried tackling this monster as well?
sena_kun tweaks slides for MOP talk rn 22:15
Xliff, erm, moster to be...?
Xliff Conditional enums... 22:16
sena_kun ah, nope
no usecase for me
Xliff I mean, C just uses an enum definition and constants.
sena_kun but I think it is _very_ doable in Perl 6
Xliff I just canme up with one.
sena_kun I mean, I don't see how it can _not_ work...
Xliff Enum with constants that vary due to OS
sena_kun and if it's not, that'd be a bug
Xliff Think low level IO.
And flags.
sena_kun I think the problem will be how can you use them conditionally 22:17
because afaik they are checked at compile time and must be present
Xliff I want to define them once... at compile time... based on OS.
So it looks like I'll have to create them in MAIN using the MOP. Yes? 22:18
That can get problematic really quickly.
sena_kun so you can't just write, e.g., "if $*OS is Foo { $a = FooParam } else { $a = BarParam }", the compiler won't listen to your "But this branch will never be executed at the place where it is not defined! Ignore it!"
it will say to you that either FooParam or BarParam is an unknown thing. :(
Xliff The problem with that is that it's not just $a. 22:19
sena_kun I think you can workaround that defining every possible enum value, leaving the meaningless ones without a value, say just -1 or something
Xliff Enums have ALL of its values exported to MAIN.
The enum names are the same, though. It's their value that changes.
sena_kun Xliff, why MAIN? `sub EXPORT`(just look it up in the docs) is executed at compile time, MAIN is not
Xliff I may just use Linux as a default and if OS changes, reassign via MOP.
sena_kun ah, if they are the same, just values are different, then you have no such issue. :) 22:20
give me a second...
Xliff I would rather NOT have to use sub EXPORT for just this one thing. In a file where I am exporting a LOT through the normal method.
If I can use EXPORT to help me special case stuff, then fine. 22:21
timotimo did you see that cute EXPORT<bleh> := Bloop::<bleh> trick?
sena_kun Xliff, then BEGIN block somewhere in this method if you have enough data there
Xliff timotimo: No. Where?
timotimo EXPORT::<bleh> i should have said
154915* Kaiepi ? m: use NativeCall; EXPORT::<long> := long; say EXPORT::<long> 22:22
sena_kun github.com/Altai-man/ASN-META/blob...TA.pm6#L75 <- EnumHOW is very neat, Kaiepi++

sena_kun returns to slides, there are 73 of them for 20 minutes

Xliff Thanks, sena_kun++ 22:24
Kaiepi wdym
Xliff Say I have "our enum TheseChangeByOS ( a => 1, b => 2, c => 3, d => 4 ) # Linux"
But the values for a, b, c, and d change for Windows. 22:25
How would I do that in Perl6?
No matter what OS, I still want "a ~~ TheseChangeByOS" to be True
Kaiepi gimme a sec 22:26
Xliff 'k thanks!
