func Build Uses

func Build(ctxt *build.Context) (forward, reverse Graph, errors map[string]error)

Build scans the specified Go workspace and builds the forward and reverse import dependency graphs for all its packages. It also returns a mapping from canonical import paths to errors for packages whose loading was not entirely successful. A package may appear in the graph and in the errors mapping. All package paths are canonical and may contain "/vendor/".

type Graph Uses

type Graph map[string]map[string]bool

A Graph is an import dependency graph, either forward or reverse.

The graph maps each node (a package import path) to the set of its successors in the graph. For a forward graph, this is the set of imported packages (prerequisites); for a reverse graph, it is the set of importing packages (clients).

Graph construction inspects all imports in each package's directory, including those in _test.go files, so the resulting graph may be cyclic.

func (Graph) Search Uses

func (g Graph) Search(roots ...string) map[string]bool

Search returns all the nodes of the graph reachable from any of the specified roots, by following edges forwards. Relationally, this is the reflexive transitive closure.

Package importgraph imports 3 packages (graph) and is imported by 16 packages. Updated 2017-10-14. Refresh now. Tools for package owners.
