String Compare

String compare

Created by Xaviar Czervik. Do whatever you wish with this function: Sell it (good luck), use it, or modify it.

The following code returns 1, -1 or 0. The 1 and -1 are essentially random, however it will return the same value every time the script is executed. 0 Is returned when, and only when, the strings are exactly equal. Completely re-designed to use a few tricks I learned in the past months. Also much easier to read now.

I have used this script for comparing the Keys of two objects in a dynamic set of sensors, to decide which one should be the "Master" in the region to tell me information. I'm sure there can be more uses to this...

<lsl> integer compare(string s1, string s2) {

   if (s1 == s2) {
       return 0;
   } else if (llStringLength(s1) < llStringLength(s2)) {
       return 1;
   } else if (llStringLength(s1) > llStringLength(s2)) {
       return -1;
   } else {
       list l = [s1, s2];
       l = llListSort(l, 0, 1);
       if (s1 == llList2String(l, 0))
           return 1;
       return -1;
   }

} </lsl>
