cabal install implicit-hie command fails for ghc2021 and ghc2024

Hi,

I'm trying to setup haskell IDE in neovim.

I would like to generate hie.yaml file using implicit-hie https://hackage.haskell.org/package/implicit-hie.

I can only install (cabal install implicit-hie) for cabal project and Haskell 2010 version.

The above command fails for GHC2021 and GHC2024.

Steps to recreate -

1. cabal init new-project
2. choose Haskell2010
3. Run cabal install implicit-hie

This is should work fine.

1. cabal init new-project
2. choose GHC2021
3. Run cabal install implicit-hie
   This should fail

I am not sure implicit-hie is needed with hls these days.
I believe the automatic cabal cradle hls uses should just work.
What issues are you running into using hls without a hie.yaml file?

If you do need it to work with modern Haskell PRs welcome.

Hi!

Fyi, implicit-hie is still used by HLS for stack cradles. If you are not using stack, implicit-hie shouldn't be necessary any more.

Oh shoot, I'll try and upgrade it then.

No hurry from the HLS side, if it had been a blocker for HLS, we would have provided PRs already!
