I have a similar question.

What I want: a tokeniser generator which can take a lex-style grammar (not
necessarily lex syntax, but a set of token specifications defined by
REs, BNF, or whatever), generate a DFA, then run the DFA on sequences of
bytes. It must allow the syntax to be defined at run-time.

What I don't want: anything written by someone who doesn't understand the
field (i.e. anything which doesn't use a DFA).
