disbot <simon_sibl> is there a way to do a "last" or "return" in a tap block ? to just stop going further if a condition is met (but still execute next time a emit happens) 06:30
<rcmlz> I remember we discussed that here. But I forgot. Could you do a minimal example of your current aporoach in e.g. glot.io such that it is easy to „run and play“ by people that want to help? 07:00
<rcmlz> Ideally that minimal code has a few tests attached - although I guess that testing async code is hard, even in Raku :-) 07:02
<rcmlz> @simon_sibl with regards to guix and recent Rakudo+zef. Perhaps you should ping the people that did the previous definition. I guess the intersection of people using Raku and Guix is not that big. Booth not mainstream (yet). 07:07
<simon_sibl> I just realized that last works but the issue is that in my code the condition happens within multiple layer of scope 07:08
<simon_sibl> basically I am not happy with how I deal with this part: github.com/4zv4l/rakubin/blob/2ebf...n.raku#L98
<simon_sibl> I wish I could simply do a "next client" if the data is too big, rather than setting data to "" and continue 07:09
<simon_sibl> I am currently in a pull request discussion to update Rakudo on Guix 07:10
<simon_sibl> nice website btw ! thanks for the info 07:16

disbot <rcmlz> I beliefe that fostering „Please show a minimal example illustrating your problem in a „the most easy runable way“ and make you intentions crystal clear by using testcases“ is a good way to get qualified feedback. 08:34

disbot <simon_sibl> I will try to follow this, thanks ! 08:58

disbot <antononcube> Donnie Darko related? 09:37
<simon_sibl> Donnie Darko ? 09:44
<simon_sibl> If that’s about the movie, I haven’t watched it (yet?) 😆 09:45

disbot <simon_sibl> for the IDs I've got a better idea but not sure how to implement this in good looking Raku basically I give a charset ('a'..'z','A'..'Z',0..9) and I would like a lazy list that do a, b, c ..., aa, ab, ac, ... etc. indefinitely 11:33
11:33 arkiuat left
disbot <simon_sibl> actually bad idea, then people could "guess" other's people paste 11:41
<simon_sibl> or if that works, is it possible to "pick" from an infinite lazy list ? so that it never takes twice the same 11:42
<simon_sibl> m: (0...Inf).pick(5) 11:44
<Raku eval> Exit code: 1 Cannot .pick from a lazy list onto a List in block <unit> at main.raku line 1
<simon_sibl> oh well
lizmat .pick already guarantees not picking the same value more than once 11:45
as opposed to .roll
11:48 arkiuat joined
disbot <simon_sibl> yes but I would like to use it on a Lazy "unlimited" list 11:50
<simon_sibl> I am trying to find a way to generate random ID without collision
<simon_sibl> currently I use "roll" on a list and then I append the "time"
<simon_sibl> but its a bit long
lizmat m: use v6.e; say (^99999999).roll ~ nano 11:52
camelia ===SORRY!=== Error while compiling <tmp>
Raku v6.e requires PREVIEW modifier
at <tmp>:1
------> use v6.e<HERE>; say (^99999999).roll ~ nano
11:52 arkiuat left
lizmat m: use v6.e.PREVIEW; say (^99999999).roll ~ nano 11:52
camelia 831959741756986766055807101
lizmat m: use v6.e.PREVIEW; say (^99999999).roll ~ nano
camelia 199170751756986769220511769
disbot <simon_sibl> yeah I thought about nano, but the ID is very long xD 11:58
lizmat if you intend to pick random from 0 to infinity, that's still pretty small :- 12:17

disbot <simon_sibl> m: (^5000).pick(5) 12:54
<Raku eval>
<simon_sibl> cool
<simon_sibl> if I do this in a loop, how could I maintain a state ? 12:56
<simon_sibl> oh I know
<simon_sibl> m: say (^5).pick(*) 12:57
<Raku eval> (4 2 3 0 1)
<simon_sibl> then I just gather take on this
13:01 arkiuat joined 13:05 arkiuat left
disbot <simon_sibl> not great but 13:24
<simon_sibl> my @IDs = ('a'..'z','A'..'Z',0..9).flat.combinations(4).pick(*); # paste IDs
<simon_sibl> I will make an array like this, and pop it until its not possible xD

disbot <simon_sibl> alright, added a "garbage collector" and a alright ID system 16:02
