示例1: StringToValue

// StringToValue takes a piece of data as a string and attempts to convert it to a types.Value of the appropriate types.NomsKind.
func StringToValue(s string, k types.NomsKind) (types.Value, error) {
	switch k {
	case types.NumberKind:
		if s == "" {
			return types.Number(float64(0)), nil
		}
		fval, err := strconv.ParseFloat(s, 64)
		if err != nil {
			return nil, fmt.Errorf("Could not parse '%s' into number (%s)", s, err)
		}
		return types.Number(fval), nil
	case types.BoolKind:
		// TODO: This should probably be configurable.
		switch s {
