List_cast

List_cast

Summary

Function: list List_cast( list in );

Iterates through the contents of a list, producing a resulting list whose contents are cast from strings to their identified type. This function is useful for converting a list of strings, such as from llParseString2List, to a list that could be used for llSetPrimitiveParams, or a list you know you are going to use a lot to save on casting all the time.
Returns a list whose contents are cast to their identified types.

• list

in

–

The list to cast, its contents should be all strings.

Caveats

• Any strings fed into this function (which are meant to stay strings) cannot contain pointed brackets (<>) They will be cast as vectors or rotations, if they do.

Examples

<lsl>

       list in = ["1", "<1.0,2.5,0.5>", "0.8", "0", "Four", "8aef4875-6873-0919-f5ab-c9d6b48d18d4"];

       in = list_cast(in);
       llSetScale( llList2Vector(in,1) );
       llSetAlpha( llList2Float(in,2), llList2Integer(in,3) );

</lsl>

Implementation

<lsl> //This function typecasts a list of strings, into the types they appear to be. //Extremely useful for feeding user data into llSetPrimitiveParams //It takes a list as an input, and returns that list, with all elements correctly typecast, as output //Written by Fractured Crystal, 27 Jan 2010, Commissioned by WarKirby Magojiro, this function is Public Domain list list_cast(list in) {

   list out;
   integer i = 0;
   integer l= llGetListLength(in);
   while(i < l)
   {
       string d= llStringTrim(llList2String(in,i),STRING_TRIM);
       if(d == "")out += "";
       else
       {
           if(llGetSubString(d,0,0) == "<")
           {
               if(llGetSubString(d,-1,-1) == ">")
               {
                   list s = llParseString2List(d,[","],[]);
                   integer sl= llGetListLength(s);
                   if(sl == 3)

               //either malformed,or identified
               jump end;
           }
           if(llSubStringIndex(d,".") != -1)
           {

               if((string)lold == d)out += lold;
               else
               {
                   key kold = (key)d;
                   if(kold)out += [kold];
