gopkggraph

Utility that prints the package graph of Go packages.

Usage

go run github.com/aduong/gopkggraph -help

Print the graph with defaults (as pairs, no filtering):

$ go run github.com/aduong/gopkggraph github.com/aduong/gopkggraph
github.com/aduong/gopkggraph -> errors
github.com/aduong/gopkggraph -> flag
github.com/aduong/gopkggraph -> fmt
github.com/aduong/gopkggraph -> github.com/aduong/gopkggraph/pkg/pkgwalker
github.com/aduong/gopkggraph -> io
github.com/aduong/gopkggraph -> os
github.com/aduong/gopkggraph -> regexp
errors -> internal/reflectlite
flag -> reflect
flag -> sort
flag -> strconv
flag -> strings
flag -> time
...

Print the graph in a tree-like format:

$ go run github.com/aduong/gopkggraph -format treelike github.com/aduong/gopkggraph
github.com/aduong/gopkggraph
├─ errors
├─ flag
├─ fmt
├─ github.com/aduong/gopkggraph/pkg/pkgwalker
├─ io
├─ os
└─ regexp
errors
└─ internal/reflectlite
...

Print the graph as pairs filtering only for your package:

$ go run github.com/aduong/gopkggraph -match github.com/aduong/gopkggraph github.com/aduong/gopkggraph
github.com/aduong/gopkggraph -> github.com/aduong/gopkggraph/pkg/pkgwalker
