Frozenset hello, how may i get a handle to a method to, say, inspect its signature? 12:00
I mean:
m: &abs.signature
camelia ( no output )
Frozenset &A-Class.method.signauture 12:01
m: say &abs.signature; 12:02
camelia ($, *%)
Frozenset Okay with functions but what about methods?

MasterDuke the docs explain the difference between can and find_method 12:06

codesections huh, I've always used .^lookup instead of .^find_method. 13:44
MasterDuke right, forgot about that one 13:47
codesections is there any difference between those two? 13:48
m: say Int.^find_method('abs') === Int.^lookup('abs')
camelia True
codesections m: say Int.^find_method('not-here'), Int.^lookup('not-here') 13:50

mykhal hi again. services like camelia and evalable6 are handy. can some of them test a code snippet in multiple notable rakudo versions backwards and report result differences and failures ? 15:34

codesections wait, really: 21:03

camelia 5
codesections m: say Int.^lookup('abs')(-5); say Int.^lookup('abbs')(-5) 21:06
camelia 5

codesections that's pretty odd – and I'm not sure if it's a feature or not 21:07

AlexDaniel Altai-man: the one with the release number that is incorrect :) 21:19
Altai-man: gist.github.com/Whateverable/19d6d...dbeda4c9a5
2021.06 should say 2021.06, not 2021.05-something
doesn't matter anymore I guess 21:20
it happened before too
Altai-man AlexDaniel, I fail to see how that could happen. I mean, there is github.com/rakudo/rakudo/pull/4417...83a86fc4dd <- and github shows it's included under the 2016.06 tag? 21:25
anyway, I think I'll retire in two relesaes 21:26

AlexDaniel oooooooh interesting
cuz I also fail to see how it can happen!

AlexDaniel Altai-man: great work! Well deserved retirement 🤗 21:32
Altai-man: some successor volunteered already?
Altai-man AlexDaniel, not really, but I also did not "announce" it properly yet, just told it here and there a couple of times in "well, maybe sometime in the future" sorta way, so the people are not worried yet. :) 21:33
AlexDaniel Altai-man: if you stay for 3 releases then you'll break the record 😀 21:34
Altai-man AlexDaniel, well, that's my plan. :P
AlexDaniel Altai-man: yes, but 3, not 2, if I'm not mistaken 21:35
or 4 if we count point releases as cheating 🤔 21:36
Altai-man AlexDaniel, dunno, maybe I'm wrong as well. I counted it as 2, doesn't matter much. I mean, after first 10 one or two more start to look alike.
AlexDaniel not making your life easier am I
Altai-man AlexDaniel, well, I counted both point for you and me included.
AlexDaniel Altai-man: dunno, some releases are special! Based on the list, 2020.08 looked like one 😛 21:37
Altai-man: but you did great! Thank you for your work! 21:38
Altai-man AlexDaniel, noooo, I don't want to remember this one, what an utter failure, heh.
.oO ( just blame the man who distracted me a lot that day )
AlexDaniel, I cannot express enough gratitude to YOU though, I mean I am just starting the scripts once in a while and you did made all that tooling, that's very helpful. 21:39
21:39 patrickb left
AlexDaniel if I didn't do it, you would've had one made by Zoffix. It was a big step too, mine was just an iteration on that 21:40
there was Toaster instead of Blin and a bot instead of the sakefile, both did the job alright 21:41
Altai-man fair enough 21:42

[Coke] (releases) I'm glad you (and others) have gotten to point where it's mostly routine. Thank you! 22:24
(you all)
vasko Hi, anybody able to point me in the right direction to convert a list into a hash? In perl5 I would do `▶ perl -M'Data::Dump qw(dump)' -e 'my %sq = map { $_ => $_ ** 2 } (0..4); dump \%sq;' 22:32
{ "0" => 0, "1" => 1, "2" => 4, "3" => 9, "4" => 16 }`
In raku I'm failing with: `> (0..3).map( * => * ** 2); 22:33
(0 => 1 2 => 9)`
moon-child so you want the array indices to be the keys of the hash? 22:34
oh, no, ignore me
so something like (* => * ** 2) is actually a function of _two_ parameters 22:35
so you would need something like {$_ => $_ ** 2}
m: say (0..4).map({$_ => $_ ** 2}).hash 22:36
camelia {0 => 0, 1 => 1, 2 => 4, 3 => 9, 4 => 16}
vasko Ah thanks, I was missing the `.hash` cheers :)
moon-child well, you don't actually need the .hash depending on what you do with it 22:37
m: my %x = (0 .. 4).map({$_ => $_ ** 2}); say %x
camelia {0 => 0, 1 => 1, 2 => 4, 3 => 9, 4 => 16}
vasko Oh I see, I really need to reread the manpages and understand the `Whatever` closures over normal subs/functions I'm used too. 22:38
