How can you use it there? It'd be a cyclic dependency.

This is for haskell-flake. There are in total 3 places where I am using cabal.nix
- While setting output_filename for
cabal2nixpre-commit - While setting exclude for
nixpkgs-fmt - For haskell-flake to refer to the cached
cabal2nixfile
In this particular case I was talking about 3.
ideally we can set at one place use it at all other places.

Oh, right, you can just reuse the module option (3) in both the palces (1 & 2). Good idea.
