[antlr-interest] v3 - How to deal with include Files?

[Alexandre Porcelli]

Now I understood your solution, but isn't it more complicate? Because
you will need to handle lexical instructions inside the input stream
(you can have several different kinds of "include" statements in
several languages - include, copy, -inc, ...) and we can have same
more sofisticates include statements (like an ASP file that is not
just a statement is a tag).
And the second problem that I can see with this solution is to control
file positions (line and column position) because you will need to add
one more internal thing : fileName (to get info about what is the
active file name).
I´d like to know your opinion about this.

Alexandre Porcelli
