Open Source Java Code Generators

Jad Java decompiler plugin for Eclipse IDE.

z390 Portable Mainframe Assembler and Emulator

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.

The aim of this project is to develope a decompiler for java which is platform independent and has options to obfuscate the class file also. The project takes class file as input and decompiles it and provides the source file.

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.

jdec is a Java Decompiler. It can be used to reverse the bytecodes present in a .class File to produce a Java Source File which can be nearly correct or equivalent (Due To different Interpretations) to the original java file.[With UI & command line]

Xsemantics is a DSL (implemented in Xtext itself) for writing type systems, reduction rules, interpreters (and in general relation rules) for languages implemented in Xtext. It then generates Java code that can be used in your language implemented in Xtext for scoping and validation (it can also generate a validator in Java).

Beaver is a LALR compiler compiler for Java that uses several techniques to generate very fast parsers.

Retrotranslator is a tool that makes Java applications compatible with Java 1.4, Java 1.3 and other environments.

XML encoder for source code

JavaGuard is a general purpose bytecode obfuscator, designed to fit effortlessly into your regular build and testing process, providing peace of mind that your valuable Java code is more secure against decompilation and other forms of reverse engineering

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.

ECL is a system-level specification language for HW/SW designs and is based on Esterel and C. The ECL compiler parses ECL, writes Esterel and C, and uses the Esterel compiler to produce an implementation. Originally developed at Cadence Berkeley Labs.

Pizza is a small, fast and free compiler for Java and an important superset of the Java programming language. It is written in Java/Pizza and compiles to Java class files.

Java-based BURG (code emitter generator), used by Adobe ASC 2.0 and Apache Falcon ActionScript compilers.

Compose* is a project that aims at enhancing the modularization capabilities of component- and object-based programming. In particular, Compose* offers aspect-oriented programming through the composition filters model.

Java Decompiler, Disassembler and Bytecode debugger. Decompiler supports Java 5 (e.g. generics, for-each loops etc). Debugger allows user to step through each bytecode and view program state. Contains Swing GUI.

Metaprogramming: proof of the concept.

A framework for data-flow based program analysis, implemented as a set of Java APIs. By using this framework, researchers and developers can easily implement analyses, test their correctness, and evaluate their performance. In addition, the framework all

Hades aims to become the reference open source environment for developing, validating and deploying PLUTO (Procedure Language for Users in Test and Operations) procedures.

This sourceforge site for the project is now DEPRECATED and not updated. All current work and new releases are on github: https://github.com/OpenJML/OpenJML. The Java Modeling Language (JML) is a behavioral interface specification language that can be used to specify the behavior of Java modules (as in design by contract -- DBC). It has many tools to do assertion checking, unit testing, etc. The principal current tool of the project is OpenJML -- cf. https://www.openjml.org, with binary downloads from https://github.com/OpenJML/OpenJML/releases/latest

This project has moved to http://github/mlhartme/mork.

C3PO is a software synthesis tool that provides a solution for building maintainable, reliable and robust software infrastructures and/or compiler frontends from a set of attributed grammar rules in EBNF notation.

Grammar based parsing in Java 8 to a tree structure. Create with no overhead a grammar in java and parse it into a tree structure. Will probably work right away with your grammar.

Argus is a highly integrated Eclipse plug-in. The purpose of this plug-in is to add additional Errors and Warnings to the Eclipse Framework, assisting Java programmers to create bug free, high quality code.
