ab6tract good *, #perl6 09:04
i ran into something interesting while working on the Sereal port last Friday
an array of Nums failed to smartmatch against an array of equivalent Rats 09:05
calling .perl.EVAL on the array of Nums would make the smart match work
i'm not sure how to craft a minimal example for this, because every approach i have used to reproduce would Just Work, except for the original test case based on a real Sereal blob 09:06
eg: " not ok 3 - ARRAY -- got: $[1.23e0, 4.56e0, 7.89e0]expected: $[1.23, 4.56, 7.89]" 09:10
m: say $[1.23e0, 4.56e0, 7.89e0] ~~ $[1.23, 4.56, 7.89]
camelia rakudo-moar 4b934d: OUTPUT«True␤»
ab6tract so, wtf?
09:14 spider-mario joined 09:16 bjz joined 09:17 xinming_ joined 09:20 xinming left
ab6tract too early for the heavy questions, maybe? 09:21
moritz ab6tract: what types do you get there? 09:25
ab6tract: are these "vanilla" Array objects, or parameterized? (Array[Num] or so)?
ab6tract moritz: they are vanilla. the data gets encoded in Sereal as a double and gets read back out through a C function that casts to double (NativeCall return type specified as num64) 09:26
09:26 mcmillhj joined
ab6tract JSON::Tiny and JSON::Fast don't seem to support Nums, and only pass back Rats (the expected result is saved into a json file when generating the corpus of Sereal files (p5 script)) 09:27
moritz m: my num64 $n = 1e1; say [$n] ~~ [1e1]
camelia rakudo-moar 4b934d: OUTPUT«True␤»
moritz m: my num64 $n = 1e1; say [$n] ~~ [10.0] 09:28
camelia rakudo-moar 4b934d: OUTPUT«True␤»
ab6tract moritz: indeed. exactly as happens to me: any attempt to get a non-ok result from $[1.23e0, 4.56e0, 7.89e0] ~~ $[1.23, 4.56, 7.89] fails
and even calling .perl.EVAL on the object (should be a no-op, correct) makes it pass
09:32 mcmillhj left
ab6tract so it's unclear how to even create a portable test case 09:33
i can work around it by calling .Str.Rat on the result from the read_double C call 09:34
(custom function we wrote for getting doubles out of a blob)
09:34 kurahaupo joined
ab6tract but that feels very much like a hack, because the expression works fine when i type it in manually! 09:35

so, that doesn't actually help in the end
psch well, it does help insofar the its probably not NC directly

masak dunno what you're doing, but it works here
ab6tract that's my point, masak. i am running into an error case
you cannot get those to fail smartmatch
masak are you sure your test is using smartmatching?
ab6tract yes
masak wait, you want them to *fail* smartmatching?
m: say 1.23e0 ~~ 1.23 12:10
camelia rakudo-moar 4b934d: OUTPUT«True␤»
ab6tract no, i want them to pass. and they pass when inputting manually
they only fail in the code that i am testing
but even the got and expected values will pass smartmatch when put in manually
and the code i am testing will pass smartmatch if i do $a_of_nums.perl.EVAL ~~ $b 12:11
masak what's the name of the assertion sub you're calling?
ab6tract but not if i do $a_of_nums ~~ $b
'ok'
masak aha, and the expression you pass contains a smartmatch?
ab6tract yup 12:12
masak how have the Nums been produced?
ab6tract from a C routine: github.com/ab5tract/Sereal/blob/pe...code.c#L86
masak the plotchki thickens
ab6tract here is the nativecall definition: github.com/ab5tract/Sereal/blob/pe...ve.pm6#L21 12:13
and here is the line of code that pulls a double from the buf
github.com/ab5tract/Sereal/blob/pe...er.pm6#L39
masak ok, I now urge you to golf this
like, down to something ridiculously small, like three lines of code
ab6tract really not sure how to golf something that needs an object file
masak you'll think of something, I'm sure :D 12:14
ab6tract doing it just with NativeCall doesn't trigger the same issue
masak right now there is too much code not contributing to the bug

tadzik whatever's in perl6.org/documentation/ is your best bet at learning it :) 12:32
kalkin- Is it true that TT is working on a Perl6 book?
naser I am feeling confused about this language, looks like an old yet new language, no books except few old ones.. 12:33
perlpilot naser: if the books you have found on amazon are "Perl 6 and Parrot Essentials" and "Perl 6 Now", the first is no longer relevant and the second is more of a Perl 5 book :)
kalkin- naser: What helped me a lot is reading learnXinYminutes and the docs. Anything beyond that, wouldn't be in a Beginners Book anyway. 12:34
This channels is also very helpful and filled with kind people 12:35
What I personally missing the most a Good Practice guide, to learn what is the Perl6 way to do this or that, but there can be a Good Practices guide, because now one really knows how Good Practices should be. 12:36

gtodd1 any heavy git users have an opinion on the best/simplest/safest way to maintain source control for an application developing and using/working with at the same time? 16:02

[Coke] tbrowder: what are you doing that can't find the source of p6 modules? 16:02
also, are you behind a firewall?
gtodd by that I mean say I'm writing a module and using it in an app ... eventually I will have a repo for my application based on Module.p6m and a repo for Module.p6m 16:03
16:03 rindolf left
[Coke] I would just start out with repos for both things 16:04
gtodd I was thinking of instead of pushing an pulling a ton up and down from bitbucket or github I could just have a branch "myapp" I switch into to add my own configuration etc. and then the main branch for the module itself ... 16:05
I guess if I'm going to go that way eventually I might as well do it now
and have two repos
jnthn Provided the module is in a folder and isolated, it's possible to extract its history separately using git filter-branch later 16:06
If you go the two repo route from the start, git subtree may help make it less annoying 16:07
gtodd ok ... I thought I could have a branch specific remote so when I pushed it would be automagically pushing the right stuff to the right place
it just doesn't seem big enough yet
jnthn Remtoes are always branch specific anyway :)
Well, uh
gtodd Oh good :) ... 16:08
jnthn Branches each have their own remote branch, and those might have different remotes
pmurias [Coke]: it should be possible to compile the runtime parts using the new javascript into the old version
jnthn I'd probably use subtree or something though...
Or just fix it later with filter-branch

sena_kun I don't see anywhere in the docs(grep too) usage of "=begin output". Why nobody used it over years? It seems to be a valid pod code. 20:05
hoelzro pochi: did it work?
sena_kun: that's the POD code for "example output of a chunk of code", right? 20:06
sena_kun hoelzro, sure.
pochi hoelzro: still compiling
hoelzro sena_kun: yeah, it seems like it would be very useful

tbrowder [Coke]: Sorry, when I first installed panda I tried to install a module (don't remember which) and panda couldn't find it. I just tried "panda install Linenoise" and it recognized it being installed. Sorry for the wasted bandwidth--looks like a non-problem now.
jnthn Sure, methods need an object to work on.
AlexDaniel jnthn: sure, I just hoped that it will be done for me
jnthn Ah. That's now how Perl 6 OO works :) 20:26
And if you do want that, closures are really compact in Perl 6.
hoelzro pochi: that's weird - a similiar patch worked for me
AlexDaniel yeah
jnthn {$x.hello} is quite a bit shorter than $x.^lookup('hello') :)
pochi hoelzro: You are right, it works on the 'my $a ...' example :-) 20:27
gfldex jnthn: .assuming is defined for Routine, that includes Method, but there is no easy way to call that method.
zostay tx0h, i'm not sure i understand the question, the call to template() in bailador takes a string (scalar) containing the template, doesn't it?
AlexDaniel jnthn: except that .hello is a multimethod in my case, and it seems like it will be a bit longer to preserve that
pochi hoelzro: but not on my actual usecase :-)

22:25 Rawriful joined
sena_kun Ah, I'm wrong, actually. 22:26
gfldex sena_kun: rakudo does all the parsing of the actual .pod6 file. It outputs the data structure in the gist. There are a few shortcomings that different renderers deal with in different ways. 22:27
sena_kun gfldex, ah, now I understand it. Thanks. Let's see... 22:28

gfldex i tried to build a round-tripping Pod::To::Perl6 for easy testing both of a renderer and the pod6 part of the grammer and got stuck. 22:30

sena_kun gfldex, I'm looking at Grammar.nqp now and it seems we have to extend it a little bit if we want it to treat `=begin output` in a special way. 22:32
Since internal parser treats `=begin something` as just plain paragraph, where all spaces and newlines are eaten. 22:33
gfldex sena_kun: if you want to dig into it, Pod::Block could do with a parent attribute and if filename/linenumber could be preserved it would make it much easier for renderers to complain about dupe index entries and other problems. 22:34
22:36 canopus left
sena_kun gfldex, I'm not sure my attempts can give some result, but I'll try to investigate it further. Also, I thought about the examples compilation: we can fix up at least two common-case problems in automatical way using grep. I'll prepare PR a bit leter, I suppose. 22:39

camelia rakudo-moar e411e5: OUTPUT«Array @a = [Any, [Any, 10]]␤»
gfldex that means you can use multi dim arrays but there is no constraint on the dimensions. If you need that you will have to implement that by hand. 23:37
m: my @a; @a[1;1] = 10; dd @a.pairs;
camelia rakudo-moar e411e5: OUTPUT«(0 => Any, 1 => $[Any, 10]).Seq␤»
gfldex also, .pairs and a few other methods don't do what they should. 23:38
