| 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 | ||

| 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 | ||

| 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 | |

| 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 | |

| 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 | ||

| 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 | |

| 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 | 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 | |

|
|||
| 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 | |||
