Synopsis

Documentation

data ConfiguredComponent Source #

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

Constructors

ConfiguredComponent

Fields

cc_cid :: ComponentId
Uniquely identifies a configured component.
cc_pkgid :: PackageId
The package this component came from.
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_internal_build_tools :: [ComponentId]
Dependencies on internal executables from build-tools.
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 Source #

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

toConfiguredComponent :: PackageDescription -> ComponentId -> Map PackageName (ComponentId, PackageId) -> ConfiguredComponentMap -> Component -> ConfiguredComponent Source #

Given some ambient environment of package names that are "in scope", looks at the BuildInfo to decide what the packages actually resolve to, and then builds a ConfiguredComponent.

toConfiguredComponents :: Bool -> FlagAssignment -> Bool -> Flag String -> Flag ComponentId -> PackageDescription -> Map PackageName (ComponentId, PackageId) -> [Component] -> [ConfiguredComponent] Source #

dispConfiguredComponent :: ConfiguredComponent -> Doc Source #

Pretty-print a ConfiguredComponent.

type ConfiguredComponentMap = (Map PackageName (ComponentId, PackageId), Map UnqualComponentName ComponentId) Source #

extendConfiguredComponentMap :: ConfiguredComponent -> ConfiguredComponentMap -> ConfiguredComponentMap Source #

newPackageDepsBehaviour :: PackageDescription -> Bool Source #
