type ComponentsGraph = [(Component, [ComponentName])] Source #
A components graph is a source level graph tracking the dependencies between components in a package.
dispComponentsGraph :: ComponentsGraph -> Doc Source #
Pretty-print a ComponentsGraph.
toComponentsGraph :: ComponentRequestedSpec -> PackageDescription -> Either [ComponentName] ComponentsGraph Source #
Given the package description and a PackageDescription (used
to determine if a package name is internal or not), create a graph of
dependencies between the components. This is NOT necessarily the
build order (although it is in the absence of Backpack.)
componentCycleMsg :: [ComponentName] -> Doc Source #
Error message when there is a cycle; takes the SCC of components.
