I'll use a concrete example. Substitute with your own.
GOPACKAGE=github.com/mkideal/cli
{ echo "digraph G {"; go list -f '{{ range .Imports }}{{printf "\t%q ->
%q;\n" $.ImportPath .}}{{end}}' $(go list -f '{{join .Deps " "}}'
$GOPACKAGE) $GOPACKAGE | grep '/.*" -> ".*/'; echo "}"; } | dot -Tsvg
-o /tmp/cli.svg
BTW,
instead of piping the result to dot, I redirect it to /tmp/go.dot, then
quickly view it with `dotty /tmp/go.dot`.
