pkgrank

Discover important Go package dependencies with graph centrality scores on the package import DAG.

Example usage:

$ go get -u github.com/henrywallace/pkgrank
$ pkgrank crypto/...

Use --prefix to filter package imports with the given prefix, or --pkg to iterate over imports by package, instead of by file.

Current implementation is naive by calling out to go list subprocesses. And currently only pagerank centrality is implemented. Nodes are packages, and edges are directed graph of A >- imports -> B. Edge weights are the number of times that package A imports package B, which may be multiple if files are iterated over instead of packages with --pkg.
