Boringly simple parsing and validation for various notations.

• 🏦 BICs
• 💰 IBANs with country-specific BBAN validation
• 🏴‍☠️ ISO3166-1 Alpha2 (e.g. DE, or ES)
• 🚑 German Health Insurance Numbers (Krankenversicherungsnummern)
• 🧓 German Pension Insurance Numbers (Renten-/ Sozialversicherungsnummern)
• 💲 German Tax Identification Numbers (Steuer-IDs)
• ✉ German Postal Codes (Postleitzahlen)

Each standard is implemented in its own package, and each package provides a type for the standard, e.g. bic.BIC for BICs. That type contains all the information that can be extracted from the notation.

package bic

type BIC struct {
	BusinessPartyPrefix string
	CountryCode         string
	BusinessPartySuffix string
	BranchCode          string
}

Each type implements:

• String() string to get the notation pretty-printed
• Compact() string to get the notation in compact, machine-readable form
• MarshalText() ([]byte, error) same as Compact
• UnmarshalText([]byte) error to parse the notation

Additionally, each package provides these two functions:

• Parse(string) (Type, error) parses the given string, and validates it
• IsValid(string) bool simply checks whether the given string is valid in the given standard.
