timotimo thank you, raydiak 01:12
we kind of sort of have these pod blocks 01:20
they are super hard to input properly on the channel, though :)
01:24 zcm joined 01:31 rurban joined
raydiak is CArray of structs still NYI? 01:35
timotimo no
it is implemented 01:36
don't forget to .new the CArray! :P
raydiak yes I got past all that and some other stuff too
timotimo :) 01:37
raydiak still no dice, even with proper error checking
timotimo may i see?
01:37 larion left
raydiak yeah just a minute, I'll gist 01:37
timotimo did you use "int" when you meant "int32"? :) 01:39
raydiak pressed 'u' a bunch of times in vim to get back to the supposedly-almost-working point :)
timotimo haha
excellent
do you know extensions like undotree and such?
raydiak yes I've played with them, but...I keep my vim config very simple...should be using some plugins I'm sure 01:40
where is the int32 supposed to go? I used 'int' where the SDL docs did...is that bad? 01:41
timotimo yes, it is
in C, "int" is 32bit
in perl6, int is 64bit
raydiak heh okay, one more global replace, then I'll gist if it's still broken :) 01:42
timotimo what are you making? 01:43
raydiak I was just playing with what he started, seeing what the problems were...and it gives me...ideas... 01:44
timotimo k 01:45
raydiak here is where it's at now: gist.github.com/raydiak/9193e818d781a80ad946
raydiak hopes he pressed 'u' the correct number of times 01:47
timotimo and you don't get an "invalid renderer" any more?
i don't know why grondilu and you chose these flags for window and renderer
raydiak nope, just blackness again
timotimo i'd at least set "accelerated" and "opengl"
raydiak idk why he chose them either, suppose I can play with those next 01:48
timotimo also, i suggest you cargo cult a few bits from SDL2::Raw
in the examples, see how i used "SDL_CreateRendererAndWindow"
which should give you a better chance at getting a valid renderer
raydiak well, I'm sure just *using* SDL2::Raw would solve a lot...I pretty much nerd-sniped myself into trying to figure out specifically what is wrong here though 01:49
timotimo yeah, me too ... kind of
but then i had a person who was interested in perl6 and i talked to him a lot
flooded him with stuff, i suppose
poor guy
raydiak there is a lot to say about it, that's for sure 01:50

raydiak oh right speaking of time-wasting...you have no idea how furiously I was banging on my keyboard before I found out the snake doesn't die when it hits something :) 01:54

timotimo (not quite sure why it's nomming so many datas)
that code seems to allocate a crapton of Int objects. perhaps our for-to-while optimization is b0rked yet again 04:11

hello
moritz \o pmurias
FROGGS_ perl6_newbee: can you make it slurpy instead?
perl6_newbee slurpy?
for each str a parameter on its own? 13:11
psch a named array parameter needs multiple instances of the cl-argument it seems 13:12
i.e. "perl6 test.pl6 --tags='foo' --tags='bar'" works for me 13:13
moritz that's a bug; a single one should work
psch but only one --tags doesn't
perl6_newbee aah psch is right. several --tags parameter and the script works 13:14
dalek c: cb7856f | moritz++ | htmlify.p6:
htmlify: document the build process in the comments

perl6_newbee until it is fixed I will use Str and split it at the ',' char. thx for the help
psch ooc, is that designed? i.e. should "--tags=foo,bar,baz" select an :@tags candidate and split on ','` 13:16
?
perl6_newbee that would be very convenient. by the way I thought it works this way 13:17
psch it seems a bit too magic to me on first impression 13:18
vendethiel yeah. maybe --tags=a --tags=b would make more sense
perl6_newbee I am a lazy person, even when enter command line parameter... 13:19

psch that's why one --tags doesn't dispatch to the :@tags candidate 13:29
which i suppose is correct, but makes the MAIN stuff kinda complicated
(note the second .cando doesn't find &f)
moritz there's extra argument massaging for MAIN
it needs to take that into account
psch moritz: yeah, the extra argument massaging has to assume every named could be an array as i see it 13:30
we don't get an implicit *@_ though i think, which makes that kinda ok, maybe :/

perl6_newbee hmm maybe my question is lost. once more:
I have a script with a sub MAIN(several parameters) at the top. Always the usage is shown if I call it without parameters 15:50
I have add a line code just before the MAIN declaration. my $sql = SqlWrapper.new(some paramters); And now the usage is no longer printed. Is that a bug? 15:51
moritz perl6_newbee: I'd have to read it up in S06 myself, but I'd tend to think it's a bug 15:53
perl6_newbee thx
its enough to declare a variable just like "my $sql;". Still no usage. 15:55

psch moritz: yeah, i'm having trouble identifying behaviors that seems correct, seeing as S06 doesn't talk about array params at all 16:06

perl6_newbee ok, where can I file a bug report? 16:09

[ptc] for instance, I'm trying to rename throws_like() to throws-like() and simply pass the arguments from one to the other

vendethiel m: sub foo(*%a) { say %a.perl; }; sub bar(*%a) { foo(|%a); }; bar():a;

vendethiel here.
[Coke] [ptc]: perl6-roast-data is run on a linux box. all the rakudo implementations are run. niecza and pugs don't build on that the latest box we were running them on, so they are not enabled currently. Even if they were, we'd deal with it. 17:30
[ptc] then I can rename it to throws-like($code, $ex_type, $reason?, *%matcher) and have throws_like() pass with |%c?
TimToady m: sub foo(*%a) { say %a.perl; }; sub bar(|c) { foo(|c); }; bar():a; 17:31

[Coke] 234% - because the meaning of the percentages chagned at one point, I think. used to be rakudo-parrot was the key value. then it was changed so that "the most" was the key value (er, key==100%). The percentages are all relative for teh given day of the run, they don't mean anything in particular.

lizmat timotimo: so there *is* a difference between using nqp::opts l)ike isge_n) when using native nums versus using >= ? 17:42
is this also true for ints ?
moritz lizmat: I guess even the inlined sub has a non-zero cost 17:43
lizmat timotimo: wrt to boxing a Num, could that be the num -> Bool conversion, ?
moritz like the guard clauses that check the types
lizmat: I'm pretty sure nqp::p6bool does not box a Num 17:44
dalek rl6-roast-data: bfc2b36 | coke++ | / (3 files):
rakudo.parrot is not currently an option;

TimToady is currently trying using all 64 bits returned from rand_i before calling it again, but it's not clear whether that will be faster 18:50
timotimo you know Bool.pick only has to return either True, False, (True, False) or (False, True)? :) 18:54
18:54 BenGoldberg left 18:55 BenGoldberg joined
timotimo (i'm expecting you've really been talking about roll) (or maybe you're caching one 64bit integer result?) 18:56
TimToady I'm testing on pick, but plan to work on roll if I can make pick faster 18:57
well, I know I can make it a little faster by using rand_i and comparing with 0, but I'm gunning for more 18:58
yes, I'm caching 64 bits at a time, but the nqp ops to get bits out run about the same speed as MT does so far 19:02
in principle they should run faster, so maybe it's worth it to have code in there that may be further optimized later 19:03
19:04 lucas__ joined 19:06 mvuets left
TimToady well, crud, suddenly the old code is now faster, so now there's no measurable difference with the floaters, so I'll just forget it for now 19:09
but you'd think that multiply floaters just to pull single bit out is suboptimal 19:10

Kristien are there multidimensional arrays like in c#?
or should you create arrays of arrays?
TimToady how should I know?
Kristien you know a lot about Perl 6 :P
TimToady knows next to nothing about C# though 19:11
Kristien oh right
you can create arrays with arbitrary dimensions, like int[,] for a 2D array which can be indexed as [1, 2]. this is guaranteed to be rectangular unlike arrays of arrays 19:12
19:12 bronco_creek joined, rurban left 19:13 Mouq joined
bronco_creek o/ p6 19:13
TimToady well, to create a concrete array in P6 it'll be my int @array[3,4], but there's not yet any plan for a type representing only rectangular arrays 19:17
as currently defined you could constrain a paramater @array where *.shape[*-1] ~~ Int or so
*meter
Kristien ok :p 19:18
TimToady I suppose one could define a role that enforced that typology
but my int @array[*,*] is potentially ragged
19:19 _mg_ left
TimToady er, *;* rather 19:19
likewise 3;4 above 19:20
my int @array[1,2;3,4] wold, in theory, be an array with 1 or 2 entries in the first dimension, and 3 or 4 in the second 19:21
but it might be more important to catch the , vs ; error, or require a ; somewhere if you really mean something like that
it's not needed really for arrays, but hashes want to be able to define the sets of legal keys 19:22
my %hash{DaysOfWeek; HoursOfDay} 19:23
so enums or sets or lists would define sets of valid keys
in that dimension
(though by that set-of-keys reckoning, [1,2] is illegal, since arrays are always 0 based 19:24
19:24 grondilu left
TimToady but nothing says we have to interpet lists the same for array indices as we do for hash indices 19:25
except maybe a hobgoblin or two
so interpreting each of them as a valid size rather than a valid key seems okayish to me 19:26
19:26 Rounin joined
TimToady if we want to get that fancy, which we probably don't, at least not for 6.0 19:27
but we should reserve the syntax, so [1,2] is illegal if you really mean [1;2]

grondilu ok but C's sizeof is so famous it might be a good thing to keep it as is. Possibly just make an alias or something. 22:27
plus it's not like it's going to conflict with an other name in rakudo.
22:27 jack_rabbit_ joined
grondilu though more elegant would be a size method to all native types. 22:29
(not sure it's possible thouhg)
FROGGS_ grondilu: that's not so easy, because NativeCall usually just offers a representation
grondilu yeah I was beginning to realise it's not that simple. 22:30

grondilu (yeah, makes sense)
I still think an exact equivalent (including the name) of C's sizeof would be nice. 22:33
FROGGS_ but yeah, I'd like to call it 'sizeof' too, but I'd wait for jnthn++'s opinion here :o)

grondilu wonders why rosettacode.org/wiki/Image_noise#Perl_6 does not catch Interrupt (Ctrl-C) signals. 22:41
Mouq FROGGS_: Shouldn't nativecast and nativesizeof be consistent with refresh? So they can be called as NativeCall::sizeof or use NativeCall :utils; sizeof
grondilu (jeez now I can't kill it at all) 22:42
psch FROGGS_: i don't if PR 370 is sufficient. from my POV, array parameters to MAIN are somewhat underdesigned
FROGGS_ Mouq: you cannot call NativeCall::refresh though... but I see what you mean 22:43
Mouq Oh.. I guess not :P
psch FROGGS_: i.e. moritz++ suggested to require typing a Scalar parameter as Str if you don't want to allow listyness for that parameter, but what happens with «multi MAIN(:$foo) { }; multi MAIN(:@foo) { }» in that case..?
grondilu eventually killed it. Whishes he knew what's wrong with this program.
FROGGS_ psch: I just want to know if you spectested it, because at least when I asked I was unable to test it 22:44
masak quick question: what does it mean for `?? !!` to associate to the right? what does `A ?? B !! C ?? D !! E` parenthesize to? `A ?? B !! (C ?? D !! E)`, right? does that mean that C can be considered the rhs of `A ?? B !! C`?
psch FROGGS_: oh. yeah, i had spectested it, but the behavior is definitely up for discussion imo
FROGGS_ multi MAIN(:$foo) { }; multi MAIN(:@foo) { } is ambiguous for one element
okay
so I wont merge it? 22:45
Mouq masak: I'm pretty sure that's how the grammars do it
psch i had a passing todo and a fail somewhere in S17, which i think are known flappers
FROGGS_ psch: probably
masak Mouq: could a left-associative `?? !!` operator exist? how would it parenthesize?
Mouq: is A the lhs? what does that make B?
psch «multi MAIN(:$foo) { }; multi MAIN(:@foo) { }» in PR 370 would dispatch to the first candidate with one argument, fwiw
currently it always dispatches to the first, no matter how many arguments 22:46
grondilu (a ?? b !! c) ?? d !! e would makes some sense and would qualify as the left associative version.
masak indeed. 22:47
so ?? !! has an lhs (A), a *mumble* (B), and an rhs (C).
Mouq masak: github.com/perl6/std/blob/master/STD.pm6#L3902 B is parsed with the operator, and handled by later as a special case

masak Mouq: I know. I'm trying to think up multi-part user infixes for 007. 22:48
lizmat ok, I have a bit of a dilemma: 22:49
I have a patch that will make substr-rw accept all the parameters that substr accepts
(it currently doesn't)
grondilu timotimo: FYI, switching to Bool.pick allowed to go from about .07 fps to 0.8 fps. It's clearly not the bottleneck here.
lizmat the con: it makes substr() about 2.5x as slow
Mouq .o( circuminfix:<?? !!> ) 22:50
grondilu oops, I meant 0.08 fps instead of 0.8
FROGGS_ lizmat: btw: gist.github.com/FROGGS/75dc69c6939956d16f73
lizmat the gist of the substr(-rw) patch: gist.github.com/lizmat/695c8187f5279ab41c88
FROGGS_: huh, I've built and spectested on jvm earlier today 22:51
lemme pull and check again
didn't we pull some Test.pm stuff earlier today ? 22:52
FROGGS_ that too, yes
and there was something about substr taking whatever code as second argument
lizmat yes, but that only complains now if there is an actual error 22:53
and which I will fix tomorrow anyway
FROGGS_ I am just too tired right now too look at any code 22:54
