Localized Address Formats

KContact's address formatting largely follows the approach taken by libaddressinput, with adding a few additional fields and formatting styles.

Address formatting rules are specified in the addressformatrc file in the src directory, grouped by country. The formatting rules format is compatible with that of libaddressinput.

Address Format Information

• AddressFormat: the default address format using native script, using the placeholders specified below (mandatory).
• LatinAddressFormat: for countries using a non-latin script this can provide an alternative format for addresses transliterated to a latin script (optional).
• BusinessAddressFormat: used for formatting postal addresses of an organization. This only needs to be specified if the format differs from the generic case.
• LatinBusinessAddressFormat: see LatinAddressFormat.

All of the above values may be specified in multiple variants for multi-lingual countries. This is typically only needed when the format rule contains literal strings, e.g. for specifying a post office box.

• Required: The address fields that are minimally required to form a valid address in this country.
• Upper: The address fields to be formatted in upper case regardless of the input for postal addresses.

The above values are specified as a string containing the single letter address field identifiers listed below. E.g. "AZC" would indicate that a street address, postal code and locality (city) are required.

• PostalCodeFormat: A regular expression matching all valid postal codes in this country.

Address Field Identifiers

The following identifiers are used in the formatting rules to refer to specific parts of an address:

• N - Name of a person/Recipient of a letter
• O - Organization
• A – Street address
• C – Locality (city)
• S – Region (country subdivision/administrative area/state/etc)
• Z – Postal code/zip code
• R - Country

Identifiers used by libaddressinput but not by KContacts:

• D – Dependent locality (may be an inner-city district or a suburb)
• X – Sorting code

Address Formatting Rules

Address formatting rules consist of a sequence of elements of the following three types:

• Fields - Insert the value of the corresponding address field, specified as a % sign followed by a field identifier (see above).
• Separators - Represented as n. Depending on the formatting style those are replaced e.g. a line break or a script-dependent separator string.
• Literals - Any other string. Inserted as-is in the output, given it is neither preceded nor followed by an empty field.
