grondilu made a joke on rosettacode.org/wiki/Self-hosting_compiler. I hope that won't bother anyone or anything ;-) 09:05
I was trying to be sarcastic though, because the idea of self-hosting compiler is not trivial, and 'eval slurp' really is a Perl 6 compiler written in Perl 6. 09:08
masak grondilu: maybe I'm a bit picky, but that does not qualify as a "self-hosting compiler" to me. 09:11
grondilu it's more of an interpreter than a compiler if that's what you mean. But there's not much difference. 09:12
masak if someone asks you to implement binary search, and you call a function that does binary search, you have not implemented binary search. 09:13
if someone asks you to implement a self-hosting compiler, and you call 'eval', you have not implemented a self-hosting compiler.
grondilu masak: if to implement a language you're allowed to use parts of that language, then there is no reason to exclude any of these parts. 09:14
moritz the specs don't mandate that the compiler must be self-hosting; so a call to eval might or might not call into a self-hosting compiler 09:16
vendethiel (shouldn't that be EVAL ?) 09:19
grondilu oh yeah I forgot about the change in casing
09:20 anaeem1 left, anaeem1 joined
nwc10 also, semantics here, isn't the question "implement" rather than "provide"? ie implied is "not using a builtin" 09:20
masak my point. 09:21
grondilu everything at some point calls a builtin.
nwc10 yes, agree, your point, but I was trying to be annoyingly clearer (and probably failing)
masak yes. thank you. :) I'm glad someone agreed. 09:22

lizmat BenGoldbeg / moritz: the reason I called it first-rindex, was because of rindex on strings 12:18
last-index actually makes a lot of sense to me, I just didn't think about it that way

look how it stringified Int in that context, but not in the first one
skids I updated the gist. Switching to my %store{Any} still metastable. 16:38
timotimo ah, that's not good 16:39
can you output the contents of the hash a bit more precisely?
perhaps even with .DUMP?
skids I can try, but depending on where you put the "say" the bug will dissapear. 16:40
timotimo hah! :)
that sucks
skids Well, I can get the bug to happen while saying %store.keys, and they stringify to C.new(), and I say they because sometimes there are two which should not happen. 16:52

thou I think I spy an obscure typo in S05:1884; Need a space before foo in: / (<* <foo bar baz> >) / Otherwise <foo bar baz> is parsed as <foo(/bar baz/)>, and intention is to parse it as [ 'foo' | 'bar' | 'baz' ].

thou Can anyone confirm I'm reading the spec right?
timotimo but it's inside <* > 17:28
does that make a difference?
skids (The reason for the object hash is just a workaround for the diamond composition problem, and will go away eventually)
thou Not as I read it. "A leading * indicates that the following pattern allows a partial match." -- <foo bar baz> is interpreted as a pattern. 17:29
timotimo oh, ok 17:30

i'm still wondering what we'd need to do to get .WHY on most things in the setting if we have a repl session 18:29
tadzik there was an idea to lazy load them from what p6doc uses
because putting all the things in the setting would be meh 18:30
maybe one day we'll be so fast and tiny that it won't be :)
but now, /me is building rakudo-jvm to see if he can afford more than one bullet in his game until collision detection becomes unbearably slow 18:31

raydiak pleasant prenoon, perl people 18:36
tadzik hello raydiak 18:37
raydiak \o tadzik...working on cool game stuff?
tadzik yep :)
I've sort of hit the performance limits
and it makes me sad
because even if I use proper and clever algorithms it will still be too slow, I estimated 18:38
so I have to drop lots of things to C
at which points it makes more sense to just have box2d do it all
which is probably a good idea anyway
raydiak yeah me too...was going to enter that contest, but only got through the window to run at a single-digit FPS 18:39
tadzik but I'll definitely write some pure-p6 benchmark related to it, so I can notice if one day it becomes alrighty fast
uhh, really?
raydiak aye
tadzik that shouldn't happen
what machine is that?
raydiak even on half-decade+ old laptops?
tadzik ah, hm
I could check that on my half-decade old laptop :P 18:40
FROGGS tadzik: even Perl 5 was too slow to do things in P5 directly
tadzik or on that P4 computer nearby
FROGGS: wow, really?
even with proper quadtrees and all that? 18:41
FROGGS yes, that is why I wrote that LayerManager in XS for example
tadzik hm :) That boosted my morale a bit
FROGGS no quadtrees involved, but we calculate only the areas that have changes, so there is less to update on screen 18:42
tadzik but really, I have a pretty good i5 in this laptop, and it can't really handle checking one bullet against 20 ships in reasonable time
FROGGS changed*
tadzik so I don't think that building a proper tree and all that will make it any better
if it can't handle 120 &infix:<<=>'s basically
but well, for this week I have animations, gamepad support (if it's the xbox pad) and more niceness 18:45
so maybe people will forgive me that they need insane computing power to run it :o
FROGGS *g* 18:47
tadzik++
tadzik I wonder what would happen if I threw more threads on
18:48 rurban joined
FROGGS you'd have a bigger knot 18:49
tadzik perlcabal.org/syn/S17.html#line_809 18:50
shouldn't that be "Supplies"?
FROGGS: well, not so sure 18:51
there are a lot of things that can be done independently
FROGGS yes, sure
I was just kidding :o)
18:52 rurban left
tadzik I really need to catch up with all that nice threading stuf 18:52
github.com/perl6/roast/blob/master...read.t#L98 is that the easiest way to "run this N things in parallel and wait until they all finish?" 18:53
18:54 darutoko- left
FROGGS no, normally you write 'await' before the loop, and 'start' within the loop 18:55
18:55 jnap joined
FROGGS Thread.start is like something internal that should normally not be used 18:55
tadzik right, hence "lowlevel" probably :) 18:56
FROGGS perhaps you read jnthn.net/papers/2014-nlpw-reactive.pdf
tadzik I didn't immediately find the idiomatic way in neither spec nor tests
FROGGS wait... there were better slides 18:57
raydiak tadzik: checked just FYI, and the laptop is a 1.7 GHz 32-bit Pentium M w/a 533 MHz FSB...so probably a couple notches below most of your target audience :)
FROGGS tadzik: ahh, have you read jnthn++'s latest blög? 6guts.wordpress.com 18:58
tadzik raydiak: well, I'd like my target audience to be as broad as possible
besides, it's a side-scrolling jumping game
18:59 jnap left
tadzik it's a bit embarassing that you need a fluid-cooled quadcore beast to run it smoothly 18:59
FROGGS: I probably did, but I may not remember all of it :) Will look, thansk
ah, that's nice indeed :)
raydiak agreed...I just mean a lot of modern stuff is painful on this thing 19:00
tadzik I can make steroids torment 4 cores instead of one
FROGGS tadzik: there is "the idiom" and also a nice explanation (including a must-know)
tadzik Unhandled exception: When invoking protect, Provided outer frame 0x36e27e0 (MVMStaticFrame protect) does not match expected static frame type 0x36e2540 (MVMStaticFrame ) 19:03
oh nice :)

timotimo aye, perl6 performance can be a frustrating thing :| 19:31
19:31 neuronaut joined
timotimo you can program stuff that's kinda performant in nqp ... but then you get almost no sugar 19:31
lizmat indeed 19:33
oops
tadzik: don't use Thread, use Promises 19:34
or simpler: start { };
which gives a promise
tadzik yeah, I went for start {}s :)
timotimo: well, performance is one thing
but I keep noticing that I keep getting things more or less wrong from place to place 19:35
lizmat is hoping we can tap graphics cards processors transparently in Perl 6 soon
tadzik :o
timotimo i'm also afflicted by an insufficient amount of practice writing actual perl6 code rather than rakudo guts
tadzik for instance, I just tried making physics (velocity) dependent on the actual time that passed since last frame 19:36
and it's all broken
timotimo oh, apologies
tadzik mostly on the user side in this case, not on the framework side
but the fact that I'm making this kind of mistakes makes me thing that there are a lot of hidden bugs in there :)
lizmat tadzik: is there no way that you can use Promises to generate frames async?
tadzik lizmat: not exactly, they all depend on the previous ones 19:37
19:37 molaf_ joined
lizmat is there rendering involved after a frame is done? 19:37
can you offload that to a Promise ?
tadzik yes, but the cost of rendering is infinitesimal compared to actual computation
or so I think :) 19:38
lizmat Benchmark it, I would say :-)
tadzik but the rendering step is basically dropping everything to SDL, which is doing things in roughly 0 time
timotimo well, the rendering is in C, handled by sdl, afaict, and hardware-accelerated
tadzik well, the state changing step is the biggest dealbreaker
lizmat perhaps the dropping can be offloaded?
I mean, Perl 6 *is* doing something to make it so SDL can work with it ? 19:39
tadzik mostly collision detection recently
19:39 BenGoldberg joined
timotimo aren't the things you're giving to sdl CStruct repr'd objects 19:39
?
tadzik they are 19:40
timotimo that means the "dropping to sdl" stuff is spread all over the code
wherever you $my_object.x += 5 it'll "do that
"
:\
19:40 molaf left
tadzik no, no 19:41
the C-repr'd objects basically never change
you query them sometimes though 19:42
timotimo oh
in that case i don't know how things are offloaded onto sdl
tadzik well, the entire rendering is "take @!entities and .draw() them all" 19:43
where draw is "give SDL $!tex, $!x and $!y and tell it to draw it"
19:45 denis_boyun___ joined
lizmat could you do it without gather / take ? 19:45
that's known to be a performance bottleneck, is it not?
timotimo ah, hmm. 19:46
19:46 denis_boyun left
timotimo i think he didn't mean "take" as in "take" 19:47
tadzik no, there's no take
I'll just show you the code
it'll be a pre-release :o

tadzik github.com/tadzik/steroids/blob/ma...te.pm#L103 this is how drawing is done 19:50
should be fairly easy to measure how much time it takes, I'll do that
well, it reaches 10ms if GC comes by, but it's usually 1ms 19:53
19:53 rurban left
tadzik I wonder, if I'll put enough \'s in arguments list, will it never trigger GC? :o 19:54
more generally: what can I do to avoid allocating new objects whenever possible
yeah, I should probably follow setting's footsteps 19:55
I almost never need the containers
...does it sound like it makes any sense?
19:56 jnap joined
lizmat some 19:56
maybe events inner loop could be better as a map ? 19:57
no, that's bogus 19:58
tadzik could it? I don't need the results
I could have a map in animations() maybe
jnthn for uses map...
lizmat also, I wonder whether we could use a better idiom for "@!entities.=grep(* !=== $d);" 19:59
tadzik something like Array.remove 20:00
20:00 jnap left
lizmat perhaps, or maybe just :delete the element you want removed ? 20:01
tadzik ..oh
yeah, that makes sense :)
lizmat or turn @entities into a hash ? 20:02
tadzik wait, is that perl6?
lizmat and just :delete on key
tadzik r: my @a = 1, 2, 3; @a[1]:delete; @a.perl.say

but removing sprites doesn't happen very often, I don't think it's the most costly thing 20:07

tadzik so nqp::bindattr bails out when asked to set a private attr on other class 20:40

aka, shouldn't that just be State ?
tadzik hmm
20:41 molaf_ left
tadzik then it says Undeclared name: State 20:41

20:43 pecastro_ left 20:45 rurban joined
tadzik Steroids::State 20:50
20:50 rurban left
lizmat then, the way I understand things, that's the right class to specify in bindattr 20:51
mayby jnthn can chime in?
jnthn yes, agree it's the right thing. 20:52
Try an nqp::decont($state) as the first arg to nqp::bindattr 20:53
On MoarVM the signature binding lowerer sometimes optimizes away containers when it believes it can get away with it.
But it's "get away wiht it" in the "using Perl 6 syntax" sense, and using nqp:: ops might well expose the difference. 20:54
tadzik heh, the bug is actually with exporting 20:55
(the nativecall one)
I'll try the bindattr in a second
