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.
