timotimo jaldhar: you can use both none($year) %% 100 ot say "year isn't evenly divisible by 100", or you can use !%% 00:35
yoleaux 23 Jun 2019 21:10Z <MasterDuke> timotimo: bunch of relevant-to-you chat today. starting at colabti.org/irclogger/irclogger_lo...9-06-23#l6
timotimo you'll probably want to use %% instead of %, because %% gives true/false, whereas % gives you the remainder, but if you're only caring about "evenly divisible yes/no", the number is just extra baggage
or something :)
and for symmetry reasons there's a negation metaop, so every operator is negatable :) 00:39

08:43 squashable6 left
antoniogamiz If I'm calling a method with 2 arguments but it gives an error saying that I'm calling it with 3, what could be wrong? 08:44
robertle_ perhaps it thinks it's a sub, and you think it's a method?
do you have an example to look at? as in call site + signature? 08:45
antoniogamiz call site => say $registry.lookup("test1", "d");
signature => method lookup(Str $what, Str :$by!) {
08:47 squashable6 joined
robertle_ ah! your second argument is a by-name argument, so the callsite would have to be .lookup("test1", by => "d") or the signature could drop the colon 08:48
docs.perl6.org/type/Signature#Posi..._arguments
antoniogamiz aaaaaaaaaaaahhhhhhhhh riiiiiiiiight 08:49
thanks a lot! I hadnt notice!!
robertle_ btw, what is the more "canonical" (if such a thing exists) way to use a named arg? by => "d" or :by("b")? 08:50
and are there any good reasons to use one over the other?
antoniogamiz mmmm I am not sure, sometimes I like => syntax because is quite clear
you can even do this :234value 08:51
that's the same as value => 234
08:51 nepugia joined
robertle_ oh wow, didn't know! 08:52
not sure I like it, looks 'cute' but confusing for anything but numbers as the value
antoniogamiz yep, I prefer => most of the time 08:53
sena_kun it depends on the situation, => is usually enough, but sometimes :foo() looks nicer
for example, in Cro we have: 08:54
>parsers => @!body-parsers, next => $request.body-parser-selector
but
>emit Cro::HTTP::Response.new(:500status, :$request);
antoniogamiz sena_kun: uoh, good use for that last case :oo 08:57
robertle_ hm, it kinda breaks the "symbolic" part of a name, right? If I change a variable name in one place it might have a consequence somewhere else. but I guess Perl 6 isn't that strictly symbolic anyway... 09:01
sena_kun well, renaming may cause breakage like this, but it is true for every language with named parameters 09:03
I am not sure the syntax of named argument changes anything in this regard
sena_kun .oO ( we need to support that smart refactorings in Comma, but firstly need to refactor a couple of things ) 09:04
09:04 wadda joined 09:06 wadda left
robertle_ well, I didn't mean changing the name in the signature, that clearly breaks things. I meant at the call site: 09:08
the emit Cro::HTTP::Response.new(:500status, :$request); case for example. if I refactor my calling code and rename $request to $location-backend-request because I now have multiple requests flying around and get confused about them, then that breaks things 09:10
and renaming a lexical everywhere in that lexical scope seems like something that should be safe...
sena_kun yes, in this code it goes from `:$request` to `request($location-backend-request)` 09:11
Geth ¦ doc: antoniogamiz self-assigned Spin off Perl6::Documentable github.com/perl6/doc/issues/1937
sena_kun I won't say some poor excuses like "I never encountered this issue", but yes, you are right in this regard. I know other places like this, but I guess this is where waterbed of complexity goes in. 09:12
09:16 Sgeo__ left
robertle_ yeah, and that "lexical purity" of course does not sit 100% in the perl world where it's more like a spoken language. so if you rename $sugar to $rat-poison, it perhaps ought to change something somewhere :) 09:16
09:17 Sgeo__ joined
sena_kun well, at the very least, I think, in future we can warn/mark as error it in Comma 09:17
so it becomes just yet another silly thing with a quickfix like "Expand the pair literal". :) 09:18
nepugia hmmm.... there is a jvm to llvm frontend, and rakudo can target jvm right, so can i make native executables with this i wonder :3 09:19
sena_kun you always can try. :) 09:24
nepugia I might just do that later :)

ugexe: The problem with moar-bleed building a release version is fixed. 13:27

patrickb Xliff: I think I don't understand the question. What's old-style, what's new-style? 13:35
Xliff This is nqp version 2019.03-193-gb19216a8f <-- old style version 13:37
patrickb: This is Rakudo version 2019.03.1-477-ge35c61550 <- also old style version 13:38
patrickb: This is Rakudo version 2019.03.1 <- Release (?) style version, which I am getting when I compile via WSL 13:39
patrickb Xliff: Yes, that's how a release looks.
Xliff OK. So the invocation has gone from...
"rakudobrew build moar" 13:40
to "rakudobrew build moar master"
13:41 zakharyas left
patrickb Xliff: When using rakudobrew and not specifying a version it since lately builds the latest release not master anymore. 13:42
Xliff: So just as you said, to build master one now has to use "rakudobrew build moar master"
Xliff Right. That's a change of behavior. Just wanted to make sure that was the PROPER behavior

lizmat this is opposed to epoch seconds, I guess 14:42

though I still would like to know why my code is not working 15:23
it's a weird error mm
15:26 meylor left
antoniogamiz mm it has to be something related to Pod::Load because it works if I dont use it xd 15:27
15:28 meylor joined
sena_kun Pod::Load uses a Pod decoder which isn't mean to be used in multi-threaded environment, so it complains... 15:28
antoniogamiz agh 15:29
sena_kun I have a feeling it is worth a rakudo ticket.
MasterDuke antoniogamiz: maybe you could wrap where you use Pod::Load in a `protect`?
antoniogamiz mmm I dont know what a protect is, let me check it
sena_kun I was able to make it parallel with gist.github.com/Altai-man/bb7a5773...bbfc61af45 but it is ugly and the decoder exception still occurs sometimes, so it is my luck and not a real solution 15:30
antoniogamiz MasterDuke: I'm seeing that protects are used with Async, but I'm using .race
MasterDuke docs.perl6.org/routine/protect
well, you can `protect` anything (though with varying usefullness) 15:31
sena_kun github.com/MoarVM/MoarVM/blob/1049...der.c#L114 15:32
I think you can ask e.g. samcv about this, and, well, #moarvm channel in general
antoniogamiz I will go there and try protect too! thanks a lot for your time, sena and masterduke! 15:33

antoniogamiz MasterDuke: your solution works but it takes the same time :/ 15:41
MasterDuke antoniogamiz: yeah, all the real work is being done in `load()`, but the `protect` is serializing it so the parallelization won't help much 15:43

Kaiepi the third perl weekly challenge is dead simple to do fpaste.scsys.co.uk/585130 19:10
timotimo antoniogamiz: hey, you asked about the decoder single user mode thing
antoniogamiz: you'll just™ have to make one instance per thread (or task) of whatever is holding on to the decoder object; worst case, the module you're using has to allow you to supply your own decoder instances 19:11
or do we actually allocate one decoder for every instance of wanting to decode something anyway ...
antoniogamiz timotimo: mmmmmm I will try it right now! 19:12
timotimo i'd need more info to find out what exactly is going wrong (perhaps even with --ll-exception)
antoniogamiz I'm using Pod::Load, you can check it out here => github.com/JJ/p6-pod-load 19:13
and this is the code gist.github.com/antoniogamiz/c09b1...cbf6f1eb4d
timotimo hm. is it the .slurp in the last multi sub load that does it? 19:14
antoniogamiz you need to have the doc folder in perl6/doc repository
timotimo i mean, it shouldn't be, i don't think
antoniogamiz timotimo: ??
I have used this @files.race(batch => 8).map({ use Pod::Load; load($_); }); 19:15
but it looks like it does not create another instance
timotimo you'll have to try to get a stack trace 19:17
antoniogamiz sena_kun told me that the error was defined here => github.com/MoarVM/MoarVM/blob/1049...der.c#L114 19:18
I still have to learn how to make a stack trace in perl6 xd
suggestions?

java couldn't execute that jar file though :/

synopsebot_ Link: doc.perl6.org/language/unicode_entry
kawaii nepugia: thanks for the tip, I will check it out and see what I can do :) 23:08
timotimo yeah, i think you can't run jar files that rakudo spits out directly 23:10
similar to .moarvm files you create with rakudo on moar
nepugia I hope that the .class file inside the .jar is usefull to me
kawaii timotimo: is that something we're working towards? 23:11
timotimo though we have a GSoC project going that would make linked-together elf files out of moarvm byetcode
kawaii IIRC there was another project to make perl 6 binaries that were portable
timotimo: ah yes
that sounds familiar
got any documentation on it?
23:11 dolmen joined
timotimo there's a blog with progress reports 23:11
nepugia is cloning llvm to try to use the java frontend with the .class files to creat a compiled hello world 23:12
timotimo yakshavingcream.blogspot.com/2019/06/
kawaii thank you!
timotimo the .class files definitely have some "java code" in them, i.e. rakudo-on-jvm spits out java bytecode 23:13
kawaii I'm curious what the point of these jar files are then if they can't be executed _by Java_? 23:16
Apparently the performance is poor _according to Google_
nepugia how do you measure the performance of what you cannot execute?
timotimo yeah, rakudo-on-jvm isn't very good, or do you mean llvm's java frontend?
kawaii nepugia: exactly, not sure how these people can claim it's 'not fast' when no one I know actually got java to run one of these jar files 23:17
timotimo: any documentation for getting the mbc backend up and running? :) 23:18
timotimo why do you need to run the jar files directly?
kawaii timotimo: I'm just curious about cross-platform within perl 6 :)
timotimo i mean .moarvm files are also cross-platform 23:19
nepugia aslong as you can get moarvm onto the platform, i would assume that java has conquered more platforms yet 23:20
timotimo and rakudo-jvm is also cross-platform, isn't it?
probably
kawaii right but you _need_ Java or MoarVM installed on the target to make use of these
timotimo we depend on libuv, among other things
kawaii unlike a Go binary, which just runs anywhere
timotimo wait, you can build a go tool for linux and run it on a mac?
kawaii AFAIK 23:21
timotimo i was about to say "and run it on windows" but windows is a linux nowadays anyway
kawaii Go and Rust are more or less entirely cross-platform native
timotimo how do they do it
nepugia that's not how ELF files work :)
you can compile it for mac though i suppose
timotimo: the wsl 2.0 will suprise you then, it beeing /literally/ linux... running under their hypervisor 23:22
timotimo there's FatELF, which i don't think took off at all, but that's theoretically compatible with both a 32bit and a 64bit linux with just a single file
kawaii I don't use either of those languages, I did a few hello world things in Rust and the compiler spat out executables for both Linux and Windows (an actual exe!)
timotimo it doesn't surprise me, i know about it :)
oh
i thought you were claiming the same file just runs on both windows and linux and mac or something
kawaii I _assume_ the Linux one would probably work on a Mac 23:23
nepugia kawaii: how so?
timotimo i mean i guess if you build the .exe and the linux machine has the wine binfmt thing installed it'll also just work by ./-ing it
nepugia does macos have a linuxulator too?
timotimo i'm more than just a little annoyed there's no haiku port of libuv :( 23:25
nepugia no perl6 on haiku? :(
timotimo but i haven't used haiku for more than half an hour in total so far, so it's not that bad
i'm not aware of anybody trying moarvm on reactos, that could be fun 23:26
