vrurg SmokeMachine: is it same rakudo version used by travis and with manual testing? 01:52
SmokeMachine vrurg: I'm running the same docker image/container...
vrurg SmokeMachine: but most certainly it gets a non-code in $meth. The only way to find out – is to print $meth. If I get time I would try to commit a "patch" and see what the output in travis would be. 01:53
SmokeMachine vrurg: I know it's working... but I'm afraid of merging it and the bug goes to master...

jmerelo We're halfway there; anyone interested, please add yourself to the advent calendar schedule via PR 06:02
vlad78 Hi 06:03
I'm trying to find instructions on how to compile raku from sources
Latest git, not rakudo star
moritz vlad78: perl Configure.pl --gen-moar
make
make install
vlad78 moritz: that downloads moarvm or do I have to have it cloned in advance? 06:04
s/cloned/clone/
jmerelo vlad78: if you want to compile from source, you're supposed to have the source already... That does not download anything. 06:06
vlad78 jmerelo: Right, in that case what all packages do I need to download and where?
I'm aware of 'raku' and 'moarvm' 06:07
jmerelo vlad78: unless you want to do it yourself for some reason, I stronly advise to use something like rakudobrew... Will simplify stuff a lot.
vlad78 Right, /me googles rakudobrew
The thing is that I have tried to compile raku on solaris, and in current rakudo star is nasty bug in hostname resolving routine 06:08
But the current git has the code very different, probably fixed
jmerelo so you need HEAD as opposed to other 06:09
With rakudobrew you can install the point versions. 2019.07.1 is the latest
Ulti vlad78: p6env is also a useful choice especially if you want multiple versions for different projects 06:12
vlad78 All right, thank you all. I'll try rakudobrew, and if it fails just wait for next star release :) 06:18

guifa2 is making an e-mail token for regexen. Good lord we have come a long way in terms of designing formats 14:30
"<1234 @ local(blah) .machine .example>" (spaces intentional) is a valid e-mail address 🤦 14:31
14:34 Manifest0 left 14:35 Manifest0 joined 14:36 Manifest0 left
[Coke] O_o; 14:37
is it distinct from the version with no spaces? 14:39
Grinnz never forget: metacpan.org/release/Email-Valid/s...m#L399-400 14:40
[Coke] I am all in on never validating email except by trying to send an email. 14:41
14:42 warriors joined
guifa2 [Coke]: I'm more or less the same. But I was thinking one of the strengths of Raku is the ability to create some fairly powerful reusable tokens (the coolest so far I'm saving for advent calendar), and e-mail address is a fairly "easy" one to tackle to show its utility 14:43
[Coke] nice.
Do we have enough volunteers for the advent calendar this year? 14:44
guifa2 The goal (mostly working so far is to go "use Regex::EmailToken" and then [email@hidden.address] ~~ /My e-mail is <email>/; say $<email><domain> ---> "foo.com"; would work both in general code and inside of grammars! 14:45
14:46 pmurias left
guifa2 And I figured out how to grant dot access to the matches too, so the above could have say $<email>.domain, or $<email>.has-domain-literal , etc 14:46
(the dot access is I think the coolest bit I figured out, by wrapping tokens to provide a mixin) 14:47

thanks
tony-o jnthn: i ran a bisect on that commit regarding boundary issue and i think the regression is in 2019.03 and not actually in that PR, the test also passes fine on HEAD rakudo 15:14
re: cro routing boundary PR12 15:15
15:23 lil joined
jnthn ZzZombo: Maybe something like "Only a single whenever block may be running at a time for a given instance of a supply or react block. This means one can reliably write event processing code without races over the state declared inside the supply or react block. However, it also means that a long-running whenever block will prevent processing of further messages until it has completed." 15:29
ZzZombo Is this correct: `@names.sort({ %sets{$_} }).sort({ %matches{$_} }).reverse;`? Doesn't the second `sort` call just override the previous? 15:34
jnthn Yes, seems pointless
tony-o: Hm, interesting...thanks. Will take a look later. 15:35
Grinnz unless it's a stable sort and they aren't all uniquely ordered?
ZzZombo Another docs issue then. Will fix tomorrow. Gotta go to bed. Cya!
jnthn Should probably be `@names.sort({ %sets{$_}, %matches{$_} }).reverse`
Kaiepi any experts on how types are handled in raku on? 15:38
jnthn Well, I designed/implemented most of the MOP, which isn't unrelated. :) 15:40
Kaiepi yeah this is to do with a niche scenario when using the MOP
so
m: class FooHOW { method new_type() { my Mu:U $ := Metamodel::Primitives.create_type: self.new, 'Uninstantiable' } }; FooHOW.new_type
camelia Died with X::TypeCheck::Binding
in method new_type at <tmp> line 1
in block <unit> at <tmp> line 1
Kaiepi there's nothing wrong with this 15:41
i haven't told the type to behave like Mu so it shouldn't type check as such
but
m: sub foo(Mu:U $ --> 1) { }; class FooHOW { method new_type() { Metamodel::Primitives.create_type: self.new, 'Uninstantiable' } }; say foo FooHOW.new_type 15:42
camelia 1
Kaiepi why does this type check?
jnthn In many places, Mu is taken to mean "don't even bother checking" 15:43
Because everything (should be) Mu
So the checks are simply optimized out.
This is allowed. 15:44
I guess the variable typed with Mu:U path is one where that optimization simply doesn't happen.
(I can kind of guess why; it's a bit harder to make it happen.)
Kaiepi is a library for a type that always succeeds type checks against it, but can't be used for anything outside of type annotations a bad idea? 15:46
jnthn Not sure I see the point of it, tbh 15:48
I bet `my Mu $ := ...` would also work out
Kaiepi m: class FooHOW { method new_type() { my Mu $ := Metamodel::Primitives.create_type: self.new, 'Uninstantiable' }; method shortname(--> Str:D) { 'Foo' } }; say FooHOW.new_type 15:49
camelia Cannot find method 'gist' on '': no method cache and no .^find_method
in block <unit> at <tmp> line 1
Kaiepi m: class FooHOW { method new_type() { my Mu $ := Metamodel::Primitives.create_type: self.new, 'Uninstantiable' }; method shortname(--> Str:D) { 'Foo' }; method find_method(Mu:U $type is raw, Str:D $name) { Mu.HOW.find_method: Mu, $name } }; say FooHOW.new_type 15:50
camelia Too many positionals passed; expected 1 argument but got 2
in method shortname at <tmp> line 1

Kaiepi m: class FooHOW { method new_type() { my Mu $ := Metamodel::Primitives.create_type: self.new, 'Uninstantiable' }; method shortname(Mu:U $ --> Str:D) { 'Foo' }; method find_method(Mu:U $type is raw, Str:D $name) { Mu.HOW.find_method: Mu, $name } }; say FooHOW.new_type 15:51
camelia (Foo)
Kaiepi ah
there we go
tony-o [Coke]: do you need anyone for the advent calendar? 15:52
guifa2: did you look at using an action with your grammar to provide an email type object back? this would make it so you don't have to mixin or wrap grammar tokens 15:53
Kaiepi thanks jnthn
[Coke] tony-o: I don't need anything, just curious 15:54
guifa2 tony-o: I definitely did, and will probably still provide such an object. The catch is, actions can't be used in adhoc regexes, only in grammars
AlexDaniel [Coke]: jmerelo seems to be taking care of it 15:55
as for volunteers, you never know :) 15:56

guifa2 tony-o: the actions route is what I took for the <local-number> token for Intl:: stuff when I did it a few weeks ago, but tbh the ability to quickly access the super important stuff seems worth it the wrap+mixin trouble 16:00
16:01 patrickb joined
tony-o ah, you can always call the actions manually from the resulting regex's match object 16:05
guifa2 true, but that's like a whole extra line of code for the end-user ;-) 16:06

tyil that would work for me 22:16
thanks!
22:18 ctilmes joined
tony-o the way to do nested is with a tilde in case that comes in handy 22:18
ctilmes tony-o: Hmm.. .execute just does a "get handle from pool, do thing with it, return handle to pool". I may have to add some diagnostics 22:19
tony-o i'll add them, i'm running a script that is copy all of the META info from p6c to a database so zef can query it and it's doing 881 modules * however many times the version line changed in the META 22:20
that way i can do a fix instead of just complaining that it is dying :-)

jnthn vrurg: I'm about-ish. About the example you showed, that's just because the default package is GLOBAL :) 22:30
vrurg jnthn: I'm about to open a problem-solving ticket. It doesn't look right to me. 22:48
22:50 guifa2 joined
jnthn m: say ::?PACKAGE 22:51
camelia (GLOBAL)
jnthn Why the problem-solving issue? So I can write the same thing I did here and close it? :)
(If there's more to it than this, then sure. If that's all there is, then that's the answer.) 22:52
vrurg jnthn: I'm still checking if I'm not mistaken about the outcomes of this design. 22:53
jnthn: ok, it only now that I got time to check it and though confusing it seemingly harmless. Though it still feels wrong and I would only allow `our $*foo` to be visible by dynamic lookups. Don't see the reason for current behavior. 22:59
Except that it could serve as an alternative solution for people asking for $* to be EXPORTable. 23:01
jnthn vrurg: It's long established that the * is removed from the name when doing lookups in GLOBAL and PROCESS. 23:02
That's how $*IN resolves to $PROCESS::IN 23:03
vrurg jnthn: I know. I only wonder what was the original purpose of this. Just to provide means for the above resolution?
jnthn Yes; it'd be really quite annoying to have to write PROCESS::<$*IN> instead 23:04
Not sure I follow the exportable thing: can't you already do `my $*foo is export`, or bind such a dynamic variable into the hash returned by sub EXPORT? 23:05
vrurg m: module Foo { our $*foo is export = "foo" }; import Foo; say $*foo 23:07
camelia (Any)
vrurg I don't remember if this is a bug or intended behavior. 23:08
jnthn m: module Foo { my $*foo is export = "foo" }; dd FOO::EXPORT::DEFAULT.WHO 23:09

camelia Stash element = {"\$*foo" => Any}
jnthn Hmm...that feels more like bug to me 23:10
vrurg Anyway, when I once was thinking about exporting dynamics, some unpleasant side effects was coming into mind. Unfortunately, it was long ago and I can't remember what seemed wrong to me then. 23:12
That's why this looks more appropriate to me now: 23:13
m: module Foo { our $foo = "my default"; sub foo is export { if $foo == 1 { say "ok" } } }; import Foo; my $*foo = 1; foo 23:14
camelia Cannot convert string to number: base-10 number must begin with valid digits or '.' in '3⏏5my default' (indicated by ⏏)
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
Xliff jnthn: Can you do multi subs with different signatures. Something like: multi sub func-with-callback( &func(Int, Str, gdouble is rw) ) and multi sub func-with-callback( &func(Str, Pointer --> Pointer) )
??
vrurg m: module Foo { our $foo = "my default"; sub foo is export { if $*foo == 1 { say "ok" } } }; import Foo; my $*foo = 1; foo
camelia ok
vrurg m: module Foo { our $foo = "my default"; sub foo is export { if $*foo == 1 { say "ok" } else { say "not ok" } } }; import Foo; foo 23:15
camelia Dynamic variable $*foo not found

Xliff m: module Foo { our $foo = "my default"; sub foo is export { if ?$*foo == 1 { say "ok" } else { say "not ok" } } }; import Foo; fo
camelia 5===SORRY!5=== Error while compiling <tmp>
Undeclared routine:
fo used at line 1. Did you mean 'fc', 'so'?
Xliff m: module Foo { our $foo = "my default"; sub foo is export { if ?$*foo == 1 { say "ok" } else { say "not ok" } } }; import Foo; foo
camelia not ok
vrurg Xliff: right, but the idea is that `our $foo` must end up in GLOBAL and be available via $*foo. 23:17
Like in this simple snippet:
m: our $foo = 42; say $*foo
camelia 42
jnthn m: multi foo(&a:(Int)) { say "i" }; multi foo(&a:(Str)) { say "s" }; foo -> Str { }; foo -> Int { }; 23:19
camelia s

jnthn Xliff: ^^
Xliff jnthn: Would that work without the colons and an "is native" trait? 23:20
jnthn If you don't put the colon then you're trying to do an unpack 23:21
This won't go well
Xliff I've been using that without colons successfully for GtkPlus 23:22
jnthn Hm, that surprises me
I wonder if NativeCall is doing something special there
Xliff I would suspect so. If I use a colon, it doesn't work.
jnthn D'oh.
I don't think `multi` and `is native` go together too well, though that may have been addresed. 23:23
Xliff Ah. That's what I was worried about. 23:24
23:31 maggotbrain joined
jnthn Mostly I see modules write multis as the external interface and then call the appropriate native thing within them 23:32
23:32 maggotbrain left
jnthn Been a while since I wrote a native binding... 23:32
Xliff Yes, but there are times when I need to call a routine that has a nullable callback.
Which means I need two definitions: one with the callback and one with the callback replaced by Pointer. 23:33
jnthn Maybe 'cus folks use the ones I write and then ask hard questions... :)
Xliff Can I use the ones I write and still ask hard questions?! :)
