I didn't notice at first either, but he hid a "C library" constraint in
the Subject.
I can't recommend a library, but I *can* tell you that email addresses
aren't regular, so a regular expression is wrong. Observe:
foo(@example(.net))@example.org
==> [email protected]
You need a CFG because comment nesting implies context. I don't have an
EBNF handy, the RFC probably includes one.
I had a quick look, but I can't see a C library that *just* parses email
in apt. You probably need one that parses (say) message/rfc822 in
general, and just use the address parsing function.
PS: for perl, libemail-address-perl (Email::Address) is the thing.
