| guifa2 is still waiting to make a crazy killer app combing Red, Cro and all the internationalization modules. Soon | 03:10 | ||

| SmokeMachine | I’ve spent many time thinking how should I express N-M relationship, and today I thought if it was a array of objs? How would o do it? Simple: $post.post-tags>>.tag; and that just worked as it should… I don’t think we should have any other syntax for that… | 03:19 | |
| guifa2 | SmokeMachine: I believe they call that the fruits of a well thought out design | 03:23 | |
| SmokeMachine | :) | 03:24 | |
| guifa2 | This feels … off | 03:42 | |

| Binding feels like it should be faster, but it's not. But my \foo = (value) is effectively binding anyways, right? | 03:45 | ||
| (I added an extra test just now for my $x := (value) and it's just as slow. The := operator seems to incur a huge performance penalty) | 03:46 | ||

| MasterDuke | guifa2: i think the optimizer is getting confused by the multiple loops in your example. if i run a single loop and then just change what it's doing, `$x :=`, `\x =`, and `\x :=` are all the same, `$x =` is roughly half as fast | 09:49 | |

| DinoAllo | Hello everyone! I am just getting start with Raku, and would like to set up Emacs as my main editor. Do any of the folks here use Emacs? | 13:22 | |
| I checked raku-mode and it was great. Are there any of Emacs packages that provide auto-complete feature for Raku? | 13:23 | ||
| For example, like a backend for company-mode | 13:25 | ||

| Altai-man_ | DinoAllo, there is raku-mode for emacs. | 14:03 | |
| DinoAllo, sadly, there is no abundance of emacs users around and raku is not so popular either, so it gives you less support. It's another deal if you write elisp and can contribute. :) | 14:04 | ||

| Altai-man_ | DinoAllo, no, I don't think you would! In fact, someone with time and able to give some love to emacs support is just awesome. I believe you can contribute to raku-mode if needed (the folks there are usually kind and easy to work with) or package something yourself if you need to, nothing much else is done in this area. | 14:23 | |
| MasterDuke | DinoAllo: colabti.org/irclogger/irclogger_lo...xt=checked will give you some names of other likely emacs users | 14:45 | |

| lizmat | interesting :-) | 15:48 | |
| hythm: I assume the size would be the size of the shaped array, and it should only allow 1-dimensional shaped arrays, right > | 15:49 | ||
| ? | |||
| hythm | correct. the 2 is a typo, i meant 1 | ||
| lizmat | I guess on a shaped array, we should be able to drop the size in the trait | 15:50 | |
| aka: my @a[42] is circular | 15:51 | ||
|
15:59
ManifestO left
16:02
Manifest0 joined
|
|||
| hythm | That would be better, since the size will be determined by the array shape anyway | 16:07 | |
| lizmat | yeah | 16:26 | |
| but that means an entirely different logic | |||
| will need to think about that | 16:27 | ||
| as shifting / splicing a shaped array is impossible at the nqp level | 16:33 | ||
| so push would mean iterating over the array and moving up all of the values by index | 16:34 | ||
| which would be.... slopw | |||
| *slow | |||
| so maybe it would be better to disallow "is circular" on shaped arrays altogether | 16:35 | ||
| because it wouldn't bring you anything semantically, and only cost you in performance | |||
|
16:40
guifa2 joined
|
|||
| hythm | understood. but is there any explanation to the error above? or whey is it assuming the the shaped array is a type obejct inside the trait-sub? | 16:40 | |

| hythm | Thanks lizmat, If you think this is a bug let me know and I can create an issue | 17:05 | |
| lizmat | creating an issue would help preventing this falling through the cracks :-) | ||
| hythm | and this would go to Rakudo or Array::Circular? | 17:06 | |
| lizmat | actually, both | 17:07 | |
| Array::Circular because it doesn''t support shaped arrays | |||
| and Rakudo because it passes a type object to the trait_mod | |||
| hythm | got it, thanks | ||

| It seems to work. | |||
| Yet after pointing that out to xentrunix, the poster of the Q, they have written "I made a simple question, "Is it possible to call Raku from C?" ... it seems it's not possible" | 22:10 | ||

| (And if there's substantive discussion related to them then a link to those could be added to the News after that?) | 22:15 | ||
| Q1. Are there any circumstances in which one can reliably call Raku code from C code? | |||
| In other words, does HåkonHægland's answer, which *appears* to work, actually work? | 22:16 | ||
