Open Source Java Compilers for BSD

unluac is a decompiler for Lua 5.0 through 5.4. It runs on Lua chunks that have been compiled with the standard Lua compiler. It requires that debugging information has not been stripped from the chunk. (By default, the Lua compiler includes this debugging information.) This program is written in Java. A JAR package is available in the downloads section so you don't have to compile it. It runs from the command line and accepts a single argument: the file name of a Lua chunk. The decompiled code is printed to the standard output. Here is an example usage of unluac: java -jar unluac.jar myfile.lua > myfile_decompiled.lua The current version also has pretty good support for Lua 5.0 and Lua 5.1. Support for later versions is also good if the code doesn't use too many gotos.

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.

Jasmin is a Java Assembler. It takes ASCII descriptions for Java classes, written in a simple assembler-like syntax. It converts them into binary Java .class class files suitable for loading into a Java Virtual Machine implementation.

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.

Verto is a compiler that uses a top-down recursive descent parser implemented in Java for educational purposes. It translates Verto language (a subset of the C language) into Caesar machine language. Verto is the Latin word for interpret.

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

z390 Portable Mainframe Assembler and Emulator

EJE is a simple Java editor, perfect to learn Java, without learning a complex development tool. EJE is multi-platform (written in Java), light- weight, user-friendly and have several useful basic features. A good help to start with Java! Supports the study of the Java for Aliens book (www.javaforaliens.com), or other my books (Italian Language) like www.nuovojava.it. You don't need to install the JDK anymore (the runtime is embedded). See the video "How to create the "Hello World App in 20 Seconds" at https://www.youtube.com/watch?v=aKiEAGbEk2k

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.

The Open Fortran Project (OFP) provides a Fortran 2008 compliant parser and associated tools. These tools provide a Java and C API for actions called when parser rules are completed. It also provides Fortran interfaces to the OpenCL runtime (new). IMPORTANT NOTICE: The Open Fortran Project has switched to using a parser based on SDF (Syntax Definition Formalism). Please consider using our new work at https://github.com/OpenFortranProject/ofp-sdf. While the SDF parser is not as advanced as the ANTLR-based parser, it provides much more capabilities, including a term rewriting system for creating a Fortran AST (Abstract Syntax Tree) using Stratego/XT (see http://strategoxt.org) and other custom program transformations. The OFP ANTLR-based parser is no longer under active development.

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.

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.

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.

A Java 2 (JDK 1.3/1.4) compatible virtual machine. joeq is unique in that it is almost entirely implemented in Java, making it reliable and efficient. It is also language-independent, so code from any language can be seamlessly and dynamically compiled.

RES is a pure Java based Open Source Cobol to Java translator. It creates maintainable Java code for a subset of VS Cobol syntax. It has been developed with JDK, JTB and Javacc.
