A lexical analyzer generator that makes the class source code.
ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.
Translates state machine into a target programming language.
SMC takes a state machine stored in a .sm file and generates a State pattern in 14 programming languages. Includes: default transitions, transition args, transition guards, push/pop transitions and Entry/Exit actions. See User Manual for more info.
SableCC is a parser generator which generates object-oriented frameworks for building compilers, interpreters and other text parsers. SableCC keeps a clean separation between machine and user code which leads to a shorter development cycle.

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.
JTools provides some useful tools and utilities for Java 5.0 development.
Beneath some smaller utilities we have:
a (Ant like) DAO framework (also including XML Repository) and
a (JSP like) general purpose template generator and execution framework.
Lapg is the combined lexical analyzer and parser generator, which converts a description for a context-free LALR grammar into source file to parse the grammar. Generates code for Java, Javascript, C, C++ and C#.
UfakPython is a small subset of Python programming language, for small embedded devices, like PICs. UfakPython sources are translated to C by UfakPython Compiler. Small Device C Compiler can then compile the C outputs to the target device's codes.
ParGeL is an LALR(k) parser generator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.
More Than Parsing is a parser generator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
STDL (Structured test description language) is a domain-specific testing language that is used to auto-generate unit test code. It supports a myriad of output languages (incl. C#). The project's aim is that of reducing the resources required for testing
Covra is a project to help design compilers. C3 is a tool specialized on the easy design and construction of ASTs, it is independent of the compiler compilers or parser generator that is used. It generates Java and C# code. Require JRE 1.6.0.
BNF for Java is a BNF Compiler-Compiler, or Parser-Generator. It implements ISO Standard Backus-Naur Format, using Java. BNF allows you to create a syntax, or a complete language, to parse your data source. Your custom Java extensions generate output.
jbytecode is a Java bytecode disassembler/assembler written in Python. Dissasembly code is aligned with Java bytecodes in the class file so modification and re-assembly is always possible, even when class is obfuscated.
Berkeley Yacc is an LALR(1) parser generator. Berkeley Yacc has been made
as compatible as possible with AT&T Yacc. Berkeley Yacc has been extended
to generate Python, Perl and Java code.
The CCC Language is yet another programming language. It is platform-independent, compact, and robust. Supports many SQL engines, has own ISAM DB engine, has terminal mode and more UI-s, is object-oriented, but it is compiled and not interpreted.
EGG is a development tool for fast and easy realization of XML to plain-text tranformations.
It's similar to XSLT, Velocity or JSP but emphasises source-code generation in a model-driven, generative development-process. For Windows or Unix with Java.
classgen is a Java class generator. It produces classes for abstract syntax trees in compiler frontends from simple and compact specifications. Generated classes have builtin support for the Visitor design pattern.
Blade Language Developer (or Project Blade for short) is a toolkit for creating domain specific or general programming languages. The toolkit offers a language for describing grammars, and templatable parser generator.
