Anton Antonov @guifa Link(s)? 01:04
guifa Will post as soon as I fixed an issue with the week formatter
guifa is having to do math and ... boo 01:05
01:08 MasterDuke left
guifa Basically I realized that Raku's week-based functions for $datetime were all pretty much based on ISO 01:21
but for proper localization, I needed to be able to adjust the formula. Most of the ones online are optimized for that case, and so I'm working back from a multilayer formula now to see just how slim I can make it 01:22

Anton Antonov @guifa I find programming date both difficult and boring, so, I consider your efforts heroic . 07:35
07:36 nort joined 07:40 nort left 07:43 jpn joined 08:38 sena_kun joined 08:43 Fritz joined 08:47 Fritz is now known as fritz 09:57 holyghost left 09:58 fritz left 10:29 Sgeo left 11:16 lmz left 11:26 jpn left 11:28 squashable6 left 11:29 squashable6 joined 11:56 holyghost joined 12:00 reportable6 left 12:01 reportable6 joined 12:02 reportable6 left, reportable6 joined
guifa AntonAntonov: I don't necessarily find it boring, but difficult for sure. It's so easy to have a single digit or operator wrong and everything blows up. 12:05
I'm still trying to figure out the best way to handle adding in new calendar types 12:11
Timezones was one thing because for the most part it doesn't muck with anything involved in calculations other than the offset which is built into DateTIme anyways 12:12

Xliff Happy Caturday!
.tell tonyo No worries. Thanks for your efforts!
tellable6 Xliff, I'll pass your message to tonyo
Xliff Is this a bug?
Cannot resolve caller openDB(Bizzell::Roles::DB:U: Str:D, Hash:D); none of these signatures matches:

guifa I'd love if we could have Dateish and Timeish objects separate, and then it just happens that DateTime fulfills both roles 13:16

Anton Antonov @guifa Is there an "official" Timish role? 13:28
guifa There is not 13:29
13:29 holyghost left, Xliff left 13:30 Vyrus joined, an3223 left 13:34 Vyrus left 13:35 Fritz left
guifa In a perfect world, we'd have Dateish, Timeish, and then where we have DateTime we could check for Dateish/Timeish 13:38
13:38 jpn left
guifa right now though, the Dateish role is a bit odd, because while you can assume use Dateish as a generic type constraint (allowing other calendar systems), you can't do the same once time is added in 13:40
Anton Antonov @guifa Would it be hard to make perfect parallel world for you? You can define Timish, then, say, TimeDate that inherits DateTime and plays both Timish and Datish. 13:41
guifa Yeah unfortunately it wouldn't serve my goals. 13:44
I'd like to have a drop in module that suddenly makes other calendar systems available but keep them compatible with everything else in Raku 13:45
DateTime::Timezones does that -- just add it and boom, all DateTimes in Raku are now fully timezone aware
Anton Antonov @guifa I see. You need a suitable placeholder role in Datish or DateTime. 13:47
guifa I think it's doable, but I'm not sure how it would interact with DateTime::Timezones. I need to do some more experiments 13:48

guifa The nice thing is once I'm done, the formatting code only requires one tiny change 13:59

gfldex guifa: If you got a standalone time-object (without a date part), how do you convert that to GPS-time (or any other universal time), if you don't know if it's a leap day? 16:13
guifa: Also, how do you validate a time-object if you don't know if a leap second may pop up? 16:14
16:17 jpn left 16:21 jpn joined
guifa gfldex: there wouldn't be a conversion to anything else, as it'd be date agnostic 16:36
Nemokosch leap seconds have been suspended for a long enough time from what I know
from IT point of view, it was super annoying for everyone 16:37
16:44 Fritz joined 16:49 kylese left
guifa New leapseconds have been suspended for the time being -- basically so they can figure out what to do an avoid a Y2K thing when there's a negative one included (fwiw, the ubiquitous tz library already supports them. another reason to not roll your own especially when tz is crazy portable) 16:50
but you still have to deal with the current ones. sort of like if they got rid of DST -- still gotta deal with the older times

Nemokosch the older ones can be just listed. The Rakudo implementation does something to deal with them, even if I'm not completely sure it does "the right thing" 18:20
