Cannot resolve caller trait_mod:<is>(C, A, Array); none of these signatures match:
(Mu:U $child, Mu:U $parent)
(Mu:U $child, :$DEPRECATED!)
(Mu:U $type, :$rw!)
(Mu:U $type, :$nat…
ZzZombo <ZzZombo> I just found out you can't call ANY inherited methods from submethods under the pretense that "Virtual method call $.v may not be used on partially constructed object (maybe you mean $!v for direct attribute access here?)", despite the object being constructed a long time ago.
jnthn SmokeMachine: I think that's confused. `my T $a = S` is OK is S < T, but in your case S is Int and T is R[Int] and Int < R[Int] is not true 11:45
*is OK if 11:46
I think you want a subset type, not a role
ZzZombo: Just use self.v instead 11:47
11:48 emeric left 11:50 empT left
ZzZombo Works, but what's the difference? 11:51
jnthn $.x is really just $(self.x), but given $.x looks variable-like, we use it as an indicator that - in a non-virtual context - it's not unlikely that $!x woulda been more correct 11:53
And yes, the error text is a bit specific to some of the cases.
Though it's the most common case 11:54
SmokeMachine jnthn: but how could I make a subset of a dynamic choose type?
And in my case I think subset wouldn’t work... what I’m trying to do is a type that should match the same type of another class’ attribute... 11:56
11:56 zakharyas left
SmokeMachine class User { has UInt $.id }; class Post { has Ref[User, “id”] $.author-id } 11:58
And the Ref type would get the type of User.id and “accept” the same type of it... 11:59
jnthn: ^^
12:00 AlexDaniel left
SmokeMachine Is it possible? 12:00
jnthn Damn that's evil, let me think a moment
SmokeMachine jnthn: why do you think that’s evil? 12:06
12:07 AlexDaniel joined
jnthn SmokeMachine: I meant it in a good way :-) 12:10
So the Really Proper way to do it is to write a custom meta-type
But there's actually a far easier way: 12:11
class Ref { method ^parameterize(Mu, Mu:U $type, Str $attr) { with $type.^attributes.first(*.name.substr(2) eq $attr) { .type } else { die "No such attribute $attr" } } }; class C { has Int $.i }; my Ref[C, "i"] $x = 42; say $x.VAR.of
evalable6 (Int)
jnthn So ^parameterize mixes this parameterize method into the meta-object of Ref, and thus we can decide what parameterization means for this type
12:11 jast left
jnthn And we use it to do the lookup 12:12
And nothing cares that what ^parameterize returns has any relation to the type it was called on, so it just happily takes the returned type :) 12:13
This is also vastly cheaper than a role approach
(If it could be made to work, which I don't think it can anyway)

geekosaur I'm surprised that isn't a syntax error. ^ is not part of the method name, it is part of the .^ operator which invokes a method in the metaclass 12:45
i.e. it's invoking ClassHOW.compose, not C.(^compose) 12:46
more precisely C.^compose means ClassHow.compose(C)
er ClassHOW

SmokeMachine Hi again! I has a problem that I don’t know if it’s a bug or it’s expected... 12:56
m: role Many[Mu:U] {}; class Post {...}; class User {has Many[Post] $.posts}; class Post {}
camelia ===SORRY!===
Cannot find method 'ACCEPTS' on object of type Post
SmokeMachine I had to “fix” with: 12:57
m: role Many[Mu:U] {}; class Post is Mu {...}; class User {has Many[Post] $.posts}; class Post {}
camelia ( no output )
SmokeMachine Adding is Mu on the “stub class”... but shouldn’t it already be Mu?
jkramer I made a little docs patch but I'm not sure how to continue from here. Should I fork the whole repo and send a pull request? 13:00
Skarsnik yes :)
jkramer Also before doing that can someone please review my change and see if it'd be likely to be merged anyway? Maybe I'm completely wrong. :) It's just something I found that should be mentioned in the docs. paste.pound-python.org/show/NrnyAy...tjB8xi72l/ 13:01
Currently it looks like the $start argument is mandatory, but maybe I'm just misreading it. 13:02

Zoffix jkramer: just commit directly. 13:03

ZzZombo jnthn <ZzZombo> why does that NOT die?
Zoffix there's like a billion splice candidates

tyil whats the easiest/recommended way to run a for-loop over multiple threads? just add in start, like `for @args -> $arg { start { do-thing() } }`? 13:18
Zoffix tyil: hyper for @args -> $arg { .... } 13:19
tyil oh neat
jnthn ZzZombo: Because the meta-methods aren't mixed in to the meta-object until compose time
tyil the order isn't important, so i could add in race too, right?
jkramer Is there a difference between `hyper for @args` and `for @args.hyper`?
Zoffix tyil: oh yeah
jnthn ZzZombo: If you want that much control, you'll need to subclass ClassHOW and so forth, as modules like Grammar:Tracer do
Zoffix jkramer: IIRC the latter would be serial 13:20
In a for loop. That's why we added statement prefixes.
moritz why did I just read "in for a loop"? :-)
jkramer Also @args>>... implies hyper as well, right? 13:21
tyil Zoffix: it works as expected, thanks :>
nine So far my travel to FOSDEM has been surprisingly unproductive. Unless one counts the insight that there's just no more low hanging fruit for speeding up csv-ip5xs of course.
Zoffix jkramer: it's a hint to the compiler that it may autothread, but isn't a guarantee and currently that's not yet implemented.
jkramer Zoffix: Ah ok, thanks
Zoffix So FOSDEM is happening right now? Anyone got good information to put into the weekly? 13:22

nine: I'm on my 2nd day in brussels now, trains were pretty empty when I was traveling 13:24

tyil couple of other friends will be arriving today, will be picking them up in an hour or 2

tyil yeah
ZzZombo jnthn, what exactly does `EXPORTHOW` do and how can I make use of it in replacing my class' metaclass?
Zoffix But still, if you use the .map, you won't need to write `race` twice
tyil that does look a bit cleaner 13:29
Skarsnik does binding to a sub finally work with export?
Zoffix Skarsnik: only one way to find out :)
ZzZombo Took a look in Grammar::Tracer, BTW>
Skarsnik Well I can't make this example work x)
tyil does the $^url come magically as the name of the list without the s? 13:30
jnthn ZzZombo: The compiler keeps a hash mapping package declarator (class, grammar, etc.) into meta-objects that say what that type means. Entries are made into it for a given lexical scope. 13:31
ZzZombo: EXPORTHOW is the mechanism by which a module says what entries it wants to make
Skarsnik I wonder if my special branch of GPTrixie still make rakudo crash x)
jnthn Sub-packages of it say what you want to happen
Zoffix m: use NativeCall; module A { our $a is export := cglobal("libc.so.6", "errno", int32) }; import A; say $a;
camelia (Any)
jnthn So for example EXPORTHOW::DECLARE lets you add a new package declarator, which is how OO::Monitors works

Skarsnik x)
Zoffix Skarsnik: ^ that
Skarsnik you created the file?
nine LOL and right after claiming that there is no more low hanging fruit I found a trick to shave off 1 of 4 seconds of csv-ip5xs' runtime
Zoffix nine: :o

Skarsnik timotimo, Yes ^^ I need to practice more, since I will run the game at GSM
Zoffix Skarsnik: yeah
m: "/tmp/meow".IO.slurp.say 13:41

nine It's not particularily elegant though. It's just a new multi candidate for a single positional argument to augment the existing 0 arguments and arbitrary arguments cases
timotimo what's GSM? i only know GSH 13:42
Skarsnik German Speedrun Marathon
timotimo ah, fair enough
Skarsnik marth 28 - 2 april 13:43
nine It does show however that runtime generated code might be the key to gain further generic speedups. Those Captures just are not fast enough. But generating new multi candidates for the actuall calling conditions at runtime is rather simple
timotimo there go my dreams to have rakudo completely unload the compiler in most cases … 13:44
Zoffix making candidates with captures cacheable looks like would produce a ton of win. I see them as reason for slowness all over the shop
13:45 zakharyas joined
nine Zoffix: that sounds like another one of those "suck 4 months out of my life" traps I might fall into 13:46
Zoffix nine: I'm tempted to give it a go too. Though I'm hindered with not having a clue how dispatch and caching works :) 13:47

jnthn nine, Zoffix: I think the answer will be something like exploding flattening things sooner, in-place in the args buffer, for the cases that fit, and putting an interned callsite in place of the flattening one 13:49
Zoffix What's "interned"?
jnthn Look up string interning, then imagine the same for an object representing the shape of a callsite 13:50
Zoffix looks up
jnthn We use those as keys for the multi-dispatch cache *and* for spesh

zeddy__k should I start learning perl6? is it stable enough to develop in? I'm considering perl and perl6 and I like perl6 syntax more, but it's still under development so I'm in a dilemma 14:19
Skarsnik what you want to do with it?
14:19 AlexDaniel left
El_Che zeddy__k: every language that's not dead is under developement 14:20
zeddy__k: perl 6 has production releases since end 2015
depending on what you do, one language may be more applicable than the other 14:21
zeddy__k simple programs for console that read and write to files and mariadb, maybe some numerical work
also scripts that automate some of my daily work
El_Che zeddy__k: I don't see a problem using perl 6 for that (it had a database module and good math support)
Skarsnik not sure there is a module for mariadb? 14:22
El_Che perl5 has more modules as it's been out for a lot longer
moritz s/hd/has/
El_Che Skarsnik: that's mysql
moritz Skarsnik: the mariadb wire protocol is compatible with mysql
Skarsnik at worse you can use a perl 5 module for that
14:22 rindolf left

Skarsnik Hoo ok
no mariadbclient lib so?
El_Che dbish
github.com/perl6/DBIish#mysql 14:23
zeddy__k awesome, thanks
El_Che zeddy__k: stick around while having fun programming 14:24
Skarsnik I mean there is no mariadb c lib to talk to a mariadb like libmysqlclient
zeddy__k is the O'Reilley book inclusive enough to get to an advanced level?
or can I learn more from the docs on the website
El_Che zeddy__k: I picked up from the docs on the website (I have a Perl 5 background) and asking questions here when the doc wasn't clear 14:25
zeddy__k: I recommend moritz beginners book, though, for a shortcut
www.apress.com/br/book/9781484228982
zeddy__k El_Che: thanks
El_Che it's also on safari in case you have that 14:26
moritz fwiw this is book for people who already know a programming language or two, just not Perl 6
El_Che zeddy__k: actually, I found this a nice intro: www.jnthn.net/papers/2015-spw-perl6-course.pdf 14:27
moritz if you want are new to programming in general, "Think Perl 6" is the better intro
also, perl6book.com/ has an overview of the Perl 6 books out there

zeddy__k Zoffix: thanks, I'll check those out too 15:10
jnthn Zoffix: Yeah. Lexpads are immutable, and when we compile a BEGIN we obviously haven't finished the outer block yet, so we have to fake something up. But what? Containers are cloned from a "prototype", and the fake lexpad contains the static container. Thus what's actually happening is that on entry to the scope post-compilation, the Scalar is cloned complete with the value set in the prototype. 15:11
15:11 rindolf left
jnthn Of course, binding doesn't have that level of indirection so there's no way it can work. 15:12
We should perhaps detect it at compile time and say it can't work. Or...we could try diffing the scope after each BEGIN block and trying to somehow propagate bindings.
Zoffix Don't we have ::= compile-time binding op specced? Is there also no way it can work? 15:13
jnthn I don't really get why you'd write BEGIN $foo := blah
Just write my constant $blah = ...
Since constants are evaluated at BEGIN time
And bind
15:14 wamba joined

Fix crashes with compile time evalution of `where` thunks

Phixes github.com/rakudo/rakudo/issues/1465
When we compile_in_context, we rake the .ann('outer')s to find all the good bits. However, the `where` thunks don't get that annotation and so the raking stops prematurely. This causes the thunk that tries to access some core symbols (like Junction ops) executed during being time explode.
Fix by adding annotating the thunk with the current pad.		 19:11

the second assignment, that is 22:10

moritz could have been my $waitfor = $promise ?? Promise.anyof(Promise.in($timeout), $promise !! $promise; 22:11
colomon moritz: was just thinking that would be clearer
but also perhaps more confusing to newbies
moritz but that's even harder to fit into one line, and i'd have to explain the ternary op
and when you only have 67 characters per line in code examples *and* use four spaced for indentation, space usage becomes a real issue in code examples 22:12
I probably should have wasted a few lines and done an if / else with two separate assignments to $waitfor 22:13

Test malformed utf8 filenames roundtripping properly

Fixes RT#127671. Please feel free to object these tests (using similar concerns raised in the ticket). However, I still can't see how something in a subdirectory of /tmp can create a problem for any user. To me it sounds like nothing should ever touch or see these files anyway.		 22:23

Whoops. New bug?

Previous commit¹ had a thinko and was attempting to treat a file created in the previous test as a directory. This is now fixed, but it seems like there's another “Malformed UTF-8” issue.
  ¹ – github.com/perl6/roast/commit/a759...15e38ee713
AlexDaniel geekosaur: sorry, what does it mean? 22:33
geekosaur I guess that might actually be aimed at Zoffix's comment 22:34
22:34 mcmillhj left
AlexDaniel ah, now I see what you mean 22:34
geekosaur on unix, you do not get to assume that filenames are utf8. or big5. or anything other than byte sequences.
AlexDaniel I think the concern was that if the test suite creates these files, then the user may later have problems getting rid of them. Yes, all the other tools that can't handle that are broken, but we shouldn't be causing this kind of trouble 22:35
so I am creating a file in a subdirectory of /tmp, this way it shouldn't be a problem for anything
unless some crazy software monitors all changes in /tmp and then explodes when files like this are created 22:36
geekosaur: speaking of broken software, this test revealed another bug in perl6 I think… 22:37
geekosaur but if it does that, *especially* in /tmp, all bets are off anyway.
pprograms can and will deliberately create weird filenames, because some programmers still think obscurity is a form of security 22:38
AlexDaniel I agree, but at the same time agree that maybe we shouldn't be testing the rest of the OS with our test suite :D
anyway, the test is now in 22:39

colomon moritz: do you know if there’s a standard idiom for sending the stdout or stderr of a Proc::Async to files? I think I can see how to do it, but it seems awfully longwinded for something I’d think would be common.
Zoffix whenever $proc.stdout { "file".IO.spurt: :append, $_ } Maybe? 23:10
AlexDaniel that's not nice 23:11
Zoffix :)
Why not?
AlexDaniel because you're slowing it down by processing the stdout in perl6 :)
there's .bind-stdout that you can call, and you give it IO::Handle
Zoffix Ahhh
