quietfanatic Is there a way to concatenate two functions, like Haskell's >> operator? 00:13
diakopter wrap ?
quietfanatic I know sub {&sub1; &sub2} works, but if you do that a lot of times, you get a lot of depth. 00:14
Wrap? Maybe, depending on how it's implemented. But I don't think that's what I'm looking for. 00:15
For one thing, wrap modifies in place
diakopter o
Tene rakudo: sub foo { say 'hi' }; my @a; @a.push(&foo); say 'omg'; .() for @a; 00:16
p6eval rakudo 6c4bab: OUTPUT«omg␤hi␤»
Tene you could do that.
quietfanatic: can you give an example?
quietfanatic Like, I'm writing an event system for my game engine, 00:17
and I want certain events (like collisions) to have a parameter
but of course I can't check every object for every possible collision, so 00:18
diakopter create a global register!! :)
quietfanatic I'd have the object keep a "collision method" and append the new collision code when I register a new collision event.
If I explained that sensically enough. :) 00:19
diakopter sounds like you create a list property on each object that stores its collision events, and the collision method iterates them like Tene said
quietfanatic Yes, I could just have a list of subs. And overload postfix:<( )> on the list. 00:20
Yeah.
diakopter with the argument, if ..
quietfanatic Tene's idea will work fine. 00:21
diakopter .Net has an entire member system for events, though I heard someone say they regretted designating them at that level; they shoulda been just normal members whose slot types are treated as events when they're registered as such. 00:22
quietfanatic I gotta read up more on event implementation anyway. 00:23
diakopter there are scads of techniques of queuing up events on DOM objects
quietfanatic The thing is, I need a really robust system, including parametric events. 00:24
diakopter so make your event method iterator pass in the events as arguments
I mean, pass in the event args as args to the subs
quietfanatic That's not what I mean. 00:25
I mean, the parameter determines when the event gets called.
diakopter you could use the multiple dispatch system for that, or
quietfanatic If I say the ball object has a collision(Brick) routine, it needs to be called when it collides with a Brick and not when it collides with a Paddle.
That's also why I wanted to introspect signatures, by the way. 00:26
diakopter sounds like Collision is a parametric type
on two objects 00:27
I mean, are there 3-body collisions?
quietfanatic They happen, though coding them would be a pain. 00:28
What I'm doing for now is I don't have collisions as events, but as normal checking in other events. 00:29
diakopter do you have a Movement event?
quietfanatic Yes, it's called move.
diakopter is it a sub or a 'data' object 00:30
quietfanatic The collisions would be checked after that event.
It's a data object, that calls the object's move method.
Actually, it's onbly kind of a data object.
00:30 rhr left
quietfanatic What happens is, when registering the event, I put the object class into the event's queue, rather than putting the event on the object somewhere. 00:31
00:32 rhr joined
diakopter do your objects use a discrete 2D grid when detecting collisions and calculating movement, or some kind of relative proximity checking to other objects 00:32
quietfanatic They're effectively rectangles, so it's easy to check their positions against eachother even though the grid is not discrete. 00:33
Doing collisions based on a bitmask will be fun and tricky. (and slow)
diakopter I don't know.. assuming there's no superposition of objects' "centers", seems to me it'd be faster 00:34
quietfanatic No, I mean checking each pixel of the object's image (or mask or something) to see if they overlap.
diakopter oh, rather I'd think each object would register its boundaries into an array of arrays that represents the pixel grid 00:35
quietfanatic Oh. If I used integer positions, that'd be possible. 00:36
diakopter and each movement would check whether the movement would cause an overlap..
right, integer aka discrete 00:37
quietfanatic In fact, it would even be easier if I was writing my own graphics library.
Yeah, integer = discrete, but I'm using Nums.
diakopter runs. at least they're not bigints or smth :) 00:38
quietfanatic The only thing that bothers me about Nums here is that they have higher accuracy toward the top-right of the screen :)
I mean top-left
diakopter where's the origin 00:39
quietfanatic If somebody inplements a fast fixed-point data type, I'll use it.
The origin is in the top-left.
diakopter k
so each objects' movement is turn-based
quietfanatic Yes-ish. 00:40
diakopter so with 50 moving objects, each contributes toward computing the state that will determine how to draw the next frame?
quietfanatic I'm thinking that unless a specific turn order is specified, the objects will be moved in parallel.
Um, yes, I think? 00:41
diakopter I think that's what you mean by in parallel
each object's individual movement doesn't get its own frame redraw
quietfanatic No.
All objects move, then all objects are drawn. 00:42
diakopter that's what I was saying
quietfanatic (skipping over after_move events and such)
Well, I've got to get to class now. Be back this evening. 00:44

htns Hi. Never used IRC before. Hope this works... 01:59
Just built Parrot and then Rakudo. 02:00
Ran a simple script (say "hi", count to 10), and `time` tells me it took just under 5 seconds.
Is that about right right now for Rakudo on Parrot? 02:01

htns_ Then got Rakudo from svn.

Built and installed fine.
Didn't want to have Rakudo get Parrot. Wanted to do my own Parrot installed and all set, *then* get Rakudo.

diakopter htns_: that's b/c "Perl 5 by default" is not yet implemented in Rakudo 02:22
02:22 msmatsko joined
htns_ Rakudo on Parrot will, by default, assume code in .pl files is Perl 5? 02:22
diakopter if someone implements that, yes.. :) which I assume is the plan since that's part of the Perl 6 spec. maybe not by Rakudo Star though? 02:23
colomon I don't recall hearing any mention of that at all this year. 02:24
02:24 rhr_ joined
diakopter mention of what 02:24
colomon I had been figuring "use v6;" was so Perl 5 knew not to try to run the file.
Perl 5 being on by default for Rakudo. 02:25
htns_ I'd assumed something like that as well.
diakopter yeah, but Perl5-mode-by-default is still part of the speculatifications
htns_ S01 says "Migration is important. The perl interpreter will assume that it is being fed Perl 5 code unless the code starts with a "class" or "module" keyword, or you specifically tell it you're running Perl 6 code in some other way, such as" 02:26
diakopter yeah
colomon diakopter: not saying you're wrong about that, just that I haven't heard any recent mention of making things work like that.
htns_ s/perl interpreter/perl 6 interpreter/ ?
diakopter well, perl, since it's both 5 & 6 02:27
so *presumably*, a fully to-spec implementation would be a drop-in replacement
I'm not presuming that part of the spec won't get de-idealized :) 02:28
htns_ Oh, I see. I didn't realize that Rakudo + Parrot was intended to be able to be used as a drop-in replacement for my Perl 5.
colomon it's really kind of insane, isn't it? I mean, implementing Perl 6 is already hard enough. Asking every implementor to add the entirety of Perl 5 as well seems over the top. 02:29
diakopter well, pmichaud (but it applies to every implementor too) was writing somewhere recently that [extremely paraphrased] rakudo (substitute: each implementation)'s spec coverage progress would continue, and if it reached the totality by eternity, then so be it 02:30
and he was also willing to draw a box around a particular set of features and give it names/labels/version numbers 02:31
and even eventually call it "stable", if not "finished" or "fully to spec" 02:32
colomon: well, by doing interop/bindings/linking/hosting with Perl 5, pugs was able to achieve *quite* *a* *lot* toward that goal 02:33
but then again, messiahs advent only a few times per eon. er something
htns_ I'm still trying to fathom totality by eternity. :) 02:34
diakopter oh, the unfathomable depths...
02:35 rhr left
Tene Jonathan and a couple of others are working on integrating the Perl 5 interpreter as a language on Parrot. 02:38
The project is called Blizkost.
htns_ I remember reading about it when Rakudo was removed from Parrot proper. Have all the parrot languages been removed? 02:39
Tene Yes.
diakopter colomon: but yeah, it's daunting. :) 02:41
htns_ Ah. I see. All the languages listed on the parrot site now link to wherever they are now hosted.
The Parrot certainly lost a lot of weight there. ;) 02:42
Tene Yes.
colomon moritz_: I haven't actually tested it yet, but I think the current changes ought to make the named argument trig tests which are currently skipped work... Errr... but I haven't pushed the changes yet, still running spec test to make sure they don't break anything. If I'm up in the middle of the night I'll push them. 02:43

I don't.

*probably needs
moritz_ pmichaud: plan *; is an option, not a requirement
pmichaud sure, but 01-sanity is intended to be "the minimal features needed to parse most of the tests"
moritz_ pmichaud: and for the 01-sanity suite I'd continue using planned tests 14:30
pmichaud that's not what 01-sanity does
moritz_ uhm, it's not been that for ages :/
pmichaud 01-sanity is the tests needed to say "okay, you have enough features to run Test.pm"
01-sanity doesn't itself use Test.pm

pmichaud s/"parse most of the tests"/"run Test.pm" 14:31
moritz_ well, that's what you thought in the initial stages of building rakudo - if my memory serves right then it didn't work that way in reality
pmichaud right, because nobody kept 01-sanity up to date with Test.pm :)
moritz_ and also there's not one Test.pm
pmichaud but when we re-implemented Test.pm, I at least made an effort to not use features in Test.pm that weren't tested in 01-sanity
or to add things to 01-sanity that were needed for Test.pm 14:32

colomon I think if you just submitted a rakudobug every time you were tempted to respond to a tweet like that, it might have better results on the whole. :) 15:13
huf i guess this is like the french not bathing. 10 milennia from now ignorant people will still claim the french dont bathe and perl is unreadable and perl6 will never be finished... 15:14

15:14 jan__ joined
pmichaud sometimes it's best to simply embrace the insanity :) 15:14
colomon masak: I bet if you gave yourself ten minutes to find a rakudobug, you could do it every time. 15:15
moritz_ or ignore it ;-)
colomon It just seems to me that, if we do our jobs well, these guys will be forced to eat crow in about eight months. 15:16
masak Twitter is a great place to actually spread the word about Perl 6. providing factual, sometimes tongue-in-cheek answer to a selection of taunts or false rumors can, I believe, have results.
Matt-W Mmm 15:18
It is a good strategy - if you can come up with a reply of the right kind of tone
you don't want people to think you're flaming
masak exactly.
colomon I guess I'm thinking about a conversation I had a couple of weeks ago at a bachelor party.
masak you were discussing Perl 6 at a bachelor party? :)
colomon The groom mentioned that one of my Facebook statuses had been about working on Rakudo. 15:19
Matt-W :)
colomon And one of the other guys, it turns out, used to be Perl programmer, but has fallen into (I think) PHP.
Matt-W adds to the list of ideal items for the perfect fantasy wedding: camels and onions and butterflies
colomon And he reflexively made a crack about Perl 6 taking forever to come out. 15:20
Matt-W I always find it amusing when PHP programmers mock Perl 6
And also quite saddening
The poor people
colomon My response was about how well Rakudo is coming along.
But if we're honest about it, right now it still isn't production-ready.
Matt-W of course not 15:21
colomon It's getting really close, but it's not there yet.
Matt-W But we're going to be
quite possibly in 2010
masak just going to close those bugs first...
colomon That's what I'm saying. If Rakudo * does its job, Perl 6 will have a reasonably production ready platform.
It might not be "done", but it will be very useable, I think.
At that point, responding to the naysayers will be almost effortless, I think. 15:22
and a lot more convincing.
That's my theory, anyway. I'm not saying we shouldn't try to tell people what is going on now -- but we should be putting our money where our mouths are and making it actually happen. 15:24
justatheory hugs colomon
colomon Of course, masak is a champ at the latter!
masak for better or worse, I care. 15:25
Matt-W I care too
masak but I also do it because I want to see cool things happen, and the easiest way to do that seems to be to write code, write blog posts and file bugs.
Matt-W I just don't have many tuits

actually, it's not even that bad.
Matt-W Unfortunately my day job sucks up a lot of tuits
masak but I am working half-time because I want to spend large parts of the other half on Perl 6.
Matt-W and my other hobbies suck up even more - but if I didn't do hobbies that weren't programming, I'd go mad 15:27
moritz_ aye, it's important to do something else
3x table tennis next week ;-)
Matt-W programming for a living can be soul destroying
yay table tennis
masak goes swimming 15:28
Matt-W I do aikido
masak and every time I do, I look at the tiles at the bottom of the pool and think about Druid. :)
Matt-W And play the recorder, viola de gamba, lute and sing
hahaha
moritz_ the problem with table tennis is that it requires a lot of concentration 15:29
Matt-W yes but it's a different kind of concentration
moritz_ so it's not such a good way to switch off your brain and let your body work
Matt-W no
swimming's better for that
you can just swim up and down and up and down
I used to go swimming and think about writing
masak I used to do swing dancing. I still run occasionally. I have a secret urge to do bicycle spinning. 15:30
Matt-W these days I tend to do that while I'm walking, or I think about composing music - the trouble with the latter being that I tend to forget the tune I was thinking about by the time I get home and can write it down
bicycle spinning?
masak Matt-W: I don't know if that's the term.
Matt-W: we call it 'spinning' in Sweden. it's a form of exercise. 15:31
Matt-W: for tunes, I have a music player around my neck at all times with a recording ability.
Matt-W: but unfortunately, I never sit down and compose from those recordings... :/
hm, "Indoor cycling" seems to be the term. "Spinning" is a trademark. 15:32
Matt-W hmm 15:36
my phone now has a sound recorder on it
but last time I really had a tune I really wanted to record, I was on a very windy hillside 15:37
never did get that one back :(
masak: heh, good tweet
masak directed to everyone and no-one.
15:40 snearch left
colomon I've always figured that if I can't remember a tune by the time I get back home, it probably wasn't worth remembering. :) 15:40
Matt-W I'm not so sure about that 15:41
masak I've sometimes carried tunes all the way home by humming them over and over.
Matt-W I get distracted a lot
colomon (But then, once I get back home I try to record it pretty quickly, so maybe that's just an excuse not to get a digital recorder I can always have with me.)
Matt-W and I usually do a lot of revision over the base concept anyway
what usually comes to me when I'm at an inconvenient moment to do anything about it is the first phrase
so then I have to do any subsequent parts the hard ware
way*
but it gets me moving in the right direction
Matt-W -> out of the office, anywhere but here 15:43
colomon Ah, the advantage with Irish Traditional Music is that tunes are so simple that not a lot of revision is called for. ;)
Getting back on subject, I'm finding that working on Rakudo is a powerful reminder that I used to program for fun. 15:45

diakopter sprixel: sub foo( &foo = &foo ) {}; foo
p6eval sprixel 28546: ( no output ) 15:53

diakopter sprixel: sub foo( &foo = &foo ) { say 4 }; foo
p6eval sprixel 28546: ( no output )
diakopter heh
masak colomon: they appear as a by-product of actual coding, most of the time.
colomon masak: I know, I know. Though it sometimes feels like ten minutes of uninhibited Perl 6 programming will produce a Rakudobug for sure... 15:54
masak not so sure about that.
it was definitely true by the end of 2008. 15:55
diakopter rakudo: sub foo( &foo = 1 ) {}; foo

long bike ride & 15:57
colomon Errr... anyone out there know what is supposed to happen with a "fail"? 15:58
Complex.Num calls fall if the imaginary part of the number is not zero -- but it seems to effectively be returning 0 as well. 15:59
I get the fail message if I call it from the REPL, but just get a normal value isn't correct error in the test file. 16:00
Seems like that could have very bad effects in practice.

colomon I think it is divide by zero, actually; we don't trap for that if I recall correctly. 19:22
We can do "math" on the Rat 0/1, but it is unprintable. 19:23
ruoso pmurias, "interpreter" really means "thread" there
19:23 keeth left
ruoso pmurias, we're going to have one "interpreter" object for each thread of execution (being it os thread or not) 19:23
lanny 1/0 you mean? I hope we can do math on 0/1
19:24 keeth joined
colomon lanny: 1/0, yes. 19:24
lanny: the math on the 1/0 is reasonably sensible, I just balk a bit because it allows you to do terrible things. 19:25
lanny colomon: most programming languages live in the real world though where 1/0 is an error to avoid small problems become big ones down the line 19:26
colomon lanny: but it's not a problem that goes away. 1/0 is tracked more or less the same way setting Inf or NaN would be. 19:27
pmurias ruoso: thanks 19:28
colomon though... hmmm...
lanny colomon: then numerator and denominator should probably be set to Inf
colomon rakudo: say 1 / (1 / 0);
p6eval rakudo c4dbb5: OUTPUT«0␤»
colomon rakudo: say Inf / Inf 19:29
p6eval rakudo c4dbb5: OUTPUT«NaN␤»
lanny ah. well then Inf / 1
colomon rakudo: say 1 (Inf / 1);
p6eval rakudo c4dbb5: OUTPUT«Confused at line 2, near "(Inf / 1);"␤in Main (src/gen_setting.pm:3468)␤» 19:30

Ok. How do you get the number that a Class Num is from inside a method? self and +self aren't doing what I expect. 19:32

DeathAnchor Question, what do you use for SVN client on a Win32 system?
lanny Ah. Q:PIR 19:35

colomon lanny: self should work just fine. 19:36
lanny DeathAnchor: I've heard TortoiseSVN mentioned before.
colomon: is probably me then.
DeathAnchor gah, I hate tortoise. The gui is junk. I guess i could just use the commandline for it. 19:37
19:37 takadonet left
colomon lanny: you definitely shouldn't have to go into Q:PIR unless your code is actually in PIR. 19:37
DeathAnchor was hoping for something better, but alas is disappointed.
lanny colomon: I'm tempted. One sec while I nopaste it and maybe you can see where I've gone wrong. 19:38

lanny typo on 'rakudo' 19:43
colomon I wonder about self versus +self, but it sounds like you tried both?
lanny I did.
colomon rakudo: class Num is also { multi method Rat(Num $epsilon = 1.0e-6) { say self; }; }; 1.0.Rat;
p6eval rakudo c4dbb5: OUTPUT«1␤»
lanny Tried 'self' first and then noticed method Str { ~self } so figured to try +
colomon lanny: unfortunately I've got spectest running, so I can't just pry open Num.pm and insert your code. 19:44
lanny How very odd. What I'm seeing after compiling is (exp(1)).Rat.perl.say gives no output
colomon: no worries. 19:45
colomon but I don't see any obvious problems with the $num = +self line.
insert some say statements in there and see where the code gets to?
diakopter pmurias: V8's runtime can thread across cores, but you can't access it from JS with the default build. In the browser, Chrome can thread across cores, but all interthread communication has to be explicit across DOM frames (tabs) :) 19:46

lanny Rather than a becoming a / 1 and doing the cross multiplication 19:52
colomon BTW, spectest finished, and I'm compiling your code as we speak. 19:53

colomon lanny: as far as I know, named args don't work at all at the moment. at least, I've had several fails with them in the last 24 hours.
I should have noticed, but it seemed like the Rat.new was the safe part of your code. :) 19:57

colomon oooo... when I do pi.Rat.perl, I get 355/113. Shiny! lanny++ 20:02
lanny Yeah. Debating if I want to go the distance for the first best-rat-approx within $epsilon but it's more code so thinking this is good enough 20:03
colomon seems like a heck of a good start, at any rate. 20:04
lanny Well it's using the continued fraction expansion. At some point on my plate is to write a CE class. Got most of the way in haskell and then life got busy. 20:05
colomon A pity I didn't have this when I was working on the Rat trig tests, it would have come in handy to get a highly accurate rational approx of pi.
lanny The CE expansion is guaranteed to be a best-rat-approx. Just not necessarily the first closest.
