jflex - a lexical analyzer generator (also known as scanner generator) for Java


jflex <options> <input-files>


JFlex is a lexical analyzer generator (also known as scanner generator) for Java(tm),
written in Java(tm). It is also a rewrite of the very useful tool JLex. JFlex is designed

Yacc BYacc/J. It can also be used together with other parser generators like ANTLR or as a
standalone tool.
