dha FWIW, it appears, on my system to find said secondary p6doc under /install/share/perl6/site/resources/ 00:00
BenGoldberg Funny. 00:01
Does it cache the found location somewhere?

ZoffixWin Wat?
dha I have heard rumors that books... may be in the initial stages of being sort of worked on. :-) 00:04
BenGoldberg - doesn't look like it.
BenGoldberg What happens if you have two instances of p6doc, and both are the type which searches for other p6docs? Does it infinite loop? 00:06
dha In fact, it *looks* like there can be multiple secondary p6doc programs, and the one in bin may give you multiple possibilities if there isn't one that matches your "criteria"
00:06 Xliff joined
dha I'm a little unclear on what the "criteria" are. 00:06

ZoffixWin [o]
Xliff -[o]? 00:08
ZoffixWin, that's a new one. ;)
ZoffixWin :D
sortiz dha, the files in site/bin are the standard CURI wrappers, the basic "criteria" are :$auth and :$ver 00:11
Xliff Hrm. WinCompose is not working all of a sudden. :( 00:12
dha Ah. Clearly my problem is that I don't know what a CURI wrapper is. :-)
sortiz CURI = CompuUnit::Repository::Installable. Part of perl6 repositories magic. 00:13
Xliff Weird. X-Ming was blocking WinCompose.
00:15 vendethiel left
dha All right then. So, to fix the problem of stuff turning up in p6doc -l that shouldn't (well, at least the ones I've noticed), it looks like a simple .d test in the wrapped p6doc will do. 00:16
00:16 TreyHarris left
sortiz dha, It is supposed that you can have more than one module with the same name installed and in a filesystem independent way. 00:16
00:16 chrisdotcode joined
dha The question is, where would one put it so that it would reliably exist in an installation? 00:16
sortiz You can't, these wrappers are template based and created at install time. 00:18
dha i. e. in github.com/perl6/doc/blob/master/bin/p6doc#L107 you could put C<next if $file.d> after line 111, and you'd no longer get X or the extra instance of Backtrace, which are caused because it's currently listing directories as well as modules. 00:19
Ok, but the fix needs to go into the program the wrapper calls, not the wrapper itself.
sortiz Yep, the file you need to patch is the one in perl6/doc/bin 00:20
dha so, could it be put in github.com/perl6/doc/blob/master/bin/p6doc and then when people install it, it would work?
sortiz Yes. 00:21
dha Aha. Ok. I guess I'll do a pull request at some point.

lucs Looking at some roast tests: EVAL q{ goto SKIP5; }; 01:05

01:06 colomon left, colomon joined
lucs Oh, searching in the IRC backlogs, it appears that labeled goto is not yet implemented. 01:09
Tough luck for me. 01:10
Xliff OK. Assuming I have the following C construct: struct A { B (*next)(Struct A *a) }
How would I handle that in NativeCall?
This doesn't work: class A is repr<CStruct> { has Pointer $!next; method next { my &func = nativecast(:(Pointer[A] --> B), $!next); ... } } 01:12
sortiz Xliff, Try: class A is repr<Struct> { has Pointer $!next; method next { my &func = nativecast(:(A --> B), $!next); func(self); } ... } 01:16

Xliff I wonder if I can actually use the mangled name in this instance instead of using nativecast on an unknown pointer. 03:33
0040b8c0 T _ZN23XQillaXQCImplementation21create_empty_sequenceEP20XQC_Implementation_sPP14XQC_Sequence_s

is symbol('_ZN23XQillaXQCImplementation21create_empty_sequenceEP20XQC_Implementation_sPP14XQC_Sequence_s')
returns uint32
{ * };
Worked.... I think.
Xliff now has something else to try.
The only problem here is how volatile that symbol name is. 03:44
BenGoldberg Inside of native(...) and symbol(...) can be expressions, not just strings. 03:51
AlexDaniel Xliff: It looks like you went through a lot of stuff with NativeCall. Please consider contributing to documentation, it will be useful to others.
BenGoldberg So, instead of writing that big huge string out, write some function which generates that string, perhaps by doing evil stuff with the compiler. 03:52

Xliff .tell BenGoldberg I'd have to figure out how C++ mangles its functions. That's a task for another day. 04:23
yoleaux Xliff: I'll pass your message to BenGoldberg.
04:24 vendethiel left
Xliff AlexDaniel: I am keeping notes, but so far I haven't found anything -REALLY- compelling to contribute. Once I have completed this task, I will definitely write something on lessons learned. 04:24
gfldex Xliff: that depends on the compiler you use, and there is no stable interface. You have to wrap stuff in extern "C" { ... } to get c-style symbole names.
04:25 geekosaur left, AlexDaniel left, geekosaur joined
Xliff gfldex, these are pointers to functions, not stable functions. That's why I am having to deal with the mangled names. 04:27
Trying to use nativecast() on the returned function pointers gives me this error: Cannot locate symbol '' in native library '' 04:28
Although I have had success with a simplistic example which does the same thing.
The issue here is that this is a C-lib that wraps CPP classes.
04:32 khw left
Xliff I may end up having to give this up and properly wrap the C++ classes. But that's at least an order of magnitude more work than trying to wrap these function structs. 04:35
(There are -way- more classes)

teatime So guys, can I be totally off-topic and ask for your aesthetic opinion on something: Are the 6x6x6 color cubes on the left side of this screenshot (xterm defaults), aesthetically superior or more useful, than the ones on the right (evenly spaced)? i.imgur.com/wyRpPJp.png 07:13
(I am trying to get to the "why" of why this palette was chosen as the default, and at this point I am suspecting it was an aesthetic choice.) 07:14
moritz teatime: well, for backgrounds I prefer the lighter colors, so the left palette; otherwise I prefer the right-hand side 07:15
teatime I tried to ask ##design, and ended up in an argument w/ one guy who insisted 0 - 255 ≠ 0x00 - 0xFF 07:16
nine teatime: could they just be gamma corrected? 07:17
teatime nine: yeah, I think that may be what it comes down to.
07:18 vendethiel left
moritz gamma rays! 07:18
teatime nine: basically, the default/left set is {00, 5F, 87, AF, D7, FF}³ and the equal-spacing/right set is {00, 33, 66, 99, CC, FF}³
Timbus its hard to tell though; our monitors are calibrated entirely differently. but for me the right palette is oversaturated and some of the reds blur together too much
07:18 zakharyas joined
teatime so the default/left set is spaced by {5F, 28, …, 28} and the right set is spaced evenly by 33 07:19
(all number in hex)
so, the left palette is just shifted to be lighter, basically. but I see the same as Timbus, so I'm thinking the point is for there to be more visually-distinct colors.
nine teatime: colors and brightness work non-linear. 0x66 is not twice as bright as 0x33
teatime nine: right.
nine The default/left just seems to take this into account 07:20
teatime nine: in fact, you could probably come up w/ an even better cube if you use different spacings for the 3 components; maybe based on CIElab space... but my actual/intuitive understanding of the details is very tenuous/non-existent.
nine: I'm pretty sure now that's exactly what was going on. 07:21
moritz also take into account that output devices had much worse quality back then
teatime (I should have compared them side-by-side long ago)

09:08 telex joined
teatime interesting. heh, psch, it took me quite a few moments to figure out the correct context for that (music theory) :) 09:08
at first I thought perhaps it was emacs.
psch oh 09:10
yeah, i suppose chord probably goes more towards emacs here, although i don't know what D5min would mean for emacs :)
teatime mode and chord made sense for emacs, but yeah D5min was throwing me :) 09:11
RabidGravy It's quite blues too
09:12 rindolf joined 09:14 Khisanth joined
psch well, my notation is not quite standard there. the number is the octave, which usually isn't mentioned iirc 09:15
but hey, at least it's not overspecific and only fails for D5min, it's apparently every Dmin in any inversion... /o\
but of course only in the mainline, and not an isolated test case 09:16
RabidGravy oh I see 09:17
teatime If I want to, given an input 24-bit RGB color, choose the closest from a set of 24-bit RGB colors, does anyone know a better way than xforming all of the colors to CIELab, and computing the CIELab distance between the input and each of the set of cantidates? Specifically, is there a better color space I should be using than CIELab, before I go to the effort of coding this. 09:40
09:49 arcetera left
psch ah, found it. apparently i didn't generate enough chords 09:49
see, from D5min i wanted to pick a new chord which has a root either m3, M3 or P4 away from the current one 09:50
that is, F, F# or A
but i only generated chords spanning exactly one octave...
jast teatime: depends. do you need to run the whole absolute colour space gauntlet in your use case?
psch so of course there's no chord on F or A (never mind F#, black keys are hard :P ) because the fifth and third respectively don't fit in the scale anymore 09:51
teatime jast: hrm, I don't understand? (I don't know much about this stuff.)
jast okay
teatime jast: but I do want the most accurate (visually) results, w/ no consideration toward performance.
jast basically colour spaces like RGB and CMYK are device-dependent 09:52
teatime right; presumably I can make some kind of reasonable assumption about which RGB space though?
jast depends on where your values are coming from 09:53
teatime I don't think I can make any assumptions about that.
jast many sources are just simply 'RGB'. if there's no definite mention of a colour profile in the source data, assuming sRGB or something like that probably isn't the best choice
and in that case you could simply convert to another device-dependent colour space like YUV/YCrCb for easier perceptual comparisons 09:54
sorry, that's YCbCr. I never remember the acronyms. :} 09:55
09:55 g4 joined
jast YUV or something comparable is used by most video and image codecs these days 09:58

teatime so that would be your recommendation? 09:59
over CIELab?

hahainternet a question, when generating a sequence, if you have a sequence function with arity of one, and you generate a number previously generated, would it be ludicrous to assume the sequence is cyclical? i think probably it's not provable 10:37
it'd be nice if where clauses / sequence blocks were a restricted subset so they could be more easily introspected without halting problems lol 10:38
arnsholt Not a good idea, I think
Consider for example a function that returns a random number each time
timotimo anything that has state, really
hahainternet arnsholt: indeed, hence why it'd have to be an introspectable subset of perl
arnsholt Basically, yeah
hahainternet you'd have to be able to know for sure it was going to repeat again, rather than having state or randomness
arnsholt In this context, introspectable subset would have to be "not Turing complete" 10:39
hahainternet indeed
timotimo the thing is, when you stumble outside that subset (or into!) of perl6 without noticing, you'll get unexpected behavior
10:39 Begi joined
hahainternet timotimo: perhaps, i personally feel it wouldn't be a bad idea to have a special block syntax for it, and then use normal blocks / function pointers for the rest 10:39

masak realization: because private methods are namespaced differently from public ones, I don't have to come up with a prefix (like 'internal-') or a suffix (like '-helper') when I name the internal private helper method :)
19:13 yqt joined
huf there's no namespacing when you grep :) 19:13
masak then you can grep for '!themethod' 19:14
jnthn Right, 'cus it's on callee and caller ends :)
huf oh, built in prefix :) that solves it then :)
masak I think we all love private methods at this point 19:15
I for one didn't expect to use them as much as I do
too bad they don't multi, though ;)
moritz now if they could be mul... what masak said :-)
jnthn Yeah. Especially when I reach for them in ES6 and...oh... :)
Yeah, I want them to be multi-able
masak jnthn: in TypeScript, you can basically have your multis
...kind of 19:16
jnthn I was talking about my privates, not my multis... :P
masak .oO( eww! )
jnthn o.O
It sounded like a cute play on your comment until I read it :P 19:17
I guess I hit upon missing private methods in ES6 'cus I was refactoring from code not using the class syntax. 19:18
Which would fake up private in various ways :)
But yeah, I'm very glad of private methods in Perl 6 :)
nadim Good evening everyone. is there a way to get the size of an object, like Devel::Size in P5?
jnthn nadim: It's very early and rough and ready, but you can use heap snapshots :) 19:19
And github.com/jnthn/p6-app-moarvm-heapanalyzer/ to query them
timotimo has a fork of that tool with more features also... 19:20
nadim I read your post about them but I mean at run time, not in a post analysis, except if snapshots do that and I didn't get it
hoelzro jnthn: I figured; I tried to add AT-POS to the punning exceptions list, which resulted in LTA behavior =)
jnthn hoelzro: yeah ;) 19:21
nadim jnthn: I mean to add it as an option to Data::Dump::Tree
jnthn nadim: Ah, then no
nadim Id there a Devel size in th epipeline?
jnthn Not from me, at least 19:22
nadim Then I'll find another thing to work on, I think I have alist of modules that i should write ... somewhere
jnthn Though in working on heap snapshots we'll probably have done all the hard work to have such a feature :) 19:23
Since we're adding ways to query object's memory use as part of that
It's Moar-specific though 19:24
ZoffixW Is there a list of what sort of native types there are in Perl 6? (I need it for an article)
I guess a better question is how to get a list of types not listed on docs.perl6.org/type.html ? I don't see int32 nor UInt in the list. 19:26

pnu: nope, declaring the dependency didn't help :(
pnu: actually, I don't see that it's installing either Bailador or DBIish during the push to heroku. maybe because they're part of Star already or something?
pnu: anyway, it's been a breeze to use the buildpack so far! great work! 20:11
MadcapJake got really distracted these last few days and is in the midst of writing a Forth in Perl 6 :)
masak now I only wish it had a newer version of DBIish so I didn't have to downgrade locally in order to continue... :)

I can update the base package. 20:14

ZoffixWin I don't suppose there's a way to make $!foo available in my roles, but not in the public interface of Bar, is there?
m: role Foo { method bar ($self:) { say $self!foo } }; class Bar does Foo { has $!foo = 'foobar'; method !foo { $!foo } }; Bar.new.bar; 21:39

ZoffixWin Good 'nuf for me
Juerd You can have 'self' without $ even if it's not in the signature. 21:40
Also, your method !foo could "is rw" if you like :)
ZoffixWin m: role Foo { method bar { say self!foo } }; class Bar does Foo { has $!foo = 'foobar'; method !foo { $!foo } }; Bar.new!foo;

ZoffixWin Oh, oops. Wrong code
Works. Thanks, Juerd 21:41

ZoffixWin So what does this mean "fully qualified"? Does it mean there's actually a way to call !foo in this case?
Juerd $x!Bar::foo gives another interesting error message. 21:43
sortiz ZoffixWin, yes, if the class 'trust' you.
ZoffixWin Ahhh 21:44
Thanks, all.

_ramix_ Hi. I need to know if the threads that can create IO :: Socket :: Async in a react can be killed from the process table after closing the connection. Is supported IPC in Perl 6? 22:48
thanks!
ZoffixWin _ramix_, you call done to exit the react block. That should probably do the trick. 22:51
22:51 cpage_ left
ZoffixWin Hm. In my code here, I see I call .close on the socket to end it: github.com/zoffixznet/perl6-IRC-Cl...t.pm6#L122 22:52
22:53 spintronic_ joined, vendethiel left 22:55 spintronic_ left
_ramix_ the react is a infinite loop. If I put a exit, the program finish. My intention is to implement a simple web server. Close the connection is not enough to kill the thread. 22:58

_ramix_ ok, I will try... 23:00
grondilu I vaguely remember someone having written a neat way to test the type of the elements of an Array. I wanted to do *.all ~~ Type but that does not work.
m: my @a = rand xx 3; say @a.all ~~ Real; 23:01
camelia rakudo-moar c8ec5a: OUTPUT«True␤»
grondilu jeez I thought that would fail
m:subset Vector of Array where *.all ~~ Real; say [1, 4] ~~ Vector; 23:02
m: subset Vector of Array where *.all ~~ Real; say [1, 4] ~~ Vector;
camelia rakudo-moar c8ec5a: OUTPUT«False␤»
b2gills you can't do *.all ~~ Type because ~~ can't be in a WhateverCode closure
{.all ~~ Type} should work
grondilu ok 23:03
m: subset Vector of Array where {.all ~~ Real}; say [1, 4] ~~ Vector; # just checking

ZoffixWin Check it out. Possible the first ever Tweet by a Perl 6 script: twitter.com/zoffix/status/717487486281388032
b2gills Now all we need is an irc bot that also does twittery things 23:04
23:04 arcetera left, lizmat joined
ZoffixWin Like what? 23:05
We do have a Perl 6 irc bot that almost works :)
grondilu now say I want to make a module which exports such Vector subset. Can this module be named "Vector" as well?

ZoffixWin 114 lines of code among 6 files for that tweet. And I had to do OAuth 1.0 signature stuff on my own. Not bad at all. 23:07

ZoffixWin What was the trick to return something concrete with a trait, rather than the sub body? I thought I saw something.
