I want to add a little function to the C preprocessor, but for this I need one that is easy to understand and can be easily changed. In particular, I am looking for the following criteria:
- small code
- well documented
- easy to change
- free software (I want to be able to distribute the modified code without paying fees or so).
I already found a tcc that includes a preprocessor and is pretty small, but as far as I can see, there is no good documentation on how preprocessing is done, Should I just try to figure out how this is possible or better?
