rypervenche Why would this test not work?: is first(Int, (1..10)), 1; 00:13
codesections m: use Test; is first(Int, (1..10)), 1; 00:15
camelia ok 1 -
codesections It passes, but the problem with it is that it's using string comparison (`eq`) to compare 00:16

Skarsnik Hello, I am super confused, I have some code like that (in a loop): say $arg.raku, $arg.WHAT; 09:27
say "I am a list" if $arg ~~ List; but it never input I am a list, even when WHAT is (List)
Altai-man Skarsnik, can you reproduce it here? 09:30
Skarsnik No because, it works properly in a one liner x)
Altai-man :Z
Not sure it can be helped without much info, alas. 09:31
What if you try `if $arg<> ~~ List`? (just a wild guess)
09:31 aluaces joined, zacts joined
Skarsnik m:my @foo = ((1, 2), Buf.new(4 09:32

Altai-man () is redundant 09:36
m: my @foo = (1, 2), Buf.new(40); for @foo -> $a { say $a.raku, $a.WHAT; say "I am a list" if $a ~~ List }

09:37 ex_nihilo left
Skarsnik that does not tell me why my ~~ Type check never work in my module xD 09:38
Altai-man Yes, but still. :P 09:39
Skarsnik, what if you try =:= instead of ~~? 09:40
Skarsnik (also I mess up a fix in one of the Test method x)
09:42 aborazmeh left
Skarsnik No luck x) 09:42
09:45 MasterDuke left
Skarsnik say "I am a list" if $arg.WHAT.raku eq "List"; work xD 09:45
dakkar eww 09:46
m: my @a;say @a.WHAT
camelia (Array)
dakkar that's the string representation of a metaclass instance, right?
m: my @a;say @a.WHAT.WHAT
camelia (Array)
dakkar is now confused
Skarsnik m: say ().WHAT.raku 09:47
camelia List
moritz no, that's the typ object
*type
the meta class is accessbile through HOW
m: my @a; say @a.HOW
camelia No such method 'gist' for invocant of type
'Perl6::Metamodel::ClassHOW+{<anon>}'. Did you mean 'isa'?
in block <unit> at <tmp> line 1
moritz m: my @a; say @a.HOW.name
camelia Too few positionals passed; expected 2 arguments but got 1
in block <unit> at <tmp> line 1
moritz m: my @a; say @a.HOW.^name
camelia Perl6::Metamodel::ClassHOW+{<anon>}
dakkar oh, right
moritz m: say 42.HOW.^name
camelia Perl6::Metamodel::ClassHOW
dakkar m: ().WHAT ~~ List
camelia ( no output )
dakkar m: say "ok" if ().WHAT ~~ List 09:48
camelia ok
dakkar Skarsnik: something like that?
Skarsnik this did not work etheir
dakkar I think we need more context then
09:52 maggotbrain left
Skarsnik the code boil down to 09:52
m: class A { multi method foo(**@args) {for @args -> $arg {say "I am a list" if $arg ~~ List}}}; my $a = A.new; $a.foo((1, 2), (2, 3), Buf.new(<1 2>))
camelia I am a list
I am a list
Skarsnik but this work 09:53
dakkar then there's something weird in the parts you boiled away ☺ 09:54
like, that `multi` is useless here, but maybe you have other candidates in your actual code? 09:55

dakkar ah, `.push:` eats the rest of the line 10:02
Skarsnik: the slightly modified version at my gist seems to work 10:03
Skarsnik this alone works for me too
dakkar so the problem is somewhere else, keep digging
10:04 k-man left
dakkar notice how I had to change `@datas.push:$arg if…` to `@datas.push($arg) if…` 10:05
Skarsnik yeah @datas get properly filled now with this change, but still no luck with List check 10:06

codesections Today I Learned that this syntax exists in Raku: 12:36
m: my regex word { \w+ }; 'foo bar' ~~ /<new-name=.&word>/; say $<new-name>
camelia ｢foo｣
codesections (or without the & inside a grammar) 12:37
I should probably add that to the docs 12:39
dakkar that is calling the &word sub/regex on the current cursor(?) 12:51
if you're not in a grammar, you can just <new-name=word>

codesections I have a data structure that, conceptually, is a tree of Hashes/Arrays (think JSON). But, in practice, many of the Arrays have ended up being Seqs instead. Is there any good reason to convert them back to Arrays, or should I just leave them as Seqs? 16:16
16:16 billN1VUX left 16:17 billN1VUX joined
Altai-man codesections, it depends on who will stream them down the line. Seqs cannot be iterated twice without a `.cache` call which might be really annoying if you are getting "Seq cannot be iterated" exception somewhere deep in eval code (think Cro::WebApp). Converting to an array is less perf, of course. 16:18
So think in terms of what API you want to have.
timotimo i have a snippet that can help you debug "has already been consumed" error messages 16:19
codesections Altai-man: yeah, that's actually how I noticed the issue: working with the data structure, I noticed that I'm needing to add `.cache`. So now I'm trying to decide if I should deal with that as the consumer of the API
or tweak the data structure to convert to Arrays after each map, etc 16:20

spent twnety minutes now searching through docs, but I don’t know how to ask the question well enough to find the answer.
