Java class file shrinker, optimizer, obfuscator, and preverifier
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.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.
You asked, we delivered! Auth0 is excited to expand our Free and Paid plans to include more options so you can focus on building, deploying, and scaling applications without having to worry about your security. Auth0 now, thank yourself later.
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.)
High-quality QR Code generator library in Java, TypeScript/JavaScript
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.
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.
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.
New customers can spin up VMs, build with AI, and query data at no cost.
Put your $300 in credit toward real workloads, then keep building with free monthly usage for 20+ products. No commitment and no charge until you upgrade.
The JavaCC Eclipse Plugin provides a JavaCC & JTB editor and a builder which process .jj, .jjt & .jtb files and integrate with Eclipse's incremental build system.
Compatible with Eclipse 4.6.0+ and Java 1.8+. Also embeds JTB 1.5.1.
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.
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.
Translate files between XLS / XLSX and XML format . . .
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.
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
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.
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
A generator of DTO, Model, and DAO classes to access relational DB
SQL DAL Maker is a generator of DTO, Model, and DAO classes to access relational databases. Target programming languages: PHP, Java, C++, Python, and Go. To generate the class, you declare it in XML meta-program.
At the stage of code generation, the target database must exist and be available for JDBC connection. Generated code is being synchronized with the current database schema using "live" JDBC metadata.
Written in Java. Implemented as plug-ins
For Eclipse: https://marketplace.eclipse.org/content/sql-dal-maker
For IntelliJ: https://plugins.jetbrains.com/plugin/7092
HOWTO install-update: http://sqldalmaker.sourceforge.net
GitHub: https://github.com/panedrone/sqldalmaker
Quick-Demo in mp4: https://github.com/panedrone/sqldalmaker/releases/tag/latest
Umple is technology for Model-Oriented Programming. It adds abstractions such as UML associations, attributes, and state machines to object-oriented programming languages such as Java, C++, PHP and Ruby.
A developer can use Umple in one of several ways. They can start with a pure model, containing only classes, associations, attributes and state machines, and then gradually add methods in one of the base languages to the Umple code base. Alternatively a developer can start with a normal program in a language like Java, and add modeling constructs in very small increments, gradually moving their system from a code-centric system from a model-centric system. Either way, Umple provides top-quality code generation.
Umple is being used, for real systems. In fact the Umple compiler itself was written in Umple. Any Java, C++ or PHP project could use Umple.
The UmpleOnline web app provides a quick way to explore the Umple approach. It is at http://try.umple.org
