atroxaper I'm trying to understand a Container system deeply. I'm reading docs and the code of MoarVM, nqp and Rakudo. And I have a few questions. 1) As I see in the code, there is the only one 'container' - Scalar. Only Scalar has specific 'container specification' (and Proxy also). But (my @a).VAR.^name says Array. Why? 2) I cannot find VAR method code. Probably its implementation will help me to answer the first question. Where is it? 3) I cannot 08:11
find decont operator (<>) code. Docs says it is postcircumfix:<>. As I understand, <> is implemented only on Grammar/Action layer but I cannot find it. And why is it postcircumfix instead of postfix? :)

Voldenet atroxaper: if you see the output of –target=ast, usage of <> uses { } if i'm interpreting this correctly: `QAST::Op(call &postcircumfix:<{ }>) <wanted> <>` 10:02
erm, --target=ast
atroxaper Voldenet: I did so. That is why I decided that <> implements on Grammar/Action layer. 10:09
Voldenet: But now I try to decont by {} and it is works as <> promises :) Probably it is 'specific Rakudo implementation'. 10:12
jnthn Isn't it just a default case of the zen slice on a non-aggregate? 10:14
This is the impl that leads to the decont: github.com/rakudo/rakudo/blob/mast...e.pm6#L171 10:15
atroxaper jnthn: Actually, I'm right now found it myself ^^ 10:16
Yes, it is zen slice. 10:19
jnthn About .VAR, all it does is wrap it in another level of Scalar container, such that a method call on it will decont the throwaway container.
However, if you pass it through two things that both want to discard a container, then it will unravel. Really, the only thing you can safely do with the result of .VAR is call a method directly on it. Or bind it such that you can call multiple ones. 10:20
atroxaper jnthn: pretty deftly
I think, question #1 is hardest 10:22
jnthn: Well... If .VAR just wrap to one more container, then (my @a).VAR === Array means that Array may be not a container. 10:24
10:25 a3r0 left, a3r0 joined
jnthn atroxaper: .VAR is a no-op in that case 10:26
atroxaper: It only does it if nqp::iscont returns true 10:27
(where "it" is the wrapping)
atroxaper jnthn: I'm I right that only Scalar is a 'container', but not an Array or Hash or Callable? Is it Rakudo specific implementation?
10:30 pmurias left 10:31 lichtkind left
tbrowder guifa: if bill and i can help in houston (or ahead of time) we're happy to assist you 10:36
jnthn atroxaper: Only Scalar and Proxy 10:37
atroxaper: That .VAR is a no-op on anything exept these is spec
atroxaper: As is the existence of Scalar and Proxy
atroxaper jnthn: Now I check nqp::iscont(Array) == 0; I just want to know, is it part or specification (roast) or Rakudo implementation only. Because documentation describes "callable containers" for example. 10:38
jnthn atroxaper: How exactly an implementation chooses to achieve that (e.g. Rakudo's container_spec mechanism) is implementation defined. There's also no official way to add additional kinds of containers either.
nqp::iscont is - like all nqp::foo - Rakudo specific, but its semantics are such that it gives 0 whenever .VAR is identity 10:39
And .VAR doing that on Array is spec
(that is, returning identity) 10:40
atroxaper jnthn: Many thanks! Now I understand much more then previously :) Some advents and documentations about 'containers' a little confused me and I decided to find out everything directly from their code. 10:42
jnthn Yes, I think "container" gets used to mean quite a broad range of things, but only Proxy and Scalar are kinds of "item container" 10:45

lizmat sometimes I wonder why o why people want to re-invent the wheel: blogs.perl.org/users/lichtkind/2020...-kbos.html 12:24
12:25 atroxaper joined
tadzik maybe one day we'll end up with a round one... ;) 12:25
El_Che round is overrated
it's clear that Perl needs an extra OO framework 12:27
pmurias lizmat: fun?
lizmat I guess 12:29
El_Che " class types (not even Raku has them) "
isn't class type just a class? 12:30
I am missing something probably
lizmat I guess they mean that you could have a group of class sharing a type
El_Che a class like a struct? 12:31
lizmat m: role GroupType { }; class A does GroupType { }; class B does GroupType { }; dd A ~~ GroupType; dd B ~~ GroupType
camelia Bool::True
Bool::True
lizmat voila, in my interpretation, those are "class types"
it feels the same as Positional or Associative classes, reallt 12:32
*really
alas, I've given up trying to comment on blogs.perl.org
pmurias lizmat: is there an explanation of what he means by "class types"? 12:34
lizmat not that I could further gather from the blog post
pmurias OTOHhe has a next blog post planned on that topic 12:35
El_Che my definition of overengineering your app: creating an adhoc OO/ORM/Auth/etc system only for your app :) 12:37
but on the other hand, maybe that's how generic libs are born :)
tyil using `dd %?RESOURCES<foo>.DEFINITE` in a module gives me a warning "Use of uninitialized value %result{'resources/foo'} of type Any in string context.", but still shows `Bool::True` as the result of the `dd`. There's no 'foo' resource in the module 12:38
is it intended that a missing resource is still considered definite, while also showing a warning about it?
(I'm looking for a way to check in my module if the resource actually exists) 12:39
lizmat what does dd %?RESOURCES<foo>:exists give ?
12:39 hungrydonkey joined
tyil Bool::False, but it seems to do that for existing resources as well 12:40
(that was one of the first things I tried, since it seemed the most obvious) 12:41
lizmat maybe the AT-KEY implementation on %?RESOURCES is borked
12:42 hungryd7 left
tyil github.com/rakudo/rakudo/blob/add2...n.pm6#L223 12:43
seems to always return a Distribution::Resource, not sure if those have (correct) boolean representations
lizmat hmm... interesting, implementation appears "incomplete" I'dsay 12:45
tyil no method Bool() at least, and IO() always returns something as well
lizmat would have to dive into that (having meant to do so for a while) 12:46
but my head is full of other stuff at the moment, so that would be a hard context switch :-( 12:47
12:47 mowcat left
lizmat I wonder though why Distribution::Resource doesn't just have an .IO instance of itself, and then use "handles" for all the methods it appears to support 12:48
tyil I would have no clue on that either :p
using .IO on a non-existing resource also shows the warning, but does return an IO::Path pointing towards the /usr/share/perl6/site/resources directory 12:50

atroxaper One more question about containers and binding... Why binding into $ and sigilless is different? Example: 13:18
my @a; @a = (1, 2) #uses Array.STORE
my \a = []; a = (1,2) # uses Array.STORE
my $a := []; $a = (1,2) # fail 13:19
my $a :=[]; $a<> = (1,2) # uses Array.STORE
jnthn 'cus the compiler case-analyzes based on sigil 13:20
And in the case there's no sigil, has to do a late-bound thing (e.g. nqp::iscont(x) ?? nqp::assign(x, y) !! x.STORE(y)) 13:21
In principle it could always do the latter, but then every assignment would code-gen into something ~5 times the bytecode size. 13:22
atroxaper jnthn: Thanks! 13:25
patrickb rba: Whenever you have time: I have made another change to the rakubrew.org website (fixing installation on Powershell). You can deploy whenever you have time. 13:29

patrickb: The fix is in the image or in the data? 13:40
patrickb only in the website repo at the moment. 13:42
There is no now rakubrew version. Only the website changed
tadzik: Once rakubrew is out of the testing phase, we'll have to decide whether rakudobrew will live on or will be deprecated. I'll leave that decision to you. 13:43

jnthn Skarsnik: Make sure that you have an SDK set up properly (under File > Project Structure) 13:57
rba patrickb: updated, may you double-check, please?
patrickb rba: Looks good! 13:58
Skarsnik ohh thanks, I moved file round because it did not put the file in the folder I wanted, that probably why it lost the sdk setting x)
still does not work. also it could be nice to be able to run zef from Comma (too lazy to try to run it under windows xD) 14:00

Skarsnik I mean, I try to run something and it should probably shows what it try to do? like 'raku myfiletorun.raku' error blablalba 14:33
sena_kun Skarsnik: the script is placed in jar resources, so you firstly have to obtain it. 14:34

sena_kun Skarsnik: sorry, I mean Comma release 2019.12. 14:45
Skarsnik Hooo
Do you have a link to this version so I can try? I don't find a link to older releases x) 14:47
libertas hi, would like to try raku-debug with this line: $ raku-debug -e "'foobar' ~~ /f.+b/;" 14:48

Could not find Debugger::UI::CommandLine in:
do I have to install some CommandLine package? 14:49
rypervenche libertas: You need to zef install Debugger::UI::CommandLine
If you don't have zef installed already, you can get it here: github.com/ugexe/zef 14:50

rypervenche libertas: Can you pastebin the errors for us?
Skarsnik I am just trying comma, I don't have a sub then ^^ 14:52
libertas rypervenche: I'll delete zef, reinstall it, and do as you suggest 14:53
rypervenche libertas: You have zef already, you shouldn't need to reinstall it. Can you show the errors you're seeing?
libertas is zef meant to be run under root, right? 14:56
rypervenche I believe it can be run as either a user or as root. I do it as a user so all of my modules get installed into ~/.raku . 14:57
libertas ok 14:58
I did the reinstall again and it failed as can be seen at pastebin.com/E3JaFWuw
sena_kun Skarsnik: only latest community releases are served, so nope. you can either wait for a hotfix release at the end of the month if there will be one or move to a linux box.

sena_kun Skarsnik: what do you mean with "syntax check"? 15:01
or, well, I know what you mean, but Comma doesn't use `raku -c` or something like that to check syntax.
Skarsnik it's just an issue with symbols from other modules or something? 15:02
sena_kun Skarsnik: seems like it. I'll patch it next release, possibly we'll do a community hotfix.
rypervenche libertas: Yes, you already have zef, so no need to try to reinstall it. Try simply running: zef install Debugger::UI::CommandLine 15:03
[Coke] . 15:04
Skarsnik hm, it does find await too, is that supposed to be a language keyword? x)
*does not

libertas rakudo was via the package manager, zef as git clone github.com/ugexe/zef 15:08
rypervenche What does "raku -v" output?
tadzik git clone will not be enough to install it 15:09
libertas rypervenche: This is Rakudo version 2020.01 built on MoarVM version 2020.01.1
implementing Perl 6.d.
tadzik unless you followed it up with the install step as the readme says :)
but then you shouldn't need to run it with ./zef
libertas tadzik: but it generates an error 15:10
runnit with ./zef because it's not im my PATH yet

lizmat yeah, that's my interpretation of that
Altreus has $.delayed handles <list> = slack { something I've yet to invent }; ? 17:49
lizmat Altreus: yeah, that sounds about right ? 17:50
Altreus I'll play around :) thank you lizmat ! 17:51

rypervenche libertas: It looks as though the Void package may be broken. A fresh install can't find NativeCall. 17:57
Altreus can the slack property access the other properties? Does the block know about the owner object? 17:59
libertas ah, glad you found the issue
Skarsnik I am always confused, why calling .mymethod in a method does not work when self.mymethod work? 18:00

Cannot resolve caller AUTOGEN(Usb2Snes:D: Usb2Snes-Opcode:D, List:D); none of these signatures match:

tbrowder hi, all 18:49
rafaschi heya
tbrowder i just noticed raku doesn't have trig functions with degree versions 18:50
lucs In my Foo.pm6, I print $?FILE and obtain something like "/path/to/Foo.pm6 (Foo)". 18:51
What's that trailing " (Foo)" doing there?
tbrowder any objections to adding them?
atroxaper Skarsnik: self.send-command($cmd, (my Str @ = $arg)); # looks better? 18:52
sena_kun lucs: module name
lucs Sure, but why?
tbrowder e.g.: sind cosd tand atand atan2d etc
sena_kun lurcs: hmm, is "why" to my answer or? 18:53
lucs I want the file name, not its description or whatever.
sena_kun lucs: you can just trim it
lizmat m: dd $?FILE 18:54
camelia "<tmp>"
tbrowder my answer is 1. because we can and 2. i want to use the repl as a pocket caculator
lucs sena_kun: That is seriously LTA.
lizmat m: say $?FILE
camelia <tmp>
lucs lizmat: Yeah, I tried that with camelia here, saw the same results. 18:55
lizmat $ raku 1
"/Users/liz/Github/rakudo.moar/1"
$ cat 1
dd $?FILE;
ah, precomped? 18:56
sena_kun lizmat: you need file to be in a module-like compunit
not a temp or a script
lucs Oh, yes, it is precomped I guess.
atroxaper tbrowder: probably, it is good to stay a core of compiler not too large if possible. Any additional math functions maybe implemented in modules.
lizmat lucs: confirmed... wonder where that comes from 18:57
sena_kun dunno, I think it is handy, sometimes you want to know the module a thing is from. we are using it in Comma, for example. maybe $?FILE is not the most obvious name compared to e.g. $?FILEINFO (which can hold more things?), but hmm
lizmat I'd say that *is* LTA
lucs sena_kun: The handiness is nice, but it should be implemented somehow else :) 18:58
lizmat "Which file am I in?"
18:58 sauvin left
lizmat so, you could argue it is wrong in more than one way 18:58
a. it's a Str, not an IO::Path
b. it's not an .IOable string
lucs: could you make an issue for that ? 18:59
lucs OK
Thanks for confirming
18:59 jmerelo left
sena_kun NOOOOOOOOOOOO 18:59
github is at it again... 19:00
tbrowder atroxaper: but we already have many core math routines and the degree versions are probably used more by non-mathematicians
19:03 Black_Ribbon joined
rafaschi I don't think new functions would be the best approach, but a new numeric type that can do clock arithmetic would be nice. If it knew how to convert itself to radians, the trig functions could accept it. 19:03
sena_kun wouldn't one want to write a module for it? 19:04
rafaschi At least at first, I think it should be a module.
atroxaper tbrowder: we already have the to-json sub but want to remove it from the core. All thing in the core have to be documented and covered by tests (spec). There are a lot of unobvious tasks for each new thing. For example, a good subs' naming. 19:05
sena_kun IIRC, the current policy is "make it a module at first" and then "if there are serious reasons to do so, pull into core".
tbrowder maybe there is one already...
there is Math::Trig but no decimal trig functions 19:09

sena_kun tbrowder: I think you can just fork, update maintainence notices if any and update ecosystem versions with yours 19:26
tbrowder it's the perfect one for adding decimal trig functions
moritz yes, just take over his module for maintenance / enhancements 19:27

"instantiated"
lizmat Altreus: ^^
Altreus Then it doesn't like that combined with ::?CLASS
Cos it worked when I renamed one of the options
hmm 21:48
It works when I *remove* one of the options
i.e. leave one in, but still multi
21:49 sena_kun joined
Altreus right 21:49
21:52 dustinm` left
Altreus I have isolated it to: A multi method, differentiated by definedness of invocant, in a Role, using ::?CLASS instead of a known class name, where *one of the multis is unimplemented* 21:54
So, nice and simple
21:54 rindolf left
Altreus The idea being that whatever consumes it gets one method with a default implementation on a type object, but has to implement the instance version 21:55
Should I expect it to work? :)
lizmat gist ?
Altreus except ... I can't get it to break 21:56
ohhh it's the return type!
Now I can gisy 21:57
t
here :) gist.github.com/Altreus/528c6172a6...a3ace22b19
without « returns ::?CLASS » it seems fine
lizmat nine: grrrr "repeat while $?FILE.ends-with($caller.file) { 21:58
Altreus I can't put « returns ::?CLASS » on an unimplemented multi method which also uses ::?CLASS to define the invocant 22:00
so those four things together cause this error, and it seems like any combination of fewer than those four things is fine 22:01
I guess I'll open a raku issue :D
tyil guifa: even for nonexistend files, %?RESOURCES returns the base dir of the repo's resources dir, which is true when called .IO.e on it 22:03
though it *also* shows a warning for me
guifa aaah maybe that’s what I was doing and catching the warning
(it’s been a while since I worked with the Fluent module that had the same issue) 22:04
tyil for my current module, I'm only working with files, so I can .IO.f for now
