| Nemokosch | SmokeMachine: how does ^all work? 🙂 | 07:31 | |
| SmokeMachine | Nemokosch: ^all returns a ResultSeq | 07:38 | |
| tellable6 | SmokeMachine, I'll pass your message to Nemokosch | ||
| Nemokosch | what is a ResultSeq? | 07:39 | |
| SmokeMachine | It is a Sequence that stores everything needed to generate SQL and generates it and run it when iterated over | 07:43 | |
| And it has many methods (like map and grep) that returns new ResultSeqs | |||

| Nemokosch | it would be funny to make a Raku Hall of Fame, I mentioned that yesterday as well. At least half of yesterday's speakers would be there 😄 | 09:02 | |
| From Liz to Vadim straight, basically | |||
| And I'd like to think that there will be eventually space for all the others as well, it's just a matter of time and dedication | 09:04 | ||
| SmokeMachine | Nemokosch: did you understand ResultSeq? (Sorry, I’m checking it in long intervals… I’m at the coliseum today… :) | 09:05 | |
| tellable6 | SmokeMachine, I'll pass your message to Nemokosch | ||
| Nemokosch | I think so. So this inherits from Seq? | 09:12 | |
| SmokeMachine | It does Sequence and Positional | 09:16 | |
| And it has a .Seq method that returns a Seq | 09:17 | ||

| SmokeMachine | Nemokosch: you can try playing with ResultSeqs if you want… `use Red; model Bla { has $!id is serial; has Int $.value }; red-defaults “SQLite”; my $*RED-DEBUG = True; Bla.^create: :value(^100 .pick) xx 10; .say for Bla.^all.grep(*.id < 30).map: *.value` something like this will use in memory SQLite and print the generated SQL… | 09:35 | |
| tellable6 | SmokeMachine, I'll pass your message to Nemokosch | ||
| Voldenet | I really like 30 lines of `use` in that file, makes me wish that `use Red::Ast::<Next Case Empty Value …>` was possible | 09:36 | |
| Nemokosch | I think it will take time until I start using a database from Raku | 09:39 | |
| Simply because it doesn't really fall into my domain. Right now I'm only using database 1. from crazyass C-generated code for work 2. with node.js for hobby, there I use Sequelize and Umzug | |||
| with a tiny sqlite database | |||
| SmokeMachine | Voldenet: I think that would be cool | 09:40 | |
| Nemokosch: that’s a good way for understanding ResultSeq | 09:41 | ||
| tellable6 | SmokeMachine, I'll pass your message to Nemokosch | ||
| Voldenet | sounds like "if I had rakuast" case, but I'm not sure if such macros can be made | 09:50 | |
| leont | Voldenet: funny you mention that (30 lines), that's one of the things on my list that annoy me | 09:52 | |
| SmokeMachine | Voldenet: I’m planning using custom passes for that | 09:54 | |
| Even if I have to add a new ast attribute on Block and populate it for each block passed for each map, grep, first, etc… | 09:56 | ||
| leont | 3 more hours, and my head is still fried. Might have to cancel. And beginning to worry it's not the heat but covid or something :-s. | 09:58 | |
| lizmat | leont: actually, 5 hours | ||
| 15:00 UTC | |||
| which is 17:00 local | |||
| Voldenet | though the newest C# solves `the great totem of usings` differently – it just uses file with shared usings per project | 09:59 | |
| leont | Right. That helps a little. | ||
| Nemokosch | I still don't know if I like "partial classes" for example, now that you mentioned C# | 10:00 | |
| Voldenet | partial classes are a solution to the problem, where half of the code is generated and half is maintained | 10:01 | |
| Nemokosch | I mean, it's better than nothing, but it's mostly a way to hide language constraints and bad class design | 10:02 | |
| I'm not sure if I like "half of the code is generated and half is maintained" in the first place | |||
| 😄 | |||
| Voldenet | "good tradeoffs, bad tradeoffs" case :D | ||
| Tooling for UI or translations (also third party ones) extensively use that | 10:03 | ||
| but it could've been done on language level with something like `class Translation { include Resx.Create("1033.resx") }` | 10:06 | ||
| IMO it actually makes tools easier | 10:08 | ||
| because it's relatively simple to just generate code files, dealing with metamodel requires knowing metamodel otoh | 10:09 | ||
| Nemokosch | Anyway, I'm looking forward to seeing what RakuAST has for us | 10:18 | |
| Because there might be other ways with this very much language-aware design | |||
| Voldenet | also amazing, because you no longer will have to sacrifice performance for readability or other way around | 10:30 | |

| lizmat | leont: did you make an issue for "is built" not handling capturization correctly? | 17:24 | |
| leont | Not yet | 17:25 | |
| lizmat | imo if an attribute is built, it should be captured | ||
| or do you have a situation where you would want to build, but not capture ? | |||
|

Furor is now known as Colere
|
|||
| guifa_ | leont I really appreciated the talk, I don't think you were being negative at all. Some of them (like pod, which has been very under utilized so far), have a lot of room to be potentially reworked down | 17:32 | |
| leont | That one kind of ties in with the exporter one though, because right now other modules can't affect POD in a direct way, leading one to have to write a bunch of boilerplate that I hope won't be necessary in the future | 17:34 | |
| E.g. being able to inject a DOC phaser would be super useful | 17:35 | ||
| lizmat | use module $=pod | 17:37 | |
| would allow access to "module" to the pod of a module doing the "use" statement ? | |||
| if it's the last statement in a compunit, of course | 17:38 | ||

| leont | I also think we could use a few more pod variables. E.g. instead of pushing declaration blocks straight to $=pod it would use some &=process-declaration that defaults to the current behavior but can easily be overridden. | 21:07 | |

| SmokeMachine | leont: I’m watching your talk… the Red’s user doesn’t need to include any of those files… only `use Red` is needed… | 22:17 | |
| Red does exports everything needed by the user | 22:19 | ||
| leont: it’s done here (github.com/FCO/Red/blob/master/lib/Red.pm6). Red chooses what to export from several different things… | 22:21 | ||
| leont: the tooling you say you’d want to have, is what Red does to the user… | 22:22 | ||
| leont | I certainly didn't mean to pick on Red, but I encountered an example of having to include way too much stuff and used it for the presentation. | 22:23 | |
| SmokeMachine | leont: and just for completeness: Red internals are not visible for the user… all the user should know is `use Red:api<2>` | 22:24 | |
| leont | Yeah, that's what saves you | 22:25 | |
| Anything that needs to expose more internals (e.g. Cro) will suffer from the issue much more | |||
| SmokeMachine | And I really think the solution on Red.pm6 was a relatively good one for avoiding the user to add many uses… | 22:26 | |
| (I had that issue to not make the users to have it :) ) | 22:27 | ||

| guifa_ | One thing I've been trying to do lately (and maybe it's me trying too hard) is to do lexical use statements | 23:44 | |
| In some cases, that can really help me clear up the laundry list of `use`, while also making it a bit clearer where/why I'm `use`-ing stuff | 23:45 | ||
