thei0s in synopsis 5 there is an example for something else, but it says: $_ = "foodbard" 14:29

/ ( foo | bar ) d <$0> / # fails; doesn't match /foo/ as subrule

moritz_ it would help even if simple, one-dimensional eager slices where implemented
ruoso: I think that the current concept of slice context was invented after pugs developmented had stalled 15:47
ruoso hmm... ok
anyway... there's one specific line in the specs that freaks me out
the one that says that @a and @@a are actually the same variable 15:48
because that means that 15:49
my @a <== grep { ... }, ...
say @a[0]; say @@a[0];
will at first say the first item returned (regardless of empty captures in each grep iteration) 15:50
and at second say the capture of the first iteration
is the second '@' in '@@a[0]' a twigil? or is that parsed as @(@a)[0] ? 15:51
dr_df0 jnthn: I figured it out, on my SVN checked out version, but I wanted to check how pugs is handling this syntax 15:52
moritz_ ruoso: it's not a twigil
ruoso: I'm pretty sure that @@ is syntactically a sigil
ruoso gah 15:53
that's even weirder
moritz_ why?
token sigil:sym<@@> { <sym> } 15:54
ruoso is that part of STD?
moritz_ aye
there's no need why a sigil needs to be just one char long 15:55
[particle] yes, @@ is a sigil, just like :: used to be
ruoso so @@a and @a are different variables, 15:59
since the variable name includes the sigil
moritz_ I think that's an exception here
@@a is a different view of variable @a 16:00
16:00 stephens joined
ruoso that's the part that freaks me out 16:00
what does that mean, for every @a, the lexical scope also holds a reference to @@a?
s/to @@a/as @@a/ 16:01
moritz_ no, it's really the same variable
but @@a on the lhs implies slice context
while @a on the lhs implies list context
ruoso so, slice context is only possible on lists that are stored in variables with the @ sigil?
moritz_ you can still say my $a = @@( EXPR ) 16:02
as far as I understand, @@a = ... is just shorthand for @a = @@( ... )
pmichaud btw, @a[0..2] is the case that starts to make me think that perhaps Range ~~ List 16:05
I thought about that one last night.
ruoso moritz_, @a = @@(...) implies list context over the rvalue slice, which should flatten the list 16:06
pmichaud, I think the confusion is about the "Positional" role
pmichaud ruoso: there's confusion about that also.
ruoso I think what I've been calling List is probably "Positional"
but I don't see much of a point in having both List and Positional
pmichaud I think of them as separate issues 16:07
ruoso maybe List is the only one that supports Slice context... 16:08
while positional doesn't
but...
(1..9)[3..4] should work
pmichaud otoh, since subscripts are always evaluated in list context, it probably doesn't matter if Range ~~ List 16:09
ruoso at least a Range can be coerced to a Lazy Lis
Lazy List
pmichaud correct.
ruoso so maybe .Iterator() is not a method of List

..rakudo 33456: OUTPUT[1␤]
..pugs: OUTPUT[1234␤]
ruoso but a method of Iterable 16:10
where both List and Range are Iterable
dr_df0 what should @a[] return?
pmichaud all of @a
dr_df0 so it's a bug in rakudo
pmichaud rakudo currently thinks of @a[] as being @a[0], I suspect. 16:11
slices are still unimpl in rakudo
(although I'm looking at that now)
rakudo: my @a = <a b c d>; say @a[];
p6eval rakudo 33456: OUTPUT[a␤]
ruoso and maybe certain operators expect an Iterable
like feed 16:12
dr_df0 you're right that's also special case of slice
pmichaud I think I may be able to get rvalue slices to work fairly quickly. lvalue slices might take a bit more work (either that or we just cheat and vivify everything in the slice even if it's not lvalue)
ruoso anyway... got to go... 16:13

ah, <=> is numeric semantics, right? 16:57

moritz_ not only, it's generalized 17:00
perl 5 <=> is called 'leg' in Perl 6
(less, equal, greater)
no, I confused that with cmp 17:01
forget what I said
riffraff I found leg, yeah it seems to be string comparison and cmp is the general one
moritz_ right 17:02
and <=> is still numeric-only
sorry for the confusion
riffraff no worries :)

that's when you run into that, because it calls Parrot with some "die on double free accidents" flag. 17:26

ruoso but it seems that named arguments must be explicitly in the "first level" in the capture 18:12

moritz_ jnthn: since an enum item is also a type, and .WHAT returns the short name of a type, i'd say you have an answer ;-) 20:54
jnthn masak: It may turn out that's what A::baz.WHAT is meant to do.
masak the sooner it turns out that way, the better :)
jnthn moritz_: Aye, it could be argued that the individual values are just instances of the role A and it should say A, or it could be argued that the values are actually Ints by default so it should say Int...

pmichaud I suspect infix:<xx> is miswritten.
jnthn pmichaud: Yup, I suspect the same.
pmichaud I bet it just puts the same PMC in the list multiple times.
jnthn It's just sticking the...yes.
:-)
pmichaud oh, actually....
jnthn Well, should be easy rakudobug to fix.
pmichaud I think infix:<xx> is okay in that sense, and assignment is broken. 20:58
moritz_ speaking of easy fixes, would somebody please review #60976?
pmichaud I already know that list->array conversion isn't right -- I was working on that.
jnthn I think the problem is that array elements are containers and need to be initialized as such.
pmichaud I looked at the patch for 60976, and while it "feels wrong" I couldn't come up with a better answer for now. 20:59
it's okay with me if someone applies it.
jnthn (Which does fit with list->array conversion wanting a fixup)
20:59 thepler joined
moritz_ pmichaud: ok, will do then 20:59
pmichaud jnthn: it's part of my whole "I want to redo assignment again" brain branch
it's not a major redo, just some of the details. 21:00
jnthn At least it only takes an afternoon each time you decide that. ;-)
pmichaud the basics remain the same, just some of the individual operations change
jnthn OK
pmichaud jnthn: which would you take as a better use of my time today/tomorrow: parameter refactor, or assignment & slices ? 21:01
jnthn BTW, do you have postcircumfix:[ ] and postcircumfix:{ } on the "things you'd rather do yourself" list, or can I take a crack at those?
pmichaud the postcircumfixes are definitely part of assignment and slices
jnthn OK. Are you going to do list assignment within that? 21:02
pmichaud at least a first cut, yes.
jnthn OK, I'd say go for that.
We need to do both of course.
pmichaud yes, I'm thinking the same.
jnthn OK. 21:03
Is there anything you want me to look at, aside from the Perl6MultiSub stuff that is currently broken? 21:04
pmichaud that would be my priority at the moment.
pugs_svn r24145 | moritz++ | [t/spec] unfudge passing test for rakuo (subtypes.t)
jnthn OK.
pmichaud out of curiosity, is there a way that we can do mmd on ObjectRef ? 21:06
21:06 riffraff left
jnthn Trouble is that it appears fairly transparent to the dispatch. 21:06
pmichaud yes, I know.
if not, it's okay -- I was just curious. 21:07
jnthn It responds do isa.
As in, if you do isa it hijacks it and knows it's an ObjectRef.
pmichaud right, I use that already.
I was just wondering if it could be that way in the :multi() as well. But I was guessing it'd be problematic, for the reason you cite.
I'm thinking I'll likely hijack the assign opcode. 21:08
jnthn Perl6MultiSub would check that, I think, while I don't know that Parrot's MMD does that. You maybe, if you can create a ProtoObject for ObjectRef, can make it work.
But it'd have to be using Perl6MultiSub and have a signature. :-)
pmichaud oh, I'm thinking replacing our use of 'copy' with 'assign'
and fix 'assign' to dtrt 21:09
jnthn As in, change the actual Parrot op?
pmichaud for Perl 6 types, yes.
since I don't expect to ever have a non-Perl 6 type as a container.
jnthn If we're doing something Perl 6 specific, should we not be creating our own assign op?
(dynop)
pmichaud yes, but previously Rakudo would sometimes get Integer or String or Float or ResizablePMCArray as containers 21:10
rakudo_svn r33463 | moritz++ | [rakudo] make 'where /regex/' subset types work. riffraff++. Closes RT #60976
r33463 | moritz++ | Patch courtesy by Gabriele Renzi <rff.rff at gmail.com>
pmichaud (long ago)
then we moved to Perl6Scalar, but we went with infix:= as a method because there were still cases where array elements were non-rakudo types
jnthn isn't following
Can you give me a little more specifics?
pmichaud before we had Perl6Scalar, variables could be bound to Parrot types 21:11
thus my $a = 3 * 4; would end up with $a as an Integer PMC and not an Int
jnthn Ah, yes.
pugs_svn r24146 | moritz++ | [t/spec] tests for RT #61026: infix:<xx> should return independant copies of
r24146 | moritz++ | value types
pmichaud obviously I can't change the assign vtable for Integer
jnthn No. 21:12
pmichaud then we went to Perl6Scalar, where $a held a reference to its value
that worked for my $a = 3 * 4; but didn't help with @a[4] = 3 * 4;
because @a[4] wasn't itself a Perl6Scalar PMC
i.e., it would still end up being an Integer PMC
so, the alternative was to have arrays be arrays of Perl6Scalar PMCs (bad), or come up with a way of marking PMCs as containers 21:13
my position at the moment is that all of our containers will be a rakudo-specific type, or at least act like one (ignoring HLL interop and binding for the moment) 21:14
so, while we can't override assign vtable on Integer PMC, we definitely *can* override it for Int.
jnthn Yes, true.
pmichaud so we just make sure that everything that goes into a container is something that's a subclass of Object 21:15
or an ObjectRef
or some other type that we "control"
and if not then it's coerced to one.
jnthn OK, e.g. by wrapping it up in an ObjectRef.
pmichaud This is what I'm doing now to automatically coerce Parrot String PMC into Str objects.
anyway, it should all "just work". Even better, we can be a lot more efficient than 'copy' 21:16
.
pugs_svn r24147 | moritz++ | [t/spec] another two tests for RT #61026
jnthn Yes.
pmichaud by not creating unneeded clones.
jnthn (Also note that we can tell if our caller is from a different HLL very cheaply, once .HLL is in place.)
(So we only need to do the coercion path in a signature to handle interop if it's needed.) 21:17
Erm, when bidning to a signature.
But let's get it right for calls within Perl 6 first.
pmichaud when binding to a result that isn't a rakudo object.
exactly
I'll handle the p6 case now, an interop a bit later. 21:18
*and
jnthn Well, if we handle it when binding a signature...
Since HLL interop is pretty much at the sub level.
pmichaud yes, it could happen then. Depends on how well other-HLL subs play with our calling conventions.
jnthn But yes, p6 case now.
pmichaud okay, I'll work on assign+list assign+slicing today
(and a few pct updates for subid) 21:19
jnthn Great. :-)
I've been handling $other_stuff today.
pmichaud I may want to add roles to P6object, too :-)
21:19 rindolf left
pmichaud at least make it easier to attach roles to newly created classes. 21:20
jnthn Yay roles! :-)
pmichaud oooh
I wonder if 'parent'=> ... should really be 'does'=> ... in P6object
jnthn It'd be nice if future additions to P6Object could match the HOW API in www.perlfoundation.org/perl6/index....mop_oo_api 21:21
(The Declaration API section is relevant here) 21:22
parent can handle it too, since that's not in the API.
(That is, if the methods on P6Object are a superset of those in the HOW API, we make life easy for ourselves... :-)) 21:23
pmichaud well, those methods are really on P6metaclass
jnthn Yes.
pmichaud it's been my intent to do something like that with P6metaclass, although I hadn't been following this section precisely
jnthn OK. I think what's under HOW API and Declaration API is likely to become spec. 21:24
pmichaud but we now have an 'add_method' method under P6metaclass, for example.
jnthn (As in, the stuff you need to implement to make your own metaclass)
Yes. And I think it matches this API already. :-)
pmichaud if not it's pretty close. 21:25
jnthn Curiously, the API appears to be missing an add_parent 21:26
pmichaud indeed, I was just noticing that.
maybe bless...?
the *@protoobjects argument...?
jnthn No, those are the things with the WHENCE closures attached for auto-viv. 21:27
pmichaud compose_role, then? 21:28
jnthn Composition is a fundementally different operation to inheritance.
pmichaud true.
jnthn I really don't think the two should be conflated.
Especially as every class implies the existence of a role of the same name...
pmichaud anyway, it's a good target to work with for now. 21:29
jnthn Yes.

lambdabot Consider it noted.
masak report from the front: game programming in Perl 6 is fun!
pmichaud anyway, the advantage of assign vtable is that we get our "automatic dispatch based on assignment type" 21:31
jnthn Yes.
moritz_ masak: do you find different bugs than during wiki programming? ;-)
pmichaud without having to do a lot of 'isa' tests.
ruoso jnthn, it probably is
lambdabot ruoso: You have 1 new message. '/msg lambdabot @messages' to read it.
jnthn And probably rather cheaply too.

jnthn ruoso: Ah, you're on the channel! :-)
ruoso jnthn, :) 21:32
jnthn ruoso: In method dispatch($how: $object, $responder, $identifier, $capture --> Any) {...}
What is $responder?
pmichaud I'd really like to see us get masak's use.perl postings into the planet perlsix feed.
who can make that happen? 21:33
ruoso jnthn, well... it's the responder interface for that object... but I presume we can drop that 21:34
moritz_ pmichaud: mailto:webmaster@perl.org
pmichaud moritz_: thanks.
moritz_ it's a perl.org site after all ;-)
pmichaud composes mail.
jnthn ruoso: OK, I'm not sure what the Rakudo equivalent would be there. 21:35
ruoso and it doesn't really matters to such high-level
masak if a set of game rules are copyrighted, what restrictions apply to an implementation of a game implementing those rules?
ruoso jnthn, but, at least in smop, it would return the representation 21:36
most of the time, p6opaque
moritz_ masak: I don't think there's an universal answer for every country
jnthn ruoso: OK.
If we can drop it, that clears up one of my questions about getting Rakudo to match this API. :-) 21:37
masak moritz_: I see. my main concern right now is whether I dare commit the source to this game I'm working on to the Pugs repo.
jnthn afk for a bit
ruoso jnthn, yeah... we can drop it... if one needs the responder for the object it still can ask for that directly on the invocant 21:38
jnthn ruoso: OK, great. :-)
ruoso jnthn, but note that $object in the dispatch is not the invocant
jnthn, I should probably rename that in the signature to $proto 21:39
jnthn Oh?
ruoso wait a sec... let me check something and I'll rephrase that
jnthn It's the proto-object instead?
21:40 bacek left
pmichaud it's the "class" that you're manipulating 21:40
the invocant is just the metaobject
(so yes, it's the protoobject.) 21:41

21:41 Lorn left
ruoso yeah... I think so... 21:41
jnthn ruoso: But isn't this the thing to dispatch a call? 21:42
pmichaud oh, sorry, I was thinking of something else.
yes, in dispatch I would expect it to be $object
jnthn Me too.
It's the thing on the LHS of the . operator.
Which may be a proto. 21:43
But may not be too.
pmichaud right, but doesn't have to be.
ruoso right... I was confused by the fact that p6opaque is currently not implementing what is on the wiki
masak moritz_: I just emailed you the source code so far. I need to show someone, but I don't dare upload it. :) 21:44
pmichaud afk for a bit -- need a short break 21:45
ruoso jnthn, $object.^dispatch("methodname", \($capture)) is a syntax sugar for $object.HOW.dispatch($object, "methodname", \($capture))
so yes, $object is the same as the invocant
jnthn Yes. Good. :-)
You had me wondering there... :_)
OK, I'm afk too - need to do my Slovak homework before the lesson tomorrow
ruoso which means that you can have a different invocant in the capture you send to dispatch 21:46
jnthn, beware of $object.^dispatch("methodname",\($otherobject: $as, $invocant))

jnthn Yes.
We should.
See, it works. ;-) 23:06
thei0s ups :D
masak jnthn: you are evil :)
jnthn thei0s: I'm being cruel, because say "foo" is valid PIR, as well as Perl 6. :-)
And what is between the {{ and }} is interpreted as PIR.
pmichaud: If I were to do a Rakudo day on Friday, how would that be? 23:07
pmichaud jnthn: that would be _excellent_
23:07 adc_penner2 joined
jnthn OK, good. 23:07
masak +1
jnthn Tomorrow would be less good for me.
pmichaud same here
jnthn Great. :-)
pmichaud while on my break I got asked to be the "emergency presenter" at tomorrow's unix meeting.
because their other presenter cancelled out 23:08
so I should come up with a presentation, I guess. :-)
jnthn Nice!
pmichaud (I'll just recycle an existing one.)
jnthn I've got no more talks this year.
pmichaud I thought I was done for the year.... but apparently not.
jnthn I'm now onto pondering what to talk about at next year's European Perl workshops.
pmichaud it does look as though I'm headed to Frozen Perl, though. :-)
jnthn Nice. 23:09
You still pondering Oslo?
pmichaud yes.
jnthn They're hosting a Perl 6 hackathon, dates are set.
If you didn't already know that.
pmichaud I didn't know that, that makes it more likely (depending on the dates)
jnthn Workshop April 16th to 17th 23:10
Hackathon April 18-19
pmichaud I think Paula wants to make a trip to Europe sometime in 2009 -- we're just trying to figure out when.
jnthn www.perlworkshop.no/npw2009/
lambdabot Title: Nordic Perl Workshop 2009
jnthn Spring is nice. ;-)
pmichaud I should submit a talk or two. 23:12
jnthn Aye. 23:13
pmichaud adds the feed to his reader. 23:14
jnthn So far I'm probably going to be at the Nordic, Ukrainian, Belgian and one more as-yet unannounced-that-it's-happening workshop. 23:15
pmichaud I'm thinking Oslo might be a good time for us to meet and plan next phases 23:16
jnthn Yes, I agree.
And the fact they're hosting a Perl 6 hackathon is a bonus.
pmichaud indeed.
jnthn Hey, by then we might have LTM, parametric roles and all kinds of exciting stuff. :-) 23:18
thei0s jnthn: hm, I can't find how (if possible?) is it to access from PIR code a previously captured match (eg $0)... any suggestion where to look or how it should be done?
pmichaud the current match object is 'match'
jnthn $P0 = match[0]
thei0s 10x both
pmichaud token foo { (xyz) {{ $P0 = match[0]; say $P0 }} }
(I _think_ the semicolons get converted into newlines.) 23:19
masak thei0s: it's possible to make Rakudo generate PIR code for you by passing the --target=PIR flag to ./perl6
pmichaud no, they don't.
masak it sounds like a good idea, though. 23:20
pmichaud the problem is if there are any semicolons in string constants.
or things where they shouldn't be treated as newlines.
masak aye.
a problem generally known as 'parsing' :) 23:21
pmichaud if only we had a tool that made it easier to do parsing... :)
jnthn Hey, we have something for that... ;-)
masak quit stealing my lines! :)

p6eval rakudo 33467: OUTPUT[1 2 3␤]
masak what is it that does the flattening in this case?
[particle]1 what's the sprintf signature?
moritz_ I guess it's sprintf($format, *@args) 23:29
masak aye
our Str multi method sprintf ( Str $format: *@args ) is export
moritz_ then the slurpy would do the flattening
masak so it's that splatty star there?
I see.
goodie.
moritz_ "slurpy" now, "splatty" is the old name
masak feels old 23:30

[particle]1 i'm older than perl. you? 23:31

pmichaud perl becomes "legal" this month :-)
masak only in the US
[particle]1 well, perl can drink then.
pmichaud I'll drink to that! :-)
[particle]1 "legal" happened almost three years ago

masak I've written some wild Perl 6 tonight. 23:43
indexing an array of closures, for example. poor man's switch statement :) 23:44

p6eval rakudo 33468: OUTPUT[Null PMC access in isa()␤current instr.: 'infix:=' pc 11153 (src/gen_builtins.pir:6873)␤]
masak yes! :)
what did I just do? :) 23:49
thei0s iii... my first working PIR workaround (unfortunately because of newlines not IRC-bot compatible) -- implements matching to already captured subrule $/[0]<ab>
token Test1 { (<ab>'a') .*? {{
$P0 = match[0]
$P0 = $P0["ab"]
.return($P0) }} }; token ab { 'ab' }; say ( "abaaab" ~~ Test1 ) ?? "ok" !! "not ok";
pmichaud .return does weird things in regex closures. 23:50
it almost certainly doesn't do what you expect.
masak thei0s: when submitting longer pieces of code (and preferable also shorter), consider using nopaste.
pmichaud (because it's based on an old spec)
[particle]1 pmichaud: thei0s pir is on topic for #parrot, not #perl6 23:51
ah, i see you're not there right now...
thei0s hm, true
[particle]1 oh, nm 23:52
it's fine, that's actually perl 6 with inline pir
[particle]1 is a bit behind, sorry

masak that was today's strange bug! 23:54
time to go to bed...
moritz_ bed is a good idea

23:55 masak left
[particle]1 pmichaud: is there a way to call 'make' from pir embedded in p6rules? would that work better than 'return'? 23:55
pmichaud [particle]: match.'result_object'($P0) 23:56
[particle]1 ah, right! excellent.
thei0s I have one more question for now: in synopsis 5 there is a test (capture.t, line ~69): ok(eval(' "bookkeeper" ~~ m/<single> ($/<single>)/ '), 'Named backref', :todo<feature>); 23:57
imho matching for $/<single> is problematic, because the parser can not know if you mean $/ followed by <single> or $/<single> 23:58
a rewrite of this to $<single> would solve this problem, but would not solve a situation where we have $/<single><sth> 23:59
23:59 dr_df0 left
[particle]1 wonders how STD.pm parses that... 23:59
$/.<single> also disambiguates
