The range of multiple nonempty values.
assert(equal(IconThemeFile.splitValues("16x16/actions,16x16/animations,16x16/apps"), ["16x16/actions", "16x16/animations", "16x16/apps"])); assert(IconThemeFile.splitValues(",").empty); assert(IconThemeFile.splitValues("").empty);
Some keys can have multiple values, separated by comma. This function helps to parse such kind of strings into the range.
