RE/flex is the fast lexical analyzer generator (faster than Flex) with full Unicode support, indent/nodent/dedent anchors, lazy quantifiers, and many other modern features. Accepts Flex lexer specification syntax and is compatible with Bison/Yacc parsers. Generates reusable source code that is easy to understand. Supports fast scanning of UTF-8/16/32 files, strings, and streams. The reflex scanner generator tool generates clean lexer class code that is thread-safe. Generates Graphviz files...

JFlex is a flex-like lexer generator for Java with emphasis on speed and full Unicode support. It has some not so usual features like negation in regexps and nested input streams. Also reads JLex specifications unchanged.

Coco/S is a compiler generator that takes plain EBNF grammar files and features a SAX style call back API. It is written in Java and produces a Java Scanner (Lexer) and Parser for the language described by the input grammar. Coco/S is a branch of the 2010/11 release of Coco/R for Java. While Coco/R takes an attributed grammar file, Coco/S has a callback API. This has the advantage of a clean separation between grammar (EBNF) and Compiler/Interpreter.

... 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.

KFlex is an extension to JFlex that makes it easy to generate lexers whose actions call methods of a listener interface. This simplifies parser development and makes the lexer a reusable drop-in component.

Java Cobol Lexer take a cobol source program and return it as a list of lexical tokens. Library takes source code in fixed, free and mixed formats. It recognizes standard Cobol 85.

Annotation based lexer and parser generator suitable for processing wide range of languages, from small domain specific languages to big ones like Java. Actions may be written directly as annotated java methods. Examples of expression language and Java5.

A run-time configurable character stream tokenizer that allows the user to define token classes via regular expressions. The developer is not limited to predefined notions of whitespace, commenting, or word modalities.

A simple to use, easy to be extended lexer.
