data ConfiguredComponent

A configured component, we know exactly what its ComponentId is, and the ComponentIds of the things it depends on.

Constructors

ConfiguredComponent

Fields

• cc_ann_id :: AnnotatedId ComponentId

  Unique identifier of component, plus extra useful info.

• cc_component :: Component

  The fragment of syntax from the Cabal file describing this component.

• cc_public :: Bool

  Is this the public library component of the package? (If we invoke Setup with an instantiation, this is the component the instantiation applies to.) Note that in one-component configure mode, this is always True, because any component is the "public" one.)

• cc_exe_deps :: [AnnotatedId ComponentId]

  Dependencies on executables from build-tools and build-tool-depends.

• cc_includes :: [ComponentInclude ComponentId IncludeRenaming]

  The mixins of this package, including both explicit (from the mixins field) and implicit (from build-depends). Not mix-in linked yet; component configuration only looks at ComponentIds.

cc_name :: ConfiguredComponent -> ComponentName

The ComponentName of a component; this uniquely identifies a fragment of syntax within a specified Cabal file describing the component.

cc_cid :: ConfiguredComponent -> ComponentId

Uniquely identifies a configured component.

cc_pkgid :: ConfiguredComponent -> PackageId

The package this component came from.

toConfiguredComponent :: PackageDescription -> ComponentId -> ConfiguredComponentMap -> ConfiguredComponentMap -> Component -> LogProgress ConfiguredComponent

toConfiguredComponents :: Bool -> FlagAssignment -> Bool -> Flag String -> Flag ComponentId -> PackageDescription -> ConfiguredComponentMap -> [Component] -> LogProgress [ConfiguredComponent]

dispConfiguredComponent :: ConfiguredComponent -> Doc

Pretty-print a ConfiguredComponent.

type ConfiguredComponentMap = Map PackageName (Map ComponentName (AnnotatedId ComponentId))

extendConfiguredComponentMap :: ConfiguredComponent -> ConfiguredComponentMap -> ConfiguredComponentMap

newPackageDepsBehaviour :: PackageDescription -> Bool
