[Coke] masak: is there a way to use macros to conditionally add an attribute to a class? 00:03
timotimo I would use the MOP for that, honestly :( 00:04
masak same.

masak [Coke]: it would be easier to discuss around a piece of code, I think. 00:04
[Coke] then I'll just reply to the list and you can take it from there. :)

japhb_ [Coke]: What's the r-m % currently? 00:20
raydiak and does it crunch numbers faster than JVM? :) 00:21
japhb_ raydiak, For native types in heavy loops, I'd be surprised if it did -- the JVM jit is really good at that. 00:22
raydiak I won't hold my breath, then...but not using native types
japhb_ And Moar doesn't have a jit yet. It needs to be working fully correctly before we start turning broken code into ASM ops. ;-) 00:23
OK, then my #1 optimization tip will probably be: "native types in arrays, not HLL types in hashes"
timotimo i was thinking maybe we could get a specialized low-level hash for strings going? 00:24
as in string keys to string values
raydiak when I tried to use native types a couple months ago, I ran into NYI roadblocks
japhb_ timotimo: What's the use case for specializing just that particular mapping? 00:25
timotimo our native type arrays are, i believe, not thoroughly awesome yet
japhb_: not that sure
we may have some of those internally
perhaps it makes more sense to specialize just string keys
and make trie-like structures or red-black-trees with those
japhb_ BTW, did all the known bugs of Rakudo pre-allocating very large arrays get fixed? 00:26
timotimo i don't think i know about those? 00:27
raydiak r: my int $a = 1; my int $b = 2; say ($a+$b).perl;
camelia rakudo-parrot e32249, rakudo-jvm e32249: OUTPUT«3␤»
timotimo there was a fix to the for iterator to not create huge arrays all the time
japhb_ The 100_000 length array one was the first example I remember.
But then there was discussion of reducing the default size of hashes to 4 (or 8?) entries too, and some other such that I forget the details of. 00:28
There's something for your GC torture, nwc10: Check how many words (or even bytes) in fromspace are 0. That would give us a rough idea of how much we're overallocating for our actual usage. 00:30
That plus a histogram of allocation request sizes would go a long way.
Hmmm, IIRC MoarVM's GC is type-exact -- so we can actually have a histogram of allocated structures as well. 00:31
[Coke] still waiting for today's jvm run to finish, japhb_ 00:34
JVM is at S32-str/ords.t 00:35
japhb_ [Coke], Ah OK, gotcha. Thought my question just got lost in the chaos. :-)
timotimo hm. actually, we could build a python plugin to gdb to create the histogram 00:40

timotimo rakudo.moarvm may take much longer for stage mast than rakudo.parrot does for stage post/pir, but after that follows a compilation process to .pbc that takes quite a while, too 01:05
so it may not even be terribly surprising that moar takes so long for that part

japhb raydiak: There's a syntax error in lib/Pray/Geometry/Object.pm6 on line 197 in the version you pushed: 'is copy' shouldn't be used for a call (as opposed to declaration). I'm assuming you have that fixed locally and forgot to push it? :-) 01:24
timotimo i'm beginning to think that a whitelisting compiler that makes sure that no harmful code is executed would be a good thing to have included in rakudo itself 01:26
to allow things like safely checking the syntax of code, for example

Quom So, I've never been able to compile Rakudo on MoarVM. I get the error: Undefined symbols for architecture x86_64:␤ "_MVM_6model_add_container_config", referenced from:␤ _Rakudo_containers_setup in container.o… 03:07
on Mac OS X 10.9.1, nqp passes all spectests 03:08
*nqp-m
BenGoldberg I think I might have missed part of the discussion... are you cross-compiling Rakudo, with MoarVM as the target, or (if you've already cross-compiled) trying to bootstrap using the Rakudo that you've already built on M? 03:10
Quom ....
03:10 ssutch joined
BenGoldberg Or am I just confused? 03:11
Quom I don't know.
[Coke] BenGoldberg: rakudo-moar is working for most people. no cross compiling.
BenGoldberg Oh, ok :)
BenGoldberg was confused ;) 03:12
Quom I got the error using my usual seperate directories `make install`ing everything to /usr/local, and eventually tried making a new rakudo directory in a different location and simply `--gen-moar`ing 03:13
s:3st/e/a/
[Coke] Quom: are you using hte moar-support branch? 03:14
Quom yes
[Coke] (of rakudo)
Quom yup
[Coke] with --gen-nqp=master and --gen-moar=master --backends=moar ? 03:15
Quom I can try that
[Coke] otherwise you might be settling for an older version of nqp/master - we're not quite there with making sure we have the right deps. 03:16
Quom I simply used `perl Configure.pl --backends=moar --gen-moar` the last time I tried
[Coke] er, of nqp/moar
Quom okay, but it wasn't working using sister directories for each of the projects that were all updated to lastest commit whenever I would try 03:17
[Coke] ah. 03:18
then probably a real bug.

camelia rakudo-parrot e32249: OUTPUT«OH HAI␤»
masak this situation is very close to the one finanalyst found with macros. 13:39
but unlike it, it Does The Right Thing (from the user's perspective).
let's step through it in slow motion:
1. Role R is created. As part of that, R.foo gets an OUTER chain. Pointing to the static mainline, because that's all that exists at that point. so $x is the static version. 13:40
2. Class C composes in R. $x in .foo is still bound wrongly.
3. Program runtime begins.
4. <MAGIC HAPPENS> 13:41
5. The (live/runtime) $x is assigned "OH HAI"
6. C.new.foo is called, and somehow it gets ahold of the *live* $x
kinda similar, right? 13:42
roles have a step 4, and macros (currently) don't.

1 and 4 in particular
nwc10 yes, the Python 2.x approach is messy, as it causes runtime, data-driven exceptions 16:29
and I suspect that (4) is the wrong solution to a valid problem
(or a pair of valid problems - that OS interfaces might return filenames, etc, that aren't in the encoding that you thought you were dealing with 16:30

nwc10 and that one about headers not being in ISO-8859-1, as per various specs, but in UTF-8) 16:30

my refinement of my code makes almost all test failures go away \o/
nwc10 agree, oh yay
oh, actual yay
not scarcasm yay
yay \o/
timotimo actually. the remaining test failures came from files cluttering my rakudo folder 16:32
so all i'm left with is passing TODOs and no failures \o/
arnsholt Cool!
timotimo on that topic, S32-io/copy.t uses the deprecated IO::Handle.copy method 16:33
i think perl6 could use a module just like python's "webbrowser" or "browser" or what it's called 16:48

FROGGS meh
unclefester2: pack takes numbers and produces a buf
p: say pack "S*", 42
camelia rakudo-parrot e5268b: OUTPUT«Buf:0x<2a 00>␤»
unclefester2 the UTF-16 encoding of the string should return an a buf array of 16 bit numbers 22:36
