We had a similar discussion already. This involves some kind of re-evaluation of some of the input sequence after changing the internal state of the preprocessor. Wave currently does not support this.
I see, this is really bad then...
Wouldn't this involve making copies of the internal state essentially after every token (or at least before every pp operation), just to ensure it can be restarted at arbitrary points?
Yes, I think it would be needed. But, it should be faster than reprocess everything from the beginning if it spans to many options.
I'm sure its impossible to make sure not to run into inconsistencies when trying to implement such a scheme (even putting aside the possible performance implications of making state copies).
Why? If I could be able to keep the symbols consistent, like not defining one that has already been used or something similar it shouldnt have any problem. I want to use wave to analyze the source, not to create a preprocessed output.
