psch .tell ab5tract i'm unsure what classloading bit you're refering to. classloading happens for interop and "normal" runtime in different ways (BootJavaInterop.java and LibraryLoader.java respectively)
yoleaux 30 Jul 2015 15:23Z <ab6tract> psch: any clues on what might be borking module loading from non-SDK modules which also happen to be in CLASSPATH?
30 Jul 2015 16:05Z <ab6tract> psch: the module loader code for NQP... is there no native-Java way to find a class? can't we just s/::/./ and load the class? I know that CLASSPATH issues are notoriously common in Java, but still...
31 Jul 2015 16:20Z <ab5tract_> psch: what do you think of this approach to class loading? github.com/clojure/clojure/blob/41...oader.java
31 Jul 2015 16:22Z <ab5tract_> psch: I'm quite keen to help, but want to make sure there isn't some other consideration that made you eschew ClassLoader stuff entirely
psch: I'll pass your message to ab5tract.
Sgeo_ What 00:16
psch .tell ab5tract nqp commit d03863352f07a05fa68892997e417b62452cb34e simplifed the former significantly, and i suspect something similar should be possible for LibraryLoader.java too, but i haven't been able to dig in yet

yoleaux psch: I'll pass your message to ab5tract.
psch Sgeo_: a Junction decides between True and False, that's the two forks of the road it has in front of itself. mind, i'm *not* saying it's the best way to have them, just that it does make sense to me to hav'em like that 00:22
Sgeo_: a prototype exploring different behavior might be appreciated 00:23

psch yeah, what vendethiel++ said
Junctions aren't values
00:44 captain-adequate left 00:45 mr-foobar joined
psch and i'm aware that the distinction between values and possibilities is... weird 00:45
Sgeo_ Incidentally, why is * an Any?
leont Why would it be anything else?
Sgeo_ It changes the meaning of calls that aren't expecting it, the way Junctions do.. is it because it only does that at compile-time? 00:46
leont It doesn't do weird dispatch things like Junctions
vendethiel Sgeo_: * is a Whatever
psch the question is "why is Whatever below Any in the type hierarchy"?
Sgeo_ vendethiel, what psch said
vendethiel ah, okay :) 00:47
psch the default type for parameters is Any
and we want to be able to curry core functions
ShimmerFairy Sgeo_: I prefer to think of the Any type as being the parent of "Any"thing (Junctions don't count because they're a superposition of things, not a thing itself). 00:48
psch (that's the best reason i can think of at the moment, although there's probably better ones)
Sgeo_ psch, why would Whatever not being below Any hamper that? The currying process shouldn't require sending an actual Whatever to a function
ShimmerFairy, but a literal * in a function call for most functions isn't any thing, it's syntax sugar for a closure 00:49
m: sub f(Any $x) { say "f()"; }; say f(*); 00:50
camelia rakudo-moar 5d9306: OUTPUT«f()␤True␤»
Sgeo_ o.O
m: sub f($x) { say "f()"; }; say f(*);
camelia rakudo-moar 5d9306: OUTPUT«f()␤True␤»
vendethiel isn't sure what's surprising (knowing Whatever <: Any) 00:51
Sgeo_ I thought * was supposed to be syntax sugar for currying, this seems to limit when it can be used
vendethiel * stops at the method call boundary 00:52
leont It is, too
ShimmerFairy If * is used in an expression, it generates a WhateverCode
vendethiel so that a(* + 3) isn't \x => a(x + 3)
..and, like ShimmerFairy just said, if used as a term, it's a WhateverCode object 00:53
(used for stuff like *..*)
leont It's really a "make easy things easy" feature, taken to a new extreme
ShimmerFairy for example, the popular @a[*-1] actually passes a WhateverCode object that the subscripting op gives the size of the array as an argument
vendethiel m: multi infix:<..>(Whatever, Whatever){'vOv'}; multi infix:<..>(Int $a, Int $b){ "$a..$b" }; say 3..4; say *..*
camelia rakudo-moar 5d9306: OUTPUT«3..4␤vOv␤»
Sgeo_ But then f(1, *, 3) doesn't work so that isn't making that easy thing easy 00:54
psch Sgeo_: * is a shorthand for the *type* Whatever, which creeate... what ShimmerFairy++ said
vendethiel Sgeo_: again -- * stops at this level. it doesn't traverse calls.
psch oooh
~~ and * are special
ShimmerFairy m: my @a = 0,1,2,3; say @a[*/2]
camelia rakudo-moar 5d9306: OUTPUT«2␤»
psch because Whatever is special 00:55
ShimmerFairy ^ you can get the center element like that (or close to center for even-sized lists)
vendethiel again -- if * didn't stop at method calls, `a(* + 2)` would be `sub ($VAL) { a($VAL + 2) }` instead of what we currently have
leont Sgeo_: there are plenty of other ways to curry less simple cases
vendethiel s/method //
psch Sgeo_: * is *not* sugar for currying, it's creating a closure
(in my mind those are distinct)
Sgeo_ psch, sorry for inaccurate terminology
vendethiel [02:47] <psch> and we want to be able to curry core functions 00:56
psch because the close can be handled explicitely by the operator
Sgeo_ (On my part I mean)
vendethiel I think it's because of that :P
psch vendethiel: yeah, i seem to have messed up there :)
vendethiel++ # attentiveness
00:56 raiph left
skids Sgeo_: Whatever is Any specifically so you can do that. So you can make intellginet multis with their own Whatever candidates. See doc.perl6.org/type/WhateverCode 00:56
vendethiel I made an example of a multi with a Whatever-only candidate 3 minutes ago :) 00:57
ShimmerFairy m: sub foo(Int $a, Int $b) { $a * $b }; my &double = &foo.assuming(2); say double(4) # Sgeo_, here's how you can have currying in P6
camelia rakudo-moar 5d9306: OUTPUT«8␤»

vendethiel psch: yeah, it very well might
skids Sgeo: Yes but you'd have to explicitly Mu the parameter. 00:59
ShimmerFairy Sgeo_: the way I see it, you need a special reason to have something _not_ inherit from Any. That is, you need a special reason why someone can't use the "Any" type to pick your type up as part of the normal conception of "anything"
psch an Any-thing :)
if you want a Mu-thing you have to ask for it 01:00
Sgeo_ ShimmerFairy, the way I thought it worked seemed a sufficient reason
But it doesn't work that way, ok
psch Sgeo_: i'm still unclear on the way you thought it worked
Sgeo_ vendethiel18> again -- if * didn't stop at method calls, `a(* + 2)` would be `sub ($VAL) { a($VAL + 2) }` instead of what we currently have 01:01
psch Sgeo_: the one thing i distinctly picked up on is * being currying-sugar
Sgeo_ That way
ShimmerFairy Sgeo_: fair enough. The Whatever type is just to make a number of simple things convenient, we still have closures/pointy blocks/etc. for other cases.
vendethiel Sgeo_: it's the same with scala's _, say
(...though scala's has MUCH MORE COMPLEX rules)
ShimmerFairy e.g. what you want for foo(*) is not much more verbose as { foo($^a) } 01:02
psch so, what should < my $f = * + 2; say $f(2) > do instead of what it does..?
i'm a bit lost, i'll admit
ShimmerFairy It's not so much currying as a compact way of giving an expression to something and saying "this part can be Whatever". It allows @a[*-1] to be more expressive than @a[-1] , for example. 01:04
psch actually, i'm getting out of here again. i apparently got hung up on the wrong end of the discussion just now, which is a decent hint for "you're too tired for this stuff" :) 01:05
o/
ShimmerFairy o/
vendethiel Sgeo_: well, it'd be a bit unwieldly then. we'd need some kind of way to "stop it" 01:07
"don't cross THIS call!" - which would look ugly
TimToady so we limit the autopriming to unary and binary operators (counting method calls a funny postfix), and otherwise a function must decide for itself what it'll do with a Whatever argument 01:09
but really, the general case is handled with .assuming if you want partial function application 01:10
vendethiel checks for himself and sees he's speaking at the SPW2015 at 4pm
ShimmerFairy (or wrapping in closures and such if you need to do partial application out of order ☺) 01:11

RabidGravy not really
you need a proper content management system which is aware of the structure of the data to do things like that 07:43
Woodi but I mean some nice database for plain users. maybe directories are too universal, like lists :) 07:44

never used it, though
Woodi TEttinger: "more than 500k files", git do not support it ? what feature is responsible for that ?
TEttinger I have no clue.
RabidGravy but really, for structured files like music or images e.g. the thing that is managing them needs to understamd the structure, because for example a change in the metadata is different in principle to a change in the actual content 07:47
moritz Woodi: in git, each commit is basically a snapshot of the whole repo (though stored in a compressed format)
Woodi: so that means that with 500k files, meta data size really explodes 07:48
Woodi ah, I need to read sentences completly... plasticSCM claims to be fast

jdv79 hmm, just read the docs for URI - i exposing the match obj like that a good idea? 10:24

nine Is there a way to force a GC run yet? 10:24
jdv79 strikes me as unnecessary tight coupling 10:25

i think i say a nqp op a few days ago in here
nqp::force_gc() maybe 10:33

jdv79 is there a Maybe? 10:56
i have an attr that seems to want to be a subset of a str or Nil 10:57
timotimo yes, nqp::force_gc(), but it will only force the gc to start, not necessarily a major collection 10:58

jdv79 so how is /foo an absolute uri? 11:07
i find the URI module disturbing
dalek line-Perl5: eb00360 | (Stefan Seifert)++ | lib/Inline/Perl5.pm6:
Don't destroy P5 objects after the P5 interpreter was shut down

We run the default_perl5 object's DESTROY method unconditionally in the END. If after that the GC runs, it may DESTROY wrapped Perl 5 objects. If we try to decrement their reference count, we're in no-mans-land and may encounter undesireable effects like segfaults. So don't do that.
11:07 laouji joined
Woodi jdv79: it is not relative, "base" or something :) 11:15
also it's not URI at al ?
jdv79 yeah, i guess i'm mixing up uri and url 11:16

jdv79 $!is_absolute = ?($!path || $.scheme); # seems odd 11:19

jdv79 Woodi: the rfc seems a bit muddled about it actually 11:23
i think my intuituion is correct 11:24
there seems to be 3 forms of a uri relative reference; one of which is what i thought
in any case i believe URI is incorrect 11:25

dalek line-Perl5: 7cc2793 | (Stefan Seifert)++ | / (2 files):
Support passing named arguments to P6 class methods from P5

Named arguments can now be passed to Perl 6 class methods (e.g. constructors) using the v6::named function:
v6::invoke('MyClass', 'new', v6::named foo => 'bar', bar => 'baz');
All arguments before v6::named are considered positional:
v6::invoke('MyClass', 'do', "pos1", 2, "pos3", v6::named foo => 'bar');
11:40
nine If someone has an idea for something shorter than v6::named, yet as descriptive, I'm all ears.

jdv79 what is the p6 equiv of Moose's trigger on attr? 11:43
11:49 virtualsue left 11:51 virtualsue joined
jdv79 .tell RabidGravy maybe something like gist.github.com/jdv/73275880d42c7b952892 but still needs trigger mechanism to maintain other state. not to mention the module seems messy in general. 11:51
yoleaux jdv79: I'll pass your message to RabidGravy.
jdv79 i'm guessing a trigger is just a custom accessor that wraps and does its extra things 11:53
is there a way to get a more helpful type check failure error? 12:14
jnthn What makes you consider the one you got unhelpful? 12:15
They normally come with type got, type expected, what operation was going on, and where it happened...so if it's missing one of those something's up. 12:16

mst huh, is the doc.perl6.org/language/5to6 thing about unspace still a thing? 12:56
lining up multiple method calls vertically isn't allowed?
timotimo yeah, you need to put a \ before, because .foo is treated as "$_.foo" instead
mst so what's the idiomatic way to split method call chains over multiple lines? 12:57
leont I'm sure that's just a slang away :-p
timotimo sure, i think Tuxic does it like that 12:58
mst: put a \ at the end of the previous line
just like it's shown in the example in 5to6
mst huh 13:04
that's ... going to take some getting used to, I suspect
13:06 RabidGravy joined
mst or at least it's going to require me convincing my brain that actually perl6 is a Tcl dialect 13:07

camelia rakudo-moar 5d9306: OUTPUT«FOO␤»
mst jnthn: yeah, timotimo mentioned that and, honestly, I assumed it wasn't trivial by the fact that you hadn't done it already 13:10
since I'm sure I'm far from the first person to go 'wha?'
btw, we have a user over on irc.perl.org wondering: since most of the modules shipped with rakudo are .pm as an extension and don't have v6 13:11
how exactly is synhi supposed to know it's perl6 code rather than perl5 ?
sjn would love to see a "perl6-lint" or somesuch easily-available tool that could be used to hint about "Kwalitee" like issues like that. 13:13
jnthn mst: There are other heuristics (starts with a "module" declaration), but we probably need to do a better job of encouraging folks to do one of the two options you mentioned... Originally "the module starts with package without a block" was in the design docs as a sure-fire "this is Perl 5", but I suspect anything other than an extension or explicit v6 mention is fragile in the light of continued Perl 5 evolution. 13:16
13:18 brrt joined
mst right, I have at least one project where the .pm files mostly start with 'class Foo {' 13:18
admittedly, that's me using lib::with::preamble to inject Moops implicitly via App::MyPerl
which is hardly a central use of perl5
13:19 rindolf left
jnthn Aye, but if p5-mop gets done and gets in, it might make class Foo { ... } a regular thing in Perl 5 too 13:19
Anyway, I'm fine with making sure the things in lib/ in Rakudo (all 4 or so of them...) get fixed up to have one of the two
