SmokeMachine This way I can pass a “join” model instead of a real model... to make it easier to join... 00:00
vrurg SmokeMachine: except that I'd expect it to be :model(MyModel)? Or do you do string resolution into a model type?
Wow, I see! That'd probably would speed up some actions. 00:01
SmokeMachine It already do the string resolution because of the lazy load... but it will accept the Model obj type as well...
vrurg My biggest disappointemnt, so far is that there is a bug in rakudo with run-away closures. It breaks so many things around. :( 00:02
SmokeMachine vrurg: yes, probably...
00:02 reportable6 joined, ChanServ sets mode: +v reportable6, kiwi_65 joined
SmokeMachine Yes... if it’s the bug I’m thinking of... I had to change a lot of stuff on Red to make it possible to remove the ‘no precompilation’ because of that... 00:03
discord6 <Aearnus> what's the syntax for coercing an argument to a type again 00:05
vrurg SmokeMachine: I think it's the one.
discord6 <Aearnus> sub f(Str(IO::Path) $s) or something like that?
vrurg Aearnus: yes, it's the syntax
SmokeMachine vrurg: I’m thinking of, on this api change, remove the red-do from experimentation and add it to core... what do you think? 00:06
vrurg SmokeMachine: why asking? My idea, your code. ;) Anybody disagree? Any one?? No? Ok! :D :D :D 00:07

scimon Is the only way to check if a Rat is going to give a divide by 0 error to check .denominator ? Is it worth adding a .safe (or some other name) method that gives False if the denominator is 0? 10:03
jnthn I think probably just checking the denominator is 0 is clear enough 10:05
scimon Yeah... I guess I would like to type less ;)
lizmat m: my $a = 42/0; dd +$a # sorta expected to see a Failure there 10:06
camelia <1/0>
scimon Ah but dd is special magic.
jnthn + is surely identity on a Rat :)
But yes, the actual division is delayed
scimon I think dd is using .perl which is fine it's the Str coercion that blows stuff up. 10:07
jnthn Right, it has to do the division then
scimon (I'm just working on the list of cool stuff to tell people about [INSERT LANGUAGE NAME HERE].
lizmat I was sorta expecting you could use prefix:<+> in combination with `with` as a quick way to see if a Rat is valid 10:08
aka, +Rat would check the denominator for you

woolfy In case people are still a bit happy that Perl 6 entered the Tiobe index at #93, be sad that Perl 6 dropped out of the top 100 already. tiobe.com/tiobe-index/ 10:27
Languages that are in the Tiobe Index on place 51-100, listed in alphabetical order: (Visual) FoxPro, 4th Dimension/4D, ABC, Alice, BBC BASIC, bc, Bourne shell, C shell, CL (OS/400), Clipper, Clojure, CoffeeScript, Common Lisp, Crystal, cT, Erlang, Euphoria, Factor, Forth, Icon, Inform, Io, J, Korn shell, LabVIEW, Ladder Logic, LiveCode, Maple, Mercury, ML, Monkey, MQL4, MS-DOS batch, NATURAL, OpenCL, OpenEdge ABL, Oz, PL/I, Ring 10:29
tadzik given how obscure these are, I can't believe Perl 6 is not more popular than this, whatever your measure of popularity might be 10:30
make it seems like TIOBE is just not very good at distinguishing Perl and Perl 6
we'll see when Raku comes around... ;)
woolfy tadzik: any article that Google can find should have "Perl 6 programming" in it: tiobe.com/tiobe-index/programming-...efinition/ 10:31
tadzik: I think most people only write "Perl 6", "Perl6", "Rakudo Perl 6", and therefore any news about Perl 6 will not be picked up by Tiobe. 10:32
10:32 squashable6 joined
tadzik woolfy: yeah, I'm not a big fan of their methodology either :) 10:35
10:38 ravenous_ joined, Black_Ribbon left
woolfy tadzik : it is not very important to be a big fan of Tiobe or not. It seems that quite a lot of people use it as a means to qualify or disqualify a programming language for their new projects. To have a programming language acceptable to be used inside their company. 10:39
It's a bit like people who do not believe in gravity: jump of a building and you will fall down, gravity doesn't care if you are a fan or not. ;-)

scimon The "We won't use language X because it's not popular" circular argument is a thing. Unfortunately most businesses exist to make money and not train developers (or let devs do what they like). 10:54
So you get the vicious circle. No one pays people to write X so no one learns X because they can't get a job in it... sigh. 10:55
Critical mass is the thing (and why having a niche and / or a killer app is important). 10:56
Remember when everyone suddenly wanted to learn Ruby because Rails was a thing? (And then they killed it with their constant updates).
tadzik woolfy: you are correct :) 10:57
woolfy scimon and tadzik : it still makes me sad when stuff like this is correct...
I remember happily the time (I think it was the YAPC::Europe in Frankfurt) when we were sitting with a large group on the terrace in front of a restaurant, when masak arrived with the words "I found Perl 6 modules on darkpan" and we all rejoiced. 10:59
(or something like that)
tadzik well, to get back to the gravity example: it doesn't matter if we like it or agree with it, it's the best model of reality that we currently have, and the best we can do is work with that :)

lizmat Whether you agree with this or not, a TIOBE listing means bankability of a language 11:55
we need bankability for Perl 6, because without it there will not be any commitment from companies using the language
woolfy -> Whether you agree with it or not, gravity means stuff falls down to Earth. 11:56
lizmat and without commitment from companies, there will not be any jobs
in Perl 6
nor will there be any money for grants

Ulti yeah I would say perceived popularity is kind of more important in open source, its how you get adoption because people will try out the language and related libraries at home and then introduce their place of work to it when they see a fit 13:04
going straight for corporate adoption feels a little strained, how can you actually target that without a lot of investment in solving specific problems for them and putting it in the core language? 13:05
and by investment I mean actual monetary investment and understanding of what problem space you'd take the language as a whole down... at that point it becomes more of a DSL for a task too 13:06

AlexDaniel so what I have is this github.com/perl6/whateverable/blob...ble.p6#L74 15:25
basically, the idea behind that line is that if you .tell to somebody and they reply immediately, the message won't be delivered
and you can see that in action here: colabti.org/irclogger/irclogger_lo...08-20#l116
so it works, right?

15:26 pamplemousse joined
AlexDaniel my current hypothesis is that something in the for loop throws, so it ends up jumping out of that sub altogether 15:28
I'm not seeing any exception anywhere, so that's weird, but maybe maybe
now, after 10 minutes it no longer throws, so it ends up delivering the messages ( github.com/perl6/whateverable/blob...ble.p6#L30 ) 15:29

irced hey all, is it possible to declare a class method then define it elsewhere outside of the class definition itself (e.g. in another file)? directly or maybe by reference? (i realize i could create a subroutine and pass a reference to the object maybe even assign a variable in the class definition to name it but is there a less indirect way? 16:41

[Coke] tbrowder: if you dd %P5::h before you try to use it, you'll see it's not initialized. 21:01
so you're doing my %foo = Any; # basically
tbrowder ok, is there a way at all to access the hash from p6? 21:02
i have in the past just rewritten the p5 module to p6 and that worked. and i have just been using p5 modules successfully (objects and funcs only thus far), so i was hoping to use p5 vars. 21:04
maybe make them p5 constants (which they are)? 21:05
[Coke] Dunno yet, digging. This works: gist.github.com/coke/55bdb09c953c8...ee0ba5d993 , so it seems theoretically possible.

irced hey all, so i'm wrapping my head around concurrency and dabbling in the event driven paradigm, that said, given that i can react to a Supplier with a whenever block and that the whenever block assign $_ the value emitted, how would i go about a conjunction such as whenever $supply1 && $supply2 and examine their individual emissions ? 22:15
i tried .tap inside the whenever block but no dice (it seemeth) 22:17
[Coke] if it's event driven, you're saying you want to wait until you have an event from both? 22:18
irced Coke: exactomondo!
rba marketing.perl6.org/ is back online, yayh. 22:19

woolfy1 rba++
[Coke] if you have something going every 3 seconds and something going every 10s, what behavior are you looking for? 22:24
woolfy1: long time no see.
hi
irced the supplies are not intervals, and I am using them more like channels. 22:25
22:33 rindolf left
irced i have two domains that emit values and a third domain (that i call payload) will collect those values then emit itself (the payload). this is not based on any model i've seen in existence mind you. but I think I am still within the paradigm. 22:33
it emits its "self" to yet another domain. but anyway, i think this explains what behavior i'm looking for in the least. 22:34
22:35 pmurias joined
[Coke] if the elements are paired, does it make sense to have something that emits a tuple instead? 22:35
irced the whole emits to another domain is accomplished by each domain having the supply or channel that it expects emissions from
no matter what "self" i emit, the fact is, i need to be sure two domains have provided the values to fill the pair/tuple 22:36
[Coke] (my interval question was trying to get at the root of that, what do you expect to happen if the events are not coming out at the same time)
irced i want to wait (non-blocking) and react only when both independent events have been triggered 22:37
regardless of which finished first and whether is was "simultaneous" (no synchronization idea involved here)
well loosely involved i guess 22:38
so it seems safe to use $supply1 && $supply2 this this reaction will only be true once the supplies have something to emit, and this happens only once in the lifecycle. 22:40
anyway, the problem with whenever $supply1 && $supply2 is i don't know how to get the emissions individually 22:41
i suppose i could chain reactions, seems lengthy but not nonsensical 22:42
using the topical variable in two blocks (one nested). 22:43
but it seems although tmtowtdi, some ways seem "too" long 😃anyway, trying that now
hmm, probably don't need to "start" nested, can block inside i think 22:54
jnthn irced: Maybe you want Supply.zip($supply1, $supply2) 22:57

irced hey all, i am passing a supplier to different classes after initializing it with Supplier.new, however, they don't all seem to see the same supplier. specifically, one sees Supplier.new and the other one sees Supplier[handleid...] is there an accepted way to ensure an empty supplier is the same wherever it is passed as an argument ? 23:52
basically, what is the correct way to pass suppliers unto other functions after they are initialized with $supply = Supplier.new 23:55
so that things don't break
😃 23:56
i mean, as soon as i do $supply = Supplier.new i get something like Supplier<94524891953648> but i pass it unto other functions and one of them for some weird reason sees Supplier.new 23:57
err, actually on another thread i start supplying and then it gets an id, just not in sequence so scrath that last statement 23:59
nevertheless, another function, which has been passed the supplier by name, never picks up on the id assignment
