am i triggering some sort of infinite recursion? or infinite loop? or something like that? 07:30
a throw-rethrow-loop maybe?

moritz 122250 is probably spam
08:53 grettis left
timotimo that one i can see 08:55
jaffa4: i'd be interested to know where you got the inspiration to use a multi sub for your TopWindow_TopWindow_c?
also, it seems weird to me that you'd want to hand back an OpaquePointer from the new method of your TopWindow 08:56
jaffa4 from C++ and this function is exported as C functrion , that is why _c
FROGGS jaffa4: but why is it a multi? 08:57
jaffa4 because c++ can have overloaded functions
and if they are important, this does not compile
imported
timotimo how does the C front-end deal with that?
jaffa4 by numbering the functions... the name because fuctionname2, functionnam3... 08:58
timotimo i wonder if multi subs work properly with nativecall
FROGGS timotimo: yes, they should
at least the MMD works... 08:59
08:59 wenca left
jaffa4 what is MMD? 08:59
FROGGS and you have to know symbols the C libary exports, whatever they are
timotimo multi method dispatch
FROGGS which is also in use for subs actually 09:00
jaffa4 so this is a bug, right? 09:03
timotimo yeah
but still, why "returns OpaquePointer"?
09:03 grettis joined
FROGGS but also, returning something from new that is not an instance of that class is wrong 09:04
jaffa4 not sure, maybe because I played with it to make it work
timotimo ah
FROGGS: only morally wrong, though :)
FROGGS yes :o)
jaffa4 even if it retuens TopWindow, it does not work 09:08
timotimo oh, could it perhaps have to do with * instead of ...? 09:09
jaffa4 no
timotimo OK
strange.
definitely strange.

Ulti whoa since those changes to list iter (I assume) my tests take 24 seconds instead of 32 YAY #perl6++ 09:19

gtodd carlin: hmm when you say "X" do you mean X as in "x.org" ? :-D 14:42
ChoHag Considering the fucked up dependencies some apps or libraries have, a mere language which happens to be pretty much ubiquitous already is hardly overkill.
btyler since in the case of discount, it needs a particular configure flag (--shared) so NativeCall can work with it

[Coke] rakudo parrot horribly broken. only -8- passing tests. 16:28
carlin woah :(
[Coke] jvm: down to 91 failures; moar - 69; moar-with-jit the favorite at 68 16:29
carlin did moar fail an extra flappy test? or is there actually a test that moar-jit passes that moar doesn't? 16:30
[Coke] first few failures at least in parrot are complaining about Cannot call 'say'; none of these signatures match:
:(Obsolete:D: *%_)
:(Mu: *%_)
carlin: too many fails at the moment for me to investigate that one.
you can, however: check out github.com/coke/perl6-roast-data/b...ummary.out vs. github.com/coke/perl6-roast-data/b...ummary.out 16:31
looks like test file is S17-supply/start.t 16:32

jaffa4 Is there compartible format with int32? 16:58
TimToady native integers should just work as if promoted to Int, as far as formatting goes, though of course the optimizers is allowed to bypass that 17:00
*zer
TimToady is guessing what you mean by "compartible" though
[Coke] latest rakudo does not fix parrot failures.
17:02 Alina-malina left
jaffa4 compatible... 4 is not translated into int32... what type can I use which is the same as int32 but 4 can become it? 17:02
17:03 brrt left, Alina-malina joined
TimToady the fact that 4 cannot become an int32 is simply a bug, in my estimation 17:03
jaffa4 Have you read today\s conversion? 17:04
moritz how should it become an int32?
TimToady yes
FROGGS[mobile] A string is also accepted as Str and str...
but str is not a subset 17:05
TimToady native integer types are to be treated as storage types, which are like coercion types based on Int, but we're still weak on coercion types
I consider int32 to be int32(Int)
jaffa4 the method could accept Int... then cast it into int32.... 17:08
TimToady that's precisely what the int32(Int) notation means 17:09
17:09 ajr_ left
TimToady but it's NYI 17:09
jaffa4 m: print int32.min; 17:10
camelia rakudo-moar c3bd13: OUTPUT«Inf»
jaffa4 m: print int32.max; 17:11
camelia rakudo-moar c3bd13: OUTPUT«-Inf»
TimToady note, however, that if you have both int32(Int) and Int variants in multis, the Int is the same nominal type, so we'd have to treat the coercion as a constraint if it were going to try that first
otherwise it'd be formally ambiguous
jaffa4 m: print Int.max;
camelia rakudo-moar c3bd13: OUTPUT«-Inf»
jaffa4 m: print Int.min;
camelia rakudo-moar c3bd13: OUTPUT«Inf»
jaffa4 Is that ok?
TimToady that looks like an accident 17:12
m: say [max] Int
camelia rakudo-moar c3bd13: OUTPUT«-Inf␤»
17:12 grettis joined
TimToady it is not clear to me that it should allow type objects in that 17:12
m: say [max]()
camelia rakudo-moar c3bd13: OUTPUT«-Inf␤»
TimToady it's treating the type object as (), or some such, which seems bogus 17:13
moritz iirc min and max just ginreo type objects
*ignore
TimToady that seems wrong
should probably require .DEFINITE or fail 17:14
especially since it produces the opposite of the right result here
we ought to be able to get the bounds of Int as -Inf..Inf, but probably not that way 17:15
jaffa4 Is it possible to get maximum, miinimum value of a type in Perl 6?
TimToady likewise uint32 should give bounds of 0..^2*32 17:16
PerlJam jaffa4: what would Mu.max be? or Str.max? ;)
jaffa4 when it makes sense
TimToady we could define .range on some type objects 17:17
17:17 grettis left
TimToady Str should probably return '' .. Inf or so, depending on whether we end up with a StrInf 17:17
though arguably "\x10ffff" would work for that value as long as you squint :) 17:19
PerlJam And Mu would return Mu .. Mu ? 17:20
TimToady Obviously it should just sit there and look at you till you walk away 17:21

gtodd what does "~" do to $/ in ~$/ .... ?
moritz lizmat: min and max are some of those heretic operators that work on strings and numbers
gtodd: it forces it to be a string
lizmat: which makes things more awkward
geekosaur $/ is a match object. if you are expecting a string, you need to explicitly ~ it (or .Str) 20:37
moritz lizmat: maybe the best thing to do is always feed the argumenst to infix:<cmp>, and let it figure out all the dirty details
gtodd oh yeah it's short for $/.Str is there some can I see what the parser does ? does it do the same thing?
moritz what which parser does?
itz_ geekosaur: there should be an atom feed in place now .. just looking at rss
geekosaur thanks 20:38
gtodd hehe I mean can I do like perl5 and Deparse 20:39
geekosaur oh, er, where? doesn't seem to have meta information pointing to it and /rss and /atom don't work...

20:48 anaeem1 joined
moritz gtodd: I'm not sure why we need that distinction 20:48
gtodd moritz: we don't :-) I'm just got used to using Deparse to see what perl5 thinks a piece of code is 20:50
moritz gtodd: well, a Perl 6 deparse would just tell you that ~$/ calls prefix:<~>($/) 20:52
gtodd: but what prefix:<~> does is not part of the syntax; rather it's part of the runtime library 20:53
gtodd ok ...it's different :-) ... A better question would have been: how can I "see" how perl6 runs code ? e.g. what ~ does to things I put it in front of " ... but I still would get a good answer so thanks :-) 20:55
itz_ geekosaur: thanks that should be discoverable
geekosaur gtodd, I think the way perl 6 is mutable defeats you here 20:56
moritz gtodd: by using the debugger, and stepping through the code 20:57
geekosaur that is, that things like prefix ~ can be defined in the language
best you can do is step through it and see what it all resolves to after dispatching etc,

dalek line-Perl5: 5665403 | nine++ | / (3 files):
Infrastructure for inheriting from Perl 5 classes in Perl 6

Add an invoke method that allows separating method lookup from parameter passing. This allows using the wrapped P5 object for method lookup while passing a wrapped P6 object that inherited from the P5 class as first parameter thus making polymorphism work.		 21:20
line-Perl5: 457136e | nine++ | t/inherit.t:
Use Moose in inherit.t for fun and showing that it indeed works
nine PerlJam: try it for yourself :)
Now we just need a little sugar so not everyone has to add this fallback stuff to her classes. 21:21
timotimo so ... a newcomer to both perl5 and perl6 shows up and builds a perl5 interoperability framework in just a month? 21:22
nine timotimo: I'm certainly no newcomer to Perl5 :) Been using it for 15 years. And I'm the maintainer of Perl 5's Inline::Python which is how I know how this may work. But I really have no clue about Perl 6 ;) 21:23

that explains it

timotimo nine: if we have Inline::Python2 and Inline::Python3 both, we could allow people to migrate their code piecemeal from 2 to 3 (to 6)
PerlJam takes kids hither and yon & 21:27
nine timotimo: the funny thing is, that Perl people usually quickly come up with an idea on how to allow a Python 2 -> 3 migration: run the other interperter in a separate process and send data between them. That's at least the idea I've heard when talking about Perl 5 <-> 6 interop. We just don't need to go that far in Perl :) 21:28
Maybe before they finally discover that, we should implement an Inline::Python for Perl 6 :) 21:30

22:08 bluescreen100 left
nine leedo: looks like that goes in the right direction. But you cannot enumerate all methods of an arbitrary Perl 5 class. It's too dynamic with features like AUTOLOAD. You can just try check if a method with a given name exists. 22:11
leedo nine: yeah, i was thinking it could accept the name of a constructor 22:13
and/or a whitelist of method names 22:15

if we sort the work queue by address in a full gc run

masak hoelzro: as far as I know, hooking RT in here has never been tried. 22:25
hoelzro: could probably be made non-chatty (as in, only one line of output per ticket change)
if it's done, I would kinda hope it were done as a p6 bot.
