This library is able to divide (German) a concatenated street names consisting of the pure street name, the house number, and its affix into its single parts.
Some streets contain a number as suffix or infix themselves so that it is impossible to decide whether this number is a house number or belongs to the street name. An example is "Straße 101" in Berlin. At first glance this seems to be a street "Straße" with house number "101", but in reality the number "101" is part of the street name. To make this decision unambiguous the street "Straße 101" is added to a list of "special streets". This list can be found in the file "specialstreets.txt" and can/must be updated periodically.
More Examples:
| input | street | house no | affix |
|---|---|---|---|
| Gartenstr. 25a | Gartenstr. | 25 | a |
| Brückenstr. 12a-13c | Brückenstr. | 12 | a-13c |
| Straße 101 Nr. 12 | Straße 101 | 12 | |
| C 3 54 | C 3 | 54 | |
| In den 30 Morgen 34b | In den 30 Morgen | 34 | b |
In the examples above you can see the very strange street names of the city Manheim. The inner of the city in organized as a matrix with names like A4 or C3.
Usage
val streetDivider = StreetDivider()
println(streetDivider.parse("Gartenstr. 25a"))
-> Location(street=Gartenstr., houseNumber=25, houseNoAffix=a)

You can download (downloads/streetdivider.jar) a small executable jar with UI and test the street decomposition with your own street names...
