nevada1 Hey, is there any truth to some kind of unified language iteration called Perl 11? Or is that some kind of running joke. 01:17

hythm how to execute one of two operations randomly? like ( $a + $b ) or ($a - $b ) ? 03:15

evalable6 0
masak hythm: maybe like that?
works unless you're planning to expand beyond two operators later, I guess 04:35
or, if you prefer `if`: 04:36
m: say do if Bool.roll { 1 + 1 } else { 1 - 1 }
evalable6 2
masak (though `?? !!` reads better to my eyes than `do if`)
04:36 eythian left
masak oh, parens work too: 04:36
m: say (if Bool.roll { 1 + 1 } else { 1 - 1 })
evalable6 0 04:37
hythm That works, Thanks masak
04:37 eythian joined
masak (note that the space after `say` is essential: the parens denote a sub-statement, not an argument list) 04:37

evalable6 (42 77)
hythm have to .join to get the correct matched numbers, is ther a way to make $<x> holds all <digit> values, and return this as one number, '42' instead of '4, 2'? I though using <.digit> will do that 07:28

pistacchio_ if I remember correctly, someone has a page where he's been running daily benchmarks of Rakudo's releases using the same algorithm everyday. can you given the link? 10:58

antoniogamiz sorry for the repeated message 11:07
11:10 pistacchio_ left
jmerelo antoniogamiz: that one apparently benchmarks perl5 vs perl6 implementation. But thanks for the link... 11:16
timotimo it also benchmarks different perl6 implementations and different versions of the same perl6 implementation 11:17
jmerelo timotimo: the speed increase is really amazing... 100x increase, a 2x increase in the last year... 11:18
timotimo well, we started rather extremely slow 11:19
240 at the beginning ... i mean, wow
jmerelo timotimo: still, 2 seconds is not great. There's a lot of room for improvement. 11:20
timotimo yeah
jmerelo timotimo: hope your profiler helps find out more bottlenecks...
timotimo tux has been saying for years that making "next" faster would be a big help
jmerelo timotimo: what would you say about that? 11:21
timotimo that sounds likely 11:22
unfortunately it's also tricky
jmerelo timotimo: no other incremental path to improvement? 11:25
timotimo if somebody wants to manually rewrite some code in there to turn "next" into basically "loop { beginning of loop body ...; if not $condition-for-next { rest of the loop body } }" we could probably get an estimation of the potential speed improvement
i haven't looked into a profile or spesh log of that library for a while 11:26
right now i'm adding stats to the profiler that will tell you what objects die young, not quite as young, or old
i.e. for every gc run it'll tell you how many objects it freed of any given type and splits the count into "freed from nursery", "freed from nursery, but with the 'already seen in nursery' bit set", and "freed in the gen2" (which only happens in major collections) 11:27
jmerelo timotimo: would be useful for what? Early gc? Objects that are not really used? 11:28
timotimo one of the most expensive things you can have is an object that lives just barely long enough to reach the gen2, and then immediately becomes garbage
11:29 pecastro joined
timotimo other than that, objects that die young can be potential candidates for scalar replacement, but of course only if they are allocated and become garbage in the same frame, and don't escape 11:33

antoniogamiz some guide to publish new modules 19:02
?
sena_kun antoniogamiz, are you interested in module structure or making a module public/available? 19:07
antoniogamiz making a module public yep 19:08
19:09 [Sno] joined, |Sno| left
sena_kun antoniogamiz, right now there are at least two popular options: CPAN and github. Unfortunately, I am not familiar with CPAN, so maybe someone else can tell more. As far as I know, you have to make an account, prepare your module distribution and upload it, but again, not my thing. The easier thing is to just make a PR for github.com/perl6/ecosystem <- you have to add url to your `META6.json` file and once it's accepted that's it. 19:09
19:10 SCHAPiE left
antoniogamiz ah ok, that's what I needed to know! thanks :) 19:10
I already have the repo done: github.com/antoniogamiz/Math-ConvergenceMethods 19:11
I will make the pr then
sena_kun just an edit of META.list file with one more URL. You want a link to raw file in your repo, but in any case it is pretty tested and people are checking this repo, so if there will be any issues, you'll get help. :)
antoniogamiz, also, you can check if that's installable locally using `zef install .` in the module directory. Saves time if there are any immediate issues like wrong paths and the like. 19:12
antoniogamiz ok, I will check that :)
