How could I use a namespace like yy (the same way bison does) for the generated
scanner with the C++ interface ?
I tried to open "namespace yy {" at the %top of the file, and to close it "}"
at the bottom, but all the included standard headers in the generated scanner would be included in
the namespace yy this way, instead of the expected global namespace.
I had no other idea than to explicitly include the C/C++ standard headers used
by the scanner before I open the yy namespaces, at the top of the file, so that
when the scanner later includes them, they will each see they have been already
included and skip over any included content.
Can namespaces please be added to flex C++ interface ?
Flex does not currently have active developers, and the C++ lexer was written a
long time ago, before namespaces was a part of C++. You might try modifying the
skeleton file, though.
