Zoffix Well, I picked literally the most loved, highest rated font on Google Fonts and I thought that was a safe bet. The old typography used browser/OS defaults and looked like shit. Feel free to amend any of my changes. It was my best work and I've got nothing better to offer :) 01:05

sammers ok, quick question, what is the best type / value to represent nothing? Nil?
Zoffix Try pressing Ctrl+F5, if that doesn't help, ¯\_(ツ)_/¯
01:36 grassass left
Zoffix sammers, best type to represent nothing is nothing :) 01:37
sammers, why do you need to represent it?
sammers very zen
Zoffix huggable, Mu name
huggable Zoffix, "M"ost "u"ndefined. Or philosophical: "The nothing from which everything proceeds"
01:38 ssotka left, ssotka joined
sammers actually, no need at the moment. Just curious how to represent it in p6. 01:38
so Mu
hmm
Zoffix I wouldn't say so.
AlexDaniel Zoffix: ctrl+f5 does not help. Here Roboto Mono is crossed out and Open Sans is used instead 01:39
Zoffix Perl 6 has an infinite number of undefined values.
So use the most appropriate one if you have to

dj_goku Segmentation fault: 11 isn't really helpful when trying to debug NativeCall. I know it isn't Perl6 or NativeCall though. just sucks. 01:52

japhb sammers: Note that there is a difference between representing truly *nothing*, as in the absence of any value (Nil or Empty), and a value that is undefined, uninstantiated, or not part of the set of valid values of a type (represented in Perl 6 by the type object of a given type). 03:12
TEttinger nothin ain't nothin 03:13
japhb sammers: And note that Any is the type object used to represent undefinedness when the actual type doesn't matter much, but is a "normal" type, or Mu when you specifically want to say that the entire type universe is possible (so including special types such as Junction)
sammers ok, so for nothing, Nil or Empty. How would I check for a non-declared variable?
japhb If you try to use a non-declared lexical value, the compiler will complain. 03:14
sammers not undefined, but not declared
yeah, to avoid complaining
japhb m: say $foo; # sammers
camelia rakudo-moar 75b37e: OUTPUT«5===SORRY!5=== Error while compiling <tmp>␤Variable '$foo' is not declared␤at <tmp>:1␤------> 3say 7⏏5$foo; # sammers␤»
sammers like a catch
is that possible in p6? 03:15
or will the compiler always complain?
japhb You want to prevent the compiler from noticing variables aren't declared, or you want to declared them with use a la Python?
m: say $Unknown::foo; 03:16
camelia rakudo-moar 75b37e: OUTPUT«(Any)␤»
sammers well, this is just hypothetical at this point.
japhb If you explicitly use a namespaced variable name, the compiler will assume you know what you are doing, and allow you to load the footgun.
sammers thanks compiler
ok
japhb (as in the $Unknown::foo example above) 03:17
sammers yeah
I am just trying to think a scenario where I would want to reference an undefined variable without the compiler complaining.
I guess if I was dynamically creating the variable name
and testing for it later
regarding the Nothingness, I was thinkinb about "bottom type" and how it typically is handled in p6. But I guess (Any), (Str), etc. would be the most common 03:19
japhb Any is the default type for scalar containers if you don't specify something else, so you'll see that a LOT
sammers ok 03:20
japhb *type for the contents of a scalar container # to be more precise
sammers right

tbrowder jnthn: people were excited about functional prog after damian's several presentos at yapc, but then heard tail call opt is not in p6 yet. any kind of forecast? 10:09
jnthn tbrowder: No.
tbrowder: There's also a "tail call as a language feature" vs. "tail call as an optimization" thing in there also. 10:10
And those are different, and the first one is probably what you want when doing FP
Because "this might or might not introduce a callframe depending on the optimizer" isn't quite so useful :)
tbrowder i guess on concern was stack usage 10:11
jnthn Right, that's what you're trying to avoid.
gregf_ m: my @maps = <zero +ve -ve>;my @arr is Array of Int = -1,0,3; @arr.map: { my $ind = $_ <=> 0; say $_ ~ " is " ~ ( @maps[$ind < 0 ?? *+$ind !! $ind]) } # jnthn, was trying this 10:12

jnthn tbrowder: I think if we end up with something there, it'll be an alternate form of "return" that replaces the current callframe 10:13
tbrowder damian was also asked about any public doc on planned p6 features, todo lists, etc., and he said not to his knowledge, but mayby larry has alist written down somewhere 10:14
jnthn Well, also the design docs (synopses) are a good place to look in that they contain plenty of ideas that didn't make 6.c, but that are considered reasonable for the future. 10:15

Xliff jnthn: How much improvement (speedwise) is slated for the precompiler by 6.d? 10:26
Maybe s/slated/expected/ 10:27
jnthn Xliff: Those are unrelated. 6.d is a language version; it only implies things about features/conformance. 10:28
10:28 abraxxa1 left
Xliff Ah. So precompiling is more Moar? 10:28
jnthn Xliff: Naturally, by the time 6.d lands I'd expect there to have been plenty of performance work in Rakudo.
And Moar
Xliff (pun intended)
jnthn: Fair enough. Thanks! 10:29
jnthn Well, actually the improvements will come at all levels of the stack (Rakudo, NQP, MoarVM)
10:29 abraxxa joined
Xliff Ah! Good to know. 10:29
psch Xliff: syntax is a Perl 6 thing. performance is a Rakudo thing
jnthn I suspect when we do reach the 6.d point then we'll as part of marketting allow ourselves to blur the lines a bit.
Xliff psch++ # That actually helped! 10:30
jnthn++ # Always
Well, reason I was curious was because on current project, scripts take ~90 seconds before execution starts. 10:31
psch Xliff: put it in a module, export the MAIN sub :) 10:32
Xliff psch: Already in modules. :)
LOTS of modules, actually.
jnthn Yowser, that's ages
psch ...remove 'no precompilation'? :S
Xliff Hence earlier conversations on the subject. Particularly when you change the one module the others depend on.
And what 'no precompilation' :P 10:33

and from there ad infinitum ?

Xliff lizmat: That could be.
nine: Nope. Not that one. 10:39

Xliff All I know is that whenever I run into it, I try to gdb it to find out where it occurs, and all backtraces are deep into a repetitive gc cycle. 10:39
I tracked it back to the method signature, removed the type checking, and it went away. 10:40
I will git-bisect. I'm sure I have a recent commit where it is demonstratable. 10:41

sammers hi all 11:00
11:01 eyck joined
sammers Is there a way to create a namespace / package for a non class module? For example, using Class we can do something like: use Thing; my $thing = Thing.new(); say $thing.something(); 11:01
psch m: module Foo { our sub bar { "bar" } }; say Foo::bar 11:02
camelia rakudo-moar 50740b: OUTPUT«bar␤»
sammers ok, is there a way to use sub bar without ::? and not naked? 11:03
psch m: module Foo { sub bar is export { "bar" } }; import Foo; say bar 11:04
camelia rakudo-moar 50740b: OUTPUT«bar␤»
sammers we can do: use Foo; bar();
but I want to give it a prefix
like a Class does
psch why doesn't Foo::bar do that?
sammers like Foo::bar(), but... is there any other way to handle it?
yeah it does
but I was wondering what options are available to us 11:05
psch alternatively, you could use a class that you don't have to (or even forbid to) instantiate
sammers also, even with Foo::bar, simple bar is still available.
psch m: class Foo { method new { die "no" }; method bar { "bar" } }; say Foo.bar;
camelia rakudo-moar 50740b: OUTPUT«bar␤»
psch not if you don't export
m: module Foo { our sub bar { "bar" } }; import Foo; bar

11:05 eyck left
sammers ok, so Foo::bar would work, but not bar without is export... 11:06
ok
what about using another prefix, instead of Foo;;
Foo::
psch that would be maliciously confusing in my opinion

sammers yeah, that is interesting..
just trying to simplify as much as possible
Xliff You can even shorten it since I've added the die method. 11:09
11:09 eyck joined
sammers I like the interface, Foo.bar 11:09

Xliff ??
Link, please?
sammers in this section docs.perl6.org/language/modules#EXPORT but a scroll down a bit 11:11
psch m: module Foo { module Bar is export { our sub baz { "quux" } } }; import Foo; say Bar::baz 11:12
camelia rakudo-moar 50740b: OUTPUT«quux␤»

use Foo 'foo'; say foo.bar();
11:13 eyck left
Xliff Do you want shortname to keep the prefix? 11:14
11:15 eyck joined
sammers I just want to write a non-class module, but have interface with the Module subs like foo.bar(); 11:15
psch why? that'd just convince people that your not-a-class module *is* a class module? 11:16
sammers yeah, good point. I guess to see if it is possible.
Xliff I'm sure it's possible. It's just how much effort are you willing to put into making it happen. 11:18
If you want complete control over how this looked I suspect a Slang could do it. I haven't written one, though so I don't know how much work that would be. 11:20
11:20 eyck left
psch eh, you could probably hack together a ModuleHOW child that delegated methods calls to subs in its Stash, but that's kind of like reinventing pieces of a ClassHOW anyway... 11:21
*delegates
and, well, a big difference between a Module and a Class *is* that the latter can already contain methods and dispatch to them successfully... vOv 11:22
sammers hmm, yeah, no need for that. I just was kicking the tires a bit. Does anyone know of a good non-class p6 Module I can take a look at? I just want to see what a good implementation looks like. 11:23
11:23 kid51 joined

psch sammers: i think most contributors actually like the OO we provide, sorry :) 11:24
sammers yeah, I do too...
Xliff Sammers: Do you have a p5 example?
sammers I have nothing against OO and I have been enjoying p6, but I like to see what options are available.
Xliff I'm beginning to suffer from non-caffeine and non-sleep so my answers will start to get less useful! =) 11:25
sammers no p5 example that I can think of 11:26
11:28 eyck joined
sammers so as a rule should all of our modules stick to the p6 OO concepts as much as possible? it looks like that has become the norm. 11:31

  `built-in' seems more prevalent than `built in' so I added a hyphen as
well.		 11:36
Xliff sammers: You just want to see how many ways you can call a subroutine with a prefix, correct?
sammers gregf_: not really trying to accomplish anything. I am just trying to figure out how fully non-OO paradigms can be implemented. and what options are available.
right
like are there any examples of a fully fp module with usage? 11:38
or something completely procedural? 11:39
but somehow providing a namespace, which I guess Module does just fine with ::
11:39 huggable left 11:40 huggable joined
sammers and how would we go about using an OO module with one of these other paradigms? 11:40
psch however you like..? 11:41
i mean, 5 is an object already
Xliff sammers: I will say again, with Grammars (Slangs) you can redefine how the parser works. You could add a prefixing method of your choice. 11:42
psch m: say 5.HOW.HOW.name(5.HOW)
camelia rakudo-moar 2f0026: OUTPUT«Perl6::Metamodel::ClassHOW␤»
Xliff However, this is rabbit hole! Be careful!
sammers ha, Xliff, yeah, I am just asking to learn how much we can implement any single paradigm divorced from any other paradigm. 11:43
without too many hoops
psch you can't really, you can just ignore that the other paradigms exist
which is mostly a style choice
sammers ok, that is a pretty good answer
Xliff sammers: Right now you can use modules (::) or classes (.) 11:45
If you want something more esoteric, you will have to get creative.
And I mean creative.
sammers Xliff, ok, thanks. That answers my question.
Xliff sammers: yw 11:46
psch classes also can do indirect object notation
Xliff psch: ?

::('A').method? 11:47

sammers thanks gregf_, that brings up another question, is there a simple way to wrap a Module in a Class like your example? So for example, writing an OO app, looking to keep things consistent, importing a non-class module but want to use it like a Class... is there a simpler technique to accomplish that? 11:56
psch m: sub f($x) { say "doing things with $x" }; "foo".&f
camelia rakudo-moar 2f0026: OUTPUT«doing things with foo␤»
psch just pretend the subs are methods \o/
sammers yeah, but it brings all the subs in without a Method:: if they are exported for example. 11:57
sorry 11:58
psch there's a ticket about namespace pollution from export-happy modules somewhere...
sammers Module:::
ok, so that is what they are called.
EHMs 11:59
psch ...i literally just made that up?
i mean, the X-happy Y is a pretty normal english idiom, isn't it?
sammers yeah
trigger happy
I guess the only thing someone needs to define is the export to private ratio. 12:00
psch well, the ticket proposed an explicit way of limiting what you do import, no matter if there's a tag defined that covers exactly what you need 12:01
12:01 sftf joined
psch as in, even if there's no tags defined and DEFAULT exports literally everything, there would be a way to say "i only want those symbols, tyvm" 12:01
which i think sounds pretty reasonable, but i don't think anyone has started working on it
sammers ok

although i'm probably wrong..? :/
Xliff use Module :ONLY<foo bar baz>; # ??? 12:06
Of course, that would mean that the :ONLY tag then becomes unavailable for module writers.
tbrowder need help with: rakudo/nqp
Xliff Which is why I did it without the colon at first.
psch Xliff: did you look at the ticket? :)
tbrowder: what's up?
Xliff Yes.
I am saying the same thing. The only difference is minor hairs. 12:07
psch right, i like :SYM fwiw
Xliff LOL! Traitor! =)
tbrowder I'm trying an nqp script in the rakudo repo where rakudo was built and locally installed
Xliff :ONLY reads better, but I care not about the details of the mechanism... only that it exists.

Coz I'm looking at World.nqp... and I'm tempted... :p
psch pls no
if it's not exportable, nothing can export it
Xliff No no.
I was just asking.
Makes things easier. 12:25
Problem is, the way I see it, I would be special casing :ONLY in both "use" and "is export" 12:26
s/I would/someone would/ # Let's not get funny ideas, Xliff.
12:28 brrt joined
BrokenRobot Xliff: I'd expect the :ONLY to function as the way to create an export tag from the module *user's* rather than module author's side. I don't care if John McAuthor thinks &foo, &bar, and $meow must be exported by default. I only need &foo and I don't want my code to break if they decide to add new functions down the road 12:28

BrokenRobot Ahh :)
nemo nine: huh. what's the alternative then? 15:16
nine nemo: any benchmark you can put together in five minutes will be more useful. Bogomips stopped being comparable in the middle of the 90s 15:17
nemo nine: I was having fun comparing my RPI3 bogomips to the very first x86 I'd ever owned (one powerable by a modest solar panel, the other needing the power of a small village to match the bogomips)
psch well, the wikipedia article reads like it's somewhat (but limitedly) useful to compare cpus of a given architecture
nemo nine: m'k - so if I wanted to compare 2 totally different processors I don't have access to, what metric would I use?
psch that is, actual core architecture, not instruction set 15:18
nemo nine: i.e. - I can't run code on them. I just want to get a rough comparison
either for purchasing decision or just curiosity
geekosaur there is no such thing as a simple benchmark for such. you test your actual workload, or as close as you can get to it
nemo geekosaur: welp. given that's impossible, guess I'm stuck w/ bogomips in a situation like that then 15:19
geekosaur because even if the cpu speed is the same, you have cache, memory bandwidth, etc. to deal with
nemo and any reviews I can find
15:19 donaldh left
geekosaur and bogomips don't even try to deal with those, and moreover can't even be relied on for purely cpu loads (especially if you have hyperthreading enabled) 15:20
and if you can't test your actual workload then you're rolling the dice 15:21
nemo sure. but there's a difference between just blindly clicking "buy" on a random CPU and trying to get *some* information about it first 15:25
eh. dunno. seems dubious to me that bogomips have absolutely 0 value 15:26

nine nemo: there's websites publishing benchmark results for CPUs. Just google for the exact two models you'd like to compare and you will find them 15:29
geekosaur the original intended use for bogomips was to calibrate spin locks. even that minimal usage turned out to be unsafe and a source of kernel bugs on multiple processor systems. so at this point bogomips are computed and printed for no reason but to placate people who want to see the bogompis printed 15:30
nemo so. here's my only point... en.wikipedia.org/wiki/BogoMips#Pro...ps_ratings if you look at this list. the bogomips goes up over time. no shock. it's a measure of execution speed

BrokenRobot Xliff: the keyboard... Well, it works and is good to type on, but I haven't had a chance to make the extra keys work. They work -almost- fine on Windows; the copy/paste mode fails half the time, pasting the wrong thing. On Linux, the unofficial driver doesn't support those keys ATM and I didn't bother trying to hack them in, and worst of all, the keys don't work in a Linux running in a VM inside the Windows 16:38
host, despite them working in Windows host.
So, in summation, I haven't had the time to fix the extra keys, even though I like the keyboard without them anyway :)

Von_Cheam Hi, I'm having trouble installing the GD module via Panda; it appears as though it's failing testing because liblibgd.so can't be found. I have libgd-dev and libgd3 packages on my ststem (Ubuntu 16.04). I've posted the panda output to pastebin: pastebin.com/0LFkQE7r 18:54
Any help or suggestions appreciated! 18:55
timotimo seems like the gd module has "libgd" in its "is native" where it should be "gd" instead
Von_Cheam okay, I'm not super experienced with github or panda (or indeed programming..); is there a way I can maybe pull it from github, rename all the "libgd"s to "gd"s, and then have panda build from my modified version? 18:57
timotimo working on a fix

tbrowder basically what i've been doing is using a p6 script with the pod table of concern on it and inserting lots of debug print statements in rakudo/src/Perl6/Pod.nqp to see what's happening at each processing step. i now know where the problem is happening and believe i can fix it. most of today was finding out how to stringify stuff in nqp. and instrumenting 22:43
Pod.nqp. The repeated build install cycle slowed me down a bunch--there's probably a better way to do it but at least i'm getting comfy with pod guts..
i didn't make much progress with running nqp alone, so i took the higher road as a driver 22:44
timotimo i don't have a better way for you than the rebuild cycle, but i can tell you this much: when i last worked on the pod code, rakudo took at least two times as long to build the core setting :) 22:45

tbrowder on my laptop the build/install cycle was taking a bit under 3 minutes with bleed (from early this AM US CDT) 22:48

timotimo 3 minutes? that's rough 22:55
tbrowder well, i could fire up my big server but it heats up my study a lot; can i use 'make -j N 22:57
(oops) 'make -j N' for multiple cores? 22:58
timotimo that part of the build doesn't parallelize :( 22:59
if you're running spec tests, though, you can use the TEST_JOBS environment variable

tbrowder i mean i know i can but i think i saw some comment that "the build doesn't parallelize" 23:00

tbrowder thanks for tip on test env var
timotimo you know you can get an account on hack.p6c.org if you want to? 23:02

tbrowder how fast is the build/install cycle on hack.p6c.org? 23:15
timotimo i can have a look
Zoffix Stage parse : 61.660
mas+opt is another 17
timotimo i need to clone all that stuff 23:16
Zoffix: how about actions, grammar, world, and pod modules?
tbrowder well my laptop does that, the time i quoted was the whole process (make; make install) 23:17
Zoffix tbrowder, today I ran the build on 24- and 32-core boxes. The best time I got was ~42s for Stage Parse and a few secs for the rest of the stuff 23:18
Sadly, it's not that easy to make it run faster :( 23:19
timotimo i shouldn't compile moarvm with unlimited processes at the same time you're doing a measurement, i guess
Zoffix XD
zoffix@hack:~/rakudo$ time $(perl Configure.pl --gen-moar --gen-nqp --backends=moar; make; make install) 23:20

tbrowder um, my actual last run stage parse was 73 sec and total of 2m17s, not too bad all in all

ooops
Sorry
timotimo also, hack is under a *bit* of load from my fuzzing stuff :S 23:21
collect.p6c.org/ <- click on hack.p6c.org, then on cpu, to see it
on the bottom there's buttons for hour, day, week, month, year 23:22

kurahaupo Zoffix: 26% less time is ~34% faster. perhaps some reciprocals are needed 23:38

Zoffix Aren't "less time" and "faster" synonyms? 23:45
