Is there a nicer way to do this than what I have here?
func MethodDocComments(path string) (map[string]string, error) {
fset := token.NewFileSet()
pkgs, err := parser.ParseDir(fset, path, nil, parser.ParseComments)
if err != nil {
return nil, err
}
docs := make(map[string]string)
for _, p := range pkgs {
for _, t := range doc.New(p, path,
doc.AllDecls|doc.AllMethods).Types {
for _, f := range t.Methods {
d := fmt.Sprint("// ", strings.Replace(f.Doc,
"\n", "\n// ", -1))
docs[f.Name] = strings.TrimSuffix(d, "// ")
}
}
}
return docs, nil
}
Ideally, I'd like to just crib the comments directly from the source,
but I don't see an easy way to do that via the AST, but the string
munging above just feels wrong.
