With some playing, I get to this, which gives me what I want for
downstream.
func DocComments(path string) (docs map[string]map[string][]*ast.Comment, err
error) {
fset := token.NewFileSet()
pkgs, err := parser.ParseDir(fset, path, nil, parser.ParseComments)
if err != nil {
return nil, err
}
docs = make(map[string]map[string][]*ast.Comment)
for _, p := range pkgs {
for _, f := range p.Files {
for _, n := range f.Decls {
fn, ok := n.(*ast.FuncDecl)
if !ok || fn.Doc == nil {
continue
}
var typ string
if fn.Recv != nil && len(fn.Recv.List) > 0 {
id, ok :=
fn.Recv.List[0].Type.(*ast.Ident)
if ok {
typ = id.Name
}
}
doc, ok := docs[typ]
if !ok {
doc = make(map[string][]*ast.Comment)
docs[typ] = doc
}
doc[fn.Name.String()] = fn.Doc.List
}
}
}
return docs, nil
}
