Open Source Java Code Generators

ProGuard has moved to Github now: https://github.com/Guardsquare/proguard ProGuard is a free Java class file shrinker, optimizer, obfuscator, and preverifier. It detects and removes unused classes, fields, methods, and attributes. It optimizes bytecode and removes unused instructions. It renames the remaining classes, fields, and methods using short meaningless names. ProGuard is useful for making code more compact and more efficient, on the desktop, on tablets, on smartphones, and on embedded devices. It also makes code more difficult to reverse engineer.

Banish crusty code with the Uncrustify C/C++/C#/D/Java/Pawn source code beautifier. It indents, adds newlines, aligns, etc, and is highly configurable.

Allows editing of any size file in hexadecimal, decimal and ASCII. A great tool that allows you to edit and analyze the contents for either the data or resource fork of any type of file. 68K, PPC and Carbon run on MacOS 7-9 and X.

cglib has moved to https://github.com/cglib/cglib

Jalopy is a source code formatter/beautifier/pretty printer for the Java programming language. It is aimed to provide a full-featured, yet free alternative to the well-known Jindent. Plug-ins for Ant, Eclipse, IDEA, JBuilder, JDeveloper, jEdit, NetBeans.

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.

JPype is an effort to allow python programs full access to java class libraries. This is achieved not through re-implementing Python, as Jython/JPython has done, but rather through interfacing at the native level in both Virtual Machines. Maintenance and evolution of the project has moved! please see http://www.jpype.org for the latest version

Command-line/Ant-task/embeddable text file preprocessor. Macros, flow control, expressions. Recursive directory processing. Extensible in Java to display data from any data sources (as database). Can generate complete homepages (tree of HTML-s, images, etc.)

This project aims to be the best, clearest library for generating QR Codes. My primary goals are flexible options and absolute correctness. The secondary goals are compact implementation size and good documentation comments. This work is an independent implementation based on reading the official ISO specification documents. I believe that my library has a more intuitive API and shorter code length than competing libraries out there. The library is designed first in Java and then ported to TypeScript, Python, Rust, C++, and C. It is open source under the MIT License. For each language, the codebase is roughly 1000 lines of code and has no dependencies other than the respective language’s standard library.

The Whole Platform is a technology for engineering the production of software. We provide an Eclipse based Language Workbench for developing, manipulating and transforming languages using a model driven approach.

jOOQ generates Java code from your database and lets you build type-safe SQL queries through its fluent API. jOOQ is an internal DSL and source code generator, modeling the SQL language as a type-safe Java API to help you write better SQL.

SmartSlog (Smart Space Ontology) is a software/application development kit (SDK or ADK) for programming Smart-M3 agents (Knowledge Processors, KPs) that consume/produce smart space content according with its high-level ontological representation. SmartSlog applies the code generation approach: given an OWL ontology description, the ontology programming library is produced. The latter provides API to access the smart space via a Smart-M3 Semantic Information Broker (SIB) and data structures and functions to represent and maintain locally in KP code all ontology classes, relations, properties, and individuals. Since 2012 the project is supported by grant KA179 of Karelia ENPI programme, http://kareliaenpi.eu/ More information about project: http://oss.fruct.org/wiki/SmartSlog Smart-M3 on Wikipedia: http://en.wikipedia.org/wiki/Smart-M3

JiBX is a framework for XML data binding to Java. It works with existing classes, using a flexible mapping definition file to determine how data objects are translated to and from XML. See the Home Page for details and external bug tracking system links.

PREESM provides a complete framework for fast prototyping. It generates a simulation and an optimized multiprocessor code from graph descriptions of algorithm and architecture. Please visit the project homepage at http://preesm.sourceforge.net.

Druid is a GUI tool for database build and management. Users can add/change/delete DB objects (tables, fields, etc). Druid generates for you: SQL scripts, docs in XHTML, PDF, DocBook, etc; code in C, C++ & Java Beans even for JDO and support Castor & OJB

Jad Java decompiler plugin for Eclipse IDE.

XDoclet is an extended Javadoc Doclet engine. It's a generic Java tool that lets you create custom Javadoc @tags and based on those @tags generate source code or other files (such as xml-ish deployment descriptors) using a template engine it provides.

Community Z Tools Project (CZT): Tools for editing, typechecking and animating Z specifications and related notations. Includes a Java framework for building formal methods tools. NOTE: development of CZT has now moved to GitHub: https://github.com/community-z-users/czt

XLStoXML is a portable cross-platform desktop application for file format translation between XLS/XLSX and XML. No installation required except Java. The simple and intuitive interface allows you to do complex operations with just a few clicks. We are currently offering only a free version of this software, this means that all the features are available for you! The downloads and old versions code are distributed in SourceForge, and will be available soon. This piece of software is more than a simple converter. XLStoXML allows you to configure the translation in a wide range of combinations to reach out your requirements. Convert one or a bunch of files in short time. What else? Track your conversions in the console tab, see the errors or the success of each of the excel files. If you get stuck or you need support, we give you help in numerous ways: http://xlstoxml.sourceforge.net/#Support.

EJBGen 2.0 is an EJB extension module for the SrcGen project. It generates Java and XML source files based on meta-data supplied in the form of an XML document that conforms to a DTD/XML Schema that describes the structure of an Enterprise Java Bean.

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.

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.
