zacts hello, are there any good books for learning raku? 02:11
I see this: docs.raku.org/language.html 02:12
but I don't see anything like modern perl for raku
the docs.raku.org seem to contain mainly topic references, at least as I'm skimming it now
02:35 aborazmeh left
timotimo zacts: you can have a look at perl6book.com 02:44
lucs Hmm... Not sure why "Learning Perl 6" is in the "I'm a novice" section. 02:47
Even non-novices should enjoy that book's approach. 02:48

elcaro when for-looping over an iterable assigned to a scalar, is there any semantic/performace differences between `for $x<>`, `for $x[]`, and `for $x.list` ? 13:36
13:38 stoned75 joined 13:44 MasterDuke left
jnthn for $x<> is a simple removal of the Scalar container, so the most direct; .list will cause storage of elements if it's a Seq, which may be undesirable if wanting laziness. 13:47

jdv79 any general differences between ubuntu and apline that would cause a nativecall to behave differently? 15:48

jdv79 that makes sense, thanks 16:27
jjmerelo Hej 16:28
16:28 shadowpaste joined
jjmerelo What would you say is the equivalent of the __name__ == __main__ in Python in Raku? 16:28
16:28 NODE joined
jjmerelo Best I could come up with is to compare $*PROGRAM to file name 16:29
dakkar in p5 I've used `!defined caller`
jdv79 just curious - why would you want to do that? 16:30
iirc in python its how they flip a file from action like a module or like a program or something.
*acting 16:31
jjmerelo same reason as in python
Load a program to test whatever is defined there without starting the actual main part of the program.
I'm using Cro::HTTP::Test to test a microservice which can be also run independently 16:32
guifa2 For POD, is there any way to link to code objects (classes, methods, or even blocks)? I'm 99.9% sure the answer is no as links only go to other POD documents or URIs, but I feel like it might be a fairly useful thing to do. 16:35
16:35 NODE left
jjmerelo guifa2 there was an ad-hoc way of doing it, but it was obliterated in 2018 16:38
guifa2 Ah. I ask because there are sort of two separate POD annotations — the one that flows with the document, and the one that attaches to classes/methods/etc. It seems like it would be good to be able to link to content of either 16:39
16:39 xinming_ left 16:40 xinming_ joined 16:46 poohman left
jjmerelo guifa2 can you clarify that? 16:46
16:47 NODE joined
jjmerelo Pods and comments are the same in Raku, they are part of the documentation "braid". So if you intersperse declarator blocks with POD blocks, they will both be parsed by the compiler 16:47
dakkar maybe he means the bits you can get via `.WHY` 16:51
16:53 poohman joined
guifa2 dakkar correct 16:57
dakkar guifa2: so you'd like to L<#subname> or L<#classname>
16:58 guifa2_ joined
guifa2_ the .WHY is functionally different, in that it's not really a parallel document that happens to be interleaved with the code, but it's actually literally attached to a single code entity 16:59
s/.WHY/.WHY-style annotations 17:00
dakkar declarator blocks also appear in the $=pod array 17:01
17:01 guifa2 left 17:05 molaf joined
guifa2_ they do — and have a WHEREFORE method, that other pod elements don't 17:08
dakkar correct 17:09
now, I see some problems
the pod6 documentation says that L<> can link to a *section*
but declarator blocks are not (I think) sections
also, they don't get names
so, improvement: have them get the name of the thing they're documenting 17:10
then, make them link targets
we probably don't need namespacing
guifa2_: I think this needs a bug report 17:11
17:12 kensanata left
guifa2_ It possibly needs a bit more, possible a raku problem solving issue — for example, if you do a class with methods, and attach declarator pod to all of them, they are presented as top-level pod elements. That feels....off, I mean, you *can* say $=pod[2].WHEREFORE.package 17:16
to try to figure out that in rendering it might need to be nestled inside of a class 17:17
17:17 dakkar left
guifa2_ But I can't think of how to figure out handling a class within a class — classes don't have equivalent .package methods that I can see 17:18
