zachk whats a good perl6 editor, vim seems really slow out of the box 00:03
sena_kun emacs has perl6-mode. :P also, there is Atom, Comma(in beta though) and others. You can find a list at github.com/perl6/user-experience/i...-311005718 00:05
at least I see also Sublime Text, Neovim|Spacemacs too. 00:07
tobs zachk: if you want to stay with vim, be sure to check out the vim-perl6 listed in sena_kun's link. That's sufficiently faster (for me) than what came with vim.

zachk i am getting {a => ｢1｣, b => ｢2｣, c => ｢3｣} in my output from regex matches, i am guessing those funny symbols are supposed to be quotes, is there an option i can pass to perl6 to just use regular quotes for output? 00:34

scovit Is there an alternative way of creating a typed pointer? resp. to my $ptr = nqp::box_i(nqp::unbox_i(nqp::decont(calloc(1, 8))), Pointer[uint64]); 12:48
Pointer[uint64].new does not work 12:49
moritz PSA: the Perl 6 regex/grammar books is fore sale today, USD 9,99: www.apress.com/us/book/9781484232279 12:56
Xliff_ scovit: I've found that typed pointers outside of CStructs are unreliable. 12:57
So I've been using (converted to your case) CArray[uint64]
scovit sometime you need to extract some data from a pointer, then the only reliable solution I found is using a specifically created CArray and a memcpy 13:00
but this is not really an issue
the real issue is when the error does not show up and instead you randomly get Internal error
Unwound entire stack and missed handler 13:01
13:02 kurahaupo joined 13:03 p6bannerbot sets mode: +v kurahaupo 13:06 Ven`` left
scovit Xliff_: what I mean is that in the example above calloc could be anything, and you really need to access the content of a Pointer 13:11
of course you can also use nativecast instead of typed pointer 13:12
but then one wonders what is the use of them
and to gain write access you are left with only memcpy
13:12 caa51h joined
scovit since you can do it with memcpy, one wonders why you cannot do it with nativecast? 13:13

Xliff_ scovit: Ah! Those old gems. "Unwound entire stack and missed handler" can be caused by a lot of things. 13:45
Things I've found that trigger it: 1) Mismatched sizes between C and NativeCall object sizes 13:46
2) C-based exceptions (including perl exceptions inside C callbacks)
scovit: So I really do feel your pain. 13:47
For #2, sometimes the best thing is to hold the exception and rethrow it when you are fully back into Perl.
sena_kun if I have a class A::B in file Foo.pm6, I can re-export it using sub EXPORT into e.g. `ShortB` to use from file Bar.pm6, but I it seems that cannot export `Foo::Bar`, i.e. any multipart name gives me `Could not find symbol '&Bar'`. Is there a way to still do it? 13:49
I still can change a symbol's name with e.g. `class Foo::Bar is A::B`, but it doesn't work with e.g. enums and creates additional overhead(which should be fairly small tbh, but still). 13:52

14:05 [particle] joined 14:06 p6bannerbot sets mode: +v [particle]
scovit can callbacks take as arguments user classes is repr('CPointer'), same as Pointer definition, or is it all handled by pattern matching on the names of the classes? 14:11

if the method above takes the A * equivalent, then it will work just fine. 14:19

Zoffix .tell AlexDaniel the perl6.party domain won't be renewed (expies April 28th). If anyone wants to host the articles elsewhere, the repo is at github.com/zoffixznet/perl6.party . Same as with modules, I don't have plans to preserve the repo, so you may wish to transfer it. 17:36
yoleaux Zoffix: I'll pass your message to AlexDaniel.
Xliff_ Zoffix: This sounds like an ending. 17:40
FWIW, I hope your next endeavour is -Ofun

well, sadly also real life is often like this

notable6 AlexDaniel, Noted!
timotimo the v6.d review was really an awe-inspiring effort
AlexDaniel yeah. 19:23
Xliff_: “Raku” itself is irrelevant in this case, I think, but the reaction of the community to the Raku announcement is what played a bigger role IMO 19:28
I looked at some messages on facebook and they were just cancer
really disgusting to read, and I guess especially so for someone who put so much effort into it
El_Che Yeah, we pretty much failed as a community on this one. But the lack of decisions also plays a role. 19:30

Altreus What's the test for definedness of a variable? 20:04
sena_kun .defined
Altreus danke
sena_kun $foo // 'default-value'
Altreus thought so, but hard to google :)
sena_kun also `with $foo {} else {}`
Altreus, you can use docs site search for such a thing, I think. :) 20:05
leont with is a good example of a small but very welcome feature
Altreus oh I could do with $foo { return stuff } return 1 20:07
that shortens it a lot actually
timotimo if it's $foo that you return, you could probably also ".return with $foo"
Altreus it ain't :) 20:09
timotimo or based on $foo i guess :)
Altreus wait, you can call return on things?
timotimo hum. i never ended up making a module out of my cool tunnel operator
m: sub foo { 5.return; 99 }; say foo
camelia 5
timotimo yes you can
Altreus this language
:D
timotimo though of course since it's a method, the object itself decides what will happen
so if you potentially have to deal with objects that want to do silly or nasty things, just use return %) 20:10

sena_kun scovit, well, I can do gist.github.com/Altai-man/4d96c65d...2b1f10ad67 20:50
although current issue I am facing is that you cannot export multipart names like `A::B`, only `B`. 20:51

you can apparently declare a my constant is export for those
