fmt.Printf("// %s: %s\n", pkg, pkg.Doc)

vars := pkg.Vars()
for _, v := range vars {
  fmt.Printf("var %v %v\n", v.Name(), v.Type())

Package srcutil provides utilities for working with Go source code. The Go standard library provides a powerful suite of packages "go/{ast,doc,...}" which are used by the Go tool chain to compile Go programs. As you initially try to find your way around you hit a small dependency barrier and have to learn a small portion of each package. There is a fantastic write up and collection of examples that I used to learn (or shamelessly copy pasta'd) while creating this package, currently maintained by:

  Alan Donovan (https://github.com/golang/example/tree/master/gotypes)

In the mean time this package can help you get started with some common use cases.
