Ugh, first of all, you should try asking this in rec.games.programmer
and also search on dejanews about scripting languages, I started a
couple of threads on this too. I'm also interested in this, but I don't
have much info. What I can tell you is you should use Flex combined with
Bison for the parser (Flex lexes the source returning tokens while Bison
interprets those tokens;together they make your parser) and then
transform this into a binary tree.
You transform the source into bytecode (like pseudo-assembly
instructions) and you have a virtual machine interpreting the bytecode.
Your script has a stack and instruction pointer etc working a lot like a
CPU. You should go to www.gamasutra.com in the programming section.
There is an article on COG, the scripting language used in Jedi Knight.
I hope this helps a bit.
