Stack.Types.CompCollection

A module providing the type CompCollection and associated helper functions.

The corresponding Cabal approach uses lists. See, for example, the sublibraries, foreignLibs, executables, testSuites, and benchmarks fields.

Cabal removes all the unbuildable components very early (at the cost of slightly worse error messages).

getBuildableSet :: CompCollection component -> Set StackUnqualCompName

Get the names of the buildable components in the given collection, as a Set of StackUnqualCompName.

getBuildableSetText :: CompCollection component -> Set Text

Get the names of the buildable components in the given collection, as a Set of Text.

getBuildableListText :: CompCollection component -> [Text]

Get the names of the buildable components in the given collection, as a list of 'Text.

getBuildableListAs

Arguments

:: (StackUnqualCompName -> something)

Function to apply to buildable components.

-> CompCollection component

Collection of components.

-> [something]

Apply the given function to the names of the buildable components in the given collection, yielding a list.

foldAndMakeCollection

Arguments

:: (HasBuildInfo compB, HasName compB, Foldable sourceCollection)

=> (compA -> compB)

Function to apply to each element in the data struture.

-> sourceCollection compA

Given foldable data structure of components of type compA.

-> CompCollection compB

For the given function and foldable data structure of components of type compA, iterates on the elements of that structure and maps each element to a component of type compB while building a CompCollection.

hasBuildableComponent :: CompCollection component -> Bool

Yields True if, and only if, the given collection includes at least one buildable component.

collectionLookup

Arguments

:: Text

Name of the buildable component.

-> CompCollection component

Collection of components.

-> Maybe component

For the given name of a buildable component and the given collection of components, yields Just component if the collection includes a buildable component of that name, and Nothing otherwise.

collectionKeyValueList :: CompCollection component -> [(Text, component)]

For a given collection of components, yields a list of pairs for buildable components of the name of the component and the component.

collectionMember

Arguments

:: Text

Name of the buildable component.

-> CompCollection component

Collection of components.

-> Bool

Yields True if, and only if, the given collection of components includes a buildable component with the given name.

foldComponentToAnotherCollection

Arguments

:: Monad m

=> CompCollection component

Collection of components.

-> (component -> m a -> m a)

Binary operator.

-> m a

Starting value.

-> m a

Reduce the buildable components of the given collection of components by applying the given binary operator to all buildable components, using the given starting value (typically the right-identity of the operator).
