00:00 mort96 hey
00:00 Ulti then the .grep(Even) worked the same as the .grep(Int) it found things which were of type Even which are Ints that also satisfy %% 2
00:00 mort96 I now have perl 6 installed :)
00:00 Ulti and Linux at the same time? :3
00:00 AlexDaniel m: my Int subset Even where * %% 2; my Even $x = 24
00:00 camelia rakudo-moar a7ea8e: ( no output )
00:00 AlexDaniel m: my Int subset Even where * %% 2; my Even $x = 25

00:00 herby_ Ulti, thats pretty dang cool
00:00 mort96 ya, /bin still exists
00:00 AlexDaniel herby_: ↑
00:01 mort96 _both_ perl6 _and_ system binaries
00:01 Ulti m: my Int subset Even where * %% 2; my Even subset SmallEven where * < 25; my SmallEven $x = 25;

00:01 Ulti you can see how it could eventually get crazy :S
00:02 herby_ hah yeah
00:02 Ulti herby_ you can use the where keyword in parameter lists too
00:02 Ulti so you can have multi dispatch on a method or function with those sorts of constraints

00:33 Ox0dea AlexDaniel: Still not clear what you're asking?
00:33 Ox0dea You can say `Date.today.next_month(6)` to fast-forward half a year.

00:34 Ox0dea nine: Y U DO DIS?
00:34 lucasb oops, I was evaluating something... have I killed her?
00:34 ShimmerFairy herby_: unless I'm horribly mistaken, we have all the suffixes for english ordinals for regexes there (so, :st, :nd, :rd, :th), but the "general" form is :nth, which can be clearer in cases like :nth($x) or whatever :)
00:35 ShimmerFairy lucasb: did you try to invoke nqp-p by accident?
00:35 lucasb just 'nqp' :)
00:35 lucasb is that trouble? /o\

00:35 lucasb ah, good :)
00:35 Ox0dea m: say "I'm alive!"
00:35 herby_ she isn't happy about being booted
00:36 ShimmerFairy Ox0dea: I can't recall, it's been a while since I touched on my Lingua::En::Numbers::Ordinal thing

00:48 AlexDaniel mort96: what's your question? :)
00:48 mscha p6: say τ.Rat;
00:48 camelia rakudo-moar a7ea8e: OUTPUT«6.283186␤»
00:48 mort96 with regexes, by default, whitespace isn't significant. However, a warning is emitted telling you to either remove spaces, or make whitespace significant.
00:48 mscha say τ.Rat.perl;
00:48 mort96 Why not just make whitespace significant in the first place?
00:48 mscha p6: say τ.Rat.perl;
00:48 camelia rakudo-moar a7ea8e: OUTPUT«<710/113>␤»
00:48 AlexDaniel mort96: well, in Perl 5 it turned out to be a bad idea
00:49 flussence [Coke]: nope, in my case it was the opposite: 2015.12 only builds when there's *already* an installed rakudo, because it reads existing stuff from that (which is wrong) instead of trying to mkdir there
00:49 mort96 so it's a backwards compatibility thing in perl 6?

00:49 mort96 I don't think 6 is backwards compatible anyways, is it?
00:49 AlexDaniel mort96: yes, kinda. So that people coming from Perl 5 will see it immediately. That's what I think
00:50 AlexDaniel m: say ‘hello’ . ‘world’

00:52 mort96 kind of weird of perl6intro.com to advertise the whitespace insignificance of regexes then, but idk if that's affiliated with perl 6 in any way or just community things

00:56 AlexDaniel gamo: well, yes, although that's not what the current implementation will do, I think
00:56 gfldex gamo: not right now, but it will be in the future. Be careful with side effects.
00:56 mscha p6: say "hello world" ~~ / 'o w' /

00:56 AlexDaniel gamo: but you should expect that it will be parallelized one day, yes
00:56 Ox0dea timotimo: Good. That's a terrible name.
00:56 mort96 I'd still probably point out that it's generally considered a bad idea to have insignificant whitespace and it thus emits a warning in the perl6intro page
00:57 AlexDaniel mort96: considered a bad idea by who?
00:57 Skarsnik isignifiant whitespace are good for readability
00:57 gamo thank you, all, specially Alex and gfldex
00:57 mort96 by whomever made perl 6 emit that warning when you have a regex with insignificant whitespace?
00:58 mort96 you yourself said it emits the warning because it was generally considered a bad idea in perl 5
00:58 mscha p6: say "hello   world" ~~ m:s/o w/
00:58 camelia rakudo-moar a7ea8e: OUTPUT«「o   w」␤»
00:59 ShimmerFairy mort96: for what it's worth, I've never managed to trigger the warning (though it probably helps I don't know what the conditions are for doing so :P)
00:59 [Coke] m: "JEEBUS IT'S LOUD IN HERE".say
00:59 camelia rakudo-moar a7ea8e: OUTPUT«JEEBUS IT'S LOUD IN HERE␤»
00:59 AlexDaniel mort96: I meant that significant whitespace was probably a bad idea
00:59 AlexDaniel mort96: because people ended up writing unreadable regexes
00:59 AlexDaniel mort96: sorry for the confusion
01:00 mort96 "hey" ~~ /n o/ triggers it
01:00 AlexDaniel m: “hey” ~~ /n o/
01:00 camelia rakudo-moar a7ea8e: OUTPUT«Potential difficulties:␤    Space is not significant here; please use quotes or :s (:sigspace) modifier (or, to suppress this warning, omit the space, or otherwise change the spacing)␤    at /tmp/E7LL3uLm61:1␤    ------> 3“hey” ~~ /n7⏏5 o/␤»
01:00 AlexDaniel m: “hey” ~~ /‘n’ ‘o’/
01:00 camelia rakudo-moar a7ea8e: ( no output )
01:00 AlexDaniel m: “hey” ~~ /‘n o’/
01:00 camelia rakudo-moar a7ea8e: ( no output )
01:00 AlexDaniel that is, just be explicit
01:00 Skarsnik The warning is annoying, I agree x)
01:01 mort96 so /'n' 'o'/ will match "no", while /'n o'/ will match "n o"? That kinda makes sense, had no idea about ''
01:01 Ox0dea What's the idiomatic approach to creating method aliases?
01:02 Skarsnik method aliases?
01:02 AlexDaniel mort96: yes
01:03 AlexDaniel m: say so “oh no” ~~ /‘n’ ‘o’/
01:03 camelia rakudo-moar a7ea8e: OUTPUT«True␤»
01:03 AlexDaniel m: say so “oh no” ~~ /‘n o’/
01:03 camelia rakudo-moar a7ea8e: OUTPUT«False␤»
01:03 mort96 then it seems like a great solution really, just a slightly confusing error message

01:18 timotimo does somebody, anybody, want to put a little bit of text or example about "put" onto the faq entry about print vs say?
01:20 mort96 what's the difference?
01:22 mort96 according to the docs, the difference seems to be that put uses the .Str method to stringify, while say uses the .gist method
01:23 timotimo aye
01:23 timotimo but put puts a newline, too
01:23 timotimo so put is a mix between print and say
01:23 mort96 the docs also seem to recommend to use put to generate machine readable output, and say to generate human readable
01:23 timotimo either this is very exhausting, or i'm just very exhausted
01:24 timotimo yeah, that's the difference between .gist and .Str
01:24 timotimo m: say (^10000)
01:24 camelia rakudo-moar a7ea8e: OUTPUT«^10000␤»

02:18 mort96 The more I'm reading about perl 6's OOP, the more I'm liking it
02:18 bpmedley Is there a good overview of Promises, Supplies, and Channels available?
02:19 llfourn bpmedley: you mean apart from: http://docs.perl6.org/language/concurrency?
02:19 Zoffix bpmedley, there's this presentation by jnthn++, but it's from before the remake of Supplies http://jnthn.net/papers/201​5-yapcasia-concurrency.pdf

02:19 bpmedley Yes, in addition to that.  I'm just doing as much reading as possible right now.

02:20 bpmedley I'll try reading for now, thanks.

02:34 autarch [Coke]: so updating rakudo didn't help - building the site still c. 2.5 hours and 3.6gb of memory :(
02:36 herby_ joined #perl6
02:36 llfourn autarch: is this related to pod?
02:37 autarch llfourn: yes
02:37 llfourn autarch: you are building docs using your new Pod::To::HTML?
02:37 autarch llfourn: yes, and it seems to be very slow and memory hungry
02:38 llfourn autarch: normally it takes like 10 mins or so and takes 700mb for me
02:39 autarch yeah, obviously this is much worse
02:39 autarch I really don't know why though, the new Pod::To::HTML code isn't doing anything crazy, AFAICT
02:39 * llfourn goes to take a look
02:40 autarch I'd appreciate the help
02:41 autarch I guess the other option is to go work on the profiler ;)
02:41 autarch since I can't profile this very effectively right now
02:41 geck so.. did perl6 do anything to improve pod or provide a better documentation mechanism?
02:41 llfourn autarch: The POD parser in the compiler is not great either https://rt.perl.org/Public/​Bug/Display.html?id=127020
02:42 Zoffix geck, I think so, but... I ironically the Pod stuff isn't well documented yet :P
02:46 geck so I'm seeing
02:46 llfourn and not well implemented :S
02:46 autarch llfourn: but clearly that isn't the problem here, I'm not doing any additional pod parsing
02:46 geck hrrm
02:46 Zoffix geck, I think you can actually examine POD from within your program even...
02:46 llfourn but great things are on their way for pod I think
02:46 llfourn autarch: yep :)
02:46 Zoffix I dunno, so far it sounds like my program is wasting precious cycles parsing POD when it should be running
02:46 llfourn Zoffix: with precomp it shouldn't matter
02:46 Zoffix fair point
02:46 Zoffix But still, the fact that documentation affects my program itself is a bit weird.
02:46 AlexDaniel geck: you can still write your comments in a very convenient way
02:46 llfourn to me is cool :)
02:46 Zoffix and the whole .WHY bit encourages spaghetti docs
02:46 geck AlexDaniel: tbh, I was hoping that something a bit more javadoc like would be in perl6
02:46 llfourn I like spagetti docs :D
02:46 geck or considered part of
02:46 AlexDaniel geck: there is! Let me find it…

02:47 llfourn with GH Markdown you can just do  [MyModule::Foo](MyModule/Foo) and it will link to the correct place
02:47 autarch though really, that's more the domain of the parser - [...](module:Foo::Bar] - let the parser sort it out
02:47 llfourn Foo.pm*
02:47 b4284 autarch: like with `with {}' blocks ?
02:48 Zoffix llfourn, how would it know where the "correct place" is?
02:48 autarch b4284: I'm not followed you - the Int:D $foo means that $foo must be an integer type value, and it must be defined
02:48 llfourn Zoffix: you're right lib/MyModule/Foo.pm
02:48 autarch it's possible to have an undefined Int value too
02:48 Zoffix llfourn, L<MyOther::Module/foo> is linking to another module not in the current repo
02:49 geck that sounds very fixable

02:50 b4284 autarch: wow, great, thank you
02:50 Zoffix llfourn, doubt it, as it'll surely involve specifying the username and the name of the repo that is not necessarily the name of the module itself
02:50 b4284 would it be the same with `my Int $val';

02:51 b4284 autarch: thanks for helping out
02:51 autarch you're welcome
02:51 AlexDaniel geck: basically #| and #= :)
02:52 Zoffix llfourn, no, I leave it to the parser to figure out where MyOtherModule is located. In fact, I think GitHub rightnow links to MetaCPAN
02:52 llfourn #| and #= are pretty flimsy though as I am just finding out
02:52 b4284 looks like the intro is not enough for me now
02:53 llfourn Zoffix: ah I see.
02:53 b4284 are there other postfix decorators like :D ?
02:53 Zoffix b4284, :U
02:53 Zoffix :D (defined) :U (undefined)

03:06 bpmedley My bad
03:06 konobi I'm just saying that the "new user" story is really bad
03:07 konobi it's all under TPF though, right?
03:08 Zoffix konobi, I'd think the new users would be using Rakudo Star, which hasn't been released yet
03:08 Zoffix And the install instructions were written in a rush during holidays (in fact, I was passed out drunk when release happened).
03:08 Zoffix It's just a really bad idea to release on Christmas and there was a shortage of hands.

06:06 Hotkeys is there a way to actually access values in one of these?
06:07 Hotkeys and by access I mean set mutably
06:07 geekosaur uvtc: adverbs and colonpairs are related. colon method syntax is not. (note however that :a<4> makes ('a' => '4'); in perl6, => is not just a fat comma, it is the constructor for a pair, which is a distinct type)

06:09 uvtc geekosaur, thanks! I don't yet know about colon method syntax, but how are adverbs and colon pairs related?
06:10 TimToady the only place we confuse the notations is in a smartmatch, where a pair is interpreted as a method call tests
06:10 TimToady (intentionally confuse, I should say)
06:10 mempko joined #perl6
06:10 TimToady it lets you stack boolean methods (such as on a filehandle) using junctions that way
06:11 geekosaur uvtc: colonpairs can be used to pass named arguments; adverbs are, as I understand it, just named arguments to things like operators
06:11 TimToady we tend to use "colonpair" to describe the notation, and "adverb" to describe the semantics use of the notation
06:11 TimToady *tic
06:11 geekosaur yes, that
06:12 [particle]1 joined #perl6
06:12 * geekosaur should not still be up but body is playing up; was trying to phrase that...
06:13 uvtc Thank you. Could you please point me to an example of how adverbs are used in connection with subs/functions? (Ex. do I pass a function an adverb? Do I declare a sub to take an adverb? Looking around the docs at http://doc.perl6.org ...)
06:14 TimToady as far as the function is concerned, they're just named arguments
06:15 TimToady it's just the syntax for the call gets a little fancier when you're applying an adverb to an operator rather than a normal function call
06:16 TimToady but the call '1 + 2 :foo' is really just the same as infix:<+>(1,2,:foo)
06:18 uvtc TimToady:  typo? `1 + 2 + :foo` ?
06:19 geekosaur no. in '1 + 2 :foo', :foo is applied to + not to 2
06:20 geekosaur 2 is not a thing that can be adverbed. another operator could , or a function could (in the latter case it'd be inside the call parens)
06:20 uvtc I see that `:foo` yields / evaluates to `foo => True`. ... I know in english an adverb modifies a verb... An adverb in Perl 6 is applied to a function?
06:20 geekosaur yes

06:20 geekosaur functions and operators being the verbs of perl 6
06:21 uvtc Can you give me an example of adverbing a function/sub? Do I create my own adverbs to apply?
06:21 geekosaur although there are other verbs as well; for example, if you index into an array or hash ([] or {}/<>/<<>> suffixes), the suffixes are also verbs and can take adverbs
06:21 geekosaur like, for example, :exists on hash lookups
06:22 aindilis joined #perl6
06:22 uvtc Yes. I don't get why it's `%h<foo>:exists` rather than `%h<foo>.exists`.
06:22 geekosaur an adverb is just a named parameter
06:23 geekosaur because . would apply too late
06:23 geekosaur the lookup would already have happened and it would be made to exist, with an "undefined" value if it didn't exist before
06:23 geekosaur but the adverb modifies the lookup itself
06:24 uvtc Oh. So I'm passing `exists => True` to the hash lookup post-circumfix op? That is, in addition to passing what's in the <>'s?
06:24 geekosaur the <> there, the compiler rewrites <foo> to {'foo'} and then calls postcircumfix:<[ ]>(key) (and adds :exists as a parameter if you specified that)
06:25 xpen joined #perl6
06:25 ugexe definitely no ambiguity now
06:25 TimToady :)
06:26 TimToady and it's still officially 6.c, according to the spec tests :)
06:26 geekosaur and the declaration for that is something like:  sub postcircumfix:<{ }>(::keytype $key, :exists = False)
06:26 geekosaur (where ::keytype is the type of the key in this hash; it's not really a sub but a method, I miswrote that)
06:26 TimToady actually, it is a sub
06:26 geekosaur (also wrote [] instead of {} e first time through)
06:26 TimToady used to be a method
06:26 geekosaur ah
06:27 geekosaur and that :exists should be :$exists
06:27 TimToady but subs can be optimized better at compile time
06:27 geekosaur so the body can test $exists to see if you specified that named parameter / adverb
06:28 TimToady which will become really important for indexing native multi-dim arrays
06:28 geekosaur in your own functions you can also use that :$name syntax to declare a named parameter, which then functions as an adverb
06:28 uvtc Ok. Ok, thanks. It looks like using an adverb is a way to pass an extra named arg to an opp that doesn't usually take an extra arg.
06:29 uvtc Right, and if it's one of my own regular subs, I can just use that :$name syntax, as you just said.
06:29 Averna joined #perl6
06:30 geekosaur yes, and you can use it to modify behavior without having to have a bunch of extra parameters (which is better: foo(1, :do-this, :and-do-that) or foo(1, False, True)?)
06:31 * geekosaur sees a lot of the latter in a C++ project he helps out with, and it's annoying to have to hunt down the prototype to see what it means...

07:56 Hotkeys Can I store a reference to a value in a hash value in another hash value eg
07:56 Hotkeys %foo{'a'} = %foo{'b'} * 2
07:56 TimToady all values are references, unless they're native
07:56 ChoHag Hmm.
07:56 Hotkeys and even if I change %foo{'b'}
07:56 Hotkeys %foo{'a'} will reflect that
07:56 TimToady you could use binding if you want that
07:57 ChoHag Well 'what-exactly-undefined-means' issues aside, what I actually have is 4 when clauses against variables (when $foo, when $bar, etc.), where 2 of them variables may be invalid matches under certain circumstances.
07:57 Hotkeys how could I do that?
07:57 Hotkeys with binding
07:58 TimToady use := instead of =
07:58 ChoHag Apparently undefining $foo didn't cause $foo to not match but to match, which was somewhat off.
07:58 ChoHag odd
07:58 ChoHag And off.
07:58 TimToady you told it to revert to its default value, and the default value is 'Any', which matches most things
07:59 TimToady smartmatching can't always read your intent
08:00 TimToady because people intend contradictory things
08:00 Woodi I tried @a = Any; to undefine @ but it ended with @a having Any as first element...

08:00 Hotkeys I don't think I'm doing this right

08:13 Woodi --prefix
08:13 mojca Woodi, if that was for me, I have --prefix=/opt/local
08:14 mojca the problem is that the binary is not yet in /opt/local during the build of rakudo
08:14 cpage joined #perl6
08:14 Woodi mojca: at least when i put moar in /opt nqp and raqudo don't know how to use $path...
08:14 Woodi mojca: you need to have moar first :)
08:14 mojca I understand, but I thought that rakudo would build it automatically
08:15 mojca and it does build it, it's just that moar is not yet in $prefix
08:15 mojca Should I build moar as a separate package?
08:15 mojca and put moar as a dependency rather than building it as part of rakudo?
08:15 Woodi mojca: it's strange, maybe --gen-moar don't work with prefix...
08:16 Woodi mojca: thing is that ppls use that auto-building for development purposes
08:16 mojca quick question: what exactly is the difference between rakudo and rakudo-star?
08:16 Woodi r* have additional modules
08:16 mojca which one should I package (one of them fetches things on the fly which I don't particularly like)
08:17 Woodi mojca: distro-packagers would probably like separate packages
08:17 mojca so auto-building of moar is there just for convenience and a package should not bother about it but rather install it separately?
08:17 Woodi mojca: in my opinion :)
08:17 Woodi but I'm not a developer :)
08:17 mojca ok, so I'll try to create a package for moarvm first
08:18 mojca nevertheless, should I bother about getting the installation problem fixed?
08:18 mojca and if so, what is the best place (I don't know enough about internals to be able to provide a perfect description for the bug report)

08:21 ChoHag I intend to fix this in the next week or so.
08:21 Woodi mojca: you install moar, then nqp and then rakudo. you can unpack rakudo, check in tools/build/NQP_REV which one nqp you need then unpack nqp, check tools/build/MOAR_REV which one moar you need :)

08:23 nine mojca: that message should just be the result of the check if we actually need to build moar and nqp.
08:23 mojca I can ignore the message, but it doesn't build.

08:24 nine Ok that sounds more serious
08:25 nine mojca: then I'd go with the recommendation to build the components separately. From a distro perspective, you will want separate packages anyway, won't you?
08:26 mojca Maybe. I don't know how exactly moar is used anyway. If it's just for perl6, it could be bundled together, but I agree that it's probably better to package it separately.
08:27 mojca I've seen that HomeBrew packages it together
08:27 mojca unless I was mistaken ... I don't know why they don't run into problems though
08:27 nine Well it was built for Perl 6 and the only known user is Perl 6. In theory it could be used for another language though.
08:27 ChoHag perl6 can run against the jvm (and there were other backends in the past). While perl6-moar could come with moar where perl6-java doesn't come with a jvm, for clarity it seems to me it'd make moar sense (heh) to have a moar package.
08:28 ChoHag s/doesn't/shouldn't/
08:29 lnrdo_ joined #perl6
08:30 nine Oh, that's certainly a valid perspective: while moar may have only rakudo as user, rakudo doesn't actually need moar, so it should be optional, hence a separate package.

08:37 Woodi anyway installing Win10 was final proof that internet white-listing is way to go :)  schools do this, Chinese too so users probably should too

08:45 Guest73034 Hi!
08:45 Guest73034 So, cool to see a room with so many people interested in Perl
08:45 mojca Just curious, when I was building rakudo, moarvm built successfully. Now I see that it keeps failing due to a number of missing libraries like libuv, dynload, ...
08:46 mojca I will add those libraries, I was just wondering why the difference in the default builds
08:46 azawawi joined #perl6
08:46 azawawi hi
08:46 yoleaux 13 Dec 2015 22:44Z <RabidGravy> azawawi: would you be cool with a PR to File::Which to make it optionally export 'whence' instead of which?  It's an ancieunte SysV user thing ;-)
08:46 Amnez777 joined #perl6
08:47 mojca Where does dynload.h come from?
08:47 azawawi Merry Christmas to #perl6 :)
08:47 Guest73034 I'm in a but of a conundrum
08:48 Guest73034 I can't decide between nodejs or perl for re-writing my personal website
08:48 Guest73034 I've got experience with both
08:48 Guest73034 node is convenient because it can send javascript objects using that neat, convenient library 'socket.io'
08:49 Guest73034 perl is awesome because of its best regex support, the $_ variable, and how it allows me to type action then condition
08:49 Guest73034 and just like the http module for node, perl now has perldancer, which is easy as pie to work with
08:50 Guest73034 but with perl6 coming out I'm trying to come up with a reason to use perl + perldancer
08:51 Guest73034 since I think perl6 is going to blow ecmascript6 out of the water in terms of expressability and power
08:51 nash_ joined #perl6
08:58 nine mojca: ./nqp/MoarVM/3rdparty/dyncall/dynload/dynload.h
08:59 pmurias joined #perl6
08:59 mojca ok, but isn't moarvm a dependency of nqp? So how do I get nqp's files while building moarvm?
08:59 nine Guest73034: well it's no easy decision. Perl 6 is the better language, hands down. It's not even a competition. It's also very new, so with node you'll just build that website and be done. With Perl 6 you'll spend quite some time on writing libraries or getting into Inline::Perl5.
08:59 mojca I'm running into an error while building moarvm.
09:00 nine Guest73034: with Perl 5 you'll get Dancer, but also have a harder Perl to learn :)
09:00 mojca I can somehow circumvent the problem by providing --has-libffi and by adding -I${prefix}/lib/libffi-3.2.1/include to CFLAGS
09:00 pierre-vigier joined #perl6
09:01 Guest73034 Wait - Are you saying dancer2 won't work with perl6?
09:01 mojca and even if I configure with  --no-jit, I get this error: src/jit/compile.c:2:10: fatal error: 'dasm_proto.h' file not found
09:02 ChoHag What's the opposite of recursive?
09:03 ChoHag mojca: What system?
09:03 mojca x86_64-darwin (OK, an old one, 10.7)
09:04 ChoHag Darwin. Of course. The one that'll be a PITA to run a test VM of.
09:04 andreoss joined #perl6
09:04 mojca Does that mean that Darwin is not fully supported yet?
09:05 ChoHag I don't think there's a 'supported' umbrella for anything to even fall under.
09:05 Axord joined #perl6
09:06 ChoHag And I don't think any/many of the devs use OSX.
09:06 Woodi mojca: it's strange. those libraries are included in tarbal. and there are Configure switches if you want your own
09:06 mojca Which tarball? MoarVM's?
09:07 Woodi mojca: yes, moarvm. but if you use git then they should be included too
09:07 ChoHag If you use git you may need to update the submodules to get them.
09:07 mojca I'm using 2015.12
09:07 ChoHag git submodule update --init in src's root.
09:07 mojca the tarballs from github
09:07 Woodi ok, I was not sure about git :)
09:07 ChoHag ... _after_ git checkout/pull/whatever.
09:08 luiz_lha joined #perl6
09:08 mojca should I fetch the tarball from somewhere else?
09:08 mojca I'll check
09:08 RabidGravy joined #perl6
09:09 mojca ok, I see now
09:09 mojca the tarball I fetched from github is only 1,7M
09:09 ChoHag dynasm, dyncall, libuv and linenoise in $src/3rdparty should not be empty. If they are, the tarball lacks them and they need to be obtained somehow. If you have a $src/.git you can probably get then with the afformentioned submodule command.
09:09 mojca The one in the link is 3,1M
09:10 mojca these folders are indeed empty
09:11 mojca I fetched https://github.com/MoarVM/Mo​arVM/archive/2015.12.tar.gz
09:11 mojca and that was most likely the problem
09:11 ChoHag Apparently osx works in kvm.
09:11 ChoHag FSVO work.
09:12 Woodi mojca: I got moar from it's web page and it was fully functional :)
09:12 mojca I'll switch the source of downloads
09:12 mojca Using GitHub is very handy, but useless if it fails to work
09:13 mojca :)
09:14 Woodi mojca: few days ago was big release day so for some time official release tarbals are best thing, IMO :)
09:17 rindolf joined #perl6
09:18 keenan joined #perl6
09:18 andreoss should `rakudobrew build moar коледа` work properly?
09:19 mojca perfect, it almost works now; it stops with 3rdparty/libuv/src/unix/getaddrinfo.c:102:68: error: no member named 'res' in 'struct uv_getaddrinfo_s', but that's progress
09:19 andreoss for me it dies with 'Unhandled exception: Will not decode invalid ASCII (code point > 127 found)'
09:19 RabidGravy andreoss the probably not
09:20 mojca (libuv itself can be installed without a problem)
09:20 dotness joined #perl6
09:20 nine Guest73034: you probably can combine Dancer2 with Perl 6. But that's experimental high tech territory. Note that Perl 5 and Perl 6 are really different languages. Bridging technology exists, but hasn't seen that much real world code yet: http://niner.name/talks/Building%​20Bridges/Building%20Bridges.pdf
09:22 AlexDaniel ChoHag: hmmm there's 「lazy」 but I'm not sure what is it supposed to do (is it even implemented?)
09:22 andreoss RabidGravy: seems like moarvm issue
09:22 Guest73034 I figure perl6 would have backwards compatibility
09:24 nine ChoHag: the opposite of "recursive" in programming is usually "iterative"
09:24 ChoHag I'd say that's alternative, not opposite.
09:25 ChoHag At least outside of programming, which is what I meant.
09:25 nine Remind me, why again we forcefully push people in rakudobrew's direction, when it's causing so many problems while building rakudo is just perl Configure.pl --gen-moar && make install
09:25 ChoHag Recursively in a 'searching through a tree' sense.
09:25 ChoHag nine: Because it has bells and whistles.
09:26 RabidGravy nine, beats me
09:26 ChoHag Also, it's never "just".
09:26 ChoHag That wouldn't have worked for mojca, for example.
09:27 nine To top it off it's barely maintained at all! So the first contact users have with rakudo is with a build tool that's barely maintained and known to cause all sorts of strange problems.
09:27 ChoHag Admittedly because one of the 3rd party libs doesn't seem to build on OSX, but still...
09:27 AlexDaniel ChoHag: so in DWIM fashion that would be something like 「sub foo { say ‘world’; return 42 }; my $x := lazy { foo }; say ‘hello’; say $x」, but it does not work
09:28 mojca which library doesn't build on OS X?
09:28 ChoHag Having not paid much attention to the public side of the announcement, where exactly are new folks directed to perl 6?
09:28 mojca (just out of curiosity)
09:28 pierre-vigier joined #perl6
09:28 nine ChoHag: mojca is hardly a normal user. He tries to build packages for distribution. Normal first time users really just need what I wrote above.
09:28 ChoHag mojca: libuv, apparently.
09:28 andreoss RabidGravy: should i report it?
09:28 mojca oh, no, libuv builds just fine
09:28 ChoHag nine: Experience teaches me that there's no such thing as a normal user, even outside of development circles.
09:28 mojca I figured out what the build problem was
09:28 Guest73034 Well personally as a new folk, I found my way thanks to some forum post. Watched a few youtube videos, was amazed.
09:29 keenan joined #perl6
09:29 mojca I was initially trying to build from github that was missing some 3rdparty libraries, including libuv
09:29 mojca so I installed (an outdated) libuv from the package manage
09:29 ChoHag You pasted an error above of it failing to build. I jumped to a conclusion.
09:29 mojca *manager
09:30 RabidGravy andreoss, against "rakudobrew" possibly, it's not a moarvm issue as far as I can tell
09:30 mojca and then the build issue arised because the compiled used outdated headers from $prefix rather than headers from 3rdpart
09:30 nine ChoHag: http://rakudo.org/how-to-get-rakudo/ "Building from source", http://perl6.org/downloads/
09:31 andreoss it dies on compiling moarvm code
09:34 RabidGravy right, but it is almost certainly being given garbled up utf-8 by rakudobrew
09:35 andreoss but checkout from git works well
09:37 RabidGravy yes
09:38 mojca I believe there is a bug in build scripts that put ${prefix}/include before the includes from 3rdparty in CFLAGS, but I eventually managed to compile MoarVM
09:39 mojca the main problem now is that it wants to install a number of libraries that don't belong there
09:39 pierre-vigier joined #perl6
09:39 mojca for example, MoarVM now wants to install ${prefix}/include/libuv/uv.h
09:39 mojca which it shouldn't
09:40 ChoHag Can I specify a Signature in which extra named parameters are not welcome?
09:40 RabidGravy I'm not sure, doesn't nqp need to know about some parts of uv?
09:40 ChoHag Alternatively how can I construct a collection of multis which have 2 or more optional adverbs?
09:41 RabidGravy ChoHag, it is possible (the former) but a but of a mouthful
09:42 RabidGravy m: sub foo(:$foo!, *%b where *.keys == 0) {}; foo(:foo, :bar)
09:42 camelia rakudo-moar 373adc: OUTPUT«Constraint type check failed for parameter '%b'␤  in sub foo at /tmp/lI6uuivpfY line 1␤  in block <unit> at /tmp/lI6uuivpfY line 1␤␤»
09:43 RabidGravy bit of a mouthful that is
09:43 ChoHag Don't like the look of that.
09:44 RabidGravy there has to be a slurpy hash as there is a default slurpy that you get if don't specify it and that will get any other nameds
09:45 RabidGravy you could probably make a sub or method trait that did it for you
09:46 Guest73034 I wonder what my little program in Javascript: http://pastebin.com/KAbJxniu would look like written in Perl? I'll have to get to it!

09:55 nowan joined #perl6
09:56 znpy joined #perl6
09:56 ChoHag Dependency tracking is a hairy problem.
09:57 ChoHag I expect including those 3rd party libraries was a solution deemed good enough for development time.
09:58 ChoHag Now that it's reached 'production' (FSVO) they need a bit more nuance.
09:58 RabidGravy I know of things that have been around for years that bundle some of their dependencies, usually because there is so much variance in version in the wild
09:59 ChoHag Including dependencies is fine. Building them and installing them without consideration of the external environment less so.
10:00 RabidGravy yeah, should go in a private place
10:00 lnrdo joined #perl6
10:00 ChoHag foo():bar:baz just calls foo(:bar, :baz) right?
10:01 lnrdo joined #perl6
10:02 ChoHag So what does foo():bar:baz($bing) do?
10:04 RabidGravy in the former case you get booleans, in the latter baz haz the value of $bing and bar is still a boolean
10:05 ChoHag Not that.
10:05 nine After reading many posts on hacker news of all sites it's really depressing to see so much negativity on lwn.net.
10:06 ChoHag It doesn't appear to call foo(:bar, :baz($bing)).
10:06 ChoHag nine: Welcome to the internet.
10:07 nine ChoHag: lwn.net used to be a shining safe haven with comments that really add to the site's content.
10:07 RabidGravy ChoHag, no really it does
10:07 RabidGravy m: sub foo(*%foo) {say %foo}; foo():foo:bar("ghshs")
10:07 camelia rakudo-moar 373adc: OUTPUT«bar => ghshs, foo => True␤»

10:25 RabidGravy FritzZaucker, for one thing it predates NativeCall being in core so that part is un-necessary
10:26 RabidGravy andreoss, that doesn't mean it's Moars fault, it just means that "something" is putting a badly encoded string somewhere it shouldn't
10:27 FritzZaucker joined #perl6
10:29 andreoss RabidGravy: i run moar directly from shell, what else could it be?
10:30 RabidGravy how did the moar get built?

10:31 dalek mu: review: https://github.com/perl6/mu/commit/6eec18fed4
10:33 RabidGravy I would contend then that "something" while configuring moar caused a poorly encoded string to get into the compiled moar, so my first suspect in this case would be rakudobrew, my second suspect would be moar's configure
10:33 moritz_ .tell Ulti re http://irclog.perlgeek.de/p​erl6/2015-12-26#i_11782724 please ping in 2016 about that, currently not at home

10:35 moritz_ thanks everybody, and most of all [Coke]++, for the great release
10:36 * moritz_ disappears into the bottomless void of mobile-only Internet again
10:36 andreoss also, why moarvm uses Windows-style path separator?
10:36 andreoss in its trace stack
10:38 nine andreoss: it usually doesn't?
10:39 andreoss may be i haven't noticed before
10:40 andreoss nine: is it a default? why?

10:41 lizmat pmurias o/
10:41 RabidGravy FritzZaucker, it appears that if you change the schedule_on to schedule-on and use the GTK::Simple from the ecosystem it dies in an altogether more interesting way
10:42 lizmat pmurias: I understand you have a grant proposal?   do you have a url handy ?

10:44 nine andreoss: the gen\moar\stage2\NQPHLL.nqp is what the source code claims for a file name
10:48 diakopter nqp is usually bootstrapped on a windows machine
10:48 diakopter re-bootstrapped
10:49 diakopter there's a version of nqp in its repo (called stage0) that is built from the last successfully bootstrapped one. it was originally bootstrapped from a port of pmichaud's original nqp compiler/regex engine for parrot

10:55 andreoss nine: it looks bad
10:55 skyl4rk joined #perl6
10:57 cygx andreoss: you understand how bootstrapping works?
10:57 nine andreoss: you will see this only when NQP's build fails. Once NQP is built, it will show paths according to your platform's conventions.
10:57 cygx packaging an nqp build for both *nix, windows, $whatever just to make it look better is not a good idea
10:57 andreoss cygx: probably not, but i guess you need a existing nqp to build a new one
10:58 diakopter andreoss: but yes, there is a bug there preventing using that коледа tag

11:02 cygx there might a discussion to be had if some conventions should be checked at run-time instead of compile-time if we wanted to distribute .moarvm files

11:10 lizmat these results seem inconsistent to me
11:11 lizmat if we take the same logic as we have with leap-days, then :1day result should be the same as the :86400second result
11:16 lizmat .tell masak is there a reason why DateTime.new(1972,12,31,23,5​9,60,0).later(:86400second) and DateTime.new(1972,12,31,23,59,60,0).later(:1day) should give different results ?
11:16 yoleaux lizmat: I'll pass your message to masak.
11:21 timotimo oh my word, the backlog is gigantic
11:21 cygx lizmat: depends on whether you define a day as a (variable-length) calendar day, or a constant unit of time
11:23 cygx tough the former doesn't really make sense if yo use the day as a duration
11:23 xinming joined #perl6
11:24 cygx I guess what it comes down to is whether

11:25 mojca Is it OK to fetch NQP from https://github.com/perl6/n​qp/archive/2015.12.tar.gz or are there any caveats like for MoarVM as well?
11:26 nine timotimo: yes, the usual slow down during European night is far less visible now
11:26 timotimo ugh :)
11:27 nowan joined #perl6
11:28 ShimmerFairy considering we already take a day to be 24 hours in this case, I'd lean towards the more human-friendly choice :)
11:28 crux joined #perl6
11:29 lizmat cygx: so would you consider the current result correct or incorrect ?
11:29 cygx mojca: I think it's fine, but the 'supported' ways to get the source via `git clone` or from http://moarvm.com/releases.html and http://rakudo.org/downloads/
11:30 lizmat I mean, if we go from 2016-01-31 + 1 month, we wind up in 2016-02-29
11:30 lizmat aka, we don't carry over to the next month
11:30 lizmat this is even documented in the code:
11:30 lizmat # If we overflow on days in the month, rather than throw an
11:30 lizmat # exception, we just clip to the last of the month
11:31 ShimmerFairy lizmat: I think I'd expect it to be the same as :86400seconds , since that will be "tomorrow, at this same time" according to human eyes :)
11:31 cygx ShimmerFairy: not if there's a leap second
11:33 ShimmerFairy cygx: technically, yes, but a human would see the clock and say that 1973 Jan 1 23:59:59 is exactly one day since 1972 Dec 31 23:59:59
11:34 cygx ShimmerFairy: but then :1day !== :8400seconds, and your comment no longer makes sense ;)
11:34 ShimmerFairy oh wait, I was misreading the tests.
11:35 ShimmerFairy lizmat: is there any case where we can really expect someone to try 60 as a number of seconds and then get upset that :1day and :86400seconds aren't the same?
11:36 cygx lizmat: I guess same time next day would be more DWIM-y

11:37 sno joined #perl6
11:37 lizmat so I was asking masak what his thinking was when implementing this
11:38 lizmat as this behaviour seems to be different from the behaviour seen when moving 1 month from a day that doesn't exist in the next month
11:39 ShimmerFairy lizmat: my feeling is that :second is a precise statement of how many seconds you want to advance, while :day will read as "give me the next day", a less precise measure to be asking for.

11:39 ShimmerFairy lizmat: so, my feeling on :day is the same as it was on :month; when I say the next month of Jan 31, I'm really expecting February, not March :)
11:40 lizmat right, so you agree with my point  :)
11:40 lizmat m: say DateTime.new(1972,12,31,23,59,60,0).later(:1day)   # should be on Jan 1

11:41 ShimmerFairy lizmat: yes, because I at least mean the next square on the calendar when I say "1 day later", not a precise accounting for leap seconds and such :)
11:43 ChoHag Maths on dates?
11:43 ChoHag Hold on. Need popcorn.
11:44 ChoHag OK continue.
11:46 cygx personally, I only measure time in beats of (86400/1024)s since Unix epoch
11:46 cygx who cares about such h´things as 'minutes', 'hours' or 'days' :p
11:47 mojca What's the proper way to check the output of tests and the proper place to report failures?
11:48 mojca I get t/hll/06-sprintf.t .................... Failed 7/265 subtests
11:48 mojca t/nqp/60-bigint.t ..................... Failed 1/80 subtests
11:51 ChoHag minutes and hours are arbitrary but the day and year are perfectly cromulent units of measure.
11:51 ChoHag And, incidentally, why decimal time measurement is a ridiculously stupid idea.
11:51 cygx mojca: moarvm an nqp bugs are tracked on github, for rakudo proper, send an email to rakudobug@perl.org with a subject starting in [BUG]
11:52 cygx you can run test files manually (./nqp

11:52 llfourn mojca: usually with --fudge --moar as well
11:52 cygx ChoHag: my atomic clock has no setting for 'days' or 'years'
11:53 ChoHag Well that's a shame because the planet you live on does, and they're hard-coded.
11:53 mojca nqp doesn't accept --fudge or --moar
11:54 mojca I get not ok 39 - mod_I - positive and negative
11:54 llfourn mojca: sorry I thought you were talking about rakudo :)
11:54 mojca but I'll try perl5
11:58 mojca anyway, nqp::mod_I(box(12), box(-4), $bi_type) from that test suite returns -4
11:58 mojca I guess I should report that to the nqp bug tracker then?

12:30 nine Oh, a fix for that issue is in nom
12:32 CIAvash joined #perl6

12:32 lnrdo joined #perl6

12:35 mojca is nom just a "synonym" for "master/trunk"?
12:35 mojca I'll try to use that one then
12:35 lizmat mojca: yes
12:35 mojca I'll double-check the libraries being used
12:35 lizmat hysterical raisins
12:36 lizmat it stands for "new object model"   (which was once new)
12:36 mojca I need to figure out what to do about the libraries though because it will be a bit annoying to have perl6 conflict with a number of other ports
12:36 vendethiel .oO( we still think it's cute )
12:36 mojca ports = packages
12:37 jdv79 ugexe: yeah.  i've just started looking into this stuff.  might be a while til i get anything useful done as i'll be traveling more in the next few weeks.
12:37 mojca would it be acceptable to use perl6 with external libraries if I make sure that all external libraries are really up-to-date?
12:37 mojca that is: as the long-term goal
12:37 jdv79 ugexe: maybe someone else could pitch in:)  but if not i'll hit it when i get back.
12:37 mojca for testing it's fine if I use the internal ones
12:38 RabidGravy mojca, if it can be made to work then I am sure the input would be much appreciated :)
12:38 mojca Or this one would have to be addressed: https://github.com/MoarVM/MoarVM/issues/321
12:38 kid51 joined #perl6
12:45 nine mojca: please note that AFAIK MoarVM uses a somewhat outdated version of libuv currently. It needs to be updated at some point. I guess it's very much dependent on libuv's stability (as in API) track record if we can use external libraries
12:47 RabidGravy mojca, fwiw there's a #moarvm channel where there may be less noise to discuss these matters :)
12:47 mojca thank you
12:48 RabidGravy but I think there would probably be broad agreement with what you are suggested
12:48 RabidGravy er suggesting
12:50 timotimo lizmat: "nom regression" :)
12:52 cosimo hi folks!
12:52 timotimo hey cosimo
12:52 cosimo (my first message of the post-Christmas era) :-)
12:53 RabidGravy yo!
12:53 cosimo any comments on such issues? https://github.com/cosimo/​perl6-digest-md5/issues/15
12:53 cosimo why should I or shouldn't I change the code to kebab-case?
12:54 saaki joined #perl6
12:55 RabidGravy well, the expectation set by the Perl 6 core API is for kebab-case rather than snake_case but it's probably a matter of taste in modules
12:55 nash_ joined #perl6
12:55 RabidGravy I'd go with add kebab-case, deprecate the camel_case and remove them some point in the future to minimise the fallout
12:56 cosimo specifically for modules that are transposed from p5, I would expect the same names
12:56 RabidGravy do both then
12:56 RabidGravy :)
12:56 cosimo is there some *md5-hex = *md5_hex kind of aliasing?
12:56 timotimo constant &md5-hex = &md5_hex
12:56 nine cosimo: I'd use camel_case for the P5 interface and if you add a more 6ish interface, use kebab-case for that
12:57 cosimo nine: yes. makes sense to me. In that case, I would drop Digest::MD5 entirely and have a Digest module (sort of python's hashlib)
12:58 cosimo thanks guys

13:13 cosimo stupid q. what's the difference between 'constant T = 42' and 'my \T = 42' ? what's 'my \T' anyway?
13:14 Skarsnik A sigil less variable
13:14 nine cosimo: \T is a sigilless variable, that's a variable that doesn't impose any interface at all on its contents (while e.g. an @array forces the contained object to do the Positional role)
13:15 Grrrr joined #perl6
13:15 nine cosimo: my $foo forces a Scalar container, i.e. something that can be assigned to.
13:16 cosimo next q is why would I need a sigilless variable?

13:26 timotimo no source code?
13:26 awwaiid nine: I like this terminology of sigils being Role restrictions
13:26 timotimo wtf.
13:26 awwaiid timotimo: Skarsnik: there is definitely source, lemme see...
13:26 RabidGravy Skarsnik, a binding to libpd or supercollider would work too, I've got one of those on my TODO but way way down
13:26 awwaiid https://github.com/samaaron/sonic-pi
13:27 RabidGravy aha, awwaiid++ just not obvious enough for me then ;-)
13:27 awwaiid I've read through the source -- it is from one of the authors of Overtone (clojure), and interestingly one of the first thing the author does in sonic-pi is to add some functional helpers to ruby
13:27 awwaiid RabidGravy: yeah -- the site is more for consumers than for developers
13:27 timotimo just watching the lightning talks from the 32c3 right now
13:28 timotimo of course the topics wildly differ
13:28 timotimo http://streaming.media.ccc.de/  -  there's also a switch at th ebottom between "native" and "translated"
13:28 timotimo so if the tack is german, you can get the synchronous translation instead
13:28 RabidGravy so supercollider binding then - shouldn't me much of an ask

13:34 Skarsnik I should try atom, how well it fair on not so new PC?
13:36 awwaiid Skarsnik: this 'atom' is a concurrency construct, not the editor
13:36 timotimo yeah, but i think he just got inspired
13:36 awwaiid ah :)
13:36 timotimo by the name alone
13:36 Skarsnik ? Oh I was lost watching if there was an update of my perl6 syntaxhightligh for Kate
13:37 RabidGravy jnthn's OO::Monitor does something similar I think
13:40 RabidGravy gah, HTTP::Server::Async has a bug in chunked decoding brought on by the \r\n thing
13:40 RabidGravy where is that guy who fixed up the chunked stuff for H::UA when you need him
13:41 awwaiid OO::Monitor looks like a superset of the functionality of atom's swap! ; in clojure (def foo (atom 5)) (swap! foo inc) does an optimistic increment of the contents of foo -- if some other thread modifies foo at the same time, the swap! will throw away its result and try again (over and over until it "wins"). so swap! takes an atom and a function, passing the function the current contents of the atom
13:41 vendethiel atom, agents, ref... clojure's STM is lovely
13:41 awwaiid yeah
13:41 awwaiid and very-built-in
13:43 awwaiid seems like one could build equivalent apis with clean syntax in p6
13:43 RabidGravy yeah all the bits are there I guess
13:44 awwaiid my Atom $foo = 5; $foo.swap(*++)

13:45 awwaiid Greetings garu

13:48 timotimo that's not a copy or clone operation
13:48 timotimo that.s just an assignment
13:48 awwaiid vendethiel: yeah, I see what you mean
13:49 awwaiid m: my Int $x = 2; my $y = "foo"; my Str $z = "bar"; $y = 2; $z = $x;

14:01 Skarsnik the harness on Test is really bad most of the time..

14:03 cosimo any possibility of readline support and/or tab completion?
14:04 Zoffix cosimo, there's Linenose
14:04 awwaiid cosimo: right now perl6 by itself is the main option. I'm building a toy named LREP (it provides perl6-lrep), but it has less features. someone is also working on a jupyter backend (aka iPython) which should be awesome

14:04 cosimo ah, cool
14:04 awwaiid cosimo: yes, if you 'panda install linenoise' then your perl6 built-in repl will be a lot more useable

14:08 ShimmerFairy loren: looks like the internal pointer (or whatever it is) doesn't update along with a change in the array's size or something. The solution of course is to not modify an array you're looping over :)
14:08 awwaiid loren: that's pretty interesting. I think the for loop maybe iterates over a copy or snapshot of @x?

14:16 ab6tract use while or until for that
14:17 Skarsnik mojca, I don't know, I was hoping running a test alone give some clue or why it fail
14:17 mojca as I said, it doesn't fail
14:17 mojca it just doesn't start

14:17 loren Zoffix, oh, For instance, i have a file content like this 'EN = A\n CN = \n EN=...'
14:17 mojca Dubious, test returned 1 (wstat 256, 0x100), No subtests run
14:17 _wiz_ does panda support DESTDIR?

14:18 loren Zoffix, when a read a EN line, i want read next line immediately
14:18 Zoffix loren, why? What are you trying to accomplish?
14:19 loren ab6tract, which loop control should i use ?
14:19 ab6tract loren: see my example above
14:19 _wiz_ zoffix: PREFIX is something else than DESTDIR, but good to know.
14:19 mojca Skarsnik: oh, I have found the way
14:19 loren Sorry, my example is in the company's computers

14:20 RabidGravy quick straw-poll is anyone seeing the problem https://rt.perl.org/Ticket/Update.html?id=126832 ?  H::UA doesn't do it and the easy reproduction doesn't
14:20 ab6tract loren: " $z %% 2;" this would be your test for EN line
14:20 mojca until it's asked to do so
14:21 mojca is there any remedy for that?
14:21 nine _wiz_: the files in share/perl6/short are quick lookup files that map from module name to distribution containing such a module.
14:21 Zoffix RabidGravy, that link sucks :)
14:21 Skarsnik RabidGravy, thta the update page x)
14:21 RabidGravy oh
14:21 nine mojca: does make test work _after_ a make install?
14:22 ab6tract loren: does this make more sense?
14:22 _mg_ joined #perl6
14:22 _wiz_ nine: thanks. are the hashes stable across operating system versions or operating systems?
14:22 RabidGravy https://rt.perl.org/Ticket/Display.html?id=126832 :-p
14:22 mojca what should a make install change?
14:22 mojca I already installed rakudo, yes
14:22 loren Wait a moment, i make a example
14:22 nine _wiz_: yes. It's just a sha1 of the module name
14:22 Zoffix ab6tract, that code is terrible :|
14:22 _wiz_ nine: good news! thank you.
14:22 ab6tract Zoffix: I'm getting a bit tired of your negativity tbh
14:22 Skarsnik nine, mkdir with 777 permission sucks x)
14:23 mojca nine: but the package manager doesn't let the package create a directory
14:23 ShimmerFairy Skarsnik: it will respect your umask, fwiw, it's just LTA that it doesn't factor that in :)
14:23 nine Skarsnik: that 0o777 is subject to your umask
14:23 mojca and I'm not sure where that is done
14:23 ShimmerFairy *that in to the message, that is
14:23 ab6tract some days it feels like every other line out of your irc client is trash talk
14:23 mojca because 53-transpose.t doesn't have any signs of creating directories
14:23 Zoffix Only some days? :)
14:23 ab6tract dude, it's not cute
14:23 Zoffix Wasn't trying to be
14:23 nine mojca: rakudo tries to create the directory when it's looking for a module
14:24 mojca scratching my head ...
14:24 mojca why?
14:24 nine mojca: that was just a shortcut I took and was never meant to be a permanent solution. It's just that the release came in between.
14:24 Zoffix RabidGravy, do I need to set NETWORK_TESTING and install IO::Socket::SSL to get the error?
14:24 Skarsnik RabidGravy, did you change UA so I can update?
14:24 mojca is there any way to disable that behaviour temporary, just to see if the tests pass?
14:25 loren ab6tract, actually i have other way to solve the parser problem, i take more attention to the behavior of 'for'.
14:25 mojca or is there much more that would go wrong?
14:25 dotness joined #perl6
14:25 RabidGravy Zoffix, no it just blows up as soon as it gets to the third test
14:25 Zoffix RabidGravy, I got successful install. Trying now with Pastebin::Gist that is also mentioned on that ticket
14:26 Zoffix ==> Successfully installed Pastebin::Gist
14:26 Zoffix Seems like it was fixed at some point
14:26 ab6tract loren: ack. the thing is that for is just not a good construct if you want to pop/shift an array.
14:26 RabidGravy Skarsnik, not quite yet but it only reverts the "no precompilation" which I put in when it all went on fire the other week
14:26 ab6tract Zoffix: please explain what is so horrible about my code example
14:26 * RabidGravy readies a pony drop
14:27 kaare_ joined #perl6
14:27 loren ab6tract, so i should use loop or while ?
14:28 cosimo Zoffix: hoelzro: Readline works nicely, thanks
14:28 ab6tract and provide an alternative way to conditionally pull a value from an array on the condition of a current value
14:28 Skarsnik Attribute should have a method to get the sigiless name of a attribute x)
14:28 ab6tract loren: i'm still a bit fuzzy on what you are trying to accomplish
14:29 loren ab6tract, ok, wait me a moment, i write a example
14:29 ab6tract but if you want to pull one element, inspect it, and conditionally pull another one in the same iteration, than what i've provided should do what you want
14:29 mojca nine: files under $prefix are owned by root, while package manager uses its own user and only allows certain actions to be done as root
14:30 leont joined #perl6
14:30 nine mojca: I'm testing a fix that ought to at least make make test work
14:30 talexb_ joined #perl6
14:31 mojca perfect, thank you
14:31 Zoffix ab6tract, because it's unreadable. And the real problem is this: "<ab6tract> loren: i'm still a bit fuzzy on what you are trying to accomplish". Which is why I asked loren to elaborate on the goal and not just on their current means of trying to achieve. I think programming is more than just writing a bunch of characters. But sorry you think it's tiring negativity on my part.
14:34 RabidGravy Skarsnik, I have now update H::UA and even bumped the version so you can just do "panda install ...." without it blowing up
14:34 RabidGravy :)
14:34 nine mojca: https://gist.github.com/niner/fb4979e3d5c90cd476e8
14:35 RabidGravy as a side benefit the tests seem to run quicker
14:35 Skarsnik and why it's a super slow :(
14:35 Skarsnik 30-cookies took forever
14:35 Skarsnik wtf
14:36 RabidGravy well previously there was "no precompilation" in Message, Request and Response
14:36 nine Skarsnik: does HTTP::UserAgent still carry the 'no precomplation;'?
14:36 RabidGravy no I just ridded it nine
14:36 Guest15478 joined #perl6
14:36 Skarsnik I am surprised nobody felt on a bug I left in cookies, but I feel like I was the only one using h:ua to login on a website xD
14:37 nine RabidGravy: that carries the risk of provoking run_alt again. But I guess it would actually be a good thing if we could reproduce it reliably again.
14:37 Skarsnik ==> Installing HTTP::UserAgent
14:37 Skarsnik HTTP::UserAgent:ver<1.1.10>​:auth<github:sergot>:api<> already installed
14:37 Skarsnik I hate this bug
14:37 AlexDaniel Skarsnik: --force it
14:37 AlexDaniel
14:37 timotimo --force? :P
14:37 Zoffix what's the bug?
14:37 RabidGravy eh? I upped there version
14:37 Skarsnik why it run the test all?
14:37 Zoffix Ah, right, I already asked last night.
14:38 nine Skarsnik: that's no bug.
14:38 Skarsnik I don't see how it's not a bug...
14:38 RabidGravy -    "version"   : "1.1.10",
14:38 RabidGravy +    "version"   : "1.1.11",
14:38 ab6tract m: my @a = 1..10; while +@a and @a.shift -> $x { if $x %% 2 and +@a { my $y = @a.shift; say "x:$x\ty:$y" } }
14:38 camelia rakudo-moar 373adc: OUTPUT«x:2  y:3␤x:4 y:5␤x:6 y:7␤x:8 y:9␤»
14:38 Zoffix LTA behaviour, I'd think: bail out of install if the version is already installed.
14:38 RabidGravy it's a bug somewhere if it hasn't used the right version
14:38 nine Skarsnik: you try to install an already installed version and rakudo refuses to do useless work. Where's a bug in that?
14:39 RabidGravy but I upped the version
14:39 RabidGravy it's 1.1.11 now
14:39 Skarsnik why trying bothering trying to install of it's already here..
14:39 nine RabidGravy: yep, that's more of a bug.
14:39 Skarsnik It should just say "It's already up to date"
14:39 awwaiid yeah. more like a warning than an error
14:39 nine Skarsnik: then implement just that
14:40 ab6tract Zoffix: ok man. it was unreadable. glad to know, because i did not notice. and yeah, it's the cumulation of reading you say things like "Failador" and "binning this with questionable design decisions"
14:40 Skarsnik It should not throw at least if it's an expected result x)
14:40 lustlife` can anyone tell me how to show camelia output normally in emacs irc buffer, do i need set some font for this ? the new line symbol show 2424, but in browser irc log,it shows normally with nl.
14:41 loren Zoffix, ab6tract , em, my english is so poor, haha ^_^, here the example https://gist.github.com/ih​ateme/6f3bb7c8683958c06c8b
14:41 Skarsnik RabidGravy, well all the test passed at least ^^
14:41 ab6tract loren: link 404s.
14:41 awwaiid loren: link says 404, maybe you accidentally made a private gist
14:41 RabidGravy as nine says it may go on fire again, but it's a canary if you will
14:42 _wiz_ are there MoarVM people here?
14:42 awwaiid lustlife`: what do you mean by camelia output?
14:42 Zoffix awwaiid, the robot
14:42 awwaiid ahh

14:43 timotimo With more WATs, more broken concepts, and more wildly popular 0-days, we will finally prove the Perl language is a broken concept, one that stood tall for way too many years.
14:44 loren ab6tract, But i am sure it's public ..

14:47 mojca thank you
14:47 mojca I guess that it only makes sense to do a simple "make test" or should I attempt other tests as well?
14:47 timotimo Skarsnik: you can add a role that records the order of key insertions and removes keys on deletion
14:47 timotimo and then uses nextsame to do the actual stuff the hash does
14:48 timotimo an implementation of that almost fits into a single IRC line
14:48 Skarsnik I want to handle DB field in a hash but I would want to have them always in the same order when going through it with kv x)
14:49 nine mojca: make spectest will download and run the spectest suite, but that's completely overblown for a simple installation
14:49 timotimo why not just .kv.sort(*.key) then?
14:49 Skarsnik Oh right
14:50 RabidGravy timotimo, was that guy scared by a Perl as kid or something?
14:50 mojca nine: ok. The question is whether this should be run at least once to confirm whether I missed something while preparing a package (users of the package would not run it)
14:51 mojca but if that is mainly for developers, I'll skip it as I don't plan to participate in the actual development
14:52 Zoffix timotimo, heh. wow, that's quite an event description. Funny, I'm pretty sure I know what the issue they're going to describe really is.
14:52 nine mojca: I'd say you already are :)
14:53 RabidGravy that's how it always starts ;-)
14:53 FritzZaucker https://github.com/vendethiel/moarvm-gcerr-gtk ... jnthn's golf-helper.p6 (with schedule-on() instead of schedule-off() with 6.c and current GTK::Simple give the same error: "Invalid GC status observed". Does that mean that this is not working at the moment?
14:54 vendethiel FritzZaucker: yeah, that's why I created this rpeo
14:54 vendethiel repo*
14:55 RabidGravy I have an instinct it's the NativeCall/schedule-on combo but no evidence to back it up
14:55 FritzZaucker Ok ... too bad, I was just trying to implement my first (useful) p6 program and that would need a GUI and a timer ... I guess I'll have to think about something else then.
14:57 cosimo wow, I had a different idea of ccc... https://www.youtube.com/watch?v=noQcWra6sbU

15:03 Zoffix loren, is the output always going to be EN/CN/EN/CN or do some lines contain EN/EN?
15:03 RabidGravy leont true
15:03 ab6tract loren: i think you want to try the variation i provide
15:03 ab6tract m: m: my @a = 1..10; while +@a and @a.shift -> $x { if $x %% 2 and +@a { my $y = @a.shift; say "x:$x\ty:$y" } }

15:05 Zoffix loren, then you can use for @lines -> $en, $cn. And you can use grep when you create @lines to filter out any unwanted crap
15:05 vendethiel lol, "we expect other languages to use the first element of the list" well no, I can prove that more languages even do like perl :D. but yeah, your talk sucks
15:05 Zoffix loren, gonna show you an example if my editor finally decides to start up -_-
15:05 loren ab6tract, thanks , check the element count is one way ..
15:06 ab6tract loren: as Zoffix mentions, if you know they come in EN/CN pairs, then pulling two at a time in a for loop is perfect
15:07 loren Zoffix, will it work on a large file ?
15:07 vendethiel "list is not a data type, they are just expressions" now you're just making up words :')

15:12 loren poldepaor, hi
15:12 Juerd timotimo: Are you at 32c3?
15:12 mojca I'm not sure about the best way to post long chunks of code
15:12 RabidGravy I think a Language/ page on "lists and arrays" is probably in order
15:12 nine mojca: what's the permissions of /path/to/rakudo/work/rakudo-373adc0/lib/.precomp?
15:12 Skarsnik vendethiel, I don't even want to watch more of his talk, I guess it's like "Oh look there is no type on the language, so no data check, ohoho"
15:12 RabidGravy mojca, most people use github gists but ymmv
15:13 Zoffix Ugh, Sublime Text 2--
15:13 Zoffix loren, um, probably. I'm not sure if grep returns a lazy list in Perl 6. You could try it out: https://gist.github.com/zoff​ixznet/3c563a64d5c760983d85
15:13 vendethiel Skarsnik: nah, I mean, the issue is real. I consider wantarray a bug, and the API "param returns a scalar or a list" to be awful. But everything else is stupid
15:14 mojca nine: lib/.precomp is drwxr-xr-x (755)
15:14 nine param is very much deprecated by now due to this issue
15:14 Zoffix I have tons of code with scalar or list APIs.
15:14 nine mojca: and it's owned by the user running the tests?
15:14 mojca yes
15:14 ab6tract grep returns Seq which is lazy
15:14 Zoffix Sweet
15:15 leont Yes, it is awful, but as a community we've been telling people that for a decade.
15:15 nine mojca: does .precomp/.lock exist and have the same owner/permissions?
15:15 leont In particular, we've been telling them not to use CGI.pm
15:15 Juerd leont: Unfortunately, "we" do tell people to use drop-in replacements for it...
15:15 mojca .precomp/.lock exists and has permissions 644
15:16 mojca but it's true that one test suite is still running and I ran the failed test separately if that makes any difference
15:16 Juerd But yeah, the problem identified in that talk is not new and not very interesting.
15:16 poldepaor Any links to any good documentation and programs to get started with perl6? Looks like a mashup between C and Python
15:16 nine mojca: then I don't get why it's not allowed to write :/
15:16 Juerd poldepaor: Have you seen doc.perl6.org yet?
15:16 mojca oh, wait

15:17 nine mojca: thanks for patiently reporting :)
15:18 RabidGravy poldepaor, depends on what you want to automate :)
15:18 mojca thanks a lot
15:18 poldepaor Test automation mostly I guess?
15:19 loren Zoffix, that's very helpful, i think something like this 'for problem or behavior' should be share more, and people will avoid these mistakes
15:19 RabidGravy there should also be a doc page on lists and arrays
15:19 Skarsnik RabidGravy, if you are bored you could fix https://github.com/sergot/http-useragen​t/blob/master/lib/HTTP/Cookies.pm6#L92 I write this so the test pass (because they give expire string looking like DATE1 or DATE2)
15:20 Skarsnik I don't even know how the old code was not failing (probably because the field get lost or something xD°

15:25 poldepaor Has anyone been doing any QA test automation with perl5 and or 6?

15:27 zmyrgel hi, I tried to test perl6 but I can't get panda to install
15:27 zmyrgel it errors out: https://gist.github.com/ano​nymous/00c064486194fc20e270
15:27 zmyrgel I'm using rakudo 2015.12
15:28 RabidGravy that's odd, how did you install it?
15:29 zmyrgel pkg_add rakudo
15:29 RabidGravy on a BSD?
15:29 Woodi mojca: about your moar install: you finished it with included libuv or with one from system packags ?
15:30 gfldex zmyrgel: what does perl6 --version and uname -a say?
15:30 yoleaux 10:41Z <lizmat> gfldex: dd only takes positionals and ignores nameds: that was the only way to get positionals to work and keep order of specification
15:30 Woodi poldepaor: actually Perl was created to look like C and Python was created long long later :)
15:31 Cabanossi joined #perl6
15:31 poldepaor Woodi: That's pretty cool to know. Thanks for pointing that out
15:31 zmyrgel RabidGravy: OpenBSD-current
15:32 Woodi poldepaor: I forgot there was APL somewhere involved :)
15:32 zmyrgel seems there are some changes done to rakudo port recently, just recompiling the package to see if it fixes the panda issue
15:32 gfldex Woodi: not that lone actually. Python was released in 1991. It seams much younger because nobody used it before 2.0, released in 2000.
15:32 mojca Woodi: I used the included libuv just in case, but declared the package to conflict with libuv which is not the best
15:32 _mg_ joined #perl6
15:32 RabidGravy zmyrgel, I *think* the person who did the port was around at some point

15:38 RabidGravy zmyrgel, sorry can't be too much help don't have an OpenBSD handy to help
15:39 loren I misunderstand ? o_O?
15:40 Zoffix Which is a reference to the 4 bash commands mentioned here: http://perl6.org/downloads/
15:40 RabidGravy no, no, but it would be *nice* if the packaged version did work. On OpenBSD it actually does build it from source but just set up in a certain way
15:40 regreg joined #perl6
15:41 mspo the pkgsrc version is broken/too old too
15:41 mspo but a manual build works
15:42 mspo one issue is that nqp needs to be available at build time for the rest but DESTDIR isn't well supported
15:42 mspo so you end up needing to use three distinct packages
15:42 Woodi nine: is it possible that in repositories dist/[sha] would be dist/[sha]/ (directory) and sources and precompilations for a distro live there ?
15:43 loren oh, packaged will be better, i have always compile it on my fedora.Of course, that are reason about fedora has no package about Rakudo now .

15:46 testoh how is perl 5 different from perl 6?
15:47 testoh is anyone here?
15:47 loren Powerful, has a lot of feature .. testoh
15:47 testoh yeah explain please
15:47 testoh can it draw dank memes on its own?
15:48 RabidGravy er
15:48 nine Woodi: precomp files are dependent on the compiler's exact version (including build) while sources and meta data aren't.
15:48 testoh is perl 6 compiled?
15:49 RabidGravy it compiles to bytecode yes
15:49 randomguy I found a small typo on http://perl6intro.com/#_arrays The @animals assignment is using brackets instead of parenthesis. Is this the right place to tell someone about it?
15:49 gfldex testoh: it is comiled to bytecode and there is a fairly limited JIT
15:49 loren https://doc.perl6.org/language.html, perlgeek.de/en/article/5-to-6, maybe you can look these article, testoh
15:50 Skarsnik nine, should precomp follow a fixed version instead of just each compiler version?
15:50 mst randomguy: looks like you want to send an issue or PR to http://github.com/hankache/perl6intro if possible
15:50 RabidGravy we ought to steal the guys who wrote the mono JiT
15:50 randomguy mst: k, thanks
15:50 mst nine: oh, I never followed up, where did you get with the whole 'trying to see through to lower repo precomps' thing?
15:50 zmyrgel yeah I'd like to use the OS provided packages as much as possible

15:53 testoh C U L8R haven wood
15:54 RabidGravy randomguy, in effect it doesn't make a great deal of difference on the outcome:

15:55 testoh you.goFuck(self)

15:57 Skarsnik hm, that's confused me: https://gist.github.com/Ska​rsnik/0fe190087758c4f39232

16:00 RabidGravy oops
16:00 testoh left #perl6
16:00 zmyrgel perl6 seems to get lot of stuff right, like having actual language spec
16:00 RabidGravy randomguy, ah that would explain it, mucho changes on the way lists/arrays work since then

16:01 orbus good morning #perl6
16:01 diakopter moarning
16:01 zmyrgel What I would like to see would be great portability so I could write my stuff on linux and have it run on windows with little to no modificatios
16:01 orbus any NativeCall wizards happen to be about?
16:01 loren zmyrgel, I usually don't want to use what gorgeous grammar, scalability and maintainability is an important aspect, i am a 'c/c++'er
16:01 mst zmyrgel: given the libuv basis that's actually significantly available
16:02 orbus having some problems and I want to see if I'm way off base with what I'm trying
16:02 skids orbus: not a wizard but I've dabbled, go ahead.
16:02 mst orbus: I'm not sure exactly who in here is going to take an interest in that, but I bet there's at least a couple around, so go for it and let's find out who they are
16:02 RabidGravy orbus, depends on the length of beard and it's colour you want but shoot anyway, there are people who do NativeCall stuff
16:02 orbus thanks all :)
16:02 orbus okay, so I'm dabbling with the Oracle client library
16:02 mst I'm so sorry.
16:03 orbus lol
16:03 orbus yeah
16:03 RabidGravy :)
16:03 orbus tell me about it
16:03 orbus and I haven't written any substantial c in probably 15 years
16:03 randomguy RabidGravy: Thanks for the help.
16:03 krshn joined #perl6
16:03 nine mst: the part of module finding that takes ages is parsing the dist meta data, that's stored in a json file. What we actually need of this file is the name of the modules, the version and auth. We already have the quick lookup files for module names. If they contained version and auth, we wouldn't have to parse json anymore
16:03 orbus but anyway, I have a week off and I though I'd take a stab at getting perl6 to talk to oracle
16:03 zmyrgel orbus: luckily the oracle client hasn't changed in that time :)
16:03 Skarsnik I have to use ~~ to test if a class does a role?
16:03 orbus heh
16:03 orbus yeah
16:03 Skarsnik orbus, there is already work on that
16:04 RabidGravy orbus, ah, you may want to speak to abraxxa who isn't actually here it the moment, he's been working on the same thing
16:04 orbus oh nice
16:04 orbus well it's a good learning exercise regardless
16:04 RabidGravy anyway carry on
16:04 orbus but I will keep that in mind
16:04 orbus so the first thing you have to do is call OCIEnvCreate()
16:04 orbus which gives you an environment handle
16:04 Skarsnik https://github.com/abraxxa/DBIish
16:04 mst abraxxa is #dbix-class' longest standing oracle user
16:04 orbus which you then use to do other stuff
16:05 skids m: say List.does(Iterable) # Skarsnik
16:05 camelia rakudo-moar 4cf630: OUTPUT«True␤»
16:05 RabidGravy yep
16:05 orbus yeah, let me see if abraxxa's stuff does what I"m trying to do
16:05 Skarsnik oh thx
16:05 orbus basically this function takes a bunch of pointers to callback functions and things
16:05 orbus most of which you apparently don't actually need
16:05 mst nine: right, because in perl6, effectively, the version and auth are part of the FQ name, ala the PAUSE if and version being part of the DQ dist name on CPAN
16:05 orbus the example code in the docs is passing in 0 for most of the pointers
16:05 perlpilot joined #perl6
16:06 leedo nine: ohhhh, so that may explain why it can take my toy module like 20s to load, but only when i'm useing a bunch of panda installed modules
16:06 orbus so I'm trying to do the same thing from nativecall
16:06 mst nine: I guess that's a question of declaring a new version of the quick lookup file format?
16:06 orbus and it doesn't blow up, but the function is returning -1 which is error
16:06 diakopter leedo: which ones
16:06 Skarsnik Cannot use 'does' operator with a type object.
16:06 RabidGravy it's pass a Code type object I believe
16:06 Skarsnik hm
16:06 nine leedo: if it's much faster on the second try, you're actually waiting for compilation
16:06 leedo diakopter: HTTP::UserAgent and Inline::Perl5
16:06 orbus so hang on
16:06 leedo nine: yeah, it gets down to 10s after the first run
16:06 orbus https://docs.oracle.com/cd/B28359_01/ap​pdev.111/b28395/oci16rel001.htm#i556149
16:07 orbus function definition is there
16:07 mst orbus: it might also help to take DBD::Oracle apart
16:07 diakopter leedo: are you running on a pebble smartwatch?
16:07 skids Skarsnik: I'm surprised .does is hitting the "does operator"
16:07 diakopter [only half kidding]
16:07 leedo diakopter: i5 2.3 GHz :P
16:08 Skarsnik orbus, https://github.com/abraxxa/DBIish/blo​b/master/lib/DBDish/Oracle/Native.pm6
16:08 diakopter leedo: is your hard disk on the moon?
16:08 diakopter [only mostly kidding]
16:08 mst leedo: is your hard drive an EBS volume? If so, have you considered a disk on the moon instead? :D
16:08 leedo diakopter: ssd!
16:08 orbus so I tried defining it like this in NativeCall
16:08 orbus sub OCIEnvCreate(Pointer, int32, long, long, long, long, size_t, Pointer) returns int16 is native('clntsh') { * }
16:08 leedo https://gist.github.com/leedo/803b429654bcbb2c0a24
16:08 orbus okay, let me look at abraxxa's stuff
16:08 orbus that was the next thing I was going to do
16:09 leedo mst: diakopter afaik this hard drive is operating normally
16:09 RabidGravy orbus, it would be Code for the function pointers
16:09 RabidGravy afaik
16:09 mst leedo: sure, I was just complaining about EC2 while I got a chance
16:09 leedo hehe, yeah i've experienced that pain
16:09 orbus hmm
16:09 orbus even if the function pointers shouldn't point to anything?
16:10 Skarsnik skids, I am dumb, it's another line
16:10 orbus looks like abraxxa's stuff is using Pointer for them
16:10 randomguy yay, new version fully installed. all is better now.
16:10 RabidGravy yeah, just pass a Code type object
16:10 RabidGravy that would work too
16:10 orbus like a random undefined one?
16:10 orbus just Code.new or Pointer.new?
16:10 RabidGravy literally foo(Code)
16:11 orbus well that's on the definition
16:11 Skarsnik Oh, you can't use does on an uninitialised object?
16:11 orbus but what do I pass in when I call the function
16:11 RabidGravy that give you NULL
16:11 orbus so I do sub foo(Code)
16:11 orbus but then when I call it foo(??)
16:11 orbus ?
16:11 skids orbus: No call it with Code
16:11 orbus oh
16:12 orbus hrm
16:12 RabidGravy literally
16:12 skids Code is a NULL of type Code
16:12 orbus oh weird
16:12 orbus okay, let me give it a shot
16:12 orbus brb
16:13 Woodi nine: I think that if repo work is interrupted then in current form it will be messed. if distros or modules (sources at least) would be in it's separate dir then it can be easy to verify and repair. and links already are used.
16:13 skyl4rk is it possible to set SA_NODEFER for signal handling, e.g. for signal(Signal::SIGINT).tap: { dostuff }
16:13 orbus Unknown type Code used in native call.
16:13 orbus It didn't like that much
16:13 orbus should it be Pointer in the definition and Code when I call it?
16:14 Woodi nine: as for quick lookup format: cdb like used by tinydns for domains - domain changes and installations arn't so often so read-only database like cdb works good. and it is regenerated on modifing domain or installing module
16:14 zmyrgel ok, rakudo reinstalled with latest changes but panda still gives following: https://gist.github.com/ano​nymous/a7c1830f0ff2ac5864f6
16:15 RabidGravy orbus, that's odd
16:15 mst nine: if I want to understand this stuff, is my best approach to read all of the current src/core/CompUnitRepo tree?
16:15 orbus tried this
16:15 orbus sub OCIEnvCreate(Pointer, int32, Code, Code, Code, Code, size_t, Pointer) returns int16 is native('clntsh') { * }
16:15 orbus my $x=OCIEnvCreate($p,0,Code,Code,Code,Code,0,$z);
16:16 nine mst: after reading jnthn's gist, that's the best source, yes. Of course I'm happy to answer questions :)
16:16 orbus let me try with Pointer
16:16 Skarsnik hm, how I can add a new role to a class outisde the class definition?
16:16 orbus hrm
16:16 orbus well that runs
16:17 orbus but it still returns -1
16:17 skids Skarsnik: For lexical use or as a monkey patch?
16:17 nine Woodi: sounds like you have some interesting ideas. You could try them out easily, since repositories have a clearly defined API and can be plugged into rakduo
16:17 cdg joined #perl6
16:17 orbus going to look what abraxxa is doing a little deeper
16:18 [ptc] should the .precomp dirs (in lib/ and t/04-nativecall/) be deleted as part of `make clean` (or possibly `make realclean`) in rakudo?
16:18 Skarsnik NC use does in its trait x) but it does not work here x)
16:18 RabidGravy orbus, yeah that should definitely work, with a Code there - I'm using it some of my own code (which fails for other reasons)
16:18 orbus well
16:18 cdg joined #perl6
16:19 Skarsnik skids, I am trying to achieve this https://gist.github.com/Ska​rsnik/3b3b2f52faa4128c9931
16:19 orbus it definitely didn't like Code in the sub definition
16:19 mst nine: yes, but it's taking you five minutes a time, the answers are user level so I don't honestly understand them because I'm mid source dive, and you missed the last one entirely
16:19 orbus this is on 2015.12
16:19 orbus with Pointer it doesn't blow up
16:19 orbus but it's still failing
16:19 mst nine: so I'm concluding "christmas has happened to nine, this head cold means I'm asking the wrong questions, time to UTSL first"
16:19 RabidGravy ah in the sub definition maybe it wants  a &foo or something
16:19 orbus it looks like abraxxa is using an array of some sort for the handle it returns though
16:19 orbus instead of a straight Pointer
16:19 orbus need to look at that
16:20 skids Skarsnik: does should be used on an instance, so you'd have to have something in $s first.
16:20 orbus CArray[OCIEnv]
16:20 mst note that I don't think abraxxa's really a C hacker anyway
16:20 orbus and OCIEnv is constant OCIEnv is export = Pointer;
16:20 orbus ohhh
16:20 mst so it's entirely possible that you're both wrong
16:21 orbus so maybe it's supposed to be an array of pointers
16:21 orbus ha
16:21 orbus true
16:21 Atrox joined #perl6
16:21 mst (it's programming, "everything is differently broken" is always a possibility ;)
16:21 Skarsnik skids, I don't know NC use does to extend Str https://github.com/rakudo/rakudo/​blob/nom/lib/NativeCall.pm6#L310
16:21 RabidGravy orbus, maybe if you try "sub OCIEnvCreate(Pointer, int32, &a, &b, &c, &d, size_t, Pointer) returns int16 is native('clntsh') { * }" or some such
16:21 nine mst: I was just eating, is all :) A new file format will be the answer. Of course we didn't think about a versioning mechanism before putting the first version out however...
16:21 orbus what do the & do?
16:22 RabidGravy it's a sigil for a "Callable"
16:22 mst nine: right. so we're going to have to mint some sort of version detection that handles 'pre-christmas unversioned' too
16:22 RabidGravy which includes a Code
16:22 orbus mst: the Oracle call interface is a special kind of nightmare - I can tell that already
16:22 skids Skarsnik: but explicitly-manage is probably called with an instantiated Str.
16:22 orbus this is why when I need to talk to Oracle I usually go through perl or java
16:22 mst nine: which classes/methods are reading/writing that lookup file? I'll have a skim of the code once I've taken a moment to sob quietly into my coffee over unversioned file format ;)
16:22 Atrox Hello, just a little question from a newbie. I'm very interested to try out Perl 6 (after reading the announcement) but Radoku Star is not updated for Perl 6 right? (Its from 2015.11) Should I have to wait or is there any other way to try it? (I'm on Windows) Thanks already!
16:22 nine mst: I guess we just need some VERSION file where non-existence means version 1
16:22 Skarsnik skids, Hooo so the object need to be instancied? damn
16:23 nine mst: it's all contained in CompUnit::Repository::Installation
16:23 TimToady Atrox: depends on your threshold of pain :)
16:23 orbus RabidGravy: let me give it a shot - I'm starting to think the problem is with the output pointer though
16:23 TimToady and on how well your system matches our systems
16:23 Atrox TimToady: so hard to get it working on windows :/?
16:23 skids Skarsnik: unless you monkey-patch the class, which should be avoided unless really necessary, yes.
16:23 orbus namely, the first argument
16:23 TimToady Atrox: windows can be easy if you have the right prereqs installed
16:23 leedo had a thought to try --profile to see what is taking so long using HTTP::UserAgent, since strace wasn't informative. the profile output says it ran for 4.12ms, but it actually took 6s :P
16:24 RabidGravy yeah that's a really peculiar interface, most things just return a pointer
16:24 * TimToady is not a windows expert, but some of our devs work on windows
16:24 Atrox TimToady: is there any resource/tutorial online how I get it working? Or should I just setup vagrant ...
16:24 hoelzro Atrox: I've gotten it built on Windows using Mingw
16:24 Skarsnik skids, I try using this approch to say "This variable from the class B will be DB managed on some ways" without havint to do it in the class itself ~~
16:25 disturbingly_rea Is there a takeWhile or takeUntil construct on lazy sequences? I'd like to be able to do something like `takeWhile {$_ * $_ <= i}, @primes`
16:25 Atrox hoelzro: How? I got MingW installed.
16:25 hoelzro others have had success with the VS toolchain, but I couldn't get that working...
16:25 mst I think for a win32 build you need mingw for gcc plus some sort of git?
16:25 Atrox hoelzro: Just compile?
16:25 [ptc] Atrox: try this out: http://perltricks.com/article/135/2014/11/​18/Building-Perl-6-with-Visual-Studio-2013
16:25 hoelzro Atrox: you'll need git (as mst says) to grab the source
16:25 TimToady and you need perl 5
16:25 hoelzro ah, yes of course =)
16:25 * mst needs to look at what it'll take to make rakudobrew use tarballs optionally
16:25 gist_nb joined #perl6
16:26 hoelzro I did strawberry perl and that worked
16:26 Atrox Awesome. I will take a look. Thank you all!
16:26 skids Skarsnik: "This variable from the class B" perl understands merely as "This variable that can only contain things of the class B"
16:26 [ptc] Atrox: it might help, but could be a bit old.  You have to install from source until the Rakudo Star .msi files are available
16:26 mst I think a lot of us forget there's such a thing as "computers that don't have perl5 installed"
16:26 RabidGravy leedo, how recently did you install H::UA?  I only just an hour ago took a bunch of "no precompilation"s out
16:26 hoelzro in fact, I think that strawberry has all the toolchain you need, sans git
16:26 Arrowhead joined #perl6
16:26 hoelzro mst: I forget that all the time =P

16:27 leedo RabidGravy: i'll update, probably a few days old
16:27 RabidGravy mst that's crazy talk
16:27 Arrowhead What's the canonical way to build and test a module, but not install it?
16:27 mst nine: does the JSON meta format at least have a version?
16:27 skids Skarsnik: what you probably need is something like "class MyDBVar is B does DBROLE { }; my MyDBVar $s"
16:27 leont The only piece of p5 dependency in rakudo's build that'd be hard to convert is Configure, I think
16:27 * TimToady remembers a time when only one computer had perl on it...and before that, everything is lost in the mists of time...
16:27 RabidGravy leedo, yeah the first time might be slowish but after that it's quite zippy comparitively
16:28 Skarsnik skids, yes but I am not fan of having a new class just for that x)
16:28 leedo unfortunately HTTP::UA tests seem to fail currently
16:28 RabidGravy er
16:28 mst TimToady: pretty sure we have regulars who were born after that point.
16:28 RabidGravy whaddyamean?
16:28 skids Well, when you do a does you generate a class, it just does not show you that.
16:28 Skarsnik on older rakudo
16:28 nine mst: not that I'm aware of
16:28 leont I had a brainstorm with Nicholas at some point about having a DSL that could be compiled to Perl5/shell on unix and Powerscript on Windows, but that never got beyond the idea stage
16:29 ponbiki joined #perl6
16:29 [ptc] Arrowhead: probably an incantation along the lines of `prove --exec="perl6 -Ilib" -r t`
16:29 Skarsnik leedo, it probably fail on old rakudo yes
16:29 mst nine: wut. even META.yml had a spec version 10 years ago :/
16:29 leedo Skarsnik: RabidGravy well i've got 6.c release installed :/
16:29 RabidGravy leedo, oh if you've got a rakudo more than a week or so old it will fail
16:29 leedo i'll try again
16:30 Skarsnik skids, wait, if I still can use does on instancied stuff it's fine for me ^^
16:30 RabidGravy it definitely passed it's tests before I pushed the change
16:30 skids m: (1 does role { }).WHAT.say # Skarsnik: that's actually a new class there.  Classes are pretty cheap.

16:31 mscha joined #perl6
16:31 Skarsnik skids, because I don't work to work on a "special" class, just attach them the role before saving them in a DB for example
16:31 Skarsnik *want
16:31 mst nine: ah well, 'no version is version 0' isn't a terrible thing really and then we can go from there
16:32 mst nine: I've done that on plenty of projects where I failed to add versioning to a format early enough; it seems to be one of those mistakes that's totally possible to make repeatedly even when you know it's a terrible idea
16:32 skids Skarsnik: sounds like a plan.  Classes/runtime mixins are supposed to be relatively cheap these days.
16:32 nine mst: same here
16:32 Skarsnik another question is how to strip a role from a class x)
16:33 [ptc] Arrowhead: no worries :-)

16:36 orbus oh, I had another question
16:36 orbus (not about arrays)
16:36 skids :)
16:36 camelia joined #perl6
16:36 orbus anybody know the current status of Inline::Perl5?
16:36 skids Pretty working.
16:36 nine mst: for the short/ files we can in the future write <sha>.full files containing all the info needed and leave the <sha> files as they are and transparently fall back to them if no .full file is available.
16:36 orbus tried building on two different machines yesterday  and it compiled but failed all the tests
16:36 RabidGravy I'm sure there's someone here who knows
16:36 orbus one was ARM though
16:36 orbus and the other was x86_32
16:37 lalos left #perl6
16:37 orbus so that might be the problem?
16:37 RabidGravy ARM may be asking for trouble
16:37 orbus yeah, I kind of wrote that one off
16:37 mst nine: sounds reasonable, though we definitely want to stick a version on the front of the contents anyway since presumably we'll've made more mistakes implementing .full files
16:37 orbus but the x86 one didn't work either
16:37 nine orbus: I'd never even thought that ARM was on the table. x86 should be possible, but you may also be the first to actually try it.
16:38 orbus I did get rakudo to build on my Raspberry Pi2 though
16:38 orbus ha
16:38 nine orbus: I tried to be careful about native types, but they have not all been available when I started and it's easy to overlook something.
16:38 RabidGravy yeah, I've been testing it regularly on RPi
16:38 nine orbus: can you get me a gdb backtrace?
16:38 orbus I'm the same guy who's been trying to build on sparc lately
16:38 orbus on arm?
16:38 Skarsnik I get the same issue on x86_32
16:39 nine orbus: on x86_32
16:39 orbus oh
16:39 orbus yeah probably - I have an old laptop with ubuntu on it
16:39 orbus that's what I was trying it on
16:39 orbus have to install gdb
16:39 nine I didn't even know that rakudo worked on ARM
16:39 orbus and figure out how to make a backtrace :)
16:39 Skarsnik could it be an NC oversight?
16:39 nine Skarsnik: possible
16:39 Skarsnik like a Int or Num used instead of int32, num63
16:40 vividsnow1 joined #perl6
16:40 TimToady num63 is an odd type
16:40 TimToady not quite sure we support that one yet ;)
16:40 Juerd num62 is even again though :)
16:40 orbus one of these boxes I forced it to install even though the tests failed
16:41 orbus and it core dumps if you try to load the module anyway
16:41 orbus but I couldn't find the core file
16:41 Skarsnik sub p5_is_array(Perl5Interpreter, OpaquePointer)
16:41 Skarsnik returns int { ... }
16:41 Skarsnik could be that
16:41 orbus need to check which box it was
16:41 orbus might have to reinstall rakudo to get a clean install
16:42 orbus must have been the pi
16:42 orbus okay, let's see here
16:42 leedo RabidGravy: ok, nuking my install seems to have fixed it... i've had to do this a lot.
16:42 mst TimToady: hey, I started off on arm26 ... arm is awesome but also totally weird ;)
16:42 orbus I was trying to install from panda
16:42 RabidGravy leedo, yeah, it was suffering a precompilation related issue a few weeks ago
16:42 orbus I guess I better clone the repository?
16:43 Atrox Thanks guys! Got it running on Windows. Was not even that hard thanks to that tutorial. :)
16:43 [ptc] Atrox++
16:43 leedo RabidGravy: ah, well thanks for fixing! i'm glad it exists :)
16:43 leedo hopefully i can remove my Inline::Perl5 dependency soon
16:44 nine orbus: yes, makes everything easier
16:44 RabidGravy well, let us know what else you might made and we'll see if we can help ;-)
16:44 leont [ptc]: that looks rather interesting :-)
16:45 orbus okay, so perl6 configure.pl spat out this
16:45 orbus gcc -Wall p5helper.c `perl -MExtUtils::Embed -e ccopts -e ldopts` -shared -o ./resources/libraries/libp5helper.so -fPIC -g
16:45 Skarsnik nine, to sad you don't export your routine in i:p5 so I can't use NativeCall::Typediag directly, but yes, you should not have int in that
16:45 orbus so that seems right-ish
16:45 leedo RabidGravy: i've started https://github.com/leedo/p6-web-scraper - just messing around though

16:54 RabidGravy On an Rpi2 : "Short: 2, Int: 4, Long: 4" (sizeof(short),sizeof(int), sizeof(long))
16:54 Skarsnik apparently there is a int64_t in stdint.h
16:54 Skarsnik it's probably for this kind of case
16:54 molaf joined #perl6
16:55 RabidGravy "long long" is int64
16:55 Skarsnik let me change the NC doc to be more explicit x)
16:55 Skarsnik like: int64 (For explicitly 64 bits integer in C)
16:56 orbus okay
16:56 orbus sorry, keep getting pulled awa
16:56 orbus away
16:56 RabidGravy I think the "long" may be the one that changes most 32 vs 64
16:56 _mg_ joined #perl6
16:56 orbus so with the original clone I made
16:56 nine mst: what do you think? Should we blow up loudly on stubling over inconsistencies within the repo (like short/ points to a dist, but we can't find the dist file), or should we ignore them and give the next-repo a chance?
16:56 orbus running t/autoload.t by itself segfaults
16:57 nine Skarsnik: also aren't there platforms where int is 64 bit?
16:57 orbus I'm not super familiar with github
16:57 orbus mostly worked with git locally on solo projects
16:57 mst orbus: it's git plus crayon drawings plus animations that give you a headache
16:57 * mst kicks github off his lawn
16:57 orbus okay, I just did git pull
16:58 orbus and I see your commit in the log
16:58 mst nine: not entirely sure.
16:58 orbus so I guess we're good there
16:58 orbus let me re-test
16:58 nine orbus: did you run make after the git pull?
16:58 nine orbus: ignore that, you don't have to this time
16:58 mst nine: actually, I think if you have something corrupt in the top repo, you should be really suspicious of the top repo entirely
16:58 timotimo btyler: i'll watch the perl jam 2 talk just so i know what's going to come at us
16:58 nine orbus: can you please try perl6-gdb-m -Ilib t/autoload.t
16:58 orbus one sec
16:58 orbus after the git pull I did make clean
16:59 orbus then I re-ran configure
16:59 orbus now I'm doing make test
16:59 RabidGravy nine, on x86-64 (i7) int is still 32 but long is 64
16:59 orbus still failing
16:59 nine mst: yeah, I guess blowing up as loudly as possible is the way to go. Otherwise we'll never find the bugs leading to the inconsistencies in the first place
16:59 orbus let me try the gdb test
16:59 mst nine: also I haz epic fear of other things in the same repo only -looking- not-corrupt
17:00 Skarsnik nine, hm, tricky question maybe it work if int32 work as a C int in the internal?
17:00 mst nine: so I think an immediate HCF before things go even more badly wrong is going to be the best thing to start with
17:00 orbus it's thinking
17:00 mst nine: we can always add a Repo::MightBeBroken::DontWorryTooMuchAboutIt or something later :)

17:08 orbus this *is* my vacation
17:09 orbus I'm off work all week so I have time to mess around with perl
17:09 Skarsnik abraxxa had an issue with CArray[CArray[int8]] when working on DBIish Oracle x)
17:09 Skarsnik https://github.com/niner/Inline-Perl5​/blob/master/lib/Inline/Perl5.pm6#L88
17:09 RabidGravy well as we have discovered, there a thousand and one ways to break an installation and people don't understand lists
17:10 orbus Skarsnik: interesting
17:10 jme` joined #perl6
17:10 RabidGravy Skarsnik, that problem was actually something bit more general about typeconstraints working properly with typed CArrays
17:10 orbus is there any other documentation on native call besides http://doc.perl6.org/language/nativecall
17:10 orbus ?
17:11 RabidGravy no, and even that isn't complete
17:11 orbus I've seen some things in DBIish that don't seem to be documented
17:11 nine mst: I've already got plans for how custom repository classes can be registered by just installing them. It involves a directory containing e.g. a "github" file, containing the class name "CompUnit::Repository::Github". This directory is read by CompUnit::RepositoryRegistry to populate %short-id2class
17:11 Skarsnik nine, you still have some int instead of int32
17:11 RabidGravy orbus, the tests in the rakudo/t directory are a good source of information
17:11 orbus ah, okay
17:11 orbus will take a look
17:11 orbus when I'm less burned out
17:11 Skarsnik https://github.com/niner/Inline-Perl5/​blob/master/lib/Inline/Perl5.pm6#L169 for example
17:12 Skarsnik Hm, there is not that much missing in the doc for the C part
17:12 orbus yeah
17:12 mst nine: let's not implement said plans until we've thought it through at more length
17:12 Skarsnik maybe thing about nativecast
17:12 orbus well like, the docs don't talk at all about OpaquePointer
17:12 mst nine: e.g. I don't understand why you'd have 'github' as a filename, rather than just a 'repoformat' thing
17:12 orbus and what the difference is between that and a normal Pointer
17:12 Atrox Hi, another question in terms of modules. Does the name of the github repo really has to match the name of the module?
17:12 Skarsnik OpaquePointer is an old thing
17:13 Skarsnik Atrox, not really, lot of module are nameed like perl6-module
17:13 Atrox Skarsnik: Great. Thanks. Because I want to name it the same way :)
17:13 nine mst: distro packages
17:13 mst also, I'm not convinced that the same repository should necessarily always map to the same repo class
17:13 Atrox Skarsnik: I just asked because in the official guide it states that. Thank you.
17:13 RabidGravy github doesn't let you put :: in a repo name afaik
17:14 mst nine: eh?
17:14 RabidGravy Atrox, the important part is the name in the META6 file
17:14 nine mst: when CompUnit::Repository::Github is installed via distro package, all it has to do is place a file in a directory to register the name. Otherwise we'd need a post-install script modifying the repoformat file
17:15 nine mst: and I think, right now CompUnit::Repository::Installation has the same nice characteristics.
17:15 orbus nine: I need to head out for a bit - is there anything else you want me to try before I go?
17:15 Atrox RabidGravy: Ok nice, then it is working as expected. Thank you for the answer.
17:15 mst nine: I'm not sure what you're imagining here.
17:16 mst nine: I was talking about having a repoformat file in the root of the repository itself
17:16 nine mst: ooooh
17:16 * lnrdo installed latest Rakudo with Panda and Task::Star. It only worked after deleting .rakudobrew folder and starting again from scratch.
17:16 nine mst: yeah, of course. That does have a bit of a startup performance penalty though, since we have to read a file for every default repo
17:16 lnrdo But it worked after all.

17:17 yoleaux patrickz: I'll pass your message to ugexe.

17:33 nine RabidGravy: that's a use case that really was better supported by the old CompUnit. With the new architecture, you'll have to ask for matching modules, probably get CompUnit::DependencySpecifications back and have the repo search all over just to load them.

17:37 Skarsnik TimToady, at run time, considering the role get 'affected' to a class
17:37 gfldex Skarsnik: asking a class for a base class is kinda wrong, it's objects that have a base class. And there is monkey typing and mop-magic. So you have to ask at runtime, likely so more then once.
17:37 TimToady we make <> special for rat and complex because otherwise precedence might interfere

18:54 dfarrell hey folks, is there any documentation available on using different versions of the same module in the same program?
18:55 gfldex hankache: i do agree that there is a hole. I do not agree with a Range as a good way to represent something that can have holes.
18:55 nine dfarrell: I think, that's not fully supported yet
18:55 nine dfarrell: lots of infrastructure is already there, but not hooked up together.

18:57 dfarrell nine: ok, thanks. That's what I thought too, until I read this post: https://wendyga.wordpress.com/2015/12/25/why​-would-you-want-to-use-perl-6-some-answers/
18:57 autarch and I have two other subs (magic_descriptor and magic_buffer) that work exactly the same way and don't cause warnings
18:57 lucasb so, there is a difference when you create an array with 'my @a; @a[10] = 42' and when you type 'my @a = Nil,Nil,...,42' ?
18:58 Skarsnik autarch, that pretty weird
18:58 Skarsnik I am not sure the --> Str work?
18:59 autarch here's the code - https://gist.github.com/au​tarch/d7153a6371f430289c10

19:31 Skarsnik That why I exclude it in NC::TypeDiag x)

19:32 masak lizmat: so, that's one of them 61-second minutes, right?
19:33 Skarsnik RabidGravy, damn this execption is from Core
19:33 lizmat masak: yup
19:33 Skarsnik Did you get bt in NC at some point?
19:34 masak lizmat: I'm a bit fuzzy on the exact details of the .later algorithm, but when you say .later(:1day), it's supposed to take you to "the same" hh:mm:ss on the next day.
19:34 masak lizmat: which isn't possible in this case. so it truncates.
19:34 masak lizmat: whereas if you say "this exact amount of seconds later", it's pretty clear you don't want the truncation
19:34 Skarsnik lucasb, btw my goals was to get the name of A and not R x)

19:54 woolfy Hi all.  I'm in a discussion that is too much over my head.  How well is Perl 6 supporting (has implemented) IEEE 754? (I did try to find this myself, and found this on Wikipedia: https://en.wikipedia.org/wiki/IEEE_floating_point ) (but trying to find the specifics in Perl 6 code is over my head.
19:55 woolfy (discussion is elsewhere, not here)(d'oh)
19:55 [Coke] mst: I was never a fan of having a bajillion p5 ports (one per module); I suppose if it's automatable...
19:55 perigrin mst: buy a windows laptop and install hte msi?
19:55 * perigrin hides.
19:55 [Coke] mst: use the non msi version; works fine.
19:55 mst perigrin: well if we're trying to be *sensible* I think the answer for both windows and OS X should be "here's a dollar, get yourself a debuntu VM already"
19:55 woolfy I've read Ovid's helpful blog: http://blogs.perl.org/users/ovid/2015/02/a-lit​tle-thing-to-love-about-perl-6-and-cobol.html
19:55 [Coke] you don't need macports to install R*

19:57 autarch just run "perl6 t/basic.t"
19:57 mst perigrin: perhaps
19:57 woolfy [Coke] thanks, maybe I should stick with mentioning Ovid's post.
19:57 mst what I'm mostly saying is "we seem to be trying to make rakudo easier to get for macports users"
19:57 mst given that's the goal, we should at least have -a- way to get to an R* atop a macports rakudo
19:58 nine Ok, which NativeCall data type should I use if I need a 32 bit int on a 32 bit system, but a 64 bit int on a 64 bit system? Because that's what perl 5's IV is.
19:58 [Coke] So, I think my plan makes some sense; it's just a PITA to create N ports.
19:58 Skarsnik That a good question nine
19:58 [Coke] [meta] we might need to starting using threads to indicate what we're talking about. getting noisy in here. :)
19:59 lucasb or split another channel
19:59 awwaiid m: say "newline\ntest"
19:59 camelia rakudo-moar a2c1d8: OUTPUT«newline␤test␤»
19:59 Skarsnik nine, is that long?
19:59 perigrin [Coke]: to answer your earlier question ... as far as I can tell most of the ports systems on OSX (the two or three I've used at least) tend to be hands off once they've gotten you bootstraped into the language's build system.
20:00 nine Skarsnik: don't think so. I'm already using long and it's wrong for orbus's system as it seems
20:00 mst right, which is why I was thinking "we should make sure there's a defined way to get to a full R* using panda (or whatever), and make sure there's a port for panda (or whatever)"
20:00 perigrin ^^^
20:00 mst [Coke]: the threading was fine until somebody randomly stuck [meta] in front of a line in a weirdly un-irc-ish way and then my mental parser crashed :D
20:00 perigrin [Coke]: Added bonus to mst's plan is that it works for homebrew users too :)
20:01 RabidGravy autarch, I'd start with int32 rather than int
20:01 Skarsnik nine, our native long     is Int is ctype("long")     is repr("P6int") { };
20:02 Skarsnik wait
20:02 Skarsnik that's dumb
20:02 cygx joined #perl6

20:05 Atrox Hi, does anyone have time to take a look at: https://github.com/Atrox/haikunatorperl Would love to get feedback on the code itself.. I don't know if this is the idiomatic way of writing perl ._.
20:06 Skarsnik haikunate(:tokenHex(True)) you don't need the True here ^^
20:06 Skarsnik :tokenHex
20:07 Skarsnik But this look fine
20:07 Atrox ah nice.
20:07 autarch Atrox: I don't know about Perl 6 but in 5 we use "snake_case", not "camelCase" - in 6 I mostly see "snake_case" or "what-is-this-case"
20:08 autarch and by "we" I mean Perl 5 people who didn't first spend years writing Java ;)
20:08 Atrox autarch: yeah, I thought about the same... but I didn't find any style guide or linter at all for perl 6 :/
20:08 masak autarch: kebab-case, it seems to be called
20:09 Skarsnik kebab case is getting more common
20:09 mspo I just saw the term snake_cast for the first time today
20:09 mspo case
20:09 autarch I just realized it should be flying-snake-case!
20:09 autarch that's so much better than kebab

20:13 mojca RabidGravy: thank you; [Coke]: yes, I also imagine one port/package per module, but I wanted to get the idea about what else was missing
20:13 h3kker joined #perl6
20:13 orbus reverse case - all identifiers should be desrever for added clarity
20:14 [Coke] mojca: just getting panda working and then using panda to install modules is also fine. (and lets us minimize the amount of work, and have similar instructions for homebrew)
20:14 [Coke] you'll need at least that much anyway.
20:15 nine Skarsnik: the P5 type is detected and generated by the Configure.pl script
20:15 mojca [Coke]: from what I've seen homebrew installs just rakudo-star
20:15 Skarsnik nine, in perl5 lib?

20:18 Skarsnik look like you will need to do the same check?
20:20 timotimo lol the perl jam 2 dude showed an exploit with CGI.pm with code copied from its docs
20:21 Skarsnik m: role R { method foo{say self.^name}; method bar{self.foo()}}; class A {}; my $a = A.new; $a does R; $a.bar
20:21 camelia rakudo-moar a2c1d8: OUTPUT«A+{R}␤»
20:21 nine timotimo: no, if it were copied from the docs it would not have been exploitable
20:21 Skarsnik hm, How I can get only A ?
20:21 nine timotimo: he exchanged upload and param
20:21 timotimo nine: does it use << >> in the docs?
20:21 gfldex timotimo: that talk is fine advertisement for Perl 6
20:21 nine timotimo: oh, maybe you mean a different "exploit"
20:21 timotimo Juerd: i heard you gave him a question
20:22 timotimo nine: where an uploaded file turned into a string instead of FD and he used it with < > and put | at the end of one of the params
20:22 nine timotimo: that's the one I mean. It should have been my $fh = $cgi->upload('file'); not $cgi->param('file')
20:22 Juerd timotimo: Yes, I did. The 'signal angel' did mangle the question a bit. But it's okay.
20:22 timotimo oh, he only used upload in the if statement, right?
20:23 gfldex the importent bit is that the string is ARGV, and CGI.pm will fill ARGV with the user input for you
20:23 nine timotimo: nowhere in CGI's docs does it ever tell you that param returns a file handle
20:23 Juerd nine: It used to.
20:23 nine timotimo: yes, it's completely his own screwup
20:23 timotimo Juerd: i was a signal angel in the past, it is quite hard to get that stuff right
20:23 Juerd nine: A long, long time ago.
20:23 Juerd timotimo: I phrase literal questions :)
20:23 leedo timotimo: wasn't CGI.pm even removed from perl 5 core?
20:23 Juerd leedo: It was
20:23 Juerd timotimo: Are you here?
20:24 flussence leedo: precisely *because* people keep screwing it up like this :)
20:24 nine And the crap about "the whole perl security module is based on <his very own bullshit> asumption!"
20:24 leedo that is weird, the abstract on that talk was all about "exploiting perl 5 core" or some such stupidity
20:24 timotimo Juerd: i am not
20:24 timotimo nine: can you give me a direct link to that part of the docss
20:24 Skarsnik well having <> doing special stuff with ARGV is weird xD
20:24 Juerd Skarsnik: Yes, I agree that <ARGV> doing 2-arg open is a security issue.
20:24 leont leedo: he's a lying bully, I didn't believe that for a moment
20:25 frobisher joined #perl6
20:25 nine timotimo: http://perldoc.perl.org/CGI.html​#PROCESSING-A-FILE-UPLOAD-FIELD
20:25 leedo leont: yeah, sounds like it
20:25 Juerd leont: Well, the point about <ARGV> and 2-arg open is valid.
20:25 timotimo http://perldoc.perl.org/CGI.html​#PROCESSING-A-FILE-UPLOAD-FIELD - this doesn't have it
20:25 Juerd leont: It's a documented feature but an intensely dangerous one.
20:25 timotimo Juerd: doesn't <<ARGV>> not give you that problem?
20:25 gfldex leont: he got a working exploit and that means he is right
20:26 nine gfldex: an exploit in his own code
20:26 nine I can write exploitable code easily and blame it on some language
20:26 gfldex gfldex: i don't think he wrote bugzilla
20:26 leont I hate the feature as much as anyone else (except tchrist, who seemed to love it), but I wouldn't call that "exploiting perl 5 core"
20:26 Skarsnik what the use case to have <ARGV> to something?
20:26 timotimo nine: that doesn't have <$foo> in it at all
20:27 Juerd timotimo: IIRC something like that was introduced, yes.
20:27 gfldex nine: and his 2nd bit of code came from CGI.pod
20:27 timotimo and what idiot threatened this dude's life?
20:27 Juerd timotimo: I don't believe that anyone did. The dude has not refrained from lying about other stuff and I think this too is imagined, not real.
20:27 flussence (and how hard was he baiting them to get that kinda reaction?)
20:28 timotimo flussence: well, last year's talk
20:29 dha Oh, is someone lying about stuff again?
20:29 gfldex flussence: if you take the troll bait, you are the troll
20:29 timotimo let's not just call him a liar just yet
20:29 timotimo until we find where he copy-pasted that piece of code from
20:29 Skarsnik hm what the eqv of my ($var1, $var2) = $str =~ /(\d);(\d)/ ?
20:30 flussence timotimo: well that was a github screenshot, so could be a million different places
20:30 gfldex and he got a point. It's incredible hard to write secure perl 5 code. What doens't make him less of an asshole ofc. There is however no reason not to learn from an assholes good points.
20:30 Juerd gfldex: He had 1 good point and a dozen instances of utter bullshit
20:30 nine gfldex: no, it's not hard at all if you just read the docs
20:31 Juerd gfldex: I disagree that it is hard to write secure Perl 5 code. It is hard to write really secure code in any language, Perl 5 being *easier* to write secure code in, than the average of all languages.
20:31 leont Yes, what Juerd says
20:31 nine gfldex: the whole DBI docs tell you to use placeholders. Not a single example strays from this. Some Bugzilla coder didn't get the message and suddenly it's "Perl's security module" that's wrong
20:31 timotimo Juerd: except if you're not careful in p5 about what's scalar, list, array or hash the functions you use will suddenly behave extremely differently
20:32 cygx joined #perl6
20:32 leont timotimo: there aren't that many functions that have that issue, really
20:32 timotimo maybe

20:32 timotimo cygx: thanks for spotting that!
20:33 mst gfldex: the file upload documentation mistake is extremely unfortunate, and definitely needs fixing
20:33 timotimo cygx: where can i access that on the 'net?
20:33 cygx timotimo: CPAN?
20:33 leont Juerd: Also, our knowledge of how to write secure code is improving. Some issues were gravely underestimated in all code 15 years ago
20:33 timotimo i am on cpan
20:33 mst OTOH CGI.pm hasn't been a recommended way to write code for some time
20:33 timotimo i have a download button or a "source" button for the pod only

20:33 Juerd leont: Agreed
20:33 timotimo mst: hasn't the reaction to CGI been "NO! STOP! GO AWAY! NO!" for a long tmie?
20:34 mst timotimo: yes.
20:34 mst timotimo: and then he rages about Catalyst and Mojolicious having different APIs ... which we did specifically because CGI.pm's were pretty terrible :)
20:34 timotimo i can't find the examples/ thing yet
20:34 mst timotimo: yeah, so if you click the CGI-4.25 link at the top of the page
20:34 mst timotimo: that takes you to https://metacpan.org/release/CGI
20:34 mst timotimo: which lists the examples

20:35 timotimo that was hard to find
20:35 autarch RabidGravy: how'd you do it?
20:35 timotimo thanks
20:35 timotimo now i see it
20:35 timotimo and yeah, it's bad
20:36 RabidGravy I'll PR it but basically magic_setflags needed to be a sub *and* you were using open() instead of magic_open()
20:36 * Skarsnik spend 4 hours generating 2 sql querry, is happy
20:37 timotimo nice. CGI.pm's readme actually tells potential users that there's better stuff available and what it is
20:37 timotimo gotta run grocery shopping now!
20:37 autarch RabidGravy: ah, I see - maybe NativeCall needs some more defensive code so it doesn't segfault on that sort of error

20:44 flussence (one day in the distant future, we might even have a DOM-tree-style API...)
20:45 masak flussence: working on it :)
20:45 ChoHag Does EVAL $string do anything other than what eval $string does in perl 5?
20:45 webstrand joined #perl6
20:45 flussence masak: um, would `<item>+ %% <sep> <trailing-sep=.sep>?` work or am I misunderstanding %%?
20:46 autarch ok, so it doesn't segfault, but it doesn't actually work - how do I go about debugging NativeCall-using code? Like if I want to see what's happening on the C side?
20:47 lizmat ChoHag: it parses perl 6 by default ?
20:47 nine autarch: gdb?
20:47 autarch nine: ugh, right
20:47 * autarch dusts off his minimal gdb skills ...
20:47 nine that's all you need :)

20:47 masak flussence: ooh, that's a nicer solution than the one I ended up with. :)
20:47 perlpilot masak: you could also probably count the items and the separators
20:47 gfldex ChoHag: it will not inject anything into the surrounding scope
20:47 masak flussence: but then it'd need a `%`, not `%%`
20:47 cygx masak: $<sep> == $<item>
20:48 webstrand What's the use of .precomp files? I'm trying to package panda for my distro, and when I give panda's bootstrap a prefix, it sticks a bunch of .precomp files in there. What should I do about them? I can't include them in the package because the names sometimes conflict with other modules.
20:48 masak perlpilot: yes, but that'd require me to catch all the separators, and I only really care about the trailing one
20:48 awwaiid ChoHag: it makes a new lexical scope, parses/compiles. unlike perl5 it does not catch exceptions.
20:49 lizmat awwaiid: good point  :-)
20:49 lizmat I had completely forgotten about that
20:49 ChoHag Right.
20:49 flussence webstrand: you can safely rm -rf .precomp/, it usually happens because test files contain a "use lib" line
20:50 orbus perl6 basically compiles a module the first time it's run and stores the intermediate result right?
20:50 ChoHag So next step, Why does function-which-returns-an-object ~~ Type::Name (inside an EVAL because I'm debugging and Type::Name isn't loaded at that point) return false even though the object returned from the function does indeed have Type::Name mixed in to it?
20:50 leont ChoHag: EVAL is currently rather buggy. It doesn't work well in modules, see #126839
20:50 orbus I think python does something simmilar
20:50 flussence mono does the same thing too
20:50 ChoHag And if the smartmatch isn't, how can I force that specific test?
20:50 orbus been a while since I looked at python
20:50 webstrand flussence: Thanks. Is there an env-var I can set to generate them elsewhere?
20:51 leont ChoHag: probably because your function needs to know about your Type::Name
20:51 ChoHag Ah!
20:51 ChoHag Because the function returns more than just the object.
20:52 flussence webstrand: not for .precomp specifically. I had a hack that moves them all to ~/.cache/perl6/ but people decided it wasn't enough of a problem to change it
20:52 autarch uh, how do I start perl6 under gdb? since my "perl6" is a perl6 wrapper that calls a shell wrapper that ... ?
20:52 leont perl6-m-gdb
20:52 hoelzro autarch: I believe rakudo ships perl6-gdb-m
20:53 autarch hoelzro: yes it does - that works
20:53 orbus I'm sure this has probably been discussed to death, but what was the thinking behind having a Match object coerce to a string with funny corner brackets around it?
20:53 orbus like if $x is a Match object
20:53 orbus and I do say $x
20:53 orbus I get 「x」
20:54 orbus but if I say $x.Str
20:54 orbus I get x
20:54 flussence orbus: you asked for a human-readable string (by using say instead of put), so it calls .gist instead of .Str
20:54 leont That's because it's the .gist, not the .Str
20:54 hoelzro orbus: that's .Str vs .gist
20:54 orbus hrm
20:54 orbus and .gist is supposed to be more a representation of the object as a whole?
20:55 hoelzro it's a friendlier representation
20:56 ChoHag Friendlier if you have a suitable font.
20:56 orbus heh
20:56 orbus I'm just starting to explore the new regex engine
20:56 ChoHag Perl 6 likes to show me boxes.
20:56 orbus maybe it should be the poop emoji
20:56 RabidGravy autarch, btw the magic.h has a lot of const char * in the arguments, these should have explicitly-manage($str) called on them before passing them to the NC sub
