Two methods of traverse directory with golang

.go

func exclude(dir, path string) bool {

		if info.IsDir() {
			return nil
		}
		if exclude(dir, path) {
			return nil

		list = append(list, path)
		return nil
	})
	return list
}

func readDirAll(dir string) []string {
	list := make([]string, 0)

	var f func(string, string)
