17:01 <FromGitter> <tarbetu:matrix.org> Heya. Is there anyway to export crystal classes into Python?

17:01 <FromGitter> <Blacksmoke16> no

17:02 <FromGitter> <tarbetu:matrix.org> Can't Crystal export any bindings?

17:05 <FromGitter> <tarbetu:matrix.org> Oh, this was a short answer. :) Anyway, it seems crystal classes can be exported into ruby.

17:05 <FromGitter> <Blacksmoke16> in some cases yes, but usually no

17:06 <FromGitter> <tarbetu:matrix.org> But why?

17:06 <FromGitter> <Blacksmoke16> ```class Foo ⏎ def run ⏎ "foo" ⏎ end ⏎ end``` ⏎ ⏎ is valid Ruby and Crystal [https://gitter.im/crystal-lang/crystal?at=6134f9194c7be06b79a03252]

17:06 <FromGitter> <Blacksmoke16> but once you start adding type restrictions to things like: ⏎ ⏎ ```class Foo ⏎ def run : String ⏎ "foo" ⏎ end ⏎ end``` ⏎ ⏎ This is only valid Crystal [https://gitter.im/crystal-lang/crystal?at=6134f931d9a141754dd4a5de]

17:07 <FromGitter> <Blacksmoke16> because Ruby doesn't have that concept, so would be invalid Ruby syntax

17:09 <FromGitter> <Blacksmoke16> but by export i assume you mean copy/paste?

17:09 <FromGitter> <tarbetu:matrix.org> Oh, I mean the binding between this languages.

17:10 <FromGitter> <Blacksmoke16> officially Crystal only supports C bindings afaik

17:11 <FromGitter> <tarbetu:matrix.org> How about this project? https://github.com/Anyolite/anyolite

17:11 <FromGitter> <Blacksmoke16> i didnt say it was impossible, just that it's not an official feature of the lang. I.e. not built-in

17:12 <FromGitter> <Blacksmoke16> if there's a shard to do what you're wanting, that's great

17:15 <FromGitter> <jrei:matrix.org> Good luck trying to embed CPython :)

17:15 <FromGitter> <tarbetu:matrix.org> Oh, thanks anyway :) I would like to call Crystal methods from python.

17:16 <FromGitter> <Blacksmoke16> good luck ;P

17:16 <FromGitter> <jrei:matrix.org> However will be simpler probably with pypy or other alternative interpreters

17:17 <FromGitter> <Blacksmoke16> any reason you cant just use Crystal for everything? 😉

17:18 <FromGitter> <jrei:matrix.org> Would be too simple haha 😂

17:19 <FromGitter> <jrei:matrix.org> At least use Ruby :3

17:21 <FromGitter> <jfontan:matrix.org> You can make a crystal server and send RPCs to it from python or ruby

17:22 <FromGitter> <jrei:matrix.org> That'a good solution, I've done this with JavaScript <-> Crystal

17:23 <FromGitter> <jrei:matrix.org> Though it's best to auto generate message classes for both ends to avoid any errors

17:26 <FromGitter> <jfontan:matrix.org> grpc may be useful but I've never tried it with crystal

18:43 <FromGitter> <jrei:matrix.org> Does someone have an idea of what's going on here? https://carc.in/#/r/bvnb

18:46 <FromGitter> <Blacksmoke16> i think the interface expects there not to be any yielded args, while your implementation has 1

18:50 <FromGitter> <jrei:matrix.org> I see, strange: https://carc.in/#/r/bvnm

18:51 <FromGitter> <jrei:matrix.org> Remove the `self.` before the `a.`, still error.

18:51 <FromGitter> <jrei:matrix.org> Strange that module are less strict than class/structs

18:51 <FromGitter> <Blacksmoke16> well for one you cant have abstract class methods

18:52 <FromGitter> <jrei:matrix.org> yeah I know, but error still there in any case

18:52 <FromGitter> <jrei:matrix.org> ha ok for modules

18:52 <FromGitter> <Blacksmoke16> https://carc.in/#/r/bvnt

18:53 <FromGitter> <jrei:matrix.org> I should use ectend, forgot it

18:54 <FromGitter> <jrei:matrix.org> interfaces are really not ideal :/

18:54 <FromGitter> <Blacksmoke16> depends on the use case

18:56 <FromGitter> <jrei:matrix.org> If you want an interface which for class and instance methods, it becomes messy

18:57 <FromGitter> <Blacksmoke16> could have macro included hook on the interface that extends another class interface module :shrug:

18:59 <FromGitter> <jrei:matrix.org> probably... the API docs won't be as clear "Take case to also implement methods in X"

19:02 <FromGitter> <jrei:matrix.org> generics can also be used to some extent

19:02 <FromGitter> <Blacksmoke16> related https://github.com/crystal-lang/crystal/issues/5956

19:05 <FromGitter> <jrei:matrix.org> Thanks!
