llfourn_ my point is that it works with everything except with in statement mod form
psch reads up what "it" actually is
Zoffix what's "everything"? I see only an if statement 10:19
llfourn_ err yeah I guess that is everything
psch m: my $a = "foo"; ($_ given $a) = "bar"

psch geez all these features :P
llfourn_ Zoffix: ok. I think $_ should always be := to the topic's container. I'll leave classification up to you :) 10:23
psch yeah, implicit topicalization should always be <-> 10:24

synopsebot6 Link: design.perl6.org/S04.html#line_583
psch well, a bit higher up, like 575 or something 10:29
and, well, <-> is apparently 'is rw', so topicalization should always be rw, if we take 'for' as reference 10:30
llfourn_ m: { say $_ } for 1,2,3 # hih this works?
camelia rakudo-moar e9409c: OUTPUT«1␤2␤3␤»
llfourn_ didn't know if you statement mod a block it runs it
Zoffix "for and given privately temporize the current value of $_ for the left side of the statement and restore the original value at loop exit:"
Maybe that's why the `given` worked above but `with` and `andthen` didn't ¯\_(ツ)_/¯ 10:31
llfourn_ ('if' works too)
psch doesn't that just concern the value of $_ outside of the statement mod?

i think :/
...i'm actually trying about how to map our built-in types sensibly to java types right now :S
*trying to think
just to explain some confusion, maybe vOv 10:43
it's really annoying, honestly 10:46
considering we can have any kind of type as array or parameterized List on the Java side as parameter
i mean, it's not hard to imagine that [1,2,3] doesn't dispatch to int[], because we already don't do that on the Perl 6 side 10:47
but does 'my Int @a = 1,2,3' dispatch to 'List<Integer>' and int[]?
or only one of them..?
otoh, our Int is more Long, and doesn't that mean only 'my int32 @a' should dispatch to int[]..? >_> 10:48

MasterDuke ha, same here 11:34
should i stick [@LARRY] on it? 11:35
nine Is there any way at all to override stringification or string interpolation in a dynamic scope? I don't care how hacky.
timotimo in a *dynamic* scope, oh boy 11:36
lizmat MasterDuke: sounds like a plan
timotimo interpolation is just turned into a series of strings and ~ operators by the compiler
dogbert17 o/ any ideas about RT #129321
synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=129321
timotimo so you can't differentiate "foo $bar baz" from "foo " ~ $bar ~ " baz" any more when the compiler is done 11:37
nine So if I could somehow override ~, I'd have a chance?
lizmat nine: dynamically ???
nine What I actually want to try is just for a lightning talk hack together a little SQL parser that eats "where foo = $foo" and can turn it into something like {foo => $foo} to feed it into DBIX::Class 11:38
Just for show
gfldex nine: overloading ~ works if you introduce a new type (SQLString or somesuch) 11:40
timotimo you can wrap infix:<~>

MasterDuke it could just serve as a reference for a different PR that just does the ones that are wanted? 12:23

lizmat (accessing a @a[Bool] is now 20x slower than an @a array)
jnthn But yeah, special cases for 1/2/3 was The Idea, so no objects.
lizmat which ops should I be looking at ?
jnthn There's some 2d and 3d ops 14:03
I'm pretty sure they are covered by tests in the NQP repo
lizmat no special 1d ops?
ok, will look
timotimo github.com/MoarVM/MoarVM/blob/mast...plist#L706
jnthn The 1d ops are just called atpos and bindpos ;)
timotimo 2d, 3d, and nd
jnthn (e.g. they're the exact same ops you'd use on an unshaped array)
lizmat jnthn: yes, but upper bounds would need to be checked "manually" right ?
jnthn No 14:04
lizmat ah ?
jnthn The upper bound checking is enforced by the REPR
The atpos ops are polymorphic
So on a VMArray they'll have resize semantics
And on a MultiDimArray will throw on out-of-bounds 14:05
lizmat so on array can be multidim even with 1 dim :-)
jnthn Yes
MultiDim really means FixedDim I guess :)
lizmat and it will get bounds checking thrown in
ok
jnthn Apparently the person naming it was a bit dim ;) 14:06
timotimo and we'll be able to kick out bounds checking in some cases when we reach spesh and jit stages

lizmat who knows :-) 14:10
jnthn Though I'm hugely tempted to just concentrate on fixing Proc::Async up well and then re-impelenting the Proc class using Proc::Async :P
lizmat sounds like a plan, fwiw :-)
ugexe fwiw `reduce { $a + $b } ()` in perl5 returns undef, which is more useful than an exception because you can chain together grep/map/reduce without worrying about the number of elements before the reduce 14:11
jnthn Since we actually use the very same libuv APIs in both
lizmat as long as we don't lose the JVM completely :-)
jnthn I think the JVM supports Proc::Async?
MetaZoffix
.oO( but Proc::Async.start returns a Proc... )
jnthn Will have to check...
MetaZoffix Procseption
ugexe jvm doesnt have proc async 14:12
MetaZoffix well, its Promise does :)
jnthn ugexe: Yes, but in Perl 5 there's no option to design it to take advantage of multi-dispatch to specify what the base value will be
And you can still write it as -> $a?, $b? { DTRT here }
jnthn returns to $day-off :-) 14:15

timotimo "bring your butterfly to work day" is the perfect opportunity to have her tested! 14:21
mst ugexe: I would write that as 'reduce { $a + $b } 0, ...' in perl5 tbh 14:24
yoleaux2 21 Sep 2016 21:19Z <ZoffixMobile> mst: exactly 1 year ago you told me in magnet #perl to poke you in a year about binary package installer for CPAN :)
mst MetaZoffix: and, indeed, my work is grinding slowly along
but it wasn't going to be ready for YAPC::EU this year so I shaved the alien6 yak instead
timotimo MetaZoffix: maybe i didn't read carefully enough, but it says nowhere that the coverage report is far from infallible 14:26
MetaZoffix mst++
timotimo: I mention it in the first sentence here: ds3:3000/post/Perl-6-Core-Hacking-C...tpsreports and here mention they need improvement: ds3:3000/post/Perl-6-Core-Hacking-C...ettercover 14:27
timotimo oh!
MetaZoffix oops, wrong domain. But you get the idea :)
timotimo ah
yes, of course
man, i'm not feeling awake at all
MetaZoffix Coffee! 14:28
ugexe mst: but if you want to chain map/grep/reduce would you still do `reduce { $a + $b } 0, grep { $_ > 10 } (1..9)` 14:32
mst ugexe: probably not, but I fatalize undef warnings so I'd have to end up with that code before it actually passed its tests 14:34
i.e. "I wouldn't, to begin with, but that would be a bug"
lizmat afk& 14:36
ggoebel How likely is it that the JVM GLR won't have happened by the time the next Google Summer of Code rolls around? 15:29
nine The results of my SQL experimentation: niner.name/talks/DBIC%20in%20Perl%2...revisited/
t/test.pl6 probably demonstrates what it's about :)
ggoebel If not, how likely that the JVM GLR would be a viable/submitted/accepted SoC project? 15:31
Kolin_ ggoebel: so when is the next SoC? 15:55
TimToady um, next S 15:56

camelia rakudo-jvm cd19db, rakudo-moar fef365: OUTPUT«((a b c) (a b c))␤»
TimToady I'm not sure JVM GLR is quite a thing, since most of the GLR work was at the rakudo and nqp levels, what remains might just be a smattering of bugs
Kolin_ Yeah
nine And a lot of it is probably just looking at the workarounds that were done and figure out what the real fix would be like 15:58
Kolin_ What are some good programming books to read? To become better at Rakudo/NQP/MoarVM hacking? 16:09
ggoebel Kolin_: The Google SoC timeline for 2016: developers.google.com/open-source/gsoc/timeline 16:11
SoC is announced in October. Organizations begin submitting applications in February. Applicants apply in March. Accepted Proposals/Students announced in April. Work runs from May to August with various checkpoints and deadlines. Results of SoC Projects are reported at the end of August 16:13
Kolin_ ggoebel: right, but see what others said about. JVM GLR isn't really a thing
stmuk Kolin_: its more online resources (perl6.party blog etc.) and just trying it
Kolin_ Surely there's more to it. 16:14
ggoebel TimToady: Perhaps I'm mistaking, but I've had the impression that Rakudo on JVM hasn't been a first class citizen since the GLR... 16:15
s/mistaking/mistaken/
Kolin_ ggoebel: right, but I don't think it's GLR itself that's the issue. It's just after GLR it hasn't kept up
ggoebel: you can run the stresstest and see what tests are failing to see its current state. Rakudo on MoarVM passes all of them
ggoebel: git clone github.com/rakudo/rakudo/; cd rakudo; perl Configure.pl --gen-nqp --backends=jvm; make; make test; make install; TEST_JOBS=8 make stresstest; 16:16
ggoebel Kolin_: I got the impression that JVM not being kept up coincided with the GLR
Kolin_ ggoebel: it also coinsided with frantic efforts to make something releasable for Christmas 16:17
(if you also want to run Perl5 tests, install Inline::Perl5 per step 12 on github.com/rakudo/rakudo/blob/nom/..._guide.pod ) 16:18
nine Kolin_: TimToady already stated that a 6.c release without JVM is ok back at his FOSDEM talk in February 2015
ggoebel: ^^^
TimToady it would be nice if we could catchup the JVM by 6.d, which is hopefully before next summer 16:19
ggoebel TimToady: okay. One of my offspring is a CS Major who might be interested in a Perl6 JVM SoC project if "it would be nice" doesn't turn out to be practical by next Summer. 16:22
phenny: seen colomon? 16:27
hmm
Kolin_ .seen colomon
yoleaux2 I haven't seen colomon around.

ggoebel So the way to figure out the roadmap to bring JVM up to snuff would be to run the stress test, pick a bug, lather, rinse, and repeat?

Fix GLOBAL symbol clash re-compiling due to a repo change

After we detected that we need to re-compile a module because one of its dependencies changed, we sometimes turned out to try loading the old version again due to a stale precomp unit cache. However the module would load just fine on the next try.
The reason was that we invalidated the cache of a different precomp store object than what we used for loading precomp files as the repository implementations created different objects for the precomp store list (used for loading) and the accessors of their own store (used for storing).		 20:19
