go_dep_search

golang dependency search tool.

Install

go get -u github.com/ma6174/go_dep_search

or get with graphviz embed

go get -u -tags graphviz github.com/ma6174/go_dep_search

Usage

go list -json -deps -test all | go_dep_search package_names

Args:
  -chain
    	show dep chained
  -main
    	only show main package
  -unused
    	list unused packages

eg: find which command(main package) use net/http or encoding/json package in go source code:

root@b7e158d83ff2:/go# go list -json all | go_dep_search -main net/http encoding/json
main -> cmd/go -> net/http
main -> cmd/pprof -> net/http
main -> cmd/trace -> net/http
main -> cmd/pprof -> encoding/json
main -> cmd/dist -> encoding/json
main -> cmd/go -> encoding/json
main -> cmd/test2json -> encoding/json
main -> cmd/cover -> encoding/json
main -> cmd/trace -> encoding/json
main -> cmd/compile -> encoding/json
main -> cmd/link -> encoding/json
main -> cmd/vet -> encoding/json

eg: show chained package deps

root@b7e158d83ff2:/go# go list -json all | go_dep_search -chain net/http encoding/json
main -> cmd/go -> cmd/go/internal/bug -> cmd/go/internal/envcmd -> cmd/go/internal/modload -> cmd/go/internal/modfetch -> cmd/go/internal/web2 -> net/http
main -> cmd/pprof -> net/http
main -> cmd/trace -> net/http
main -> cmd/compile -> cmd/compile/internal/amd64 -> cmd/compile/internal/gc -> encoding/json
main -> cmd/test2json -> cmd/internal/test2json -> encoding/json
main -> cmd/cover -> encoding/json
main -> cmd/dist -> encoding/json
main -> cmd/go -> cmd/go/internal/envcmd -> encoding/json
main -> cmd/link -> cmd/link/internal/arm64 -> cmd/link/internal/ld -> encoding/json
main -> cmd/pprof -> cmd/vendor/github.com/google/pprof/driver -> cmd/vendor/github.com/google/pprof/internal/driver -> encoding/json
main -> cmd/trace -> encoding/json
main -> cmd/vet -> cmd/vendor/golang.org/x/tools/go/analysis/unitchecker -> encoding/json

eg: show dep graph from net/http to net

root@b7e158d83ff2:/go# go list -json all | go_dep_search -graph -o net.jpg net/http net

result saved to net.jpg

eg: show unsed packages

root@b7e158d83ff2:/go# go list -json all | go_dep_search -unused
