00:14 autarch how can I handle a C library which added a certain function that I want to access if it's there, but not blow up if it's not
00:14 autarch ah, looks like it's a runtime error, that's good

00:21 vendethiel joined #perl6
00:23 jcallen I'm trying to build rakudo through a package manager (meaning that `make install` *must not* touch /usr, but rather $(DESTDIR)/usr, etc.), and seeing an issue with tools/build/ trying to write to /usr/share/perl6/repo.lock (and failing because of the sandbox).  Has anyone else been able to try to fix this? (I'm looking to try and create a patch, but the code involved is a bit convoluted)
00:25 huf joined #perl6
00:25 stmuk jcallen: I believe others had the same or similar problems in the last day or so
00:25 Psyche^ joined #perl6

00:32 flussence rakudo git already has... three different fixes for this. probably should put them into a 2015.12.1
00:33 jcallen ...why can't I find a link to rakudo git...
00:33 flussence
00:34 jcallen that was too obvious (except that I don't assume that github is the canonical place to find sources...)
00:36 orbus style question - what's the preferred method for module functions to communicate errors?  return false?  throw exceptions?  whatever the author feels like (like in perl5)?
00:37 geck jcallen: what distor are you packaging for?
00:37 orbus I'm writing a new module
00:37 timotimo what perlbrew invocation do you use to get a rakudo 2015.12 with perl 6.c?
00:37 jcallen geck: Gentoo
00:37 flussence orbus: fail() if it should be recoverable, die() if not
00:37 orbus hrmm
00:37 orbus okay, will go take a look at those
00:37 orbus I know die
00:37 flussence jcallen: already has rakudo ebuilds
00:37 orbus haven't looked at fail
00:37 geck I've been pondering building a rakudo software collection for RH distros
00:38 lsm joined #perl6
00:38 orbus yum/dnf repository would save people some time for sure
00:38 jcallen flussence: that's an overlay; I'm working on repo/gentoo.git :D
00:38 flussence oh, feel free to steal them then :)
00:39 orbus or really now that the spec is stable, lobby to get rakudo into distros
00:39 flussence (at least two of those workarounds were *because* I was trying to get it to build on gentoo, so the hard work's done for you :)
00:39 orbus but I have no idea how that works :)
00:40 geck orbus:easier to just put out a package
00:40 geck I mean, earliest it could get in is rh/centos 8
00:40 geck as far as the enterprise distros go
00:41 jcallen should we be using the system libffi or the included 3rdparty/dyncall?
00:43 geck http://pkgs.fedoraproject.​org/cgit/rakudo-star.git/ -> probably wouldn't take very long using that as a starting point
00:43 flussence I've been building things with both for a long time, spectest stuff has been fine, the only real issue is bundled libtommath because upstream hasn't taken patches for that yet
00:43 flussence (it compiles fine, but you get weird errors in printf stuff)
00:45 rindolf joined #perl6
00:45 mojca I can confirm flussence's observation about printf and libtommath; the problem is that MoarVM should not install the libraries at standard places
00:45 jcallen flussence: I'm referring to libffi/dyncall specifically as there is a choice between them :)
00:45 flussence ohhh... I've never noticed...
00:46 awwaiid I want to add another 'multi sub EVAL' for :lang<Python> support. When I put it in the REPL or a main .pl6 file it works fine; when I put it in lib/Inline/Python.pm6 (above the class Inline::Python) it does not. Any pointers?
00:47 flussence ergh, yeah there's a bunch of stuff leaking into /usr/include here. I better fix that...
00:47 awwaiid the failure is that I get the "No compiler available for language 'Python'" exception, as if I hadn't created the multi sub EVAL at all
00:50 sammers hello, is there a way to do multiple assignment from an array? Something like my $foo, $bar = [1, 2];
00:51 TimToady m: my ($foo,$bar) = [1,2]; say $foo; say $bar
00:51 camelia rakudo-moar 64a61a: OUTPUT«1␤2␤»
00:52 cygx joined #perl6
00:52 cygx awwaiid: your EVAL should look like this: multi EVAL(Cool $code, Str() :$lang! where 'python') is export { ... }
00:52 sammers ok, that is perfect
00:52 sammers thanks, and congrats on the release... having lots of fun.
00:53 awwaiid cygx: I just tried the 'is export' and it works! I guess the code in rakudo implicitly does that somehow
00:53 cygx awwaiid: the core is an outer lexical scope surrounding your program, thus no need to export
00:54 awwaiid cygx: the core?
00:54 cygx awwaiid: Rakudo's core setting, ie the stuff in rakudo/src/core
00:54 awwaiid cygx: oh. this file is src/core/ . I see
00:54 awwaiid cygx: cool, thanks!
01:00 bpmedley joined #perl6
01:02 orbus geck: presumably should try for both - custom repo for centos 6/7 and try to get it included in 8
01:02 TimToady though why we call something on the outside "core" is anyone's guess :)
01:02 TimToady it's more like "cladding"
01:02 orbus geck: although even then the custom repo is worthwhile because stuff in centos swiftly drifts out of date
01:03 awwaiid TimToady: is it like OCaml's "prelude" -- more or less a standard-lib?
01:03 dududuedu joined #perl6
01:03 awwaiid oh wait, you were refering to outer lexical scope. nevermind.
01:04 orbus alright... my module basically works but I'm too tired/lazy to write tests or upload to github
01:04 orbus maybe later
01:04 TimToady but we don't call it a prelude specifically because it is not in front, but around
01:04 lichtkind joined #perl6
01:05 orbus first, food
01:05 awwaiid TimToady: like being wrapped in a nice warm blanket on a cold day
01:05 TimToady or vice versa

01:21 timotimo that one dood on twitter who's been annoying, negative, uninformed and unhelpful is now claiming false advertisements because he can't apt-get or perlbrew install 6.0.0
01:21 TimToady but by the time I was in grad school at UCB, the professors there had already found counterexamples to all but one of his "transformational" rules
01:22 lichtkind yes but its just stupid to claim you had to be forced to introduce oo into perl 6
01:22 TimToady haters gonna hate
01:22 lichtkind yes we wanted fresh ones :)
01:25 lichtkind at least koleda go its own main line news item, which means it was even in the top level news feed here in germany
01:25 flussence I don't even bother engaging with 'em any more. If they want to hellban themselves into maintenance programming, that's their loss :)
01:26 lichtkind well its the discussion section under my article , i try to keep there at least informed answers
01:27 lichtkind have a wonderful night

01:43 kmj Hi all. This is my first bit learning perl6. I have a quick question. Is it expected that if I call a method on an object that within double quotes, that the method does not get called unless it is called with parentheses. For instance:
01:43 kmj y $file = "main.p6";   8 say "$file.IO.Str $file.IO.s";
01:43 kmj versus
01:43 kmj myy $file = "main.p6";
01:44 kmj say "$file.IO.Str() $file.IO.s()";
01:44 jdv79 yes
01:44 BenGoldberg joined #perl6
01:44 kmj Ok, thanks
01:45 TimToady yes, the only expression-like thing that can interpolate without trailing brackets of some sort is a bare $foo variable
01:46 TimToady well, unless you count {$file.IO.Str} as an expression-like thing
01:46 timotimo TimToady: and putting an extra % in front :P
01:46 TimToady but in a sense that has trailing brackets too :)
01:46 timotimo m: my %foo = hi => "wat"; say "%%foo"

01:58 timotimo ^- could be ... useful? :P
01:59 [Coke] ENODALEK?
01:59 Hotkeys oh
01:59 Hotkeys why <?
02:00 Hotkeys on the code block
02:01 shicheng Greetings! Just heard the new Perl 6 release :)
02:01 TimToady we just heard about it 3 days ago ourselves :)
02:02 timotimo Hotkeys: turns it from something similar to <$foo> (interpolates regex) to something similar to <?$foo>
02:02 timotimo is <?foo> actually a sensible explanation for this?
02:02 [Coke] I tell you, we were all kind of surprised.
02:02 halto joined #perl6
02:02 shicheng Besides more neat syntax, does anyone has a sense about what kind of purpose that the new release could serve?
02:03 Hotkeys So basically it lets the regex match the truthiness of the code rather than just evaluate the code itself? @ timotimo
02:03 mst shicheng: perl6.c is a final "backcompat changes are considered bugs" release of the lnaguage
02:03 mst shicheng: that difference in policy is important
02:03 [Coke] wendy wrote up a nice article on "why use perl6"... but I don't remember where it went.
02:03 mst like, hugely important
02:05 shicheng Code: I would be very interested to read that article
02:05 shicheng Sorry.. [Coke]
02:05 [Coke] ah, found it:​-would-you-want-to-use-perl-6-some-answers/
02:06 mst of course my answer is basically
02:06 timotimo Hotkeys: the return value is the important distinction
02:06 shicheng mst: so does this mean it has a totally new design (which breaks backcompagt
02:06 mst 1) because perl5 OO with Moo/Moose is so much better than python/ruby/ES6 I can't use them without getting annoyed
02:06 shicheng backcompat
02:07 mst but perl6 is if anything even better
02:07 timotimo if you have a <{ ... }> in your thing and it returns something like "...", it'll be interpolated so that it matches three characters
02:07 mst 2) becauee grammars are amazing
02:07 mst shicheng: perl6 and perl5 are different languages
02:07 timotimo whereas <?{ ... }> will pass or fail the match at that point (but still let it backtrack and try again) if the return value isn't True
02:07 mst shicheng: perl6 has Inline::Perl5 that allows native use of perl5 code in perl6
02:07 mst shicheng: perl5 has Inline::Perl6 that allows native use of perl6 code in perl5
02:07 Hotkeys timotimo: alright, thanks!
02:07 mst shicheng: so "backcompat is totally broken but all your stuff should still totally work together"
02:08 shicheng mst: I see, I will keep this in mind
02:08 mst shicheng: i.e. you can run both in the same process, so the fact they're different languages in the same family actually isn't a disaster
02:08 * [Coke] wonders how to check on the build progress on
02:08 mst shicheng: I rather like this as an approach tbh
02:08 timotimo​/what_are_haskellers_opinioncritiques_of_perl6/
02:08 shicheng I am excited to see this classic lang got a new totally release, was too afraid of grammar difficulty to study it
02:09 mst shicheng: think of perl5 and perl6 as like lisps
02:09 mst shicheng: except with excellent bidirectional interop
02:09 shicheng with same spirit
02:10 shicheng On official website it says "It is going to serve for next hundred years."
02:10 shicheng What does that mean? I am curious ;)
02:10 mst shicheng: note I'm mostly a perl5 hacker, but perl6 grammars are likely to drive me to use Inline::Perl6 anyway
02:10 mst and I'm proud to be part of a community that cares about the bidi interop thing
02:11 xpen joined #perl6
02:12 leont Having written two non-trivial grammars (TAP and YAML), I agree with the grammars are awesome sentiment (YAML itself however…)
02:13 gfldex shicheng: Perl 6 is ready for the next 100 years because the grammer of the language is extensible and the language as a whole is planned to be extended by the user
02:16 jdv79 that's assuming people still code 100 years from now

02:30 timotimo it was monday and i totally forgot to work on the weekly :S
02:30 flussence if you hadn't said anything nobody would've noticed :D
02:32 [Coke] doesn't seem to be rebuilding; it did seem to have a build yesterday, though.

02:32 mst timotimo: I can't stop it annoying you, but I can say that your productivity overall is such that I'd defend the omission ;)
02:34 timotimo i watched congress livestream and played disgaea 5 :P

02:37 flussence well we've got the next 11.5 months free to write one that isn't outright painful to use...
02:37 mst not it, but I totally hope I'll help make it easier to deploy ;)
02:38 mst (this is me not promising anything, but saying toolchain stuff here so far has been fun so I'll hopefully keep getting sucked in ;)
02:38 mspo timotimo: you can always keep blogging
02:38 timotimo i'm surprised & glad you're enjoying working on our toolchain
02:38 timotimo mspo: yeah, i'll just blog something very interesting and also fun every day ... because i've already been so good at delivering the weekly on mondays ...
02:39 timotimo i didn't even work on the perl foundation perl6 wiki one bit today either
02:40 timotimo anyway. now is bedtime.
02:40 timotimo good night!
02:40 flussence o/
02:40 * flussence gives this dumb hacky moar header cleanup fix another shot
02:40 mst timotimo: I am the right sort of masochist to enjoy this, it appears. and long may it continue to seem so to me, since that way I'll keep doing useful things ;)
02:41 mst flussence: remember the mantra: "this is systems. you appear to be trying to be clever. stop." - so dumb+hacky may be the right thing
02:41 mst flussence: also, if you can reduce it to a perl -pi -e or similar, include the hacky script in the commit message for its application, then people can see exactly what you did and tweak it later if required
02:43 flussence long story short: moar bundles libs. moar provides an off switch, but the makefile force-installs the header files for them anyway. my hack right now is to just rm -rf those bits from $DESTDIR before it gets plonked into /usr
02:45 flussence ...which works *great* up until trying to build rakudo, because it needs some of those headers. whoops.
02:45 flussence surprised nqp and its sanity tests don't mind, though
02:46 cygx flussence: nqp doesn't require extension ops
02:46 mst flussence: yeah, I figured it'd be like that
02:47 mst first, however, I need to hit rakudobrew with a shovel until I can write tests
02:47 mst also I totally had another thing to write between christmas and new year
02:47 mst going to try and spend time on both but
02:51 flussence .oO( geez, I was a normal user last week... how'd I end up doing all this?! )
02:51 mst flussence: I hadn't even done anything until two days ago and then you broke something and I was bored :P
02:51 mst flussence: welcome to the perl community. this is why I'm here.

03:26 awwaiid you get to keep both halves
03:26 autarch PM me for the address to send money to
03:28 [Coke] autarch: I'm trying to build the site. It's possible the build process has gone wonky.
03:28 autarch maybe best to restore from backup for now? if such a thing is possible
03:28 [Coke] I think the process is also not happy if it takes more than 5 minutes.
03:31 Hotkeys did disappear
03:31 Hotkeys I can't access any of the pages
03:31 Hotkeys except the main pages
03:31 gfldex Hotkeys: yes, there is a cronjob so it might resurface in a bit
03:31 awwaiid taking 5to6-nutshell.pod and s/Perl 5/Ruby/g is amusing.
03:31 Hotkeys ah
03:31 [Coke] it would super awesome if the build process didn't take more than 6 minutes and counting. :|
03:32 gfldex the last time i tried to htmlify.p6 on my not so fast linux box, it took 90min
03:33 jdv79 any ideas on what the hot spots are?
03:33 [Coke] no, because it chokes the profiler.
03:33 gfldex anything really. It's not doing any concurrency
03:34 gfldex and it takes the $=pod content and transforms that into some intermediate format
03:34 gfldex i made my own pod2html (that does a lot less) and it takes 1m3s to generate the html
03:35 Hotkeys even with the long build times, does it need to remove all the docs mid-build?
03:35 Hotkeys or is it a "it doesn't need to" situation
03:35 gfldex it should not do that
03:36 gfldex and it didn't do that in the past, so there might actually be something very wrong, like a partial build that didn't fail loudly
03:37 Hotkeys ah, fun
03:38 [Coke] as I said, I was trying to force a build, since it was not building.
03:38 gfldex Use of the 'unpack' method is experimental; please 'use experimental :pack'
03:38 gfldex that's what it says locally

04:00 [Coke] wow, even the profile output from autarch's pod to html's basic.t is choking my copy of chrome.
04:00 * [Coke] wonders if he has to try to another upgrade there.
04:00 autarch [Coke]: yep, had the same problem
04:00 autarch I really think the profiler output needs some rethinking - JSON is not a great format for huge amounts of data since you can't really parse it from a stream
04:01 autarch although even with a format that doesn't require "read everything and parse it all at once" I wonder how perl6 would handle huge amounts of data
04:02 [Coke] is it json that is parsed and turned into code, or is it interpreted as raw JS?
04:02 [Coke] it's been a while since I poked.
04:02 [Coke] json.parse... yah, that'd do it.
04:02 autarch but what I mean is that you have to parse the whole data structure before you can do anything with it
04:03 autarch as opposed to something where you could build up your internal representation as you stream in data
04:03 [Coke] autarch: one possible thing that might help is making something that's a data structure, not just a bunch of keys/objects. (keep the size of the giant object down)
04:03 autarch that said, none of that matters for the web browser
04:04 kaare_ joined #perl6
04:04 autarch I kind of doubt there's any way to make something where the profiler lives in JS only for large programs - my profile of htmlify.p6 --sparse=20 was 83MB
04:04 autarch nytprof handles huge files that reasonably well, in my experience
04:04 [Coke] TimToady: 6.41% of the time in this basic.t test file is in sink-all
04:07 [Coke] autarch: does it surprise you that basic.t created 34K+ Scalars?
04:08 autarch [Coke]: heh, yes, it sure does!
04:09 autarch I didn't think the code I wrote was particularly egregious - it's not super optimized but I don't think it's doing anything crazy awful
04:10 [Coke] hurm. I am using the INSTALLED versions of the lib in the test. one sec.
04:11 autarch [Coke]: I just ran a profile and I see the same results as you
04:11 autarch it all seems to be happening in m-CORE.setting
04:13 [Coke] I imagine if we could cut back the allocations, that'd kill some GC that's going on...
04:13 autarch which I now realize is just a concatenation of all the core code
04:14 [Coke] OOC, why did you make the attributes Cool and not Str?

04:17 autarch [Coke]: oh, you're asking me

04:17 autarch ah, because I thought people might end up passing things like match objects or something along those lines
04:18 autarch maybe it should be Stringy?
04:18 autarch honestly, I'm just guessing at a lot of things ;)
04:18 [Coke] I would start with the simplest thing that passes tests, and Str seems simpler.
04:19 [Coke] You can define the methods that take them as coercing to str, so they can pass anything with a .Str method.
04:19 autarch ah, yes, that's what I want to do
04:19 autarch how do I do that?

05:27 yurivish What does it mean when an array's .perl representation prints as $[1 2 3]? I'm trying to zip two of these together and they're being treated as single elements. I guess it's somehow a "scalar containing an array", but what do I do to turn it back into a regular one?
05:28 skids yurvish: put an @ or | in front depening on what you are doing.
05:28 yurivish This has come up in using JSON::Tiny; I'm trying to process some results I got from an http request. Right now I'm assigning two json arrays to two @array variables, which turn out to be "scalars containing arrays" instead
05:29 yurivish skids: thanks! I can paste some code here to show you what I'm doing.. What's the best way?
05:29 skids probably
05:31 yurivish​ivish/4a70b891f6ffc17bb0ba
05:31 yurivish the $json.perl line prints an array starting with $[
05:32 skids yurivish: that would mean it's a Scalar containing an Array which would be normal.
05:32 skids It is the Z line you are expecting to work differently?
05:33 yurivish Yeah – I'm expecting @competions to be an array, @scores to be an array, and the Z line to return a list of pairs ((completions1 scores1) (completions2 scores2) ...).
05:33 yurivish but it seems to return ((completions scores)) or something similar
05:34 skids do @completeions and @scores have $[?
05:35 yurivish skids: Oddly, they have [[ and ]]. Hadn't noticed that before.
05:36 skids yurivish: that would mean they are arrays of arrays and you may need to either de-index or flatten.
05:37 skids Also normally, Z will return a ist of lists so the resulting array will be an array of the tuples.
05:37 skids m: perl6 -e 'my @d = [1,2,3]; @d.perl.say; my @e = @d Z @d; @e.perl.say

05:38 yurivish okay, I'm now trying to figure out where the second layer's coming from...
05:40 yurivish Aha, so $json is a Scalar containing an Array. The second element of $json is itself an Array. When I grab it and print it via say $json[1].perl, it prints as a scalar containing an array.
05:40 dalek specs: 94357cc | (Aleks-Daniel Jakimenko-Aleksejev)++ | S99-glossary.pod:
05:40 dalek specs: Typos, markup corrections, trailing whitespace
05:40 dalek specs: review:
05:40 yurivish When I printed $json.perl, it only showed a $ around the outer array and not any of those inside the json
05:41 yurivish Apparently indexing into any scalar containing an array has that behavior
05:42 skids Right the inside of an array is autmoatically scalarized so the $'s do not show.
05:42 yurivish so when it goes to convert that to an array (or whatever it's doing) to assign to an @variable, I'm guessing it's wrapping it in another layer?
05:42 skids No it's just you ca't see the $'s
05:43 skids m: my $d = [1,2,[3,4]]; $d.perl.say;

05:45 yurivish What do you mean when you say that you can't see the $'s?

05:46 camelia rakudo-moar 16c5fc: OUTPUT«$(1, 2, (3, 4))␤(3, 4)␤»
05:46 yurivish Right, I got that. But why is it that my @a doesn't print with a $ prefix on the inner array?
05:46 skids It is assumed behavior, just one of the things you have to learn.
05:47 skids (Compared to the other ways of doing it, it was a less anoying wart)
05:47 yurivish okay. might be one of those things a bit over my head for the moment. Just started playing with perl 6 a few days ago and haven't programmed in any Perl before. Thank you for helping me!
05:48 yurivish Is the best way to not get the "nesting" to flatten the array afterwards, or is there a way to avoid it in the first place?
05:48 skids Actally it was over the head of everyone until after several attempts to work out the wrinkles in the least incosistent way :-)
05:48 skids Well in this case you are working with a module so using flat when you assign is probably good.
05:53 labster "Type Bool does not support associative indexing."  Well, that's a new one.
05:53 skids Actually in this case I think you need | not flat.
05:55 skids m: True{4}
05:55 camelia rakudo-moar 16c5fc: OUTPUT«Type Bool does not support associative indexing.␤  in block <unit> at /tmp/xIj5BHPm8y line 1␤␤Actually thrown at:␤  in block <unit> at /tmp/xIj5BHPm8y line 1␤␤»
05:55 yurivish so I fixed it by using := assignments everywhere to peel off the outer wrapping. No idea if this is terrible, but it seems to work?
05:56 skids That will mean you are directly accessing the returned array, so if you utate it, it will change.  If that's OK it should be fine.
05:56 yurivish I couldn't quite grasp how "flat" was the thing I wanted since what I have is a JSON structure of the form [..., [1, 2, 3], ..., { 'thing': [4, 5, 6], ...}]
05:57 yurivish and I want to zip [1, 2, 3] with [4, 5, 5]
05:57 yurivish and the json data comes wrapped in a $[..., [1, 2, 3], ...] when I get it from from-json
05:57 yurivish wrapped as*
05:58 skids It's because $s[1] is behaving like $s[0..1] woud just with one element.
05:58 skids The $ protects from flattening.
05:58 yurivish I see
05:58 skids If it was in an @0sigiled variable it would not be protected.
05:59 skids @-sigiled, that is (I hate this keyboard)

07:56 orbus oh great #perl6, I seek your wisdom once more
07:56 orbus if I'm writing a module
07:56 orbus and I have custom exceptions in it
07:56 orbus is there any way to export them so they show up in the X:: namespace like the docs suggest they should?
07:57 orbus I tried naming them like X::MyModule::MyException
07:57 orbus but they then come out in the main program as MyModule::X::MyModule::MyException
07:57 orbus which makes sense but was not the desired effect
07:58 orbus or is the X:: namespace really just for the built-in exceptions and I should just put custom ones in my module namespace?
07:59 labster The X:: namespace is definitely the right place to put your own exceptions.
07:59 orbus okay
07:59 orbus that's what I thought
07:59 orbus now... how to do it
07:59 orbus I thought I was doing it right until I tried to catch one in the main program
07:59 labster use Module::Name;
07:59 TimToady did you put 'is export' on them?
07:59 orbus yup
08:00 orbus that was the first thing I tried
08:00 labster what error did you get, orbus?

08:03 camelia rakudo-moar 16c5fc: OUTPUT«HERE␤True␤»
08:04 orbus shouldn't it be my class X::Foo is Exception is export?
08:04 orbus I apparently have some other bug in my code I need to iron out first btw
08:04 TimToady well, I was just testing the exporting
08:05 orbus will have to come back to deal with the exceptions
08:05 orbus well
08:05 orbus let me try another script I had that was acting up
08:05 TimToady m: module Mine { my class X::Foo is Exception is export { method bar() { say "HERE" } } }; import Mine; say
08:05 camelia rakudo-moar 16c5fc: OUTPUT«HERE␤True␤»

08:06 TimToady hmm
08:06 orbus like CATCH { when X::Foo {.resume} }
08:06 orbus it was acting like it didn't know what X::Foo was
08:06 TimToady m: module Mine { my class X::Foo is X::AdHoc is export { method bar() { say "HERE" } } }; import Mine; say => "stuff").message
08:06 camelia rakudo-moar 16c5fc: OUTPUT«stuff␤»
08:06 TimToady it really is an exception there

08:11 [Tux] same, still over 15 :(
08:13 orbus now I'm seeing something even weirder

08:20 camelia rakudo-moar 16c5fc: OUTPUT«x␤caught␤»
08:20 orbus okay, so that works - at least here
08:20 orbus so maybe I"m doing something wrong in my other code
08:20 orbus saw something else weird though
08:21 orbus m: module Mine { my class X::Foo is Exception is export {} }; import Mine;  sub blah {say 'x'; die; say 'y'}; blah; CATCH{ when X::Foo { .resume } };
08:21 camelia rakudo-moar 16c5fc: OUTPUT«x␤y␤»
08:22 orbus is that by design?  that it should resume from *within* the function call it died inside?
08:22 orbus maybe I didn't read the docs close enough
08:23 orbus that seems both potentially useful and terribly dangerous
08:23 TimToady yes, and only that is why only resumable exceptions are, er, resumable
08:24 TimToady in general we call those "warnings" though
08:24 nine colomon: you still up?
08:24 TimToady it's usually a bad plan to try to resume an exception where the code throwing the exception isn't expecting to be resumed
08:24 orbus right
08:25 orbus well I'm just extending the base Exception class
08:25 orbus how would I specify I don't *want* my custom exception to be resumable?
08:25 orbus at least not inside my code
08:25 orbus if they want to pick up the pieces and continue after the catch block, that's fine
08:25 nine .tell colomon you're totally right, that .files call can never work. OTOH all you're missing out on is an error message, telling you that the script could not be found.
08:25 yoleaux nine: I'll pass your message to colomon.
08:26 TimToady I'm not sure how an exception gets a resume continuation in the first place, but presumably you could override the resume method to prevent it
08:27 TimToady but given it's after midnight here, I'm gonna hit the hay
08:27 orbus yeah, here too
08:28 orbus m: module Mine { my class X::Foo is Exception is export {sub resume {};} }; import Mine;  sub blah {say 'x'; die; say 'y'}; blah; CATCH{ when X::Foo { .resume } };

09:32 masak I once hit another limit where I had too many lexicals in a block.
09:32 masak yes, it was generated code.
09:34 RabidGravy I do wonder, considering that about 2/3 of all the m: things are to do with listy things, whether that part of the language is perhaps too rich ;-)

10:38 nine _nadim: yes. You can put your own CompUnit::Repository implementation into $*REPO and only forward allowed modules to $.next-repo.need

10:49 timotimo​mdk/status/681779386618654720  -  Hey Perl folks, is there new DevOps tools for Perl5? How does Perl6 work for SysAdmins?  FLOSSUK DevOps cfp 30/12/15
10:49 timotimo that's a really tight CFP deadline right there
10:50 ChoHag Wtf is a "DevOps tool"?
10:50 ChoHag A tool for performing development and maintaining operations? Like bash?
10:53 timotimo depends what level of sophistication and targetedness you set as a minimum for being called a tool
10:53 timotimo you could just as well say "what, you mean a computer?"
10:53 timotimo of course it refers to a computer and not a chair, or a plate, or a mug, or a spoon
10:53 stmuk devops just means "traditional UNIX sysadmin who programs a bit as well"
10:54 ChoHag Traditional unix sysadmins did program a bit though.
10:54 timotimo right, "infrastructure as code/declarations"
10:54 timotimo that's the "new" thing here
10:54 stmuk maybe what is less traditional might be the sysadmin talking to other people in the company and being friendly ;)
10:55 timotimo rather than having a bunch of one-off scripts, you'd have a framework that'd make re-use and scaling trivial or at least much simpler
10:55 ChoHag The good sysadmins, again, knew there were layers above 7 and how to utilise them.
10:55 ChoHag timotimo: That's a nice idea. I wonder when it'll happen.
10:55 timotimo :)
10:56 stmuk devop tool probably means something like puppet, cfengine etc
10:56 ChoHag Probably, sadly.
10:56 ChoHag I find them more of a hindrance myself, but the manglement folk like them.
10:57 stmuk if you are admining 1000s of systems you do need automation
10:57 timotimo well, bash scripts already let you do automation
10:57 virtualsue devops includes people like me, who wrote all sorts of infrastructure tools but never was a unix SA
10:57 stmuk until the guy who wrote the bash scripts leaves and noone else wants to touch them
10:58 ChoHag Puppet, cfengine, salt, chef and ansible are all different ways of ruining a good idea.
10:58 ChoHag Did I miss any? Is there Yet Another "let's do puppet *right* this time"?
10:58 stmuk I'd rather have an imperfect tool than none at all
10:59 RabidGravy I'm sure if you really tried the list would be inexhaustible ;-)

11:01 nine Ah
11:01 ChoHag How can I deal with a circular list of module dependencies other than by putting them all in the same file?
11:02 ChoHag eg. does perl 6 have _text_ level file inclusion?
11:02 nowan joined #perl6
11:02 ChoHag Or does creating empty classes in the big file and augmenting them with details in their own file still have problems I don't remember the details of?
11:04 nine ChoHag: why not just put them in a single file if they are that much interdependant?
11:04 ChoHag Because I'm getting tired of scrolling up and down so much and getting lost.
11:04 nine ChoHag: I use :vsplit for that in vim
11:05 ChoHag I use :vsplit for it in evil emacs, but it's still a PITA.
11:05 RabidGravy nine, yeah I came by the catch (releasing the implicit block was shagging up the import with try) before I went to the backlog :)
11:05 ChoHag Plus having separate classes in separate files is "Right".

12:35 nine Skarsnik: size_t's definition is actually rather close to Perl 5's IV. IV is defined as at least the size of a pointer while size_t has to have at least the size of a pointer to be usefull for object sizes (except on segmented architectures)
12:36 Skarsnik hm long is like int32 on my debian32 bits
12:36 Skarsnik it should work?
12:36 Skarsnik but I:p5 still fail
12:36 ShimmerFairy So in addition to still facing a show-stopping unknown bug introduced in the CURI branch way back, I can't even use Grammar::Tracer to diagnose the problem (in a multi token where it breaks, it seems, so it's hard to do without the tracer). Just wonderful.
12:36 leont Skarsnik: Got a paste of the fail?
12:37 lizmat leont: remembering from when I was working on the newio branch, it would need nqp support
12:37 Skarsnik leont, basicly it segfault and gdb is not useful. it's kinda of time out after leaving gdb

12:43 dalek joined #perl6
12:43 Skarsnik Grammar::Tracer?
12:43 timotimo lizmat: wow, 5x faster for .later? nice!
12:43 nine ShimmerFairy: or what is SUPERNOVA even?
12:44 ShimmerFairy nine:
12:45 ShimmerFairy nine: pretty much, I've never been too sure on the distinction between what 'use' uses for names and what it means to have 'unit module' or whatever inside the file; in this case, I've elected to fully qualify class names inside the files, instead of using unit module, back when I started work on it.
12:45 colomon nine: brilliant, that works!
12:45 ellybelly Hi all, I am thinking of writing a module, but someone else has written a similar one. How should I go about naming mine? For example, there is already WebService::Soundcloud, but I want to make a different Soundcloud module and submit it to the modules list.
12:45 timotimo ShimmerFairy: huh? but whether or not you use "unit" is only about the curly braces
12:46 llfourn ShimmerFairy: are you planning on making SUPERNOVA installable via panda?
12:46 ShimmerFairy timotimo: not 'unit' specifically, but the idea of wrapping the file's contents in a 'module'
12:46 timotimo oh
12:46 timotimo i see
12:47 nine ellybelly: have you considered cooperating with the author of the other Soundcloud module?
12:47 ShimmerFairy llfourn: not at the moment, the plan is for it to be assimilated into rakudo when it's time to do so (developing out-of-core is a lot faster than in-core) :)
12:47 nine *fetch stage failed for Grammar::Parsefail: Unable to handle source '​Fairy/grammar-parsefail/')
12:48 ShimmerFairy nine: yeah, that's something I've neglected to fix so far, in part because I swear it working before, and in part because dying on https:// seems silly. I'll go fix it now though.
12:48 llfourn ShimmerFairy: fair enough :)
12:48 ellybelly Thanks nine, I I wanted to do it in a different programming style, but also as a learning exercise.
12:49 |Tux| joined #perl6
12:49 nine ellybelly: trust me, you'll learn just as much by working on an existing code base :) And maybe the author of the other module actually likes your ideas for the interface and likes to adopt them?

12:51 ellybelly Thanks nine, that is good advice. For situations where someone is determined to create a similar module, what would be the standard convention?
12:53 Skarsnik is there a test to see if something warn in Test?
12:53 timotimo nothing pre-make, i think. but you can use CONTROL to catch warnings

12:58 nine ellybelly: otherwise, use the same name but make sure your :auth is different. But in any case _always_ try to talk with the other author. And if in doubt, ask here.

14:29 _nadim llfourn: Arff yes I see

14:30 FloydATC what about modules, won't p6 modules affect p5 ones?

14:30 llfourn FloydATC: not at all :)
14:30 llfourn FloydATC: rakudobrew will install a totally isolated environment
14:31 FloydATC so it's basically safe to do a root install of p6 and not have to worry about personal path settings etc?
14:31 llfourn FloydATC: do you need to install as root?
14:31 _nadim llfourn:  :name($a, $b), thought  $name($a, $b) is equivalent if $name ~~ 'name'
14:31 RabidGravy joined #perl6
14:32 llfourn FloydATC: just install under your user if you can
14:32 FloydATC Not sure but here's what I'm thinking; for years I've just put #!/usr/bin/perl in my scripts because perl is always there
14:32 _nadim FloydATC: you're the second person that asks that oday. I can't understand how pwople want to polute their evironment because they don't want to pollute their $PATH!
14:32 gfldex /usr/share/perl6/ <-- that's there perl6 goes
14:32 gfldex /usr/share/perl5/ <-- that's where perl5 goes
14:33 _nadim FloydATC: IMO, let RakudoBrew install where it wants and take the second to edit your .bashrc
14:33 llfourn FloydATC: there is 0 chance that anything bad can happen from using rakudobrew -- it will just get installed under $HOME/.rakudobrew
14:33 perlpilot FloydATC: I usually use  #!/usr/bin/env perl6  FWIW
14:34 perlpilot FloydATC: (once it's in my PATH like it should be :)
14:34 smls FloydATC: I use  #!/usr/bin/env perl  for Perl 5 scripts and  #!/usr/bin/env perl6  for PErl 6 scripts - this way it doesn't matter where they are installed, as long as $PATH is set up accordingly.
14:34 orbus .tell TimToady I did some more checking last night.  It's not documented in the class docs on, but the base Exception class does indeed have .resume .  If there's a way to prevent people calling it on custom exceptions in modules, I haven't figured it out yet.

14:35 perlpilot FloydATC: as long as your PATH is set appropriately.

14:36 orbus you just probably shouldn't unless you integrate it into your system's package manager :p

14:52 Skarsnik like it cleared /opt/bin and /opt/lib when given opt
14:53 ChoHag It shouldn't really remove anything at all.
14:53 llfourn ChoHag: hmm I would have thought that it would always be in .rakudobrew but I guess that got lost somehow :\
14:53 Skarsnik it removed what was not panda and some perl6 stuff
14:53 ChoHag Lift the old installation non-destructively into an out-of-the-way location and inform the user it's ready to be removed as desired.
14:54 Skarsnik ChoHag, I think the --prefix was for module prefix or something like that x)

14:59 Skarsnik Like: dies-ok{ sub test(Int $a) is native('fake') {*};} #this should die
15:00 llfourn Skarsnik: there's eval-dies-ok :)
15:00 Skarsnik Oh right I can use that
15:01 webstrand So I've managed to package panda using the command `RAKUDO_PREFIX="$pkgdir/usr/share/perl6/" ./` and patching to use --notests. Everything seems to work, is there anything I'm missing?
15:01 yoleaux 07:49Z <nine> webstrand: yes, RAKUDO_PREFIX was introduced after 2015.12
15:01 nine webstrand: \o/ if it work, it works :)
15:01 llfourn webstrand: sounds good to me

15:02 Skarsnik --notests sounds buggy x)
15:03 RabidGravy webstrand, may be worth pitching your results back to tadzik though
15:03 webstrand Unfortunately, with RAKUDO_PREFIX, panda dies because Tests is missing.

15:05 _wiz_ where's the best place to ask about Math::Pari build problems?
15:06 perlpilot _wiz_: probably #perl as I don't think there's a P6 version of Math::Pari yet.
15:07 RabidGravy that even used to be a bugger to build like twenty years ago
15:08 Skarsnik Test summary should display the test that failed...
15:08 perlpilot _wiz_: If you're really trying to get at PGP::Crypt though, look for an RPM or DEB or whatever for that as there's usually one out there without Math::Pari
15:08 zemmihates joined #perl6
15:08 autarch [Coke]: I profiled Pod::TreeWalker t/basic.t - it allocated 13k scalars, mostly in core code - so whatever that code does is at least part of the problem
15:08 RabidGravy wasn't it by that crazy clever russian maths guy
15:09 autarch I mean that TreeWalker is doing something to cause bad behavior, not just Pod::To::HTML
15:09 webstrand flussence: I'm not really sure how perl6 uses vendor or site. But though it claims the directory /waur/perl6-panda/pkg/panda/usr/share/perl6/vendor is in the search path, it still can't find Test.
15:09 Skarsnik damn, no NC developper around?
15:10 webstrand Well, I cant find a Test~ anything either, so I'm not sure what perl is looking for.
15:11 flussence it's looking for, which would've been mangled into one of the sha1 filenames in /usr/share/perl6/
15:12 _wiz_ perlpilot: thanks, I'll try that.
15:12 RabidGravy is there an %INC equivalent? we can test this for avoidance of doubt
15:12 Su-Shee can I use rakudobrew without appending it to my bashrc? I just want to toy around with the recent perl6.
15:12 nine webstrand: Test is part of the CORE dist in the /usr/share/perl6 repository
15:12 Skarsnik Su-Shee, yes
15:13 Su-Shee (btw - ALL install guides point to different perl 6 versions, really annoying. you can't copy paste any of them)
15:13 Skarsnik you can manually call rakudobrew
15:13 Su-Shee Skarsnik: ok.
15:13 Skarsnik it's just rakudobrew will put perl6 bin and co in its directory

15:15 Skarsnik Oh there is already a check for the content of CARRAy, fun
15:15 asht I just built rakudo star on ubuntu and all went well. tested a few simple scripts. How does one actually "compile" and build executable ?
15:16 nine webstrand: maybe setting PERL6LIB='inst#/usr/share/perl6' works, too? Would be a much nicer solution.
15:16 awwaiid Reading S12 a bit, I see that you can do "has $x" instead of "has $!x" and it works the same. I guess the reason I see the ! so much is it being more obviouse that it is an instance var?
15:16 webstrand nine: Is there any documentation on how perl6 searches for modules? You mentioned name mangling
15:16 nine webstrand: or RAKUDOLIB instead of PERL6LIB, als panda's may overwrite PERL6LIB

15:23 RabidGravy needs to be disambiguated from buiild $something

15:27 mst Su-Shee: 'build foo' is 'build rakudo with backend foo'
15:27 yoleaux 09:08Z <nine> mst: I think we're gonna have to be smarter about identifying usable precomp files anyway. Right now, we have to precomp all modules again after installing any module. And precomp files created by panda are invalidated as soon as you install a vendor module package
15:28 FloydATC Su-Shee: I found both panda and perl6 in .rakudobrew/bin/
15:28 mst nine, yeah, I already proposed a solution for that - basically re-dry-run just the resolutions
15:28 RabidGravy muraiki, that's the wrong way round the '.' twigil gives it an accessor, thus making it "public"

15:38 Su-Shee mst: that's the line which adds to the bashrc, not the line which just adds to the path. you'd have to say for new people which one to use preferably. also, see above, I asked beforehand if rakudobrew works without adding it permanently to the bashrc. it's very confusing if you don't know perlbrew already.

15:40 mst yes it is
15:40 Ulti because reasons
15:40 masak gnnnrk
15:40 llfourn yup
15:40 mst because 'rakudobrew build' should've been called 'rakudobrew build-rakudo'
15:40 llfourn it used to be build panada though I think
15:40 geekosaur arguably should be build-perl6
15:40 RabidGravy Ulti it was I just can't remember who
15:40 Ulti probably not great reasons
15:40 * masak wants to afflict someone with severe consistency
15:40 geekosaur or that

15:41 yoleaux 28 Dec 2015 23:29Z <AlexDaniel> tadzik: yeah, great! Travis status is a bit weird, why does it attempt to run it on 2015.09? Anyway, that means that could be closed after the tests are added
15:41 skyl4rk joined #perl6
15:41 Ulti tadzik heh
15:41 Ulti we cant break back compat!
15:41 tadzik it's already called rakudobrew, so 'build-rakudo' is quite redundant
15:41 Ulti ever
15:41 Su-Shee masak: well. I asked that 10 minutes ago.
15:41 tadzik build-panda was an addition, and it also works as 'build panda' since everyone accidentally writes it that way
15:42 mst yes, but apparently he wasn't reading, so I answered it again
15:42 masak Su-Shee: sorry, my backlogging sucks these days :/
15:42 mst all good
15:42 Su-Shee tadzik: then why not just write build panda everywhere? because I typed build panda as well and it just worked :(
15:42 masak <Su-Shee> perlpilot: why is it build moar but build-panda?
15:42 tadzik I don't mind removing the build-panda form
15:42 masak found it :)
15:42 tadzik also
15:42 tadzik well
15:43 masak tadzik: I'm fine as long as it works both with and without the hyphen ;)
15:43 llfourn should be fine unless someone invents a pandaVM that runs rakudo
15:43 masak tadzik: that, or only one of the ways works.
15:43 tadzik I caught myself trying to explain it like "it's obvious if you look at how it's implemented!" but that's just a stupid excuse :)
15:43 webstrand joined #perl6
15:43 Ulti just 'build' defaulting to the current tagged release and building panda too would be good
15:43 masak tadzik: :D
15:43 tadzik masak: so you're fine either way?
15:43 masak tadzik: no, no
15:43 tadzik oh
15:43 tadzik well, both forms work now
15:43 tadzik so you're happy :)
15:43 masak tadzik: should be "all four forms work now" for me to be happy
15:44 tadzik oh
15:44 perlpilot tadzik: I want "rakudobrew dwim" to do all the things in just the right way that makes me happy  ;-)
15:44 Ulti surely the panda vm would be called bamboo
15:44 Su-Shee well it looks like a typo when you actually read the docs. so you start question of it.
15:44 tadzik perlpilot: that's actually brilliant
15:44 tadzik Ulti: bamboo already exists :)
15:44 Ulti because pandas run on bamboo
15:44 masak tadzik: `build-moar`, `build moar`, `build-panda`, `build panda`
15:44 mst perlpilot: yes, I've already been thinking about that
15:44 Ulti oh well we can target it then :D
15:44 tadzik it's a dependency bundler:

15:44 mst that's a better name than I had for it
15:44 masak RabidGravy: right
15:44 masak RabidGravy: I think space is less confuzzling than hyphen
15:44 tadzik so, tl;dr: change the documentation to remove the hyphen
15:44 masak aye

15:55 RabidGravy better share the code then as I'm on Fc22 too

15:57 RabidGravy I think "parse" "ast" and some other things are valid targests but only useful for deep debugging
15:57 FloydATC Even more confused now. I installed "HTTP::Server" using panda but can't find it anywhere. My test script is okay with "use HTTP::Server" but p6doc says it can't find "HTTP::Server".

16:02 llfourn FloydATC: I'm not sure that p6doc works with modules...
16:02 RabidGravy FloydATC, I don't think p6doc has caught up with the way the modules are stored
16:02 * llfourn has never used p6doc
16:03 FloydATC ok, makes sense
16:03 Ulti asht: you can also --target=parse and --target=ast which are some of the compiler steps before producing anything executable, only really useful for slang/compiler debugging
16:03 FloydATC So, how are the modules stored? Because I've tried locating them and can't
16:04 llfourn FloydATC: somewhere in .rakudobrew if you're using it
16:04 FloydATC I am, but 'find' comes up with nothing that matches so I'm a little confused
16:05 Ulti try grep for the class name
16:05 FloydATC In fact..  s/a little//;

16:07 ShimmerFairy try ~/.perl6
16:08 llfourn hmm so like FloydATC is right i can't find em either as .pm files
16:08 perlpilot yeah, but good luck finding something resembling the name ""
16:08 llfourn I can find precomp files
16:08 FloydATC Nothing in ~ at all, in fact I changed to root, did 'updatedb' and then locate, still only finding perl5 stuff
16:08 llfourn so panada doesn't keep the .om around anymore?
16:08 llfourn s/om/pm/
16:09 awwaiid perlpilot: it's rakudobew build-panda last I knew
16:09 RabidGravy it hashes the .pm file too
16:09 llfourn ahh that makes sense
16:09 perlpilot awwaiid: aye, but "rakudobrew build panda" also works and seems to be less confusing
16:09 llfourn I mean that explains what I'm seeing not that I understand why
16:10 RabidGravy so "find <wherever> | xargs grep -l HTTP::Server" should find it
16:11 zakharyas joined #perl6
16:11 llfourn hmm so #inst compunit repo stores files as hashes
16:11 Skarsnik hm, How I get the 'value' of a Parameter?
16:11 RubiO masak, RabidGravy, I reduced the problem to this: I can have non-ascii chars on token names on a grammar, but I got that error if I try to refer to the declared token using <>.
16:12 RubiO For instance, this passes OK on "perl6 -c": grammar { token TOP { <numero>+ } token número {<< \d+ >>} }
16:12 RubiO But this does not: grammar { token TOP { <número>+ } token número {<< \d+ >>} }
16:12 Ulti Skarsnik a command line one? @*ARGS
16:13 Skarsnik nop the Parameter type
16:13 Skarsnik
16:13 Skarsnik but come to thing of it, it's probably not "doable"
16:13 Ulti do you mean specifically from within a function getting the params of that function
16:14 RabidGravy RubiO, I was going to ask you to distl it down but you did,  unless someone chimes in I'd suggest that may be worth an RT
16:14 RabidGravy m: grammar { token TOP { <número>+ } token número {<< \d+ >>}
16:14 camelia rakudo-moar 74ab05: OUTPUT«===SORRY!===␤Error encoding ASCII string: could not encode codepoint 250␤»
16:14 perlpilot RubiO: also, you said you don't get that error on JVM?
16:14 chansen_ lizmat: If you really want to make DateTime faster, only store absolute count of elapsed unit since epoch and lazily compute the broken down components. Current implementation makes the same mistakes as the Perl5 implementation of
16:14 RubiO Here's a better example. This runs OK: perl6 -c -e 'grammar { token TOP { <numero>+ }; token número {<< \d+ >>} }'
16:15 RubiO This does not: perl6 -c -e 'grammar { token TOP { <número>+ }; token número {<< \d+ >>} }'
16:15 RabidGravy I'm curious now
16:16 RubiO perlpilot, yes. This runs OK: perl6-j -c -e 'grammar { token TOP { <número>+ }; token número {<< \d+ >>} }'
16:16 RabidGravy m: sub número() { say "ahay" }; número()
16:16 camelia rakudo-moar 74ab05: OUTPUT«ahay␤»
16:16 lizmat chansen_: is there a Perl5 implementation without those mistakes ?
16:16 RabidGravy okay, so it's "just" in there
16:17 RubiO Strangely enough, yes.
16:17 Skarsnik Ulti, I am validating the signature of a routine and I want to valid too the evenvual parameters of a callable if one is given
16:17 RubiO And I'm sure it ran before. It must have been introduced in some recent update
16:18 chansen_ lizmat: Time::Moment, but most of it's implementation is in C/XS
16:18 perlpilot that would normally make me think that it's really an NQP problem leaking through, but I'm not so sure

16:27 masak tadzik: you can always claim it's short for "install all" :P
16:27 perlpilot "rakudobrew install all the things now please"
16:27 RabidGravy but top bug, nonetheless.  It's a worry when actual real bugs are more exciting than misunderstandings
16:28 pmurias RabidGravy: --target=ast is awesome for the implementers
16:28 pmurias AFAIR niecza didn't have proper ast dumping support and it was a major barrier for getting involved with it's development

16:45 hankache anyone working on the windows MSI?
16:45 chansen_ lizmat: IMHO, core DateTime should be fast and correct
16:45 lizmat chansen_: dates and times are two different things
16:46 lizmat chansen_: agree with you on the correct part: and afaik, it's now correct except for "now" being one second off when inside a leap second
16:46 lizmat but that is an underlying OS issue, really, I'm afraid
16:47 lizmat chansen_: at former $work, I used to have to deal with dates a lot
16:47 lizmat if you know the range in which you want to accept dates, things can be speeded up by again some order of magnitude
16:48 lizmat but DateTime/Date/Dateish need to be more general, so no go for that  :-)

16:51 ShimmerFairy .tell nine according to bisection, ac7b2a5a8381d5f255906437d1980c9c3b77e2a5 is the rakudo commit that breaks SUPERNOVA for me (without trying Grammar::Tracer). And I can't tell why.
16:51 yoleaux ShimmerFairy: I'll pass your message to nine.
16:51 chansen_ lizmat: I'm not talking about leap-seconds, in p5 and p6 pretends to observe leap-seconds and is probably the only one that does in a "standard" library which is just silly IMHO!
16:52 perlpilot pmurias: nice
16:52 chansen_ lizmat: You cannot obtain current time from OS using time() or gettimeofday() and observe leapseconds
16:52 pdcawley joined #perl6

16:53 chansen_ You need to query NTP to obtain whether or not leap second is in effect

16:54 RabidGravy pmurias, as some of my DJ friends say "full support" :)
16:55 ChoHag There's nothing silly about being correct.
16:56 ChoHag If leap seconds exist, software which deals with times should consider them.
16:56 chansen_ lizmat: Learn from others, don't learn from p5 DateTime!
16:56 simcop2387 joined #perl6
16:57 cosimo timotimo: ok
16:57 lizmat chansen_: well, I'm afraid your suggestion comes quite a few years too late  :-(
16:57 lizmat chansen_: but as always, patches welcome
16:57 perlpilot chansen_: you could offer a "better" implementation.  If it's truly better, it could find its way into core.
16:57 RabidGravy I'm torn.  Only a canonical time source can no about leap seconds
16:58 RabidGravy know even
16:58 ChoHag I know about leap seconds, and there's nothing canonical about me.
16:58 lizmat chansen_: personally, I'm just about done with Dateish/Date/DateTime
16:58 autarch FWIW, I agree with chansen_ about leap seconds - totally not worth it
16:58 perlpilot RabidGravy: a priori, yes, but after the fact, anything can "know" about leap seconds.  :)
16:58 RabidGravy ChoHag, but you're special :)
16:59 japhb Also, how leap seconds are handled isn't standardized even by those who care.  Several cloud providers "smear" leap seconds, for example.
16:59 perlpilot autarch: do you also agree with his assessment of DateTime?  :)
16:59 lizmat well, everybody: leap second support is engrained in 6.c now, so not going to go away
16:59 chansen_ perlpilot: which assessment?
16:59 autarch perlpilot: somewhat - there are things that DateTime does really well
16:59 ChoHag Since perl 6 isn't an OS or even its kernel, leap seconds only need to be counted, not lived.
16:59 lizmat you don;'t want to know how many tests we have for that  :-)
17:00 perlpilot chansen_: the "mistakes" you mentioned.
17:00 pierre-vigier joined #perl6
17:00 autarch I do want to see p6 have full support for time zones as Olson zones with rules, not as offsets
17:00 japhb Ditto that ....
17:00 ChoHag What you don't want is some developer deciding that they absolutely must handle leap seconds, finding out that DateTime doesn't, and rolling their own.
17:00 autarch I will say that supporting time zones _and_ leap seconds makes life incredibly hard
17:01 autarch and of the two, tz support is far more practically useful
17:01 japhb autarch: Why so?
17:01 ChoHag Well perl's all about making the impossible merely hard.
17:01 japhb Are there any leap seconds near rule boundaries?
17:01 autarch japhb: when constructing an object from the local time, it's really hard to figure out if it's valid
17:02 japhb Oh, hmm.
17:02 chansen_ perlpilot: As I said, look at GO, C#, C++ boost, ObjC NSDate, If you want papers (I have booksmarks, let me know=
17:02 chansen_ .. GDateTime
17:02 autarch to clarify - if you specify "second = 60" then validating that requires you to know the offset from UTC, which is tricky to figure out before validating the values
17:02 TimToady translate to atomic and back, and see if it matches?
17:03 dalek rakudo/nom: 461e635 | lizmat++ | src/core/Date (3 files):

17:03 dalek rakudo/nom: Date/DateTime
17:03 dalek rakudo/nom: review:
17:03 perlpilot or ... forego validation  ;>
17:03 autarch if I were to do it all over again I'd probably look for a C library that does most of this and link against that or something
17:03 japhb autarch: Ah, I can see the chicken-and-egg problem, yes.
17:03 chansen_ perlpilot: I did my research when I implemented Time::Moment in C/XS
17:04 lizmat autarch: well, the Date/DateTime modules predate NativeCall... they were one of the first to be implemented, I think
17:04 autarch​i-review-datetime-and-datetimeduration/ - my review of DateTime
17:04 * leont agrees with Olson zones being way more useful than offsets
17:04 japhb chansen_: Note that "no one else in the language dev community decided to try" is not in itself an argument that necessarily sways the Perl community ....
17:04 TimToady yeah, we're funny that way
17:04 ChoHag Actually doing shit?
17:04 ChoHag Who *does* that?
17:05 leont In fact, I'd say offsets are so often used wrong that they can be harmful
17:05 RabidGravy ornery mofos thelot of 'em
17:05 TimToady now, let's keep it butterfly friendly, kids
17:05 autarch yeah, offsets are basically just wrong
17:06 RabidGravy TimToady, I was ;-)
17:06 chansen_ japhb: I'm not sure I follow, care to elaborate?
17:06 autarch offsets fall under "making hard things harder, and wrong things easy"
17:06 ChoHag Do butterflies not swear?
17:06 chansen_ autarch: I agree
17:06 ChoHag autarch: That's basically programmin in a nutshell.
17:06 cdg joined #perl6
17:07 chansen_ autarch: But Time::Moment is a true implementation of ISO 8601
17:07 TimToady not when there might be larvae reading the logs
17:07 RabidGravy a kind of rooting question, how often are leap seconds issued?
17:07 perlpilot whenever needed
17:07 perlpilot but no more than 2 times per year
17:07 leont Once every ±3 years on average, I think
17:07 ChoHag Languages should stop people doing stupid things when hammers can no longer hurt thumbs.
17:07 TimToady it depends on how hard the asteroid hits and at what angle
17:07 RabidGravy right
17:08 chansen_ heh
17:08 TimToady speaking of hammers
17:08 japhb chansen_: Meaning: we might get things wrong (and we have), but lots of other languages not doing something never stopped us from *trying* to get something right before.  :-)
17:08 autarch the rest of the core p6 DateTime stuff looks fine, but I think it'd be good to rip out the timezone bits and replace them with something Olson-ish
17:08 Skarsnik "Let's add this to NC, it should only take an hour"... 4 hours later
17:09 japhb autarch: Sadly, we need both, in order to interop with the ISO standard.
17:09 autarch I wish there were an Olson C lib
17:09 japhb ... but I will heavily second *that*
17:09 ChoHag 400%? I'm still in the foundation stages 3 years later on something I was sure would take about 4 months. 6 tops.
17:09 autarch japhb: given the _current offset_ in seconds or formatting as "+07:00" is totally ok - calling that a _time zone_ is not
17:09 TimToady quick, write a C backend for Perl 6, and we can write the C lib for them
17:09 RabidGravy a lot of worry and sweat over a ~ 1/100000000 inaccuracy this then
17:09 autarch TimToady: back in 5 minutes
17:09 japhb autarch: Ah, then we 100% agree
17:10 autarch done - finished early
17:10 chansen_ I definitely agree with autarch, I have received countless of emails asking how to use Time::Moment with time zones.
17:10 TimToady :D
17:10 autarch it's at
17:10 perlpilot RabidGravy: well ... we want P6 to be used for highly accurate things at some point  :)
17:10 TimToady actually, you just have to unroll MoarVM, since it's in C
17:11 autarch in all seriousness, parsing the Olson files in Perl 6 should not be too hard other than the fact that there's basically zero documentation of the internal format other than some of the grottiest C code I've ever looked at ;)
17:11 pierre-vigier joined #perl6
17:11 ChoHag Perl programmers are no strangers to grotty-looking source code.
17:11 TimToady we speak Unicode, so how hard could Olson be?
17:11 japhb autarch: I would think your Perl 5 code qualifies in that regard as well ....
17:11 ChoHag TimToady: Thems sounds like famous last words.
17:12 RabidGravy I like second accuracy, I run a radio station that annoys the DJs by starting and ending their shows bang on the second they're supposed to, but what?
17:12 autarch japhb: I don't parse the binary files - just the text source - but that was a terrible idea
17:12 chansen_ autarch: how about two implementations, one that uses the tzfile(5) provided by many OS and one that uses Olsen raw data?
17:12 autarch _do not do what I did_
17:12 hoelzro pmurias: looks good to me!
17:12 autarch chansen_: I think it might be easier to just package up the Olson binary data as a Perl 6 distro for OS's that don't include it

17:14 japhb autarch: Psssh, I've seen *way* grottier C code.  :-)
17:15 autarch japhb: great, explain to me what the heck that does then!
17:15 japhb Though the formatting rules are ... weird.
17:15 flussence so if anyone's thinking of writing a zonefile parser, test it against that reference implementation :)
17:15 chansen_ autarch: That would also work
17:15 japhb autarch: I just remembered, I have something else to do ...
17:15 autarch flussence: yes, that's how I generate test for DateTime::TimeZone
17:15 * japhb hums innocently
17:16 lizmat autarch: for adding Olson timezone support, you only need to augment method new() with a candidate that takes Str:D $timezone instead of Int

17:16 pierre-vigier joined #perl6
17:16 leont Who the hell assumes the compiler has 5 registers available?
17:16 autarch lizmat: well, then the internals need to do something with that, and the timezone method should not return what it returns now
17:16 leont That's just, dumb
17:17 RabidGravy I think I'm going to have to "upgrade" to some serious beer to follow this
17:17 lizmat autarch: call BUILD the same was as the current main new, and we should be in business
17:17 chansen_ leont: 5 registers, which compiler?
17:17 leont No, 8 even!
17:17 leont That code autarch just linked
17:17 RabidGravy leont, I'm sure there are microcontrollers that do
17:18 leont I'm sure there are, it's just but this isn't code for microcontrollers
17:18 japhb I like the bit where the comments go into great detail about the age of the big bang ... and then round to the nearest power of two.
17:18 autarch lizmat: it's a little more involved than that - you can't just turn an Olson tz into a number and then use that internally
17:18 leont (grammar!, sigh)
17:18 timotimo oh hey japhb
17:19 japhb oh hey timotimo
17:19 lizmat autarch: you can for a given YYYMMDDHHMMSS ?
17:19 ChoHag How do we specify and use class/module versions?
17:19 timotimo i feel i'm a bit reluctant to go ahead and run benchmarks with current rakudo and older rakudos because of the "tests require different code at different releases" :|
17:19 timotimo oh, and i still ought to write that weekly
17:19 autarch lizmat: yes, but things like .later and .earlier need to pass the zone name around so that you get the right local time
17:19 RabidGravy speaking of which I'm going to completely rip off the C code from Device::SMBus in a minute
17:19 timotimo i could get started on that after grocery shopping
17:19 ChoHag I recall a lot of arguments on this in perl 5. Did 6 solve the problem or do we now have n+1 standards?
17:19 autarch also, how do you handle non-existent local times, 25 hour days where there are two of the same hour, etc.
17:19 RabidGravy get beer it will help
17:20 leont Time is difficult :-(
17:20 japhb timotimo: We should fix (if needed) any tests for Perl 6 6.c and NQP 2015.12, and anything too old for that is ... too old.
17:20 nine ChoHag: we do have a Version class and version literals.

17:20 japhb I find myself less interested in the deep past recently.

17:22 RabidGravy leont, leave peoples gyrations outta this
17:22 * leont throws relativity at perlpilot
17:22 japhb perlpilot: Do you consider "general relativity" one of those human gyrations?
17:22 ChoHag Should DateTime handle time dilation?
17:22 * perlpilot catches the relativity and juggles it with classical mechanics
17:23 RabidGravy it would be so much simpler if everything happened all at once
17:23 timotimo japhb: if anything past 2015.12 is "too old", i can hardly get a good performance comparison against older versions :)
17:23 * flussence goes to check up on What Would Postgres Do?™ in this situation
17:23 ChoHag RabidGravy: It does.
17:23 japhb timotimo: Well, you can, just not a *complete* one.  Older compilers will handle fewer and fewer of the tests.
17:23 ChoHag With the right definition of "once".
17:24 timotimo fair enough
17:24 TimToady Perl 6 is designed to track atomic time.  It doesn't really care *whose* atomic time it's tracking. :)
17:24 timotimo i suppose i'll just go do a run or two
17:24 RabidGravy that's alright then. time is hitler
17:24 TimToady we're done here :)
17:24 japhb timotimo: You just won't be able to use the single summary number for overall performance comparison, unless we change the way it is calculated when tests are missing.
17:24 FloydATC I thought time was money
17:24 chansen_ lizmat: there are two sides, the instant and the local date. When computing the offset from a local date there is potential result of ambiguous/non-existant time while computing the offset from instant is unambiguous.
17:24 ChoHag Did a discussion on time just get Godwinned?
17:25 ChoHag Impressive.
17:25 perlpilot "Every Perl 6 compiler ships with a Cesium 133 atom to calibrate it's DateTime implementation"
17:25 ChoHag Must have been going on for a ... long time then.
17:25 perlpilot s/it's/its/
17:25 RabidGravy :)
17:25 flussence hm, pg's built in idea of a "time zone" is 4 digits too...
17:25 timotimo perlpilot: isn't a single atom a bit too sparse to get atomic time pings?
17:26 RabidGravy perlpilot, the export regs might be trickt but hey. I've been pestered by boeings lawyers for less.
17:26 japhb ChoHag: I suddenly have the urge to find some tie-in that would make the Godwin application actually relevant.
17:26 ChoHag timotimo: The idea is to get the cumulative effects of all the perl 6 users.
17:26 perlpilot ChoHag: that's also how we track them  ;)

17:28 autarch lizmat: that might work, but I'd have to think about it
17:28 japhb mst: "It's called that, because there's so much of it."
17:28 perlpilot japhb: "Perl 6 was so revolutionary, we had to kick some people off the planet" ?
17:28 japhb perlpilot: :-D
17:29 autarch lizmat: there are a lot of gotchas once you start handling time zones properly
17:29 lizmat well, I'm done with Dateish/Date/DateTime now
17:29 ChoHag Isn't time/date handling more gotcha than not?
17:29 lizmat scratched my itch
17:29 japhb mst: That, BTW, was pretty much the defining line in one of my all time favorite movie reviews, ranting about spaceships constantly colliding with each other.
17:29 autarch the other alternative is to have the core class not do anything with time zones at all, just treat everything as a floating time and leave this up to someone else to implement in the future
17:30 perlpilot lizmat++
17:30 mst japhb: hah, yeah
17:30 autarch ChoHag: pretty much
17:30 perlpilot lizmat: it's good to move on before getting sucked into the mire.
17:30 ChoHag autarch: The problem with that is, they will.
17:30 mst novels where that obviously can't even happen are nice

17:32 RubiO joined #perl6
17:33 perlpilot autarch: that's something I was going to suggest 30 minutes ago, but then I thought about the fallout from people trying to use DateTime without realizing that timezones are separate.
17:33 RabidGravy autarch, you old stick in the mud ;-)
17:33 autarch perlpilot: again, as it stands now it's mostly going to encourage very broken code around anything tz-related, so having _no_ support might be better in the short term
17:33 ChoHag I know, but there's a difference between what's meant and what happens, and some unfortunate sucker has to deal with the latter.
17:34 lnrdo joined #perl6
17:34 * leont agrees with autarch
17:34 flussence postgres' timezone handling seems less than useful: it accepts named zones for input, converts everything to utc, and drops the tz in storage
17:34 TimToady joined #perl6
17:34 autarch one of the things I realized after many years of working on DateTime was that having separate Date, DateTime (sans TZ) and DateTime::WithTZ classes would probably have been a better design
17:34 autarch there's a _huge_ amount of stuff that people want to do that does not require TZ support at all
17:35 perlpilot autarch: if only that unevenly distributed future could be concentrated a little bit for date/time handling ...
17:35 flussence autarch: well, that's what pg's docs say it does, but see above :)
17:35 autarch yeah, Pg's support is really lame
17:36 autarch if you need _real_ TZ handling you have to store a UTC timestamp and a separate zone name
17:36 flussence it is, but at the same time it's the best I've seen in any db :(
17:36 lizmat autarch: yes, a completely separate date handler would be handy
17:36 autarch lizmat: well, that already exists, right?
17:36 lizmat but I guess that'll have to live in module space
17:37 lizmat you mean Date?
17:37 autarch yes
17:37 RabidGravy which is a good thing
17:37 lizmat well, I don''t think using year/month/day internally for a date, is a good thing
17:38 lizmat you probably only want to use a day value (e.g. since epoch) internally
17:38 autarch I'd recommend Rata Die, actually
17:38 lizmat and only make the y/m/d happen when needed
17:38 autarch but that's really an implementation detail
17:40 lizmat intriguing
17:40 autarch I mean, as far as internals, it's almost certainly better to use "days since X + seconds since start of day" - but what really matters right now is the public API
17:40 lizmat but in my experience, at $work, one only needs to support dates of a certain range
17:40 autarch someone could rewrite the internals of the existing classes very easily
17:40 autarch lizmat: Rata Die makes it easy to convert to other calendars too
17:41 chansen_ We need Date (without time in zone of interest, not anchored on the global timeline), DateTime (date with time in zone of interest, not anchored on the global timeline), DateTime (with zone, anchored in the global timeline), DateTime (with offset, anchored on the global timeline).
17:41 autarch chansen_: I think the last two are the same thing - you can have a zone that has a fixed offset for all UTC times
17:42 RabidGravy I think that can happen in module space fpr people who need it
17:42 dalek roast: 4f2efb6 | lizmat++ | S32-temporal/Date.t:
17:42 dalek roast: Add basic tests
17:42 dalek roast: review:
17:42 chansen_ autarch: questionable, they can be comparable but not more
17:42 autarch I mean that they could use essentially the same implementation internally
17:42 * lizmat is looking forward to a module space implementation
17:42 chansen_ autarch: sure
17:43 RabidGravy I'm with lizmat
17:43 autarch well, none of that addresses the issue with what's in core right now
17:43 autarch I really do think it's likely to cause problems
17:43 lizmat autarch: specifically because ?
17:43 autarch and it's not an API that an external module that did Olson time zones could match all that easily
17:44 autarch lizmat: because people will try to use it to deal with time zones and it won't quite do things right but they won't know that
17:44 RabidGravy isn't that solved by documentation?
17:44 autarch they'll do something like ..., :timezone( determine-local-offset() ).later( :6months ) and that _will_ give a wrong answer in many many places
17:44 chansen_ It's simple, we could do this the right way (which would solve all temporal issues) or we could leave it as is, which just would confuse developers/users
17:45 leont Yeah, what autarch says
17:45 autarch RabidGravy: what would the docs say? "this sort of works, as long as you don't use certain features together, so be careful"
17:45 chansen_ autarch++
17:45 leont Reminds me of a forum I frequent, where I have to set my time-offset twice per year, because it doesn't handle DST
17:45 autarch here's another alternative - we create a global lobbying group aimed at abolishing DST worldwide - problem solved
17:46 chansen_ hehe
17:46 autarch at least for future times
17:46 chansen_ autarch: It's clear that we have spent to many hours with temporal data ;o)
17:46 RabidGravy they can't even manage it for Scotland, I think that plan is stuffed
17:47 autarch yeah, it's the worst
17:47 stmuk_ and everyone use Greenwich time :P

17:48 mst swatch beat time!
17:49 stmuk_
17:49 lizmat autarch: with minor adjustment, it should handle Olson timezones correctly if such a candidate would come to exist
17:49 RabidGravy I've actually got a bottle of Meantime London Porter in the kitchen
17:49 lizmat autarch: specifically, it should need to call .new, instead of the nqp::create.BUILD shortcut
17:49 autarch lizmat: sort of - I think you'd need to really start treating the timezone as an object, not as a number
17:50 pierre-vigier joined #perl6

19:07 smls Is there some magic uppercase method that a class can implemenbt to participate in .sort?
19:08 araujo nine, ok, let's see
19:08 ZoffixW What you guys think of this?
19:09 ZoffixW jberger linked me to it asking what release post they should link to... and reading the post, they seem to be incredibly confused about what Perl 6 is and the "final" "official" "release of Perl 6"
19:10 perlpilot ZoffixW: aye, confused.
19:10 nine m: class A { has $.a };  multi sub infix:<cmp>(A $a, A $b) { $a.a <=> $b.a };  my @a =>42),>5);  say @a.sort

19:11 ZoffixW perlpilot, BTW you have a PR to fix indexing issue of your module:
19:11 flussence ZoffixW: I don't think we should bother trying to correct every misinformed word-count-driven blog out there :)
19:11 ZoffixW flussence, I'm with you on that :P
19:12 V_S_C joined #perl6
19:12 mojca joined #perl6
19:12 hankache joined #perl6
19:12 flussence if they can't even be bothered spending 3 minutes to ask if what they're writing is correct... why should we?
19:12 ZoffixW Almost sounds like a crawler robot wrote it by scrounging various news websites.
19:12 mojca does moarvm with jit work on 32-bit platforms at all?
19:12 perlpilot oops ... thanks
19:13 perlpilot Perl has made me lazy with trailing commas
19:13 ZoffixW :)
19:13 hankache what is CURLI?
19:13 FloydATC This is the blogosphere, where the primary income is from rabid commenters pointing out their mistakes
19:13 mojca on i386 one gets src/jit/emit_x64.dasc:266:86: warning: shift count >= width of type
19:13 perlpilot hankache: Comp::Unit::Repo::Local::Installation I think
19:13 nine mojca: no jit on 32 bit
19:14 ZoffixW Oh really?
19:14 mojca shouldn't this be disabled automatically then?
19:14 ZoffixW Does it mean my perl6 will be even faster on a 64-bit box?
19:14 flussence mojca: it is...
19:14 mojca See
19:14 FloydATC *scratches head* how do I get the peer address for an IO::Socket::INET now?
19:15 mojca for some reason it ended up being compiled on user's machine
19:15 hankache perlpilot thanks, I just read it in a blog post, was just wandering what it is
19:15 hankache wondering**
19:15 awwaiid TimToady: I think that Ruby is the next-most-sisterly language, and I'm hoping to illustrate that the tone of the document isn't quite right for coexistence. I'll submit a patch to the 5to6 doc (even the name of the doc implies upgrading) to smooth it out a bit more.
19:15 V_S_C I just tried building rakudo from source
19:15 nine hankache: CURLI was CompUnitRepo::Local::Installation, curli was the name of a branch in which we completely refactored the whole module management part. The successor of CURLI is CompUnit::Repository::Installation
19:15 flussence mojca: possibly nobody's tested it on amd64+OSX before
19:15 asie joined #perl6

19:16 leont Sounds unlikely
19:16 nine lizmat++ is using OS X on a 64 bit machine
19:16 mojca flussence: how do you mean amd64+OS X? I'm not sure what processor the user has though, but it could be 32-bit
19:17 V_S_C and perl fails with unknown OS 'msys'
19:17 V_S_C *Configure
19:17 ZoffixW V_S_C, what OS are you on?
19:17 leont msys is what git on windows uses
19:18 V_S_C Windows x64
19:18 perlpilot awwaiid: agreed about Ruby  (maybe kind of a cousin than sister though)
19:18 V_S_C perl is available as I have git installed
19:18 mojca what's the role of D_DARWIN_USE_64_BIT_INODE=1 ?
19:18 leont It's mingw related, but I forgot the details
19:19 hankache nine perlpilot i am trying to understand what this blogpost is about​/the-supernova-has-been-delayed-such-a-shame/
19:19 mojca libuv unconditionally sets "if DARWIN libuv_la_CFLAGS += -D_DARWIN_USE_64_BIT_INODE=1"
19:19 ZoffixW mojca, does seem like it's a 32-bit box. In the moarvm build log I see: DEBUG: OS darwin/10.8.0 (Mac OS X 10.6) arch i386
19:19 flussence iirc building on windows has to be either completely native, or completely cygwin
19:21 mst you can't build it on cygwin at all, libuv fills its diaper far too early on
19:21 V_S_C I am using the VS2015 x64 native tools command prompt
19:21 perlpilot hankache: maybe ask ShimmerFairy.  She's "here".
19:22 * flussence retracts answer in favour of mst's, I'm only repeating what I've absorbed from hours of staring at makefiles and configure scripts lately :)
19:23 V_S_C only requires perl that came with git

19:23 dalek tablets: add set ops to A and link to B
19:23 dalek tablets: review:
19:23 flussence "perl that came with git" sounds... really really wrong.
19:23 leont git depends on perl, so git on windows ships with a perl 5.8.something
19:23 flussence don't you have Strawberry Perl or similar installed?
19:23 flussence oh
19:24 flussence yeah, 5.8 ain't gonna work at all here
19:24 TimToady there's nothing says we have to treat Ruby exactly like Perl 5 though, or vice versa; making them read identically would come down to a foolish consistency in my estimation
19:24 ZoffixW V_S_C, what does perl -v tell you? Which version?
19:24 nine hankache: you shouldn't have pointed out that blog post. Now I lost all motivation I've ever had for fixing the issues pointed out there.
19:24 moyamo Anyone want to play code golf?

19:28 kittenlips hi there
19:28 moyamo ZoffixW: I meant on a specific problem.
19:28 ChoHag Where in github
19:29 moyamo ZoffixW: Haha
19:29 nine ShimmerFairy: FWIW I remember quite well using "git merge" for merging curli. I'm sure about that, because merge is really the only way to merge a branch in git. rebase won't do it. So you displaying your ignorance of git really reflects more on you than anyone else.
19:29 kittenlips I was testing hyperoperators on Rakudo+MoarVM 2015.12 and have question are hyperoperators automatically multithreaded/parallelized?
19:29 nine kittenlips: not yet
19:29 kittenlips I thought I read that they were
19:29 masak kittenlips: on paper, yes.
19:30 itcharlie joined #perl6
19:30 V_S_C @ZoffixW, It happens when updating submodules for MoaRVM
19:30 masak kittenlips: the potential is all there.
19:30 moyamo I'm new to perl and I wrote this code:​#pjdakf4E/cagToxj9e8ZtKJ+2o2hHtuzR2ig92Ctxv0= . I was hoping someone could make it shorter or better :), for learning purposes.
19:30 kittenlips Oh ok, yes I tested it e.g. my int @matrix[50;40;30]; @matrix >>+=>> 1; and saw that MoarVM only was executing a single thread
19:30 V_S_C Configuring native build environment............. fail
19:30 hankache nine please don't lose your motivation ;( I feel bad now asking about it.
19:30 awwaiid TimToady: Yeah true. I'm taking all the top stuff out of the Ruby-Nutshell doc, I only left it in temporarily as food for thought.
19:31 cygx V_S_C: I think moar's takes some values from the Perl it's run with
19:31 hankache kittenlips i think it is planned for the future
19:31 cygx you can overwrite those manually
19:31 El_Che gfldex: I am reading to open the repo of StrictNamedArguments (adding travis support now)
19:31 Skarsnik hm, I have a git/github question. I PR a fork into my fork of DBI and later PR it back on DBI, does it keep the original author/fork?
19:32 leont cygx: it does? Why do we even need perl if we're not even doing our own config detection?
19:32 El_Che gfldex: just the README need some more info
19:32 kittenlips This automatic multithreading/parallelization of such operations will be a HUGE thing in data analysis, I think it is a killer feature of Perl 6
19:32 El_Che kittenlips++
19:32 ZoffixW kittenlips, basically the Perl 6 language spec defines them as threadable and now that it's frozen, they definitely will be, but that's not yet finished in the Rakudo compiler
19:32 nine hankache: no worry. I can hardly fault you for ShimmerFairy's talent for pushing away help.
19:32 ZoffixW m: sleep 1 for ^4 .race: :1batch; say now - INIT now
19:32 camelia rakudo-moar 75e33f: OUTPUT«1.00945432␤»
19:33 Skarsnik nine, you should write a small tibit for package maintainer about precomp file and such, reading the whole gist it's quite discouraging
19:33 ZoffixW kittenlips, ^ that works though. 4 sleeps in 1 second
19:33 cygx leont: *shrugs* it's a grown system
19:33 cygx leont: before the jit came along, it even supported cross builds
19:33 kittenlips ZoffixW: is ^ for the range operator?
19:33 kittenlips sorry I'm still trying to learn the language, it's much deeper than Perl 5
19:34 ZoffixW kittenlips, yes, ^4 is same as 0 .. 3, which is same as 0, 1, 2, 3
19:34 ChoHag Or, you could document precompilation quite thoroughly.
19:34 kittenlips ZoffixW: and you are saying ^ is parallelized?
19:34 cygx V_S_C: you probably need to set --os=win32 --toolchain=msvc
19:34 ChoHag Once the sky-is-falling release bugs are out of the way, which seems to be largely the case, perl 6 and its ecosystem needs lots and lots of documentation.
19:34 awwaiid kittenlips: naw, it is the .race that does the parallel bit
19:34 ZoffixW kittenlips, no, it's the .race/.hyper methods that return a HyperSeq

19:36 skids smls: see my last two camelias, something is up there.
19:36 kittenlips ZoffixW: oh! sorry I missed that in the IRC list
19:36 Skarsnik skids, method has 2 extra parameters, one at the begining and one at the end
19:37 Skarsnik but it's probably not your issue x)
19:38 skids Skarsnik: ?
19:38 smls I guess it makes sense for sort to use the 'cmp' from its own lexical scope
19:38 llfourn joined #perl6
19:38 smls Rather than the one from user scope
19:39 skids I dunno,
19:39 smls still, would have been nice if there were some way to make custom types work with the built-in ordering/sorting functionality
19:39 nine smls: sort does have a :&by argument
19:40 nine smls: if you really want to avoid that, you can still override your class' .Stringy method, because cmp compares on .Stringy
19:40 skids Yeah, but the point is making a type behave like base types in your lexical scope.
19:41 timotimo nine: i think leg compares by .Stringy
19:41 skids I'd say there's an argument to be made  for sort taking its default cmp from its caller's scope.
19:41 nine timotimo: src/core/
19:41 timotimo and cmp is "magical"?
19:42 * skids wonders whether that is touched on in roast at all.
19:42 smls skids: Or provide an upperclass method to implement ordering for your type (like AT-KEY and friends for implementing subscripting)
19:42 timotimo ah, .Stringy is the fallback for "not numeric"
19:42 cygx timotimo: where magical means do the right thing for numbers, otherwise fall back to...
19:42 cygx what you said ;)
19:45 skids sidenote -- introspection rocks, didn't have to debug to see what was up.
19:45 yurivish just thought I'd mention that I ran into this exact problem (​erl6/2015-12-15#i_11719526) today, in case it happens to influence a design decision to change the behavior down the line :-)
19:45 yurivish where you can't say { *.method ~~ regex } as an argument to grep
19:45 ChoHag joined #perl6
19:46 * ZoffixW has something to pitch in on the topic:

19:47 ZoffixW ^ that requires "not matches" to be written much more verbously than "matches"
19:47 V_S_C cygx probing whether your compiler thinks that it is gcc  Can't compile simple gcc probe, so something is badly wrong at build/ line 92.
19:47 nine Skarsnik: your commit 532c11abbcc8409a03d4a585296149f94c219e08 broke Inline::Perl5: Too many positionals passed; expected 2 arguments but got 3
19:47 ZoffixW Unless I just don't know a way :D
19:47 Skarsnik oh great :(
19:47 Skarsnik what line trigger it?
19:48 nine Skarsnik: seems to break on sub p5_str_to_sv(Perl5Interpreter, long, Blob)
19:48 cygx V_S_C: are you manually building moarvm, or implicitly via rakudo?
19:48 Skarsnik wait Blob work?
19:49 perlpilot ZoffixW: you've just got to use {}  (which may be onerous, I dunno)
19:49 perlpilot (its' a good habit to get into anyway IMHO)
19:49 skids smls: OT, more thoughts on binary structured matching/unpack here:

19:50 ZoffixW k, I see why the error happens now. perlpilot++
19:50 Skarsnik This code is not fun to debug since it happend at compile time x)
19:50 yurivish The documentation for prefix ! says "Coerces the argument to Bool by calling the Bool method on it, and returns the negation of the result. Note that this collapses Junctions." How is it that matching on !/2/ works?
19:51 cygx yurivish: boolifying a regex matches it against $_
19:51 yurivish oh, wow
19:51 V_S_C cygx I am following
19:52 V_S_C As msi is older I am building from source

19:58 Skarsnik nine, well a quick fix is to add | 'Blob' aside 'Buf'
19:58 V_S_C Now after newer windows release git installer settled the default perl for me
19:59 smls skids: That sounds really interesting, though I think I'd have to see some examples to properly understand it... :)
20:00 smls In any case, I agree now that a more structured OO approach is preferable to my initial free-form grammar approach for most use-cases.
20:00 nine Skarsnik: confirmed
20:00 Skarsnik I am not even sure how this test work
20:00 Skarsnik but it's a bad fix x)
20:01 Skarsnik I just did not know to know if a type is totaly 'defined'
20:01 El_Che I want to push a module to the ecosystem. What's the best practice for doc? perl5 pod in the file? something else?

20:12 Skarsnik timotimo, is there a way to know if a type is 'complete' at "compile time". I use ^can(gist) because I assume for complete type it exist at​blob/nom/lib/NativeCall.pm6#L210
20:12 timotimo you can probably check its HOW against CurriedRoleHOW or what it's called?
20:14 hankache smls thnaks
20:14 hankache thanks**
20:15 kittenlips joined #perl6
20:15 timotimo it'd probably be more correct to check its primitives or what they are called
20:15 hankache ZoffixW while you're at it the Advent Calendar box is a bit out of sync
20:15 timotimo archetypes*
20:15 Skarsnik I am not really searching if how is set on it. it just if I have class B {}; class A { sub foo(B) is native} The rest of the code work because B is 'defined' intierly (this code is executed when is native is see) but in case of class A { sub foo(A) is native} perl 6 does not have the full definition of A
20:16 ZoffixW hankache, dammit :P now that you've noticed it I'll just *have* to fix it ^_^
20:16 timotimo oh
20:16 skids smls: it looks like a case could be built from RT#125049 up to getting all such stuff to take their default comparitors from calling scope, assuming rt gets resolved in favor of that.  (Fudged tests for it are in S03-sequence/nonnumeric.t)
20:17 Skarsnik and for the weekly post. I don't know, lot of change in precomp/build system to accomod distrib?
20:17 hankache ZoffixW hehe
20:17 timotimo all i can say is: look in the files in src/Perl6/Metamodel
20:17 lizmat .tell autarch thinking more about Olson, I think wrapping .later and adjusting the timezone with .in-timezone, should be enough

20:21 smls *hankache
20:21 ChoHag Is that because the --doc parser is really simple or have I written the documentation incorrectly?
20:22 Skarsnik both?
20:22 Skarsnik I mean the first
20:22 RabidGravy doc parser is really simple
20:23 ChoHag So when the doc parser is improved, that docomment will be headed correctly?

20:58 flussence s[it][it or the browser]
20:58 timotimo mostly because of the call graph being unlimited depth
20:59 timotimo jast: we have a Grammar::Tracer module in the ecosystem
20:59 timotimo that's very nice
20:59 timotimo otherwise you can put { say "here: 1" } into your regexes as well
21:00 perlpilot using say like that is a very effective technique :)
21:00 jast good idea
21:00 masak note that that may screw up LTM, though
21:00 masak since any code ends the declarative prefix
21:00 perlpilot yeah, that's the major down side
21:01 jast and that module is even pre-installed by Task::Star apparently
21:01 perlpilot I wish there was a way to have the compiler inject {say "enter $regex"} and the equivalent exit in all of the regex for a grammar (without messing up LTM)

21:03 tadzik but it doesn't crash your browser on a big program, so there's that :)
21:03 perlpilot I guess I want something in between Grammar::Tracer and manual insertion of say statements.   Maybe I'll write one ... one day .... maybe  :)
21:03 tadzik and to be the devil's advocate, Qt's JSON parser still can't handle CORE.setting profile iirc
21:03 jast well, the tracer (actually called Grammar::Debugger now) pointed me right at the problem.

21:14 flussence I think we really ought to do a 2015.12.1 rakudo just for the sake of getting rid of the "can't mkdir"
21:14 timotimo  -  should this excerpt from Synopsis 1 be replaced by something else? or should that part of Syn 1 be reworded now that the release has happened? TimToady?
21:14 timotimo flussence: yeah ...
21:14 tadzik I think it speaks badly about Rakudo's installation process that people are trying to use rakudobrew as a tool to have a system-wide perl 6 installation
21:14 tadzik (or about our documentation)
21:14 mojca who can help me with /opt/local/bin/perl6 then?
21:14 pierre-vigier joined #perl6
21:14 Skarsnik proabably the doc
21:14 tadzik I hope we can :)
21:14 timotimo before the star release, a little rakudo bugfix release would be nice
21:14 mojca it works if I call it directly, but not in shebang or whatever that is called
21:14 flussence tadzik: I haven't touched rakudobrew *ever* :D
21:14 tadzik mojca: what does 'file /opt/..." say?
21:15 tadzik flussence: sounds like it saved you some potential trouble :P
21:15 mojca it's #!/bin/sh
21:15 tadzik mojca: is it executable?
21:15 flussence (in fact, I'm doing as much work as I can to make sure nobody ever does...)
21:15 mojca with exec /opt/local/bin/moar  --execname="$0" --libpath="/opt/local/share/nqp/lib" --libpath="/opt/local/share/perl6/lib" --libpath="/opt/local/share/perl6/runtime" /opt/local/share/perl6/runtime/perl6.moarvm "$@"
21:15 Skarsnik On my dedicated server I have a system wide perl6 installed with
21:15 tadzik kredit to team :)
21:15 mojca POSIX shell script, ASCII text executable
21:15 mojca it's 755
21:15 Skarsnik I think what is not clear with that is you have to NOT put --prefix to to install Panda
21:15 tadzik how did you install it there, btw?
21:16 tadzik our entire toolchain is built around the idea of keeping things in your $HOME
21:16 mojca how did I install rakudo or panda?
21:16 spider-mario joined #perl6
21:16 tadzik seems like it backfired and we never checked how it actually works outside
21:16 tadzik mojca: both
21:16 mojca me and [Coke] cooked up a package
21:17 tadzik well, if hello world doesn't work then it seems to me like te package is broken somewhere
21:17 mojca so MoarVM, nqp, rakudo were built with the package manager
21:17 mojca this works: /opt/local/bin/perl6
21:18 mojca just "#!/opt/local/bin/perl6" doesn't and I would suspect it's because of the contents of that script
21:18 mojca I made a package for Panda as well, but the package for panda still misbehaves because I don't know how to install it
21:18 mojca I don't want it in $HOME
21:19 Skarsnik I think panda try to find where perl6 is located and put itself there?
21:19 mojca but I would like to convince panda to install modules somewhere under $HOME/.perl6 or something similar, like cpan puts modules under $HOME/.cpan
21:19 RabidGravy mojca, the perl6 script is a wrapper in Perl 5
21:20 RabidGravy well it is here
21:21 mojca is it theoretically possible that it would work as "#!/opt/local/bin/perl6"?
21:21 Skarsnik Not wanting to bash curli stuff, but it really look it never really get tested on a "real world" use case ~~
21:21 jast if I recreate a similar situation with my rakudobrew-based installed (#!/a/comparable/script), it works
21:21 nine mojca: have you tried panda --prefix $HOME/.perl6/2015.12-41-g461e635 (or whatever is current for you)?
21:21 flussence Skarsnik: hard to test it on a real world use case when there weren't any real world users...
21:21 mojca is --prefix meant for destination of modules or for location of panda itself?
21:22 RabidGravy oh wait that's the rakudobrew shim, the default one is just sh
21:22 jast I tried with both the shim and the shell script, so it's theoretically possible for it to work
21:23 mojca wait ... perl6 actually *TALKS*????
21:23 nine Skarsnik: well it did work in all the real world use cases that I knew of. Once you're at that point, you have to merge to give it a wider audience.
21:23 nine mojca: --prefix=/path/to/modules    Place to put modules, executable scripts, etc.
21:23 mojca ouch, I misunderstood it then
21:23 mojca I need to fix that then
21:23 Skarsnik what --prefix does on ?

21:25 nine mojca: --prefix was obviously not enough during creation of the panda package, but it should be enough once panda's installed
21:26 Rotwang Hi, it appears that NativeCall doesn't try to resolve library path, so by default you need to provide library with a full path?
21:26 jdv79 not bad craft beer bars in amsterdam.  im a little surprised.
21:26 Skarsnik How I mark a bug ia duplicate of another on RT?
21:26 mojca I'll try to reinstall with a different --prefix
21:26 Skarsnik Rotwang, no​tivecall#Library_Paths_and_Names
21:27 flussence Rotwang: if it isn't in the standard LD_LIBRARY_PATH, you'll have to give it a full one, yes
21:27 mojca but then one more thing, what should I do with the state file
21:27 Skarsnik Ah yes, I should maybe add that it search in the system linker path (or something like that)
21:27 mojca it contains lots of weird temporary paths that get deleted
21:28 nine mojca: actually, panda even tries to be smart about picking installation locations and it should fall back to $HOME/.perl6 if the site repo is not writable. Obviously this does not yet work as intended. Could be less work to actually fix that bug than to work around it.
21:28 mojca after the installation is complete
21:28 CQ joined #perl6
21:28 nine masak: I'd be happy to see panda's state file replaced by a proper API in Perl 6 and have already begun work on the latter.
21:28 mojca falling back to $HOME/.perl would help
21:29 Skarsnik for me panda should do this: root run it -> default system prefix; user -> $HOME
21:29 mojca if you think that this could be implemented soon, I'll rather wait than try to reinvent the wheel
21:29 tadzik it can be arranged
21:29 tadzik but I'm pretty sure it does in fact fallback to $HOME/.perl6
21:30 tadzik if everything else goes t hell
21:30 nine tadzik: there's certainly code for that. It may just be some stupid bug preventing it. Or maybe it does work after all and nobody has tried it yet ;)
21:31 flussence tadzik: worked for me. I installed rakudo to system dirs, and panda install Linenoise both Just Worked
21:31 flussence (as unprivileged user, that is)
21:31 mojca I get
21:31 tadzik nine: the latter is quite possible :)
21:31 Skarsnik gah RT does not have a marked as duplicate or something?
21:31 timotimo Skarsnik: you can merge tickets
21:32 mojca I need to add that I didn't install the state file though because I have no clue where it belongs and what to do with temporary path that gets removed
21:33 mojca can someone explain what the error is trying to tell me?
21:34 Rotwang flussence: Skarsnik: thanks for the info, although there is no "standard" LD_LIBRARY_PATH (by default it is empty) and the library resolution on linux is relatively coplicated (ld cache and so on)
21:34 mojca why are all filenames "encrypted"?
21:34 mojca from the error log it's almost impossible to tell which file is throwing the error
21:35 timotimo agreed
21:35 mojca also, when panda is done bootstrapping, it tells me "==> Please make sure that inst#/opt/local/var/macports/build/_path_to_perl​_lang_panda/panda/work/.home/.perl6/2015.12/bin is in your PATH"
21:35 timotimo however, the paths still give you a file you can read
21:35 timotimo for the source
21:35 Arrowhead using NativeCall, is there a way to call through a C function pointer?
21:35 mojca which is nonsense because that temporary build dir will eventually get removed
21:35 _nadim joined #perl6
21:36 mojca tomotimo: yes, but it's useless for anyone trying to decrypt what my logs say without having access to my machine
21:36 timotimo Arrowhead: i've wished for this in the past, but we don't have support for this IIUC
21:37 Skarsnik Not sure to understand why to you mean call through a C function pointer? You mean you get a function pointer and want to call it?
21:38 Arrowhead timotimo: That's a shame. I'm doing OpenGL stuff and I can successfullly call things that are in the GL shared lib. But I understand that more modern functions are only available as pointers. Even when using GLEW it looks like the shared lib only has pointers, not actual functions.
21:38 Arrowhead Skarsnik: exactly
21:38 llfourn joined #perl6
21:39 Skarsnik Oh right, hm, sound tricky to do
21:40 Arrowhead Ultimately the functionality must be there, the question is: how to expose it.
21:40 brrt Arrowhead, maybe you can use csymbol?
21:41 Skarsnik I never really looked at how functor work
21:41 Arrowhead brrt: you mean symbol('foo') unfortunately no, that assumes foo is a function.
21:41 RabidGravy A work around would be to make some additional C code that does the dispatching
21:41 mojca nine: if talking about falling back to $HOME/.perl6 for panda: is there any ticket I could follow (I probably won't be on IRC like I was yesterday when you fixed the problem when that will be discussed)
21:42 skids mojca: it's not that the filenames are encrypted it's that rakudo doesn't necessarily use files to identify compunits.  Theoretically it will allow installing multiple versions of the same "file" in case one app needs a newer version that another app cannot use, or other such things.
21:42 Skarsnik RabidGravy, probably yes
21:42 timotimo Arrowhead: in any case, you can use Inline::C to compile little stubs for you that call the function pointer ...
21:42 timotimo just treating the function pointer as OpaquePointer and build one C function for every different argument signature
21:42 Arrowhead ah, is that there too in perl6 land. I'll have a look.
21:42 timotimo sounds terrible. and it is. ... ... sorry :(
21:42 brrt Arrowhead:​nativecall#Exported_variables
21:42 brrt is what i mean
21:43 Skarsnik It does not sound that bad to add? like creating a special Callable?
21:43 timotimo yeah, should be easy. you go ahead! :)
21:44 Rotwang it may be a silly question, but where are the sources of NativeCall? I guess it is no longer Zavolaj
21:44 Arrowhead brrt: that's for reading/writing variables for which you know the name. I want to call the C code.
21:44 Arrowhead Rotwang: in rakudo
21:44 Skarsnik NC is in Rakudo/NQP/Moar
21:44 RabidGravy It can already marshal Callables to function pointers so I wonder if the reverse could be done
21:45 niceperl joined #perl6
21:45 firstdayonthejob joined #perl6
21:45 Skarsnik C wise how that work with using dlopen and doing it?
21:45 Rotwang Arrowhead: Skarsnik: thanks
21:46 Skarsnik but if you have issue with your libpath you can ask x)
21:46 RabidGravy well if you already have a function pointer in hand then you don't need to load it from a dll surely
21:47 brrt oh wow...
21:47 timotimo RabidGravy: well, that's not really the same thing, as it has to create a piece of code that can be used as a target for function pointers to invoke
21:48 Skarsnik yes RabidGravy but are in the case of we don't link the lib at compile time. so it's dlopened and I don't remember how function work in this case in C
21:49 RabidGravy timotimo, sure
21:49 keix joined #perl6
21:49 timotimo well. it could certainly be super crazy easy to make. maybe not. who knows.

21:50 yurivish_ joined #perl6
21:50 RabidGravy jdv79, very possibly but hey
21:51 Skarsnik timotimo, I am pretty sure it's passing around the sub signature to C (Moar) and its pointer and call it
21:51 jdv79 hey!
21:54 timotimo Skarsnik: you can have a look at MoarVM to see how "nativecallbuild" and "nativecallinvoke" are implemented
21:54 autarch lizmat: it's a little more complicated than just wrapper later - with Olson time zones there are things like non-existent local times as well as local times that are ambiguous (yeah have hour 2 twice in a row)
21:54 yoleaux 20:17Z <lizmat> autarch: thinking more about Olson, I think wrapping .later and adjusting the timezone with .in-timezone, should be enough
21:54 CQ left #perl6
21:55 lizmat autarch: the non-existant local times are no issue
21:55 Skarsnik timotimo, I will have a quick look tomorrow
21:55 autarch lizmat: why?
21:55 timotimo cool.
21:55 lizmat because you can never move into them
21:55 lizmat .later is already technically correct
21:55 lizmat only the timezone of the resulting object isn't
21:56 perlpilot lizmat: users can't create localtimes that don't exist?
21:56 lizmat I'm saying you can't move into them using .later
21:56 autarch lizmat: we may be talking past each other
21:56 perlpilot oh
21:56 lizmat if you specify a non-existing time on creation, it should die
21:57 autarch lizmat: right, that's somewhat of an API change, and it constantly surprises users of p5 DateTime
21:57 autarch this is one of the reasons I proposed have a DateTime class without timezones and another one with them
21:57 autarch a lot of people don't actually need _any_ tz handling whatsoever and would be better off with a class that doesn't ever make them think about this
21:58 lizmat but with the current implementation, you can't go wrong with the timezone, it's basically just a view on the actual underlying atomic clock time
21:58 lizmat if you don't specify a :timezone with DateTime, you don't have to think about it
21:59 lizmat moving from non-DST to DST with anything other than seconds, will DTRT
21:59 perlpilot In the past, I've wanted offsets from UTC without necessarily caring about timezones, but I don't know how common/useful that is
21:59 lizmat atm, you can have offset you want  :-)
22:00 lizmat and there are actually tests for them
22:00 autarch perlpilot: it's not uncommon - it's easy to support along with Olson zones
22:01 autarch lizmat: what you think is DTRT is not necessarily what others will think is DTRT - have you read p5 DateTime's docs? they go into a lot of the different cases that should be considered
22:01 lizmat ok, will do so before getting back to this  :-)
22:02 perlpilot lizmat++
22:07 nine mojca: frankly I find it very tedious to try and fix those issues. I cannot reproduce them and have no idea how all this OS X packaging stuff works and where ridiculous paths like inst#/opt/local/var/macports/build/_path_to_perl​_lang_panda/panda/work/.home/.perl6/2015.12/bin come from.
22:07 autarch lizmat: you might also find​esentations/a-date-with-perl/#1 interesting
22:08 nine mojca: do you think, you can do a little digging into panda's source code yourself? The error message comes from lib/Panda/ and the interesting code starts in line 11. It should be fairly self explanatory.
22:08 Skarsnik btw Mac os X vm work with VirtualBox
22:09 nine Skarsnik: maybe, but I'm certainly not gonna buy OS X to debug other people's systems.
22:09 Skarsnik Well you need patched a version of os X ~~
22:09 nine If people want to use a non-free system, they cannot expect me to go that far.
22:09 RabidGravy are there any of the developers who use os X ?
22:10 vendethiel lizmat does, afaik
22:10 perlpilot autarch: slide 19 has a typo  "inclues"  (though, that should be a word!)
22:10 autarch includes?
22:10 lizmat yes, I do, but i have given up on macports: it always gave me more pain than gain
22:10 perlpilot aye
22:10 RabidGravy it is in french isn't it?
22:11 Skarsnik and virtualbox still does not see intel vx tech, so I can't boot any 64 bit vm, :(
22:12 diakopter I have 64-bit VMs in virtualbox, I thought
22:12 jast with a windows host that tends to happen if its own hypervisor (hyper-v) gets in the way, maybe something similar on osx?
22:12 Skarsnik Yes, but my virtual box version get lost sometime
22:13 Skarsnik I am on win7 and I don't have hyper-v
22:13 jast right, hyper-v is included starting with win8
22:13 Skarsnik it's a weird bug that does not always happened
22:14 jast I didn't ever have these types of issues with win7, but apparently I just had better luck :/

22:31 kittenlips hi, question about syntax highlighting, are there syntax highlighting tools that actually load and understand the full grammar for a language to produce very informative highlighting to really aid in comprehension of code?
22:31 lizmat jdv79: I'll talk with him about it...
22:31 jdv79 ah.  we exchanged emails once and he was a maybe.  i need to reply.
22:32 ZoffixWin nine, BTW, good job with the whole pre-compilation stuff. Before it, perl6's startup stuff was driving me nuts and now performance doesn't even come to mind when I write my stuff :) I'm glad we didn't have that slowness when we released, or I imagine lots of people would be complaining about it ^__^
22:33 jdv79 that would be cool though.  so far ill only be in amsterdam til the 2nd.  when is thus pm meeting?  should i go?
22:34 jdv79 its not a big deal though:)
22:34 kittenlips I've always found syntax highlighters for Perl such as those in Padre or what we see in online resources such as in Github to be either plain wrong or just really lacking
22:34 lizmat the Amsterdam PM meetings are on the first Tue of the month, so on the 5th this time
22:35 jdv79 hmm...
22:36 flussence kittenlips: the highlighter in pygments is top notch. It was written specifically *for* Github even, then they threw the entire thing away for the sake of NIH/avoiding python-cooties...
22:36 ZoffixWin kittenlips, yeah, it's a tough language to highlight due to contexts and stuff. MadCapJake++ wrote a nice plugin for Atom with superb highlighting (
22:37 ZoffixWin kittenlips, I heard there's something for vim too
22:37 Skarsnik vim highlight is slow for me
22:37 kittenlips flussence: the pygments highlighter is what is being used on the Perl 6 site no?
22:38 flussence yep
22:38 Skarsnik like I thought I was using some 80 internetspeed editing a 100 lines file via ssh x)
22:38 ZoffixWin Is it?
22:38 ZoffixWin Oh on docs
22:38 ZoffixWin I think the examples on homepages were made with Text::VimColour
22:39 llfourn joined #perl6
22:39 flussence vim-perl works fine too, the version bundled with vim is ancient though
22:40 Skarsnik it's maybe a dumb question, but why the doc for class are not in the class itself using WHY stuff of pod? because pod parser is bad, or it was too slow?
22:40 kittenlips By no means to criticize as I know it's likely a difficult task, but even on Perl 6 docs the highlighting could go further
22:41 timotimo it's definitely a task ...
22:41 kittenlips For example variables within strings should be highlighted with the same color as the variable outside and different than regular string characters
22:42 perlpilot Skarsnik: too slow
22:42 Skarsnik maybe with precomp it's not true?
22:43 q0tw4 joined #perl6
22:43 kittenlips that's why my question about are there syntax highlighters that can just import the grammar for a language and understand it so that it automatically creates the correct highlighting patterns without any user configuration
22:44 perlpilot kittenlips: "I want my identifiers to be green"  "I want mine to be red!"   (there will always be "user configuration")
22:45 ZoffixWin Skarsnik, I think it's because the docs are meant for any Perl 6 implementation, not just Rakudo. Another issue I can see the separation solves: you can give commit access to a much greater number of people to docs alone, than to docs + implementation.
22:45 Skarsnik kdevelop color each variable with a dif color for example
22:45 kittenlips perlpilot: well not the colors, but that the highlighter knows that here is an identifier <- let user decide color
22:45 Begi2 joined #perl6
22:45 kittenlips So that user doesn't have to configuration how the syntax highlighter understands the syntax, the grammar should tell the highlighter that without any user configuration
22:45 Skarsnik ZoffixWin, I think it make keeping the doc up to date harder ~~
22:46 ZoffixWin Skarsnik, maybe. But, to play the devil's advocate, do you want some l33t h4x0r spend their time writing docs or writing code, and leaving someone with less skill to read the completed code and write the docs? :)
22:47 ZoffixWin Dunno, I have a strong bias against spaghetti Pod + code, :)

22:54 Skarsnik well perl6 is parsable by.. perl 6

23:00 ZoffixWin ehehe. I love Perl 6 :P
23:01 Juerd If Perl cannot be parsed, and Perl 6 can be parsed, then Perl 6 is not Perl? I'm confused.
23:01 Skarsnik Does someone try to build a perl5 interpreter with Perl 6? x)
23:01 flussence no, it just means your definition of "parsed" is wrong
23:02 flussence (or "cannot")
23:02 kittenlips Juerd: sorry Perl 5 cannot be parsed without actually running the program as well
23:02 flussence (or "be"... ah, forget it)
23:03 shicheng joined #perl6
23:04 kittenlips Juerd: the Perl Monks article is about Perl 5 that it is impossible to statically parse.  I believe Perl 6 can be statically parsed?
23:04 ZoffixWin Can it?
23:04 cpage_ joined #perl6
23:04 ZoffixWin Perl 6's magicness looks way more advanced than Perl 5's :o
23:05 kittenlips Can Perl 6 code be parsed without actually running the code?
23:05 Skarsnik seems unlikly x)
23:05 kittenlips hehe
23:05 lizmat think BEGIN blocks ?
23:06 lizmat think 'use something' that changes the slang
23:06 RabidGravy well in the sense that you can get an abstract syntax tree then yes
23:06 kittenlips lizmat++ yes because bluring the lines between compilation and runtime
23:06 ZoffixWin kittenlips, based on how I understand that monger's argument, my examples of custom operators above show an even more extreme example. How would such a parser know that, say /((((/egahgs/ is actually an operator that I defined in some other package?
23:07 ZoffixWin m: sub infix:</((((/egahgs/> ($a, $b) { say "$a $b" }; 'Just' /((((/egahgs/ 'testing'

23:08 Skarsnik I am not sure I want to know

23:10 kittenlips to everyone sorry about going on and on about syntax highlighting etc.
23:10 cygx joined #perl6
23:10 flussence nothing wrong with genuine curiosity :)
23:10 kittenlips Just Perl (5 and 6) are languages that of any language need as good syntax highlighting as possible
23:11 cygx v5 has suffered a severe case of bitrot
23:11 kittenlips It's extremely dense code with many symbols and operators and having very detailed highlighting really helps with code comprehension
23:11 * ZoffixWin glances at mst, who doesn't use any highlights and loves it :)
23:11 cygx I made it 'work' (with some issues related to the GLR), but precomp broke it again
23:12 cygx I'm still planning to get back to it, eventually
23:12 ZoffixWin Not just loves it, but argues it makes reading the code better.
23:12 flussence p6 does a lot better than just syntax highlighting, try it with the Fira Code font sometime :)
23:13 kittenlips Personally in all my years programming Perl 5 I used NEdit as I found out of the box it had the best and most detailed syntax highlighting
23:13 virtualsue i love syntax highlighting
23:13 kittenlips I believe NEdit's syntax highlighting engine uses regex that's how it could be so good
23:13 timotimo "detailed" syntax highlighting? sounds like it highlights individual parts of letters differently, too :P
23:14 kittenlips yes, it actually individually highlighted within regexs EXACTLY how it should be
23:14 flussence timotimo: that's also called "misconfigured Cleartype" :D
23:14 virtualsue i just generally take it as i get it, and don't care about the details
23:14 Skarsnik I use a different ide/editor for the language I work with x)
23:14 kittenlips virtualsue: hehe
23:14 kittenlips Skarsnik: me too
23:14 kittenlips with Perl 5 -> NEdit
23:15 RabidGravy yeah, I only find it really really useful because sometime I can't tell the difference between quote characters
23:15 Skarsnik C => kdevelop, C++ QtCreator, Perl 6 => kate
23:15 shicheng joined #perl6
23:16 lizmat good night, #perl6!
23:16 kittenlips I find with Perl 5 my brain needed good syntax highlighting in order to comprehend code easily
23:16 kittenlips With Java and Python it doesn't matter
23:16 flussence too much syntax highlighting can be a terrible thing: php.vim has an option to sub-highlight heredocs that use delimiters like "HTML" and "SQL"...
23:16 RabidGravy if the rest of the file is read after a quoted string, I typed the wrong quote character
23:16 Skarsnik Lol
23:16 RabidGravy red
23:17 ZoffixWin this is the best editor:
23:17 ZoffixWin ^_^
23:17 ZoffixWin *cue heavy metal music while coding*
23:17 colomon joined #perl6
23:18 kittenlips LOL
23:18 kittenlips Bang! Bang!
23:18 Skarsnik I need that!
23:18 flussence (and once upon a time, some idiot sitting in my chair thought it was a really neat idea and turned all those php.vim options on then proceeded to *make use of* them...)
23:18 ZoffixWin Oh man, it even exists for Atom :)
23:18 kittenlips I tried to install Atom from source, my God it just never works I HATE node.js
23:19 ZoffixWin It's what I use for Perl 6 'cause Sublime Text 2 has bad P6 highligher :(
23:19 kittenlips The servers I have at work are not latest Linux distros, only CentOS 6.7 and Atom will not build from source anything but newer Linuxes
23:19 kittenlips And they don't tell you that
23:20 deniska I need the activate power mode in my terminal
23:21 Skarsnik rakudo build need power mode
23:21 deniska That way pretty much every program I use can be power moded
23:21 deniska irssi power mode :)
23:21 kittenlips Let me rephrase, I don't hate node.js but I just couldn't get everything to compile it doesn't tell you you need fairly new glibc versions
23:22 RabidGravy I've installed it on ancient versions of SLES before
23:22 RabidGravy for my sins
23:22 cygx # RFC: make v5 pluggable
23:23 kittenlips why does power mode remind me of Street Fighter?
23:24 kittenlips Hadouken!!!! Alllyouken!!
23:25 flussence cygx: er, why not make use of the multiple-versioned-same-named module support we already have?
23:25 mojca tadzik, I found this reference:​rious/shebang/#interpreter-script claiming that nesting shebang scripts might be problematic (while working on newer linux)
23:26 mojca but it's my fault anyway, so it's me the one who has to address the problem
23:27 cygx flussence: it's not about the version specifically, and I don't think it's a good idea to disambiguate sematically distinc modules solely by authority
23:28 kid51 joined #perl6
23:28 cygx flussence: a module could implement Perl5 via a proper slang, or just do some quote parsing and hand off the actual processing to Inline::Perl5, or something completely different
