atweiden-air_ leont: i think i get it. so .uc is being applied to each list, not to each list element? 00:02
leont Yeah. Map iterates over all elements of @a, which are lists, and calls .uc on them
atweiden-air_ makes sense 00:03
leont .uc and other stringy methods are defined on lists, and effectively do .Str.uc

ToddAndMargo Windows 11 pro 22H2. 01:52
You guys have been helping me figure out NativeCall and Pointers.  I finally got it figured out.  I just posted an example over on the perl6 mailing list of use of pointers for calling Windows DLL's and for copying data out of structures when given a pointer to the structure.
I get a pointer and length from "GetComputerNameA" and then show how to use the pointers to copy the data pointed to with "memcpy_s".
Maybe someone would want to clean this up and post it in Raku's example section?
Thank you all for the help!

I'm sure this is written down somewhere or we have talked about it - but how do array literals work? 09:20
[1] - this is a one-element array 09:21
[<a b c>] - this is a three-element array, despite the List inside
in fact, even [[1, 2]] "auto-flattens" 09:22
I know you can make it a scalar or add a comma, I'm just curious how this is processed

grondilu I may be wrong but it shouldn't be too hard to assess whether an expression can be compiled or not. For instance in my implementation of md5 (github.com/grondilu/libdigest-raku...t.rakumod) I have blobs and arrays defined in a BEGIN because they depend only on literals. It occurred to me later that the compiler could figure out by itself that these are constant arrays that could and ma 11:22
Nemokosch in that case, why don't you declare them as constants? 11:23
grondilu I did in previous versions, but it doesn't change the fact that it seemed superfluous to me. 11:24
Nemokosch What I don't know are the technical constraints - but frankly, I don't find the demand completely justified in the first place 11:25
code runs, well, at runtime, as a main rule
even in archmage C++
if you want to run code by the compiler, you indicate that 11:26
sounds sane to me
lizmat grondilu how do you know that Rakudo actually doesn't do that already ? 11:27
ok, looking at the code, that might actually be less than trivial :-) 11:29
grondilu lizmat: I had discussed few weeks ago here about whether it made sense to write `constant $ = Blob.new: some-code(@literal-values);` and I was told it did. Also we made some tests and it was quicker with `constant $ =` 11:30
well, not on first execution but on the next ones, IIRC
Nemokosch I think lizmat meant to say that there might already be optimizations of the kind you are looking for
but it turns out that maybe not? 11:31
if pure functions were strongly indicated in Raku, this could go further, I suppose
lizmat well, for instance: if you write "42 + 666", it will constant fold that to 708
grondilu To make sure I may write a specific test with a very expensive function I suppose.
lizmat and similar cases 11:32
if the static optimizer sees an expression consisting of constant values only, it will fold it
grondilu There is a pure trait that I considered using at some point, but I thought it was simpler to just use a BEGIN phaser
lizmat yeah, using BEGIN makes it easier to reason about as a developer 11:34
grondilu take for instance this : `blob32.new: map &floor ∘ * * 2**32 ∘ &abs ∘ &sin ∘ * + 1, ^64`. Do you think it would be compiled ASAP?
it's all constants and pure functions 11:35
or "constant fold", I'm not familiar with that terminology 11:36
I know I can just use BEGIN, but I like writing short code, and I'll take anything I can get to simplify things. 11:38

tbrowder i have the attribute list from self.^attributes and want the value of each 13:44
13:45 derpydoo joined
tbrowder i have tried: attr.get_value 13:45
self.attr.get_value 13:46
self.get_value: attr
i have done it successfully in the past but don't remember the syntax 13:47
btw, i think my problem here is the same on Todd has, the docs, just like the *nix man pages, don't show the basic use before jumping into meta land assuming the reader already knows a lot about the subject 13:49
lizmat I believe it is attr.get_value(self) 13:51
m: class A { has $.a = 42 }; say A.^attributes[0].get_value(A.new) # tbrowder 13:52
camelia 42
tbrowder thnx, i used attr.get_value: self 13:56
worked great. THANKS, lizmat

Pair.ACCEPTS documentation fix
Anton Antonov <@779471841270038528> I think it has something to do with the weighted random sampling over Mixes. (Good question!) 16:01
melezhik AA ++ 16:02
Anton Antonov I also, changed the logic of the default selection of random pet names in "Data::Generators", because it seemed slow with very modest sizes (e.g. 4000.) 16:03
melezhik I mean why it is slower for 2022.07 rakudo?
Anton Antonov Maybe the Mix sampling with `roll` was changed in some way between 2022.07 and 2022.06 ? 16:04
<@779471841270038528> It did not occur to me to check what is the speed with older rakudo versions... 16:11
