| lizmat | SmokeMachine++ # all fixed now, including being able to mention the editor on the command line | 08:18 | |
| Nemokosch | japhb: nice, thank you | 08:46 | |
| can confirm that it's typing-friendly now | 08:47 | ||
| I've been thinking about the Raku conference, by the way | 08:58 | ||
| lizmat | Nemokosch: a presentation would be cool :-) | ||
| tellable6 | lizmat, I'll pass your message to Nemokosch | ||
| Nemokosch | Yes yes... but about what? It has been bugging me for days now | 09:00 | |
| And I think what really would be the best is a presentation about containers - but I don't think I can just master them in a month | |||

| lizmat | containers in the sense of my $foo being a container, or more the Docker kind ? | 09:13 | |
| Nemokosch | the first | 09:18 | |
| I don't think there is much Raku specific about the Docker kind | |||
| lizmat | you know of my opensource.com posts about containers? | 09:20 | |
| opensource.com/article/18/8/containers-perl-6 | 09:22 | ||
| Nemokosch | Not sure | ||

| Okay, nice | 10:12 | ||
| Is there anything that doesn't essentially bind to something? | |||
| lizmat | ? | 10:15 | |
| don't think so: essentially, it's all built on NQP, and NQP only knows binding | |||
| Nemokosch | This article is not bad but well, it misses @ % and \ at least 😅 | 10:27 | |
| I read something in the docs that \foo = something and \foo := something are the same | 10:29 | ||
| that is, sigilless variables bind, no matter what | |||
| also docs.raku.org/routine/%3C%3E | 10:31 | ||
| "decontainerization operator" | |||
| is this not the same as zen-slicing? | |||

| summer | Quick question about bad ideas: gist.github.com/Summertime/7d768d9...705b60666c could such a thing be done with raku's type system? | 12:26 | |
| (and or, any currently existing language?) | 12:27 | ||
| Kaiepi | summer, that looks a bit like Rc from rust | 12:29 | |
| something similar should be doable with a Proxy | 12:30 | ||
| you're gonna have a bad time if you try the mop route. attributes are gorey | 12:32 | ||
| i.e. attribute references are rarely made with Attribute.get_value or set_value internally, so you'd need a slang of some sort | 12:34 | ||
| summer | a proxy would fire twice, which would mean either an eager "grab everything" api call, or two api calls | 12:37 | |
| from my understanding | |||
| and yeah its somewhat expected to be gorey, unfortunately. I just wish the docs on the gore didn't go so quickly into "some of this stuff is compiler specific" :sob: | 12:38 | ||
| I would be happy still if I could do something like, user.^needs('attribute') or the such, just as long as the attribute-requesting-code is close to the attribute-using-code | 12:40 | ||
| I'll look into Rc | |||
| I guess the shortest worded form of what I'm asking is "can the type system be used to optimise an API call" | 12:42 | ||

| Nemokosch | Is Array the data type and Array the container type the same thing? | 13:35 | |
| lizmat | no, containers come in many flavours | 13:37 | |
| the Proxy class e.g. also provides a container | 13:38 | ||
| Nemokosch | what would be a containerless Array, then? | 13:39 | |
|
13:40
Nemokosch joined
|
|||
| Nemokosch | m: my \bed = <too big>.Array; bed = 'full'; dd bed; | 13:41 | |
| camelia | ["full"] | ||
| lizmat | m: my @a; @a[0] := 42; @a[0] = 666 # a containerless Array | ||
| Nemokosch | crazy stuff | ||
| camelia | Cannot assign to an immutable value in block <unit> at <tmp> line 1 |
||
| Nemokosch | that's not the array but the element | 13:42 | |
| lizmat | you cannot define a containerless Array you can only make elements containerless | 13:43 | |
| or define your own Array compatible class | |||
| Nemokosch | hmm, I mean... I guess you can see why this is causing massive headaches | 13:52 | |
| data types and container types aren't the same thing but they also aren't orthogonal | |||
| I suppose the same thing applies to Hashes as well | 13:56 | ||
|

|
|||
| lizmat | Nemokosch: yes | 14:22 | |
| Nemokosch | the key part cannot be a Scalar, at least it seems to me | 14:23 | |
| lizmat | indeed | 14:36 | |

| p6steve | i have v1 of the Dan::Polars read_csv ... to_dataset basically functional | 14:44 | |
| good news is that it will import a csv with 2 million rows in 2mins 14sec | 14:46 | ||
| bad news is this is 3sec for Rust to read the file and 2mins 11sec to import to raku :C (<= note use of Coercion type saddie) | |||
| there is probably quite a lot to be done to speed things up ... ideally would be a zero copy from Rust | 14:48 | ||
| I think that means building a Cstruct in Rust that matches a raku (2d) Array | |||
| is there any prior art on this -- other modules or in Nativecall maybe? | 14:50 | ||
| (funnily enough a containerless array might be ideal for this to save creating 28 million containers | |||
| ) | |||
| lizmat | I guess it could be relatively trivial if you're talking about a native 2d array | ||
| what's in the containers? Ints ? | 14:51 | ||
|
14:51
euandreh left
|
|||
| p6steve | hmmm - well this is Polars DataFrames where each column is a typed Series | 14:52 | |
| SmokeMachine | Is it `hyper`ing the CSV lines? | ||
| p6steve | so I guess can drop each Series (i32, f64 and so on) into a specific raku (1d) Array variant with known native type | 14:54 | |
| smokemachine: not yet ... hypering is one strategy ... BUT early on in the import I get a zero copy pointer to a CArray(int32) or similar and AFAIK ```my@a = CArray.list``` is the only way to load the array | 14:56 | ||
| smokemachine: only Rust Polars gets to handle the csv file ... it's a Polars Series by the time I start the raku import | 14:58 | ||
| lizmat: where should I look in rakudo / moarvm for the 1d Array layout? | 14:59 | ||
| this is all a bit down and dirty for my skill set | 15:00 | ||
| lizmat | good question: it's all hidden in nqp ops I believe | ||
| lizmat wouldn't know offhand | |||
| nine vrurg might | |||
| need to go afk now& | 15:01 | ||
| p6steve | tx! - probably needs a bit of digging & speed profiling & maybe an SO question or two | 15:27 | |
