If you have questions about particular ones, let + me know. + + reentrant + A set of mods contributed by John Bossom for adding + an option to flex to make reentrant scanners. + + rflex-2.5.4-diffs + A set of mods contributed by Chris Appleton for + the same purpose. + + streams + email from David Madden about coping with non-blocking + I/O. + + unicode + patches to support Unicode scanners, contributed + by James A. Lauth. + + +Of these, the ones that people frequently ask about are support for reentrant +scanners and support for Unicode. I haven't played with the reentrant stuff +so don't know how solid / well designed it is. I've sent out the Unicode +stuff to numerous people and haven't received any complaints, so I imagine +it works well. + +Another thing people ask for fairly often is removing the limit on size +of the scanners. There's some mail in the faqs/ directory about ways to +do this by cranking some #define's in flexdef.h, though of course the best +solution would be dynamic memory/resizing. + +By the way, I have translated the core flex algorithms into a C++ regular +expression class (but one that doesn't support the uglier stuff like +yymore()/yyless(), trailing context, etc.). If you ever wind up wanting +it, just let me know. |
