RE/flex lexical analyzer generator Reviews

Easy to use, out of the box support for moving from flex Additional syntactic features for generating regexp Matcher functionality in rules sections enables additional options for distributing logic between parser and lexer Compatible with UTF16 input which was a great deal breaker for my application

It's a fast and very user friendly flex derivative c++ scanner which provides more functionality over Flex. I find it more interesting when I used it for my grad level compiler project. So, I personally recommend people who use Flex/Lex should give a try to use RE/Flex for once and see the difference.
