Herby_ o/ 00:07
question. If I have two strings "12/31/2015 0400" and "12/31/2015 0700", how do I convert those to datetime objects to see if greater there is greater than 4 hour difference between the two? 00:08
I have a tenuous grasp on datetime in general, and I can't figure it out in the docs 00:09
00:12 konsolebox left
jnthn I don't think anything built-in will parse that format (it'll only do ISO 8601, and that sure ain't what you have) 00:12
00:13 konsolebox joined
Herby_ hmm. any recommended modules to use? 00:14
jnthn m: given "12/31/2015 0400" ~~ /(\d+)'/'(\d+)'/'(\d+) ' ' (\d\d)(\d\d)/ { dd DateTime.new(day => $0, month => $1, year => $2, hour => $3, minute => $4) }
camelia Month out of range. Is: 31, should be in 1..12
in block <unit> at <tmp> line 1
jnthn Middle endian be dammed!
Herby_ :) 00:15
jnthn m: given "12/31/2015 0400" ~~ /(\d+)'/'(\d+)'/'(\d+) ' ' (\d\d)(\d\d)/ { dd DateTime.new(month => $0, day => $1, year => $2, hour => $3, minute => $4) }
camelia DateTime.new(2015,12,31,4,0,0)
jnthn That's one way to parse it
Then I think you can just use - with the two to get an Instance
uh, Instant
Herby_ great, i'll give that a go. Thanks!

Herby_ Zoffix: I'm following along your Weatherapp tutorial. Did you ever write any code for part 4? 01:13
SmokeMachine the way I think, abc contains the letter (True) in 3 possibilities of 'a'..'f' (a, b and c) and doesn't contains in another 3 (False) (d, e and f)... so, in my mind, the answer should be: {False => [abc abc abc xyz xyz xyz xyz xyz xyz], True => [abc abc abc]}
could, please, someone explain me that? 01:14

SmokeMachine This code was gotten from a roast test... 01:25
raschipi what does the test say the result should be? 01:27
and are you sure the test isn't fudged for rakudo?
SmokeMachine github.com/perl6/roast/blob/ac5295...ify.t#L126
timotimo it occurs to me that .classify({ $_ }) is equivalent to .Bag 01:28
well, you might have to put an xx in there as well 01:29
raschipi RT #126032
synopsebot RT#126032 [resolved]: rt.perl.org/Ticket/Display.html?id=126032 The .classify method is calling the closure twice on the first element
raschipi Right, it's expected. Not supposed to be used in that form, it's just for the test. 01:30
m: say so <abc>.contains: any 'a'..'f' 01:31
camelia True
raschipi m: say so <xyz>.contains: any 'a'..'f'
camelia False
raschipi m: say so <abc>.contains: all 'a'..'f' 01:32
camelia False
raschipi m: say so <abc>.contains: all 'a'..'c'
camelia True
SmokeMachine But, shouldn’t it return {False => [abc abc abc xyz xyz xyz xyz xyz xyz], True => [abc abc abc]}? 01:33
I still don’t get it... 01:35

01:37 Todd joined
SmokeMachine raschipi: what’s the value of a test that uses a form that shouldn’t be used? 01:38
Todd Hi All. I am about to write a Perl6 program for a customer on Windows 7, sp1, 32 bit (not 64)
01:39 xi- left
Todd Is this the best place to download Perl 6 for Windows 32 bit? rakudo.org/how-to-get-rakudo/ 01:39
01:40 BrianOn99 joined
Zoffix Todd: in a way; you'll notice the 32-bit version is nearly 2 years old 01:40
Todd nuts, any better download?
raschipi SmokeMachine: It's not that it shouldn't be used, it's just that it doesn't collapse a junction before using it and junctionsare more useful when they collapse.
Zoffix Todd: you could try building from source: github.com/zoffixznet/r#windows 01:41
Todd: note that JIT is not available on 32-bits, so your rakudo will be noticably slower 01:42
Todd: may want to run `git checkout 2017.11` before the `perl Configure.pl` step to get a much more well-tested the release commit, rather than bleeding edge
01:43 xi- joined
Todd If I build, it look like I will need Perl 5. Was hoping not to have to do that. Also, speed is not an issue. Works properly is. 01:43
Zoffix Todd: yeah, Configure.pl is a Perl 5 script; also you'll need a C compiler, which comes with Strawberry Perl 5
Todd rats. I was hoping for a lot easier 01:44
01:44 BrianOn99 left
Zoffix Sorry. No volunteer stepped up with the resources to build 32-bit Windows 01:44
Todd looking at the link, I do not see a switch for 32 bit. My Windows VM is 64 bit. I would like to compile it locally 01:45
Zoffix It figures it out automatically. No idea if there's a switch to force it into 32 bit 01:46
Todd poop
if I originally write it in Linux, do I need to be careful to use an editor that saves in cr/lf 01:48
?
Zoffix Todd: write what? 01:49
lookatme No, if you execute it with `perl6 xxx.p6`
Todd my perl6 program. get a head start on it in Linux (my base system). then remote into the customer's w7 machine and copy it over and finish it off 01:50
lookatme The newline only effect shebang, I think
Zoffix Todd: it'll work, but depending on what you open it with on Windows, it might end up all on one line (e.g. in notepad.exe). Just run `unix2dos foo.p6` before sending it
Todd forgot about that one. thank y for hte reminder 01:51
I think I will try to old versionof rakudo. If it doesn't work, then I will try compiling up a new one. Thank you guys! 01:52

anop: degree is basically the number of threads
anop: and batch is how meach each thread “takes” each time 08:00
perhaps my explanation is not clear enough :)

lookatme Not sure, it's no document about it. Only batch is clear
AlexDaniel well, each thread will take 32 items, process them, then take the next 32 and so on

is right ?
is it right ?
lookatme According the mean of `degree` :) 09:13
AlexDaniel anop: well. If you have 4 threads, then three of them will be processing 32 items, and the fourth thread will be processing just 4 items…
lookatme :) byebye
09:13 lookatme left
AlexDaniel so ideally you should set the batch size to 25 if you have 100 items exactly 09:14
but I'd go lower than that assuming that the processing may different time… 09:15

jnthn wander: The should always be an unambiguous first thing to dispatch to. Re-dispatch works by calculating all of the possible targets, then excluding the first one, and then iterating through those. 10:37
wander aha, that's it. 10:38
thank you.
El_Che hey jnthn, coming to next fosdem? 10:39
DrForr I would ask the same of you :)
(if I haven't already.)
El_Che hehe 10:40
jnthn wander: I mean, conceptually nextsame works by iterating a candidate list calculated at the point of the original dispatchy
wander: But if we implemented it like that then performance would be pretty terrible 10:41
So we cheat and hope to not get caught. ;)
I think the refusal to dispatch to an unambiguous first candidate makes that safe.
Since we know that calculating the list upon first use of nextsame using the original arguments, then dropping the first result, means that the result we drop matches the one we'd originally hit 10:42

This Seq has already been iterated, and its values consumed
(you might solve this by adding .cache on usages of the Seq, or
by assigning the Seq into an array)

jnthn I guess in that case we build the DAG in such a way that it happens to toposort (in this case at least) such that the nextsame visits the things in source order. 13:40
HoboWithAShotgun timotimo: interesting 13:41
jnthn But nextsame is about iterating all possible candidates
wander as to multi dispatch, we choose *one* candidate, so there is no DAG built? 13:42
jnthn There's always a DAG built
That's how we decide the order to consider candidates in the first place
13:42 konsolebox joined
jnthn Just saying that it's pure luck that you get 012 and not 021 13:42
wander there should be, all that confuse me is the inconsistent
jnthn Oh, actually...maybe not
I guess it has to preserve that order for tie-breaking where clauses 13:43
Well, I guess we could change it so nextsame and friends also blow up with ambiguity errors 13:44
But I'm not sure if that's helpful :)
13:44 mson joined
jnthn But overall, I'm not sure one should expect two different things to be consistent 13:48
When you want to call one thing, there must be an unambiguous result. When you are iterating things, as next* does, then it's not an issue if there's multiple things that could be visited.
13:50 philomath joined 13:52 cdg joined
wander even if in which order we iterate thing is unclear? it looks like we iterate these candidates by the order same as how we choose the first one. and now it tells me for some candidates, the order is random 13:53
we define some tie-breaker and then define textual ordering as tie-breaker's tie-breaker 13:54
why not textual ordering itself be a tie-breaker 13:55
HoboWithAShotgun an explicit call and one via nextsame may be different things, but i'd expect this to blow 13:58
jnthn Because ambiguous dispatches on type are very rarely what anyone intended
[Coke] japhb++
HoboWithAShotgun that's the point, it's rarely intended and ambigious and it should at least produce a warning 13:59
jnthn Then write a patch to make nextcall explode in that case, and we can see what the impact is. 14:00

DrForr You're declaring $espace_r each time through the loop. Try declaring it before the loop. 14:19
Alternatively you could use 'state $espace_r = 0;' and it'll get initialized once, then used every subsequent time. 14:20
And you're initializing it to a number, and concatenating a string.
14:23 philomath_ joined
wander as our tie-breakers of PEGs, textual ordering always works. it looks like we believe when users deal with PEGs, they know what happens(textual ordering matters). 14:23
then for the very case of multi dispatch, we assume when users define 'ambiguous' candidates, that is a mistake.
and when they use tie-breaker explicitly, we trust them again, saying they know textual ordering matters. 14:24
DrForr Also, you want ~= in order to concatenate *to* something, just using '~' will return the concatenated string, not store it.
14:24 philomath left
