Package importgraph computes the forward and reverse import dependency graphs for all packages in a Go workspace.

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/".

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.

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.
