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 BSD-licensed implementation of compilation tools (nm, ar, as, ld, etc.) for the ELF object format.

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.

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.

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

A RAD GUI Building IDE for wxPython.

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 PDB file dumper and C++ wrapper library for the Microsoft Debug Information (DIA) 2.0 SDK.

xacc.ide is a opensource IDE aimed at mainly .NET development. It has a code editor written in 100% C# code, which is faster than most commercial offerings.

Adebug/Assemble is a pair of Debugger/Assembler for the MC68Xxx family running on Atari and Amiga computers. Years ago commercial product, now GPL.

We develop a PHP application server, web application framework and a suite of web apps along with a set of tools (based on Eclipse) to configure the app server and web apps and build the site. Also included are FCKeditor, The GIMP, and AMP+Eclipse.

Main features: wxHatch is a cross platform IDE for wxWigets. It generates new wxWidgets projects, with a main frame and text or drawing/imaging window, provides a simple code editor with syntax highligthing, generates makefiles for

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.

Integrated development environment for creating, editing, compiling, translating, debugging and profiling portable brainfuck programs.

Este é um projeto acadêmico, desenvolvido pelos alunos da Univali do campus de São José, estudantes da Linguagens formais e autômatos. O objetivo deste trabalho é desenvolver um projeto de compiladores.

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.

Java Decompiler, Disassembler and Bytecode debugger. Decompiler supports Java 5 (e.g. generics, for-each loops etc). Debugger allows user to step through each bytecode and view program state. Contains Swing GUI.
