tonyo m: say S:g/ $<a> = <:Lu> || $<b> = <:!Lu> /{$<a>??$/.lc!!$/.uc}/ given "AbCd" 00:09
camelia aBcD
tonyo there ya go 00:10
codesections :-) so much better
guifa Actually if yyou're doing that, there's no reason to check for <:!Lu>, you can just do $<b> = . 00:14
m: say S:g/ $<a> = <:Lu> || $<b> = . /{$<a>??$/.lc!!$/.uc}/ given "AbCd" 00:15
camelia aBcD
guifa m: say S:g/<:L>/{$/ eq $/.lc??$/.uc!!$/.lc}/ given "AbCd" 00:16

guifa Golfing further (at the cost of perf) 00:19
m: say S:g/./{$/eq$/.lc??$/.uc!!$/.lc}/ given "AbCd" 00:20
camelia aBcD
guifa points out that after codesections 's last reddit post, he's not allowed to complain about line noise in the last time 00:21
moon-child one char longer, infinitely classier:
m: say S:g/./{[&lc,&uc][$/eq$/.lc]($/)}/ given "AbCd" 00:22
camelia aBcD
guifa ^_^
codesections Agreed
00:26 sono joined, _ed joined
guifa Also, I think I finished up Dateish.fmt … I think the formatters' code isn't too ugly 00:30
Thoughts? github.com/alabamenhu/DateTimeFmt/...imeFmt.pm6

moon-child probably the api should be redesigned to take an array of lines for 'expected' and call .lines on the result of the function 01:02

01:42 _ed joined 01:46 _ed left 01:50 _ed joined 01:55 _ed left
rassoc noob question regarding that code: why bother with nqp::if when the regular if would be more readable? perf seems to be the same, according to this answer: stackoverflow.com/questions/551072...8#55107548 01:56
02:00 _ed joined 02:03 lucerne left, lucerne joined 02:04 _ed left
codesections Wait, I think I'm missing something, rassoc. What in that answer tells us that there's no perf difference? 02:08
rassoc wouldn't perf be listed under notable differences if it was significant? 02:10
02:12 _ed joined
codesections Hmm, I'm not sure. That seems like some evidence, but not 100%. In particular, I thought that some (all?) of the perf cost of an `if` came from building a new lexical scope, which is the second bullet 02:16
(the perf cost of it versus other conditionals, I mean – obviously branching code is going to lead to branch prediction misses/less optimized code in general, but that goes for any branching/condititioal) 02:17
02:24 _ed left
rassoc well, what the heck do i know. all my raku stuff runs like arse, not yet qualified to contribute on that front ;) 02:25
codesections well, don't take my word for it, that's for sure! 02:26

moon-child I want to pass a Buf into a nativecall function. Is there a way to do that? 03:17
looks like nativecast(Pointer) will do it 03:18

tonyo what is your Buf of? 05:13
Buf[uint8] ?
moon-child yeah 05:14
tonyo you likely just want to pass uint8[] and the size 05:15
whatever func(unsigned int xs[], int xl) 05:16
or whatever your actual compiler type is func(uint8_t xs[] ..) 05:17
moon-child no, it's a string
Str on raku side, buffer (not nul-terminated) on c side
tonyo buffer of unsigned chars, then? 05:18
or wide chars?
moon-child regular size chars
nativecast(Pointer) seems to do the job 05:19
tonyo oh, those fools. you can cast pointer but you'll still want the length
unless it's always fixed
moon-child well, yeah, but that's easy
tonyo not if you can't count 05:20

guifa oof 05:49
I did something that's slowing down my dateish.fmt code. Suddenly got to be an order of magnitude slower =\
05:51 _ed joined 05:55 _ed left 05:58 Doc_Holliwood joined
guifa But … I'm a good 50% faster than sprintf generating a similar string, so I guess it's not terrible then given I'm handling all the same padding features. 05:59
moon-child maybe you should submit a patch to improve sprintf's performance! 06:01
06:02 reportable6 left 06:04 reportable6 joined
guifa moon-child: there's probably a little bit more going on under the hood with sprintf 06:07
but lizmat has been working on optimizing sprintf via caching the formatters, I don't think that's in the master branch just yet
06:09 _ed joined
guifa I'll do the same to my code once that's done and given that doing .&{ .year ~ '-' ~ .month ~ '-' .day } is currently about 30x faster than .fmt('%Y-%m%d') and about 60x faster than sprintf('%d-%d-%d', $date.year, $date.month, $date.day), I'd imagine the cached method will bear some pretty substantially improvements 06:10
s/once that's done/once RakuAST is done

moritz you never told raku that you want to match a full string 14:53
so it searches for a substring

moritz but if you just want to check a number, no need to go for a regex
