(No, I don't know how linking on OSX works...)

raydiak I suspect I've hit an impletementation wall, but is there any efficient way to store millions of values in memory under JVM? I tried hashes and arrays (swelled up to gigs for a few megs of actual data), tried buffers/compact arrays (don't seem to work yet), and am currently using a big string, which is extraordinarily slow to access 00:04
timotimo buffers should work actually 00:05
raydiak can you show me an example of one being initialized with values?

timotimo which one was the mutable one?
TimToady Buf, supposedly
jnthn Buf, but it's not yet mutable 00:12
Needs same work as native arrays do
timotimo Buf is supposed to, yeah :|
time to get that working ;)
TimToady
.oO("These Bufs are made for writin', and writin's what they do, and one of the days these Bufs are gonna write all over you...")
jnthn Yeah, it's pretty high on my post-Moar todo list :) 00:13

jnthn Which, given we're at 98% or so... :)

timotimo jnthn: yeah, anything in particular keeping us from merging?
jnthn timotimo: We need to merge nom into moar-support, and then make sure Parrot and JVM don't regress on any tests over nom. 00:15
That's mostly "run tests, compare output" in the best case.
And "fix stuff" in the worst.
I'd *like* to fix the OSX build before we merge.
But there's no real reason we need to I guess.
TimToady you've got 15 minutes :)

raydiak out of interest in the deeper things I don't understand yet, what is occupying all that memory for the boxed values? seems like the inflation was 2-3 orders of decimal magnitude in my case 00:33
jnthn raydiak: What types of values have you got? 00:34
raydiak jnthn: mostly numbers in the 0-1 range
00:35 dmol left, treehug88 left
jnthn OK, so a boxed Num will be object header + the actual value, and then if you have an Array then each of those is in a Scalar container 00:35
00:36 Pleiades` left
timotimo a list would be smaller then? 00:37
jnthn Yes, but how'd you mutate it? :)
well, bind of course 00:38
timotimo yup
jnthn Actualy, using an array but binding instead of assigning would be faster :)
timotimo use nqp::list_n instead

jnthn The answer when it's implemented will be "use my num @a" :)
timotimo maybe faster but less memory usage?
i would like that, yes 00:39
jnthn Well, my num @a will boil down to the same 6model REPR than nqp::list_n uses ;)
clsn Is a method supposed to have access to the private methods/attributes of an instance of the class other than self?
00:40 treehug88 joined
TimToady yes, which is why you have to use the $other!method syntax 00:40

clsn Great. I think my signature/parameter stuff is nearly ready to submit. Some notable holes still, some which require adding methods to Parameter, which I wasn't going to do. 00:58

raydiak in case anyone tries to do the too-many-numbers thing with jvm like I was talking about earlier, I'm having success with arrays (1 per row of a square dataset) of strings (though haven't tested the lists of native nums yet) 03:23
03:25 treehug88 joined
japhb Doesn't repr CArray work? Did someone try that? 03:26
raydiak I didn't...hadn't heard of CArray before 03:27
just got a stack overflow with a 1e7 list of uint1s, so I guess thats out 03:29
japhb Come to think of it, I don't remember if CArray works on JVM yet, may be parrot only right now. :-/
raydiak once bufs/compact arrays are writable, it'll be a moot point anyway...I've just been going in circles for a couple days, trying to figure out how to effectively buffer our output so I can move forward with concurrency 03:31
but rendering is done in hilbert(ish) order now, or will be when the concurrency branch is merged...so will also be able to add effective caching like you were talking about 03:41

moritz O(0.1) :-) 14:56
nwc10 I like FROGGS' suggestion. But I'm not an expert. Transforming return inside an if into an else block around the rest of the function sounds reasonable. But technically isn't this the same as "goto the final ; of the function and then fall off the end naturally?" 15:01
nwc10 guesses that structured programming is easier for subsequent optimiser steps to deal with
timotimo right. i don't know how to do that, though :) 15:02
also, i *think* i need to be aware of control exception catching blocks all around
15:04 thou joined
TimToady then they have a different final ; 15:06
but yeah, you can only replace return with a goto at the same level
and if that level is a routine rather than a block 15:07
timotimo sure
FROGGS and a proper routine, not a pointy
timotimo righto 15:08
TimToady pointies are counted as blocks

skids nwc10: generally optimizers are written to work on code that isn't just structured, but normalized to some form on which fancy properties hold true. 15:12
I don't think that form has been determined yet in this case, though :-) 15:13
timotimo that's true, the current optimizer transforms the code on the QAST level 15:14

lizmat TimToady: I feel that the number of values *returned* from a slice should determine whether a Parcel is returned or not 15:18
currently it is more or less determined by the slice specification: anything looking like it could return more than 1 element 15:19

lizmat I think it would be safe to have the number of returned values from a slice determine: if there is one element, then it should return that rather than a Parcel returning that element 15:21
since we can subscript [0] on everything anyway, the cases assuming a Parcel being returned, would still work
but maybe this should be specced also 15:22
or is it already?

grondilu hum... are state variables supposed to be associated to a 'do' block? 15:28
see: gist.github.com/grondilu/8438249 for why I ask this.
japhb jnthn: About? 15:30

camelia rakudo-parrot 4f66ce, rakudo-jvm 4f66ce: OUTPUT«1 2 3␤»
grondilu I guess not.
timotimo hm, can we figure out that the routine is an infix operator and the one before could have been meant to have () around it?
grondilu that would be nice indeed 15:32
FROGGS and then, what is "count + 3" supposed to mean? 15:34
skids lizmat: I do notice S02-types/autovivification.t referenced in the S09 autoviv section seems to require a \ to guarantee a Parcel 15:35
FROGGS count() + 3 or count(+3) ?
timotimo prefix operators may not have spaces between the op and the argument
FROGGS p: say - 3 15:36
camelia rakudo-parrot 4f66ce: OUTPUT«-3␤»
timotimo also, i'm asking that for making a better error mesasge, not for making that code work as-is
FROGGS I see
timotimo but you're right, i was wrong about the space requirement
FROGGS +3 for better error message :o)
timotimo haha :) 15:37
FROGGS + 3, even
timotimo postfix ops can have spaces before them, too?
grondilu still, it's bit silly to die when there is no other correct interpration. I mean, xx is not a prefix, so count(xx 3) does not mean anything. But count(+3) does. So I get that count + 3 could be an error, but not count xx 3 15:38
timotimo std: sub count { do ++state $ }; say count xx 3;
camelia std 09dda5b: OUTPUT«===SORRY!===␤Undeclared routine:␤ 'xx' used at line 1␤Check failed␤FAILED 00:01 126m␤»

preflex Consider it noted.
lizmat skids: I'm not sure where there is a test for Parcelness in S02-types/autovivification.t ?
the word Parcel does not even occur in that file?

dalek kudo-star-daily: dc902f0 | coke++ | log/ (5 files):
today (automated commit)
grondilu btw, I've noticed that there are very few warnings in Perl 6. Is that on purpose? Maybe expressions such as count xx 3 could trigger one.
[Coke] that just means you're doing it right.
FROGGS we will have warnings when we get lax mode I guess :o) 15:51
rindolf Hi all, why am I getting this with Niecza? pastie.org/8635970
FROGGS but atm the code is eitehr right and does not spit out warnings or it is wrong and dies
grondilu yeah, no warning in strict mode makes sense indeed. 15:52
PerlJam Perl 6 is just trending towards more black/white figure/ground/ solution/precipitate models ;)
[Coke] rindolf: looks right to me. what is surprising you?

japhb PerlJam: Perl 6 is the solution, and we're all the precipitate?
FROGGS rindolf: does that work for you? "Hello".substr(*-1)
[Coke] you ask for substr's that don't exist, so you get an undef Str; you concat that with "He", you get "He".
rindolf [Coke]: "Hello".substr(-1) should be "o".
FROGGS rindolf: no
[Coke] rindolf: nope. see FROGGS++ ^^
rindolf Like substr("Hello", -1) in Perl 5.
PerlJam rindolf: nope, see FROGGS
FROGGS p: "Hello".substr(-1)

rindolf [Coke], FROGGS , PerlJam : thanks.
FROGGS rindolf: you have to tell it that you want to wrap around
PerlJam Though maybe that's a case where a warning would have helped. "Warning: attempting to take substr() beyond the bounds of the string" or something 15:54
FROGGS well, rakudo does that 15:55
PerlJam oh, indeed it does
rakudo++
FROGGS and I could imagine that in a (certain?) lax mode it would automagically wrap around without the whatever-*
but I dunno how lax lax will be 15:56
PerlJam p5 mode? :)
FROGGS :o)
no problemo

PerlJam misses sorear
colomon feels guilty about not doing blog posts on this stuff. but then, colomon also feels guilty for not getting enough $work done and not doing enough for his family, too.
colomon also misses sorear++
PerlJam rindolf: want to take up the niecza mantle? :) 16:04
rindolf PerlJam: maybe. 16:06
japhb colomon: I've seen a lot of JVM out-of-stack-space reports recently. Seems like we need someone who knows Java well (a requirement that I do not fulfill) to figure out why that is happening so often. Barring explicit recursion, a Perl 6 implementation ought to be heap-heavy, not stack-heavy .... 16:07

erm s/where/when/
rindolf skids: neither is colors.
skids: but it lookups based on a string. 17:03
17:04 treehug88 joined
skids right but the string has numeric meaning, and depending on how fast rakudo can convert between substrings pulled out of the string and the desired index, might be faster than hashing. 17:05
rindolf skids: I use Niecza. 17:06
skids oh right. Might be worth a try doing a full array conversion, I dunno. Depends how fast the underlying constructs are, relatively. 17:09
e.g. when you do $seq.substr(*-1) that could involve a strlen, or might not, depending on the Str implementation. 17:11
Whereas an array almost certainly is implemented to store its own length.
Being able to precalc and premalloc the required space also might help, instead of letting things grow. 17:13

skids rindolf: if you can, from the input parameters, determine the size of a structure needed to fit the state stored during the calculation, it could be created and the values in it altered, rather than creating new objects on the fly. Further look at the code, probably not beneficial here. 18:06
rindolf skids: ah.
skids: I think part of the problem is that the Niecza program uses bigints all over the place, while in perl 5 they are machine integer limited to 64-bit. 18:07

Update cookbook/01strings/01-00introduction.pl

The code:
  <code>my $string = "1" ~ "1" + 10;</code>
will actually output "111" in Perl6.
Since in Perl5, "~" (actually ".") is the same precedence as "+", but in Perl6, numeric operations have higher precedence. So the "1" + 1 part will be evaluated first, giving "111" as the result.
Just a small modification here. :)		 21:52
