Examples

Returns the number of leading and trailing spaces on a string (not particularly useful but shows how to use the function). <lsl> default {

   state_entry()
   {
       llListen(4, "", llGetOwner(), "");
   }
   on_rez(integer a)
   {
       llResetScript();
   }
   listen(integer chan, string name, key id, string msg)
   {
       //test for and remove wrapping single or double quotes
       if(~llSubStringIndex("'\"", llGetSubString(msg,0,0)))
           if(llGetSubString(msg,-1,-1) == llGetSubString(msg,0,0))
               msg = llDeleteSubString(msg, -1, 0);
       
       //track the length
       integer length = llStringLength(msg);
       
       //trim msg (not necessary to store these to variables but makes reading easier)
       string trim_left = llStringTrim(msg, STRING_TRIM_HEAD);
       string trim_right = llStringTrim(msg, STRING_TRIM_HEAD);
       string trim = llStringTrim(msg, STRING_TRIM);

       //output the results
       llOwnerSay("Initial length = " + (string)length +
                "\nLeading Spaces = " + (string)(length - llStringLength(trim_left))+
                "\nTrailing Spaces = " + (string)(length - llStringLength(trim_right))+
                "\nTrimmed Message = \"" + trim + "\"");
   }

}

</lsl>

Notes

The following examples will make the same result. <lsl> string src = " Duh "; st = llStringTrim(src, STRING_TRIM_HEAD); st = llStringTrim(st , STRING_TRIM_TAIL); </lsl> <lsl> string src = " Duh "; st = llStringTrim(src, STRING_TRIM); </lsl>

This is because (STRING_TRIM_HEAD | STRING_TRIM_TAIL) == STRING_TRIM.
