Expanding consoleFunctions - isWordInSet?

In my current project I need a lot of checking if a special word exists in some string (words set).
e.g. - I have a string with values : "one two seven ten"
I need to check if word "four" is in.
How do I do it?
Yes, I can make a for() loop and use getWord() and do comparision. But when server doing it a lot, it takes some processor time parsing a script, so here is a C++ code of this function. This can be as example of HOWTO expanding Torque.
Open engine/console/consoleFunctions.cc and in a group of ConsoleFunctionGroupBegin( FieldManipulators... add the following:

ConsoleFunction(isWordInSet, bool, 3, 3, "(string text, string word)")
{
   U32 units = getUnitCount(argv[1], " \t\n");
   for (U32 inc=0;inc<units;inc++)
      if (dStricmp(getUnit(argv[1], inc, " \t\n"),argv[2])==0)
         return true;
   return false;
}

The use of it is simple:

%text = "one two seven ten";
%word = "four";
if (isWordInSet(%text, %word)) {
   warn(%word SPC "is NOT in set" SPC %text);
} else {
   echo(%word SPC "is in" SPC %text);
}

I've just moved the whole manipulation from script to c++ code for making engine to work faster. It's a moments of saved time, but in total you can win a lot.
Will you find this useful or not - it's up to you.
