colomon (the reason I ask is because it seems to me this scheme requires the topmost version of .perl to somehow define anonymous variables that can be used in lower levels -- which again seems like a significant overhead to the .perl implementor.) 00:05
TimToady all you need is a lexical scope to contain any variables declared en passant 00:07
sjohnson chess! 00:08
TimToady temp varnames could be stored in the seen hash if the can't be regenerated from self.WHICH
as for threading, that's why contextual variables aren't p5ish local vars

dalek p-rx/nom: 5ab91d8 | jonathan++ | src/stage0/ (3 files):
Update the bootstrap to get method cache into the stage 0.
 00:20
p-rx/nom: 9dcdea6 | jonathan++ | src/metamodel/reprs/P6opaque. (2 files):
A refactor of P6opaque to start to prepare the way for natively typed attributes. Along the way, this slashes a memory allocation per object instantiation, meaning that it's now just the PMC header and the object body. Given there's no RPA for attributes any more, this boils down to half the number of allocations and half the number of GCables for 6model objects compared to current Parrot objects.

bucky sorry for this faq question but does the shell in Parrot 3.0.0 support readline? 01:00
i guess it can because configure has an --without-readline option... tnx 01:03

sorear bucky: The trick is that /usr/include/readline.h has to be available *when you run Configure*. 01:24
bucky: This also applies to libicu, if you want Unicode to work properly
lue In a file, the result is 7. It's amazing that I can break the semicolon in Perl 6 (of course, I'd afterward have to define a new way of separating statements)

bucky edit myconfig and add -O2 to ccflags=' ? 01:35
sorear not sure offhand 01:40
but myconfig is almost certainly wrong
you want some combination of gen parrot stuff and --optimize
actually doesn't gen-parrot use --optimize by default?
flussence on mine at least, it seems to take the CFLAGS setting from perl5. 01:46
sorear poor interpretation of profiling data suggests that 3/4 of the retained set of niecza when compiling itself is lists 01:58
non-list objects are underrepresented to a confusing degree - what's IN the lists? 01:59

mathw morning jnthn and masak 11:12
masak heh. late start today. I guess I got carried away reviewing p1 submissions yesterday :) 11:13
moritz_ masak: how did you like the solutions so far? 11:17
jnthn masak: lol, I only just got up too :) 11:18
masak moritz_: they are generally of high quality. not much to complain about, really.
moritz_: I won't spoil the blog post entirely, but among the p1 ones, there are three which do DP, one that is correct but slow, and one that is fast but wrong. 11:19
11:20 cogno left
moritz_
.oO( it's easy to get the wrong result in O(1) )
 11:22
masak this one does it in linear time. 11:23
jnthn Heh. I shoulda submitted say "OMG GIRAFFE!"; for all of them, then claimed that I had the fastest program for every problem.
masak the correct-but slow one grows as O( n! )
arnsholt The brute-force approach. Always a classic =)
masak jnthn: you could've. but you wouldn't have won. :)
arnsholt I kinda want to figure out how the O(n log n) algorithm for matrix chain works though 11:24
masak arnsholt: do you have an URL for that one?
arnsholt Sounded kinda nifty, based on triangulation of regular polygons, apparently
masak I think I'd like to throw it into the blog post.
huh? polygons? in p1? :) 11:25
arnsholt I got the reference from en.wikipedia.org/wiki/Matrix_chain_..._Algorithm
ftp://reports.stanford.edu/pub/cstr/reports/cs/tr/81/875/CS-TR-81-875.pdf
Yeah, polygons apparently =)
moritz_ I figured it was over my head :-)
masak arnsholt: thanks. 11:26
arnsholt moritz_: I looked a bit at the paper and decided I didn't have time to figure it out 11:27
After all, I need some time to write my master's thesis as well ;)

arnsholt: hm. I'll check.
arnsholt: the former. 13:20
had there been external files in any of the submissions, I'd have to write a slightly more involved site renderer. 13:21
arnsholt Good thing I blew the deadline then, since three out of four of my solutions had a lib/ with a module file in it =) 13:22
masak I'd had happily written a bit of extra code for your sake :)
I'm still thinking of the best way to mention you come p4.
arnsholt That's nice to hear ^_^
JimmyZ couldn't visit apache.org. 13:23
flussence yep, down for me too 13:24
and the subdomains, apparently...
arnsholt masak: I'd suggest putting it in the general discussion of the solution you were looking for, I think
JimmyZ yes 13:25
masak arnsholt: good idea.
arnsholt: but I want to link to the code, too.
13:25 Chillance joined
flussence (that's a bit of a shocker, the site of a webserver going down :) 13:25
masak maybe I'll just upload it manually.
arnsholt That'll work. Or you can link to the URL I posted a few days ago. It's on my uni web area, so it's nice and available 13:26
You can't make notes on that though, obviously
masak hm. more thinking is required. 13:27
colomon Is "exit say" actually a good idiom? I mean, it looks pretty, but if there is a problem with the say it will return the wrong exit value, no?
jnthn colomon: It may be too cute. I had mixed feelings when I saw it. :) 13:28
masak it's probably not a good idea for bigger programs.
jnthn It is going to aways give a non-zero exit code
masak but the fact remains that &say currently always returns 1
jnthn So in that sense it's "good enough" 13:29
masak right.

but still interested
jnthn prashant_: Perl 5 is widely used in production today, mature, and has plenty of exciting stuff going on. Perl 6 is in development, not widely used yet, and also has lots of ways to get involved. Since things are at an earlier stage there's a lot more gaps to be filled.
shortcircuit Hm.
Ways you might help. 13:54
prashant_ hmm
jnthn prashant_: Really, it's finding something you like doing and doing it. :) There's some ideas on www.perl6.org/getting-started/involved
shortcircuit Oh, cool. There's a page for that? :)
BTW, what's the Perl 6 analog for CPAN?
mathw Of course

jnthn pmichaud: If you have a moment, I'd like to get your thoughts on how to handle nqp-rx => nqp-rx/nom migration issues. 19:42
pmichaud: As you mentioned before, there's a sense in which it's a "different product".
pmichaud: I know it won't (can't) be a seamless transition, so replacing the parrot-nqp.exe in the Parrot repo with the "new nqp" is almost certainly not going to work out. 19:43
I think it'll have to be more like what we did before with nqp => nqp-rx.
pmichaud we can't replace parrot-nqp.exe with a new one because... we don't have the object model stuff in parrot to support it? 19:44
19:44 bluescreen joined
jnthn Kinda, yeah. 19:44
Also some semantic mis-matches.
The multiple dispatch works wiht the new object model stuff.
pmichaud well, let me ask that more directly -- why can't we have a parrot-nqp in the parrot repo?
i.e., what are the blockers?
(I grant there are some... I'm just wanting a feel for what they are) 19:45
jnthn It's mostly lack of backward compatibility.
pmichaud that doesn't make any sense to me 19:46
i.e., backward compatibility shouldn't be an issue
jnthn Maybe I mis-understood the question.
pmichaud okay, let me rephrase it a different way
jnthn We certainly *can* put the new NQP stuff I've been doing into the Parrot repo. Provided we handle its dynop and dynpmc library.
pmichaud okay (more) 19:47
at a nqp-source level, nqp code should pretty much work as before, yes?
jnthn We probably can't replace the current version of NQP in the Parrot repo with what I've got in nqp-rx/nom
19:47 kaare__ joined
jnthn Yes, pure NQP source isn't the problem. 19:47
pmichaud I'm asking what is the blocker there. :-)
19:47 kaare_ left
jnthn Ah, OK. I can list a few. :) 19:48
6model doesn't support inheriting from PMCs at the moment, nor from Parrot classes. I may be able to partially pull it off, but I'm not sure it's a good use of time when Parrot folks are already considering switching to 6model or something like it for Parrot itself anyway.
19:49 cogno left
jnthn Note that having attributes storing PMCs or stuff from P6metaclass or Parrot objects is no problem at all. 19:49
It's when inheritance is needed that we hit issues.
A harder one is that multi-dispatch currently only knows about 6model objects.
I'm not sure that'll be too easy to handle. 19:50
pmichaud I don't think that there are many instances of nqp programs (well, except for parrot-built utilities) that really need inheritance from pmc classes
jnthn Yes, the Parrot built utilities are my big worry here.
I think for people using NQP to build compilers, this should be a smooth transition.
For folks using it as a nicer way to interact with Parrot than writing PIR, I think it will be harder. 19:51
pmichaud parrot-built utilities using nqp are likely to get a significant change anyway, since bacek++ is working on a nqp-based version of PIR and PAST/POST
19:51 molaf joined
pmichaud there are migration issues with that also. 19:51
jnthn Yes
pmichaud anyway, at this moment I tend to agree that the new nqp(s) are separate products from the existing nqp-rx 19:52
and so we may handle it much like pge -> nqp-rx; i.e., leave the existing nqp alone for backwards compatibility, create a new nqp-ish environment for people to migrate to
migration should be far easier this time since it's mostly at a hll (nqp) level, I think.
jnthn Yes, people won't have to go re-doing their grammars and stuff like that. 19:53
Well, I guess maybe they didn't *have* to last time...
pmichaud most did, because of changes to things like protoregexes and the base grammar classes
but that shouldn't be the difference this time 19:54
jnthn Right.
19:54 kaare__ left
pmichaud this time the changes are likely to be in PAST API stuff, I think. 19:54
jnthn Yes, and also at the interface between NQP and the VM.
19:54 kaare__ joined
pmichaud which comes to my next question -- what issues do we need to keep in mind to keep CLR capability? 19:54
19:55 kaare__ left
pmichaud or did you want to focus on parrot for the first step? 19:55
jnthn nqpclr is looking quite good overall in terms of what it's capable of.
I think we need to try and reify/declare a bit more when VM specific stuff is going on.
pmichaud is it very divergent from nqp-nom? what's the current relationship between the two?
jnthn There's a lot in common. 19:56
If we s/pir::/nqp::/ in the Parrot one, it gets even closer.
pmichaud okay
jnthn The way you write meta-objects on both is identical. 19:57
19:57 Vlavv left
jnthn The 6model implementation on both is pretty much API compatible. 19:57
pmichaud is it unreasonable to shoot for (not immediate step, but medium-term) having a single nqp implementation that can self-host on both parrot and clr?
jnthn There's some case where one leads the other in a given feature.
Medium-term, that's what I want pretty much. 19:58
pmichaud same here.
jnthn And what I've been keeping in mind.
pmichaud the -rx part of nqp-nom is still heavily dependent on PIR/Parrot right now?
jnthn Yeah
pmichaud how about past/post?
jnthn In two ways
tadzik Unicode property 'OtherAlphabetic' not found -- from the failing test 19:59
jnthn 1) It doesn't use 6model yet. That I can likely get fixed up.
2) Large swathes of it are in PIR. That's much more challenging.
PAST/POST - we don't actually need to switch those right now.
pmichaud they don't need new base classes? or you did that already in -nom?
TimToady phone? 20:00
pmichaud phone!
jnthn We don't need them to at the moment.
The thing is that our only interaction with them is to instantiate them and call methods.
pmichaud ah, so they can remain traditional Parrot objects w/o difficulty?
jnthn -nom is just fine with doing that stuff with objects from other object implementations.
pmichaud Pretty.
jnthn Yes, that I have managed to make work pretty effortlessly.
pmichaud Shiny.
20:01 coldhead joined
jnthn What is different is that 6model is...erm...annoying...to use directly from PIR. 20:01
pmichaud that's okay, I think.
jnthn Or at least
20:01 cogno joined
jnthn It won't be able to take advantage of the optimizations in a sane way when they land. 20:01
pmichaud (phone omw)
I'm not too worried about that. I expect/hope we'll be eliminating huge parts of PIR anyway. 20:02
jnthn What I'm looking at is moving Cursor stuff into a class (in NQP) but leaving various methods having PIR bodies.
pmichaud oh, I'm thinking Cursor could become heavily NQP
it was somewhat designed that way at the outset; I just never went back and nqp-ized it.
jnthn diakopter++ has already done a bunch of stuff on that in the 6model repo for nqpclr 20:03
pmichaud (and I was also dealing with efficiency concerns)
20:03 MayDaniel left
jnthn Yes, well, that's what I think we've hit in nqpclr too. 20:03
[Coke] does felliott still need privs?
pmichaud what sort of overall timeframe are you wanting?
[Coke]: I added him
diakopter blinks into attention
pmichaud (so no)
diakopter finishes backlogging 20:04
jnthn pmichaud: I think nqp-rx/nom will be at the point where I'm ready to start re-working Rakudo to use it and 6model in about 2 weeks.
pmichaud: I'm fine with working against a Parrot branch initially. Of course, will be doing the work in a git branch.
[Coke] pmichaud: danke. 20:05

Layla_91 Knock, Knock! :D 20:05
jnthn I can find ways to work with a separate, out-of-Parrot, nqp-rx/nom for a while if it's blocking me.
Layla_91: Привет!
pmichaud so, you'd like to see a nqp-nom in the parrot repo in about 2 weeks (more)
Layla_91 jnthn: You kow russian! yahooooo! :D
pmichaud or, we have a rakudo branch that loads+builds nqp as part of its configure/build process (like we did in the early stages of rakudo-ng) 20:06
jnthn Layla_91: A little. :) I'm really bad. :(
pmichaud: I'm fine with either way.
Layla_91 jnthn: I will teach you all the basics.. come to Russia soon and all your beer will be on me :D
pmichaud I prefer to have nqp-nom in the parrot repo somehow; far easier to manage
[Coke] oooh, free language lessons AND beer? awesome. 20:07
jnthn pmichaud: I think so too. My concern actually isn't for me immediately.
Layla_91: Wow! :D
pmichaud: It's more that at some point I'll want @other to join the hacking and or test there stuff on it. 20:08
pmichaud: And low barrier to entry is helpful for that.
pmichaud I'd like also like to see nqp-nom in parrot so parrot hackers can start looking at it and seeing its effects
Layla_91 [Coke]: You can come too :)
jnthn pmichaud: Of course, me not having to build temporary stuff also helps. ;)
pmichaud anyway, two weeks seems very doable

pmichaud: Er...
dukeleto YAPC::EU looks like it is going to be fun. I am seriously thinking about going.
Layla_91 [Coke]: It is easy.. take a plane and come XD
pmichaud jnthn: I think the next step is for me to build nqp-nom and see what I think :-) 20:10
jnthn pmichaud: Maybe you should know that 6model on JVM managed to start up, init 6model, initialize its (rather trimmed down) setting...and run hello world.
It passes a few tests too.
mberends++ for porting that lot :)
Anyway, it's a very reassuring that the model works so far on 3 different VMs.
pmichaud jnthn: okay, in the next 3 or 4 days I'll get nqp-nom installed and running on my box and add my reactions to that (more) 20:11
jnthn That doesn't demand your attention, anyways. It's just nice that it's happening.
dukeleto jnthn: it is very exciting to watch 6model evolve
pmichaud I'll also see about getting the clr version running, just to see it
jnthn pmichaud: OK. :)
pmichaud: Oh, I dunno if I made it clear...
pmichaud: nqp-rx's multi handling does all the proto stuff properly now
pmichaud: So it enters the proto and the * or {*} enters the dispatcher. 20:12
Also it can handle :U vs :D
So it's more than just "multi dispatch with 6model types", it's "multi dispatch that follows the latest spec", though it's missing all the stuff like constraints and sub-sigs and stuff (which I think will never go into nqp-rx). 20:13
Note that nqpclr supports all of this too, already.
pmichaud: Finally, pop github.com/jnthn/6model/blob/maste...erview.pod on your reading list. I writed docs!!1!! :) 20:14
pmichaud (on phone) 20:15
yes I understood that multi handling did proto stuff now 20:16
cogno I discover that Riga has a lot of art nouveau. I want to go if health and finance are good
pmichaud anyway, once I see the codebase I think I'll have a really good idea of what we need to focus on next 20:17
it does sound very similar to the rakudo-ng transition
jnthn OK. Warning, rough edges. ;)
pmichaud np, we had rough edges before :)
anyway, my goal will be to have a draft roadmap for migration by Sunday 20:18
jnthn If you can, that'd be outstanding, and very helpful.
pmichaud I'll also look at bacek's work and figure out where it should fall into things
I'm pretty sure I can do that by Sunday

masak flussence: you could really use a fourth spatial dimension to get a left-handed ergonomic mouse.
21:11 bacek_ left
masak I had this idea for a short story today, about objects that stuck together through an (invisible) fourth spatial dimension. you rotated one, the other one would go as a moon around it. or you could put one in the attic and swing freely from the other. 21:13
flussence
.oO( and then something 4D nudges them slightly out of place, and you get horribly dismembered... )
 21:14
masak well, the thing is that the extra dimension would be entirely inaccesible, and otherwise totally undetectable. no 4D monsters or anything. 21:15
I bet lue would appreciate this idea.

jnthn Anyway, www.fileformat.info/info/unicode/ch.../index.htm agrees that it's not a valid unicode char. 22:06
Seems that "for UTF-8 encoding" is kinda misleading.
If it's not a valid unicode char, I'd not expect it to work on any encoding.
flussence 0xd800..0xdfff are utf-16 surrogate chars, so it makes no sense to have them in utf-8.
jnthn Oh...I see. 22:07
oh, you're right...
