stoned75 what was the reason for github.com/rakudo/rakudo/commit/42...bb0bed2fb9 ? 00:10
lizmat stoned75: because, just as Lists, Maps can have containers as values, and are thus potentially mutable, and thus not value objects 00:12
stoned75: see also: github.com/rakudo/rakudo/pull/3331 00:13
stoned75 ok. I see. obvious ! thanks !

kawaii Hello, I'm trying to use the YAMLish module to turn the contents of this document (github.com/mybb/mybb.com/blob/gh-p...mbers.yml) into a hash, using the `username` attribute as the key but using the `load-yaml` method only ever gives me one large item, any ideas? It strikes me that YAML seems difficult to parse compared to JSON 02:02

kawaii: Looking... one sec. 02:16
kawaii Xliff: thanks, appreciate it :) 02:18
Xliff kawaii: Are you using YAML or YAML::Parse?
kawaii Xliff: github.com/Leont/yamlish
YAMLish
If there's another module I'm happy to try :)
02:21 seanrobert left
Xliff kawaii: OK. What comes out is an array of hash objects 02:22
You will need to further process it if you want it to be a hash,
my $o = load-yaml("test.yml".IO.slurp); my %h = (gather for $o[] { take Pair.new(.<username>, $_); }).Hash 02:24
kawaii Xliff: ahhh I see my mistake, I was doing load-yaml directly into a hash object 02:26
thank you so much, this is perfect
Xliff You're welcome!

camelia False
vrurg Hm...
m: my $*ADYNAMIC = pi; say DYNAMIC::<$*ADYNAMIC>:exists; 03:22
camelia True
guifa2 ah duh, I always forget about that adverb
Although I think CALLER could be better than DYNAMIC 03:24
If you declare the variable in the same scope, but later somehow, it seems to still give you true 03:25
actually no, CALLERS still gives true, at least in REPL 03:26
03:26 Xliff left
vrurg guifa2: callers would give you not only dynamics, if memory serves me right. 03:28

from gen/moar/ModuleLoader.nqp:254 (/home/camelia/rakudo-m-inst-1/share/perl6/lib/…
vrurg Ok, 6.c/6.d do have some problems which are going to be there for backward compat. But 6.e must be different. 03:32
Sorry, my bad. The difference between DYNAMIC and CALLERS is the former also lookups in the current scope whereas CALLERS starts with the caller scope. 03:35
guifa2 vrurg: yeah, that's why I was thinking CALLERS might be better because UNIT includes post-declared variables 03:41
and I can imagine in a recursive routine, someone doing if CALLERS::<$*foo>:exists { do one thing } else { my $*foo = 5; callsame } or something like that 03:42
guifa2 actually did basically exactly that with one of his modules
I guess in that case the else block is separate, but the declaration could happen separately somewhere in the same scope 03:43

MasterDuke your `$f.grep` is trying to do a list operation on a string 09:10
you probably want `$f.contains` 09:11
09:11 JRaspass joined
notagoodidea I certainly want it now :) 09:11
thanks
MasterDuke np
notandinus MasterDuke: notagoodidea: thanks, 09:16
how do i get "where" part for this param? &MAIN.signature.params[0] 09:20
Str $action where * ∈ <backup rotate>
^ it's defined like this, .params[0] is $action, i need <backup rotate> part from it 09:21
so that i don't have to define it twice, i'm going to define my own USAGE
jmerelo notandinus: not sure it's accessible. It might be, though...
notandinus when i print &MAIN.signature.params[0], it does say 09:22
MasterDuke create a subset first and use it in both?
notandinus Str $action where { ... }
MasterDuke: i see, i'll check that
jmerelo notandinus: um, that would be a Parameter type, and it does have a .constraints method. docs.raku.org/type/Parameter Give it a try. It might be .signature.params[0].constraints 09:23
09:24 aluaces joined
notandinus jmerelo: all(WhateverCode.new) 09:25
MasterDuke i think it comes from github.com/rakudo/rakudo/blob/mast...n.pm6#L208
notandinus that returns ^
i'm trying the subset thing
notagoodidea notandinus: from there bduggan.github.io/meta-perl6-cli/#38 and the fact that `MAIN("alice")` is behind the hood `MAIN(Str $foo where {$foo eqv "alice"}` 09:26
jmerelo notandinus: right, it's not terribly helpful... Mainly you can't extract individual elements out of a Junction, I think. Introspection can only take you so far... 09:27
notandinus notagoodidea: ah i forgot that, thanks 09:28
yeah it's a junction thingy 09:29
i've defined a subset like this: subset Action of Str where * ∈ <backup rotate>;
notagoodidea Don't you will have the same issue to access the value of the Junction there ? 09:30
notandinus oh wait, i could just define an array @actions now and put <backup rotate> in it,
notagoodidea: yeah not a good idea ;)
notagoodidea notandinus: That's what I have done when I played with it.
`my @sub = <foo bar> ; ... MAIN(Str $sub where { * eqv any @sub });` 09:31
notandinus wait then i don't have to bother with subset
notagoodidea But maybe an enum is better there ?
notandinus yeah i'lll just do where * ∈ @actions
notagoodidea: i don't know what an enum is , i'll check it out 09:32
notagoodidea I was just looking at it yesterday so, pinch of salt because I am not sure to have a full grasp of the enums in Raku
notandinus hmmi also need to have description for each action, i'll make it a hash for now 09:35
hmm the enum thing is working fine 09:41
using a subset will work the same way right?
09:41 Altai-man joined
notandinus or even a constant @array 09:42
09:44 sena_kun left
notagoodidea notandinus: for the MAIN part yes. With a subset you will call it `MAIN(Action $str, ..)` 09:46
I just don't know if it convinient for the USAGE after, or just harcode it somewhere. 09:47
09:47 aborazmeh left
notandinus notagoodidea: enum looks good, i made it an enum 09:48
enum Actions ( backup => "make a backup) 09:49
^ this way i can just use the hash directly to print usage
and restrict it too
notagoodidea Is there a profiler for raku? 10:01
notandinus yeah, just run --profile 10:02
10:04 brtastic joined
notandinus ok so i need a --version flag 10:15
$action needs to be passed all the time except when --version is passed, how do i define this? 10:16
i can make a multi MAIN, is that the best way?
notagoodidea maybe you will have to make $action optional, I am not sure how the multi sub dispatch with positional parameters & flags? 10:24
notandinus: I remember, multi sub yes but you will need to have a general case MAIN to call USAGE when to params are passed or it will dispatch on the sub with the version flag (or the last flag). 10:33
or not. 10:34
notandinus notagoodidea: i've defined it like: multi sub (Bool :$version) {} multi sub (Action $action,... ) {} 10:36
and it seems to work fine
i added is-hidden-from-USAGE in first multi and added a :$version to second multi too so that it comes up in usage
when --version is passed, first multi gets called, 2nd one is all other cases. 10:37
notagoodidea mm, notandinus this minimal version always dispatch on :$version sub (outputing "ALPHA") when called without parameters : pastebin.com/S0N4QzgF 10:45
but I don't know why. 10:47
kawaii Does Raku have some built-in way to check the age of a variable or when it was last written to/updated? 10:50
MasterDuke dispatching with named variables can be a little tricky, recommend reading docs.raku.org/language/functions#i...i-dispatch 10:51
notandinus notagoodidea: hmm yeah , no t sure why
MasterDuke kawaii: no, but istr someone wrote a module to do something similar
samebchase- kawaii: no, you'll need to define your own object which keeps tracks of updates or use a module as MasterDuke suggested 10:52
kawaii Okie, thanks :)
notandinus mine is : paste.debian.net/hidden/59ff407b/
and it dispatches on second multi in all cases except when --version is passed
11:04 linkable6 left, evalable6 left 11:06 evalable6 joined, linkable6 joined 11:10 Black_Ribbon left
notagoodidea notandinus: Does yours call USAGE on empty parameters ? 11:12
11:13 moony joined
notagoodidea MasterDuke: For what I see, because named argument prevails on arity, the dispatch will always go to the named argument. 11:14
So for MAIN, it is a bit weird because it will output the first flag it will dispatch against. 11:18
11:23 sjm_uk left
notagoodidea mm, it is not that weird in fact if one want to reproduce a command like `ls` but to mimic `git` and call the help when no parameters provided, we must use a catch-all flag at the beginning of the multi-dispatch to call USAGE. 11:24
notandinus notagoodidea: yeah it calls USAGE on empty params 11:33
notagoodidea: oh wait 11:36
it doesnt
i dunno why i was saying it does, so i'll have to add an empty multi MAIN? 11:37
11:45 asymptotically left
notagoodidea notandinus: That will not work like in my example. If I understand multi dispatch correctly, named argument seems to prevails. A solution seems to be to put a named argument on top of all and made him call USAGE like 'multi sub MAIN(Bool :$help-implied) { say $*USAGE }` before the multi calling version for you. 11:48
11:50 asymptotically joined, jmchael joined
notandinus notagoodidea: i see, thanks. that works fine, one could also do `$version ?? say "Leo v0.6.0" !! USAGE();` right? 11:51

tech_hutch So I was trying out the REPL, and things seemed a little odd 15:31
tbrowder yo, all, anyone else having trouble with github workflow tests?
perry [Coke] you could always do U+1F964
tbrowder for their modules?
tech_hutch It says `Welcome to 𝐑𝐚𝐤𝐮𝐝𝐨™ v2020.12.` Is that just my terminal encoding being set wrong?
perry tech_hutch: ha. probably. 15:32
tech_hutch Like, is it trying to say Raku in Japanese or something? lol
perry tech_hutch: here's what it looks like for me: i.imghurr.com/e/MDUrObsPHx.png
tbrowder i'm getting "operation cancelled" when zef is searching for dependencies 15:33
tech_hutch Ohhh okay. So it's using some odd Unicode chars
perry It's UTF-8. Mathematical bold letters.
tech_hutch `~` is the string concatenation operator, right? and so `~=` would concatenate and reassign? 15:35
I'm getting some strange results. Sometimes when I do, e.g., `my $thing = "hi"` `$thing ~= " there"`, subsequently doing `$thing` prints "hi there there", "hi there there there", etc. 15:37
Is this just a repl bug?
perry tech_hutch: not sure what you mean. This is what I see: i.imghurr.com/e/mZMDMTPDbl.png 15:38
15:39 parabolize joined
tech_hutch Sometimes that happens for me (which is what I'd expect), but other times I get the weird behavior I just described 15:39

perry Huh. I don't either. 15:41
tech_hutch Here's an image I uploaded to Discord yesterday (I think you can see it without an account): media.discordapp.net/attachments/2...nknown.png
perry Huh. That's interesting. 15:42
Tirifto tech_hutch, perry: Here’s the output of mine: zerobin.net/?dc0bb01b57eb7c7d#DQYg...PyUc3oI8Q=
perry Doing the exact same thing Tirifto, I get different output 15:43
notagoodidea it doe not incremet "there" on mine.
perry notagoodidea: that's cause you're cool like me 15:44
Tirifto, is this also in Powershell?
notagoodidea <3
tech_hutch It's not doing it for me now
Tirifto :P
notagoodidea Here it's rakudo 2020.02 / 6.d on Fedora with fish.
tech_hutch The cool kids don't experience repl bugs 😎
perry notagoodidea, same here but macOS 15:45
and also Fish :)
tech_hutch Mine is PowerShell through Windows Terminal
notagoodidea perry: indeed like you :D
perry tech_hutch, can you reproduce it with either 1) the text Tirifto sent or 2) in a different terminal emulator?
Tirifto I’m running Rakudo 2020.12 in Bash on Parabola GNU/Linux-libre (derived from Archlinux), installed with the help of AUR (a community package repository).
perry This bug has nerd-sniped me I think 15:46
Oh wow that's weird
Tirifto Oh wait.
perry Oh my Rakudo might be out of date then. Just realized I'm on 0.10. 15:47
2020.10*
Tirifto I may actually be running a non-release version.
perry gasps
Tirifto I do recall installing 2020.12 and finding it oddly slow to start, so I tried installing the version from master, and I might be running that now… but that said, 2020.12 did feel kind of weird right from the start. 15:48
tech_hutch perry yes, exactly the same output for me 15:49
perry waaaaaat
tech_hutch cdn.discordapp.com/attachments/250...nknown.png
Tirifto tech_hutch: Did you install the ordinary Rakudo 2020.12 release version? 15:50
MasterDuke the repl has always been a bit odd and had bugs unique to itself. lizmat++ made some changes recently, so there might be new behavior 15:53
15:53 abraxxa1 left 15:54 [Coke] joined, [Coke] left, [Coke] joined
lizmat yes, the REPL has new quirks :-) 15:55
tech_hutch Tirifto yeah, from here rakudo.org/downloads
perry "surprise features"
[Coke] oof, that was weird. on mac. jostled something, got an alert that the external drive with everyone's home dirs on it needs to be shut down before you unplug it. it was still connected, but my Dock preferences were all reset. weird. 15:56
tech_hutch I just worry bugs like this would confuse a newcomer (like me) even more 15:57
Tirifto I can confirm that ‘hi there’ works as expected in a script.
tech_hutch That's good, at least
MasterDuke i just checked and that odd behavior doesn't happen on 2020.08 15:58
tech_hutch Also, you know what would be cool? A place online where you can try out Raku without downloading anything, like a lot of other languages have
(unless there is one and I missed it)
15:59 guifa2 left
[Coke] there is. one sec. 15:59
tyil glot.io has Raku support, no?
MasterDuke m: say "hi"
camelia hi
15:59 guifa2 joined
tyil tech_hutch: glot.io/new/raku 15:59
MasterDuke also run.tio (or tio.run, can never remember the order)
tyil tio.run iirc
don't think .tio is a valid tld (yet) 16:00
tech_hutch ah cool. the site should link there
[Coke] (one sec until others fill in the URL, thanks. :) 16:01
Tirifto p6: my $thing = “hi”; $thing ~= “ there”; say $thing; say $thing; $thing ~= “ there”; say $thing; say $thing;
camelia hi there
hi there
hi there there
hi there there
Tirifto The evalbot is safe. :-)
MasterDuke those are linked from raku.org/resources/
guifa2 Is there any way to substr a str and get a str back (that is, avoiding boxing)? 16:02
tech_hutch MasterDuke ah ok. Still would be nice to link it more prominently. E.g., Go has one embedded right in the homepage 16:03
MasterDuke i think there is a doc issue about similar ideas (e.g., make the examples in the docs runnable/editable) 16:04
github.com/Raku/doc/issues/1866 16:07
El_Che tio is uncle in spanish 16:08

MasterDuke guifa2: maybe if you nqp ops directly 16:11
*use 16:12
guifa2 MasterDuke: I was afraid that'd be the answer lol. Trying to avoid nqp
MasterDuke fwiw, Strs and strs are pretty similar, not like int and Int 16:13
why don't you want the boxing?
16:14 aborazmeh left, Doc_Holliwood left
[Coke] Is there interest in having a sort algorithm like tcl's [lsort -dictionary]? ("in -dictionary mode, bigBoy sorts between bigbang and bigboy, and x10y sorts between x9y and x11y.") 16:15
could do it as a sub for folks to pass to .sort... 16:16
tech_hutch oh, so this language has autoboxing?
MasterDuke tech_hutch: yep 16:18
16:18 mowcat joined
guifa2 Masterduke: I know the boxing and unboxing are extra ops that I'd like to avoid — I'm doing an sprintf-like operation, and I'm playing around with different things to keep it is nimble as possible. Using native ints can be a massive speed up, so I was hoping I might get similar out of strs 16:18
MasterDuke m: my int $a = 4; say $a.WHAT
camelia (Int)
MasterDuke ^^^ the int variable was autoboxed to an Int when the method was called 16:19
guifa2: i think it'd be a tiny difference
[Coke] m: my str $a = "eek"; say $a 16:20
camelia eek
guifa2 I think I can pull off the algorithm to avoid substrs, but at the cost of more math, so I'll need to test the trade off perf wise 16:23
guifa2 . o O ( formatting numbers is a lot more complicated than one might think! )
Tirifto On that note, how do you tell whether or not it’s been autoboxed? 16:24
guifa2 m: my Str $a = 'a'; my str $b = 'a'; say $a.VAR.WHAT; say $b.VAR.WHAT 16:25
camelia (Scalar)
(StrLexRef)
Tirifto Oh, nice! 16:26
16:27 aluaces left
tech_hutch do functions only take the boxed versions? 16:29
guifa2 They can take unboxed, but they have to declare them, and they can't distinguish between different types
so sub foo (int64 $foo) { … } will take an int64, int32, int16, etc 16:30
You have to be very conscientious when working with natives to avoid getting them boxed (basically, you have to strongly type your code that uses them) 16:32
MasterDuke generally you're not supposed to care
tyil >You have to be very conscientious when working with natives to avoid getting them boxed 16:33
that's a good sentence when taken out of context
16:34 aluaces joined
tadzik :o 16:34
guifa2 Yeah, what MasterDuke said is very true. The idea of Raku is for the average person to not even think of the native/closer-to-metal-y stuff 16:35
I would never write a normal script using it, but there's also a tradition of developers (core and modules) torturing themselves to benefit the end-user/programmer, so for those situations, it cna make sense to work harder to eek out certain benefits 16:36
tech_hutch Hm okay 16:38
@ty
(whoops) 16:39
tyil I thought the same thing haha
"so sub foo (int64 $foo) { … } will take an int64, int32, int16, etc" guifa2 oh, so the smaller int types subclass the bigger ones? 16:41
16:41 cpan-raku left, vike joined
Tirifto If I want something to happen every time a class is instantiated (no matter how), would putting it in BUILD/TWEAK/bless be the way to go? (It seems like those should be inherent to the instantiation mechanism, or at least close to it.) 16:43
MasterDuke no, they're not subclasses. fwiw, right now rakudo has some limitations/bugs around how the sized natives are handled (also signed vs unsigned natives) 16:44
i'd recommend TWEAK, but yeah, you could use almost any of those. TIMTOWTDI 16:47
Tirifto In that case, am I missing something in expecting this to say ‘Hello!’? 16:49
p6: class Binode is IO::Path { submethod TWEAK () {say ‘Hello!’} }; Binode.new(‘/usr/bin/raku’);
camelia ( no output )
notagoodidea Every time, I read TIMTOWTDI as Tim tows Teddy.
MasterDuke m: class F { submethod TWEAK() { say "F: " ~ self.^name; }; }; my $b = F.new; my $c = F.new; class G is F { submethod TWEAK() { say "G: " ~ self.^name }; }; my $d = G.new 16:54
camelia F: F
F: F
F: G
