Open Source Debuggers

The Lazarus IDE is a stable and feature rich visual programming environment for the FreePascal Compiler. It supports the creation of self-standing graphical and console applications and runs on Linux, FreeBSD, MacOSX and Windows.

Lazarus is a free and open source development tool for the Free Pascal Compiler. The purpose of this project is to serve as a Code Repository, Wiki Knowledgebase and support site for converting existing components and libraries to work with Lazarus and the Free Pascal Compiler.

A RAD GUI Building IDE for wxPython.

After a program has been thrown into the world in binary form, it can boomerang back as source code. The Boomerang reverse engineering framework is the first general native executable decompiler available to the public.

ELFIO is a header-only C++ library intended for reading and generating files in the ELF binary format

Java AS400 RPG source code editor, debugger, IDE.

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

A suite of Java ClassLoaders that use "load-time reflection" (the modification of bytecodes upon class loading) to extend existing Java classes. It uses the excellent BCEL library (http://bcel.sf.net).

Implementation of Aspect Oriented Programming (AOP) for Erlang. The AOP weaver is running against a target set of source files and controlled by aspect definitions. The weaver is implemented as a parse transformation function of Erlang compiler.

A subset of the TestCon project, ConAn builds on Roast to provide a testing framework for concurrent Java components. For more details on the development of ConAn and TestCon/Crom, see http://longbrothers.net/brad/papers/thesis.pdf

Cricket Cage automatically creates JUnit TestCases for repeatable bugs and test scenarios. Include Cricket Cage's AspectJ code to install a code generator, then run the program to generate the TestCase. Finally, add the test case to your build.xml.

Easy to use Java utility to collect method level performance data for any Java applications without modifying its code.

Tho goal of this project is to provide an integrated development environment for developing (x)Harbour applications on various platforms.

Java-program to read, modify and execute class-files. a real java VM written in java or a decompiler for class-files is possible (and partially working)

A highlevel API to instrument Java bytecode. Jiapi can be used to modify bytecode of a Java class before it is loaded into a virtual machine.

The Language Processing Agency provides agents and an agent-oriented infrastructure for developing language processors in .NET. Typical language processors are transformation tools, extraction tools, language interpreters, etc.

LLVM is a unique compiler infrastructure designed for the optimization of programs from arbitrary programming languages. Compilation in C and C++ programs is supported using a parser based on GCC 3.4. Backends exist for X86, Sparc, PowerPC and "C".

MODOCC - MOnitoring of Distributed Object Communication for CORBA is a project that allows monitoring of invocations on remote CORBA objects.

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.

NReflector is an extensible, open class browser and analysis tool for Mono/.NET. It allows users to browse Mono/.NET assemblies, search for methods/types and analyze their usage in an intuitive way.

ObjectBlox is a collection of libraries and utilities that provide a variety of useful services and functions for building distributed, cross-platform applications. It is written entirely in C# and runs on the .Net and Mono runtimes.

Quilt is a Java software development tool which measures coverage, the extent to which testing exercises the software under test. It works very well with Ant and JUnit but may also be used in conjunction with other products.

Unfortunately this project has been suspended. If you wish to continue its development on your own, please feel free to contact me. UnPyc is a tool for disassembling, analyzing and decompiling Python's *.pyc and *.pyo files. UnPyc supports Python 2.5, 2.6.

The XPS is a scalable platform for meta-programming and domain engineering. It provides a virtual machine, compiler, and runtime library that make it possible to efficiently develop, debug, and run programs based on XPL (eXtensible Programming Language)
