Nemokosch Hi 10:40
Thanks for codesections for even caring about my complaint with (@a, @b) on the LHS, also vrurg for the answer under the issue I opened for it 10:41
However, to be honest, I'm a bit disappointed by the lack of attention this draws when this behavior is a top 1 WAT candidate in Raku I have seen so ar 10:42
However, to be honest, I'm a bit disappointed by the lack of attention this draws when this behavior is a top 1 WAT candidate in Raku I have seen so far

Zero_Dogg Is there any quick way to get a filehandle for a Blob object? (usecase: have a Blob from LWP::Simple.get() that I need to pass to Compress::Zlib for decompression, Compress::Zlib throws `No such method 'eof' for invocant of type 'Buf'.`if I provide it with a Buf) 13:10
13:11 jjido left
lizmat hmm... doesn't LWP::Simple provide you with a method to get an IO::Handle compatible object ? 13:12
Zero_Dogg lizmat: not that I'm aware of (and not that I was able locate by skimming through the source) 13:18
lizmat I'm usually using Cro::HTTP::Client nowadys: cro.services/docs/reference/cro-http-client 13:21
I think that has support for decompression built in 13:22
Zero_Dogg Thanks, I'll give that a go. Has something changed with zef recently? It's failing to locate CBOR::Simple (which is an indirect dependency of Cro::HTTP::Client apparently) 13:28
lizmat japhb ^^ ??
Zero_Dogg: perhaps do a "zef upgrade zef", there's been a new release with a lot of fixes 13:29
Zero_Dogg Already have the latest 13:30
lizmat oki 13:31
I'd suggest first installing CBOR::Simple
Zero_Dogg (or so zef says, anyway)
lizmat $ zef --version
v0.13.4
is what I have

Zero_Dogg Okay so that's a lot newer than I have 13:32

ggoebel I must be missing something obvious, but I can't see it. Anyone willing to look at my nearly identical solutions to today's Advent Of Code puzzles in raku and perl and tell me why the raku one gives incorrect answers? 19:55

ggoebel perl: gist.github.com/ggoebel/0dff89aa09...6a4a4110f3
vasko I'd look but I haven't done challenge 5 yet myself :P 19:57
[Coke] style note, you don't have to () the for or if params.
ggoebel coke: perl habits die hard :-) 19:58
gfldex style note, %grid{$x1}{$y} is equivalent to %grid{$x1;$y} 19:59
vasko gfldex Is the same true for arrays? 20:00
gfldex yes
ggoebel noted thx
vasko Cool, I only found out about multi-dim arrays yesterday and thought they were a different beast. 20:01
I'm eagerly anticipating the addition of ragged arrays and views.
gfldex A SemiList is a general concept in Raku.
m: @a = (1,2;3,4); dd @a; 20:02
camelia 5===SORRY!5=== Error while compiling <tmp>
Variable '@a' is not declared
at <tmp>:1
------> 3<BOL>7⏏5@a = (1,2;3,4); dd @a;
[Coke] multi dim is different, yes
gfldex m: my @a = (1,2;3,4); dd @a;
camelia Array @a = [(1, 2), (3, 4)]
vasko Btw, I'm learning raku with AoC and am wondering how to make my $verbose arg from main global neatly. Anything better than `my $VERBOSE; sub MAIN(Bool :v(:$verbose)) { $VERBOSE = $verbose }`?
gfldex call it $*VERBOSE 20:03
ggoebel m: my @a = (1,2;3,4); @a[0;0]=5; .raku.say
camelia Cannot modify an immutable List ((1 2))
in block <unit> at <tmp> line 1
20:03 monkey_ joined
ggoebel so I guess I couldn't have used ++%grid{$x1;$y} 20:05
gfldex that works because $x1 and $y are containers.
ggoebel Cannot resolve caller prefix:<++>(List:D); the following candidates 20:07
match the type but require mutable arguments:
(Mu:D $a is rw)
gfldex vasko: if you want to go fancy on dynvars, this might help: gfldex.wordpress.com/2020/08/17/de...or-dynvar/
[Coke] so, the bug is in the second half (answers for part 1 are correct)
ggoebel I don't get the correct answer for part one when using my input... I do when using the example input 20:08
just a sec, I'll share my input
vasko gfldex: Thanks! I think `say $foo if $*verbose;` is quite neat. :) 20:09
ggoebel input: gist.github.com/ggoebel/d0417c4100...942c6547c5
[Coke] er, sorry. 20:10
gfldex vasko: I would stuff the check against $*verbos into a `sub debug(|c) { say(|c) if $*verbose }` .
[Coke] if you print out the "diag" coordinates it's looping over, they don't look right.
on the real input, first line, it swaps the coordinates, then is incrementing x by 10? 20:11
try making sure you're working with numbers and not strings, I think. 20:12
gfldex ggoebel: did you consider to have a type constraint in line 10? `my (Int:D $x1, Int:D $y1, Int:D $x2, Int:D $y2)` might catch mistakes.
[Coke] afk
20:13 Sgeo joined
vasko gfldex: What's the most idiomatic way to make it support calls as`debug 2, "Only print if -v 2 is set"`? 20:15
I can't find the docs for the `|c` annotation.
ggoebel I changed line 10 to: my ($x1, $y1, $x2, $y2) = .split(/\D+/, :skip-empty).map({+$_});
gfldex vasko: docs.raku.org/type/Signature#Capture_parameters
ggoebel and that fixed it...
thanks! 20:16
vasko Thanks, can I combine that with an optional `Int` infront of it?
I guess the multi signatures is what I want.
gfldex well, you have to do a sub signature then.
ggoebel Still a bit surprised $x1 .. $x2 was incrementing x by 10 20:17
hmm... $x1 .. $x2 -> $x was not incrementing x by 10. So I'm still not understanding how forcing numeric context fixed it. 20:20
gfldex vasko: gist.github.com/9c317047a1cabafcdc...98a76425e7 20:21
vasko: you just made me find an ENODOC :) 20:23
two ENODOCs acutally
well, I better check roast before I accuse to docs of incompleteness …
ggoebel what is perl automagically doing that I take for granted that raku is not? 20:28
vasko Thanks, I got that bit, but I want to have it take a level as well. 20:29
I guess I can just check `|c` is a Seq and then test if `|c[0]` is an Int, then `say(|c[1..]) if $*VERBOSE >= |c[0]`? 20:30
ggoebel vasko: not sure if this is what you're looking for... docs.raku.org/language/operators#prefix_| 20:32
vasko I think I'll settle for `sub verbose(:$n = 1, |c) { say(|c) if $*verbose >= $n }` so I can do `verbose :n(3), 'Only print this if the program is called with -v=3 or more'` 20:35
gfldex vasko: you can have a `sub MAIN(:v($*VERBOSE), :D(:debuglevel(*$DEBUG-LEVEL)) = 1) {}` 20:50

camelia (12 11 22 21)
ggoebel m: ("12".."19").flat.say
camelia (12 13 14 15 16 17 18 19)
MasterDuke ranges operated by calling .succ docs.raku.org/routine/succ#(Str)_method_succ 21:54
gfldex vasko: Why so verbose? `».Int` will cut it! :-> 21:55
vasko gfldex I'm still learning. Cool, any time I would want to use `.map` over `»`? 22:01
gfldex It's a hyper ans as such a candiate for auto-threading. Beside that, it's just shorter for simple cases. 22:02
ggoebel MasterDuke: thanks for the link to the relevant docs. Maybe I'm being dim, but I still don't understand how "12".."21" increment steps result in (12 11 22 21)
"Ranges always go from small to larger elements; if the start point is bigger than the end point, the range is considered empty." 22:03

ggoebel per Coke and gfldex's suggestions, I'll just have to remember coerce things into Ints to avoid character ranges. 22:12
I think I prefer changing line 10 to: my (Int(Str) $x1, Int(Str) $y1, Int(Str) $x2, Int(Str) $y2) = .split(/\D+/, :skip-empty); 22:14
