- string listClean(stringList)
Returns cleaned stringList.
The listClean function checks if the stringList has the correct ";" at the end. Additionally, empty items (';;') are removed.
Stringlists are a series of strings stored inside one string. The elements are separated by a semicolon (";"). Each item must be followed by a semicolon, also the last one! The data type is "string", thus it is not an array as used in other scripting languages.
listClean(";;;;;my;city;rules;;your;;city;;") # result = "my;city;rules;your;city;"
listClean(";;cityengine;;;rules") # result = "cityengine;rules;"
