| librasteve | f(2) == &f(2) == &f.(2) you can make any sub be a method and you can use the dot (“methodop”) before the parents it’s analogous to something like .= | 07:35 | |
| or @a[2] == @a.[2] and %h<b> == %h.<b> | 07:37 | ||
| that way you can apply meta operators like the hyper >> | 07:38 | ||

| nemokosch | I think there is a postcircumfix .() operator which in term performs a function call | 09:20 | |
| eventually the RakuAST parse will help analyze things like that; right now I'm more confident with raku --target=parse | 09:21 | ||
| this unfolds that (as of the non-RakuAST grammar), you get a dotty token which contains a single dottyop token which in turn contains a dot and a postop token | 09:33 | ||
| when the match is processed, it will be simply codegenned as the postop part | |||
| so I think it's safe to say that the whole business is for "disambiguation" | 09:34 | ||
| snonux | anyone knows if there is a good LSP (language server) for Raku, which could be plugged into editors such as NeoVim, VSCode, Helix..? i did some googling, there seems to be something for VSCode, but not sure if that could be used for NeoVim. | 12:02 | |

| nemokosch | I think bscan's LSP is still the best option | 12:25 | |

| snonux | i don't node/typescript so well, but i managed to get it running in Helix :-) thanks! | 12:48 | |

| antononcube | @nemokosch and @librasteve Thanks! | 13:18 | |
| @librasteve I strongly consider using your units package(s) to demonstrate some functionalities of LLMs. As far as I can tell you have implemented a full algebra for units manipulation. Do you special objects for holding k-number of units? E.g. something like quantity(5.4, GetUnit(“m / s^2). | 13:46 | ||
| librasteve | use Physics::Measure :ALL; my $acc = ♎️'5.4 m / s^2'; my $time = 8s; my $vel = $acc * $time; say $vel; dd $acc; dd $vel; | 21:31 | |
| 43.2m/s | |||
| ^^ try that | 21:32 | ||
| Speed $vel = Physics::Measure::Speed.new(value => 43.2, units => Unit.new( factor => 1, offset => 0, defn => 'm/s', type => Speed, dims => [1,0,-1,0,0,0,0,0], dmix => ("m"=>1,"s"=>-1).MixHash, names => ['m/s'] ); , error => Error) | 21:34 | ||
| antononcube | @librasteve Why "Physics::Measure" depends on "SVG::Plot" ? (Sorry, I am too lazy to look into the source code.) | 21:37 | |

| antononcube | I remember this -- while reading / scanning it I started thinking "how to imlement random mandlas plots in Raku?" | 21:41 | |
| habere-et-disper | Instead of : | 21:43 | |
| multi foo ( 0 ) { 0 } | |||
| multi foo ( 1 ) { 1 } | |||
| Can I write two base cases together something like this : | |||
| m: multi foo ( 0 | 1 ) { $_ } | |||
| camelia | ===SORRY!=== Error while compiling <tmp> Malformed parameter at <tmp>:1 ------> multi foo ( 0 |⏏ 1 ) { $_ } expecting any of: constraint |
||
| librasteve | m: subset ohone of Int where 0|1; multi bar(ohone $x) {7}; say bar 1; say bar 7; | 21:49 | |
| Raku eval | 7 Exit code: 1 Cannot resolve caller bar(7); none of these signatures matches: (Int $x where { ... }) in block <unit> at main.raku line 1 | ||
| librasteve | m: sub baz( $x where 0|1 ) {'ok'}; say baz 0; | 21:51 | |
| Raku eval | ok | ||
| habere-et-disper | Subset -- ah great thanks @librasteve | 22:54 | |
