diakopter timeout on 1690? 00:18
00:18 molaf left
diakopter (1691 I mean) 00:18
Tene phenny: ask jnthn if I should expect to need to write my own repr for cardinal, or if I should be able to get by on P6opaque at first. 00:21
phenny Tene: I'll pass that on when jnthn is around.
Tene phenny: thanks; you're very helpful
donri p6opaque mo?

Tene donri: The Perl 6 specification includes representation polymorphism. You should be able to use objects mostly without caring about how they're actually represented in memory, and various ways in which you should be able to indicate what sort of memory representation you want. P6opaque is the primary representation used for objects in the nom refactor of rakudo. 00:27
donri: The traditional example of representation polymorphism is packing of native types. If you have "my int @foo[10];", where the lowercase "int" indicates a native type instead of the Perl 6 class Int, you should be able to represent the storage of that array with a contiguous hunk of memory the length of 10 native ints 00:29
00:29 jtbraun1 left
Tene Instead of having a separate container, attributes, separate storage, etc. for each int object 00:29
donri: Similarly, P6object should be able to inline attributes of native types in arbitrary classes. 00:30
donri: Does that sufficiently satisfy your curiosity? 00:32
donri: I'm trying to use 6model (the object model being developed for the nom refactor of rakudo) for Cardinal, the Ruby compiler that treed and I have worked on. 00:33
donri but do you get an int or an Int?
Tene donri: I'm sorry? I need more context for that question.
donri my int @foo
Tene Right, but what about it? That's an array that stores ints. 00:34
donri i guess that's what you meant with the "use without caring about repr"
that you can use these ints as Ints 00:35
but why would Int need more storage than ints?
diakopter b/c the runtime needs to know the type of scalars that are boxed 00:37
Tene donri: a few things... Int is unsized, and can hold arbitrarily-large values, etc.
donri ah 00:38
00:38 envi joined, rdesfo joined
Tene Using int as a type annotation tells Perl 6 that it can do optimization to hold only that much, and that it's a value type, so the details can all be optimized out, etc. 00:38

benabik You just have to remember not to rebase anything you've pushed out. That's not so friendly. 14:43

14:43 bluescreen left
donri mathw: not giving up on perl 6, i know rakudo and parrot haven't had much optimizations done and this is an expensive problem 14:44
mathw :)
benabik JimmyZ: Because rebasing is very evil for already pushed branches.
JimmyZ: Although you can make it default for you: 'git config --global branch.autosetuprebase true' 14:45
JimmyZ: (Leaving off --global will make it default only for the current repo.)
mathw Because git supports many many workflows, and some of them break horribly if you rebase in the wrong places
JimmyZ can't automatic rebase when it's needed? 14:46
benabik Git defaults to the safe option. Altering history is cheating and is not guaranteed to give you back exactly what you put in. 14:47
Also, if anyone has made commits on top of the ones you're rebasing, they can have a real problem syncing back up. 14:49

nice! people took up the mini-challenge :) 20:50
colomon++
tadzik question: Rakudo is written in Perl 6. What happens when we lose the first compiler? :) 20:53
masak we'll just use the second? 20:54
tadzik I mean, when we run out of the working compilers, what will we do?
20:54 jferrero joined
masak the question seems to ignore that the compilers usually build themselves via bootstrapping from smaller languages such as nqp. 20:55
Tene Anyone know if there's a specific reason that the spec doesn't define some of the more-obvious unicode math ops, like ≠ ?
I mean, it's obviously not completely adverse to unicode, what with «» etc.
masak Tene: the spec doesn't define any ops outside of latin-1.
20:56 mtk left
tadzik masak: so when Rakudo builds, it first builds some part of itself using nqp, and then builds the Rakudo-Rakudo? 20:56
masak yes.
similarly, nqp-rx bootstraps itself from PGE, which is written in PIR. 20:57
so it's something like Parrot -> PIR/IMCC -> PGE -> nqp/rx -> Rakudo -> Rakudo's setting. 20:58
hm, the first 'Rakudo' could say 'Rakudo grammar/actions' 20:59
[Coke] masak: It's all so simple!
masak [Coke]: :)
21:00 Axius left
masak diakopter: huh. I didn't look at the Java solution before posting my challenge, but it's nice to see it (and your solution) corresponds to my idea. 21:02
nice premature optimization on the bitshift :P
Tene masak: these days, nqp bootstraps itself with nqp 21:04
21:04 mtk joined
Tene masak: there's a compiled-to-pir version of nqp that's built and shipped with parrot, the stage0 compiler 21:04
masak right. that's the one I was thinking of. 21:07
I'm actually not entirely sure what the role of the stage0 compiler is. I just assumed it was used to build nqp-rx the first time around. 21:08
I meant to start writing the p5 post tonight, but I'm too exhausted after $dayjob. hopefully tomorrow night. 21:09
colomon: your solution uses lazy lists, whereas the mini-challenge was to write a version without them. did I miss something? :) 21:12
colomon moritz_: (re roast commit bit for jdhore) I always forget I can do that!
masak: A) was ignoring your challenge
masak: B) actually, my core code does NOT use lazy lists.
jdhore :D
colomon The sorted-merge function takes care to allow lazy lists, but the hamming function never uses them. 21:13
masak colomon: oh, I saw gather/take and assumed it did. sorry 'bout that :)

colomon I wouldn't be surprised if it's not permitted, actually.
Tene Why? 21:22
moritz_ well, it can short-circuit as soon as the answer is determined
Tene Exactly why I expected it to work lazily, moritz
moritz_ ie at least one True for an any() junction, at least one false for a none() junction etc.

donaldh I've simplified the example. It was based on: sub sqlite3_open( Str $filename, OpaquePointer $ppDB is rw ) 23:05
I'm trying to extend Zavolaj to initialize out parameters, i.e. those marked is rw. 23:07

donri donaldh: can't you set a default or make optional? 23:09
23:10 Trashlord joined 23:11 kst` is now known as kst
donri but i'd think you'd usually write a wrapper api on top of the nativecalls 23:11
donaldh Currently I have to do this: my $db = pir::new__Ps('UnManagedStruct'); my $status = sqlite3_open( "test.db", $db ); 23:12
I want to avoid having to initialize $db by embedding that behaviour in Zavolaj. 23:13
donri: github.com/jnthn/zavolaj/
donri oh zavolaj *is* nativecall? 23:16
i thought it was sqlite3 via nativecall
donaldh Yes.
23:16 stifynsemons joined
donri perl6advent.wordpress.com/2010/12/1...om-perl-6/ 23:16
suggests wrapper api
donaldh perhaps that's the only viable approach. 23:20
donri i think the whole point of the "is native" subs is to represent the functions in natural perl 23:21
it needs that information to even work, at least without .h files
23:23 jaldhar left
donaldh Yes, that's right. "is native" is a multi trait that is implemented to do some high magic. 23:23
23:23 jaldhar joined
donaldh I have extended it to understand "is rw" parameters and generate the necessary NCI call signatures. 23:24
I would like it to 'autovivify' the "is rw" out parameters, but all I have to work with is an immutable capture. 23:26
