RabidGravy 120 unique module authors now, however 10 authors are responsible for more than a third of the modules 00:35
oh well
anyway toodles, getting a bit late here 00:36
leont I think that sort of distribution is normal 00:37
"10 authors are responsible for more than a third of the modules" means they have 4-5 modules each on average, that isn't that much 00:38

Herby_ I'm still having a hard time wrapping my head around OO 04:50
classes/objects etc
skids It just shadows the .Str method from Int, which is what is used internally by say and friends. 04:51
It's not really useable though, because it can't do math without losing its type. 04:52

frankjh Hi, I have an initial version of my first perl6 library ready. It does public key en/decryption using nacl. Please see github.com/soundart/perl6-tweetnacl . Known problems: I can use it with Configure.pl, but panda does not work. Very uncertain wrt to my perl6 usage... 08:41
moritz frankjh: I'm not very familiar with that part of Perl 6, but I'd suggest looking at other projects that have C components 08:42
frankjh: Inline::Perl5 in particular is known to currently work; it has a configure.pl6 an Build.pm
08:43 linkq joined
FROGGS frankjh: one thing I spot: here[^1] you state you expose it as TweetNacl, but in the META6.json you expose it as "Add"... [^1] github.com/soundart/perl6-tweetnac...-load.t#L5 08:43
frankjh moritz: Thanks. Is there a way to do a panda install locally? 08:44
nine panda install .

nine .tell hoelzro \o/ thanks a lot!
yoleaux nine: I'll pass your message to hoelzro.
frankjh FROGGS: Thanks. I started from a perl6 example using an 'Add' module on github. 08:46
moritz FROGGS: star rc0 also works for me with a custom prefix
frankjh wrt.: META6.json, is the libtweetnacl.dylib name ok, or is this OS dependant? 08:47
I am building tweetnacl.so 08:49
FROGGS moritz: ohh cool, I'd not tested that
frankjh: a .dylib is for OS X only
moritz FROGGS: so you have my axe, and my green light :-)
FROGGS *g* 08:50
FROGGS needs to watch that again
08:50 schnuppi left
nine frankjh: when you use "tweetnacl" as name in your META.info and in your is native traits, rakudo will expand that to tweetnacl.dylib on OS X, tweetnacl.dll on Windows and libtweetnacl.so on Linux 08:51
FROGGS frankjh: yes, that resources entry in the meta file is problematic
frankjh FROGGS, nine: So I simply remove the .dylib extension?

frankjh: I fear you wont get the lib installed whatever you do 08:53

obviously I guess
nine FROGGS: either that or people just imagine using Inline::Perl5 :)

moritz Inline::Perl5 doesn't really allow you to call Perl 5 code; it just has huge number of popular p5 modules baked in, so nobody noticed
(p6 ports of the p5 modules, I mean :-)
nine moritz: ssssht!
frankjh Ok. I will try to use the build setup style from Inline-Perl5. Thanks! 08:55
nine The Build.pm and configure.pl6 are still a bit more complicated than I'd like. One of these days I'll propose a patch to LibraryMake to simplify them. 08:56
FROGGS nine: and we should work on supporting longnames in meta files 08:57
nine We should work on supporting longnames everywhere...
FROGGS we... dont support them anywhere? 08:58

CurtisOvidPoe Hi all. If I define a class as a subclass of a numeric type, but I wanted to remove some numeric operators, how would I do that?
FROGGS CurtisOvidPoe: I guess you cant... 09:26
CurtisOvidPoe: do you have an example, where I could see *why* you want to remove ops? 09:27
nine frankjh: the sub native in Inline::Perl5 is almost obsolete now. I could just as well write my constant $p5helper = %?RESOURCES<libraries/p5helper>.Str; sub p5_init_perl() is native($p5helper) returns Perl5Interpreter { ... };
CurtisOvidPoe FROGGS: masak was telling me that I can, but I forgot to follow up with him on how to do that. Maybe I misunderstood him?
nine frankjh: it used to contain much more code before we got support for %?RESOURCES 09:28
FROGGS CurtisOvidPoe: you can of course add these ops for your type, and because these will be more specific they will be picked
CurtisOvidPoe: but infix:<+>(Int, Int) will always be a valid candidate otherwise, when you subclass Int 09:29
CurtisOvidPoe FROGGS: Let’s say I declare “class Temperature::Fahrenheit is Num { … }” There’s no point in *multiplying* temperatures, but adding them (to take average temperatures) would make sense, but only if I was adding them to other instances of Fahrenheit classes.

masak it's trying to numify $t1 for some reason 10:11
adding a `method Numeric { self }` to Fahrenheit causes an infinite loop 10:12
surely doing a custom infix:<+> on one's own objects doesn't *require* the objects to be Numeric?
RabidGravy is there a (Numeric() , Mu ) candidate for <+> ? 10:13
arnsholt No, that'd be weird...
DrForr Wouldn't that be method Numeric { self.temperature }?
masak DrForr: no, that'd defeat the purpose
DrForr: we want the temperatures to act as number-ish objects
adding `does Numeric` to the class also causes an infinite loop
all I can say is that this doesn't behave as I remember it :( 10:14
RabidGravy ah, it's a typo
DrForr I understand the purpose, I'd just thought that returning the internal object as the typed object would be TRT.
RabidGravy $t1 + $2 vs $t1 + $t2
with the latter it works 10:15
masak ahhh
CurtisOvidPoe DAMN IT! :)

huf that's quite an obscure error message for a typo :)

Skarsnik RabidGravy, hm, did you already work with struct like s { char *data; int length}; and using Buf work for the char *data? 13:20
llfourn I personally would be happy if dynamics become isolated inside start {} if that led to greater optimization opportunities.
13:21 virtualsue joined
timotimo we don't guarantee safety of lexical or dynamic containers IIRC 13:21
RabidGravy Skarsnik, strange you might ask that :) GDBM uses a struct just like that to pass the keys and values, it segfaults :-\ 13:22
timotimo all we can do for that at the moment is use CArray ...
llfourn I would have thought lexical like start { my $a = '' } would be guaranteed but I know nothing
arnsholt CArray should work for that use case 13:23
timotimo if the lexical is *inside* the start, sure, that's no problem
arnsholt Although you have to be very careful not to exceed the array bounds, of course
llfourn timotimo: ok then we are on the same page ;)
timotimo shared lexicals, on the other hand ... 13:24
RabidGravy yeah, Str no good in that place
nine What exactly does nqp's =:= compare? It's not nqp::objectid, isn't it?
timotimo no, objectid causes an object to get a fixed ID in the future
it's equivalent to a pointer compare 13:25
nine So what does it mean when two objects have the same nqp::objectid?
timotimo it's the eqaddr op 13:26
that's the same as eqaddr, but with a side-effect on the objects you get an objectid of
nine So if they have the same nqp::objectid, =:= should give 1?
timotimo hmm 13:27
i think so

nine Before we can do a new release, we _have_ to decide how to handle language versions. Schedules are much less important than that.
[Coke] We probably should have said "and we're taking january off", but I didn't think of that in time.
Skarsnik hm, how I am supposed to transform a 40 in is string value (not '40')?
[Coke] nine: agreed, if it comes to that, we skip january anyway.
FROGGS nine: true
leont I have a «return unless … for» construct that seems to have been broken since february, but I don't understand why

leont Is there a pretty way to classify into two groups? List.classify seems more suitable to bigger sets of classes 14:10
I could do some sort of Swartzian transform I suppose, but it'd be ugly
theorb Hmm. What's the status of perl6 on jvm -- is it believed to be working? Has anybody tried android? Is there (reasonably fast) perl6-java interop using that route? 14:11
leont e.g. ($files, $dirs) = @entries.classify-bool(*.d)
AFAIK p6 on jvm isn't fully operational, though it isn't fully broken either
RabidGravy theorb, I believe the answer right now is no
Zoffix Heh twitter.com/marcusramberg/status/6...9800509444 14:12
[Coke] last I checked, rakudo-j wouldn't install.
Zoffix The next time someone points out the "anti-Perl-5 attitude" in this channel, I'll point to that tweet by the core Mojolicious developer :)

Zoffix theorb, the skippage of tests by Rakudo is one, what's the other one? 14:14
nine FROGGS: I shouldn't have to recompile rakudo after doing make install in MoarVM, should I? 14:15
[Coke] The tag was not moved.
theorb leont, RabidGravy: Hm, that's rather a shame. Writing android apps in perl is something I've long wanted to be able to do, and perl6 is probably perl enough. I tried, and failed, to get perl5 cleanly calling into jvm code. 14:16
lizmat cycling&
theorb [Coke]: That's not the impression I get from that twitter thread. Rather, the tag did move, but not in ways that are really bad.
RabidGravy I'm sure it's fixable, just no-one has pitched in
[Coke] theorb: as the release manager - I did not move the tag. 14:17
Zoffix I think Marcus is making the assumption that the tag was moved just because they were told to get newer Rakudo to fix a panda problem
[Coke] I am literally the best person in the world to answer that question.
nine Zoffix: yes, definitely. 14:18
RabidGravy first the logo, now a tag, it's almost like people are desperate to find a problem
Zoffix :D
llfourn RabidGravy++ agreed
14:20 FritzZaucker left, frankjh left
llfourn They are disappointed that p6 is not stable and ready-for-production like p5. Though to me p6's ready-for-production means ready to produce fun. And in that way it is. 14:21
but I don't think many ppl outside this channel think like that :P
RabidGravy people don't have long enough memories 14:22
theorb The problem is that "perl6 has been/will be released" seems to mean different things inside and outside the community, and it appears that the perl6 spec 6.c was frozen, but not an implementation of that spec.
Zoffix It's stable-enough for my purposes.
theorb ...and the spec isn't what people have been waiting for.
llfourn RabidGravy: go on :) 14:23

mspo is panda supposed to work? :) 14:38
nine mspo: absolutely
_sri Zoffix: you're also implying perl6 was usable already, but there is no way anyone would bet their company on it yet
Skarsnik RabidGravy, what kind of error you get?
llfourn nine: don't be too sorry the point is -Ofun after all :)
jnap is there an example of a 'canonical' P6 module I can cargo cult? I was thinking of trying to port something reasonably simple but hard enough I'd learn something, probably DOM::Tiny but I wasn't sure the right way to start
[Coke] _sri: No one is suggesting that someone bet their company on it.
_sri i think TimToady even called it production ready
[Coke] ok. If you don't think so, why are you here? 14:39
Zoffix _sri, then clearly there are vast differences between what "usable" means to people.
[Coke] Seems like it would be a burden to have to listen to us talk about how much we like it.
llfourn _sri: it is if you are trying to produce fun :)
nine _sri: surely there is a spectrum between "unusable" and "bet your company on it"?
Skarsnik jnap, not sure to understand what you call a canonical module x) 14:40
Zoffix _sri, the release notes specified what it means to us. It's unreasonable to make fun of the release efforts and ignoring the release notes.
Quom__ jnap: A while ago, JSON::Tiny served a bit of a role as that :)
jnap FWIW I'm trying to put myself in a good mood and think Perl6 is production ready in the way that Moose was production ready when it was version 0.3 :)
Zoffix jnap, I'm quite proud of github.com/zoffixznet/perl6-Test-Output
[Coke] My concern about the that small tweet stream I saw are twofold: people are having trouble getting perl6 to work. Ok. we are working on that; tickets noting the problem would absolutely help; and correcting some misinformation that got out there.
Skarsnik Zoffix, damn you should do a warn-ok or something! 14:41
jnap Zoffix: like with Perl5 we have EUMM right as the basis for describing dependencies and meta data
Zoffix jnap, (ignore the _chromatin dir). Also jnap++ we really really REALLY need a DOM::Tiny port in P6. I've actually started a port of Mojo::DOM, but got stuck at porting regexes. Feel free to steal stuff (I think I ended after porting tests only and I'm unsure if they work): github.com/zoffixznet/perl6-DOM-Parser
_sri [Coke]: "if you don't think so"?
jnap I see a few things around with meta.info, should I cargo cult that?
Zoffix jnap, yeah 14:42
jnap, there's Test::META that can tell you if you screwed up with the META file and its docs also reference the spec portion describing that file.
huggable, module Test::META
Skarsnik Should be add on the front page of perl6.org that the Christmas release has issue with panda and stuff?
huggable Zoffix, Link to module: modules.perl6.org/repo/Test::META
jnap cool thanks! do we think regex are still the way to go, or should I not be using the cool new grammar stuff?
Zoffix Skarsnik, does it still?
mspo gist.github.com/msporleder/4e9fa7c1429f2ca9362f any help? 14:43
[Coke] _sri: sorry, yah, there's no antecedent there; "think its worth using" I guess is the closest thing to what I was thinking.
jnap Zoffix: I'll fork that and see what I can do.
FROGGS nine: did you disable JIT?
RabidGravy Skarsnik, I'm struggling to find a way to construct a suitable CArray
FROGGS nine: did you disable or spesh or so?
Zoffix jnap, my (possibly ignorant) suggestion is to go with a regex, because grammars are slow.
nine _sri: re-watching Larry's talk right now. He didn't even promise anything. He said "we're not exactly promising it. We're more like projecting and planning for it".
FROGGS nine: err, "or spesh or so?"
nine FROGGS: nine@sphinx:~/rakudo/nqp ((460c042...))> MVM_SPESH_DISABLE=1 MVM_JIT_DISABLE=1 perl6 -e 'use nqp; say nqp::eqaddr(0, 1)' 14:44
RabidGravy Zoffix, Skarsnik if you look in the recent Test::Meta it actually does a test for a warning generated from the parsing of the META file
nine 0
_sri [Coke]: think i've been here from the start, and in #parrot...
FROGGS nine: lemme check
Zoffix jnap, I think modules.perl6.org/dist/HTML::Parser::XML uses grammars. It's unberably slow last time I tried it. Maybe see what it's doing too, for learning
Skarsnik No it does not
jnap ok, so grammars maybe too slow right now?
14:45 frankjh joined
Skarsnik and I think writing a full html5 parser in perl6 is too much (useless) work 14:45
Zoffix Skarsnik, why?
llfourn Skarsnik: isn't there a few of those already?
Zoffix Skarsnik, we're also talking about a port, not from scratch
Skarsnik Because it's too big?
Zoffix Nah 14:46
_sri [Coke]: i've voiced critical opinions for at least 10 years, and not once someone asked me to leave, wonder what changed
Zoffix Skarsnik, what do you mean "should do a a warn-ok"? I don't think Test::Output is the right place for such a subroutine
Skarsnik Zoffix, RabidGravy it should be in Test I think x)
RabidGravy feel free to adapt the code :) 14:47
FROGGS nine: I like get a gazillion lines of output when running your one liner
Skarsnik and for html5. the spec is rather big and It's reinventing the wheel to write another one instead of using something properly/fully tested
leont isn't so sure Test should grow too much 14:48
FROGGS nine: and that's the line I added: fprintf(stderr, "eqaddr %p == %p\n", GET_REG(cur_op, 2).o, GET_REG(cur_op, 4).o);
leont I'd rather go into the direction of an extensible testing framework
_sri [Coke]: but maybe you're right, i don't belong here anymore
nine _sri: he actually elaborated quite a bit on that point. Followed by an explanation about what will actually be released. Which is "the test suite". Followed by "nobody in their right mind expects a .0 release to be perfect".
Zoffix Skarsnik, do you mean using a C lib?
Skarsnik, I don't think that's very user-friendly
Skarsnik hu, why? 14:49
Zoffix Skarsnik, I don't want to install stuff with my package manager just to use a Perl 6 module. I might not even *have access to* a package manager to install C libs
Also: Windows
mspo wouldn't panda/zef compile the c lib for you?
Skarsnik how about DBIish/sqlite?
mspo also C works on windows :)
14:50 donaldh joined
Zoffix Skarsnik, we had the same conversation on the Issue on DBIish about bundling sqlite lib, remember? :) 14:50
mspo but ::PP is always my preference
Zoffix mspo, Windows doesn't come with a C compiler.
FROGGS nine: how do I reproduce that global_merging explosion?
Skarsnik You can always provide a dll if the lib is standalone for windows
Zoffix mspo, and authors aren't bundling the C lib
FROGGS Zoffix: you can ship prebuild dlls
Zoffix FROGGS, that's good. 14:51
FROGGS Zoffix: I did that with Alien::SDL and others (P5)
nine FROGGS: rt.perl.org/Ticket/Display.html?id=127107 has a simple test case
FROGGS these alian dists let you choose to use system libs, build the libs from source, and use prebuild libs
Skarsnik Zoffix, my issue with dbiish/sqlite is like FROGGS say, I prefer to offer a choice that just 'provide the lib' 14:53
mspo Zoffix: so I need to install the linenoise lib before trying to panda install it?
Zoffix mspo, ??
nine FROGGS: wow, my moar binary is from Dec 28th. There's something very wrong with my installation 14:54
FROGGS that would explain one thing :o)
nine: I can reproduce btw
Zoffix Skarsnik, I was not given that choice when I tried to use the SQLite back end. I was told the lib was not installed and I had to invoke my package manager. In an alternate universe I went without DBIish because I did not have root perms on my box.
RabidGravy mspo, it is at option for the module author to bundle and compile the library, this doesn't really work for some stuff
mspo Zoffix: as in github.com/antirez/linenoise.git first 14:55
FROGGS nine: and there is a copy&paste in the module loader code
hoelzro mspo: you don't need to
yoleaux 08:44Z <nine> hoelzro: \o/ thanks a lot!
[Coke] For the logs, anyway, I wasn't asking _sri to leave. I was trying to ask what he got out of it.
FROGGS nine: look at line 146
hoelzro linenoise.c is bundled with Linenoise
mspo k
Zoffix mspo, I think you're confusing me with something. I've no idea what you mean :)
s/something/someone/;
[Coke] .tell _sri not sure if you'll get this, but I wasn't asking you to leave; I was trying to ask what you got out of the experience.
yoleaux [Coke]: I'll pass your message to _sri.
Skarsnik Zoffix, actually you can install the lib yourself and set a ENV variable
Zoffix [Coke], that's how I saw it too
RabidGravy something works too, "pardon me ma'am I mistook you for a join't stool" 14:56
Zoffix Skarsnik, what do you mean by "install the lib yourself"?
Skarsnik, I'm a Perl 6 user not a C library installer.
Skarsnik but since META.info is actually blind to external dep, it can't tell you
Zoffix :(
RabidGravy Zoffix, I proposed an Alien thing to assist in this and all sorts of freaking out ensued so I forgot the idea 14:57
llfourn [Coke]: tbh it did sounds like if you are offering criticism you have no reason to be here
Skarsnik Zoffix, well if you have compiler right, you can compile sqlite yourself and tell DBIish:sqlite where to find it
nine FROGGS: you mean the source/target thing? Already noticed, but it's unrelated to this issue
llfourn *it did sound like you were saying
FROGGS nine: k
Zoffix Skarsnik, I don't have a compiler on one of the web hosts I use. I don't have a compiler on my Windows box.
Skarsnik, and I don't KNOW how to compile things :)
FROGGS nine: you can leave that bug to me if you want 14:58
nine FROGGS: do you already have an idea? 14:59
Zoffix And it's not just about me. I also want to distribute my application. And I don't want to write lengthy installation instructions for my $paying-client to get confused about.
theorb OK, I'm having black-sheet issues. Is there a nice "here's how to go from zero to starting on writing a grammar for something" tutorial -- IE basic framework code that reads in a file, applies a grammar, and dumps the results.
FROGGS nine: not yet
Skarsnik Zoffix, you hit an another issue: having to provide prebuilded library for some plateform :)
FROGGS nine: but I know that code path quite well
nine Then you have a clear advantage there :) 15:00
llfourn theorb: I haven't seen a good tutorial unfortunetly. but check out: rosettacode.org/wiki/Read_a_configu...ile#Perl_6 15:01
hopefully that' sone of the examples that still works!
RabidGravy also the grammars page in the docs has a reasonable csv example
llfourn theorb: ^ that's probably better 15:02
it shows you "actions"
Skarsnik Zoffix, I am curious, did you try to build the stuff Mojo::UserAgent does with H:P:X?
RabidGravy, damn I can't speed up xml parsing on gptrixie using gumbo for xml because of the same struct than you x) 15:04
Zoffix Skarsnik, ? Mojo::UserAgent is an HTTP/WebSocket client, H:P:X is... the parser, I'm assuming?

Zoffix jnap, not all :) It just tokenizes HTML with regexes :P 15:13
RabidGravy is there any example of creating a CStruct with a CArray attribute that is populated to pass to a native sub? I'm really struggling to find an incantation that works
15:13 Cabanossi left
Skarsnik RabidGravy, nothing in NC test? 15:14
jnap ideally once we had a working DOM::Tiny port we could see about finding Perl6isms like returning promises instead of blocking, etc. but that is like far away for me right now
Zoffix jnap, I wouldn't bother with that. If I'm parsing something huge and want non-block, I'll create my own promise. 15:15
[Coke] llfourn: ya, in retrospect, I can see that. Wish I had not been AFK to deal with that before it escalated. my fault.
Zoffix jnap, and if it's something small, I don't want to spin up a thread just for it and do any sort of promise handling. I just want the result 15:16

Unless there's some way to temporarily make $PROCESS::OUT save output into my variable, same as I can with $*OUT
geekosaur if you compile with optimization, both code and variables can be removed; variables can end up in registers and information about what register doesn't make it into the debug information because it isn't static 16:12
AlexDaniel I'm not sure if they will hire people for Perl 6 work any time soon, but I'm pretty sure that a lot of people will start using Perl 6 at work for some of the tasks
CurtisOvidPoe AlexDaniel: Agreed. Most new languages, if they take off, still take 2 to 3 years before they start getting traction.

pyrimidine I had someone post a bug that seems related to precomp, any ideas? Works locally for me github.com/cjfields/bioperl6/issues/8 16:13
geekosaur (that is, the compiler may choose to switch registers if it's convenient because some machine operation leaves its result in a different register and there's no code elsewhere in the function that needs it to be in the first register)

moritz $_ is only passed on through blocks that don't have explicit signatures
Zoffix Ah
moritz not through routines
the defaull signature for blocks is $_ = $OUTER::_ 16:44
and for subs it's *@_ iirc
zwu Ah, I see, $_ is the for the block parameters, will there be multiple parameters passed to block? and How to do that?
dalek kudo/nom: 2d91f08 | (Stefan Seifert)++ | src/Perl6/ModuleLoader.nqp:
Fix rare "duplicate definition of symbol" errors

When an EXPORT or EXPORTHOW routine assigns a symbol as in: EXPORTHOW::<grammar> = TracedGrammarHOW; instead of binding it, the test in Perl6::ModuleLoader::merge_symbols for equivalence of source and destination symbols fails because it compares the containers of those symbols instead of the symbols themselves.
Fix by always decont'ing before comparison.
Many, many thanks to FROGGS++ for finding the final piece of this puzzle!

rindolf azawawi: someone was on ##programming asking about how to program C++ for Arduino with no prior programming experience.
RabidGravy azawawi, so you'll be making a serial module then :)
azawawi Zoffix: alright :)
rindolf azawawi: I told him he should start with something easier and he didn't listen.
azawawi rindolf: true 16:55
rindolf azawawi: they hardly ever do.
azawawi rindolf: rpi is easier with the python route i took 2 years ago :)
RabidGravy to be honest the arduino c++ shields you from the gory details 16:56
rindolf azawawi: OK.
azawawi rindolf: but with all the resources on arduino, docs and examples, someone can cook up something pretty fast given some programming experience 16:57
alpha123 arduino c++ probably isnt the worst possible programming environment actually
lots of docs, you can make cool stuff, etc 16:58
azawawi i read that the difficult thing about is the debugging part
alpha123 granted c++ will probably scar him for life
azawawi but that holds for every device out there if you think of it
alpha123 rpi debugging isnt that bad 16:59
pnu is it possible to make .rakudobrew "relocatable" in the filesystem? Eg. in my .rakudobrew/moar-nom/install/bin/perl6 script all paths are absolute, which makes it not relocatable.

AlexDaniel arduino + perl 6? Huh? 17:09
Skarsnik Look like arduino + C + perl6 probably x) 17:10
alpha123 given the current state of perl6 compilers, embedded programming seems rather optimistic 17:11

Zoffix ah
saaki, none that I know of
saaki, `perlbrew` says "lib Manage local::lib directories.", which isn't very descriptive, but you can do `perlbrew lib` to get more info 17:33
saaki closest i've come up with is to have multiple .rakudobrew directories
Zoffix: oh ok, i did "perlbrew help lib" and didn't see that :) 17:34
Zoffix Seems like my only solution is to set $PROCESS::OUT/ERR to my custom IO::Handles with a Bool $.is-capturing attribute that will control whether they're capturing or whether they should just proxy the data to *real* $PROCESS::OUT/ERR. -_- 17:35

hoelzro should POD after =finish be parsed?
I put some POD after =finish (a la POD after __END__ in P5), and perl6 --doc doesn't render it
hankache hi hoelzro
mspo wow erlang might actually add unix socket support soon 19:08
hankache hoelzro is it by design or the render is bogus? 19:09
hoelzro hankache: that's what I'm wondering 19:10

timotimo AFAIK my nexus 5 doesn't do LTE
perigrin and when it hits edge I get a paperback book.
timotimo and i don't have a data plan that lets me have LTE. also, in germany, LTE data plans are ridiculously bad.
geekosaur my n5 did lte fine

the EU has come up with some kind of general maximum cost for roaming 19:58
that's a good step forward, but it's still a ridiculously low amount of data you can get for a ridiculously high price

.oO( hm, perhaps consider submitting a request to IAmA on reddit )
todd_ Guess I'm spoiled by cpan, but I'm disappointed by my inability to get any packages built via panda. I want to start working with P6, and will keep trying, but others this position will probably rage quit.
diakopter I don't understand the purpose of your absurd rhetorical question
timotimo: were we talking only about "in people's homes where they won't let you use their wifi?" 20:08
RabidGravy to be honest, the Wifi here is so bad I use a cable most of the time 20:09
timotimo okay, so the Fi thing is supposed to be a mobile data plan that has a bit of cheap extra worldwide data for you, too? 20:10
TimToady todd_: well, rage quitters would probably not be our first choice of new recruits to the community in any case... :)
perigrin RabidGravy: I would but there is no port on my iPad for it. 20:11
diakopter timotimo: Google Fi is only for USAians. so, when globally traveling, there will be WiFi generally most public places of transit, as well as essentially every hotel and airbnb
timotimo diakopter: saying "fi figures you'll use mostly wifi" sounds a bit like "yeah, we sell you a data plan, but you don't actually get any data. you wouldn't use it anyway, right?"
AlexDaniel TimToady: what's that? An exam for refugees?
TimToady I've never been keen to be co-dependent for people who play the "I'm taking my marbles and going home" game 20:12
timotimo anyway, gotta go! :(
diakopter well it's for being able to make voice calls in emergency and SMS, and a tiny bit of data where there's no WiFi
20:12 darutoko left
timotimo TimToady: i do prefer "ragequit" over "ragestay", tbh 20:12
perigrin can't even find his marbles anymore.
diakopter I think I never had any..
todd_: what's your current obstacle 20:13
or is it Useragent module specific?
RabidGravy perigrin, strangely my tablet and the tv are fine with the wifi, my laptop and phone not so much
todd_ tests failed in Useragent, and LWP::Simple fails to build in Task::Star
diakopter if it's specific to just that module, seems unfair to blame all of "getting a module built by panda" 20:14
perigrin RabidGravy: the last time my router died ( couple months ago actually) I replaced it with a mikrotik and I've been incredibly happy since.
diakopter "I can't publish a module because someone put some crap in the module index"
mst diakopter: (1) the user is always frustrated 20:15
todd_ BTW, not threatening to take my marbles home, just the a lot of people will not bother to come and ask questions here, and there isn't a lot of help on building these things in the usual places yet.
mst diakopter: (2) the installer is the thing directly in front of the user therefore the thing they're most likely to be frustated -at-
todd_ yes, and at the end of the day, I just want to get a tool chain working so I can start developing in P6 20:16
TimToady Both the "take my marbles" ploy and the "fait accompli" ploy tend to be used by people who are not willing to work inside a community where compromises are valued over ultimatums.
20:16 marmay left
mst todd_: 'panda install HTTP::UserAgent' just completed fine here 20:16
diakopter it would be nice to have docs for making panda work, and also travis-ci in a github repo, for that matter
RabidGravy todd_, the problem with H::UA there is that it goes to the network for some tests, you could either run with --notests *or* try and set $HTTP_PROXY in the environment
todd_ I have no ploys, just asking for help. Willing to do the work.
mst NETWORK_TESTING needs to be set for it to care about that, I think 20:17
certainly I got a skip based on it not being set
TimToady todd_: wasn't accusing you of that :)
RabidGravy mst, not necessarily *all*
TimToady was just using your remark to launch my own diatribe :)
todd_ is $HTTP_PROXY set from the shell's http_proxy var
mst ah. so the 'check NETWORK_TESTING' block might want to be copied to other places?
TimToady todd_: do you know about #perl6-toolchain? 20:18
mst TimToady: the trouble with ultimatums is they're only fun once
RabidGravy mst, yes, it has only been applied to places that are always trublesome :)
todd_, let me look at the code again :) 20:19
mst if this is a bug in a specific module's tests, I dunno if that's exactly a toolchain thing as such
TimToady lunch &
mst (though given that channel's relativelty quiet I don't really mind, we can always split stuff out again later if we find a reason)
todd_ sorry to sound dumb, but is that another channel that I should move too? 20:20
mst that's where we're discussing improvements to installers etc. so you should probably be aware of it if the installers break
this is a module being weird
DrForr Not necessarily move to, but join if you're interested.
RabidGravy todd_, no you're fine
mst hrm, does panda keep a cache of sources? 20:21
hoelzro mst: I think it does in the state file
er, nvm, I'm dumb
that's installation state
I swear there's a projects.json or something that it uses
yup, there is 20:22
RabidGravy well the proxy code does "%*ENV<http_proxy> || %*ENV<HTTP_PROXY>" so you should be good if you have http_proxy in the environment
hoelzro it respects HTTP_PROXY? that seems a little scary 20:23
todd_ ok, then it is set correctly. wget, curl recognize it and I have pulled files through using it
RabidGravy hoelzro, ?
hoelzro don't some systems (like the obsolete CGI) set HTTP_PROXY from HTTP headers of incoming requests?
hoelzro isn't sure if modern things do this 20:24
I'm just visualizing a system that allows users to install panda modules via a webform or something, and an attacker injecting a bad proxy that would serve up bad modules
I'm probably just being paranoid
mst LWP::UserAgent's code traps $ENV{REQUEST_METHOD} 20:25
todd_ building useragent with --notests 20:26
Skarsnik RabidGravy, any idea why I have to explicitly-manage something so the lib pointing to the content is not lost? (I am not even done with the variable itself)
gtodd hmm I was always on very good terms with my sibling ....
todd_ moving back to install Task::Star 20:28
RabidGravy todd_, I don't think the code in H::UA for proxy support is very well tested tbh, it's kind of tricky to test without an actual proxy

RabidGravy yeah I think tadzik contributed the proxy code in H::UA explicitly to support the panda case
diakopter my ($proxy, $proxy-port) = %*ENV<http_proxy>.split('/').[2].split(':'); 20:34
well it doesn't support proxying SSL, that's for sure
when it says "Simple"...... 20:35
RabidGravy well neither does h::ua to be fair, need someone clever and motivated to do the CONNECT THING 20:36

dalek kudo/nom: af87982 | lizmat++ | src/Perl6/Optimizer.nqp:
At least temporary fix for RT #127207

Seems the optimizer thought that all Num values where actual numeric values and not abstract things like Inf or NaN. This patch (probably very badly) checks for that situation, and basically just emits the compile time error if it *is* an actual literal numeric value. Else it just ignores, and it becomes a runtime error.
Leaving it as an exercise to the more knowledgable Optimizer.nqp devs to make it go to the exception *and* handle the error in such a way that it won't suggest trying to coerce the value to Int/Rat/Complex first.
ugexe i dont think anyone questions that?

timotimo does somebody know a simple way to force a program to swap out pages when it hits a vastly lower RSS than it would usually have to? 21:48
lucasb acronym bot: resident set size (RSS) 21:50
moritz timotimo: google/stackoverflow says you can configure the swappiness per cgroup 21:51
timotimo moritz: well, swappiness, but i can't force early swapping when there's still lots and lots of ram left?
moritz timotimo: I'm not aware of a means to do that; why would you even want that? 21:52
dunno, does an ulimit for the RSS force swapping, or does it kill the process?
timotimo ulimit for RSS is a no-op in linux 21:53
i'd like to experiment with things in moar's GC that could potentially make moar more responsible when swapping is involved
21:55 joydon joined
geekosaur thinks the easiest way to trigger that is a virtualbox or etc. with a low memory size 21:56
timotimo probably is :\
RabidGravy yeah I was going to suggest that
timotimo i was hoping for a much less invasive way 21:58
El_Che what about running the moar in a docker container with restricted mem resources 21:59
moritz cgroups maybe?
El_Che a lot more lightweight
lichtkind is there a way to define a ternary sort operator?
RabidGravy yeah, docker you can specify e.g. tiny memory and huge swap
El_Che (docker uses cgroups btw) 22:00
22:00 llfourn joined
El_Che you may need to change the boot options 22:00

El_Che yes

RabidGravy docs.docker.com/engine/reference/r...-resources
El_Che moritz: you don't need docker at all, idd

hoelzro lichtkind: ternary sort operator? can you give an example of its usage? 22:02

RabidGravy toodles 22:44
lichtkind how hard is it to introduce a precircumfix category?
22:47 sena_kun joined
arnsholt You'd have to add it as a category the operator precedence parser 22:47
I don't think Rakudo customizes that, so it'd be in HLL/Grammar.nqp in NQP; the EXPR method
TimToady note that you cannot add a precircumfix that would be ambiguous with a term 22:49
you can't add precircumfix:<[ ]> for instance, since we already have circumfix:<[ ]> that is parsed in the same spot
sena_kun hi guys. I'm playing with NativeCall library and need some advices now. Firstly, how should I represent 'void**'? Something like "Pointer[Pointer[void]]" will be valid(it compiles)? 22:51
Skarsnik Pointer[Pointer] or just Pointer
masak it's not that precircumfixes are impossible, it's that they don't tend to happen in languages, I guess. 22:52
Skarsnik I should document nativecast x)
masak probably something to do with the order in which the reader expects things
TimToady in a sense, the reduce operator is already a precircumfix
22:52 lzlgboy joined
sena_kun Thanks. Also, I think that "FILE*" will be just plain Pointer also? 22:52
22:53 lzlgboy left, abraxxa left
Skarsnik Yes, if you do nothing special with 22:53
timotimo it's just a funky integer 22:54
22:54 yqt joined
RabidGravy sena_kun, yeah, but if you are use it a lot you can do "class File is repr('CPointer') { ... }" which means that you can add your subs in there and add methods that abstrat them 22:54
abstract
Skarsnik I am not fan of this pattern x) 22:55
sena_kun Okay, thank you. It's integer, but coercion can be tricky sometimes.
Skarsnik also I wonder how hard it will be to allow CStruct to have method
RabidGravy see e.g github.com/jonathanstowe/Audio-Lib...ut.pm#L388
Skarsnik, you can put methods in a CStruct 22:56
Skarsnik Oh I never tried
I think nc tell you that you can't
+doc 22:57
sena_kun Thanks for the link.

arnsholt Skarsnik: You're probably confusing it with CPointer, which can't have *data members* 22:58
Both CStruct and CPointer can have methods
RabidGravy it getss messy if you try *native* methods, but normal ones are fine
Skarsnik You can look at App::GPTrixie if you don't want to write too much NC code yourself ^^
RabidGravy it's even more fun with CPPStruct ;-)
arnsholt Oh, I take no responsibility for "method foo(...) is native {...}"
If you try that, you deserve what you get =) 22:59
patrickz timotimo: zef seems to work
RabidGravy github.com/jonathanstowe/Audio-Sou...uch.pm#L32 works fine :)
Skarsnik "Of course, methods are completely fine too. Go wild!" I can't read
arnsholt Basically, to use NativeCall you should be able to write the equivalent code in C 23:00
timotimo patrickz: cool.
Skarsnik I love this: has Pointer $!vtable;
RabidGravy yeah, it's odd, I guess that's what it is because it's out by one pointer without it 23:01
lichtkind TimToady thank you
TimToady, so i should use the prefix_circumfix_meta_operator category to make matrix norm ops? 23:02
23:02 muraiki left
RabidGravy and you only seem to need it if there are "virtuals" in the inheritance chain 23:04
Skarsnik Oh
I think cpp does something special for virtual
like adding virtual to a class keep it abi compat
Juerd lizmat: Why assign u32 *and* u16 *and* u8 in a union? Assigning anything other than the widest type makes little sense... 23:05
Skarsnik it's probably because of this ptr?
El_Che this is nice: thelackthereof.org/TLT/2016.01.08/...t_for_None 23:06
lichtkind thanks for link
i see some interesting parallels beween fortress and perl 6 23:07
RabidGravy El_Che, the colour scheme makes my eyes hurt, but yes 23:11

profan anyone have a reccomendation for a usable perl6 http client lib? 23:45
23:45 yurivish left
profan recommendation, even 23:45
came across HTTP::Client but was apparently unmaintained
23:46 zwu joined
flussence uses Net::HTTP 23:46
RabidGravy well, HTTP::UserAgent is maintained, it probably lacks some features but works
profan neat, will take a look at those two then 23:48
RabidGravy I've added stuff to it to the extent that I needed features for my own modules 23:49

RabidGravy profan, please do post any enhancements and/or issues you may have to the H::UA github so we can make it better 23:55
any advice about using it can usually be had here :)
23:56 yurivish joined
profan RabidGravy: will do, does it handle redirects yet by the way? 23:56
ie, some way to specify "follow when given a moved response" when doing requests 23:57
RabidGravy yeah, it's actually quite well tested in that regard
23:58 sena_kun joined
RabidGravy though, at this point I'm sure we haven't covered all the scenarios 23:58
profan so, it always follows redirects, or is there a way to specify that? 23:59
