lizmat that's because the native gets upgraded before any method can be called on it
ZoffixWin hm 00:01
lizmat if you want to use nqp:: ops, you need natives 00:02

ZoffixWin native types are a total mess. I keep finding new bugs :S 01:02
ZoffixWin is still working on that promised ticket
Juerd ZoffixWin: One of the underlying issues might be that they're not implemented as the respective native types. 01:03
ZoffixWin There's a lot of inconsistency too: 01:04
m: my uint8 $x = 0; $x--; say $x
camelia rakudo-moar 780192: OUTPUT«-1␤»
ZoffixWin m: my uint8 $x = 0; $x-=1; say $x
camelia rakudo-moar 780192: OUTPUT«255␤»
Juerd m: my uint8 $x = 255; $x++; say $x
camelia rakudo-moar 780192: OUTPUT«256␤»
Juerd +=1 works fine
++ borks
ZoffixWin m: my uint8 $x = 256; $x++; say $x
camelia rakudo-moar 780192: OUTPUT«1␤»
ZoffixWin m: my uint8 $x = 256; $x+=1; say $x
camelia rakudo-moar 780192: OUTPUT«1␤»
Juerd But the way in which -- and ++ bork is interesting: they result in values that a native uint8 *cannot* hold.
ZoffixWin m: my uint8 $x = 255; $x+=1; say $x
camelia rakudo-moar 780192: OUTPUT«0␤»
ZoffixWin No, ++ works fine, +1 borks 01:05
It has an extra bit
Juerd This gives away that apparently it's not really a native, but instead something that's made to look like one
01:04 <+camelia> rakudo-moar 780192: OUTPUT«256␤»
ZoffixWin m: say 0xFF
camelia rakudo-moar 780192: OUTPUT«255␤»
ZoffixWin oh
never mind me 01:06
Juerd A maxint is always odd :)
ZoffixWin m: my uint8 $x = 255; $x++; $x++; say $x
camelia rakudo-moar 780192: OUTPUT«257␤»
ZoffixWin heh
01:07 vendethiel left
Juerd It looks like whatever wrapper's around assignment or +=, is missing in ++ 01:07
sena_kun Any pretty one-liner to bind a key-value from anarray to two vars? Like '($key, $value) = @array-of-pairs[0]'. And general way to do this thing(unpacking data structure at '=') will be great. 01:08
s/anarrray/an array/ 01:09
Juerd sena_kun: $pair.kv probably does what you want :)
ZoffixWin sena_kun, what's "an array of pairs"?
m: my @a = (foo => 'bar'),; my ( $key, $value ) = @a[0]; say $key, $value
camelia rakudo-moar 780192: OUTPUT«foo => bar(Any)␤»
sena_kun Juerd, thanks.
ZoffixWin That works
Oh no
Juerd m: my @foo = :1pair, :2pair; my ($k, $v) = @foo[0].kv; say "k=$k, v=$v" 01:10
camelia rakudo-moar 780192: OUTPUT«k=pair, v=1␤»
ZoffixWin aha
Well.... I'm bored with this. 01:11

sortiz Juerd, ZoffixWin, Seems that the problem with ++ and -- vs native is that those operators are implemented by .succ and .pred, that as methods upgrade the native to Int loosing all size info.

Juerd Hmm
Precedence games are hard. Hurrah for simple expressions.
TimToady . is tighter than +
Juerd I'll stick to just using : only once per expression :) 01:35
Juerd really likes the : for method calls 01:36
That is, with .
leont It combines well with whateber expressions, and blocks in general 01:38
Juerd TimToady: Not specifically referring to indirect object notation, but more a general question: is it likely that features are removed from the language in 6.d, if it turns out that almost nobody appears to use them?
TimToady that depends on whether I use them :)
Juerd Fair enough :) 01:39
leont: I just don't like having lots of parens and brackets 01:40
: is a great way to remove one layer without sacrificing clarity 01:41
And although I forgot why : was needed for method calls, but not for function calls, I got used to it much faster than I expected 01:42
TimToady foo.bar is assumed to not take arguments because it's often just an attribute 01:43
Juerd Ah :)

leont I hit the same issue before, I don't think there is 01:48
Juerd Hm, did something during runtime get much faster recently? I have this thing that "feels" faster.
awwaiid I asked before and I think it was "no", but thought I'd triple check :)
Juerd awwaiid: If you want that, don't you actually want an array instead of arguments? 01:49
01:49 sena_kun left, kaare_ joined
awwaiid Juerd: yes... but I want to call it without explicitly passing an array. This is for calling a proxy to a ruby method, and the ideal would be to get one list of args like this 01:51
Juerd You'll need some kind of wrapping 01:53
An array, a capture (\:fish), your own pair-creating operator... 01:54

02:11 xpen joined
awwaiid for some reason I thought you could map: { ... }.map: { ... }, but I guess not 02:11
makes more sense that you can't
Juerd If you use the loose . you'll have to use () around your arguments to keep things in line with what you'd expect. 02:12
ZoffixWin I kinda wish there was SOME method to continue the chain, without having to go BACK and change to ()
like .map: {} :.map: {}
Juerd Ew 02:13
ZoffixWin :(
Juerd I use : for impure methods mostly
And I don't like chaining those (I'm against returning self for the sake of chaining)

TimToady ceiling by definition coerces to Integer; why would you expect it to stay FatRat? 03:27
Int I mean

TimToady so he did...
Juerd Ask a question on irc, leave. That's a common pattern that I still don't understand. 03:28
sammers what is the best way to pass the version number (my $gd_version = v1) to the native trait? When I try to use it like this `native('gd', $gd_version)` I keep getting this warning: Use of uninitialized value $apiversion of type Any in string context. I have tried w / wo quotes, using Version... 03:30
Juerd I don't understand why the error message says $apiversion if you used $gd_version. 03:33
skids Try an --ll-exception? 03:34
grondilu it would make sense for FatRat.ceiling to return a FatRat. For the same reason that $someInt.FatRat / $someDivisor does not return an Int.
Juerd Other than that, I'd expect 'my $the-variable = BEGIN v1' to fix it :)
grondilu m: say (3.FatRat / 3).WHAT
camelia rakudo-moar 780192: OUTPUT«(FatRat)␤»
grondilu but that may be me whining again about the Numeric model :P 03:35
Juerd grondilu: .ceiling exists to return integers, whereas / just happens to return them under the right circumstances.
03:37 noganex joined
sammers Juerd, $apiversion is from NativeCall guess_library_name 03:37
skids Well, C's ceil/floor/trunc/round stays the same type, FWIW, to get an int you need to use rint. 03:38
Juerd skids: C's strings don't do graphemes
So not really worth much, imo :)
sammers Juerd, ok, I just tested `my $gd_version = BEGIN v3;`, but am seeing the same warning. 03:39

Juerd sammers: I can't seem to reproduce it anyway... 03:39

09:40 wamba joined
moritz if yes, and all the requirements are installed, please submit a bug report 09:40
'cause we can only fix the bugs that are reported to us 09:41
(and just for the record: until 5 years ago or so it was a pain to buid perl 5 SSL modules as well, and at that time, the perl 5 ecosystem was well matured)
geekosaur haskell, with a more mature ecosystem, still has problems with SSL 09:42
basically bootstrapping https support is insanely painful 09:43
and becoming more so, because you generally have to download extra stuff to do it... over SSL 09:44
and the base SSL support (openssl, gnutls, whatever) is large and complex enough that you really do not want to bundle it --- plus, since it's not "owned" by the language ecosystem, it then becomes harder to upgrade in case a security fix is released 09:45

09:59 raiph left
funrep abraxxa: alright 10:00
brachtmax thanks - and yes I agree...I just wanted to understand the syntax - I'am teaching a perl5 class where I'am
funrep RabidGravy* sorry
abraxxa funrep: hm?
brachtmax saying a few words about perl6 and I got asked this question
geekosaur brachtmax, there's a few things going on there, some surprising until you understand why 10:01
first off: `my Array[Int] $x` means that $x is a single item to which you can assign an array of Int
gfldex .seen hankache 10:02
yoleaux I saw hankache 27 Jan 2016 10:14Z in #perl6: <hankache> i got to run. FROGGS++ for the release
brachtmax oh ahh..that explains the error I got - thanks!! 10:03
geekosaur second is the surprising one: when you say $x[0], perl6 silently "corrects" that to $x. because that same "correction" lets you use lists and scalars interchangeably in the same way perl 5 did, instead of forcing you to coerce all the time
gfldex .tell hankache could you add (basic) typed arrays to the intro please?
yoleaux gfldex: I'll pass your message to hankache.
geekosaur (basically, if you use an array operation on a scalar, it pretends the scalar is a 1-element array)
Juerd geekosaur: s/array/list/? 10:04
geekosaur yeh
Juerd Or rather, a positional operation ... 1-element list?
geekosaur should not be awake rigt now, brain is about half asleep and half bundle of anxiety :/
yeh, I'm also trying to not be too pedantic 10:05
Juerd You can have the functional halve of my brain
I'm sick so I should be sleeping anyway
geekosaur perl5 monks like to haul in the deep pedanticism right off and it just scares people away (this IMO is a large part of why many people don't like perl(5) any more)
Juerd I'm not trying to be pedantic, I'm trying to get more details from you to understand the issue better myself 10:06
geekosaur I am trying to recall details, but I think it is in Any where it implements various Positional role methods by pretending a scalar value is a 1-element collection that does Positional 10:10
and this makes a number of things work "as expected" but also results in this cute little edge case 10:11
moritz every DWIM comes with a WAT
geekosaur ^
10:11 domidumont joined
RabidGravy I think this in relation to the failing example shows it 10:12

camelia rakudo-moar 780192: OUTPUT«[1 2]␤»
geekosaur right, that's the first part of my explanation
moritz why do folks use $ for array variables?
RabidGravy dunno
geekosaur because it works for some things 10:13
Juerd moritz: I've seen two Perl beginners do this recently; they're just not used to @ and %.
RabidGravy I think it's because of the P5 ArrayRef thing

RabidGravy :) Glad it works for you 10:53
perlawhirl I was playing with it today and made a sort-of 'ls' using it: hastebin.com/isinubehin.pl' 10:54
RabidGravy I'd been meaning to make it for ages but never had sufficient impetus which you provided
perlawhirl glad i could help 10:56
RabidGravy I thought I had made a Str method 10:57
perlawhirl for the perms? 10:58
RabidGravy yeas but no I didn't - false memory
perlawhirl well feel free to steal mine. i'm not sure if there's a more efficient way. i had that buried in an old perl5 script... i don't recall where i got it from 10:59
10:59 lnrdo joined
RabidGravy well, there's definitely a more generic way as all the bit shifting and masking is done 11:00
perlawhirl i tried making it more six-y. zipping the mode in binary with <r w x> ** 3, then doing something like : state $string ~= $b +& 1 ?? $s !! '-' 11:02
but it was slower than the bit-shifting
RabidGravy the .user .group and .other methods return an Int with the Permissions role
which gives it the .execute, .read and .write attributes 11:03
perlawhirl ah
11:03 lnrdo left
perlawhirl i might play around with it some more. not that this ls script serves any purpose :D 11:03
11:06 cognominal joined
RabidGravy similarly file type and setuid, setuid, sticky and so forth all have accessors 11:07
on the main mode object
perlawhirl yes i did see those
but yeah, i had this bit-shifty thing in and old perl5 script, so i just copy/pasted, translated a few operaters and dusted my hands 11:08
RabidGravy I think the reason I didn't do Str was that I was in the middle of doing something else at the time 11:10
perlawhirl all good. i don't have a need for it outside of re-implementing ls, but feel free to add it 11:11

fireartist oh! 11:15
RabidGravy the accessor is a rw method with no arguments
fireartist I don't know why I'm finding this so difficult! :-) 11:16
ab6tract i have encountered a strange interaction between react and Proc::Async
react { whenever "/tmp".IO.watch -> $c { my $cmd = Proc::Async.new('echo','foobles'); await $cmd.start } }
RabidGravy almost literally "method x() is rw ( $!x }"

11:16 travis-ci left
ab6tract the await on a Proc::Async will break out of the react loop 11:17
*most* of the time
RabidGravy you want it do that? 11:18
11:18 kaare_ joined, espadrine_ is now known as espadrine
RabidGravy react { whenever "/tmp".IO.watch -> $c { my $cmd = Proc::Async.new('echo','foobles'); whenever $cmd.start { done } } } ; # or something 11:18
ab6tract RabidGravy: nope, i want it to keep reacting until i call done 11:19
RabidGravy then omit the done there
ab6tract i don't have a done in my example, but the react block still finishes
if you touch multiple files, you will only get one 'foobles; 11:20
*'foobles'
or two if you are really lucky 11:21
RabidGravy react { whenever "/tmp".IO.watch -> $c { my $cmd = Proc::Async.new("echo","foobles"); whenever $cmd.start { say $c } } } 11:23
appears to work *forever* for me
ab6tract so the answer is: don't use await inside of react blocks? 11:24
but the problem is that then you cannot call a subroutine which does normal await-y things
could also be an
OS X issues :/
RabidGravy well the inner whenever is the same as the await
ab6tract except that one works, and the other doesn't 11:25
for me
RabidGravy it is the await that is problem
ab6tract do you see the same eternal behavior my initial example, RabidGravy ? 11:26
ah, good to know...
11:27 laz78 left
ab6tract well, it's still broken for me :S 11:29
RabidGravy now I'm curious as to why the promise returned by start isn't working for the await 11:30
ab6tract RabidGravy: gist.github.com/ab5tract/d730a845a3915f7abdcf 11:31
in my experiments, it seemed to also be related to IO.watch. IIRC, i was able to get the expected behavior when doing 'whenever Supply.interval(1)'
so far my experiment into proving how simply perl 6 is for this kind of async script is not going so well :S 11:32
perlawhirl ab6tract: i get one fooble and nothing more 11:33
however...

perlawhirl if you've ever watched a 'watch' file changes actually trigger something like 3 events really quickly 11:34
ab6tract perlawhirl: ... stable? :S
perlawhirl dunno, maybe that is causing some issue
stable waits until watch has been stable for n seconds 11:35
moritz the file events are *very* OS-specific :/
ab6tract could be. in my script i added a %seen lookup and use that in my whenever
perlawhirl so when you get that sudden rapid triger of 'watch' events, it waits until they are stable for a while
11:35 xpen left
ab6tract perlawhirl: unfortunately that doesn't help my script's behavior :( 11:36
perlawhirl *shrug* 11:37
do you only get one fooble most of the time?
ab6tract perlawhirl: yes. but for the actual use case in gist.github.com/ab5tract/d730a845a3915f7abdcf, it bails immediately after i copy a .wav file to /tmp 11:38
11:38 cdg left
gfldex if .pod files would be modules, would they be precompiled and the =pod stuff parsed faster? 11:40

YES! that was exaclty my thought
the 'exit' from your proc is somehow propagating to rakudo... somehow... maybe

perlawhirl i have an idea to test... one sec 12:56
hm, nvm... i just tried executing another perl script that exits with an error code as the Proc... the error code did not propogate up, but! unlike the echo, it never gets to the end 12:59
ie... i put a 'say "DONE";
at the end of the foobles scripts
it always says 'foobles' then done
12:59 ajr_ joined
perlawhirl when the Proc i ran was a p5 script that just did 'exit(123)' i never saw DONE 13:00
so yes, i would say the exit signal is bubbling up

hoelzro ab6tract: what kind of weirdness? 14:49
[Coke] flussence: what's your Configure.pl line?
or are you using something other than straight rakudo to build?
flussence I'm using some self-written gentoo packages, but they're pretty much all one-liner Configure commands. rakudo's is "perl Configure.pl --prefix=/usr --sysroot=/usr --backends=moar" 14:50

my config step just completed fine on nom.
hoelzro ab6tract: do you have some example code?
[Coke] I think there's some other thing going on with the gentoo stuff. 14:54
ab6tract yup: gist.github.com/ab5tract/d730a845a3915f7abdcf
flussence pretty much straight away, first thing it prints is the die from line ~52
ab6tract perlawhirl was helping me a lot this morning
[Coke] (I did not use sysroot or prefex... wait, you don't --gen-moar ?)
so are you installing moar and nqp separately and then doing rakudo?
ab6tract he was able to make a smaller case reproduce by Proc::Async'ing a perl script that just did 'exit(123)' 14:55
but the behavior on linux seems to be sane
flussence [Coke]: yes; moar --version prints "This is MoarVM version 2016.01 built with JIT support"
nqp is "This is nqp version 2016.01-RC1 built on MoarVM version 2016.01"
BooK hey ab6tract 14:56
ab6tract hey BooK :)
[Coke] flussence: why are you installing 2016.01-RC1 ?
oh, right, you have no choice there. 14:57
so, the answer is: there is no guarantee that HEAD/HEAD/HEAD always works.
BooK I'll be in A'dam next week!
[Coke] this is why we have versions specified at each level saying which version to work with at the lower level. 14:58
hoelzro ab6tract: I'll give it a whirl on FreeBSD later; that often catches OS X problems =)
[Coke] but you might have similar problems if someone pushes a change to NQP that rakudo isn't ready for.
Skarsnik gah libminixml is annoying to use ><
[Coke] ... that said, let me try something. 14:59
... nope, nqp's VERSION is 2016.01, not 2016.01-RC1 15:00
ab6tract hoelzro: cheers! thank you :D

hoelzro donaldh: so how is it that CompUnit::Handle's module_ctx ends up holding a ContextRef? 16:18
azawawi Skarsnik: it is delayed... travis ci has already finished all those builds :)
donaldh hoelzro: that's what it's meant to hold, no? 16:21
hoelzro donaldh: I have no idea; I just know that ContextRefs aren't supposed to be serialized, right?
azawawi so we do not have any destructors just LEAVE phasers, right? and DESTROY submethod is pretty much useless to native code handle cleanup
donaldh hoelzro: but the whole CompUnit::* subtree should never be serialized into a CompUnit AFAIK.
Skarsnik azawawi, you can still have destroy, it will maybe called at some point 16:22
hoelzro ahhh
Skarsnik just not when going out of scope like in c++
hoelzro so that %instances assign somehow makes nqp-j think that they should?
azawawi at least java has finalize 16:23
16:23 mohae joined
hoelzro azawawi: how is finalize different from DESTROY? 16:23
donaldh hoelzro: Well, assigning to "my %instances" in the CompUnit::Repository::Locally role causes a reposession of that hash into the compiling CompUnit's SC. So that pulls a bunch of CompUnit::* objects into the compiling SC. 16:24
hoelzro ah ha
azawawi well DESTROY seems never to be called
Skarsnik never sucks x)
it should still be called x)
hoelzro azawawi: it does, but it *may* not be called if the program exits and you don't use --full-cleanup
donaldh wonders if nqp::neverrepossess is useful here...

donaldh hoelzro: Commenting out L12 of CompUnit::Repository::Locally makes the problem go away. Presumably the side-effect is duplicate CompUnit::Repository::Locally instances for the same $abspath
Skarsnik Someone should write something to extract the diowygen stuff, it could be fun xD
hoelzro I brought up the whole "DESTROY never runs if the program exits" issue a while ago; the concensus, I believe, was that it's very, very rare that DESTROY would do some sort of cleanup that the OS itself doesn't do for you on program exit, and that rarity doesn't justify slowing down the shutdown process 16:29
donaldh: *nod*
flussence wonders if the current DESTROY should be renamed RECYCLE, to free up the existing word for a future where someone figures out how to implement conventional destructor semantics
Skarsnik hoelzro, cute if have a single thread/process
16:29 rarara joined
TimToady that assumes only one interpreter; one would like to support multiple interpreters inside something like apache 16:29
more generally, any embedded interpreter should run all DESTROYs 16:30
hoelzro agreed
I think that's up to the embedder, then
it's kind of why we have --full-cleanup in Moar, right?
perlpilot flussence: I've thought DESTROY needed a name change too. 16:31
jnthn I expect --full-cleanup in Moar will get more properly supported
donaldh Is it possible to initialize "my %instances" in a role?
hoelzro I think the "don't run GC at exit" policy only really applies to the perl6 standalone interpreter that is used to run programs on the command line
donaldh: I wonder if the fact that it's a role has something to do with it; role bodies are kinda funky
RabidGravy hoelzro, and it's a long time since even Perl 5 bothered supporting an OS where it was possibly fatal to exit a program without cleaning up your resources (I'M LOOKING AT YOU AmigaDOS!)
16:32 leont joined
jnthn I also think that too many people want to use DESTROY for resource management, but that should be done explicitly in Perl 6. Yes, we should probably provide a syntactic construct for that at some point like C#'s using, Python's with, etc. 16:32

rarara probably /home/romain/.rakudobrew/moar-nom/nqp/MoarVM/src/io/syncfile.c line 222
hoelzro I would guess it's nqp::eoffh, which Moar implements here: github.com/MoarVM/MoarVM/blob/mast.../io.c#L340 16:45
it could be that libuv implements eof via seek()...for some reason

AlexDaniel perlpilot: good point, I'll add that to the bug report 17:16
perlpilot ZoffixW: because I favor explicit over implicit when there's the potential for ambiguity.
ZoffixW: i.e. if the user really wanted .Int, they should have said so 17:17
ZoffixW perlpilot, but that introduces an inconsistency
perlpilot hwo so? 17:18
er, how so?
ZoffixW perlpilot, see my example above. I've used a Rat for an endpoint index and Rakudo DWIMMED
So the inconsistency would be: we dwim, but only sometimes, the other times you get an error 17:19
perlpilot ZoffixW: sure, but that has nothing to do with rotor :)
ZoffixW I view .rotor withing the entire Perl 6.
*within
17:19 espadrine left
perlpilot Perl has a long history of integerizing indices and it makes sense to continue as such. .rotor has no such history and it's not clear (to me anyway) that auto-calling .Int is what people would generally want when (accidentally?) passing a non-Int to .rotor 17:20
ZoffixW Why accidentally? You'd be passing it for the same reasons you'd pass a non-integer as an index. 17:21
perlpilot ergo, I favor encouraging the user to be explicit and say what they mean rather than have Perl guess
ZoffixW There's no guess, since 1.5 is meaningless.
AlexDaniel which should probably error out?
ZoffixW --- 17:22
perlpilot ZoffixW: clearly it's not meaningless since the current implementation handles it just fine ;)
AlexDaniel “You are doing meaningless stuff in block <unit> at -e line 1”
ZoffixW perlpilot, it doesn't. It's a bug
AlexDaniel, see my original argument about inconsistency.
moritz
.oO( check your privileges in sub foo at -e line 1 )

ZoffixW Your logic would suggest [1..1.5] should also error, since in that context 1.5 is also meaningless

AlexDaniel what is language inconsistency? Whenever I hear about language “rules” I don't really get it. The language developed on its own, there are no rules. Everything we call a “rule” is just an observation that something tends to be this way or another. These made up rules can be inconsistent, but the language itself is probably not.

Juerd Blog posts are often not ass well thought through as you'd like 19:23
timotimo it's only a bad idea when the latest blog post is a year old
Juerd One person's bad mood or suboptimal phrasing can ruin someone's else's chance to take Perl 6 seriously.
ZoffixW I think that's sensationalism :/ 19:24
Juerd Then again, I think there are more suboptimal things about perl6.org and I don't have time to fix them, so never mind my opinion.

RabidGravy I've got a feeling that it probably has a race between the first whenever being fired and the promise that controls the react block being setup 20:01
my best workaround is e.g
m: my $p = Promise.new; my $q = start { react { whenever $p { whenever Supply.interval(1) { say " done"; done; };} }; True }; $p.keep; sleep 1; say $q.status 20:02

richi235 Good Evening
ZoffixW \o
richi235 I have a question about native call and Inline::Perl5
timotimo oh 20:23
okay
richi235 I figured out that Inline::Perl5 starts the perl5 vm/interpreter via native call
timotimo yeah
richi235 Does the perl5 vm run in an own process or "inside" the moarvm process?
timotimo inside it 20:24
richi235 And if it's a own process how is IPC handled? Via shared memory? or via sockets?
ahh kk thanks
moritz it just uses perl's XS "API" (or a slim C wrapper around it where that's easier)
richi235 that was what i wanted to know :)
moritz (note that XS is quite some macros, and you can't nativecall marcos, just functions; hence the C wrapper in some places) 20:25
