| disbot3 | <simon_sibl> you would have a place in the code I did this and shouldnt have ? like calling myself the SITE.serve(params...) or the self.HTML in the FileList (to avoid duplicate code) ? | 04:44 | |

| disbot3 | <librasteve> @simon_sibl well, you need to assemble a website using site() and to call .serve on it which you do … the form SITE() is export is a bit of a throwback to before I added the .serve method when I had a single service.raku that always called SITE from a context that use Cro::Router … so really no need for SITE (in caps) anywhere. Passing parameter with .serve is as intended and nothing stuck out around self.HTML … it’ll | 15:52 | |
| likely work just to return self since the HTML is called automatically by the parent component. But honestly I’m not really a stickler for a particular style. | |||

| disbot3 | <melezhik.> What’s is status supporting Rakudo binaries for arm / risk-v ? Quoting some people trying to use Spraky those platforms “Update... I remember I started the process of Sparrow/Sparky on Aarch64 and Risc-V but I couldn't remember how far I got... so I just did a refresher. Neither have pre-built RPM repos. Thus I started the more manual way for doing the install. For Aarch64 I had this issue: $ rakubrew download moar-2025.02 | 16:32 | |
| Couldn't find a precomp release for OS: "linux", architecture: "arm64", version: "2025.02" You can try building yourself. Use the `rakubrew build` command to do so. and Risc-V I had this issue: $ rakubrew download moar-2025.02 Couldn't detect system architecture. Current arch is: riscv64-linux-thread-multi Current uname -a is: Linux buildroot 6.12.0-55.34.1.el10_0.riscv64 #1 SMP PREEMPT_DYNAMIC Fri Sep 26 00:36:46 UTC 2025 riscv64 | |||

| tbrowder | ChatGPT says the .List is not required | 19:20 | |

| [Coke] | sorry, that last list should also be List. | 19:23 | |
| tbrowder | i want a List | ||
| shouldn't it be coerced to a List automagically? | 19:24 | ||
| [Coke] | also, you can probably use ```sort: +*``` - shorter. | ||

| camelia | (Seq) | ||
| [Coke] | docs.raku.org/type/List#routine_sort | ||
| sort returns a Seq | |||
| Voldenet | "ChatGPT says the .List is not required" - chatgpt says many things :D | 19:27 | |
| [Coke] | you're using the result of the sort as your return value, so you get a Seq. | ||
| disbot3 | <nahita3882> you can do List() in the signature to have the conversion done for you | 19:28 | |
| Voldenet | huh, you can do that on return type? :O | ||
| m: use Test; my $s="10 1"; sub Foo(Str $s –> List()) { my @ints = $s.words.map({ .Int }); @ints.unique.sort({ $^a <=> $^b }).List }; my @ints = Foo($s); .say for @ints; | |||

||
| [Coke] | that is true on the parameters, but the return type? | ||
| Voldenet | m: use Test; my $s="10 1"; sub Foo(Str $s --> List()) { my @ints = $s.words.map({ .Int }); @ints.unique.sort({ $^a <=> $^b }).List }; my @ints = Foo($s); .say for @ints; | ||
| camelia | 1 10 |
||
| Voldenet | wow that's convenient | ||
| disbot3 | <nahita3882> by the way, .sort must be constructing some sort of a List internally and returning a Seq out of it | 19:30 | |
| <nahita3882> so it could have been made to return a List but perhaps there's a reason for Seq | 19:31 | ||
| tbrowder | well sort has gotten more powerful/confusing over the years fer sure. i do vaguely remember the --> List() "'trick" shown here some time ago | 19:33 | |
| [Coke] | could be using some other iterable. and maybe you're trying to sort an infinite list, or a supply, or... | 19:36 | |
| tbrowder | Voldenet, ref ChatGPT, yes, i have caught errors several times before, and argued about this case and wanted to make sure what is the correct output | ||
| normally "he" admits it when caught in an error, but this time was quite insistent on it should be a List without .List | 19:38 | ||
| disbot3 | <librasteve> took me a while to realise that most listy routines in Raku return a Seq - in other words, Raku tries hard to be lazy wherever possible | ||
| tbrowder | good point, and i'm afraid i am weak-brained on Seq types | 19:39 | |
| disbot3 | <librasteve> @nahita3882 , of course, is correct so in that case there is no performance gain from the Seq | ||
| tbrowder | while i have asking for help, about what year did sort, map, and grep get simplified syntax without needing the braces inside parens? | 19:41 | |
| disbot3 | <librasteve> I think the method call syntax xxx.grep: /it/ has been around as long as Raku ... happy to stand corrected | 19:43 | |
| tbrowder | prb right, but i have always avoided.grep until getting help from lizmat or, ahem, ChatGPT | 19:45 | |
| lots learned to day, thanks all | 19:46 | ||
| Voldenet | nahita3882: the reason is obvious - ideally you'd want to return abstract structures everywhere | 20:08 | |
| returning plain CArray may seem fast, but if someone does .sort(…).head(1) then obviously you can skip all the sorting | 20:09 | ||
| also, (1..10).sort will be no-op | 20:10 | ||
| tbrowder | but revisiting the "--> List()" syntax, doesn't that seem like a hack that should be fixed? | 20:12 | |
| Voldenet | it's a bit like accepting List(), it's very convenient if you actually want to return or consume a list | ||
| tbrowder | i don't understand. is "--> SomeType()" used in other cases? | 20:15 | |
| disbot3 | <librasteve> I use it here harcstack.org | 20:16 | |
| <librasteve> method hx-increment(--> Hash()) { | |||
| <librasteve> otherwise I have to put {{...}} or {%(...)} | 20:17 | ||
| <librasteve> which wastes two lines | 20:19 | ||
| tbrowder | i think i see that, but i don't quite see the need in the List problem case...unless as y'all said Raku wants to be Lazy so you have to be specific. i will try it without a return type in my real code and see what happens. | 20:28 | |
| [Coke] | I think the takeaway is that you can also be lazy here - maybe you just need an Iterable, not a List | 20:32 | |
| tbrowder | ok, i do want a List and i prefer the .List syntax and all this proves the beauty of Raku/Perl and Larry's genius in more than one way to do it! | 20:41 | |
| disbot3 | <librasteve> amen to that | 20:42 | |
| tbrowder | bye for now, it's almost "tea" time... ;-) | 20:49 | |
| disbot3 | <librasteve> ttfn | ||
