ANTLR
Parser generator to read, process, or translate structured text
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees. It’s widely used in academia and industry to build all sorts of languages, tools, and frameworks. Twitter search uses ANTLR for query parsing, with over 2 billion queries a day. The languages for Hive and Pig, the data warehouse and analysis systems for Hadoop, both use ANTLR. Lex Machina uses ANTLR for information extraction from legal texts. Oracle uses ANTLR within SQL Developer IDE and their migration tools. NetBeans IDE parses C++ with ANTLR. The HQL language in the Hibernate object-relational mapping framework is built with ANTLR. -

COBOL copybook to XML converter
Converts cobol copybooks to Xml/Java objects
CB2XML (CopyBook to XML) is a COBOL CopyBook to XML converter written in Java and based on the SableCC parser generator. This project includes utilities to convert an XML instance file into its COBOL copybook equivalent string buffer and vice versa. Source is now available in GitHub: https://github.com/bmTas/cb2xml -

This project has moved to GitHub ! The version here at SourceForge will remain for historic purpose. Koopa is a parser generator, made for COBOL. It can handle source files in isolation (no preprocessing required) and doesn't mind the presence of CICS/SQL fragments. The grammar is easily extensible in a way which minimizes the impact on the overall code.

Coco/S Parser Generator
Parser Generator based on Coco/R
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. -

JPlex
Java lexical analyzer generator
JPlex is an unconventional lexical analyzer generator for Java. JPlex lexers are NIO-based, DFA-powered, push-driven, and fully decoupled and reusable. Their state machines are precompiled and serialized, so run time initialization is fast no matter how large the rule set. JPlex is not a parser generator; it only generates an interface for its parsers, and it does not build a parse tree. When the lexer identifies a token that has a named event associated with it, it passes the token to the parser method associated with that event. A lexer can dispatch token events to any number of parsers. JPlex is steadily being improved, and the Subversion repo will almost always be newer and better than the binary download. -

lightJacc is a small but strong grammar parser generator. It adopts a parsing strategy of its own: dynamic concurrent parsing -- which made it much stronger than LR or LL family CCs (YACC, ANTLR, etc), but still keep good performance.
