or have the same interest with me. Maybe we can discuss it.
I am not a Flex developer, but I doubt it,
because the same question has some up a couple of
times about Bison, and there, really nothing is
available. The best way might be to read the
sources and in books about lexer generator
construction. For example, Flex uses a fairly
standard two step regular expression -> NFA ->
DFA construction. You might also ask in the
newsgroup comp.compilers, and checking its FAQ,
published there monthly. Also, the latest Flex
versions, including CVS, are available at:
