Open Source Java Code Generators for Linux

Jad Java decompiler plugin for Eclipse IDE.

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.

z390 Portable Mainframe Assembler and Emulator

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

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).

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.

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.

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

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.

openASN.1 is an Open Source Java toolkit for the Abstract Syntax Notation One (ASN.1) which consists of a compiler and codec with a low footprint runtime library.

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]

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.

XML encoder for source code

JadRetro is a Java decompiler helper supporting Java 1.5+ classes. JadRetro is not a decompiler itself, it is a class transformer helping some old (but good) Java decompilers to convert more class files and/or generate more correct source code.

JAC (Java Asn1 Compiler) is a tool for you if you want to (1)parse your asn1 file (2)create .java classes and (3)encode/decode instances of your classes. Just forget all asn1 byte streams, and take the advantage of OOP! BER, CER and DER are all supported

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

Runtime library for the JUndo language. See http://verdantium.blogspot.com/

TreeDL (Tree Description Language) is a notation for tree structures used by programs (like syntax trees) and tool for translation of tree descriptions to target programming language, docs generation, etc. Tool's functionality can be extended by plugins.

In simple words, JEX is a redefinition of Java using an XML syntax. This allows programmers to extend their favorite language. It also simplifies compilers, IDEs and code generators. Among foreseeable extensions are UML diagrams , Design Patterns...

Plugins for Maven 1.x (http://maven.apache.org/maven-1.x/) - manage all aspects of your project (tests, docs, distribution) from a single project descriptor! This project provides plugins that are not bundled with Maven due to differing licenses.

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.

RECODER is a Java framework for Java program analysis and source code transformation. It computes an easy to use syntactic and semantic program model containing cross references, and it supports transformation rollbacks and incremental model updates.

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.

A Java bytecode weaver that enables you to take advantage of the new 1.5 language features in your source code, while still retaining compatibility with 1.4 virtual machines.
