parsing - Is it possible to have two or more Lex/Yacc parsers in the same application

Question

I have an application where I already have a parser for one sort of grammar and I need to add a second different grammar for another purpose.

Is it possible to have more than one?

And if so how do you get another entry point?

Thanks

Answer 1

I think you can to this by using the --name-prefix option to Bison, and the --prefix option to Flex.

In both cases they allow you to replace the default "yy" prefix used on the functions generated with a prefix of your own choice.
