import (

type justFilesFilesystem struct {
  fs http.FileSystem
}

func (fs justFilesFilesystem) Open(name string) (http.File, error) {
  f, err := fs.fs.Open(name)
  if err != nil {
      return nil, err
  }
  return neuteredReaddirFile{f}, nil
}

type neuteredReaddirFile struct {
  http.File
}

func (f neuteredReaddirFile) Readdir(count int) ([]os.FileInfo, error) {
  return nil, nil
}

func main() {
  fs := justFilesFilesystem{http.Dir("/tmp/")}
  http.ListenAndServe(":8080", http.FileServer(fs))
}
