Set by sorear on 4 February 2011.
soh_cah_toa yeah, parrot needs a good `git gc` 00:00
[Coke] it is teh awesome. (now that I'm coming at it from git-think instead of svn-think)
sorear benabik: I wonder if git gc would improve that.
[Coke] soh_cah_toa: can you do that on the server side?
benabik sorear: That's post-gc.
sorear ah.
soh_cah_toa [Coke]: i think so. i can't imagine why not
[Coke] ask dukeleto, I'm sure he'll hook you up.
flussence [Coke]: I've used it too, but it doesn't seem to play nice with our ridiculously outdated servers hosting the svn repos... it got corrupted after a few commits one time and I had to fix the metadata by hand. Not fun 00:01
diakopter [Coke]: trac.parrot.org/parrot/ticket/2196 00:04
00:09 Chillance left
[Coke] flussence: I'm using it against svn 1.4 at work. 00:10

flussence I don't remember what ours is offhand, but it predates fsfs 00:11
diakopter [Coke]: it might be a cygwin/Win7 local problem
[Coke]: did a rebaseall; trying again 00:14

jlaire I used to get errors like that with cygwin/Win7 00:20
it broke after some cygwin update failed, iirc 00:21
I just tried building rakudo with --gen-parrot on cygwin and got a weird error, pasting..

just look at perl6.org/compilers/features :)
snarkyboojum the list of features comparison certainly shows it's close
yeah that

13:45 f00li5h joined
masak im2ee_: arrays are made for putting things in them. if you're clearing the array, you're doing the *opposite* of what it was meant for. just saying that's not ideal -- without seeing the code I can not suggest a better way. :) 13:46
and the use case may indeed be entirely legitimate, too. it depends.
13:55 alvis left
masak im2ee_: generally, I've been settling on a style of coding where I don't "overwrite" values in variables. filling up an array is nice, but if I need to take away values, I always consider whether I don't actually need a new array instead. 13:57

it does different things for Int, Num, and Rat, for example. 14:32

jnthn moritz: re "Parents cannot be added to a class after it has been composed", I consider that the way standard Perl 6 classes work. If people want that they can write a custom meta-object that supports it. 17:29
jnthn ain't so into kitchen sinks that sink optimizability :) 17:31
moritz: The default-not-typechecked thing is certainly a bug. Will investigate that one. 17:32
17:32 donri joined
GlitchMr If I see "Unhandled Exception" it's bug in niecza, right? 17:33
It sometimes happen with invalid syntax and those exceptions aren't helpful...
pmurias jnthn: that seems inconsitent with being able to add methods at runtime
jnthn pmurias: It's not at all.
pmurias: They have very different consequences.
pmurias jnthn: what are the serious inconsequences of adding parents? 17:35
jnthn pmurias: They may want to bring in other attributes, which is a problem if you want to settle on a particular layout for objects.
pmurias: If you have a "we store attributes in a HoH" view of the world it's not a problem. But P6opaque doesn't work like that.
I guess we could say "it's OK provided the parents don't bring in more attributes". 17:36
I'm not sure it's worth the complexity though.
pmurias do we expose the way P6opaque is implemented somewhere 17:37
?
jnthn pmurias: "expose" in what sense? 17:38
Different representations all implement the representation API, but they can all make different trade-offs. That's kinda the point. 17:39
pmurias that settling on a particular layout is a part of the language model rather then an implementation feature
jnthn Well, I don't think the spec has to - or should - commit to a layout.
It should probably make it so the expectations on the default ClassHOW and its default representation allow for something fairly efficient though. 17:40
(Efficient in the common cases, that is.)
pmurias from an implementors world view i fully understand why you (and me) want to settle on a layout
jnthn Well, we can't box things in too much on layout.
pmurias but if an user is doing monkey patching he may want to add an attribute
we could put the extra one in a HoH ;) 17:41
jnthn Then the user will get the error, google it, and see the answer: "use Meta::Class::VeryCustomizableAlways;" :)
pmurias: I pondered doing that, but it's another pointer on every object. :( 17:42
Which adds up.
pmurias not nessesarly
we would use to object as a key of an extra attributes hash
slow but it's an optional feature for hardcore monkey patching 17:43
jnthn True, but that has GC implications.
Well, if people want hardcore monkey patching, I think that's something we can fairly say falls into the scope of a module.
What the default ClassHOW says is a set of defaults ideal for the common case, not something that sets the limits on what is possible. 17:44

GlitchMr There is shortcut for that!

TimToady note that ('a'..'z', 'A'..'Z', '0'..'9').roll for 1..10 has to rebuild the list every time through the loop
well, unless the optimizer notices that it can constant fold it 18:47
but none of the implementations are good at constant folding yet
it's funny, because constant folding is one of the most useful optimizations, but people seem to avoid doing it for some reason 18:49
GlitchMr It reminds me what I was doing to generate random strings in PHP 18:50
$return='';for ($i=0;$i<7;$i++){$return.=chr(rand(97,122));} 18:51
It would be even more complex if I would include uppercase letters and numbers...
And there is no useful .. operator. 18:52
masak TimToady: I'd definitely expect a constant list (Parcel, whatEVER) to be within the reach of an optimizer. 18:56

masak :) 22:44
it should output "before\nin macro AST<nnnnn>\nfoo\nafter\n".
tadzik what's "quasi"? 22:45
Tene masak: was it as straightforward as I thought it would be?
masak Tene: how should I know? :P
tadzik: it's a block of code that turns into an AST.
jnthn masak: I hope it says "in macro AST<nnnn>" before before, given it should happen at compile time...
masak jnthn: oh! yes. 22:46
my mistake.
tadzik I see
Tene masak: I thought we had discussed implementing that previously. Apparently not. :)

Make List.shift cheaper in the (common) case that we have an element. This in turn makes list assignment cheaper, wich does a gimme to ensure there is an element, followed by a shift.
masak tadzik: at present, you can pass in ASTs into a macro, and you can return ASTs, but there's no way to manipulate them on the way through. 22:52
Tene masak: Very nice work.
tadzik masak: so I can't quasi { $b }, right? 22:53
soh_cah_toa could somebody help clarify what the 'handles' keyword is for? the spec (as usual) is hard to understand there 22:55
jnthn soh_cah_toa: Delegation.
tadzik: I guess you meant quasi { {{{ $b }}} }
masak tadzik: it would be... what jnthn said.
jnthn Though that'd just be returning $b anyway.
tadzik ooh, what'd that be?
oh, that's the way you use it, I suppose? 22:56
masak and yes, just returning $b would be easier.
tadzik hrm
masak tadzik: yes, it's like string interpolation but with ASTs.
tadzik is there a spec up-to-date?
masak sure.
tadzik kay, I'll just read that
soh_cah_toa jnthn: uh, ok. could you elaborate? ;)
masak but if I were you, I'd read it with my gists.
tadzik :) I'll do that
masak tadzik: gist.github.com/1148915 gist.github.com/1149126 gist.github.com/1156662 22:57
I just tried 'macro first($a, $b, $c) { $a }; say first 42, 43, 44' and it doesn't work for some reason :/
not sure I'm awake enough to debug it now.
jnthn soh_cah_toa: It's like if you have a class with an attribute, and really you just want to forward calls on the class to calls on that attribute. 22:58
soh_cah_toa: handles sets up that "forwarding" for you
It can rename too (e.g. expose the method as one name on the class, but then call another one on the attribute)
masak it gives the error `Can not get non-existant attribute '$!past' on class 'AST'`, but there is such an attribute on that class.
soh_cah_toa jnthn: what i don't understand is that method delegation is separate from object attributes 22:59
jnthn: how does a method delegate to an object attribute? that doesn't make sense to me :\
jnthn masak: Maybe a forgotten decontainerization.
masak jnthn: oh!
maybe.
we'll discuss that tomorrow :)
mauke a method on an object delegates to a method on an attribute of that object
jnthn :)
masak dobranight, #perl6 23:00
it feels nice to have the branch pushed.
23:00 masak left
soh_cah_toa interesting. doesn't that make the inheritance tree...weird? 23:00
jnthn nom: class Tail { method wag() { say "wag wag" } }; class Dog { has $.tail handles 'wag' }; Dog.new(tail => Tail.new).wag
p6eval nom 27090e: OUTPUT«wag wag␤» 23:01
jnthn soh_cah_toa: No, it's completely orthogonal to inheritance
mauke soh_cah_toa: I don't think it affects inheritance
jnthn soh_cah_toa: That's kinda the point - it makes doing composition-y OO easy.
soh_cah_toa alright. i'm just not used to the idea of "selective inheritance"
mauke inheritance?
jnthn It's not inheritance at all.
See what I did above.
All it's doing ofr you in that case is writing a method for you, at some level. 23:02
It's like you wrote a method wag() { $!tail.wag() }
But you don't have to; you just say "handles 'wag'" and you get one generated.
soh_cah_toa yeah
it just seems weird to just "inherit" one thing (method) instead of making it a subclass of something or composing a role 23:03
dalek kudo/nom: 698e301 | jnthn++ | src/core/Array.pm:
Optimize array access a little.
soh_cah_toa where you'd "inherit" all methods and attributes
jnthn soh_cah_toa: Huh? Having an object that calls methods on its attributes is like inheriting from the object in that attribute? 23:04
soh_cah_toa i've just never heard of that before. is there any other language that's done that before p6?
mauke perl5 :-)
jnthn No, normally one has to code those things up by hand, or end up mis-using inheritance.
soh_cah_toa ok, not "inteheriting" per se. i mean you're "gaining" behavior from another class 23:05
mauke metacpan.org/module/Moose::Manual::Delegation - probably stolen from perl6
jnthn soh_cah_toa: In a sense though, that's what object oriented programming is about. :)
soh_cah_toa is not a compiler designer and does not know all the fancy pants terms 23:06
jnthn soh_cah_toa: I wish the day-to-day programmer was as aware of composition/delegation as they were inheritnace.
I've seen a few too many mis-applications of inheritance and the resulting mess.
soh_cah_toa i didn't realize there was a difference 23:07
which is your point exactly ;)
mauke a triangle has three points <> a triangle inherits from three points
jnthn mauke: ooh, nice example. :) 23:08
soh_cah_toa i suppose the root of much of my "misinformation" is due to the bad practices college enforces through c++ ;) 23:11

tadzik oh, almost forgot the masak++ :)
soh_cah_toa so what if you have a class Foo that has an attribute `Bar $.foo handles 'bar'` but also defines bar() itself? i'd imagine that it delegates to Foo.bar(), not Bar.bar(), right? 23:16

soh_cah_toa ah...

TimToady overuse of hammer mebbe
too many things looked like a nail... 23:20
jnthn ponders getting the tests it rejects correctly clenaed up, fixing the one or two places it does the wrong thing, then merging it, but requiring --optimize for now.
