pkg/mocai/entities/national_id/generator.go (2)
5-7: Struct design looks good but consider future extensibility.The
NationalIDstruct is well-designed for the current implementation with Brazilian RG support. However, as new national IDs from other countries are added in the future, you might need to refactor this structure.Consider whether you'll want to structure this more generically in the future, perhaps with a country-agnostic interface or a type field to identify which country's ID is being used.
9-11: Documentation is clear but could mention Brazil-specific scope.The documentation clearly explains the formatting options, but it could be more explicit that this currently only supports Brazilian IDs.
-// GenerateNationalID generates a Brazilian national ID [RG]. +// GenerateNationalID generates a national ID, currently supporting only Brazilian RG.pkg/mocai/entities/national_id/countries/errors.go (1)
8-8: Error message could be more specific.The error message for
ErrToConvertDigitis a bit vague.- ErrToConvertDigit = errors.New("error converting digit") + ErrToConvertDigit = errors.New("error converting RG digit from string to integer")examples/mock_example.go (1)
55-59: Error handling inconsistency.The error handling for the national ID generation doesn't follow the same pattern as the other error handling blocks in this file which include a return statement.
nationalID_mock, err := national_id.GenerateNationalID(false) if err != nil { fmt.Print(err) + return }pkg/mocai/entities/national_id/countries/brazilian_national_id.go (4)
18-32: Function implementation is correct but state-specific.The function correctly implements the Brazilian national ID generation, but it's specifically for São Paulo (SP). This could be made clearer in the documentation.
-// GenerateBrazilianNationalID generates a valid Brazilian national ID [RG] for São Paulo. +// GenerateBrazilianNationalID generates a valid Brazilian national ID [RG]. +// Currently, only São Paulo (SP) state IDs are supported.
34-38: Missing validation for base number length.The function generates a random base number but doesn't validate that it doesn't exceed 8 digits, despite having an error defined for this case (
ErrBaseNumberExceedsLimit).// calculateSPRGDigit generates a valid Brazilian national ID [RG] for São Paulo. func calculateSPRGDigit() (string, error) { // generate a random base until 8 digits base := globalRand.Intn(100000000) baseStr := fmt.Sprintf("%08d", base) + + if len(baseStr) > 8 { + return "", ErrBaseNumberExceedsLimit + }
41-48: Inefficient array initialization.Creating a fixed-size array and populating it in a loop is less efficient and clear than using a slice literal or more direct conversion.
- // slice contains the digits - d := make([]int, 8) - for i := range 8 { - val, err := strconv.Atoi(string(baseStr[i])) - if err != nil { - return "", ErrToConvertDigit - } - d[i] = val - } + // slice contains the digits + d := make([]int, 8) + for i, r := range baseStr { + val, err := strconv.Atoi(string(r)) + if err != nil { + return "", ErrToConvertDigit + } + d[i] = val + }
51-51: Typo in variable name.The variable is named "wheights" when it should be "weights".
- // wheights from right to left: 9, 8, 7, 6, 5, 4, 3, 2 - wheights := []int{2, 3, 4, 5, 6, 7, 8, 9} + // weights from right to left: 9, 8, 7, 6, 5, 4, 3, 2 + weights := []int{2, 3, 4, 5, 6, 7, 8, 9}And then update the reference in the calculation:
for i := 0; i < 8; i++ { - sum += d[7-i] * wheights[i] + sum += d[7-i] * weights[i] }

Security risk with math/rand for ID generation.
Using math/rand for generating identity documents is not secure enough as it's predictable. For security-sensitive data like national IDs, crypto/rand should be used instead.

there’s no need since the data is made up

@wellfernandes You're right. Since this is just for generating mock data and not real IDs, using math/rand is perfectly fine. No need for the cryptographically secure alternative in this case.

Learning: For the mocai project, using math/rand is acceptable for generating mock data (like national IDs) since the data is fictitious and not intended for security-sensitive purposes.

Improve validation in formatRG function.
The function only checks if the length is not equal to 9, but doesn't handle cases where it's less than 9, which could cause a panic with the slicing operations.
func formatRG(input string) string {
- if len(input) != 9 {
+ if len(input) < 9 {
return input
}📝 Committable suggestion

its not the best option as it doesn’t cover all cases

@wellfernandes You're absolutely right. Looking at the full function:
func formatRG(input string) string {
if len(input) != 9 {
return input
}
return fmt.Sprintf("%s.%s.%s-%s", input[0:3], input[3:6], input[6:8], input[8:])
}The original check len(input) != 9 is better as it handles both cases:
- Inputs shorter than 9 characters (preventing slice panics)
- Inputs longer than 9 characters (preventing incorrect formatting)
My suggested change would incorrectly attempt to format inputs that are too long. The current implementation is already optimal for handling all edge cases.

Learning: In the Brazilian RG (national ID) formatter, the check for `len(input) != 9` is intentional as it handles both cases where input is too short (preventing panics) and too long (preventing incorrect formatting).

34-35: Incorrect function comment for calculateSPRGDigit.The function comment appears to be copied from
GenerateBrazilianNationalIDand doesn't accurately describe this function's specific purpose.-// calculateSPRGDigit generates a valid Brazilian national ID [RG] for São Paulo. +// calculateSPRGDigit generates a random base number and calculates the check digit +// for a São Paulo RG (Registro Geral) document.
41-48: Digit extraction loop could be simplified.The current implementation creates a slice and loops through the string to convert each character to an integer. This could be more concise.
- // slice contains the digits - d := make([]int, 8) - for i := range 8 { - val, err := strconv.Atoi(string(baseStr[i])) - if err != nil { - return "", ErrToConvertDigit - } - d[i] = val - } + // slice contains the digits + d := make([]int, 8) + for i, char := range baseStr { + val, err := strconv.Atoi(string(char)) + if err != nil { + return "", ErrToConvertDigit + } + d[i] = val + }
50-51: Typo in variable name.There's a spelling error in the variable name "wheights".
- // wheights from right to left: 9, 8, 7, 6, 5, 4, 3, 2 - wheights := []int{2, 3, 4, 5, 6, 7, 8, 9} + // weights from right to left: 9, 8, 7, 6, 5, 4, 3, 2 + weights := []int{2, 3, 4, 5, 6, 7, 8, 9}Don't forget to update the reference in the calculation part as well:
- sum += d[7-i] * wheights[i] + sum += d[7-i] * weights[i]

4-10: Import and global rand setup looks good.The use of
math/randis appropriate for generating mock data as confirmed in previous discussions. The global random number generator is properly initialized with the current time as seed.
12-16: RG struct design is clean and appropriate.The struct contains all necessary fields for a Brazilian national ID: Number, State, and IssuingBody.
18-32: GenerateBrazilianNationalID function implementation is well-structured.The function properly handles error cases and conditionally formats the RG number. The returned struct contains all required information.
72-77: The formatRG function validation is appropriate.The check for
len(rgNumber) != 9correctly handles both cases where input is too short (preventing panics) and too long (preventing incorrect formatting).
