codesections Well, searching the Internet for 18446744073709551612 tells me that it's both one of the bests planets in No Man's Sky and a valid FedEx tracking number 01:26
01:26 linkable6 left
codesections so I guess Raku isn't up to storing all NMS planets in a single array 01:27

codesections ...or whatever _really bad_ program design that would need an array with the length of a FedEx tracking number 01:28

PimDaniel \o 12:08
I'm trying to translate Python code and Python preserve hash key type , well say , at least String/Num. 12:09
But Raku hash key is allways and Str. How could we do a workaround for this?
tyil PimDaniel: do you want to mix int and str keys in a single hash? 12:11
PimDaniel tyil. I do not understand your question? Sorry i'm a few tired. 12:12
12:12 xinming left, xinming joined
tyil docs.raku.org/language/hashmap#Non...ject_hash) 12:12
PimDaniel: do you want to make all keys in a Hash of type Int, or do you want to be able to use both Int and Str keys in a single Hash? 12:14
PimDaniel My entry hash is '%(john => [ 1,2,3] , june => [4,5,6]) or %(1 => [8,11,12], 4 => [6,9,2])
tyil in that example, why would you need to keep the keys as Ints? I don't think anything would break by stringifying them 12:15
PimDaniel which leads numbers key 1,4 to string : "1", "4"..., i look at your url, thank's.
Good question: it is due to the algorithm that commutes keys to values (and the opposite) and compare them. And sometime this leads to a type mismatch. 12:17
I should probably post the code but it is quite complex: you have 3 methods, a while(True) loop and and recursing method. The algorithm is Hopcropft and Karp bipartit graph. 12:19
The problem is "probably" i should have to reconsider the problem from scratch with Raku. 12:22
12:23 wamba left
PimDaniel But since i discovered what is the problem and am close to achieve it, i try to find a solution. 12:24

tyil good luck

PimDaniel Pfff i don't even understand at all the sense of := vs = assignment. And such of all why and when should i use one or the orther. This is very confuse to me. 13:20
13:23 JRaspass left 13:40 jjmerelo left
PimDaniel ok think it's just an object. 13:40
kinda address.
lizmat PimDaniel: in Raku, hashes by default will coerce their keys to Str 13:50
but if you want to have a different types of keys, you can specify that 13:51
m: my %oh{Any} = 42, "a", 666, "b"; say .WHAT for %oh.keys 13:52
camelia (Int)
(Int)
PimDaniel True lizmat, i'm studing this.
lizmat oki!
PimDaniel I try to have an %h{Any} but i discover my problem else elsewhere. 13:53
Confusion with hash and positionnals.
when we write a => b, c => d; is it hash or positionnals? 13:54
Raku is full of confusing concepts.
and is not easier than Perl5 at all.
lizmat Well, if you're coming from Perl, then you have a lot of false friends :-) 13:55
PimDaniel True!
I think it's even better to comme from Python or PHP. 13:56
lizmat ok, let's take this one step at a time
my $b = a => 42
PimDaniel hum...
lizmat in that case, a => 42 is a Pair
if you say:
PimDaniel hum hum...
lizmat if you say: my $l = a => 42, b => 666
that's a List of Pairs
PimDaniel ok 13:57
lizmat note that in Raku, the comma is the List builder, **not** the parentheses
if you say: my %h = a => 42, b => 666
then you're initializing a hash with a List of Pairs
the hash initializer will take a Pair as indicating a key and value to set 13:58
but it will also take non-Pair values
if you say: my %h = "a",42,"b",666
then that would be the same, because the initializer will take alternating values to be key/value 13:59
m: my %h = "a",42,"b"
camelia Odd number of elements found where hash initializer expected:
Found 3 (implicit) elements:
Last element seen: "b"
in block <unit> at <tmp> line 1
PimDaniel ok i understand this and this is what i observed.
SO, suppose i want to initiate a hash{Str} with a constructor. 14:00
lizmat so that would mean you would **only** accept Str as keys, and *not* have have any other types coerced to Str, right ? 14:01
PimDaniel i don't need to pass the constructor parameter a hash: i can pass it a list of Pair, No?
lizmat yup
PimDaniel for example : 1 => [3], '1' => [1,2,3],'2' =>[10,11,12],2 => [3,4,5], 6 => [3], 7 => [3,5,8], '7' => [11,1,2] 14:02
whatch that you have a trap here!
I'm very twisted! 14:04
lizmat m: my %h{Any} = 1 => [3], '1' => [1,2,3],'2' =>[10,11,12],2 => [3,4,5], 6 => [3], 7 => [3,5,8], '7' => [11,1,2]; dd %h
camelia Hash[Any,Any] %h = (my Any %{Any} = "1" => $[1, 2, 3], 1 => $[3], 2 => $[3, 4, 5], "2" => $[10, 11, 12], 6 => $[3], 7 => $[3, 5, 8], "7" => $[11, 1, 2])
lizmat m: say 1 === "1"
camelia False
PimDaniel yess, i have === into my algorithm 14:05
it it is especially the reason why... all of this.
in fact : i'm loosing my types in my constructor parameters. 14:06
lizmat ah, gist?
PimDaniel How do we declare a list of positionnal as parameters in a new sub 14:07
??
well this is another question.
14:08 Sgeo joined
lizmat sub foo($one, $two) 14:09
?
ah, a List of positionals?
yeah, that is still underdeveloped in Raku 14:10
PimDaniel In other words : what is the that could feet for 1 => [3], '1' => [1,2,3],'2' =>[10,11,12],2 => [3,4,5], 6 => [3], 7 => [3,5,8], '7' => [11,1,2] directly sent to the constructor.
lizmat m: sub foo(List $l) { dd $l }; foo 1,2
camelia 5===SORRY!5=== Error while compiling <tmp>
Calling foo(Int, Int) will never work with declared signature (List $l)
at <tmp>:1
------> 3sub foo(List $l) { dd $l }; 7⏏5foo 1,2
lizmat m: sub foo(List $l) { dd $l }; foo (1,2) 14:11
camelia $(1, 2)
PimDaniel probaly make a subset
lizmat yeah, there's that, or maybe look at the Rake module in the ecosystem
PimDaniel but i need to preserve types as is.
lizmat alternately, (which is probably better for performance anyway), is to create a class for that list 14:12
PimDaniel I think i allready dit it: i must look at my codes.
lizmat in Perl, using a hash or a list as an object, is usually the fastest way to do things, because of the overhead of accessors 14:13
PimDaniel hum may be. The 1st goal is to preserve the types into my hash class attribute at least.
lizmat in Raku, using objects is almost *always* faster
PimDaniel Good to know.
lizmat so that's one of the false friends you need to get rid of 14:14
PimDaniel I watched it is sometimes very slow without good reasons.
lizmat see e.g. github.com/Raku/CCR/blob/main/Rema...-classy.md 14:15
PimDaniel I mean compare to others interpreted langages like Per5,Python,PHP, and others.
Thank you very much.
PimDaniel lizmat : your url is very interesting: raku is so wide than i'm allways wondering : what is the best way? And often the way i choose does not feet. 14:22
lizmat yeah, it can be overwhelming initially
just that you're at a beach, and are learning to swim: nobody expects you to be able to swim across :-) 14:23

codesections .ask moritz: do you happen to remember what the index in the old irclog.perlgeek.de URLs corresponds to (e.g., the `13961377` in irclog.perlgeek.de/perl6-dev/2017-...13961377)? Is it a timestamp of some sort? (I'm going to try to update some links to point to the colabti archive) 15:01

codesections or if anyone else knows ^^^^ 15:01
moritz codesections: that ID was an autoincrement key (with negative values for messages that were back-imported later 15:03
