lucasb REMINDER to *Advent of Code* players: Join the Perl6ers leaderboard! The code is 169430-b1c331b2 00:01
Next task opens in 5 hours. I'll be asleep by then. Good luck! :) 00:02
mornfall marcoonroad: there's a profiler (--profile), so that could be a good start (it's not exactly cheap though)
Kaiepi travis-ci.org/Kaiepi/p6-Net-Telnet.../450655537 00:03
why would the connection be closed before anything closes it? there aren't any race conditions in my code afaik 00:04
i've only ever seen this happen on mac 00:06
mornfall it's the '18 not ok' what you mean?
Kaiepi yeah 00:07
buggable New CPAN upload: Terminal-Spinners-1.3.0.tar.gz by RYNIX modules.perl6.org/dist/Terminal::Sp...cpan:RYNIX
Kaiepi waaait a minute 00:08
never mind there is a race condition lol
good thing it's just in the test file 00:10
mornfall yeah, the $client.close can happen any time 00:11
(with respect to the checks)
async is hard, even though the language support is pretty okay 00:12
also that sleep :p 00:14
Kaiepi yeah, that sometimes fails on mac for whatever reason 00:15
mornfall (makes you wonder whether 'closed' shouldn't rather be a supply...)
(or perhaps a promise, that'd make more sense?) 00:17
Kaiepi i'll try that out once i fix the other issue with the test
mornfall which other issue? 00:18
Kaiepi the race condition with .close
mornfall well, making .closed a promise is a fix for that? 00:19
SmokeMachine marcoonroad: I don’t know about test coverage... but you told about fuzzy test... there is it: github.com/FCO/Test-Fuzz
mornfall the race is going to be really hard to fix otherwise?
you'll have to make an auxilliary promise for the test, i guess
(so instead of $client.close, you say fulfill a $can-close, and await that and then close?) 00:20

00:22 atweiden-air joined 00:23 p6bannerbot sets mode: +v atweiden-air
Kaiepi yeah i'm used to node, where i'd be able to get away with making .closed just a straight Boolean without any issues unless libuv interferes 00:24
MasterDuke marcoonroad: hm, not sure what's up with the bot (it should link to a gist of the coverage log), but there are the MVM_COVERAGE_LOG and MVM_COVERAGE_CONTROL env vars you could play with
mornfall i know nothing about node... is it single-threaded with explicit coroutines?
00:24 w_richard_w left
Kaiepi it's single threaded apart from io stuff, which is handled under the hood 00:25
the async stuff is handled in one thread on the event loop
mornfall io stuff is done in the typical async fashion, no?
like python asyncio
that's the whole point of libuv, anyway
IO event loops
and lots of trampolining around :) 00:26
Kaiepi i've never used asyncio in python
you write the io stuff like you would anything else in node, but the async stuff is handled in the background
00:26 w_richard_w joined
mornfall asyncio runs in a single thread too, and your code can only be interrupted at an 'await' 00:26
Kaiepi ohh
in node it's done through callbacks instead of promises 00:27
mornfall eww
Kaiepi yeah it's really easy to write spaghetti in node
00:27 p6bannerbot sets mode: +v w_richard_w
mornfall the so-called 'native coroutines' in python (what you are supposed to use with asyncio) are kinda crippled, but they are a hell lot better than a callback hell 00:29
(they only thing they can do is 'await' another native coroutine... the only way to actually yield is to call one of the asyncio/event-loop provided methods, which jump down to the event loop trampoline and other 'threads' get to run) 00:31
(the good thing about this is that you don't run into race conditions nearly as easily... the bad thing is that you can only use one core to run the program)
marcoonroad nodejs runs blocking io (io unable to be async) in another thread, but it is in far rare cases, i dunno. it means that node is not single threaded, but double-threaded depending on the sort of OS interaction which you perform 00:33
i work with nodejs on my daily job, and sometimes when dependencies break due updates, it makes me not much happy in such times 00:35
mornfall i wouldn't expect any modern system to mandate blocking io on anything... perhaps calls into C modules would be handled that way though?
marcoonroad the ideal place to call c modules is in another process. this is how they perform unit tests on c, and this is erlang/elixir work with c bindings while maintaining fault-tolerance. you know, segmentation faul$62272##@*? 00:36
thanks SmokeMachine and MasterDuke o/ 00:38
SmokeMachine I think test coverage could be done with `trace` 00:41
00:42 lichtkind left
SmokeMachine There are no documentation for trace?! Os it called trace? 00:43
00:43 sena_kun left
MasterDuke samcv++ i think has automated some coverage reports for the nqp tests 00:43

timotimo marcoonroad: if you're still interested in coverage, you can check the env var for moarvm MVM_COVERAGE_LOG 02:25
moar --help for the win 02:26
marcoonroad it would fit better as moar --sos :) 02:28

SmokeMachine lucasb: what's that golf you guys were playing? 14:01
lucasb SmokeMachine: adventofcode.com/
mornfall tbrowder: can it be a repo of markdown files? :) 14:02
a script could probably publish that even to wordpress, if need be 14:03
14:10 yqt left
tbrowder mornfall: actually, i would prefer that since it would make it easier for web edits and seeing a rendered view by github (although it wouldn’t be the published view). i think md should provide enough formatting features to satisfy most of us (i hope). 14:17
as to second point, as possibly an interim solution looking at using Wordpress’s API to do that. 14:18
tobs` tbrowder: comments are also desirable
lucasb tbrowder: may I persuade you to "gem install jekyll" and play with it? :) jekyllrb.com/ 14:19
Kaiepi what's the code for the perl 6 leaderboard on advent of code? 14:20
tbrowder maybe, is that what worpress uses?
mornfall lucasb: what'd be the point of that? there's a very definite bound on number of articles, using jekyll for that sounds like substantial overkill?
lucasb Kaiepi: 169430-b1c331b2 14:21
14:21 tmtvl joined
Kaiepi thanks 14:21
tbrowder tobs: agreed. not so easy to do, maybe wp api is the way to go...
tobs` and as I've said before: drafting, reviewing, editing the advent posts completely in the open would sound odd to me, as it is supposed to be a surprise

tobs` I mean, yes, we're all adults and can spoil the advent calendar for us if we feel like it, but a little barrier would be nice, like a private repository. 14:23

AlexDaniel . 14:23
tbrowder well, as i’ve seen in wp, it let’s one see other posts before publishing (or is that because moritz gave me editor role privs—hard to tell) 14:24
mornfall tobs`: a private repository is also a substantial hurdle for contributors
Kaiepi first part of the first day of advent of code was pretty painless hastebin.com/hipejecine.pl 14:25
i wonder if there's a shorter way to do it
14:25 zakharyas joined 14:26 daxim joined, p6bannerbot sets mode: +v zakharyas, p6bannerbot sets mode: +v daxim
tbrowder the p5 folks seem to have a process where you have to submit early and a committee approves it 14:26
lucasb Kaiepi: say [+] lines>>.Int :-) 14:27
tobs` mornfall: what kind of contributors do you mean? Article writers or casual proof readers? For the latter it's kind of my point to make it an obstacle, as bad as that sounds.
Kaiepi ah
lucasb Kaiepi: I like to feed the input file in the command line "prog < input"
mornfall tobs`: to be honest, the quality of text has not been very high so far -- discouraging proofreading further doesn't sound like the right direction to me 14:28
having a few semi-pro writers as copy-editors on the team would probably help a lot, but an entry barrier virtually ensures that it's not going to happen? 14:30
dunno, just my impression (fwiw, i would contribute via copy-editing if it the process for that would be simple enough) 14:32
if the process*
14:33 andrew_ joined, p6bannerbot sets mode: +v andrew_, andrew_ left
tobs` mornfall: what I mean is, if we have an open repository and every day the next person announces their draft here looking for opinions, at least half the channel will have casually read some version of the article before it's even time to open that little door on the advent calendar. Only this effect is what I'd not like to encourage. 14:36
mornfall tobs`: that will largely depend on whether there is or isn't a test audience other than #perl6, is that not so? 14:37
so perhaps a thing as simple as having #perl6advent would fix your concern? 14:38

hahainternet so i've got a very odd bug here where i have two identical range constructions that are mapped inside an existing map 14:46
the second one always fails unless it's assigned to a variable
in which case it only works if it's assigned to a list(or array i forget the specifics)
i'll try and work up a little test case 14:47

ufobat is there a way to have one or another type in one method signature, like method foo(Str|Blob $data) { ... } 14:56
tobs` hahainternet: it works here in my 2018.10 repl (usually it's the other way around)
ufobat do i need to write method foo(Any $data where * ~~ Str|Blob)? 14:57
hahainternet tobs`: i don't really know how to use bisectable6 :) 14:59
bisectable6: help
bisectable6 hahainternet, Like this: bisectable6: old=2015.12 new=HEAD exit 1 if (^∞).grep({ last })[5] // 0 == 4 # See wiki for more examples: github.com/perl6/whateverable/wiki/Bisectable

camelia ok 1 -

hahainternet tobs`: can you tell me the commit id of a working commit? lets try some other commands the wiki recommends
6c: (^1).map: { (^1).map({say "Hello $_"}); (^1).map({say "Goodbye $_"}); };
lol 15:00
tobs` ufobat: you can use a subset
committable6 hahainternet, ¦6c (35 commits): «Hello 0␤»
tobs` hahainternet: my $*PERL.compiler.version is exactly v2018.10 (and I'm otherwise pretty sure too that I only install the monthly releases) 15:01
ufobat subset StrOrBlob of Cool where * ~~ Str|Blob
like that?
hahainternet tobs`: and it prints both for you? cause none of these versions seem to want to 15:02
tobs` ufobat: I made an example 3 minutes ago
but yes :)
ufobat ah sorry didn't see it, thanks :-)
oh you can leave out the `* ~~` part, thats fancy 15:03
tobs` hahainternet: it doesn't print under `perl6 -e`, but it does in the REPL
15:04 daxim left
tobs` but IME, when they both disagree, the REPL is the one with buggy-looking behaviour 15:05
hahainternet tobs`: how bizarre
tobs` hahainternet: is it at least the same on your system? 15:09
hahainternet tobs`: just checking
tobs`: it is, repl prints both and the result 15:10
-e doesn't print both
i notice if i assign the second one to an array, it tends to work
m: (^1).map: { (^1).map({say "Hello $_"}); my @a=(^1).map({say "Goodbye $_"}); };
camelia Hello 0
Goodbye 0
hahainternet m: (^1).map: { (^1).map({say "Hello $_"}); my $a=(^1).map({say "Goodbye $_"}); };

tobs` lucasb: but my type is called A::B and it's (otherwise) not necessary to export it. If I want coercers in function signatures to work, it _has_ to be method A::B as far as I know. 15:36
lucasb yeah, you are correct 15:37
hahainternet SmokeMachine: yeah i'm really not sure what causes that, if you or lucasb can figure it out please lmk
lucasb tobs`: in a imaginary language, the coercer method would me Mu.to(Something) 15:38
obj.to(Array), obj.to(Foo::Bar), etc
multi method to(Foo::Bar) {...}, etc. :-)
I think this would give a clear idea of what the possible coercions are. just query the signatures of the .to(Something) method 15:40
anyway... just design ideas :-) unrelated to P6

which you can figure out using moarvm's coverage tool! 17:55
hahainternet heh interesting, trying to use set operators on 'my Set $whatever' seems to infinite loop somewhere inside p6
'my $whatever = set()' just fine though
i assume some initialisation i did not fully do, but a bit surprising

ufobat afaik the TWEAK must match the possible parameters, it must be inheritance and role composition aware as well, right? so i'd say haveing a StrictClass wont work 19:26
Sharparam is there a (built-in) way to have a default value "factory" for hashes similar to ruby's `Hash.new { |h, k| h[k] = value }`? (to prevent things like the same array instance being set for every key) 19:30

timotimo that's not what you meant, right?
Skarsnik: i'm not entirely sure if i'll be able to make mine work, really
Skarsnik I am like 30% done with what I wanted to do xD 21:00
timotimo i wonder if day 14 and 15 are accidentally the same talk?
"designing" and "building" a space ship with perl 6
sena_kun no
but, well.
that's mine. 21:01
timotimo oh, is that you?
sena_kun yeah
my another nick. :P
sena_kun apparently confuses too much people
anyway
21:02 kensanata joined, p6bannerbot sets mode: +v kensanata
sena_kun I had one already done and second one being ready in my head. but then I continued to use this thing. and it turned out to be completely mess, my "architecture" is so horrible I'd like to jump out of the window(gladly, I live on second floor, no worries). Still, I hope, I will make it in time. With re-designing pretty everything. But if one spot will be taken, I am not sure it'll hurt. 21:03
Sharparam SmokeMachine: hm?
sena_kun s/too much people/people too much/
ufobat SmokeMachine, are you going to make a perl6 module out of it? 21:04
Skarsnik I could do a Usb2Snes module but nobody aside me will use that xD 21:06
timotimo what does that do? is it for controllers? 21:07
Skarsnik btw is there a plan to have an individual module for websocket client or Cro::ws does not need the whole Cro
SmokeMachine ufobat: I was not thinking of it... too many modules on the list...
sena_kun Skarsnik, no. it uses cro-http client/server inside, it's just a tiny wrapper. 21:08
Skarsnik, or please define what do you mean by "whole Cro". Core is essential, http is used inside, what else?
SmokeMachine ufobat: will you? 21:09
ufobat SmokeMachine, if you want me to make a module ot of it, i could do it. But my Meta programming skills are so low that i probably can not improve it any further
Skarsnik Usb2snes is a firmware for a sd2snes (a cartridge with a flash cart slot for snes) that allow you to use the usb port to communicate with it. Then you have a websocket server on top of that to expose the device to multiple client (since only one app can use a usb port otherwise). so a Usb2snes module will be a client for the ws part 21:10
this allow stuff like sharing ammunition/healt/item on some game. or to upload rom directly on the device ^^ 21:11
timotimo oooh, it's like that plugin for that emulator that mcclure made
SmokeMachine ufobat: you can use that code if you want... and there are a lot of people here that could help you... :)
timotimo i mean the plugin was made by mcclure, i don't remember what emulator it was and who made that
ufobat allright, i'll create a module and send a mail to the perl6 mailing list in order to look for help and feedback 21:12
Skarsnik I wrote a replacement websocket that allow to use other stuff like some emulator and the Snes Classic
*websocket server 21:13
SmokeMachine ufobat: but what do you want to add to the module?
ufobat StrictClass ?
SmokeMachine ufobat: yes... what that that code doesn't do yet? 21:14
timotimo Skarsnik: "some emulator" :D
Skarsnik RetroArch and a special patched snes9x 21:15
masak pmurias: are you suggesting what Perl 6 has is _not_ gradual typing? do you have an example of a language that does have it?
yoleaux 16:59Z <jmerelo> masak: you have Dec 5th in the Advent scheduler. Is it ready?
ufobat i dont know, maybe nothing. but if you compare to MooseX::StrictContructor is sufficient to load the module, maybe there is more pretty way to achive that your class is a strict class
right now you need to do `does StrictClass` right?
masak yoleaux: how do I reply back to jmerelo using you? 21:16
timotimo you can have that module export a "sclass" exporthow that adds the StrictClass by itself
ufobat idk what people want, for me it is already exactly what i need
timotimo masak: you can just ".tell jmerelo blah"
SmokeMachine ufobat: yes...
sena_kun masak, `.tell $nickname $message`
masak .tell it's not ready, but I'm still planning to write it before the 5th. today is the 3rd. hope that works ;)
yoleaux masak: What kind of a name is "it's"?!
ufobat but, not knowing how to improve it makes me a bad module owner
masak .tell jmerelo it's not ready, but I'm still planning to write it before the 5th. today is the 3rd. hope that works ;)
yoleaux masak: I'll pass your message to jmerelo.
masak by my calculations, I have more than a day to write it. 21:17
timotimo masak: well, hopefully you can squeeze in one or two review-refinement cycles :)
masak yes, good point
Skarsnik unrelated, could we have a pragam that enforce compilation to check method type?
masak I'll aim for having it ready mid-tomorrow-night, European time 21:18
timotimo well, in theory yeah, you just have to come up with a scheme of restrictions that you'd like
masak Skarsnik: "check method type"?
Skarsnik because 99% of the time you don't add new method dynamicly
timotimo masak: i assume something like C++'s virtual method restrictions
21:18 Xliff joined
masak ah. 21:18
timotimo oh, i think i was wrong
Skarsnik no, more like my Foo $a; $a.lsllkd; should not compile 21:19
21:19 p6bannerbot sets mode: +v Xliff
timotimo ah 21:19
masak only if $a is initialized in that scope
otherwise, it could be a subclass which has that method 21:20
cf "exact type"
timotimo i think that's an accepted trade-off
Skarsnik The type is know for this example
SmokeMachine ufobat: that can help you to improve your skills? :)
masak timotimo: sure, but in that case, it's a narrower language than Perl 6.
Skarsnik I don't expect the compiler to figure for code like my $a = somerandomsub(); $a.piko;
timotimo indeed 21:21
that's why Skarsnik wants a pragma :)
ufobat SmokeMachine, :D ha!
Skarsnik yes, because I know you COULD add method at runtime
but 99% you never do that
masak speak for yourself :P
masak .oO( most people only use 1% of the raw power of their Perl 6 ) 21:22
masak .oO( my code is so dynamic, even the methods added at runtime have methods added at runtime! ) 21:23
timotimo no need to add a method at runtime, can also just have a method defined in a subclass
Skarsnik: how do you feel about checking argument types as well? 21:24
Skarsnik yes that too
timotimo that'll be even more fun :) 21:25
Skarsnik I mean when I explicitly use type I kinda expect to have the compiler for a maximum of stuff he can solve
timotimo but yeah, i think you could do it with a slang.
do you also want subclasses to be restricted in what methods they can install under the same name?
masak surely arguments must be allowed to be subtypes? 21:26
timotimo i'd expect that
masak otherwise you can't bind an Int argument to a Real parameter
Skarsnik related, can we now finally add overload in a subclass for no multi method in the base class? 21:27
timotimo what'd be the difference between putting a proto or only method in the subclass? 21:28
Skarsnik I had a real case use for that, but I can remember

patrickb goes to bed 21:31
'night everyone.
21:31 patrickb left
Skarsnik well since the subclass herit the method from the baseclass this should work 21:32

timotimo behold
Xliff timotimo: And what is this greatness? 21:46
timotimo well, Skarsnik's problem was:
Skarsnik it's just a workaround. It should work out of the box xD
timotimo if the base class defines a method without "multi", the subclass will override it with whatever you put into the subclass, even if it's a multi
so if you want to have only methods as candidates to your new multi, you can use this trait on the subclass 21:47
and it will put the methods back in for you
Skarsnik The signature is not the same, I don't even get why it replace it
21:47 neteng1198s joined, p6bannerbot sets mode: +v neteng1198s
timotimo that's the difference between only and multi, Skarsnik :P 21:47
Skarsnik but the issue you cannot put multi for one method on the base class 21:48
so etheir way, it's always hacky
timotimo you're going against the wishes of the base class, of course it won't just happen by itself with not a single bit of work :) 21:49
neteng1198s User inputs motorcycles and I have an array @motorcycles = qw(ducati,honda,yamaha). It would then print this array. Is this possible?
timotimo neteng1198s: if you use qw you don't put comma in between :) 21:50
21:50 Sound left
timotimo do you mean when the user inputs "motorcycles" your code will look if a variable named "@motorcycles" exists and outputs that? 21:50
neteng1198s timotimo: sorry typed wrong .... but you get the gist
Skarsnik timotimo, it work for most OO language? since the full signature is the definition of the method, not just the name
neteng1198s yes

Skarsnik hm
timotimo that was the same code again :P
Skarsnik I forget to close the " in the first 21:52
timotimo m: my @motorcycles = <ducati honda yamaha>; my @animals = <cat banana>; my $userinput = "motorcycles"; say @::($userinput).perl
camelia ["ducati", "honda", "yamaha"]
timotimo m: my @motorcycles = <ducati honda yamaha>; my @animals = <cat banana>; my $userinput = "animals"; say @::($userinput).perl
camelia ["cat", "banana"]
Skarsnik oh it's with ()
timotimo it's telling you to try $::("hello") :)

timotimo neteng1198s: just to be sure, you're working with perl6, right? not perl5? 21:53
neteng1198s no I'm current on 5.10 ATM
timotimo ah, in that case the code i showed you won't work
Skarsnik this dumb "thing" is used in Http::UA cookies
timotimo since perl6 is the very different rewrite that is developed at the same time as perl5 is 21:54
eater m: my $i = "no"; multi trait_mod:<is> (Variable $a, :$b) { $i = $b; dd $i; }; my $x is b<yes>; dd $i; 21:55
camelia Str $i = "yes"
Str $i = "no"
Skarsnik Anyways, I think that just the name is used for a method overload is a bug xD
eater How do I make sure $i stays yes? :o
Skarsnik my $i is ro? 21:56
timotimo eater: i'm not entirely sure what the problem is 21:57
eater I'm trying to change a variable in trait_mod, but it seems to get reset to the original value 21:58
timotimo it's a compile-time / run-time thing
Skarsnik trait are compile time
timotimo my $i = "no" actually compiles to an assignment
eater I guessed so
is there a way to work around that?
timotimo should be able to change the default i suppose?
m: my $i; say $i.VAR.^methods 21:59
camelia (<anon> <anon> new name of default dynamic WHICH BUILDALL)

timotimo well, not like that
neteng1198s ok.... is that possible in 5?
timotimo neteng1198s: yes, it is for sure
22:00 ryn1x joined
timotimo stackoverflow.com/questions/628565...her-scalar - this might be the right thing for you 22:00
22:00 p6bannerbot sets mode: +v ryn1x
timotimo though the answers are pretty don't-do-that, so perhaps you can use a hash of arrayrefs instead 22:01
so i guess like my %topics = motorcycles => \[qw( yamaha honda ducati )], animals => \[qw( cat banana )]; my $userinput = "animals"; print @$topics{$userinput} 22:02
that's probably not valid perl5, i haven't coded perl5 much 22:03
but i'm sure you get the idea
good luck, neteng1198s! perhaps try #perl on this same network (or is it ##perl?)
neteng1198s Thanks timotimo 22:05
going to try in a minute
SmokeMachine timotimo: [] already return a ref
timotimo oh, it does? cool.

neteng1198s wonderful lol 22:24
does this means lots of scripts will break when I finally upgrade? 22:25
SmokeMachine neteng1198s: no, because its not the next version... it really is a different language...
neteng1198s any recommended reading 22:26

timotimo we have the perl5 to perl6 documents on the docs page 22:40
docs.perl6.org/language.html#___top - second section, the "migration guides" has them
if you want to "upgrade" (though it's really a sidegrade i guess?) your code from perl5 to perl6, you can do it on a module-by-module basis and use Inline::Perl5 on the perl6 side or Inline::Perl6 on the perl5 side 22:43
