Preprocessing

I suggest the ability to add preprocessing to LSL, as this has no effect on LSL itself but can provide scripts which can do many different things, depending on.

This would include.

1. Basic Define keyword, can be used to define custom static variables. (these may need to be typed)
2. IF, IFN, ELSE, ENDIF preprocessor branches

As such a script such as this: <lsl>

1. define DEBUG TRUE

1. if DEBUG

string mode = "DEBUG";

1. else

string mode = "NORMAL";

1. endif

default {

1. if DEBUG

   on_rez(integer s)
   {
       llResetScript()
   }

1. endif

   state_entry()
   {
       llOwnerSay(mode);

1. if DEBUG

       llOwnerSay(llGetDate();
   }

1. else

   }

1. endif

} </lsl>

Could produce two different scripts depending on the value of DEBUG, which would then get compiled/interpreted.

With DEBUG set to TRUE. <lsl>

1. define DEBUG TRUE

string mode = "DEBUG";

default {

   on_rez(integer s)
   {
       llResetScript()
   }

   state_entry()
   {
       llOwnerSay(mode);
       llOwnerSay(llGetDate();
   }

} </lsl>

With DEBUG set to FALSE. <lsl>

1. define DEBUG FALSE

string mode = "NORMAL";

default {

   state_entry()
   {
       llOwnerSay(mode);
   }

} </lsl>
