timotimo right, eqv also cares about exact types 01:06
tobs` it still doesn't quite work in my case: 01:09
m: class A { has $.name }; class X { has A @.arr }; my @arr = A.new(:name<z>); my $x = X.new: :arr(A.new(:name<z>)); say $x.arr.values eqv @arr.values; say Set($x.arr.values) eqv Set(@arr.values) 01:10
camelia True
False
tobs` m: class A { has $.name }; class X { has @.arr }; my @arr = A.new(:name<z>); my $x = X.new: :arr(A.new(:name<z>)); say $x.arr.values eqv @arr.values; say Set($x.arr.values) eqv Set(@arr.values) 01:12
camelia True
False
timotimo custom classes don't behave like value types by default
tobs` apparently it isn't even related to the type constraint on the has'd variable
timotimo at least i think that's what it does
m: class A { has $.name }; class X { has @.arr }; my @arr = A.new(:name<z>); my $x
camelia ( no output )
timotimo oops
01:13 kurahaupo left
timotimo m: class A { has $.name; method WHICH { ValueObjAt.new("A" ~ $.name.WHICH) } }; class X { has @.arr }; my @arr = A.new(:name<z>); my $x = X.new: :arr(A.new(:name<z>)); say $x.arr.values eqv @arr.values; say Set($x.arr.values) eqv Set(@arr.values) 01:13

01:15 p6bannerbot sets mode: +v kurahaupo 01:16 Grinnz left
tobs` huh, that's exactly my situation, but I have never heard of "value types" before 01:17
timotimo whether two objects with the same "things in it" are eqv by default depends on whether they act immutable or not 01:18
an array would use its identity (think: memory address, but constant) for keying 01:20
in sets and such
tobs` suddenly all my tests pass \o/

holyghost hi jmerelo, I'm debugging Game-Markov, it should be ready for next week 07:16

I'm full of ideas for it, by reading a bit 07:17
jmerelo holyghost: good luck 07:18

Reflow, de-indentation and some corrections
holyghost jmerelo: thx, Mathx-Chaos should be working, I've updated the functionality 07:20
07:22 andrzejku left, andrzejku joined 07:23 p6bannerbot sets mode: +v andrzejku
jmerelo holyghost: "should be working" does not mean what you think it means. 07:25
holyghost ok
jmerelo holyghost: it means "I have not tested it, but it looks OK" 07:26
holyghost: like Yoda said, "Do and don't, there is no should"
Either it's working, or it's not working.
holyghost the updated and same functionality works I meant 07:27
It has 3 tests that work 07:28
the rest also
jmerelo holyghost: it compiles and there are two tests, which work. That's the only thing we can say
holyghost: and the two tests compare a function with itself. No wonder it works.
is-deeply $corrdim.dimension($pop,$pop), $corrdim.dimension($pop,$pop); 07:29
holyghost there's a 3rd test on cpan
jmerelo holyghost: that, also, does not mean what you think it means
holyghost which works
jmerelo holyghost: for me, it means "It's releasing to CPAN stuff that is not on the repository"
holyghost the above test you mentioned compares numbers by the functionality of the same method 07:30
07:30 tmetro joined
holyghost I use is-deeply because of comparison between numbers 07:30
e.g. doubles or floats 07:31
07:31 p6bannerbot sets mode: +v tmetro
jmerelo I can't really figure out what it does. It's not documented, nor tested, and there's no main "Mathx::Chaos.pm6" module with documentation. 07:31
It apparently computes correlation between two things, which I can't figure out either 07:32
07:32 kurahaupo_ joined
holyghost It's chaos theory math 07:33
07:33 p6bannerbot sets mode: +v kurahaupo_
holyghost I'll write docs later on, after everything of Game-Markov works 07:33
07:33 kurahaupo_ is now known as kurahaupo__
jmerelo holyghost: Mathx::Stat is in better shape, since there's some stuff in the README.md, but still no "main" class file, very few tests. 07:33
07:34 kurahaupo left
holyghost ok 07:34
07:34 kurahaupo__ is now known as kurahaupo, robertle joined
jmerelo holyghost: far as I can see, same problem with tests there. You are comparing something that returns a scalar with itself. There's no way that does not pass. That's not a test. 07:34
07:35 p6bannerbot sets mode: +v robertle
jmerelo github.com/theholyghost2/Mathx-Sta...riance.pm6 07:35
holyghost I want to compare the scalars as the function has no bugs
scalar to scalar is just a number as I mentioned 07:36
jmerelo holyghost: that is a single function. It should simply be a function. Besides, you are not constraining the type of $xpop and $ypop.
holyghost: in general, if you compare something to itself, it's going to say it's true
You should compare some call to the expected value of that call, which you compute independently. 07:37
That's what tests are.
holyghost ok but they return numbers so they are the same and easily formatted for is-deeply
ok never mind
jmerelo holyghost: is-deeply compares objects. And you should compare the result of a function to the expected result, _computed independently_ 07:38
holyghost yes but if you return a decimal number, those tings stay the same
numbers matter in this
where you say you compare objects you compare numbers 07:39
so it doesn't matter for my is-deeply
jmerelo holyghost: you want to test consistency, right. Consistency is good. But you should also test that the returned value is the right one, because if you don't, the value could be consistent but wrong. 07:42
Geth doc: 4fc1be8803 | (JJ Merelo)++ | doc/Language/control.pod6
Extends the definition of blocks

To include the fact that classes also behave as blocks. Closes #2481		 07:43
synopsebot_ Link: doc.perl6.org/language/control
holyghost jmerelo: sure but in math packages you cannot just put in an ok test against a number as the test itself can fail because of your bitwise system, somewise incorrectly speaking, but if my method is inexact I cannot test against some number 07:44
jmerelo holyghost: yes, you can. You can write tests for approximate numbers. There's the is-approx test
holyghost ah
07:45 rindolf joined
holyghost which is the same thing again 07:45
is-approx is stupid in my tests of Mathx-Chaos
jmerelo holyghost: look at this: github.com/MattOates/Stats
07:45 p6bannerbot sets mode: +v rindolf
jmerelo holyghost: look at the tests: github.com/MattOates/Stats/blob/ma...relation.t 07:46
holyghost ok
jmerelo This is one test: github.com/MattOates/Stats/blob/ma...relation.t
is cov(@x,@x), variance(@x), 'Covariance of same values is equal to variance';
holyghost I know
jmerelo And then the rest.
Besides, if correlation and covariance are already tested, and documented, and everything, it's always better to stand in the shoulder of giants and use them. 07:47
andrzejku do you think that it would be possible in the future to have Perl6 compiled executable like in compile language to tweak performance?
07:47 huggable left
holyghost again, my tests are not dumb 07:48
jmerelo andrzejku: you can probably have Perl6 bytecode. That's it. Perl 6 works on a virtual machine, so it's difficult to generate machine code.
sena_kun as a packed moarvm with a script inside? likely yes, if enough hands or funds to do. :)
07:49 [particle]1 joined

andrzejku jmerelo humm, maybe question regarding history who took the decision as I read a Perl6 history the first ideas about Perl6 VM it was C++ based VM, and how that happend that finally you created a C one? 07:52
jmerelo andrzejku: _I_ definitely didn't create anything.
And if I remember correctly, the first compiler was created by Audrey Tang in Haskell
andrzejku jmerelo I read it in Dr Fogs book 07:53
07:53 domidumont left, ChoHag left
jmerelo andrzejku: I don't know what were the advantages, at the point MoarVM started, of C over C++. Probably speed, but historically, the first was PUGS 07:55

SmokeMachine pmurias: isn't await working yet? 12:22
Juerd Picking a nit: I find it much more readable with a bit of extra whitespace: 1, 155, * + 1 ... * > 200
If you don't like whitespace, redistributing it can also make it more readable: 1, 155, *+1 ... *>200 12:23
The whitespace in the original, "1,155,* + 1...*>200" makes it look to me as if "1,155,*" and "1...*>200" are grouped 12:24
lucasb ah, I think it's nice when whitespace follow operator precedence too
Juerd As if two lists are being added: (1, 155, *) + (1 ... * > 200), not that that makes sense :)
lucasb 2*3 + 4*5 instead of 2 * 3+4 * 5

eval_code.js is huge (74M), maybe it could get trimmed down 12:53

SmokeMachine what about save the eval_code.js on a service worker or at least on a local storage? 12:55
pmurias SmokeMachine: cloned it, working on making it build
SmokeMachine pmurias: would it make sense to use service worker to "save" the eval_code.js? 12:56
pmurias: or the old app cache
pmurias how would that help?
SmokeMachine pmurias: would not download it every time...
pmurias the big problem is that that it takes a lot of time to load?
SmokeMachine: isn't it cached? 12:57
SmokeMachine of course it should be cached... (sorry, I was trying to help to solve the lucasb's problem...)
but yes... its cached on my machine... 12:58

or any EVAL?

camelia {a => c, b => c}
hahainternet is there a nice idiom to avoid this unfortunate misstep?
timotimo yeah 17:19
hahainternet and create an array / list within the value, ie a => [<b c>]

pmurias SmokeMachine: when you are using MemoizeDOM, the code in it gets run
the Perl 6 compiler doesn't complain, the node.js V8 that does the eval complains 17:29
SmokeMachine yesy... you are right... maybe Ill have to transform it in a sub `get-document`
pmurias: no... I didnt get it... it would happen if it were on a BEGIN, but why is it running on node? 17:31
and why it works on 6pad?

masak mscha: that looks like a multidimensional array indexing to me. is that what you intend? 19:06
i.e. -- do you know that `;` means "multidim" in index brackets?
mscha masak: yes, that's what I indend, and it works fine, but not if one of the two indices is a Match object, then you get that weid error message. 19:07
masak mscha: you intend for the Match object to numify automatically? 19:08
mscha With one-dimensional indexing, it works fine with a Match object as the index.
Most importantly, the error message is confusing. It took me about 15 minutes to figure out I had to numify it.

masak you need to *both* choose to make the "status" into "Schedule", *and* to hit the big nice "Schedule" button (twice) 21:44

I also scrolled through the preview, and it looked OK
Xliff Is there a way to refer to the current file, in Perl6?
_FILE_, is it? 21:45
