Bison 2.5 has a "push api".
http://www.gnu.org/software/bison/manual/html_node/Push-Parser-Function.html

Does there exist something similar for lex of flex or does somebody know
a "push scanner"?

Thanks.

Detlef
[Not that I've ever seen.  It would be straightforward to modify flex
to create push lexers that work with push parsers, but so far nobody's
done it. -John]
