# Haskell packages in Nixpkgs
#
# If you have any questions about the packages defined here or how to
# contribute, please contact Andres Loeh.
#
# This file defines all packages that depend on GHC, the Glasgow Haskell
# compiler. They are usually distributed via Hackage, the central Haskell
# package repository. Since at least the libraries are incompatible between
# different compiler versions, the whole file is parameterized by the GHC
# that is being used. GHC itself is defined in all-packages.nix
#
# Note that next to the packages defined here, there is another way to build
# arbitrary packages from HackageDB in Nix, using the hack-nix tool that is
# developed by Marc Weber.
# -> http://github.com/MarcWeber/hack-nix. Read its README file.
#
#
# This file defines a function parameterized by the following:
#
#    pkgs:
#       the whole Nixpkgs (so that we can depend on non-Haskell packages)
#
#    newScope:
#       for redefining callPackage locally to resolve dependencies of
#       Haskell packages automatically
#
#    ghc:
#       the GHC version to be used for building the Haskell packages
#
#    prefFun:
#       version preferences for Haskell packages (see below)
#
#    enableLibraryProfiling:
#       Boolean flag indicating whether profiling libraries for all Haskell
#       packages should be built. If a library is to be built with profiling
#       enabled, its dependencies should have profiling enabled as well.
#       Therefore, this is implemented as a global flag.
#
#    modifyPrio:
#       Either the identity function or lowPrio is intended to be passed
#       here. The idea is that we can make a complete set of Haskell packages
#       have low priority from the outside.
#
#
# Policy for keeping multiple versions:
#
# We keep multiple versions for
#
#    * packages that are part of the Haskell Platform
#    * packages that are known to have severe interface changes
#
# For the packages where we keep multiple versions, version x.y.z is mapped
# to an attribute of name package_x_y_z and stored in a Nix expression called
# x.y.z.nix. There is no default.nix for such packages. There also is an
# attribute package that is defined to be self.package_x_y_z where x.y.z is
# the default version of the package. The global default can be overridden by
# passing a preferences function.
#
# For most packages, however, we keep only one version, and use default.nix.

{pkgs, newScope, ghc, prefFun, enableLibraryProfiling ? false, modifyPrio ? (x : x)}:

# We redefine callPackage to take into account the new scope. The optional
# modifyPrio argument can be set to lowPrio to make all Haskell packages have
# low priority.

let result = let callPackage = x : y : modifyPrio (newScope result.final x y);
                 self = (prefFun result) result; in

  # GHC and its wrapper
  #
  # We use a wrapped version of GHC for nearly everything. The wrapped version
  # adds functionality to GHC to find libraries depended on or installed via
  # Nix. Because the wrapper is so much more useful than the plain GHC, we
  # call the plain GHC ghcPlain and the wrapped GHC simply ghc.
