Timbus dunno about turning off pthreads for libuv though.. might? be possible

nwc10 sisar: is there a reason why you want a Cygwin Rakudo particularly? MoarVM (and Rakudo) build for native Win32, and there are MSI installers for download at rakudo.org/downloads/star/ 06:46

ChoHag Hmm I tried |%var before. Why does it work this time?
sisar nwc10: oh, ok. No showstopper reasons. Only that I'm more comfortable in Linux, but currently forced to use Windows. Ok, I'll try the Win32 version.
thanks
which MSI should I use ? JIT or no JIT ? 07:03

thank you
ChoHag Can a role have a BUILD (or otherwise fiddle around at construction time) without interfering with construction of its consuming class or co-consumed roles?
lizmat ChoHag: don't think so 08:51
either the class has a BUILD, in which case the role's one will be ignored
and if it doesn't, importing the BUILD will mask the default (inherited) BUILD 08:52
on which the class may well depend
ChoHag So a role's options for acting during construction are nothing at all or everything? 08:53
08:53 itz_ joined
lizmat well, if the class doesn't have its own BUILD 08:54
itz_ morning
ChoHag That's the 'nothing at all' option.
lizmat you *could* "nextsame" it from the role's BUILD, I guess
ChoHag Hmm
lizmat if it does have its own BUILD, you're basically without options, I think
itz_ o/
moritz you could nextame in BUILDALL 08:55

FROGGS .oO( you could nex t'aime BUILDALL ) 08:58
lizmat moritz: aren't we really getting in rakudo specific internals land there ? 08:59
ChoHag Is BUILDALL rakudo-specific? 09:00
lizmat the string BUILDALL does not appear in the specs 09:01
and there are no tests for it in roast
or in the sanity test 09:02
so, it's at least in a grey area :-)

nine lizmat: I'm not sure it's true that a role's BUILD is ignored if the class has one. I came across the same question yesterday and my role's BUILD still gets called after adding one to the class. I just found no way to get the default BUILD in addition to the role's. 09:33

ChoHag Something in thi chain of terminal/ssh/tmux/irssi is confused by all these weird characters.
My money's on irssi.
Makes copying text a PITA because the mouse is buried at the back of the desk. 09:40

ChoHag The above don't work if B is a role punned into classhood.
'No concretization found for A'
lizmat ChoHag: so A and B are both roles ? 09:45
RabidGravy it was correctly pointed that if one has a Build.pm with "class Build is Panda::Builder { ... }" then "panda" should be in the build-depends for the convenience of other installers than panda
ChoHag Probably. I'm not convinced one way or the other on the inheritence vs. composition. 09:46

lizmat please don't attribute to malice what you can attribute to NFG happy people
[Tux] is one of the people who figured how to print (ASCII) text upside down using readily available Unicode characters 09:49
ChoHag No Freaking Good? Non-Functional Gear?
lizmat Normalization Form Grapheme
ChoHag Not Fully Guaranteed?
lizmat it was one of the three main things to be done before we can release Perl 6 09:50
and jnthn++ did it
[TuxCM] ChoHag, what is your problem with my Unicode message?
jkva w00t
ChoHag It screwed up my terminal somehow and all I saw was that.
I think irssi's a bit shit and is fighting somehow with tmux.
[TuxCM] maybe your terminal in not (fully) Unicote capable? 09:51
jkva ChoHag: reminds me of when PuTTY borks on some unicode chars
lizmat wish jnthn had put is OSDC.no NFG lightning talks slides online
[TuxCM] sorry for that
ChoHag Something isn't.
I don't care anywhere near enough to fix it.
If something goes wrong enough there's /clear and logfiles.
lizmat .tell jnthn seems jnthn.net/articles.shtml is in need of an update :-) 09:52
yoleaux lizmat: I'll pass your message to jnthn.
[TuxCM] FWIW that message was the output of a "normal" ASCII text filtered through my 'uchar -d' script that puts random (valid) diacriticals on every letter
ChoHag But out of curiosity, can you do whatever you did again so I can see what my non-tmux'd alter-ego makes of it?
Oh looks like it was a quit message...

only 512MB on the RPi B model

RabidGravy I have a RPi B with Fedora on and it will build and run rakudo but ridiculously slow 10:36

azawawi single core performance is like an Intel Celeron M 1.00GHz... pretty slow lol 10:44
jdv79 i think mine is "Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz"
4 core looks like 10:45

itz_ does gcc even use extras cores?
azawawi gcc -j num_of_jobs # maybe? 10:48
jdv79 the middle manager is causing trouble

I guess you should be able to parameterize a SetHash

yoleaux 09:52Z <lizmat> jnthn: seems jnthn.net/articles.shtml is in need of an update :-)
ChoHag_ Can attributes or variables be defined with a where clause or am I thinking of Moose?

Which compound types can be parameterised? 13:14

well i hated it lol and it was confusing lol
ChoHag_ So something like a type-constrained SetHash is eminently possible but unimplemented? 13:18

Deprecate Socket.send in favor of Socket.print

Users may confuse the send method (which is just a Str-friendly wrapper over write) with send(2), which is subtly different from write(2). To avoid this confusion, and open up the possibility of a true send(2) analogue in the future, I think that the current send should be renamed to print (thanks to jnthn++ for the suggestion)		 13:36

lizmat note that this version of BUILD actually sets the attributes befpre checking them 19:54
(in the signature)
ChoHag_: is that what you had in mind?
ChoHag_ That's exactly what I had in mind. 19:55
Except that having a BUILD method is out because the roles trample all over each other.
lizmat there you go: I guess you also want to check for values <0
ChoHag_ That was more or less my plan A.
plan H or I or something is to use real classes rather than a pun, but I'm not that far down the alphabet yet. 19:56
lizmat Perhaps then Triangle should be a class, and you should use "handles" ?
ChoHag_ handles as in method delegation?
lizmat yes
ChoHag_ Hmm. 19:57
I shall see what plan C becomes.
But tomorrow. I'm being huffed at by the wife for sitting here with the light on.
lizmat m: class A { has $.x }; class B { has A $.a handles <x> }; say B.new(x => 42) 19:58

lizmat m: class A { has $.x }; class B { has A $.a handles <x> }; say B.new(a => A.new(x => 42)).x # this works 19:59
camelia rakudo-moar f7cdcd: OUTPUT«42␤»
lizmat I guess one could argue that the default .new would need to know about attributes that handle methods?
is this a bug, a NYI, something not thought of yet ? 20:00
ChoHag_ It's quite reassuring (literally - I'm not being sarcastic and am too out of it to apply the standard social filters) when even the people making perl 6 make syntactical mistakes.
Because sometimes this language is fucking weird.

lizmat I guess the trick is OUTERS::<$_>
I guess there are some hidden levels in the CATCH processing so that OUTER:: is checking the wrong scope 20:08

lizmat for president! Thank you! :-))
lizmat afaik, TimToady implemented OUTERS:: so, he would need to be president 20:09
pippo :-))
lizmat but since he is benevolent dictator already, there is not much point :-)
RabidGravy It would also be nice if the CATCH could be pointy
pippo :-))
lizmat and then keep the outers $_ ?
brrt no reason a dictatorship can't also appoint a president. i think the soviet union did that 20:10

jnthn lizmat: On the proto method new things you removed, they hid (and so rule out) the default constructor inherited from Mu. 20:33
pippo jnthn: Interesting. Thank you.
lizmat jnthn: but the removal did not cause any spectest breakage 20:34
so it's an optimization ?
jnthn lizmat: Well, I suspected you've have spectested, but I was about to add that I couldn't see any cases where it'd have made a difference.
20:34 yqt left
jnthn lizmat: Maybe, only thing that's bothering me is that one was in array, and I wrote that recentlyish, but I can't remember why on earth I put a proto there.. 20:35
lizmat there were some cases I could not remove the proto without breaknng things

jnthn Hm, no damage there :)
Dunno what I was thinking.
:)
lizmat well, me neither, and if it was not because of an optimization, then we should be better now, right ? 20:36
but if you're not comfy with it, a revert is done easily :-)
jnthn lizmat: I'm not uncomfy with your patch, more curious what I was thinking. But I think I did have to insert a bunch of proto methods in array in general, and maybe it was just cargo cult :) 20:38
lizmat: I doubt I'd have done it for optimization since it's...barely one. After the first dispatch or so we'd hit the cache.
lizmat so, proto creates a local dispatcher 20:39
jnthn Right, and hides any candidates from the base classes.
vendethiel (from user-land) only creates proto when it's not for { * }
lizmat wouldn't it be simpler to make the sig on the methods more specific ?
jnthn Well, it already *is* 20:40
For array at least.
lizmat class A { multi method new(A:) { } } ?
jnthn That's the default.
lizmat then I don't understand why yoy would want to hide candidates 20:41
jnthn So the Mu constructor is already unreachable for array.
Well, in the array case I don't
But in other cases you may
For example, if the base class had a method that took exactly two parameters, I think by arity that beats one in a subclass that takes the invocant and a slurpy 20:42
(in the array.new case, that is)
Anyway, as far as I can tell the patch is harmless.
(And so we do the same thing with less code, which is good)
lizmat
.oO( mostly harmless )
well, yeah, that was the idea: less code to maintain for the same effect, is good 20:43

[Coke] reads brrt-to-the-future.blogspot.nl/2015...ilers.html and wonders if result = LOCAL[8]+12 should have (const 12 int_sz) instead of (const 8 int_sz) 20:54
TimToady thinks Pos is kind of a bad name, given that it could be taken to mean "Positive" 20:55
20:56 dha left
[Coke] "maybe we could call it StrPos" *duck* 20:57
lizmat [Coke]: it's not only for Strings
ShimmerFairy I imagine "Index" (or shorter "Idx") would be a good alternative. 20:58
[Coke] I know, just a callback.
Tcl calls it ind... what ShimmerFairy said. And I would prefer Index, not Idx.
lizmat Index would work for me
it share In with Int
TimToady I would prefer that to Pos
jnthn I'm fine with Index
lizmat ok, then I'll make it Index and get the testing done 20:59
ShimmerFairy [Coke]: I only suggested Idx because 1) I tend to use that abbreviation, and 2) In case people liked keeping it to three letters for some reason :)
jnthn My head is somewhat sympathetic to masak++'s concerns on the Index thing, but my gut feels alright with it :) 21:00
[Coke] is any index false?
(just an undefined one?)
lizmat undefined 21:01
and that would mean False
TimToady or arguably that's a good time to return Nil
lizmat Nil would be fine by me
21:02 dha joined, abc-xyz joined
TimToady we like to distinguish missing from uninitialized 21:02
lizmat I think the code returning Int predates the existence of Nil 21:03
