The Haskell Platform (HP) is the name of the blessed, core library suite for Haskell. By taking the best libraries from the more than 1200 libraries of Hackage, it provides a comprehensive, stable and mature base for Haskell projects to work from.

See the Platform Issue Tracker for further information.


The platform is specified via a Cabal file:

The initial release targets, 2009.2.0

  • ghc-6.10.2
  • Classic Extra Libs
  • haddock, happy and alex
  • cabal-install and its dependencies.

Volunteers needed!

The platform requires installer developers, and distro maintainers, for every OS distro we care about. If you are able to help out on your system, please sign up to the mailing list, or drop by #ghc @ freenode.



Distribution format

  • Source distribution
  • .tar.gz bundle compatible with extra-libs
  • Windows Installed
  • Native distro packages

The HP will be the first meta-package on hackage, that depends on the platform library set. With this,

   cabal install haskell-platform

will be possible.


The initial release is expected to include only BSD3 licensed software.


The platform includes programs, such as haddock or cabal-install. These aren't nicely tracked from the cabal meta package yet.
