Function: list ListXorY(list lx, list ly);

Join two lists to make one new combined list, while also eliminating any resulting duplicates in the new list.

See also: Lists

list ListXorY(list lx, list ly){ // add the lists eliminating duplicates
    list lz = []; integer x;
    for (x = 0; x < llGetListLength(ly); ++x){
        if (~llListFindList(lx,llList2List(ly,x,x))){
            ;
        }
        else {
            lz = lz + llList2List(ly,x,x);
        }
    }
    return lx + lz;
}


Example:

list l1 = ["a","b","c","d"];
list l2 = ["a","1","b","2","c","3"];

list ListXorY(list lx, list ly){ // add the lists eliminating duplicates
    list lz = []; integer x;
    for (x = 0; x < llGetListLength(ly); ++x){
        if (~llListFindList(lx,llList2List(ly,x,x))){
            ;
        }
        else {
            lz = lz + llList2List(ly,x,x);
        }
    }
    return lx + lz;
}

default{
   state_entry() {
      llSay(0, "The new combined list is: " + llList2CSV(ListXorY(l1,l2)) );
      //will say: a, b, c, d, 1, 2, 3
   }
}
