pilne i am getting quite impatient to see if the rakudostar installer gets updated for either of the big .07 rakudo upgrades, will i end up regretting installing 2019.3? 00:49
(windows version) 00:50
timotimo i don't see a reason to regret the installation 01:04
pilne and when a new one comes out, it's as easy as an uninstall then fresh? anything to keep note of to backup before? 01:13
timotimo hm, i don't know where on windows installed modules will be put; but you can get output for that with this code: 01:15
m: .say for $*REPO.repo-chain
camelia inst#/home/camelia/.perl6
inst#/home/camelia/rakudo-m-inst-1/share/perl6/site
inst#/home/camelia/rakudo-m-inst-1/share/perl6/vendor
inst#/home/camelia/rakudo-m-inst-1/share/perl6/core
ap#
nqp#
perl5#
timotimo that's perhaps something to keep around, even though updating rakudo will invalidate the precompilation results and we don't actually have something to delete precomp stuff i don't think 01:16
pilne that's fine, i really just need a list of what i have, not the actual code (i'll have my own code setup locally, should probably look into a git for windoze solution) 01:40
and will i be missing out using vscode over atom? 01:41
something tells me i'll go to comma soon™ but not quite ready for something as heavy as an intellij inspired solution quite yet (as i've never gotten along with them in general in the past). 01:44
irced anyone know of a perl6 direct or indirect way to change an environment variable so that it persists after the script ends? (specifically in BASH) 01:50
Elronnd irced: no, you have to set it from within bash 02:02
(I mean, I could imagine a super convoluted situation where you have a perl6 instance that spawns a bash, and opens up a socket so child scripts can ask it to change env vars. But that's really not worth it.) 02:03
irced Elronnd: cool. i figured it would otherwise require low level maybe native call hacks or like what you said.
Elronnd: thanks for your input 02:04
Elronnd in general, if you are a script being controlled by someone else, you cannot change anything about them

timotimo ^- wants Supplier::Preserving 02:06
Xliff Is that the only way to make it work?
m: my $S = Supplier::Preserving.new; my $s = $S.Supply; $S.emit(1) for ^4; $s.tap({ say "Hi!" }); sleep 5;
timotimo it's literally the raison dêtre for that class
camelia Hi!
Hi!
Hi!
Hi!
Xliff m: my $S = Supplier::Preserving.new; my $s = $S.Supply; $S.emit(1) for ^4; $s.stable(0.5).tap({ say "Hi!" }); sleep 5;
camelia Hi!
Xliff I'm implementing my events in GTKPlus using just a supplier tho. 02:07
Should those be ::Preserving now? 02:08
irced sacré bleu!
timotimo not necessarily
irced just wanted to show off unicode accents.
timotimo could also have supply blocks, such that they set up the connections at the gtk-side of things when an actual tap happens
Xliff m: use v6.c;my $S = Supplier.new; my $s = $S.Supply; $S.emit(1) for ^4; $s.tap({ say "Hi!" }); sleep 5;
camelia ( no output )
timotimo then it'll actually create one connection for every tap that exists
Xliff Well fahrfignugen!
timotimo unless you return the result of .share on the Supply
good night! 02:09
Xliff timotimo: I may need you to look at event code, then!
timotimo: I will lasso you, if I have to pardnah! 02:10
timotimo nah
:
:P
Xliff yah 02:11
:p
timotimo i believe in the you that believes in yourself
Xliff i believe in my lasso. 02:13
I am about to corral m'self a bed. 02:14

kentnl I'm doing vendor stuff for moarvm, upgrading from moarvm 2019.07 to 2019.07.1 results in moarvm no-longer installing libmoar.so, is this the right place to hope for somebody to explain why? :) 04:02
kentnl couldn't spot anything in the commit diff that explained it 04:03
kentnl the most likely candidate was github.com/MoarVM/MoarVM/commit/25...53a04a6e11 , but it doesn't apply here, because we applied that patch on 2019.07 04:04
irced kentnl: sit tight or perhaps ask again earlier next evening. i know there are some devs who can speak to the builds but maybe not this instant. 04:07
kentnl it may actually be related to a similar problem where libmoar is installed to /lib64/ instead of /usr/lib64
kentnl did change something in his tooling between these versions, I just didn't expect there to be a change that affected that 04:08
kentnl will have to test that 04:08
goddamn, it *is* something in tooling doing something funky with /lib64/ 04:13
kentnl nvm, it is 100% on our side, I get to blame somebody else for doing something wrong in the first place. 04:26
irced kentnl: cool
kentnl: and not so cool
kentnl 90% of the time, you don't realise the real problem until you ask somebody about what you think the problem is :(
irced kentnl: cool

read: Connection reset by peer
AlexDaniel which works great, as you can see
timotimo: do you have access to camelia's machine? 15:16
timotimo: because it is stuck
chloekek timotimo: you have to restart programs that use it, usually. 15:17
timotimo: XCompose is read by every program separately, not by a daemon.
2019 won't be the year of the Linux desktop. 15:18
AlexDaniel well, last time I was changing my xcompose stuff I had to restart X, so…
I hope it is really better now and you *just* have to restart every program instead…
timotimo i've restarted my terminal emulator, tried a different one, tried setting GTK_IM_MODULE to xim before starting gnome-terminal or xfce4-terminal, tried terminology 15:19
chloekek gnome-terminal shares one process for all windows.
You have to close all gnome-terminal terminals.
timotimo i killed the gnome-terminal-server process after closing all terminals
AlexDaniel or just restart… :) 15:20
chloekek At home I use Sakura and it works if I start a new terminal after changing .XCompose.
timotimo sakura is what, a distro or a terminal emulator?
chloekek Terminal emulator. 15:23
Oh right, probably everything in your stack matters when it comes to X shenanigans. I also use NixOS GNU/Linux distro, i3 window manager, and SDDM display manager. 15:24
timotimo haha, yeah, every little thing can upset the delicate balance that is input on X
chloekek And I can't remember whether it was .xinit, .xinitrc, .xsession, or .xsessionrc that I put my startup commands into. 15:25
Some of them only work on some machines.
timotimo :D
chloekek xkcd.com/963/
timotimo whoa, compose + v + / gives √ 15:26
that rocks
chloekek p6: sub infix:<√>($b, $x) { $x ** (1 / $b) }; say 3 √ 27 15:27
camelia 3
chloekek My .XCompose is simple, it has [[ for ｢ and ]] for ｣ :) 15:28
timotimo i want that 15:29
timotimo aaaaah 15:38
in the xfce4 control center thingie for "Keyboard", i can type compose+*+i to get ι
wait
that also works in my terminal now
maybe opening that tool was all i had to do to make things work, lol
now i have ⊏⊐ on the combinations you just mentioned 15:43
which i think is also kind of cool
unicodable6: ⊏⊐ 15:44
unicodable6 timotimo, U+228F SQUARE IMAGE OF [Sm] (⊏)
timotimo, U+2290 SQUARE ORIGINAL OF [Sm] (⊐)
timotimo what :) :)
i haven't a clue where that comes from
but i like how in my current font it forms one closed shape
timotimo i also have ⬚ and ⌷ 15:44
unicodable6: ⬚⌷ 15:45
unicodable6 timotimo, U+2B1A DOTTED SQUARE [So] (⬚)
timotimo, U+2337 APL FUNCTIONAL SYMBOL SQUISH QUAD [So] (⌷)
timotimo squish quad!
that is an amazing name
AlexDaniel m: say Q⊏hello world⊐
camelia hello world
timotimo heck yeah 15:46
antoniogamiz m: "/sth".split("/").elems
camelia ( no output )
antoniogamiz m: say "/sth".split("/").elems
camelia 2
AlexDaniel timotimo: `compose s q` should also give √
antoniogamiz how can I avoid that? I mean, get one element only
AlexDaniel depending on your config
timotimo yeah it does
m: say "/sth".split("/", :skip-empty).elems 15:47
camelia 1
timotimo m: say "/sth".split("/", :skip-empty).perl
camelia ("sth",).Seq
antoniogamiz oh nice option
thanks
AlexDaniel timotimo: and if you're using that compose file from github, then `compose * something` is always some math stuff, like `compose * p` is π
hm, or maybe not always… 15:48
timotimo did i paste which file i'm using? 15:49
AlexDaniel not yet
timotimo there's probably only the top result, haha
ah, yes, what i originally wanted was an h and an m that won't confuse perl6's parser when attempted to be used as a postcircumfix
m: sub postcircumfix:<ₕ ₘ>($h, $m) { say "$h hours, $m minutes" }; say 10ₕ3ₘ 15:50

timotimo unicodable6: ľ
unicodable6 timotimo, U+013E LATIN SMALL LETTER L WITH CARON [Ll] (ľ)
timotimo that's beautiful, at least on my font
hum. supposedly i should be able to type multikey ( 1 : 0 0 ) but after (1: it already stops the composition giving nothing 15:53
ha! multi key + multi key + p + o + w 💥 15:54
but it does seem like every sequence of three letters-or-similar ends the thing immediately
AlexDaniel 🕐 15:55
timotimo: iirc I had the same issue, but it works now…
timotimo so i just need to reboot? :P
AlexDaniel maybe wait until your OS is updated… 15:56

Wahnberger hello Folks
timotimo guten tag Herr Wahnberger 15:58
AlexDaniel 🙋 15:58
Xliff 3√27
timotimo that was probably too formal
Xliff Ooh! I have that too. I windows, no less! 15:59
timotimo nice. with wincompose or out of the box for some reason?
Xliff Wincompose
timotimo Wahnberger: you have joined us in a strange moment where we all try out input methods for strange unicode symbols. care to join?
AlexDaniel timotimo: speaking of which, `compose compose o/` and `compose compose \o/`
timotimo that's emoji compose codes, yeah? 16:00
AlexDaniel yeah, if you have them included
actually these may be in the main file…
hmm, nope, where are these coming from then… 16:01
Wahnberger uhm..actually i need to figure out something else :(
AlexDaniel Wahnberger: sure! Just ask
timotimo that's not a problem, we can probably help!
Xliff ⏹️ 16:02
LOL!
Multi+multi+"stop button"
Wahnberger I have build a litte site using Cro and a tiny session management using this: cro.services/docs/http-auth-and-se...ased_login
Xliff ¯\_(ツ)_/¯ 16:03
Hahaha!
AlexDaniel Wahnberger: sounds great so far 16:04
Xliff 💩
Wahnberger all the stuff is working well - but - i want to route then to static pages (just html and JS) .. on those sites i need to know whos is the user but i cant get POST/GET infos by using JS .. anyone an idea how to deal with it?
Xliff I can't get that to come out of wincompose, though. 16:05
Wahnberger of course..thats not really a perl6 question :(
not even really cro but i am not sure :D
btw: I would pay 100 bucks and more for a really handy cro handbook :D 16:06

camelia Hello!
**Hello!**
timotimo i could have explained that much more clearly the first time :S
uzl timotimo: Thanks. I was at the brink of pulling out my hair. 16:13
No problem!
timotimo named arguments only serve for tie-breaking, and since methods accept all nameds by default, both candidates still have the same priority, so which comes first in the source code decides which one wins
or putting an "is default" to boost the priority
uzl timotimo: I was just going to ask why so thanks for the explanation. 16:14
timotimo that smells like an analysis comma could do 16:15
uzl Using Vim at the moment but that's totally something Comma users would benefit from :-) 16:17
AlexDaniel Wahnberger: hmmm, so why can't you do it in cro? 16:23
AlexDaniel Wahnberger: I mean if you just add some routes for static files in cro, wouldn't it just work? 16:23
timotimo the JS in the static app would want to ask the backend if there's a logged-in user i guess? 16:24
if you don't want to modify the file you're delivering to have the user info in it
Wahnberger alex: you cannot route GET parameter to html/JS afaik 16:36
i just found a workaround by using jquery
timotimo: yes the static page need to verify the user at a backend (rest api) 16:37
timotimo on the client-side you can look what the URL is that the user entered or navigated to
that could have the user name the user tried to authenticate as 16:38
of course then the user can just change the URL
Wahnberger oh damn 16:39
I need some holydays 16:40
sorry for the noise :)
timotimo NP :)
Wahnberger I love the Cro libs..thats amazing stuff.. but the documentation is really hard to understand to perl6 beginners .. i would love to see a cro doc from brian de foy 16:47
timotimo hm, yeah, "getting started with cro & perl6" could be a good format for something book-ish 16:48
MasterDuke is there way to get comma not to complain about `nqp::*` calls? 16:58
El_Che so, is someone setting an ad hoc stream from perlcon for the perl6 talks? :) 16:59
antoniogamiz El_Che: I hope someone does 17:00
s/does/is
MasterDuke oh, and i don't remember if i've asked this before, but is there a way to point it at the rakudo source such that go to declaration of perl6 built-ins works? 17:02
AlexDaniel El_Che: that's a great questionE
s/E//
El_Che some people have crazy high volume in their packs 17:04
being a member of the EU all the crazy roaming coast disappear
MasterDuke i'm sorry to miss perlcon. i thought i might be able to make it, but hopefully next year will work out
AlexDaniel El_Che: or if not the stream, what about the recordings… 17:06
AlexDaniel El_Che: I can bring some lightweight equipment with me but I have no idea what's the situation 17:07
El_Che More honestly, by now I would prefer a smaller perl 6 conf. Loosing somewhat intereset in p5 (I still use it though).
AlexDaniel El_Che: like, is there somebody doing the recordings officially?
El_Che AlexDaniel: yes, I read somewhere (tweet) that the sessions will be recorded and uploaded later
AlexDaniel: people from shadowcat always do their own recording as well 17:08
AlexDaniel ok, cool then
El_Che Check with tom bloor if he can upload the p6 somewhere :)
AlexDaniel ahh 17:09
Kaiepi i asked this last night and didn't get an answer so 17:10
how do parametric roles know how many generic types they were declared to use?
in it's meta-class, i mean 17:11
Kaiepi well i can't say its meta-class since there are actually four, so i mean Metamodel::ParametricRoleHOW 17:12
vrurg Kaiepi: what do you mean by that? 17:16
wahnberger timotimo: do you have examples to read? 17:17
timotimo i think the difference between a role like Positional (Positional[Int]) or Rational (Rational[Int, Int])?
wahnberger: for what exactly?
Kaiepi vrurg like, if you declare a role like `role Foo[::T, ::U]` how does it know it needs to be parameterized with two types?
vrurg Kaiepi: it has an associated block which has it's signature which is role parameters. 17:18
wahnberger timotimo: Cro documentation 17:18
Kaiepi hooooooo boy then what i want to do will be a bitch to write, probably 17:19
timotimo besides the cro documentation i don't think i have anything
Kaiepi unless you can use multiple dispatch with the block, but even then...
wahnberger oh..i missread something :D 17:20
vrurg Kaiepi: look at parameterize* family of methods in Role HOWs. For example: my @result := $!candidate.HOW.body_block($!candidate)(|@pos_args, |%!named_args); 17:21
Kaiepi: though I don't remember all the details for now. If I need anything – I pick up my walkingstick and go into the metamodel wilderness. 17:22
timotimo Kaiepi: don't forget any ParametricRoleGroupHOW has .candidates
timotimo m: .perl.say given Rational.^candidates[0].^body_block 17:24
camelia multi sub (::$?CLASS ::::?CLASS Mu $, ::NuT Mu $ = Int, ::DeT Mu $ = { ... }) { #`(Sub|79396720) ... }

camelia :(::$?CLASS ::::?CLASS Mu $, ::NuT Mu $ = Int, ::DeT Mu $ = { ... })
timotimo ::::?CLASS, eh? that's ridiculous :D 17:24

timotimo aye 17:35
El_Che timotimo: twitter.com/shadow_dot_cat/status/...7333385216 17:54
timotimo that's very promising! 17:56
El_Che a nice surprise, as it was supposed to be uploaded later

chloekek Till you can write comments in qqww{ … } 18:30
p6: say qqww{ foo #`(bar) baz }
camelia (foo baz)
timotimo m: say "foobar\qqww[#`( oh another comment )]bazquux" 18:50
camelia foobarbazquux 18:51
timotimo ^ that's wild
Xliff Can you do that with the angled constructor?> 18:55

MasterDuke in comma, is there a way to exclude a particular directory from attempted indexing?
timotimo MasterDuke: i think in any intellij you can set the type of a folder, among other things there's "source code" 19:00
or maybe that's just intellij idea
veesh eh, someone left docs.perl6.org in development mode 19:04
though it's cool that it's on mojolicious
nothing juicy there, but disconcerting 19:05
chloekek p6: ||42 19:46
camelia ( no output )
chloekek The precedence table on docs.perl6.org/language/operators mentions a unary || operator, but I can't find it. 19:47
Kaiepi m: say CORE::{'&prefix:<||>'}:exists 19:53
camelia False
Kaiepi m: say CORE::{'&postfix:<||>'}:exists
camelia False
Kaiepi maybe it's in the grammar 19:54
timotimo m: say(||1 ||2 ||3)
camelia (1)
timotimo m: say(1 ||2 ||3)
camelia 1
timotimo it's a flattening operator i think?
m: say &prefix:<||>
camelia 5===SORRY!5=== Error while compiling <tmp>
Undeclared routine:
prefix:<||> used at line 1. Did you mean 'prefix:<|>', 'prefix:<~^>', 'prefix:<!>', 'prefix:<->'?
chloekek p6: say (|| 1, (2, 3), 4).perl 20:44
camelia (1, (2, 3), 4)
Kaiepi what's the difference between .^type_check and .^accepts_type? 20:48

Aearnus I noticed that too 22:04

AlexDaniel this is more correct, I guess

Kaiepi why doesn't `foo(::T $a --> T)` work? is it because T is still a generic when it type checks the return value or something? 22:51
