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, ELSE, ENDIF preprocessor branches
  3. IFDEF, IFNDEF preprocessors

As such a script such as this: <lsl>

  1. define DEBUG
  1. ifdef DEBUG

string mode = "DEBUG";

  1. else

string mode = "NORMAL";

  1. endif

default {

  1. ifdef DEBUG
   on_rez(integer s)
   {
       llResetScript()
   }
  1. endif
   state_entry()
   {
       llOwnerSay(mode);
  1. ifdef 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 defined <lsl>

  1. define DEBUG

string mode = "DEBUG";

default {

   on_rez(integer s)
   {
       llResetScript()
   }
   state_entry()
   {
       llOwnerSay(mode);
       llOwnerSay(llGetDate();
   }

} </lsl>

Without DEBUG defined <lsl> string mode = "NORMAL";

default {

   state_entry()
   {
       llOwnerSay(mode);
   }

} </lsl>
