MasterDuke .tell sergot fyi, i just created a PR in that gave me a measurable speedup using HTTP::UserAgent to get an HTTPS url 04:35
yoleaux MasterDuke: I'll pass your message to sergot.
Todd__ Hi All, something weird just happened to my perl6:
$ perl6 -v Unhandled exception: While looking for 'ModuleLoader.moarvm': no such file or directory
same message when running "zef" 04:36
MasterDuke Todd__: how did you get/built your perl6? 04:38
Todd__ rakudo-star-0.0.2016.11-1.el7.x86_64
from the rpm
And I did not do anything to since
MasterDuke you're on centos7? 04:40
or rhel7?
Todd__ close. Scieltific Linux 7.3, which rebases centos 04:41
MasterDuke did you use yum to install from a repo or did you download from the rakudo page?
Todd__ yum --enablerepo=epel* install rakudo-star 04:42
that was about two months ago. it has been working since. Would a reinstall screw it up?
MasterDuke well, there's a 2017.01 star, so that repo is out of date
reinstalling should be fine 04:43
Todd__ When I try to reinstall, I get : Installed package rakudo-star-0.0.2016.11-1.el7.x86_64 (from epel-testing) not available 04:44
I wonder if it has been pulled? "whatprovides" still shows it 04:45
MasterDuke if you don't mind installing an rpm directly (and just regular rakudo, not star), El_Che has packages here 04:46
Todd__ what is non-star?
EPEL now has: 04:47
MasterDuke same perl6, just without all the additional modules bundled
Todd__ star had almost no modules anyway that I could tell. I had to zef them all
MasterDuke i.e., you'll probably have to use zef to install the modules yourself
Todd__ do I need to do an uninsall on rakudo-star first 04:48
MasterDuke i don't really know the redhat distros enough to say, but that seems like a good idea 04:49
Todd__ interesting rakudo-start was an 18M package to unbinsall; regular is also 18M 04:51
# perl6 -v This is Rakudo version 2017.02 built on MoarVM version 2017.02 implementing Perl 6.c. 04:52
MasterDuke Todd__: huh, maybe they didn't actually have star in the first place. would explain why you had to zef everything 04:53
buggable: eco sum 04:54
buggable MasterDuke, Found 5 results: String::CRC32, Sum, Business::CreditCard, Concurrent::Iterator, MetaCPAN::Favorite. See
Todd__ makes sense. zef is now broken

MasterDuke might need to ask ugexe, i don't really know zef 05:01
Todd__ not finding how to uninstall zef 05:07
I uninstalled again and deleted /usr/share/perl6; I am updating updatedb; then I will install the one from rakudo-pkg 05:16
ugexe well you could just run it with --/test to disable testing, but rakudo isnt finding your perl6 libs anyway (or it would have found 05:25

Voldenet eh, whenever I recompile perl I tend to just remove ~/.perl and reinstall zef
todd__ and make a link # ln -s /opt/rakudo/bin/perl6 /usr/bin/perl6
Voldenet faster
todd__ I am back and running. zef too. Thank you for all the help.
My guess is that epel screwed up something royalls. SO I think I will stay on nxadm for now 05:42
question. I have #!/usr/bin/perl6 as my first line. so, or course, the rpm and nxadm use different paths. The link cured that. Sounld I not use that as a first line? is there a way to look at both paths in the first line? 05:43

though it's working fine for the other filters so idk. maybe github changed my setting. 06:28

much email. very wow
06:31 ryan_ left, ryan_ joined
samcv lots of silly discussion with the emoji release, people uselessly arguing over what 'recommends' in the technical report means 06:32
Voldenet when I was younger I thought getting many emails is good, because I'm important, heh :D 06:34
samcv usually a mix of script based questions and sometimes technical questions and such
though there is some thread in the huge like tree shape the unicode emoji 5.0 characters now being final thing 06:35
about stability of country codes and such which idk. i guess maybe sounds boring but it's at least important. not arguing about what 'recommends' means. and then peolpe finally settle on that recommendhs means... drumroll. "recommends" 06:36
which i could have told you but. whatever
06:37 RabidGravy joined
Voldenet heh, I'd advise against using such fuzzy terms, I'd use "suggests" instead ;-) 06:37
samcv that's different though 06:38
i mean recommends means that it is recommended but not required
Voldenet and suggest means it's a good practice but not required
pretty much
samcv and is not needed to be Unicode compliant and other systems should not assume conformance with said recommendation
but they use recommended in many documents. which is loose and not really a strong technical thing 06:39
06:39 wamba joined
samcv well. it's recommended. idk how else to say it. lol 06:39
and people arguing about flags 06:40
Voldenet actually, RFC is pretty clear on what "RECOMMENDED" means
samcv angry because england and wales got flags because of sports
This word, or the adjective "RECOMMENDED", mean that there 06:41
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
yeah. exactly
Voldenet meaning "implement it unless you're working on 10kb ram"
samcv and people not understanding how unicode chooses things 06:42
"i am mad because these symbols are used more in practice than mine, and they were included. becuase i don't care about sports"
"but i care about XYZ"
Voldenet unicode could just set up a code for inline bitmaps just for them :-) 06:45
that'd be a great april fools joke
samcv well that is their recommendation
in the technical reports even now. for a long time
to implement images 06:46
Voldenet uhh, hmm I can imagine hardware being fast enough for this, but it adds a layer of complexity nobody really needs
samcv also there is no reason why a vender can't allow use of a flog not on their list. if it follows unicode's rules
for how they should be laid out
that is the best way for it to be officially included in the next revision 06:47
dlike it says california is not a standard sequence, but gives an example of how that would be laid out, and for some other non country things 06:48
Voldenet hmm, there are also political things at play, some people would see Basque or ISIS with separate flags for instance 06:49
samcv lol
TEttinger hehe unicode emoji is a silly thing to argue about because it's a silly thing in general
samcv depending on what it is yeah
Voldenet TEttinger: well, I can't imagine any font fully implementing unicode
some fonts try, but I doubt they're complete 06:50
samcv just becuase it's not on the list doesn't mean unicode hasn' already defined how to properly construct it
but it's touchy for some people
samcv they basically just made it have certain 'standard' onnes to support emoji 5 or whatever, which was some more popular flags. which will get people to integrate support for those encodings of those flags
which will then... make it easier to add flags for less popular things
TEttinger and then with joiners...
samcv so they should not be unhappy
Voldenet TEttinger: actually U+1D00D is "Byzantine Musical Symbol Apeso Ekfonitikon" 06:52
TEttinger you could have genderbent muhammad emoji, not controversial at all
Voldenet I don't know how it actually looks like, because none of my fonts support it
samcv Indeed, why isn't the flag of Texas there already so as to terminate
the abuse of <U+1F1E8, U+1F1F1>. Technically, at least, it has the
justification of being a formerly independent country, though I don't
know that they have any national teams.
Is anyone working on the issue of flags for the whole of Ireland?
Different sports have their own 'national' flags.
ok gotta stop reading this particular thread
TEttinger haha
samcv they showed an example for how one would construct a california flag. and then next to it said it was not official but conformant with construction. idk 06:53
people don't understand that i guess. that they basically handed them the way to make texas
06:53 Cabanossi left
TEttinger I mean... what we need is some kind of turing-complete way to describe Unicode encodings 06:53
samcv don't we already
TEttinger procedural unicode version generator
samcv also define describe
Voldenet TEttinger: 0xBITMAP
TEttinger hehe
samcv what do you mean by describe 06:54
TEttinger declarative language that can define an arbitrary sub/superset of unicode graphemes and use it in some cross-compatible way
including, for example, defining a texas flag as they do
but assigning it to its own codepoint in the subset 06:55
06:55 Cabanossi joined
Voldenet I think only regular letters (or symbols, in any language) should be a part of the official UTF standard, bitmap should work for the rest 06:55
TEttinger yes.
dingbats and emoji are really sketchy
Voldenet fonts can't think of other ways to display flags, so it's just a bit silly to include them
TEttinger but it kinda needs better vector support than a bitmap, since most fonts aren't bitmap fonts 06:56
Voldenet Okay, some emoticons can be included, but ehm... flags?
I can imagine having "asian people" font for emotes or "monkeys"
TEttinger since those originated on japanese phones?
but everyone uses them
Voldenet I try not to, it makes me look silly. 06:57
TEttinger every cultural group has people who use them
u-ou how do you reference a method like &foo for sub foo?
TEttinger (not the Amish, though)
Voldenet u-ou: you mean as an argument? 06:58
m: sub x(&my-sub) { my-sub() }; x({ say "I work!" }) 06:59
camelia I work!
u-ou you can reference the subroutine 'foo' without calling it like &foo. but how do you do that with a method?
Voldenet ah
u-ou actually. maybe I don't need to. but I'm interested now. 07:00
I might just use an anonymous function
samcv well. people use emoji and flags to communicate. and that's unicode's job. to enable the interoperability of the display of graphics with semantical meaning
TEttinger but each carrier displays them differently 07:01
and each font!
samcv they are used by people to communicate. so therefore they are important. same with many different scripts, and they added dingbats to allow conversion between encodings which already were encoded that way
that is not unicode's fault 07:02
like apple changing pistol to a ray gun. that's not what it is. it's the symbol for a pistol
you can't just change what the meaning of the codepoint is because reasons 07:03
that goes against the whole spirit of unicode and interoperability

samcv well it has to be a pistol
not something that is a fictional toy weapon
u-ou well, that's probably all I need
Voldenet u-ou: actually, just {$a.m()} would suffice
samcv also. they should maintain consistent color
u-ou yeah 07:11
I wonder if you can ref. methods though
Voldenet samcv: too late, on my system it's silver pistol, but on reference graphic it's black 07:13
u-ou oh well. I'll just use an anon. func. 07:14
RabidGravy boom! 07:15

Voldenet Hm, am I doing something wrong? 10:07
lizmat Voldenet: Perl 6 doesn't have predictable destruction 10:13
if you want to make sure something gets destroyed when leaving a block, you will have to do it yourself
m: class x { submethod BUILD { say "i live" }; submethod DESTROY { say "i die" }}; { my $x =; LEAVE $x.DESTROY }; 10:14
camelia i live
i die
Voldenet hmm, that's quite golang-ish
does perl have some cool feature for that, like C++? 10:15
lizmat in a bigger program, .DESTROY *will* be called as soon as $x is kicked in a GC run
but if you have a small program, rakudo perl 6 just lets the OS take care of cleanup
Voldenet m: use nqp; class x { submethod BUILD { say "i live" }; submethod DESTROY { say "i die" }}; { my $x =; undefine $x; }; nqp::force_gc()

Voldenet ah, wonders of GC 10:16
10:16 Peter_R left
lizmat actually, a GC run will mark the object first 10:16
a subsequent run will actually call the .DESTROY 10:17
Voldenet oh, moar's GC doesn't do generations?
lizmat Voldenet: moar uses a nursery approach
Voldenet hm
nothing too wrong with that I suppose 10:18
lizmat # the theory implemented in Moar
10:18 Peter_R joined
Voldenet hm, sorry, I don't have that book 10:20
but it's mark and sweep, right?
lizmat that's the idea, afaik 10:21
and a nursery for short-lived objects # Garbage collection section
Voldenet well, but I can be sure that DESTROY works, that's the most important 10:22
I would admire having some solid method that'd force a "full gc run that destroys inaccessible objects"
lizmat indeed... if you want predictable destruction, you will have to take care of it yourself
Voldenet to ensure my destructors are working fine
lizmat I think doing the force_gc twice, is fairly sure way of testing that 10:23
especially in single threaded programs :-)
Voldenet hm, C# has the using and IDisposable block for that, perl could use something similar
lizmat but, what do you want to test? 10:25
that the .DESTROY method is called, or that it does the right thing?
if you want to test it's doing the right thing, why not just call it ?
Voldenet some simple stuff like calling closing some connections
heh, fair point :) 10:26
still, perl has much syntax, one "new and destroy on leave" wouldn't hurt
lizmat well 10:27
one syntax is:
my $handle will leave .close = open("file")
my $handle will leave { .close } = open("file") 10:28
which will create a LEAVE block for you
Voldenet That's actually pretty nice, but don't we have any nice role for that? Explicitly calling destructor feels very Cish ;P 10:29
I might be a bit intoxicated by C# here though, I like how they solved it.
lizmat well, it's one of the consequences of not doing reference counting
so how did C# solve it ?
(reference counting in a threaded world is a recipe for either slowness or disaster) 10:30
Voldenet they have normal classes with constructor and destructor
and additionally
IDisposable interface having method { void Dispose(); }
and when a class implements IDisposable, it can be used in such way
using(var sth = new MyClass()){ sth.Test(); } 10:31
and Dispose is called automatically upon exiting the "using" clause
and real Destructor is usually just keeping eye on IDisposable (hand-written "if it wasn't disposed then dispose") 10:32
lizmat hmmm... feels like we should be able to do something like that
10:35 domidumont joined
lizmat m: sub using(\a) { class { method AT-KEY(\b) { a.DESTROY; b } }.new }; class A { method DESTROY() { say "died" } }; using({ say "foo" } 10:36
camelia foo
lizmat not sure I like the syntax though 10:37

Voldenet lizmat: whoa, that's quite nice 10:41
but it doesn't preserve all the features - how do you actually use this object created? ;) 10:44

Voldenet ah 10:44
hm, okay, I figured it out and it's very similar to what C# does 10:46
10:46 notbenh joined, domidumont left
lizmat m: sub using(\a) { class { method AT-KEY(\b) { a.DESTROY; b } }.new }; class A { method DESTROY() { say "died" } }; using(my $a ={ say $a } 10:46
lizmat so yes, basically the same way that C# does it 10:47
Voldenet C# can also do this: > using(my $a = using(my $b = using(my $c = { say $a, $b, $c; }
But well, the syntax doesn't fit perl anyway. 10:49
> my $handle will leave .DESTROY =; 10:51
lizmat you still need a block there for now
my $handle will leave { .DESTROY } =
but yeah
