Hi Martin,
If I understand your question correctly, here is a way to have multiple
scanners and parsers in the same program.
No, he's asking about using a subset of an existing grammar in a new parser.
Example: I have a language which includes a complex expression syntax. I
also have a separate preprocessor for the same language, which uses
exactly the same expression syntax. This means that I need to write two
completely separate flex/bison files, and maintain both of them, even
though one of them is a subset of the other one.
This would be a nice feature - I think it's been asked for before on
this list.
