Configuration

Fields

• compilerInfo :: CompilerInfo

  Target compiler. Used by finalizePackageDescription to choose appropriate flags and dependencies.

• corePackages :: Set PackageIdentifier

  Compiler core packages that are also found on Hackage.

• defaultPackageOverrides :: [Constraint]

  These packages replace the latest respective version during dependency resolution.

• extraPackages :: [Constraint]

  These packages are added to the generated set, but the play no role during dependency resolution.

• dontDistributePackages :: Map PackageName (Set Platform)

  We know that these packages won't build, so we give them an empty meta.hydraPlatforms attribute to avoid cluttering our Hydra output with lots of failure messages.

• packageMaintainers :: Map Identifier (Set PackageName)

  This information is used by the hackage2nix utility to determine the maintainers for a given Haskell package.
