zachk whats a good perl6 editor, vim seems really slow out of the box00:03
sena_kun emacs has perl6-mode. :P also, there is Atom, Comma(in beta though) and others. You can find a list at https://github.com/perl6/user-experience/issues/19#issue-31100571800:05
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.00:07

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 work12:49
moritz PSA: the Perl 6 regex/grammar books is fore sale today, USD 9,99: https://www.apress.com/us/book/978148423227912:56
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]12:57
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 memcpy13:00
but this is not really an issue13:00
the real issue is when the error does not show up and instead you randomly get Internal error13:00

← Ven`` left13:06
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 Pointer13:11
of course you can also use nativecast instead of typed pointer13:12
but then one wonders what is the use of them13:12
and to gain write access you are left with only memcpy13:12
→ caa51h joined13:12
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 sizes13:46
2) C-based exceptions (including perl exceptions inside C callbacks)13:46
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.13:47
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

sena_kun $foo // 'default-value'20:04
Altreus thought so, but hard to google :)20:04
sena_kun also `with $foo {} else {}`20:04
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 feature20:05
Altreus oh I could do with $foo { return stuff } return 120:07
that shortens it a lot actually20:07
timotimo if it's $foo that you return, you could probably also ".return with $foo"20:07
Altreus it ain't :)20:09
timotimo or based on $foo i guess :)20:09
Altreus wait, you can call return on things?20:09
timotimo hum. i never ended up making a module out of my cool tunnel operator20:09
