cale2 Hey what do you guys think of Haskell? Ever tried to learn? 02:06
brokenchicken One of earlier Perl 6 compilers was written in Haskell
And many people who know it point out Perl 6's FP suckiness 02:07
:)
cale2 I knew about Pugs. But it seems like Audrey (was that who wrote it?) was one of the few that actually worked in Haskell 02:08
brokenchicken I think she's the one who started it yeah
geekosaur several of us know Haskell... but not as well as Audrey. (I've lost count of the number of times I've hit the Pugs source and bounced) 02:10
cale2 I'd love to talk with her about her experiences in both worlds
Because she must have thought Haskell wasn't as fun as Perl6 since the whole "optimised for fun" thing came around that time :D 02:11
geekosaur: you're literally in the haskell room with me. Are you an imposter? 02:12
geekosaur ?
cale2 geekosaur: There's a person with your name in #haskell 02:14
geekosaur yes, that would be me. is there some rule I'm only allowed to be in one channel at a time? 02:15
TimToady cale2: what is this, tribalism of some sort?
yoleaux 20 Jan 2017 08:48Z <AlexDaniel> TimToady: so is this supposed to warn? 'hello' [&say] 'world'
20 Jan 2017 08:48Z <AlexDaniel> TimToady: github.com/rakudo/rakudo/commit/acece7b2f7 (#00007997)
geekosaur (in fact I started hanging out in here and in #haskell in 2006, several months apart)
cale2 geekosaur: I'm just joking. I figured everyone else in the haskell channel knew the language. 02:16
TimToady We need people who live in one village all their lives, and we need people who go from village to village exchanging good things. That's anthropology. 02:17
cale2 I don't really know the culture of IRC yet. For example, I never knew freenode and mozilla were different IRC networks altogether
02:18 cpage_ left
cale2 TimToady: That's a good thought to have. It produces utterly wild things like this: github.com/timo/ADT 02:19
geekosaur sadlyI think my only contribution to perl6 was, in attempting to implement the file test ops in pugs, causing their syntax to get changed from p5's -X to adverbial :X --- and in asking aquestion about how -s was to work, kicking the legs out from under the original smart match implementation
:)
brokenchicken :) 02:20
TimToady we're officially okay with not knowing things here, at least temporarily, as long as it doesn't veer off into "what you know that ain't so", like some politicians I could name...

cale2 I know there is argument destructuring in p6, but what about matching of specific values that are passed in? 02:39
multi one(1) { true }; multi one(x) { false }; 02:40
brokenchicken That works too 02:42
For Str a Numerics

cale2 Just realized instead of teaching OOP in his book, he could have made DNA a subset of Str that only includes ACGT, for example 02:58

brokenchicken That'd be pretty damn slow
MasterDuke .seen kyclark
yoleaux I saw kyclark 9 Dec 2016 20:20Z in #perl6: <kyclark> But my boss says that my book should be able to count for my master’s thesis. Doubleplusgood! I will keep working on it.

how do I fix this?

04:40 japh-com left
Todd Git-cmd by chance? 04:41
araraloren You can find a batch file `vscarsall.bat`, before you run panda run it
in mcirosoft visual stduio installation directory 04:42
such as `Program Files (x86)\Microsoft Visual Studio 14.0\VC`
04:42 faraco joined

geekosaur for nmake I suspect you need go.microsoft.com/fwlink/?LinkId=69...lcid=0x409
(visual studio community edition) 04:50
araraloren Todd, panda didn't need that, Inline::Perl5 need that
Todd I am installing it 04:52
It says it need 7GB. Is that normal? 04:53
araraloren Yeah, you can make a custom install 04:54
geekosaur I think there might be a command line tools also, that's a full IDE 04:55
araraloren Actually it is existed
Todd I think at this point it would be better for me to switch back to Perl 5. There will be other things to code in 6 in the future
araraloren Windows sdks privides that tools, maybe 04:56
Todd Mainly becasue I have to role this out acros multiple computers and can't have a YUGE installation proceedure
araraloren Use Perl6 under linux should have more comfortable ..

faraco and, does anything else (core) depends on ufo? I gonna made a pr to task-star, if okay. 10:33
oh nevermind 10:34

10:38 Actualeyes left
RabidGravy mind you I've probably still got modules that mention it in their README 10:39
timotimo nothing depends on it, aye
potentially, yeah
we have all-modules for that
RabidGravy simply because I haven't got round to updating them
timotimo yup, there's a whole lot of 'em 10:40
gist.github.com/timo/2a04435099e22...b8d67dd3f6 10:41
you definitely do lead the bunch 10:42
faraco erm, so there is Getopt::Long, but..the documentation is just. Erm. Any alternative for, *right now*? 10:43
timotimo :( 10:47
10:48 parv joined
timotimo there's Getopt::std which doesn't give you long options 10:48
RabidGravy well, apparently 23 of my modules mention "ufo" in their README 10:49
timotimo yup.
faraco timotimo: thanks!
timotimo that happens when you copy-paste the same readme over all your projects :)
RabidGravy maybe I'll spend some time fixing that today
timotimo why not let someone write a script that goes through all modules in my list and makes pullrequests? 10:50
i.e. pop open an editor for each, in turn, and go
actually ...
10:50 agentzh left

RabidGravy: if you have permissions for that, sure
RabidGravy just my modules
so yeah I have permission
faraco moritz: I feel bad. Using both Perl and Perl 6, also grep and sed. Yet, only know how to use s/blah/ploof/g, and any other simple construct of regex. :'( 11:06

kalkin- hi #perl6 11:46
XMPP provides different auth mechanism via SASL. The server tells me the supported mechanisms it can use. The current Net::XMPP library implements only one method (PLAIN). What would be the most perlish way to extend it to be future proof for any new mechanisms, while not hardcoding them in Net::XMPP? 11:48
My first thought would be doing dependency injection and provide my custom auth mechanisms during initialization 11:49
11:49 faraco left
kalkin- Another Idea would be to provide a custom role MyAuth and do in my client Net::XMPP does MyAuth and overwrite this way the Net::XMPP auth mehtod (which currently doesn't exists, but can be patched) 11:50
A third way would be to provide during initialization an hash consisting of AUTH-MECHANISM => MyAuthRouting() 11:51
RabidGravy runtime application of the role, probably keyed on the name provided in the Auth header 11:56
I've done something similar in some code, I'll have a look in a bit after I've finished with these READMEs 11:57
kalkin- RabidGravy: “runtime application of the role” ← I understand that, but I'm not sure what you mean by → keyed on the same name … How do I do this with a role? (Btw no rush, I like the async nature of IRC ☺ ) 11:59
11:59 aborazmeh left
RabidGravy well 12:01
I think something like "role FooAuth does AuthMethod is auth-name('foo") { ... }" and when the server presents the Auth header with "foo" as a supported auth method you look for the AuthMethods you have which have an auth-name of "foo" 12:02
pr something 12:03
kalkin- RabidGravy: Why is it better then AuthMethod role having just a method auth-name which returns 'foo'? (I'm not arguing, just asking for better understanding of perl6) 12:04
RabidGravy I'm not sure it is better, it's just how I would do it :) 12:05
kalkin- hmm, on the other hand this way it's explicit in the code 12:06
RabidGravy it feels to me that it is meta-information about the auth type and should really be in the Meta Object rather than in the implementation
and that the auth framework should take care of the actual identification however it sees fit
kalkin- I see, thank you for your explanation 12:07
I think I need to refresh my memory on the “is” keyword.
kalkin- is going back to reading docs
RabidGravy an alternative to the above would be to parameterize the AuthMethod role with the nane which may be clearer 12:08
i.e. "role FooAuth does AuthMethod["foo"] { }"
some people get confused when "is" is repurposed for a trait application other than inheritance 12:09
timotimo when you have the "is auth-name" trait, you can register them globally 12:12
if you just hvae a .auth-name method, you'll have to rely on some code finding your role for you and calling that method
kalkin- timotimo: how would I list all is auth-name traits?
Should I iteratare over all available modules in CUR for that? 12:13
timotimo have a package-scoped hash and implement the auth-name trait to stuff it in there
or something like that, yeah
RabidGravy yeah, I'm using a similar technique in Sofa for defining "methods" to rest paths
kalkin- timotimo: I didn't want to provide it in Net::XMPP package, but wanted people to provide them from outside
so search in CUR 12:14
timotimo of course
yeah, search in CUR would be best unless you're fine with users of your package also pulling in the other auth mechanisms so they register themselves
.o( though i wonder how it interplays with precompilation when every module stuffs a class of their own into that array )
RabidGravy right that's ufo ridded from all of my modules :) 12:16
12:17 hankache joined
timotimo nice 12:17
kalkin- Btw there is no way currently to specify optional dependencies in META6?

timotimo of course
just take a parameter
RabidGravy re: searching the CUR for things that might implement something (such as an authentication method) can the Distribution object of an installed module have arbitrary attributes
timotimo in your trait_mod:<sasl-mech> 13:00
13:00 holli_ left
RabidGravy so e.g. one could have a "does" attribute in the META6 and that gets stored in the Distribution and then one could have a special CUR implementation that searched those values 13:01

RabidGravy github.com/jonathanstowe/Sofa/blob...fa/Item.pm has a "class trait" 13:04
13:09 smls joined
RabidGravy actually I could pull the stuff that implements that pattern out into a separate module 13:09
smls Am I misremebering, or did `prove t/` use work with Perl 6 .t files if they had an appropriate shebank line? 13:10
timotimo i seem to recall someone at some point saying that prove reads the shebang
smls It doesn't work for me anymore unless I explicitly specify `prove -e perl6 t/` 13:11
timotimo strange
RabidGravy wasn't someone working on a P6 prove? 13:12
kalkin- apropos separate modules On the one hand I don't want to end up with perl6 being the new JS with modules like leftpad, but on the other hand If I have some XMPP::SASL module containing MD5, SHA1, CRAM, wouldn't it make sense to package them as own distributions so people only use the dependencies they really need?
RabidGravy: doesn't zef bring it's own implementation? You can configure it in zef config.json to be used instead of prove
timotimo yeah, we have make spectest6
kalkin- The same issue I had with my License::Software package. I thought about packaging all the license templates on it's own, but then didn't do it just because it's to much effort 13:13
what's perl BP on this? How granular should distributions be? 13:14
RabidGravy It's really difficult to have a hard and fast rule on it 13:16
as in your SASL case, for example, the different modules may bring in a bunch of different dependencies and a strong case could be made for separating 13:17
likewise if there are multiple things where someone is only likely to ever want one then separate might be good 13:18
but otherwise and all other things being equal then they can all be in one distribution 13:19
kalkin- RabidGravy: The dependency issue is a good argument! 13:21
(for splitting in a bunch of modules)

pmurias kalkin-: having things like MD5 separated into modules seems better 14:57
people depending on XMPP::SASL just for MD5 doesn't seem good 14:58
RabidGravy gfldex, if you're going to do what I think you are, I would say roll your own and then spin it off into it's own module 14:59
so it keeps it's own internal stash of the attributes from ^attributes (probably only :local) and populates that with the de-sigllled names 15:01
so you have something like "Class::Associative" which is a role that turns any class into an Associative on its "public" attributes and then apply that to META6 and jobs a good 'un 15:02

cale2 The thing that confuses me the most about any programming language is organization. When/why to use modules/packages/classes 15:43
It doesn't help that Perl6 has modules, packages, classes, units, etc
jdv79 is there any reason the p6 weekly post ends up base64'd on pl6anet.org?
other entries are not 15:44
mst cale2: honestly, perl5 using 'just a package' for all those things wasn't less confusing
cale2 haskell and elixir are nice in that they only have modules and functions
mst also 'unit' is just a syntax thing
not an actual sort of organisation
cale2 mst: I read the docs on packaging in perl6 and it did not help in explaining when to use each one
I guess I just don't understand why you'd want so many different ways to group things 15:45
jdv79 stmuk_: ^^^ ?
mst cale2: there's only really two: modules, and classes 15:48
cale2: those are both types of package
cale2: a class is a thing designed for you to .new() and instantiate objects of
cale2: a module is a bag of subroutines
cale2 mst: there are packages though too
mst cale2: please read what I said again?
cale2 mst: They are types of package (which is a type). Got it. So packages do not exist in perl6. They are like virtual types 15:49
brokenchicken more like placeholders
mst cale2: 'package' is basically 'namespace'
brokenchicken m: package Foo {}; class Foo {} 15:50
camelia ( no output )
brokenchicken m: package Foo {}; role Foo {}
camelia ( no output )
mst cale2: docs.perl6.org/language/packages
cale2: Packages are nested namespaces of named program elements. Modules, classes, grammars, and others are types of packages.
cale2 mst: so because a module is a type of package, you could just use modules within modules within modules and never use the package keyword at all. 15:51
mst I'm not sure I've seen perl6 code that says 'package'
brokenchicken: ?
brokenchicken no idea about this stuff 15:52
mst I mean, have you ever seen a bare package/
brokenchicken Don't remember. I don't really code Perl 6 so almost no experience with it in the wild. 15:53
cale2 m: class Foo {}; say Foo.$?PACKAGE
camelia rakudo-moar 7f245f: OUTPUT«Cannot invoke this object (REPR: Uninstantiable; GLOBAL)␤ in block <unit> at <tmp> line 1␤␤»
mst brokenchicken: except for your small army of bots :P 15:54
brokenchicken yeah, except that :)
b2gills m: class Foo { say $?PACKAGE }; say $?PACKAGE # all variables with a ? twigil are compile time variables 15:56
camelia rakudo-moar 7f245f: OUTPUT«(Foo)␤(GLOBAL)␤»
cale2 "I don't really code Perl 6 so almost no experience with it in the wild." I think a lot of my confusion comes from not knowing the typical usage of things 15:57
I suppose a lot of that would clear up as books get released
brokenchicken cale2: one has already been: deeptext.media/perl6-at-a-glance 15:58
cale2 I saw that one. Print only though :/
brokenchicken mhm
RabidGravy mst, 'package' is used occassionally
cale2 And also, I'm more interested in "let's build like 5 full applications together in perl6" than the tiny example driven stuff 15:59
RabidGravy do feel free to make that then
cale2 Becuase the full applications would clear up packaging confusion, for example :)
RabidGravy: With the questions I've asked, would you really want me to guess my way through something like that? :P 16:00
RabidGravy of course, it's the best way to learn :) 16:01
mst, in places like github.com/jnthn/oo-monitors/blob/...s.pm6#L111 for example
mst ooh, when you really do want 'just a namespace'
RabidGravy yeah 16:02
mst why 'my' on the outer but not the inner? 16:03
also 'use experimental :macros' ... I didn't realise we'd started to get macros?
RabidGravy oh yeah, they've always been there
it's just the implementation isn't settled 16:04
mst ah
fair 'nuff 16:05
brokenchicken cale2: heh, yeah, "5 useless applications that doesn't really teach the language"?
I hated the Catalyst book for that. First 3rd is all about god damn tests and not the actual web framework 16:06
mst err, which one?
brokenchicken prolly old one
It was ages ago before I even knew of Mojolicious
mst there was a packt one, which was insane
and an apress one, which got into writing app code in ch.3 16:07
(IIRC 1 was intro and 2 was installing shit)
cale2 brokenchicken: For me, I'm at the point where I know how to program, but I am garbage at stuff like completing an actual application. So that stuff is actually helpful to me.
But yeah, actually writing tests is so passee.
gfldex I'm trying to implement subscripts with list keys on a custom class and utterly fail. Anybody done this successfully already? 16:08
mst the irony here is that if he's misremembering the way I suspect he is
the 'all about god damn tests' was actually the first chapter that I wrote
cale2 I saw a testing system for elixir where you describe the input and output data, then say how many tests you want, and it just lambasts your function that many times with various tests.
brokenchicken By the cover, I'd say it was the apress one...
mst and was written that way because I wrote the code for real first, then built the chapter around the commit log 16:09
yeah, so, *lots* of people have said that that was one of their favourite things about the book, in that it mirrored real development
brokenchicken hehe :)
mst I can only conclude you haven't learned to write enough tests yet
brokenchicken Well, it's worth noting I was drinking a lot back then :)
mst basically chapter 3 throws together a trivial app 16:10
then chapter 4 I added tests and refactored it to be extensible
but, yeah, mojolicious is way easier to get started with at the cost of being harder to maintain large scale apps in 16:12
cale2 mst: I would probably like your book if I was interested in p5 :) 16:13
mst grins
I'll take that as a compliment

brokenchicken buggable: eco HTTP::UserAgent
buggable brokenchicken, HTTP::UserAgent 'Web user agent': github.com/sergot/http-useragent
tadzik yep 21:37
cale2 I often use an API that requires you to paginate your calls. Like it only pulls 100 records at a time, so you have to hit it a lot in a row 21:38
When using Python's requests, I can use `with requests.session() as client:` and then re-use the cookie. It speeds up the requests a great deal 21:39
brokenchicken WWW::Mechanize:from<Perl5> is good for that. I haven't figured out a way to pass it regexes tho 21:40

agentzh any hints on debugging rakudo error messages like "Type check failed in binding to assignval; expected Array[EdgeLang::Stmt] but got Array[EdgeLang::Stmt]..."? 22:36
It's triggered by "use"ing a seemingly unrelated .pm6 module. 22:37

hmm, seems like memory corruptions or something. 23:09
now the typecheck failure shows up again.
it has nonderterminism. 23:10
should i run valgrind against it?
does rakudo/moarvm have special building flags for valgrind memcheck?
valgrind does not find invalid reads or invalid writes or use of uninitialized values on my side. 23:14
just a lot of definitely lost and possibly lost errors.
23:21 khw left
agentzh okay, got a "Syscall param write(buf) points to uninitialised byte(s)" error from valgrind when running rakudo: gist.github.com/agentzh/752af6b08e...c34f291164 23:25
not sure if it's helpful.
or should i ask in #moarvm instead?
brokenchicken Hm. That gives me a clue at laest. Both yours and the other errors are from the TWEAK method 23:26
oh that one's BUILD but here's TWEAK hmmm
agentzh valgrind takes forever to run. 23:28
the original perl6 finishes in 7+ sec.
so i guess valgrind would need 70+ sec.
agentzh waits.
i prepared a small example and cannot reproduce the issue. 23:29
alas.
just the real thing can.
23:30 vike joined
jnthn fiww, I think the uninitialized bytes issue there is pretty benign; some padding bytes at the end of a buffer are left as junk in a handleful of cases of bytecode generation. Since they never are read, it has no effect. Worth hunting down to quieten valgrind, though 23:31
23:32 cdg left
jnthn The Foo[Bar] didn't match Foo[Bar] issue is likely some kind of type interning failure 23:32

agentzh jnthn: how can i help debugging this issue? 23:34

agentzh now renaming my EdgeLang::Use to EdgeLang::UseStmt no longer helps. still the same error.
jnthn (Which will, I'm afraid, due to the nature of the bug, most likely involve multiple modules)
(Spread across multiple compilation units0
*)
agentzh yeah, if I comment out the line "use EdgeLang::Use;" from EdgeLang::Doc, then the typecheck error in EdgeLang::Doc disappears immediately. 23:36
jnthn Urgh :(
agentzh wondering if it has anything to do in the new Jan release that aims to support multiple version of the same name classes in a single vm. 23:37
maybe some how rakudo treats FanLang::Stmt as two different versions?
due to the loading orders in other classes' units?
agentzh tries the 2012.12 release of rakudo. 23:39
s/2012/2016/
brokenchicken That stuff works only for installed modules AFAUI
agentzh this is a showstopper for me.
brokenchicken the version.
agentzh brokenchicken: okay 23:40
i'm working on a large p6 project estimated 7K+ LOC (excluding comment lines and blank lines). 23:41
currently i'm at 1K+ LOC.
okay, the same error using rakudo 2016.12. 23:44
alas.
okay, i'll just remove the type constraint in that position and keep moving :) 23:45
i guess maybe the type constraint thing is not heavily exercised by most of p6 users yet.
i love it so i tend to use type constraints as much as i can. 23:46
