awwaiid I did something like $data = from-json(slurp('data.json')); $grepped_data = $data.grep(*<foo> == 7); now I try $data.elems and get "This Seq has already been iterated, and its values consumed", though I can see into the data. What gives? 01:36
01:37 cognominal left
awwaiid $grepped_data.round gives me the count, as does +$grepped_data (forcing number context) 01:37
ah, 'say $grepped_data.WHAT' tells me it is a Seq. interesting. 01:38
hmm. putting this into @grepped_data instead of $grepped_data is doing interesting things... 01:40
right. I think I read about greps doing more Seq like stuff. alright, your silence has taught me a valuable lesson. 01:41

dj_goku et09: I don't use vim, but for some reason that was added to some perl6/doc files. 03:42
so I cleaned it up and submitted this MR: github.com/perl6/doc/pull/172
et09 dj_goku: it controls tab formatting in vim
may not be the worst idea really 03:43
of course i dunno what it's doing in the middle of the file
dj_goku et09: right, but it shouldn't be in the files. IMO
et09 scratches head
03:46 AlexDaniel left
dj_goku use a vimrc file local to your environment instead of adding it to files directly in perl6/doc. 03:47
et09 i'm not even aware of vim being able to interpret something like that 03:48
but (assuming that's what it is?) the benefit would be that people wouldn't be using different conventions for tabs in your files, which makes such a mess
strange

mayuresh hello :) 05:21
05:23 aborazmeh left
mayuresh just an off-topic question; is there any way to earn a livelihood by working "on" perl6? 05:24
instead of simply using perl6?
as a programmer!
llfourn mayuresh: there's a Perl 6 core development fund www.perlfoundation.org/perl_6_core_...pment_fund :) 05:32
mayuresh: but I think you can count the number of people getting paid on one finger! 05:33
mayuresh :D
llfourn and it's probably not enough :\
mayuresh hmnn
i am caught in a dilemma, on one hand, i have great interest in working on the 'pxn', but, since it won't fetch me my daily bread, i am leaning towards working on my other idea, a 'ai' network analysis tool. 05:34
llfourn pxn? 05:35
mayuresh pxn == Perl6 eXecution eNvironment
it's going to be an "interpreter" for p6 instead of a compiler + vm combo 05:36
llfourn mayuresh: sounds fun does that exist at all? 05:38
mayuresh llfourn, no, it does not exist yet, not even a concrete design.
just a whole lot of diagrams in my design book. 05:39
05:39 softmoth left
llfourn sounds like many years of fun then 05:40
mayuresh llfourn, just that working on 'pxn' will help me grow as a programmer
just can't figure out how to capitalize on the knowledge i'll gain

05:44 _28_ria left, _28_ria joined
llfourn mayuresh: have you worked on a language interpreter at all? 05:44
mayuresh i am currently self-training for the same
my instructor has given me the liberty to choose any language for my final project 05:45
the rite of passage as they call it. :)
the instructor is a nice gentleman from germany
who imparts me tech wisdom remotely :)
his name is mr. nils m holm
all through my 23 years in software, all i did was database oriented stuff. 05:47
while i like 'rdbms' oriented stuff, i hated the other languages required to do something useful with 'rdbms'.
around 9 months back i realized that is have accumulated enough funds to support self-training for actual computer science stuff 05:48
and that i can survive 36 months without earning a dime.
and then i started off pursuing the regimen outlined by mr. holm. 05:49
he writes excellent books on computer science.
you could check out www.t3x.org
llfourn mayuresh: good luck with your endeavor :) 05:52
mayuresh yeah, thanks. :)
it's very mind-expanding.
llfourn thinks for him starting to write a Perl 6 interpreter from scratch would be more mind-exploding 05:53
mayuresh don't worry about it, i have worked on crazy stuff like industrial robotics. 05:54
they are a lot more painful than perl6. ;)

brrt llfourn: that is.. quite nice, i can't actually get that to work easily in python 10:11
sort of a litmus test on feature coolness :-)
ollej I'm having an issue when using the URI module inside a Promise. Unless I've used the URI module before awaiting the result, the program never finishes. Using rakudo 2015.09.
I've boiled it down to the following example: await Promise.in(1).then({ say URI.new('www.example.com'); }); 10:12
llfourn brrt: hehe well at least it has an inbuilt date obj
ollej Does anyone have any idea what I'm doing wrong?
brrt not sure you're doing anything wrong there
it doesn't look wrong tome
10:12 andreoss joined

10:13 Ven left
llfourn ollej: rt.perl.org/Public/Bug/Display.html?id=126390 10:14
"The last example just hangs. As far as I can tell, I have to make at least one get($url) call outside of the promise for it to work.
brrt what's the source of the URI module?
10:15 Ven joined
ollej Yeah, sounds very similar. 10:15
github.com/perl6-community-modules/uri 10:16
llfourn bets LWP::Simple uses this URI as well
ollej Sounds very plausible.
llfourn ollej: github.com/cosimo/perl6-lwp-simple.../Simple.pm 10:17
would be cool if we could get to the bottom of this
RabidGravy that would explain why I couldn't replicate the problem CurtisOvidPoe rt'd with plain IO::Socket::INET code 10:18
ollej I'm using a Mac btw, installed Rakudo via homebrew. But I think I get the same when running in a Ubuntu VM.
RabidGravy it shouldn't matter
llfourn ollej: according to ticket it happens in linux distros as well 10:19
brrt mysterious stuff
URI.new doesn't seem to do anything but parsing
10:20 edehont joined
RabidGravy yep, confirmed 10:20
ollej Yeah, I can't see why it would cause an issue with the Promise.
RabidGravy no, neither can I 10:22
but it definitely does
llfourn same for me :| 10:23
10:23 Akagi201_ left
azawawi question, do we need to put a " use lib 'lib'; " in a p6 test always or not? 10:24
RabidGravy azawawi, probably not, it's partly superstitious as e.g. panda test will run the tests with -Ilib anyway 10:25
10:25 kid51 joined
azawawi what about `prove -Ilib -e perl6` ? 10:26
RabidGravy it's only useful if you're given to running the tests individually without providing the -Ilib yourself
llfourn even URI.new with no args hangs
10:26 andreoss left 10:27 Ven left, virtualsue joined
RabidGravy I'll update the ticket, lest someone goes off looking in the wrong place 10:27
brrt llfourn 10:28
it may be a lazy deserialization issue
llfourn brrt: with the grammar? yes that's what I was thinking
RabidGravy++ thanks 10:29
brrt no, just with the URI module 10:30
llfourn brrt: I mean with the new here: github.com/perl6-community-modules...Grammar.pm
from BUILD in URI
brrt oh, that's actually quite plausible 10:31
RabidGravy yep, it definitely is the same problem - hangs at "futex(0x711f5c4, FUTEX_WAIT_PRIVATE, 1, NULL ....)" just as the original example 10:32
10:32 virtualsue left
brrt so, it's a deadlock 10:33
10:33 chenryn left
brrt possibly because of EVAL 10:33

jdv79 that bug is funky
azawawi require Foo::Bar; Foo::xyz();
we used that a lot in Padre to speed up load time 14:07
lizmat moritz: I think the decont here github.com/rakudo/rakudo/blob/nom/...ray.pm#L39 is faulty
FROGGS azawawi: and this works? github.com/sergot/http-useragent/p...bbdc8777b5
jdv79 as long as you avoid threads its seems to lay dormant
FROGGS azawawi: why do we want to load Encode at runtime when we can load it at compile time?
lizmat FROGGS: because Perl 6 atm suffers from the basic delay in loading modules from P5 14:08
and in P5 you try to delay it to as late as possible
azawawi FROGGS: for the simple fact that other module will be using it. Hence test suites will be slower
FROGGS lizmat: yes, but this will change in a not too distant future
lizmat exactly
azawawi FROGGS: s/module/modules
moritz lizmat: possible. I can't really judge it.
lizmat I get one spectest fail in the zip-latest test

FROGGS azawawi: we will have precomp soon again and then your patch will slow things down
lizmat so it's checking the final value 3 times, rather than the intermediat :-(

[Coke] I have concerns about the new junction tests that are relying on .gist to check if something worked. 15:12
FROGGS would even eat the heart of a targ with TimToady if that would help...
[Coke] moritz: what's the difference between defined and .DEFINITE ?
moritz [Coke]: defined can be overridden (and Failure does it)
FROGGS [Coke]: the alternative is to check its boolification, which looses a lot of information 15:13
[Coke] moritz (.gist vs. .Str) I've disliked that since day one, but TimToady seemed pretty set on it.
pmurias .tell konobi I'm not really sure one I put the various compiled files in the package.json containing directory, how should the files be loaded 15:14
yoleaux pmurias: I'll pass your message to konobi.
[Coke] moritz: (search) doesn't need an annotation; need a landing page for the search results. it's complicated enough that making a dynamic site starts to make sense (rather than a precalculated static)
FROGGS I like gist/Str so much that some of my Perl 5 classes have a gist method I use for debugging
TimToady [Coke]: I decided some time ago that .gist and .perl should sort their output for unordered types, so those are fine for tests
FROGGS like, I can gist DateTime::Spans and DateTime::SpanSets (as graphs)
pmurias .tell should the user npm install -g nqp-js and the use Foo will be translated to 'require("nqp-js/Foo")'? 15:15

RabidGravy well the posting back is easy, the "round trip" you seem to be wanting is a higher level something like WWW::Mechanise 15:36
not so much a missing feature of the useragent as a missing module that might use it
itz_stmuk most of the pure perl6 web modules fail on a significant number of poorly encoded web pages in the wild 15:37
jdv79 RabidGravy: huh? fetching a form and posting it are for a UA.
RabidGravy fetching a form, yep. posting a form, yep. 15:38
the bit in the middle, nope 15:39
jdv79 what bit is this?
RabidGravy the bit where it understands the content that is returned, parses it, determines what it should post to and with what parameters and occasions that post 15:40
which is what I take it you mean 15:41
ugexe jdv79: i guess under some situations it does still work. but if you look at this bit of code you can grep `$has_precomp` and `$has_source` when the argument names are actually kebobed. so for the highlighted bit of code it will actually loads whatever defaults CompUnit has instead of what the block of code implies github.com/rakudo/rakudo/blob/nom/...pm#L34-L60 15:42

[Sno] jdv79: any opinions adding --sysroot and --sdkroot options to nqp/rakudo Configure.pl and support them right then? 17:14
pink_mist: thanks
RabidGravy cosimo, there you go all worky again 17:15
itz_stmuk [Sno]: you can pass through options to moar like this 17:16
rakudobrew build moar --configure-opts=--moar-option=--cc=clang36
17:16 Peter_R joined
itz_stmuk not sure if that helps 17:16
[Sno] itz_stmuk: doesn't ;)
has nothing to do with option-passing
itz_stmuk you probably have to hack stuff up then :P 17:17
[Sno] but thanks
sure, but I want to hack it in an accepted way, not against the people currently contributing
itz_stmuk I still suspect you can pass your flags in 17:18
[Sno] itz_stmuk: no way, it has nothing to do with flags for moar or nqp 17:19
TimToady literally, 決心 is "decisive heart"
[Sno] it has to do with invalid and/or incomplete directories being used
PerlJam [Sno]: we're kind of an ask-forgiveness bunch, so you may just want to hack it and see what happens from there. 17:20

TimToady yes, determination, resolution 17:21
[Sno] look, when you have an sqk-root in ~/workdir/tmp/sysroots/x86_64-linux and Configure looks in /usr/bin instead of ~/workdir/tmp/sysroots/x86_64-linux/usr/bin - it's gonna fail to succeed
itz_stmuk oh so you need to add path prefixes?
[Sno] itz_stmuk: it's not a prefix 17:22
17:22 CIAvash left
[Sno] because the prefix is /usr - the sysroot for target file system and sdk file system are local 17:22
itz_stmuk is a prefix in a general sense I didn't mean --prefix 17:23

n0tjack is there any benefit to using HEREDOCS over comments for commenting? 19:52
ShimmerFairy n0tjack: after =begin it has to either be one of the standard names, or a custom typename that's in mixed-case (at least one uppercase and one lowercase letter). all lowercase and ALL UPPERCASE names either exist or are reserved
RabidGravy story of my life
n0tjack ShimmerFairy: Sounds like I really should read S26 ....
[Coke] HEREDOCS are parsed as code.
19:52 edehont joined
PerlJam ShimmerFairy++ way better 19:52
ShimmerFairy n0tjack: also, you need a newline after a =begin or =for block to start the content, since after the name you can put configuration options
19:53 Mhoram joined
n0tjack configurable comments, I love it 19:53
PerlJam POD is not exactly comments though
n0tjack been a while since I used POD or anythign like it. I never really wrote public code, even in my p5 days
ShimmerFairy n0tjack: Pod isn't really referred to as "heredocs", that's a separate thing. And if you want Pod-style comments, I recommend the 'comment' block --- '=begin comment ... =end comment', '=for comment', or '=comment'
n0tjack no, I meant actual HEREDOCS 19:54
ShimmerFairy oh :)
n0tjack I'm trying to learn to organize and structure p6 code appropriately, using Project Euler as my MacGuffin 19:55

camelia rakudo-moar 271713: OUTPUT«The funny symbol there is used␤to simulate newlines for camelia␤This is a heredoc␤␤42␤»
n0tjack so in each script which implements a problem, I'm gonna want a comment which notes the problem number, URL, problem description
PerlJam maybe just use #`{} style comments rather than pod 19:56
n0tjack I'm also gonna learn use TEST; etc.
19:56 AlexDaniel joined
n0tjack PerlJam: Does that scale to making a .pm6? 19:56
ShimmerFairy n0tjack: ^^^ that q:to// above is a heredoc, a way of writing multiline strings in a more natural way. Pod stuff has nothing to do with that kind of stuff :)
n0tjack Ultimately I'm trying to learn to be a "real" p6 programmer, not just a private hacker
ShimmerFairy: I know, I used HEREDOCS already for my first p6 project (for sub USAGE()) 19:57
ShimmerFairy: I was wondering aloud if their enhanced flexibility has any advantages over POD for actual code documentaiton
PerlJam n0tjack: depends on what you want to do with the "comments" If you're going to extract them as documentation, you should use pod. If they are really and tryuly just commentary about the code, regular comments would be fine (IMHO) 19:58
s/tryuly/truly/ # odd typo
ShimmerFairy n0tjack: for documenting your code, Pod is the way to go :) You can also use #|[...] before or #=[...] after things to add Pod strings to declarations (called "Declarator Blocks" in S26, fyi)
n0tjack ShimmerFairy: thanks! 19:59
PerlJam: Well, I'm gonna throw away all this project euler code, i'm just using it to learn all the features surrounding actual programming
ShimmerFairy n0tjack: I think my confusion stemmed from the fact that 'heredocs' aren't really a commenting mechanism, so wondering if they work for that is a bit pointless :)

Make dd a little more useful for natives

If you specify dd $a, and $a is a native int or str, then you only get to see the value *without* the name. This is annoying while debugging. To make this easier, you can now specify natives as a named parameter.
   my int $a = 42; dd :$a; # Int a = 42
and by the magic of the :$var notation, we can now see the name.		 21:33

leont Given a list of scalars, and a list of lists of scalars, how do I merge one element from the left with all the elements from one entry from the right in an idiomatic way? 23:07
The best I have so far is (@left Z @right).map( -> @ [$left, @right] { ($left, |@right) })' 23:08

leont .map({ $_[0], |@$_[1] }) is shorter, but looks awful 23:10

RabidGravy the first looks fine, bearing in mind at this time of night I can barely see the sigils ;-)
