Matt-W morning azawawi
eternaleye Hi azawawi, Matt-W 06:09
moritz_ good morning
Matt-W wants to know how to move an operator into the setting
eternaleye oh hai, moritz_
Matt-W: Just define it in the setting, remove it from the PIR, and spectest! 06:10
Matt-W eternaleye: it causes a null pmc access :(
moritz_ ... in find_method?
eternaleye Well, that's _never_ right
moritz_ which operator?
Matt-W moritz_: yes. I was trying to do infix:<leg>
eternaleye I was just thinking, we're going to need to be careful defining operators in terms of other operators, because we might get an infinite recursion going. 06:11
moritz_ Matt-W: you also have to remove it from build/gen_junction_pir.pl
Matt-W ah
Matt-W tries that 06:14
06:14 synth joined
Matt-W ah that's better :) 06:14

eternaleye In any case, the first one appears wrong - it looks like it's returning from infix:<...> 06:17
Do we need to do a wrapping sub around $generator, so that it DWIMs
When I define the generator as a sub, and then use &nextprime in infix:<...>, it works 06:18

It should give a 5, a 7, etc

p6eval rakudo 5351a3:
eternaleye Nope, that is what's happening 06:26
Also, does that look like a NL symbol to everyone else? Since it looks like lower-a, circumflex acce,t, space, Euro sign here
moritz_ it looks broken here too 06:27

eternaleye _weird_
moritz_ hm, that looks fine
eternaleye Bug? 06:28
Running in local rakudo
moritz_ it loooks OK on the IRC logs, though
Matt-W woohoo
my operator passed its part of the spectest
what's the preferred way to submit a patch?
moritz_ eternaleye: ah, I know why... the last NL character got trunkated, so our IRC client's autodetection thought "that's not valid UTF-8" and went beserk. 06:29
Matt-W: [email@hidden.address]
Matt-W moritz_: yes but how to make the patch
eternaleye Ah
Matt-W moritz_: unfamiliar with git for this
eternaleye Matt-W: git format-patch --stdout 'HEAD^' 06:30
and nopaste/rakudobug/email/etc it
Or remove the --stdout and it'll make a file
I like the --stdout, so I can pipe it to wgetpaste 06:31
moritz_ Matt-W: first commit it (git commit -a)
Matt-W: then git-format-patch HEAD^
Matt-W: and attach the generated file
Matt-W sends 06:34
and just in time to go to work too
I'll be back later

I do wish people would discuss these things a bit before attacking the spec... :/ 10:54

masak to me, IO::Endable is perilously close to abstraction astronautism.
just give me the IO.end and be done with it. 10:55
no need for a whole interface for it.
jnthn (e.g. it was meant to be defined in IO::Endable, but somehow forgot)

ruoso heh... jnthn++
but seriously... that's the plan... I mean
once we have multi and module loading working
pugs_svn r27350 | pmurias++ | [re-smop] correct indentation
r27351 | pmurias++ | [re-mildew] fix if bug
ruoso we can start working on Perl 6 features
pmurias and when's the bootstrap point? 12:54
ruoso well, there's the type system bootstrap
that should happen soon after we have module loading
but then there's a long way before we implement a grammar engine in SMOP
12:55 Chillance joined
ruoso and then this grammar engine will have to be able to run STD 12:55
12:55 Molaf left
ruoso and we must be able to parse STD using that grammar engine 12:56
and, finally, have this grammar engine being used to compile STD to SMOP
and that's the real bootstrap
pmurias a partial bootstrap would be to have mildew in Perl 6 and using the STD compiled down to perl5 12:57

pmichaud From a performance perspective, it might be worthwhile to also write a infix:<leg>(Str $a, Str $b) { ... } variant. 13:46
Matt-W Mmm good point
would save two calls to prefix:<~>(Str)
pmichaud but we can/should probably wait until we have a way to measure the performance :-)
Matt-W (in the str case)
yes :)
or perhaps until there aren't various other crippling performance issues :) 13:47

masak I keep forgetting that the '?' quantifier creates Arrays in the Match tree... 13:52
jnthn masak: Took me a while to remember that one too. :-)
pmichaud yes, I've had that trouble also. Especially since in an earlier draft of the spec the ? quantifier *didn't* create arrays. :-)
masak oh, so it was added? 13:54
would be interesting to hear the rationale for that.
it doesn't feel immediately obvious that it should.
pmichaud "all quantifiers produce arrays"
masak ok, so consistency.
pmichaud right.
also so that ? remains the same as ** 0..1
masak oh, that's a nice reason. 13:55
pmichaud previously ? was the exception to the rule... and I think the desire was to eliminate exceptions.
Matt-W it makes a nice consistency
? not matching just gives you an empty array
which suits me
although I thought the whole capture thing was broken last night... turned out I'd made a stupid one-character mistake 13:56
13:56 frew left
Matt-W no matter how cool Perl 6 is, it's not going to protect us from those 13:56
masak no, but clueful error messages go a long way. 13:57
13:59 cls_bsd joined
Matt-W well my mistake was syntactically valid... 13:59
I was just ending up with an undefined value
which should not have been undefined
I thought it wasn't capturing properly 14:00
but of course it was
$colleague over there *points* is eating an ice cream!
14:01 frew joined 14:03 frew_ left
masak Matt-W: ice cream is overrated. it's just frozen sugar. 14:04
jnthn Frozen flavorings too!
14:10 mkindahl left
Matt-W and frozen cream! 14:15

masak Rakudo still returns 0 when it finds a syntax error. :/ 14:29
that way, running 'make test' proceeds to the tests even when the build fails. 14:31
14:33 mkindahl joined
masak ooh, I found another one! 14:33
rakudo: regex foo { foo }; "foofoofoo" ~~ /<foo>+/; bar($<foo>); sub bar(@foos) {}
p6eval rakudo 5351a3: OUTPUT«Parameter type check failed; expected Positional, but got List for @foos in call to bar␤in sub bar (/tmp/FtrwyZv3La:2)␤called from Main (/tmp/FtrwyZv3La:2)␤»
masak jnthn: how does that happen?
masak submits rakudobug 14:34
jnthn Probably to do with the way Match objects are made perhaps 14:37
14:37 rfordinal left
pmichaud I'm guessing that ResizablePMCArray doesn't ~~ Positional 14:37
jnthn rakudo: regex foo { foo }; "foofoofoo" ~~ /<foo>+/; say $<foo>.PARROT
p6eval rakudo 5351a3: OUTPUT«ResizablePMCArray␤»
jnthn Right.
pmichaud That's likely to be an issue.
moritz_ rakudo: my @a = 3, 4; say @a.PARROT 14:38
masak it is an issue.
p6eval rakudo 5351a3: OUTPUT«Perl6Array␤»
jnthn Not sure quite what we can do about it off hand.
moritz_ can't you just invoke some magic that type-maps RPA to Perl6Array?
pmichaud moritz_: not easily.
masak more workaroundly, what's the easiest way to convert the former to the latter?
buubot masak: Sorry, no more output
pmichaud but in the larger sense, we need for non-Rakudo arrays to still be treated as Positional
masak buubot: shush! 14:39
buubot Couldn't match input.
moritz_ is about to kick buubot
pmichaud i.e., if we're ever to get language interop to work.
jnthn Probably need to as a fall-back check if it provides array from a Parrot POV too.
pmichaud I'd be fine with adjusting Positional.ACCEPTS to check "does array"
jnthn Me too, if that was actually easy to do. 14:40
pmichaud it's not?
masak ah. .list worked.
jnthn Not until we have a decent way to provide a non-punning ACCEPTS on a role or something. 14:41
I (and afaict the spec) are a bit hazy on that area. 14:42
pmichaud how does Positional.ACCEPTS work now?
jnthn It's just Perl6Role::ACCEPTS 14:43
Positional is an instance of Perl6Role
pmichaud and we can't override ACCEPTS ?
jnthn Not without mixing another ACCEPTS into Positional, but not sure what else that would do as a side-effect. 14:44
pmichaud okay. 14:45
jnthn Though this is all tied into "how we do define non-punned methods on a role separate from punned ones?"
pmichaud I don't understand "non-punned" versus "punned" in this context.
jnthn And I've not seen an answer to that yet.
role Foo { }; Foo.new # puns
Foo.ACCEPTS($thingy) # can't pun 14:46
At the moment, the dispatcher just has a "magic list"
But that's almost certainly not the Right Answer.
I just don't know what the right answer is.
pmichaud Oh. Do the :U, :D, etc modifiers have anything to do with that?
or is that totally separate?
jnthn Possibly.
Matt-W hmm, a magic list sounds bad 14:47
jnthn We could maybe make them mean that in the role invocant case.
14:47 kidd_ joined
jnthn Would need to think some more on how sane that is. 14:47
Matt-W In my head, it's all simple 14:48
Until I remember that PGE is a Parrot thing, and is going to speak Parrot types that don't know about things like ACCEPTS
14:49 m-i-l-a-n left
pmichaud well, I may be able to get PGE to do some sort of type mapping, but specifying that mapping is a bit of a pain atm. 14:49
masak interoperability theory is so much easier than interoperability practice.
Matt-W interoperability is easy the moment you try something more complicated than making something interoperate with itself
*until the
14:50 m-i-l-a-n joined 14:51 payload left
Matt-W Does this also have impact on things like getting objects back from, say, a Ruby module? 14:52
Or is that a different problem
pmichaud same problem.
Matt-W well that's something at least
only have to solve it once...
14:53 finanalyst left
Matt-W seems easy to say oh let's have some sort of mapping so that we know that RubyList and ResizablePMCArray do Positional, but I guess that could get big and fragile 14:53
pmichaud jnthn: why is it the method that does the punning? 14:54
jnthn pmichaud: I don't get the question.
pmichaud: ah
pmichaud I would think it's vivification that forces punning.
jnthn pmichaud: It's the dispatcher that realizes you're calling a method on a role and decides "ah, we need to pun"
vivification? 14:55
