patrickb Hi! 09:37
I'm currently failing running a program with Proc::Async with a space in it's path and arguments on Windows. 09:38
Is there a known bug?
jmerelo patrickb: not that I know of. But maybe you need to escape the space 09:40
patrickb Another datapoint: The program needs to be a bat file.
I start to suspect Proc::Async is actually calling the program correctly, but cmd is confused because it tries to read the program name and stops at the space 09:41

lucasb To make a user-defined object participate in iteration constructs, all you need to do is either define a .list or a .iterator method. No need to do any specific role. 21:29
do you agree with my statement? was it supposed to be that easy to iterate over objects? :) Because I think 'list' is a very common name. Other special methods are all UPPERCASE 21:30
ugexe Subclasses of Any may choose to return any core type that does the Positional role from .list. Use .List to coerce specifically to List. 21:35
TreyHarris Well, Any defines .list, so I think... yes, what ugexe said
I think you can consider any routine defined on Mu, Any, or Cool as effectively quasi-reserved ("quasi-" because if you know it exists and what you're doing you can use it for your own purposes) 21:37

TreyHarris The final example in docs.perl6.org/language/operators#infix_minmax showing minmax on a Hash... it's fine as far as it goes in showing what minmax returns, but I can't figure out how one could ever use the Range that results. I thought I'd augment the xample, but I've gotten stuck trying to make a minmax on Hashes return a useful Range 21:43
cpan-p6 New module released to CPAN! FindBin (0.2.0) by 03LEMBARK 21:44

lucasb ugexe, TreyHarris: thanks for the comments. I'll try reflect more about this :)
ugexe FindBin functionality (or anything you'd do with it) is built-in already
21:47 patrickb left, reach_satori left
TreyHarris ugexe: What's the built-in? 21:48

TreyHarris In Perl 6, $*EXECUTABLE is an IO object so it's arguably (nearly) as easy as FindBin, but in Perl 5, finding your script's location in a platform-independent way isn't trivial 22:12
22:14 reach_satori joined
TreyHarris I meant $*PROGRAM, but checking it I see it isn't the same as FindBin... it doesn't follow symlinks to find the canonical location of the actual program file 22:15
I haven't looked at this just-uploaded FindBin's code -- it's not in my mirror and it isn't a public repo in lembark's GitHub -- but assuming it does what Perl 5's does, you'd have to replicate the same logic (check in a platform-dependent way for the actual file's canonical location even if it's called by unusual means like a three-arg *exec call or something like that) 22:17

RaycatWhoDat I was wondering if anyone has deployed Perl 6 to production. If so, what did you use it for and what were the downsides? 22:43
timotimo i forgot the name of it, but there's a thing for agriculture that runs on perl6 22:44
agrammon?
www.agrammon.ch/home-en/ 22:45
but i didn't deploy that so i can't answer that particular question
RaycatWhoDat Fair enough. Thanks for the link, though. 22:46
timotimo there was also a presentation about agrammon, i think the recording is on line, on youtube probably. i think it was presented at a german perl workshop perhaps? 22:47
El_Che I ran a service to assist with a CA SSL cert migration for a few thousands certs (around 3000 iirc). It checked the CA of webservers and other services and send notifications about the need to renew the cert with the new system (new CA). 22:49
it ran for about 2 years
the migration is done, so the service is gone
22:50 SergiusUA left
RaycatWhoDat Did you choose Perl 6 because it was what you knew? Or did you seek it out? Like, why Perl over the hundreds of languages out there? 22:51
El_Che I chose Perl 6 because I wanted to learn the language in a real life scenario 22:52
kawaii am I not allowed to call routines as the values in my hashes? `my %ivs = hp => (0..31).rand.Int,` gives me an error of unexpected `(`.
El_Che I did know Perl 5, Java and Go
timotimo m: my %ivs = hp => (0..31).rand.Int, "hi"; 22:53
camelia Odd number of elements found where hash initializer expected:
Found 3 (implicit) elements:
Last element seen: "hi"
in block <unit> at <tmp> line 1
timotimo m: my %ivs = hp => (0..31).rand.Int;
camelia ( no output )
timotimo it should work; the error might actually be nearby?
RaycatWhoDat El_Che: Interesting. Did you run into any problems?
El_Che RaycatWhoDat: no, it ran well (of course the scope was limited)
no crashes
no perfomance problems 22:54
RaycatWhoDat Huh. Neat. Thanks for your insight.

vrurg What would be the best way to test for a warning message? The first thing coming to mind is CONTROL { when CX::Warn { die $_ } } 23:28
TreyHarris vrurg: Test should probably have a warns-like... warn is pretty seldom-used though, given that its uses in Perl 5 are mostly subsumed by note() and by Failure 23:31
For coverage purposes, though, you're right that it should be testable. The CONTROL block works, though I'm not sure throwing it is the best way, since presumably you'd want execution to continue, wouldn't you? 23:32
vrurg TreyHarris: warns-like isn't documented. So, even if it exists.
23:32 MasterDuke joined
TreyHarris vrurg: It doesn't; that's why I should "should probably have", a la fails-like 23:33
23:33 MasterDuke left, MasterDuke joined
vrurg It's been tested with throws-like anyway. So, rethrow of control is ok 23:33
TreyHarris Oh! I thought calling die() on a warning turned it into a full-blown exception
vrurg It does. Basically, what happens (schematically): 23:34
TreyHarris I thought rethrow would be what would be needed in that case
vrurg { CONTROL { when CX::Warn { die $_ } }; throws-like { warn "ok" }, CX::Warn; }
Rethrow should preserve the original exception status, I presume. Even if it's not this way right now – it must be, to my view. 23:35
TreyHarris ah, I see, you're throwing and then re-suppressing it all at once. Your elided example made me think you were promoting the warning and interrupting execution
vrurg Damn laziness... Shoud've made it in full from the start. :) 23:36
