Kiryl Dziamura (Feb 02 2024 at 23:04): Kiryl Dziamura (Feb 02 2024 at 23:04):Is it possible to import a custom ability? When I try to do this, I get the following
An internal compiler expectation was broken.
This is definitely a compiler bug.
Please file an issue here: https://github.com/roc-lang/roc/issues/new/choose

Did you expose each of the member functions?
Brendan Hansknecht (Feb 02 2024 at 23:06):You have to expose the ability itself and each function in the ability to be able to import and use them in another module.
Kiryl Dziamura (Feb 02 2024 at 23:11):Is there an example? Because it seems I exposed everything
Brendan Hansknecht (Feb 02 2024 at 23:14):Should be the same as what is done in the standard library for hash, for example. Or I did it here with Arbitrary.
Kiryl Dziamura (Feb 02 2024 at 23:14):ah, wait a sec. It seems I understood. ok, I'll create a ticket for better logging then
Luke Boswell (Feb 02 2024 at 23:21):Sounds similar to https://github.com/roc-lang/roc/issues/6094
Kiryl Dziamura (Feb 02 2024 at 23:25):Made a comment there in case anyone encountered the same problem. Thank you
Luke Boswell (Feb 02 2024 at 23:32):Oh nice, didn't know about that workaround
Luke Boswell (Feb 02 2024 at 23:32):Or maybe that is the desired behaviour
