Documentation
type ComponentsGraph = Graph (Node ComponentName Component) Source #
A graph of source-level components by their source-level dependencies
type ComponentsWithDeps = [(Component, [ComponentName])] Source #
A list of components associated with the source level dependencies between them.
mkComponentsGraph :: ComponentRequestedSpec -> PackageDescription -> Either [ComponentName] ComponentsGraph Source #
Create a Graph of Component, or report a cycle if there is a
problem.
componentsGraphToList :: ComponentsGraph -> ComponentsWithDeps Source #
Given the package description and a PackageDescription (used
to determine if a package name is internal or not), sort the
components in dependency order (fewest dependencies first). This is
NOT necessarily the build order (although it is in the absence of
Backpack.)
dispComponentsWithDeps :: ComponentsWithDeps -> Doc Source #
Pretty-print ComponentsWithDeps.
componentCycleMsg :: PackageIdentifier -> [ComponentName] -> Doc Source #
Error message when there is a cycle; takes the SCC of components.
