Localization

The validator supports multiple languages for error messages.

You can define your own translations by implementing a custom message mapper in your project.

If you'd like to add a new localization, feel free to open an issue, submit a pull request, or contact the author.

Example:

ValidatorErrComment.messages[Language.FR] = {
    "missing_column": "Colonne manquante: {column}"
}
