Project Description

JFlex is a flex-like lexer generator for Java with emphasis on speed and full Unicode support. It works as a standalone tool or together with the LALR parser generators CUP and BYacc/J. JFlex has support for some not so usual features like negation in regular expressions and nested input streams. It can also read JLex specifications unchanged.
