    Automaton Lexer

    A Java library for creating DFA-powered lexical analyzers

    This project is derived from the dk.brics.automaton DFA library, version 1.11-8. The most significant change is the addition of a 'info' field to automaton states, allowing them to be associated with a token type. A few automaton operations were modified to preserve the value of this field. I have not given much thought to whether it would even make sense to preserve the 'info' field through some of the other operations. This project also includes an extension of RunAutomaton, called TokenAutomaton, that can be used as a lexer, as well as its support classes and examples of its use. Lexers generated by JPlex depend on this library. I separated it from JPlex so that projects using JPlex would not depend on GPL code. Revision 1 of this project is dual-licensed, as it is the same code that was formerly part of JPlex. All code in this library was either originally published under the BSD license or was exclusively authored by me.
