About Me

I am a generalist. I was once a systems engineer and the head of an IT department.

Boredom comes easily to me.

Every now and again I build a website for someone; I do not have my own.

I like SecondLife.

XXTEA Cipher

This is something I decided to do for no good reason. It probably isn't optimal, and it probably needs work, but it works. At some point it might want to be integrated into the XTEA page, or get its own page. Feel free to comment on my Talk Page

Code references used:


Note: I can not take any real credit for this work. I just made the pre-existing code function in LSL.

<lsl> 

 // Code coming later...

</lsl>

Datatype Tests

Here are some quick and dirty datatype tests.. so far they work for me. They have not been optimized.

isInteger

<lsl> integer isInteger(string s) { 

   if (s != "") {
       integer i;
       integer l = llStringLength(s);
       do {
           if(! ~llListFindList(["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"], (list)llGetSubString(s, i, i))) return FALSE;
           ++i;
       } while (i < l);
   }
   return TRUE;

} </lsl>

isFloat

<lsl> integer isFloat(string s) { 

   if (s != "") {
       integer i; integer d; string c;
       integer l = llStringLength(s);
       do {
           c = llGetSubString(s, i, i);
           if (! ~llListFindList([".", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"], (list)c)) return FALSE;
           if (c == ".") ++d;
           if (d > 1) return FALSE;
           ++i;
       } while (i < l);
       return TRUE;
   }
   return FALSE;

} </lsl>

isVector

Note: Uses 'isFloat' above . . . <lsl> integer isVector(string s) { 

   list f;
   integer i = 0;
   if ((rotation)s) return FALSE; // don't accept rotations
   if ((vector)s) return TRUE;    // accept any positive valid
   // Everything past here is mostly for testing for a proper ZERO vector, so possibly excessive.
   if (llSubStringIndex(s, "<") == 0)
       if (llSubStringIndex(s, ">") == (llStringLength(s) - 1))
           if (llGetListLength(f = llParseString2List(s, ["<",">", " "], [","])) == 5)
               if (isFloat(llList2String(f, 0)))
                   if (llList2String(f, 1) == ",")
                       if (isFloat(llList2String(f, 0)))
                           if (llList2String(f, 3) == ",")
                               if (isFloat(llList2String(f, 4))) return TRUE;
   return FALSE;

} </lsl>

Client Library Changes

These are the changes to the SL client libraries since 1.13.1.12. I don't expect this to be perfect, nor presented in the best possible way. This is mostly intended for me so that I don't loose this data. If this helps you in some way, and you have suggestions on how to make it better, please feel free to do so on my Talk Page

The emerging patterns are already becoming clear, and I can see that I will be able to reduce the changes down to named library changes instead of listing any files.
