Okay, so I have a problem.
I'm build a special kind of preprocessor. It'll look over a source file for specific keywords, and if it finds those keywords, insert strings based on those keywords (and everything else following that single line), and such.
Since this is almost impossible to explain without an example, I'll throw one at you.
Look at this source code:
Will get compiled into this:
Things like the "globals" block will be merged with an already existing "globals" block (there is only one, at the start of the file).
My problem is finding out how to do all this (and much, much more).
But wait! That's not my only problem! My other problem is how to do it efficiently.
Speed of the preprocessor, and of the generated code (which is all me. I don't need help on that one.
) is the main priority. If it's not fast, people aren't going to use it, which is bad.
So my questions are:
1. How can I look for specific keywords, and if I find them, output results into a file in specific blocks?
2. How can I optimize this so it can compile several thousand lines under 30 (preferably 20) seconds?
3. How can I do all this, and still get full cross compatibility over Mac, Linux, and Windows?
Thanks for any help.

. I can work on a script for you, is this what you want?:
