type Graph ¶
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 Build ¶
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/".
