Cabal cradle doesn't recognize foreign-library sections

[cdsmith]

I was attempting to follow the tutorial at https://nokomprendo.gitlab.io/posts/tuto_075/2021-09-12-fr-README.html

HLS is flagging the Binding module with Multi Cradle: no prefixes matched. The module is listed in the other-modules section of a foreign-library section in the cabal file, as follows:

foreign-library fibohs
    type:               native-shared
    cc-options:         -std=c++17
    c-sources:          cbits/binding.cpp
    install-includes:   cbits/binding.hpp
    hs-source-dirs:     ffi
    build-depends:      ffi, base
    other-modules:      Binding

Does it work if you have a hie.yaml with

cradle:
  cabal:

in the root of your project?

[cdsmith]

Yes, it does work in that case!

Then that's a bug in https://github.com/Avi-D-coder/implicit-hie which is used by HLS when you don't have a hie.yaml

I'm creating the above minimal cradle for every new project, because implicit-hie has never worked for me.

[fendor]

Yeah, it is right in the most trivial cases, but unfortunately, not even in this repo it works for the tests.
This PR haskell/haskell-language-server#2342 defaults to the equivalent of cradle: {cabal: }, but it was never finished.

Filed Avi-D-coder/implicit-hie#44 over there. I'll close this now.
