openlocationcode

Convert locations to and from convenient short codes.

Open Location Codes are short, ~10 character codes that can be used instead of street addresses. The codes can be generated and decoded offline, and use a reduced character set that minimises the chance of codes including words.

Ported from the Java interface.

Classes

OLCFormatException class OLCFormatException: Thrown in methods validating a user input string code.

Functions

isFullCode bool isFullCode(string code): Returns if the code is a valid full Open Location Code.
isFullUppercaseCode bool isFullUppercaseCode(string code): Does the same as isFullCode, assuming the code is already uppercase, making this @nogc nothrow.
isShortCode bool isShortCode(string code): Returns if the code is a valid short Open Location Code.
isShortUppercaseCode bool isShortUppercaseCode(string code): Does the same as isShortCode, assuming the code is already uppercase, making this @nogc nothrow.
isValidCode bool isValidCode(string codeString): Returns whether the provided string is a valid Open Location code.
isValidCodeLength bool isValidCodeLength(int codeLength): Returns whether the provided code length
isValidUppercaseCode bool isValidUppercaseCode(string codeString): Same as isValidCode but doesn't convert the code to uppercase before handling, thus failing validation when using lowercase characters.

Manifest constants

codePrecisionNormal enum codePrecisionNormal;: Provides a normal precision code, approximately 14x14 meters.
maxDigitCount enum maxDigitCount;: The max number of digits to process in a plus code.
maxOLCLength enum maxOLCLength;: The max number of characters in an open location code. This is the max number of digits plus a separator character.
paddingCharacter enum paddingCharacter;: The character used to pad codes.
separator enum separator;: A separator used to break the code into two parts to aid memorability.

Static variables

codeAlphabet ubyte[] codeAlphabet;: The character set used to encode the values.

Structs
