| lizmat | what would be required to create a CCLASS_NEWLINE like nqp::const for the 'Canonical_Combining_Class" property ? | 12:17 | |
| so that one could easily see if any characters in a string have that property ? | 12:18 | ||
| nine | Looks like not much. Just adding the new constant, and implementing the test in MVM_string_grapheme_is_cclass | 12:22 | |
| lizmat | hmmm... | 12:40 | |
| actually, that's a property that returns strings, I just realized | 12:41 | ||
| so I'd want to check if it returns "0" | |||
| but that should be easy, no ? | |||
| looking at making Str.raku about 2x as fast | 12:43 | ||
| nine | timotimo: is the profiler's heap analyzer already meant to be used? If yes, you need to push your model additions to p6-app-moarvm-heapanalyzer. | 13:48 | |

| nine | Seems like the plain old moarvm-ha doesn't work anymore either :/ | 14:04 | |
| expected the collectables header at 0xD957A1A6, but got "3\0\0\0" instead. | |||

| samcv | lizmat, yes that would be pretty easy | 16:39 | |
| lizmat, so you are trying to check if a string contains "\n" as fast as possible? why doesn't index work? | 16:41 | ||
| timotimo | nine: sorry, you'll need to grab the heapanalyzer from my github account, or set the moarvm heap snapshot format version number with a define | 16:42 | |
| samcv | ah. you want to check a canonical combining class? which specific property for what reason do you want to check? | ||
| a nqp::index except it works with a propcode and propval would make sense to implement | 16:50 | ||
| nine | timotimo: both format 2 and 3 need changes in p6-app-moarvm-heapanalyzer. | 16:52 | |
| timotimo: is there a special branch? I did look in your github account, but only found commits from 2016 for the heapanalyzer | 16:53 | ||
| timotimo | oh, was i working in a branch? that might be the case | 16:59 | |
| i'm on nqp-ops-makes-stuff-faster at that moment | |||
| sorry about the mess | 17:00 | ||

| lizmat | samcv: the goal was to speed up Str.raku (formerly known as Str.perl) | 18:10 | |
| there's a whole loop for looking up special cases. Which could be evaded if we had a fast way of making sure there are no special cases in a string | |||
| samcv: on second thought: it propably doesn't make any sense anyway, because we need to check for specific exceptions anyway | 18:35 | ||

| samcv | lizmat, the fact uniprop-int does not return 0 for "0" is a bug. not sure how much impact it has on things, though it was on my bucket list | 22:08 | |

| samcv | lizmat, yeah i looked at the code. thanks for making it faster though :) | 23:01 | |
