pmichaud colomon / sorear: fail() returns a Failure value containing an unthrown exception. If the returned Failure isn't marked as handled somehow, any attempt to use the Failure as a normal value throws the exception. Essentially, fail() is a soft failure ("return something that throws an exception if you attempt to use it"), while die() is a hard failure ("throw an exception immediately"). 08:03
phenny pmichaud: 25 Apr 21:53Z <moritz> tell pmichaud basing a star release on rakudo 2012.04.1 seems to give star the version 2012.04.1 too. Should we try to separate that? or just go with it?

jnthn Yeah. I doubt that's the actual bug here though. 11:21
moritz @.slots.push([$sender, $rcpt, $method]);
masak it isn't.
moritz that shouldn't ever work
because @!slots is typed to contain Method objects
and you try to push an array on it
jnthn Wow, yes.
gfldex i changed &$signal to $signal, still Null PMC
masak still, that's not the bug either.

gfldex i don't think i can golf it much
masak tries, then
moritz the weird thing is, it explodes while invoking method pressed 11:25
gfldex yes and it calls the wrong handle_call 11:26
moritz but nothing seems to override its invoke/postcircumfix:<( )>
jnthn That &wrap call means you are wrapping with the proto.
moritz oh, erm, does .wrap on a method work at all= 11:27
s/=/?/
jnthn And that trait_mod along with the multi, proto etc. has to be compiled "just in time" since the trait_mod runs at BEGIN time.
Yes, .wrap is defined on Routine.
moritz r: class A { our method x { say 'A.x' }; }; BEGIN &A::x.wrap( sub(*@) { say 'OH WRAP' }); A.x 11:28
p6eval rakudo a25e7d: OUTPUT«===SORRY!===␤Unable to parse postcircumfix:sym<( )>, couldn't find final ')' at line 2␤»
gfldex my guess is that the dispatcher is calling the wrong handle_call with a capture that is empty but not
11:28 oiig_ joined
jnthn But a $m should be in scope and not null in either case. 11:28
moritz r: class A { our method x { say 'A.x' }; }; BEGIN &A::x.wrap( sub (*@a) { say 'OH WRAP' }); A.x 11:29

p6eval rakudo a25e7d: OUTPUT«OH WRAP␤A.x␤»
jnthn gfldex: multi handle_call {
In this case, that candidate can never match.
Because a method *always* has at least one argument. 11:30
gfldex well, $m seamt to be null
jnthn Yeah, it shouldn't be.
gfldex i added say $m.elems; and it explodes
jnthn I suspect it's some kind of lexical chaining issue.
masak $m.WHAT says Method+{Signal}() 11:31
gfldex s/i added say $m.elems; and it explodes/nvm/ gfldex--
actually say $m.slots.elems; explodes 11:32
jnthn masak: Not if you do it inside of the multi handle_call
masak oh! 11:33
jnthn OK, it's the multi that is somehow to blame
masak Can only use get_what on a SixModelObject
gfldex if i say multi handle_call in the trait_mod multi, does it create a clousure?
masak yeah, that feels like a lexpad outer chain corruption.
jnthn gist.github.com/2518209 gets much further 11:34
masak: Yeah, something along those lines.
masak submits rakudobug
moritz adding a proto also gets much further

gfldex because |$args should be empty 11:40
jnthn masak: Uncommenting the proto explodes
gfldex: It will never be empty because you're wrapping a *method*.
GlitchMr: You'll always have at least one argument.
er
sorry, that was for gfldex :)
gfldex so i have to strip the first argument?
jnthn Well, the first argument is the invocant.

12:36 sergot joined
moritz gfldex: you're probably right, and it's simply my infamiliarity with the whole system that makes me wonder 12:37
gfldex and it would be nice to have class Foo { signal pressed; }; class Bad { slot exit() { $*GLOBAL::exit }; my $a = Foo.new; my $b = Bar.new; connect($a.pressed, $b.exit);
so there would be at least some macroing needed if not some grammar-foo
and i'm eager to get there :) 12:38

mucker o/ #perl6
gfldex because &Foo::bar would return Nil (or nil)

gfldex i could do that if i have unhygienic macros 12:54
or maybe not
12:55 laurus left
jnthn will wait for the gfldex++ blog posts and then comment :) 12:55
(I'm not familiar with the signals/slots thing either.)
gfldex if i go connect($obj1, 'method1', $obj2, 'method2'); i get the error message for a typo at runtime
that's exactly the problem with qt's moc 12:56
the connect happens at runtime and you get the typecheck and lexical check late
the advantage is that it works inbetween different processes
masak "unhygienic" !=== "operates on text rather than ASTs" 12:57
gfldex masak: i am most sorry to have hurt your macro feelings :)
so you can call a slot in a c++ application from the bash
that includes all kde apps 12:58
all you have to do is to write: slot void my_method(){};
and that slot is even an empty macro :)
masak gfldex: no hurt feelings, just trying to improve the general public's understanding of macros ;) 12:59
ASTness and hygiene are two distinct levels of purity.
if it made sense to talk about pure textual macros -- maybe it does, though I doubt it -- you could combine textual/AST and impure/pure all four ways. 13:00
gfldex i would rather not, macros are confusing as they are :)
masak the point of textual macros is that they can ignore or span boundaries easier than AST macros. they're sloppier, and harder to analyze. 13:02
but they can certainly have a lexically scoped influence, and indeed I suspect they will in Perl 6.
13:03 mucker left 13:04 mucker joined
masak but there's nothing that stops a textual macro from inserting the variable name '$' ~ whatever() at a point -- and getting hygiene from that, well, hm. could be it comes down to solving the halting problem, actually. 13:06
hm, no. it's simpler than that. 13:08
what we *want* from that text insertion is unhygiene.
so they're not compatible, and by design.

jnthn arnsholt: My plan is that Zavolaj will just do $cap ~~ $sig at some point.
Apart from I didn't implement Signature.ACCEPTS(Capture) again yet.
jnthn should really get around to that.

15:52 Patterner left
moritz fwiw the logic is there already, somewhere 15:52
jnthn moritz: Is it? :)
TimToady I dunno, it seems like the sig should be involved in marshalling the args
jnthn moritz: If you mean "do what ng did" then NO NO NO NO 15:53
TimToady: It's introspected and used to feed the marshaller.
moritz the MAIN helper checks if any MAIN can be called with a given capture
15:53 spaceships joined
TimToady introspection == design smell 15:53
jnthn TimToady: This is EXACTLY THE RIGHT USE FOR IT.
It basically does a .params.map to map them towards the thing the NQP NativeCall stuff in C land wants as in put. 15:54
*input
TimToady so why can't the marshaller check it then
jnthn It could, it's just duplicate work.
TimToady so's calling ACCEPT
jnthn As in, we shouldn't implement signature binding in the marshaller, it just call .ACCEPTS to do it. 15:55
TimToady maybe we're in violent agreement here
jnthn No, the design of what's there now assumes that "I have a Capture in the right shape"
What we're missing is asking the signature "do you accept this capture"
jnthn did design these pieces to fit together :) 15:56
TimToady tries to figure out some other way to torment jnthn++
jnthn TimToady: While we're on this though...guess I can ask something useful: would you expect a Signature to always be mapped back to a scope that it's a signature for? 15:57
At the moment, I have a Code Object -> Signature reference.
Should there be something back the other way?
TimToady depends on the declarator, I'd think 15:58
jnthn If yes, then the main implication is that a signature literal in code also implies generating a hidden-away Code object.
TimToady a bare :() doesn't map to anywhere
a my () does
jnthn If it does that, then we have a lexpad in the right shape to feed the signature binder to.

jnthn Recursive descent in the traditional sense doesn't do any of the declarative prefix / LTM stuff. 16:20
arnsholt There's that as well
TimToady I think the real underlying point is that you can parse a single language faster than many languages, but this is taking the lesson backwards. 16:21
lalr and such is a useful optimization for a given langauge
but our problem is that we're recalculating the set of languages over and over
as a degenerate case, if you know the language hasn't changed, and the program hasn't changed, you can compile instantly 16:22
arnsholt True, true. Also the horrid horrid error reporting characteristics of LALR, if you ask me
TimToady partial recompilation is another way to slice it
yes, error reporting was a big reason, but that doesn't prevent it from being a useful optimization 16:23
you just regress to recursive descent if the bottom up fails
arnsholt Oh, that's a nifty idea 16:24
But I'm not sure I'd want to implement it =)

What does a type object actually have?
In that case, yes, just the stuff in SixModelObjectCommonalities.

I mean, complex numbers are just numbers on the form a + b sqrt(-1), right?
could one create a custom class representing numbers on the form a + b sqrt(5), and define addition, multiplication, and division such that one never has to use floating-point numbers to calculate fibonacci numbers? 19:41
19:42 preflex_ joined
moritz knows an integer-only representation that can calculate fibonacci numbers :-) 19:42
colomon you can certainly create a class representing numbers of the form a + b * sqrt(5)
19:42 eviltwin_b joined, preflex left
moritz masak: the problem is just that raising a number to the power needs seem kind of iteration 19:43
19:43 preflex_ is now known as preflex
masak that's fine. 19:43
moritz masak: so calculating that power boils down to the well-known iteration formula, if you are lucky. And to something more complex in the worse case
masak nod. 19:44
it's a mental exercise, not an optimal solution.
colomon is very fuzzy on how a + b * sqrt(5) is useful in this context, though....
masak colomon: all terms in that formula are on that form.
moritz modulo the /2 at the end :-) 19:45
masak no, that's also on that form :)
oh wait.
yeah, I see what you mean.
19:45 geekosaur left

(this is inspired by github.com/raganwald/homoiconic/bl...bonacci.md , by the way) 19:46
colomon it doesn't really help, does it?
(I mean, adding halves) 19:47
moritz right, you need to store numbers of the form (a + sqrt(5) * b ) / 2**c
masak oh, indeed. 19:48
so its representation is a triple...
colomon but it's not closed or anything like that, is it?
masak yes, and that's my point. 19:49
(but I missed the /2)
colomon I mean, multiplying two Fib numbers doesn't necessary give you another Fib
masak no, but this field is bigger than just the fibs.
moritz but adding two gives you one :-)
erm, not always
never mind :-)
masak :P
(a + bq)(c + dq) = ac + adq + bcq + 5bd = (ac + 5bd) + (ad + bc)q, and the latter is also part of the set. 19:50
19:50 aindilis joined, xinming joined
masak so these Q numbers are closed under multiplication. 19:51
the above again ignores the /2**c, but you can add it in and it'd still be closed, since it's just a power of 1/2.

sorear there's a nice optimization of the matrix approach - the calculation never leaves a 2-dimensional subalgebra spanned by the initial matrix and I

colomon: better method names welcome :-)
masak I think .Int would've been fine in the end, since it's custom for the class ;) 20:09
what does AN stand for?
moritz but it's not the int representation of that number
colomon AFK 20:10
moritz my previous method name was Int-by-div-sqrt5
sorear What if, instead of the ring Q[sqrt(5)], you used Q[phi]? 20:11
masak ok, I see.

moritz tadzik: just a complicated way to calculate fibonacci numbers :-) 20:15
tadzik eek
well, 46 lines > 10 characters :)
moritz blames masak
masak hee hee
tadzik :)
moritz masak: oh, and for calculating fibonacci numbers you can actually leave out c 20:17
masak oh! yes.
moritz in this calculation, b == 0 mod 2 ** (c -1) always holds
masak nod. 20:18
hm, phi**2 = (1 + q)**2/4 = (1 + 2q + 5)/4 = (6 + 2q)/4 = (2 + 2q)/4 + 4/4 = phi/2 + 1
so (a + b phi)(c + d phi) = (ac + bd) + (bc + ad + bd/2) 20:19
interesting algebra :)
er, last paren times phi, 'course.
(a + b phi)(c + d phi) = (ac + bd) + (bc + ad + bd/2) phi 20:20
colomon tadzik: you need to regenerate the Emmentaler page -- I keep on fixing modules. ;) 20:23
tadzik hehe, right
you can run it too :) 20:24
moritz how long does a run take?
tadzik <20 mins on my laptop
colomon tadzik: you shouldn't be tempting me to make it a local cron process. 20:26
tadzik I don't need to. You already want it :) 20:27
jnthn Where was the Emmentaler page again?
Is it somewhere pernament enough we can link to it from modules.perl6.org?
moritz or I can make cheese.perl6.org redirect to it 20:28
jnthn \o/
tadzik it's currently tjs.azalayah.net/new.html, but it's just a place where I scp an html file
I should move it to its repo 20:29
I should have a handful of tuits tomorrow

uvtc Earlier I was asking about running `perl6 --doc=html ...` in a sandbox to generate docs for modules.perl6.org. I've been learning Clojure, and wrote a little script to do something for clojure libs (but in Python). It's at <github.com/uvtc/petit-lorange>.
tadzik yeah, seen that
sandboxing is probably the way to go, yes
dalek Iish/mysql-prepared: a138cc5 | (Tore Haugland)++ | t/10-mysql.t:

tadzik after integrating Emmentaler with modules.perl6.org somehow the next plan is to add some documentation to it as well 20:44
masak yay
uvtc regardin Emmentaler, I think the table would look nicer (it would be wider) if the camelia logo had a <br/> after it.

tadzik, what does "Emmentaler" mean?
tadzik uvtc: it's a kind of cheese

phenny: tell uvtc that in my second talk ever, masak.org/carl/npw2009-november/talk.pdf -- I used a metaphor with Rakudo being a cheese with holes that we find by running the spectests, or by writing applications. this led to "Rakudo cheese" and "app cheese" being synonymous with testing Rakudo and the app space, respectively. hence, Emmentaler. 20:50
phenny masak: I'll pass that on when uvtc is around.
masak that talk is probably still my most appreciated talk, ever. I don't know how that happened. 20:51
I think it's because the audience was sitting really close, and it became cozy-like. 20:52
jnthn remembers that workshop :) 20:54
It was on the top story of a fairly tall building.
So there was a nice view.

And then there was the rooftop beer party... 21:05
masak hm, I musta been not drinking beer back then. 21:06
but I remember Gloria. :)
she had TimToady whistle. :)
lichtkind_ mst rocks
i like him
masak deep inside mst, there's a very nice person... because mst ate that person. :P 21:07
no, he's a hoopy frood, srsly. I just don't think he'll ever be a Perl 6er. 21:08
I'm willing to be proven wrong, though.

gfldex i iz propaganda cat i tellz troof: gfldex.wordpress.com/2012/04/28/sig...-the-pros/ 21:39
masak gfldex++ 21:41
gfldex: that last bit of wish-code 'connect(&$input.sig_changed, &$data.set_age);' makes no sense whatsoever. 21:44
if I were you, I'd remove it from an otherwise excellent post. :)
jnthn masak: gfldex++ is hungering for a nice way to do a method dispatch but not actually dispatch, just get what we would dispatch to, I guess. 21:45
masak yep, I get that.
gfldex i will leave it or i will forget about it
masak but the syntax he proposes is insane :)
it... I...
jnthn masak: :)
masak: Relax. :)
gfldex i'm not going to force you to use that syntax
jnthn masak: We don't actually *have* a good syntax for it at the moment though.
masak right, I know. 21:46
but that's not gonna be it, I can tell you that.
jnthn The right way involves a .^find_method
No, there's a lot of reasons why it can't be the one in the post.
gfldex connect($sender, 'signal', $receiver, 'slot'); # is ugly 21:47
masak I hear ya. 21:48
diakopter I'll send your slot
masak gfldex: as an interim, you could define a class which holds an object and a method name. 21:49
and then an operator which creates that pair.
gfldex one thing I found strange (beside the segfault) is that when I do connect($obj, &Obj::wrong_method_name, $obj2, &Obj2::wrong_too);# rakudo complained fairly late
masak connect($sender :. 'signal', $receiver :. 'slot') 21:50
21:51 Patterner left
jnthn masak: Weren't we meant to be making it less ugly? :P 21:51
masak or, hm, you could mix in a role to all classes that overrides postcircumfix:<( )>
connect($sender<signal>, $receiver<slot>)
I don't think it gets much prettier than that ;)
jnthn omg...
gfldex connect($sender, signal, $receiver, slot); # is something i would be happy with and what works with Qt thanks to the formidable c preprocessor 21:52
jnthn You can do that with a textual macro I guess.
gfldex that's how they do it
masak yeah. I'll have no part in it.
jnthn masak: Oh come on, you know you want to... :P
21:52 Psyche^ joined
masak I'm not insane enough yet to want it. 21:52
but I meant, I don't think it's a good solution API-wise in this case. 21:53
or most of the time, really.
gfldex $receiver<slot> would either involve macros too or require changes to the slot
masak it breaks Least Surprise in a big way.
gfldex and i actually like it that you don't have to do anything at the slot side
jnthn Yeah, I like the loose coupling in this.
masak I didn't follow the bit that says it involves macros or requires changes to the slot. but never mind. 21:54
gfldex you either untangle $receiver and <slot> with a macro or you mixin postcircumfix:< < > > (or however that is spelled) into the slot 21:55
what would be easy ofc 21:56
