AlexDaniel Hotkeys: polymod? 00:46
Hotkeys: polymod may be cool but…
where is the documentation… 00:47
Hotkeys hiding in the S32 00:48
fairly minimal
timotimo hehe
AlexDaniel ah look, there is an opened issue about that! github.com/perl6/doc/issues/426
Hotkeys oh wow! 00:49
how'd you find that
timotimo he's a magician
Hotkeys :p
I don't think my text explanation is that great
AlexDaniel Hotkeys: that's the only explanation I know of
Hotkeys: I've added a link to S32
00:50 itaipu left
Hotkeys you can link straight to design.perl6.org/S32/Numeric.html#polymod 00:50
I did my best to explain it in my post due to the fact that it wasn't in the docs actually
otherwise I would've just "see docs" probably 00:51
AlexDaniel or right! Thanks
I was looking for that
Hotkeys But I wasn't really sure how to explain it
so i tried and then gave some examples
:p
AlexDaniel Hotkeys: well, another way to do that is to write the docs
and then say “see docs”
Hotkeys Well yes 00:52
but I don't feel like I've explained it well enough, and the explanation in S32 seems a bit terse
AlexDaniel: irclog.perlgeek.de/perl6/2016-02-10#i_12020285 00:53
:p

AlexDaniel uhh 00:54
perhaps we could also have something like “This thing is not documented yet”
and then autogenerate a lot of stuff
00:54 colomon joined
Hotkeys autogenerating signatures and stuff would be nice 00:54
00:55 geraud joined
Hotkeys if possible 00:55
AlexDaniel so that at least the docs say that this thing exists

timotimo okay, so moarvm can now generate heap snapshot dumps in json. i've started on a script that parses its output and generates a bunch of objects. here's my script and example file: t.h8.lv/heap_to_graph.p6 / t.h8.lv/heap_output.json.gz (about 1.1 MB compressed) 02:42

that'd just require the collectables part to wait up for the references part to have reached the required references it references 02:48
or something like that?
or, of course, to give the Collectable object the $from and $to (or $from and $length) attributes and later on referencing them "lazily" 02:49

ufobat is there anything that is done in parallel, unless you explicitly state so? i just know about the hyper operators, is there anything else that might run in parallel? 08:02
i am curently writing a little programm and all my parallel approaches are slower then the sequenzial one.
moritz we don't auto-parallelize anything right now 08:03
just if you ask for it with .race or .hyper
and one reason is that parallelization has quite an overhead on its own, and only makes sense for time consuming operations 08:04
ufobat i guessed its the overhead, yeah :( 08:07
Hotkeys junctions apparently can auto-thread 08:08
but I doubt they do right now
moritz right, they may, but they don't

08:18 zakharyas joined
RabidGravy ufobat, on a first examination that isn't doing more than one thing at one 08:18
you await inside the loop, so it will only start one at a time 08:19
ufobat ah fuck... yes of course 08:20
moritz no wonder it's not faster :-)
08:20 noganex joined 08:21 noganex_ left
moritz what you can do instead: $promise.then( -> $p { say "found the solution with {$_}" for $p.result } 08:21
which returns another promise
and then await for all of those secondary promises outside the loop 08:22
ufobat if i woudnt await them, i guess then the .then wont get executed? 08:23
moritz right
your program might just exit before it ever gets around to executing them
ufobat okay, thanks for the suggestions! i will try them later 08:24
moritz ufobat: please let us know how it went 08:25
AlexDaniel in any case, just don't touch .hyper yet :D 08:27
moritz right, that's horribly broken ATM 08:29

AlexDaniel .race is probably less broken, hmmm. After all of the things I experienced with .hyper I don't have enough hair left to try .race. It would be interesting to know if somebody is using .race for something more or less serious. 08:34

AlexDaniel I'm still wondering why .hyper is sometimes mentioned here as a possibility. With much better luck we could say that things do auto-parallelize right now.

AlexDaniel e.g. on raspberry zero I can dump a few thousands of bytes through SPI from Perl 6. That's not very fast but it's not too slow either. 09:37
Ulti AlexDaniel Raspbian is stable 09:38
AlexDaniel Ulti: like any other debian. Just add unstable repo and install rakudo
Ulti sure but I'd probably want to do that pinned
which is a bit of a pain
tweakism meh, once you've figure out and configured the pinning for that once, it's like riding a bike :) 09:40
Ulti :P
AlexDaniel Package: *␤Pin: release a=unstable␤Pin-Priority: 300
that's it
you wont get updates but hey
that is, you'd have to apt-get install -t unstable rakudo when you want to upgrade it 09:41
tweakism AlexDaniel: I don't know if it's still the case, but I always preferred to aptitude install package/repo rather than -t repo (and I think the same syntax works for apt-get), as the behavior is a little different and you end up w/ fewer packages from unstable that way 09:44
AlexDaniel: (this may be out of date:) -t sets the default distribtion for that command / run of apt, so when dependencies are needed it will look to e.g. unstable first for them 09:45
whereas with packagename/repo it will try to satisfy deps out of whatever you would normally install from byd efault, and only pull them from unstable if it has to
AlexDaniel tweakism: that might be true, I don't know :)
I was sitting on unstable for years 09:46
tweakism although you might prefer the deps from unstable, since that's much more likely to have actually been tested etc. with the pkg from unstable
but I never really had any issues of any significance from pinning. if you mention it in e.g. #debian these days, people throw a fit.
AlexDaniel like, the whole system is on unstable. I've tried mixing the repos some years ago but turns out that it is much better and easier if you just switch completely 09:47
tweakism it depends on whre you are in the release cycle, and moreso, on what sorts of things have changed in unstable
09:47 Vlavv_ joined
tweakism sometimes it's the case that there's a major low-level schism between stable and unstable, and you've get much of anythign from unstable w/o it trying to upgrade all of the base dependencies 09:48
I usually just want some obscure thing w/ few deps, or maybe even a noarch package, though
but yeah, I hear unstable runs pretty well. I got burned once running it on my workstation and now I don't venture past testing, if I would be annoyed by the box being unavailable :)
my apt-get update uninstalled perl or something.. and of course apt is written in perl. 09:49
if that was it, though, nowadays I'd say 'well, obviously your fault for not watching what it's planning to do'
sorry to be off topic, you guys can continue now >:)
moritz but, like, shouldn't apt depend on perl then? :-) 09:50
tweakism moritz: if someting in unstable breaks, it's kindof hard to justify much outrage :) 09:51
**meant earlier: "and you can't get much of anything from unstable…"
AlexDaniel by the way, debian stretch freeze is expected to be on 2017-01-05 or so. This means that stable rakudo (according to debian) will jump from 2014.07 (not even v6.c) to something v6.d-ish. 09:52
which is great
moritz tweakism: right, it's called *un*stable for reason :-)
AlexDaniel

09:54 CQ joined
tweakism heh, actually... I installed my very first ever package from stable-backports today (as far as I can remember, anyway) 09:54
moritz AlexDaniel: TBH I mostly stopped worrying about that. I'm only interested in newer versions of my top 5 or so applications, and I typically find up-to-date install sources from them 09:55
I'm currently annoyed about the old perl version in oldstable, but that's not Debian's fault. It's our fault for not having upgraded to stable everywhere
tweakism moritz: sometimes I wonder what keeps so many people on old-stable (debian itself is pretty trivial to upgrade, but I know people have their propreitary s/w and things they've forgotten how they set it up and stuff), and especially how people *could possibly* stand to be on old-stable 09:57
stable is pretty annoyingly stable already *chuckle* 09:58
AlexDaniel I can tolerate stable packages on servers but on my personal computer I want shiny things :)
moritz tweakism: in our case it's systems that changed "owner" to a different ops team, and they want to recreate them from scratch (and with configuration management) instead of simply upgrading
tweakism: but that takes quite some time, and they are chronically understaffed 09:59
09:59 Vlavv_ left
tweakism I haven't got it finished yet, but my current bootstrap process is pretty much, run a pre-seeded installer on the node, and then there's a (sigh) shell script to get the master up and running; it duplicates the logic for a lot of my states, however it also doesn't really have to do very much at all before salt is up and running and can start configuring the rest of the stuff that way 10:00
it's basically like, set hostname/passwords/enable firewall/install salt from official repo/set some options/start salt/run states
I'm probably forgetting steps 10:01

RabidGravy Say I've got something that is *supposed* to be a CStruct, but accessing the attributes gives rise to a segfault, is there any other way of examining it? 10:01
tweakism RabidGravy: is there any chance that the operation that should have allocated/initialized it failed, and maybe you missed the return/error code indicating that? 10:03
that would account for probably like, 70%+ of that class of error 10:04
10:04 espadrine left
tweakism although... is CStruct a perl thing? if what I said doesn't make sense / apply, ignore me. 10:04
AlexDaniel tweakism: it's not too bad. Once upon a time I opened #python window and confused it with something else. Then a guy asks a question about the difference between ' and ", and so I start my lengthy explanation about interpolation and stuff while the whole channel is looking at me like I am the biggest idiot in the world. 10:05
I'm not even sure if I explained myself. I think that I just ran away 10:06
tweakism LOL
that's pretty awesome
mst AlexDaniel: eh, just say "sorry if that didn't make sense, I should've indented it better@ 10:07
THEN run away
tweakism I mean, not just the ' vs ", but the fundamental difference that perl *has* variable interpolation
10:13 andreoss joined
andreoss is there something like perl5's Test::Simpler to make a output of tests also contain the code which failed? 10:15
tweakism earlier, it was topical in another channel for me to take a pic of myself in a, quote, "funny hat" 10:16
I couldn't find my penguin hat, but I'd like to share the pic with you anyway: i.imgur.com/DhY6tpT.png
... owl's well that ends well.
RabidGravy tweakism, yes a CStruct is a Perl6 representation of a struct, no the allocation isn't faling, and the struct is coming back defined 10:17
tweakism RabidGravy: k, I was afraid of that after I spoke. sorry. 10:18
mst andreoss: probably not yet; Test::Simpler was an insane Damian proof of concept rather than something anybody would actually use, so I suspect the porting priority is going to be the stuff that people use 10:19
RabidGravy *and* if I pretend it isn't a struct but actually a 64bit integer ( its a struct of two 32bit ints) it gives me exactly what I would expect

(or you got something that's not a value from somewhere else... :) )

I mean there's no accessors for this. 12:49
psch jkramer: yes, inside the class you can use the ! twigil, and yes, declared as 'has $!foo' it doesn't get an accessor
12:49 tmch joined
perlpilot jkramer: though, if you have no instance, no storage was allocated for $!a, so you can't get at an attribute 12:50

jkramer I'm confused. $.perl.say just gives me 'MyClass.new' without any content. The instance was created with MyClass.new(foo => $foo). Attribute foo was declared as $!foo but I didn't make a constructor. Does the default new not use $!attributes? 12:53
I mean fill them
timotimo that's correct. private attributes are not part of the API
.new however is part of the API
psch jkramer: correct, private attributes don't get included in the inherited .new and aren't inherited either
jkramer Aaaah that explains everything :) 12:54
12:54 sufrostico joined
timotimo there's a module in the ecosystem that lets you get settable private attributes, though 12:54
from the constructor, i mean
jkramer So I just replace the ! with .? What if I don't want accessors?
psch submethod BUILD
i don't know the details by heart, but afair that's one of the well documented bits 12:55
moritz doc.perl6.org/language/objects#Obje...nstruction
timotimo yeah, BUILD is the way to go if you want to set your private attributes from things supplied in the constructor
jkramer Ah ok. Thanks, I'll try.
moritz jkramer: I'm curious, what's your use case for private attributes that should be settable from the constructor? 12:56
jkramer moritz: I don't know, I just thought it's best practice to make stuff private that you don't want to be accessable from outside the class/instance
timotimo well, accessors are read-only by default already 12:57
moritz jkramer: but setting through the constructor is also a form of access
it's just a write-only access
timotimo "write-once", even
moritz right
timotimo write-once-read-never?
moritz but I struggle to see where that makes sense
I mean, if you allow write once, why not also allow reads? 12:58
you might force your users to do extra bookkeeping if you hide those attributes, with no real benefit
just because somebody said your stuff should be private, yo
jkramer moritz: Well in cases where you need the value to initialize stuff inside the class but there's no reason to make it accessible from the outside. It wouldn't hurt to make it accessable, just thinking it's best practice to hide stuff inside
moritz jkramer: IMHO it's best practise to give the user a good API 12:59
jkramer: hiding things comes second
psch in that case can't you just do what you want to do with the values in .new and safe the result in a public attr..?
moritz psch: right, that's what I'm arguing for 13:00
13:00 sufrostico left
perlpilot maybe it's a simulation where he doesn't want the users to have easy access to the gravitational constant, but rather perform experiments with available methods to discover it ;) 13:00
jkramer But I'm need those attributes in other methods as well. But it doesn't really matter, I guess it doesn't hurt anyone to make the public. 13:05

timotimo you can turn it off?
i imagine there's linter plugins that help, but i didn't know you could straight-up turn it off 13:20
jnthn recently ran across a sizable JavaScript codebase that uses the semicolonless style
timotimo semiconless, eh?
jnthn It was hilarious because it ended up with semicolons in utterly bizare places 13:21
Like
foo()
// blah comment crap
;[a, b].map(...)
andreoss js would be worst example
mst timotimo: things like JSHint will scream about it
jnthn With ; there because otherwise it'd be an array index
timotimo that's ... clever?
mst andreoss: well, honestly, unless you go for -lots- of whitespace sensitivity in ugly ways, it's not going to work 13:22
perlpilot the author apparently liked their own special hoops to jump through rather than the normal hoops
jnthn Funnily enough we'd not have *that* problem in Perl 6 'cus you aren't allowed spaces before your post[circum]fixes :)
mst andreoss: "are you python? no? this isn't going to be pleasant" tends to be how it goes in practice
tweakism I don't think? this is still an issue, but one of the things that I hated most about javascript was it being invalid to have a comma after the last item in a list/sequence 13:23

perlpilot aye, the synbot needs a few more smarts to keep from disappearing 13:36
timotimo do we have any clue who/what is 62.75.169.119 ? 13:37
the journal on hack.p6c.org shows a gigantic amount of "Connection closed by 62.75.169.119 [preauth]"
lizmat euve32551.vserver.de 13:38
stmuk_ German virtual hosting according to whois 13:39
timotimo yeah
i know what whois told me, but i have no clue what person it might belong to
i'm not quite sure what "preauth" means in this case
i don't think it means it was fail2banned. perhaps the script at that address expects a different public key from the server and aborts? 13:40
14.5k matches of that ip and "preauth" in the journal in the last week i think 13:41
mst I think it means that that IP range has been switched to SASL being required due to lack of abuse responses from the hosting company
timotimo can you tell me where i could find that configuration?
huh, it seems related to nagios 13:43
moritz: do we have a nagios monitoring hack.p6c.org? 13:44
because /etc/nagios/nrpe.cfg has allowed_hosts with that IP in there 13:45
we do have the nrpe, the nagios remote plugin executor, running on hack 13:47
moritz timotimo: yes
timotimo so, is the "connection closed in preauth" just a "ping to see if the server is up"? 13:48
moritz no idea 13:49
mst oh, right, that was from sshd, not the bot log
moritz iirc it's bartolin's monitoring server that's checking on hack
stmuk_ its probably just a timeout from sshd for nagios checking that port 13:51
timotimo i expect it's faster than a timeout 13:52
stmuk_ ok a not completed ssh handshake then 13:55

masak rindolf: prefix:<+> has changed meaning from p5 to p6. to the better.
rindolf: in Perl 6, it means "numify" -- "turn into a number"
rindolf: (as it should. the p5 meaning -- "no-op" -- is insane) 18:45
perlpilot masak: except now that bites me sometimes when I try to do it in p5 :)
rindolf masak: ok, this should be in 5to6.
geekosaur yes

masak: and doesn't do the right thing. 18:51
masak well, I don't know what you want to do.

those hashes are even distinct!

masak rindolf: is the above adequate?
rindolf masak: I think so. 18:53
masak \o/
...then if I were you, I'd go with my version :D
perlpilot rindolf: next time, maybe come in with a description like that rather than a Perl5y attempt and we may be able to get you where you want to go quicker :) 18:54
masak was this an XY thing? I'm not good at classifying those?
s/\?$/./
perlpilot I wouldn't quite call it that. More like too much Perl-5-think obscuring the Perl-6-way. 18:55
18:56 CIAvash joined
masak anyway, that sounds like an excellent thing for the (new and improved) #perl6 to help out with 18:56
perlpilot It's too bad something like my @cache[3;5] = {} xx *; doesn't work. That would be sweet. 18:57
"Here's the shape of what I want and what I want in it, now fill it up"

perlpilot masak: why is #perl6 new and improved? 19:11
timotimo because #p6dev was split off 19:12
RabidGravy it was given a bit of a polish
masak perlpilot: what timotimo said.
timotimo now there is even less worry that large discussions and supporting newcomers and such could negatively impact developer productivity
masak it's classic evaporation: because the hot discussions moved elsewhere, #perl6 just got cooler :P 19:13
I'm only a dev because sometimes I can't help myself. at heart I'm a user. 19:14
perlpilot oh good, I thought there might be something I had missed
masak .oO( we didn't say there wasn't ) :P
RabidGravy who was asking about MIDI other than tadzik? 19:15
timotimo i have a side-project brewing (extremely slowly) that also has a tiny bit to do with midi 19:16
but it's not perl6 related
perlpilot masak: perhaps if there's something I'm missing, I just need to aim better. :) 19:17

RabidGravy I've got the portmidi thing reading the stuff okay and just going to start sending in a bit 19:18

ufobat when invoking this perl5ish thingy, isnt the error supposed to be "better"? -e 'my $foo = 12.4; say int($foo)' -> Cannot invoke this object in block <unit> at -e line 1 20:20
moritz ufobat: it used to, before we got the int type :-)
FROGGS azawawi: I got it working insofar that I can open tabs on my blackberry and request a page, locating an input field by name and put some text in it

frozen01 hexdump myfile -> [0a 41 0a]. But after perl6 -pe 's/^\n//' myfile|hexdump -> [0a 41 0a] again. Why??
