geekosaur you haven't tried to use a C dependency on Windows, have you? (it's not just language; start with just finding the @#$% DLL...) 00:02
00:03 wamba joined 00:04 mcmillhj left, notbenh joined
zengargoyle can you not put C in a DLL and have it in your $?RESOURCES or whatnot? 00:05
geekosaur it necessarily gets renamed, then something like gtk that relies on runtime loading of stuff breaks because the dll has the wrong name 00:07
but, you still have to get the stuff built. (a) windows does not come with a c compiler (b) neither does rakudo (c) if you try to make a user build gtk or readline, they will kill you (d) if you try to build it as part of a module install, you will want to kill yourself 00:08
zengargoyle ah, gotcha. 00:10
00:11 notbenh left
geekosaur and if you download it, you get to hope it didn't change incompatibility (especially fun with gtk3, which doesn't have a stable api or abi unless the gnome devs finally got a clue) 00:11
zengargoyle i haven't tried, but i've thought about just copying some .so i need and pretending i built it like with LibraryMake just making sure the're all loaded. 00:12
00:14 notbenh joined
zengargoyle things like LD_LIBRARY_PATH and LD_PRELOAD usually work for me when some extreme trickery is needed. (but you do sometimes have to set ENV and re-exec yourself. 00:14

ijneb If I have two loops to go through every pixel in a picture 00:43
What's the best way to modify that so that I can go through 10 pixels at a time in parallel
AlexDaniel ijneb: have you tried .hyper or .race? 00:46
MasterDuke ijneb: instead of something like: `for @a { for @b { } }`, you could try `for @a.race(:10batch) { for @b.race(:10batch) { } }`
ijneb I've never used this, I'll play around with it -- thanks guys 00:49

pierre__ Hi all 09:20
i was playing with concurreny, to see the benefit of 6.d and premption on await compared to 6.c
something i do not understand on 6.c 09:21
let's take a simple example
m: my @p; for ^5 -> $i { @p.push( start { await( Promise.in(1) ); } ) }; await @p; say "elapsed {now - BEGIN { now } }"
camelia elapsed 1.0145656
09:21 ChoHag joined
pierre__ that code is running in 1 second more or less 09:21
if i increment the number of promises on 6.d.PREVIEW , everything works perfectly 09:22
however, on 6.c, it seems that when i hit the threadpool size, instead of take them in "slices", it enter in a dead lock
am i missing something?
09:24 lizmat joined

pierre__ Are Promises started with start lazy? 09:28
09:28 wamba left
pierre__ what i'm thinking is that 09:28
timotimo lazy in what way?
pierre__ if i exceed the thread pool in the construction of the array
09:28 Actualeyes left 09:29 lizmat joined
jnthn start just pushes onto the shceduler's queue 09:29
pierre__ the last await will never get called
and hence, the Promises would not be started
09:29 rurban1 joined
jnthn Anyway, the deadlock is because you fill up all of the pool with threads awaiting Promise.in 09:29
And then when the timer fires there's no thread to run the callback on because the pool is full
Thus the hang
timotimo oh, hah
09:29 rurban1 left
pierre__ oh, ok, and with the premptive execution of 6.d 09:30
one of the await will give hand to the callback
09:30 rurban left
jnthn Well, it's more cooperative than preemptive (in that the await is an explicit hand-off point), but yes 09:30
stmuk timotimo: what? I think you always need a national id card (if your country has one) or a passport?

pierre__ what to you mean by quit? 09:35
if by quitting, you mean the client not sending anymore traffic, you will not know if it's "pausing" or quitting 09:36
lookatme close connection
jnthn The Supply you get from the connection will be done
09:36 Cabanossi joined, rurban joined
lookatme I mean the client side call .close on their connection 09:36
jnthn but uh
This code doesn't make sense 09:37
lookatme Hmm? something wrong ?
jnthn Calling .tap inside of a react block is wrong 99% of the time
lookatme oh 09:38
jnthn Unless you really, really know what you're doing and want a totally unrelated pipeline :)
09:38 rumble is now known as grumble
jnthn So the whenever should just go directly in there 09:38

Zoffix Ok, good. I didn't miss anything good :) 11:20
AlexDaniel ok, bad, I just recommended hyper/race to somebody on this channel :( 11:21
my mistake
Zoffix AlexDaniel: there aren't so much "bugs" in them as they were a prototype that snuck in and people were trying to use it. There's new semantics on the drawing board for how these are meant to work and implementing them is still something to be done. 11:22
here: 6guts.wordpress.com/2017/03/16/con...semantics/
hm so they need to be in 6.d 11:23
that moves the timeline further down 11:24
Zoffix rather get 6.d out earlier and ship them in 6.e instead

araraloren I update the Supply example, but seems like it can not working on `base on win10` 12:15
It works fine under my fedora
RockyBalboa Hello! I'm just starting to learn Perl. A quick question about modules. If I have a class "World" defined in file "./Hello/World.pm", I can use this class doing "use Hello::World; World.new;" but is it possible to use directly "Hello::World.new" in my code? 12:17
12:17 labster left
araraloren RockyBalboa, I think you must declare your with `class Hello::World` 12:18
12:19 Cabanossi left 12:21 Cabanossi joined
araraloren The example do something like ssh, free for the suggestion :) 12:21
12:23 lizmat left
Zoffix RockyBalboa: no. You need to load the module to bring in the stuff in it. 12:23
RockyBalboa: or do you mean using 'Hello::World' instead of just 'World'? 12:24
RockyBalboa Thx! Yes I was meaning just using 'Hello::World' instead of just 'Word' :)
Zoffix RockyBalboa: what's inside your World.pm? 12:25
RockyBalboa Do I have to use the "need" keyword or something like that?
I just have: class World { method run() { say "Hello, World!"; } }
I was wondering if I kind do somehow Hello::World.new.run instead of World.new.run (I am trying to convert a Ruby web framework to Perl 6 who dispatches request to Controller.action). 12:27
Zoffix RockyBalboa: you could name it "Hello::World" or put `unit package Hello;` at the top of the file
Some docs (unsure how good they are): docs.perl6.org/language/modules 12:28
RockyBalboa Ok thanks much Zoffix, I will experiment with that. I'm sure it's easy to do that, I'm just not getting used to work with Perl 6 yet

nadim, the same result with clonned repo. I hope you run testing without --force? 12:50

Zoffix: can't use releases, two of the bugs I reported in the last weeks were fixes when I reported them. We'll need to learn to suffer :) 12:52
Zoffix That's just stupid.
raschipi Keep backups offsite. 12:53
Zoffix And I assume you're talking about your DDT module? So no one can use it because it's relying on unreleased release of rakudo.
nadim I think what you should ask is how many people build rakudo because they know things are fixed there rather than a release that can be ages old
RockyBalboa And is it possible to import everything from a module? Something like 'use Hello::*;'? 12:54
sena_kun Zoffix, sure, don't worry.
Zoffix nadim: why should I ask that?

nadim Zoffix: that would tell you something about the users and their willingness to get something with bugs fixed
raschipi Most users will only get Rakudo from their distro.
nadim there are a few hundreds of users world wide, not a million
Zoffix nadim: you're using a complicated piece of software that's not been thoroughly tested and when pointed out that it could destroy your installation you shrug it off and tell me I should be asking how many users are equally reckless. 12:56

Zoffix: People testing them and taking the risk are in part doing us a favor, however. 13:02

But a handful of people doing it who are willing to help triage/report bugs is useful. 13:03

nadim I will but the Rakudo version it works with in the documentation, in clear view. Once it works (it does) and installes on multiple machines , I will run a regression test to find which rakudo release it works on 13:08
So that's a welcome input, better than "stupid", which I may be, and whatever "avoid/garbage" pile 13:09
jast FWIW I thought Zoffix's point was quite clear, and neither did he call you names, nor did he label anything garbage. I see your point, but IMO there was no need to make it personal. 13:14

jdv79 sounds complicated 16:23
16:24 lizmat left, rindolf left
ryu0 Zoffix: you've never used C before? 16:25
jnthn Talking of complicated... MoarVM just learned how to do speculative invocation optimizations. It *will* need tuning yet, but the upshot is (don't generalize from this, please :P) that `for ^10000000 { }` now runs in half the time it used to.
Zoffix \o/
jdv79: well, I need SQLite.pm6 for many other tasks, so it's worth it :)
ryu0: not really. Never had anything good to make with it. 16:26
ryu0 Zoffix: i happened to specialize in C for a number of years. maybe i can assist if you have questions or so.
Zoffix I'm currently reading "C Programming: A Modern Approach" seems a stellar book. 30% through it so far :) 16:27
jdv79 jnthn: cool
ryu0 which standard is it built on?
smls jnthn: Is "invocation optimizations" the same as inlining?
jdv79 Zoffix: don't we have DBIish? 16:28
ryu0 Only ANSI C is more or less fully implemented by all C compilers.
I have yet to see a cross-platform compiler that is fully C99 or C11 compliant.
jnthn smls: It allows further inlining.
Zoffix jdv79: I hate it tho
ryu0 Zoffix: what function(s) does the book recommend for string building? 16:29
jnthn smls: Effectively, when it can't prove what the callee is, but it can see from the stats it's pretty stable, it sticks a guard caluse in.
*clause
And then optimizes as if it knew
Zoffix ryu0: didn't get that far yet. And it covers C88 and C99
*c89
ryu0 Ah. C11 doesn't add much of interest.
16:31 rindolf joined
ryu0 Zoffix: so how did you get into Perl6? i mean, what was your starting resource? 16:31
jdv79 i've only read the c book. didn't find it terribly interesting.
ryu0 ANSI C book? 16:32
smls jnthn: Isn't "can't prove what the callee is" mostly an issue with method calls?
(Wondering why it affects `for ^10000000 { }`...) 16:33
jdv79 i guess. the one by k&r.
jnthn Because the {...} is a closure 16:34
Since for is effectively map
We in theory *could* prove what it is in this case
But closure cloning is relatively high level 16:35
In that we clone the Perl 6 code object and clone the underlying code ref
16:35 Cabanossi left
Zoffix ryu0: annoying people in this channel and working on the compiler :) 16:35
jnthn So we'd need to be able to do fairly sophisticated inter-procedural alias analysis to track that, noting that .clone is a method so we'd already be some speculation deep :) 16:36
16:36 Cabanossi joined 16:37 Guest36538 left
smls jnthn: Or cheat and optimize `for` loops specially... :P 16:37
jnthn smls: NQP does that. For Perl 6 it's more fraught
But cheating would still leave us with a bunch of other places we'd want this kind of opt :)
smls true
jnthn Also, every bit of clever we do in Perl6::Optimizer slows down compilation 16:38
For code that might not even be run much
So when we can avoid games there and get the win out of a more general optimization, it's preferable. :) 16:39

Zoffix It's not a regression tho 18:03
Or maybe it is. 18:04
It's just before that commit, it looks like the $/ was shared around, so it wasn't necesarily "not $0" 18:05

wictory[m] Hi! I'm getting "Could not find symbol &SOMETHING" when I try to access a symbol in an enum 18:32
nadim is the enum defined in the same scope? 18:33
raschipi wictory[m]: Can you golf the error down and then put it in a pastie for us?
wictory[m] The enum is defined inside a class, and I get the tests to run, but when I try to access it from a script outside of the tree it doesn't work
Zoffix wictory[m]: did you export the enum?
nadim then you must export them
Zoffix (if the class is inside the module)
wictory[m] no I haven't
timotimo m: sub ding { enum FooBar <Yoink Bongo> }; say Yoink;
camelia Yoink
nadim or have them at a higher scope
Zoffix wictory[m]: pastebin some code :) 18:34
timotimo m: class ding { enum FooBar <Yoink Bongo> }; say ding::Yoink;
camelia Yoink
timotimo m: class ding { enum FooBar <Yoink Bongo> }; say Yoink;

timotimo oops, that's not how you do that
Zoffix export before values 18:35

timotimo ah but i'll still have to write FooBar in front then?
m: class ding { enum FooBar is export <Yoink Bongo>; }; say FooBar::Yoink;
camelia Could not find symbol '&Yoink'
in block <unit> at <tmp> line 1
timotimo or not?
oh
m: class ding { enum FooBar is export <Yoink Bongo>; }; import ding; say Yoink;
camelia Yoink
timotimo there it is
export alone doesn't mean the outer scope imports it 18:38
just says what gets imported when you do import it
gfldex there are packages all the way down :)

anyway, wictory[m], does that help at all?

wictory[m] I didn't use any < or >, is this wrong? 18:46
raschipi wictory[m]: No, it's fine, they are two ways to write the same thing.
wictory[m] so, should it be "is export"? 18:47
I'm running my out-of-tree script with "perl6 -I~/dir/perl6-openssl test.p6", to override the zef installed OpenSSL module 18:48
18:49 espadrine joined
nadim wictory[m]: either #1 use 'is export' where you define your class and enums + import in your script or # do not use "is export" and use class::Enum to access your enum. 18:51
wictory[m] hmm so if I use "use OpenSSL::RSATools;", it will not work? 18:57

nadim wictory[m]: timotimo showed you the code for both ways, I re-explained them. Try, following timotimo sysntex, it's just 2 tries, if it still fails, nopaste your code as you have been asked above. 19:21

wictory[m] ok everyone :) so the "is export" works (obviously), the problem was that I used "perl6 -I~/dir/perl6-openssl test.p6" instead of "perl6 -I ~/dir/perl6-openssl test.p6" (notice the space) 19:33
thanks everyone for your time!
geekosaur yeh, ~ is actually shell magic and the shell won't translate it unless it's preceded by space (or colon) 19:34
