hackageTarball :: IO FilePath #

Determine the default path of the Hackage database, which typically resides in $HOME/.cabal/packages/hackage.haskell.org/. Running the command cabal update or cabal v2-update will keep the index up-to-date.

See cabalStateDir on how hackage-db searches for the cabal state directory.
