Nice little function to split by slashes while ignoring slashes inside quotes (e.g. /Invoices/"Invoice (9/1)"/invoice.txt)

split-by-slash.go

func splitBySlash(s string) []string {
	lastQuote := rune(0)
	slash := rune(filepath.Separator)

	f := func(c rune) bool {
		switch {
		case c == lastQuote:
			lastQuote = rune(0)
			return false
		case lastQuote != rune(0):
			return false
		case unicode.In(c, unicode.Quotation_Mark):
			lastQuote = c
			return false
		default:
			return c == slash
		}
	}
	return strings.FieldsFunc(s, f)
}
