p6steve i'm thinking about Dan::Polars - raku polars <-> rust polars <-> arrow2 ... this implies getting raku <-> rust working ... is there any prior art I can "borrow"? 19:07
[coda: does NativeCall use FFI? if so -- would this guide doc.rust-lang.org/nomicon/ffi.html hold for the rust side of things?] 19:09
please ;-) 19:16

grondilu m: role R[Hash $h] { has %.h = %$h }; say class :: does R[%(foo => "bar")] {}.new.h 19:41
camelia {foo => bar}
grondilu and yet: 19:42
m: role R[Hash $h] { has %.h = %$h }; my $h = %(foo => "bar"); say class :: does R[$h] {}.new.h
camelia ===SORRY!=== Error while compiling <tmp>
No appropriate parametric role variant available for 'R':
Cannot resolve caller (<anon|1>, Any:U); none of these signatures matches:

grondilu what is different in these two lines?

grondilu m: role R[Hash $h] { has %.h = %$h }; my $h = %(foo => "bar"); say class :: does R[$h.Hash] {}.new.h
camelia {}
p6steve ^^^ yikes - this worked(!) - thinking perl5 maybe adequate route to rust (comments / alternatives welcome please) 19:46
grondilu is it too much to put a hash as a parameter for a role or something?
tonyo can you rephrase that q p6steve ? 19:47
tellable6 2022-05-02T13:10:00Z #raku-dev <carlmasak> tonyo the thing that would make me consider Haskell's package management a significant step up from Go's isn't some technicalities around go.mod, but how well it solves the "stable dependencies" problem.
tonyo .tell carlmasak agreed (re:haskell's stability in dependencies) 19:48
tellable6 tonyo, I'll pass your message to carlmasak
Voldenet m: role R[Hash $h] { has %.h = %$h }; my $h = %(foo => "bar"); say (class :: {}.new but R[$h]).h 19:51
camelia {foo => bar}
Voldenet role R[$h] { has $.h = $h }; my Hash $h = %(foo => "bar"); say class :: does R[BEGIN { say $h; $h }] {}.new.h 19:52
evalable6 (Hash)
p6steve tonyo: sure - I want to write a new raku module that implements raku Dan (github.com/p6steve/raku-Dan) in the fast Apache Arrow2 library - since Dan is a raku alternative to Pandas/Polars Series & DataFrames, I think that it would be less work to interface Dan to Polars (which is implemented in Rust) 19:53
grondilu Voldenet: oh yeah, the parameter has to be defined at class composition time or something. of course. 19:54
Voldenet I suspect that's the case
p6steve soooo - my question is "are there any examples of interfacing raku to rust - for example via FFI?" and "does the info at guide doc.rust-lang.org/nomicon/ffi.html fit that from the rust side?" 19:55
19:57 sena_kun left
p6steve appreciate any guidance 19:58
19:59 sena_kun joined
nine If that Rust library exposes a C interface, I can imagine that just working as is via NativeCall 20:04
p6steve nine: tx! I suppose my base ignorance is that I do not know if NativeCall does FFI, or whether that matters? 20:08
nine What do you mean with "FFI"? 20:11
20:12 n1to joined
p6steve nine: I mean this --> en.wikipedia.org/wiki/Foreign_func..._interface 20:15
nine: (but I wonder if this is just what raku does anyhow - and thus I am confused) 20:16
nine That's why the question confuses me. Of course NativeCall is a foreign function interface. It is how you call native (i.e. non-Raku) functions from Raku 20:17
[Coke] bscan: what would a json version of the docs look like? 20:19
Is there some object standard for that? 20:20
p6steve haha - well the Platypus I shared above has a rust example like this: 20:21
1 #![crate_type = "dylib"]
3 // compile with: rustc add.rs
5 #[no_mangle]
6 pub extern "C" fn add(a:i32, b:i32) -> i32 {
7 a+b
8 }
this makes 'libadd.so' 20:22
so I will just go for that with NativeCall ... and see how I get on! 20:23
I [almost] want to use P5 Platypus as a go-between ... but will resist the urge to go too fast and loose 20:26
nine: vielen dank 20:30

Xliff p6steve: As long as your library is a valid .so, NativeCall will run it. 21:41
So for that particular function it would be... "use NativeCall; sub add (int32, int32) returns int32 is native(add) { * } 21:42
Voldenet I don't think you need (add) in that case 21:45

p6steve Xliff: Cannot resolve caller guess_library_name(Nil:U, Nil:U); none of these signatures matches: ... suppose I need to "use" libadd.so somehow? 22:03
Xliff: Cannot locate native library 'libadd.so': libadd.so: cannot open shared object file: No such file or directory 22:05
^^ this with native('add') 22:06
Xliff: 1 use NativeCall; sub add (int32, int32) returns int32 is native('add') { * }; say add(1, 2); 22:09
Xliff: 3
Xliff: (had to cp libadd.so /usr/lib) 22:10
Xliff: cool - thanks!!
22:11 hankache left 22:35 jjido left
Voldenet p6steve: you don't need to have libadd.so in /usr/lib - you can provide full path iirc 22:42
> The native trait accepts the library name, the full path, or a subroutine returning either of the two. When using the library name, the name is assumed to be prepended with lib and appended with .so (or just appended with .dll on Windows), and will be searched for in the paths in the LD_LIBRARY_PATH (PATH on Windows) environment variable. 22:43
