This is a Haskell package repository containing patched packages from Hackage for use with GHC prereleases.

The source of this package repository is at gitlab.haskell.org/ghc/head.hackage.

To use package repository with cabal-install add the following to your project's cabal.project.local and run cabal v2-update: (consider using scripts/head.hackage.sh update as v2-update is broken, Cabal bug #5952)

repository head.hackage.ghc.haskell.org
   url: https://ghc.gitlab.haskell.org/head.hackage/
   secure: True
   key-threshold: 3

Finally, you may want to add the constraints to your project to ensure that cabal chooses the patched releases.

If you find a package that doesn't build with a recent GHC pre-release see the contributor documentation for instructions on how to contribute a patch.

If you encounter other trouble refer to the head.hackage documentation or let us know.

You might also be interested in referring to the CI build results of the build that gave rise to this repository.
