JustThisGuy Hi all! I have a question about :exists. I have a couple of pared-down examples to illustrate the problem/question. The weird think is that in both cases, the code works in the perl6 REPL. Here is the first: gist.github.com/JustThisGuyAZ/da90...17b9748d22 00:47
s/think/thing/ 00:48
Oh, yeah, here's the version info: This is Rakudo version 2018.06 built on MoarVM version 2018.06 00:49
implementing Perl 6.c.
geekosaur is <y> a typo?
(I think you wanted <$y>)
oh, in fact you didn't an you're hitting a slight gotcha
{$x}{$y} 00:50
<xxx> is shorthand for {'xxx'}
if you want a variable or expression, use the {} form
JustThisGuy Oh, it's treating the $s as string litterals?
geekosaur yes
JustThisGuy Gotcha! Thanks. I bet that's it. I'll give it a try real quick. 00:51
Yep. That was it. Thanks geekosaur! 00:52
The dumb thing is I knew that at one point. I've been away from perl6 for a while. :) 00:53

aqegtfs Voldenet: yeah, that's the ambiguity I mentioned. It thinks you're writing a decimal above, and earlier it thinks you're trying to use an operator. If it could 100% know for sure you tried to detach a non-alpha method, it may as well have it work instead of throw an error. 12:28
12:28 sno left
aqegtfs So the error points to the place where a misparse occurs, not where the detachment happened. 12:28

pmurias .tell Zoffix what I'm a bit concerned with the spec changes proposal is the low point cost of adding an extra method argument 12:52

raschipi I wonder if that process will evolve into something PEP-like really fast, and if it's worthy just going there, instead of getting there in an adhoc manner. 13:00
13:01 Zoffix joined
Zoffix pmurias: I don't really want coredevs to jump through a load of hoops for anything that isn't a bug fix or to treat them as robots incapable of thought where everything must be mandated through policy. Going by memory, an addition of a method argument will require: documentation (or at least an open docs Issue), spectests (or at least minimal feature tests + an open Issue on roast), and a notification to all 13:04
yoleaux 12:52Z <pmurias> Zoffix: what I'm a bit concerned with the spec changes proposal is the low point cost of adding an extra method argument
Zoffix other coredevs about the addition. So that's already plenty of room for anything poorly-designed or controvertial to get noticed before it goes into a release.

Zoffix The above will likely get more than twice faster if you pre-heat JIT

camelia 0.02310777
tyil I've been considering to add an opt to run it a couple times before taking actual measurements 13:26
but I haven't gotten to that yet
Zoffix m: for ^1000 { my @a = ^100; }; for ^10000 { DateTime.now }; { for ^1000 { my @a = ^100; }; say now - ENTER now }
camelia 0.02476375
Zoffix and here possibly GC run to collect those dateitmes makes it a bit slower
m: for ^1000 { my @a = ^100; }; for ^10000 { DateTime.now }; use nqp; nqp::force_gc; { for ^1000 { my @a = ^100; }; say now - ENTER now }
camelia 0.024147748
pmurias Zoffix: I just feel that silently adding some unneeded extra param is a lot more serious threat than a new class being added 13:27
Zoffix Well, the GC thing gets in the way when you're measuring really fast operations
13:27 HaraldJoerg left
Zoffix pmurias: but it's not silently. Notifying all core devs is mandatory. 13:27
13:27 sno left
Zoffix pmurias: also, it's not set in stone. It'll be a trial period after 6.d release to see if the policy accomplishes the desired goals. 13:29
And as I've said, right now it's just a draft, so feel free to tweak it. I didn't even give the points much thought and they're probably an overcomplication all together. 13:30
pmurias Zoffix: I do share your sentiment that they was new stuff sometimes gets just added to the core is not very good 13:32
timotimo Zoffix: did you see when i inspected the @a = ^100 situation last week or so? 13:35
Zoffix timotimo: nope
timotimo iirc it comes down to the push-all method from the iterator that does ^100 being OSR-speshed, which doesn't make the fact available what the type it's called for is 13:36
so every access to the target array (actually, i was using my int @a i believe) was being done through virtual function calls, rather than devirtualized to skip the indirection
Zoffix . <- what you said 13:37
timotimo you'll actually get an even worse situation dependin on how you do it, iirc
Zoffix o <- my head :)
timotimo allow me to rephrase
Zoffix I meant I don't know anything about OSR/spesh/JIT :)
13:38 HaraldJoerg joined
timotimo OK, the effect is, though: 13:38
if it first gets optimized because the inner loop gets run often, i.e. if your range is big enough, it'll create a sub-optimal optimization
if it first gets optimized because the method is called often, you'll get much better code

lizmat well, trying to, bit the current round of optimizations is turning out to be a bit turbulent :-(
El_Che as in breaking stuff? 16:03
lizmat yeah :-(
El_Che you can not have a faster ommelet without breaking some extra eggs :)
are the speed bumps due to a faster moarvm or nqp magic? 16:04

Juerd "the readline situation" sounds rather grave 18:27
Juerd fondly recalls the workarounds he made at github.com/Juerd/shalog/blob/maste.../Prompt.pm 18:29
It was a nice, gentle introduction to NativeCall :)
18:29 desperek joined
geekosaur the readline situation is different platforms have different versions of readline, sometimes in different places, and it's hitting shortcomings of NativeCall with respect to both ABI versions and library path searches 18:29
Juerd geekosaur: Ah, that seems to be what I ran into too, when I tried to augment the Perl 6 Readline with some NativeCall of my own: a version mismatch 18:30
Line 20..38 of the code above was my workaround: simply load all versions and find the one that Readline uses by looking for a string stored in there :) 18:31

Qwerasd The lack of error reporting in threads is very annoying. 21:22
lizmat Qwerasd: could you elaborate ? 21:24
Qwerasd If something in a thread creates an error the thread dies silently. I'm probably doing something wrong, aren't I?
That is to say if a thread dies it doesn't go to stdout. 21:25
lizmat m: await start { die } 21:26
camelia An operation first awaited:

Died with the exception:

lizmat seems to report ok in the simplest case
Qwerasd Non-awaited
lizmat Qwerasd: do you have a gist ?
Qwerasd No, let me get you an example. 21:27
m: start { die }; sleep 2; 21:28

Qwerasd see
lizmat ah, interesting
yeah, that is a bug 21:30
Qwerasd Doy
I thought I must have just been missing something.
21:30 rindolf left
lizmat well, a bit of a gotcha 21:30
the Promise that "start" returns is sunk 21:31
DrForr Juerd: Thanks, looking.
lizmat Qwerasd: it's the checking of the Promise in "await" that throws the error from the thread
Xliff I just created a PR for p6-doc, however when I test it locally, the links don't work.
I have had this happen on more than one page.
Qwerasd I see. Is there any way I could direct that to stdout without blocking? 21:32
Xliff Forward slashes become $SOLIDUS.
lizmat since you never check the Promise, the exception in the thread goes into the wide blue yonder
21:32 subr joined
Xliff m: my $a = start { die "Died"; }; sleep 2; say $a.kept 21:32
camelia Cannot resolve caller kept(Promise: ); none of these signatures match:

Juerd Sunk promises are probably not a good idea but they're in examples everywhere :) 21:33

Zoffix Qwerasd: you can use that ^. When 6.d language is released, Promises in sunk context will report errors automatically 21:36
Qwerasd Thanks! 21:37
Zoffix .tell lizmat the sunk promise throwing errors thing is on the 6.d TODO list: github.com/perl6/6.d-prep/blob/mas...or-handler However, we can't do it by changing behaviour of .sink (can't detect callers lang), so some compile-time thing needs to be done instead. If you wanna volunteer the impl, that'd be great :) 21:38
yoleaux Zoffix: I'll pass your message to lizmat.
lizmat Zoffix: why don't we do that now already ?
yoleaux 21:38Z <Zoffix> lizmat: the sunk promise throwing errors thing is on the 6.d TODO list: github.com/perl6/6.d-prep/blob/mas...or-handler However, we can't do it by changing behaviour of .sink (can't detect callers lang), so some compile-time thing needs to be done instead. If you wanna volunteer the impl, that'd be great :)
Zoffix lizmat: dunno. jnthn is the stakeholder. 21:39
Maybe he just didn't want to have this behaviour in 6.c or maybe there are spectest blocking it
lizmat perhaps, I find my naive approach doesn't cut it, so that might also be a reason 21:40

# good weekly
lizmat ok, the simple fix I tried does not work 21:53
and I'm too tired to think about that now
afk& 21:55
jnthn Zoffix, lizmat: I've pretty much figured it should be done as a language-level transform and for `start` in particular rather than Promise in general. It's really just a case of getting around to implementing it, and making sure it only does that with 6.d semantics. I'll take a look at it once I'm past the current mass of spesh-related work :) 22:00

timotimo vow's method is "keep", not "kept"; kept is a method to create a promise that is already kept 22:13
that's why it only works on Promise:U

camelia 42
timotimo .broken also exists 22:15
