SmokeMachine .tell guifa I've been playing with the idea of matching RakuAST and saw that could work for any object (like your objex). it's far from ok yet and I plan writing a slang to make that look like grammar and also accept actions, but do you have any opinion about that? usercontent.irccloud-cdn.com/file/.../image.png 02:27
tellable6 SmokeMachine, I'll pass your message to guifa
SmokeMachine .tell guifa on this case, TOP is not special and any method inside the "grammar"would be searched on the ast/object tree... 02:28

Nemokosch why does :kv flatten the values? 09:15
say you have { a => (1, 2, 3), b => (4, 5, 6) }
the kv version of this would be something like ('a', 1, 2, 3, 'b', 4, 5, 6)
eh damn, it's not this easy to reproduce... 09:17
well then, I will be back once I pinpointed what went wrong for me
what I can quickly guess is that this has something to do with itemization 09:19
which in turn might have something to do with constant Maps
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); dd $_ for %a.kv 09:36
camelia "b"
(4, 5, 6)
"a"
(1, 2, 3)
lizmat m: my constant %a = a => (1,2,3), b => (4,5,6); dd $_ for %a.kv 09:37
camelia "a"
(1, 2, 3)
"b"
(4, 5, 6)

lizmat it's the Mappiness, not the constantness 10:00
10:00 jjido left
Nemokosch is this intended? seems quite odd to me 10:03
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); dd %a<>
camelia Map.new((:a((1, 2, 3)),:b((4, 5, 6))))
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); dd %a
camelia Map.new((:a((1, 2, 3)),:b((4, 5, 6))))
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); use nqp; dd nqp::iscont(%a)
camelia 0
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); use nqp; dd nqp::iscont(%a<>) 10:04
camelia 0
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); say %a.kv.iterator
camelia Map::KV.new
lizmat m: my %a is Map = a => (1,2,3), b => (4,5,6); say %a.kv<>.iterator
camelia Map::KV.new
lizmat feels like an issue is in order 10:05

Nemokosch is there a mutable interface to the values of a Hash, all at once? %hash.values[0] is a Scalar but %hash.values itself is a Seq, I can't just assign to that 10:44
10:45 jjido joined
seems like %hash.values[*] does the trick 😄 10:46
> %options-left.values[*] X(-)= 10
I propose the concept of More Than Awesome
How can this just work and do what I wanted to do... 10:48

lizmat m: my %h = a => 41, b => 136; $_++ for %h.values; dd %h 11:07
camelia Hash %h = {:a(42), :b(137)}
lizmat the magic of containers!
Nemokosch yes, that one I knew, that's also pretty good 11:08
but this X(-)= 10 on a list of containers is just... out of this world
and, of course not because of this "trickery" in particular, but my solution is actually pretty fast for the weeklies, up until 10-ish 11:09

SmokeMachine Nemokosch: why the `[*]` wouldn't it work without it? 11:14
tellable6 SmokeMachine, I'll pass your message to Nemokosch
SmokeMachine m: my %a = a => 1, b => 2; %a.values X-= 1; say %a
camelia {a => 0, b => 1}
Nemokosch originally I didn't put X there and then it surely didn't work 11:15
SmokeMachine m: my %a = a => set(1, 2, 3), b =>set( 2, 3, 4); %a.values X(-)= 2; say %a
camelia {a => Set(1 3), b => Set(3 4)}
11:15 Nemokosch joined
Nemokosch okay, the solution runs in about a minute for n=15 11:15
I'd say that's still acceptable for an actually exponential problem 11:17
SmokeMachine m: my %a = a => set(1, 2, 3), b =>set( 2, 3, 4); %a.values >>(-)=>> 2; say %a
camelia Cannot modify an immutable Bool (True)
in block <unit> at <tmp> line 1
Nemokosch m: my %a = a => set(1, 2, 3), b =>set( 2, 3, 4); %a.values = %a.values X(-) 2; say %a
camelia Cannot modify an immutable Seq ((Set(1 2 3) Set(2 3 4)))
in block <unit> at <tmp> line 1
tellable6 2022-11-18T11:14:01Z #raku <SmokeMachine> Nemokosch: why the `[*]` wouldn't it work without it?
Nemokosch see? that was my original attempt and this failed
actually, I'm not sure what sort of black magic makes X(-)= work, then 11:18
in what order is this resolved?
now I'm starting to think it's X[(-)=], I originally was thinking of [X(-)]= 11:19
SmokeMachine m: my %a = a => set(1, 2, 3), b => set( 2, 3, 4); say %a.values X(-) 2 # The problem is setting it back to values...
camelia (Set(3 4) Set(1 3))
SmokeMachine X(-)= will set the value for each container returned by .values and not to the .values itself... 11:21
Nemokosch: `%a.values X(-)= 2` kinda is equivalent to `for %a.keys -> $key { %a{$key} (-)= 2 }` 11:23
that's equivalent to `for %a.keys -> $key { %a{$key} = %a{$key} (-) 2 }` 11:24
m: my %a = a => 10, b => 20; say %a.values = 1, 2 # but on the other hand 11:25
camelia Cannot modify an immutable Seq ((20 10))
in block <unit> at <tmp> line 1
Nemokosch eventually, the result will be the same 11:27
I was thinking of less mutation on the way
anyway, this explains why it worked in the first place :D thank you for the hints 11:28
11:30 razetime joined
Nemokosch something that boggles me hard, though... 11:44
I compared my performance with other contenders and I noticed that someone who does something similar but way simpler, actually beats me like 5 to 1 11:45
without doing any .race
I removed .race and suddenly my performance went a magnitude UP
now N=15 runs in about 6 seconds 11:46
what can be the takeaway of this? function calls are expensive with threading?
that's the main thing I can think of, it's a recursive function after all
11:57 Nemokosch left 12:07 reportable6_ left 12:09 reportable6 joined
moritz the first takeway is that you should always benchmark before and after optimizing :-) 12:15
the second is that .race is only good if each individual element takes long to process 12:16
if instead you have very many elements that are somewhat quick to process, you might succeed by manually specifying a pretty big batch size 12:17
Nemokosch perhaps I should but that's never gonna happen for weekly challenge solutions 😛 12:28
well, this was a branching recursion so probably it could have made sense to race over the first couple of levels and then just count them sequentially 12:33

[Coke] RSC folks - can we get a linkedin post for the volunteer infra "job"? 15:29
Would help with finding candidates with devops background who are looking to volunteer. 15:30
putting a copy on linked in will make it easier for me to get eyeballs on it, at least. 15:31
vrurg [Coke]: looks like a good idea. Could you mail it to [email@hidden.address] please? 15:33
