Open Source Object Pascal 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.

DUnit automates unit testing of Delphi code. The target audience for DUnit is developers who are both writing the code to be tested and the unit tests for that code, an approach advocated by Extreme Programming. Dunit is is a Delphi port of JUnit.

Disassembler for Windows(95-XP), currently supports PE, NE, MZ, COM and "unknown" executable formats. Includes also OS independent console version (but requires x86). Output syntax similar to NASM .

Yet another scripting language Main features: - Pointers - Structures - Objectoriented programming (yet to come) - code in plain english - easy to learn (based on C, C++, Java, Pascal, Python, Lua)

Le projet Atlantis est une collection de composants et de bibliothèques pour Lazarus. The Atlantis project is a collection of components and libraries for Lazarus.

The BF Debugger Project is an attempt to allow the development of software using the Brainf*** programming language in a GUI development environment, and to provide a platform for the advancement and dissemination of this language.

This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .

Tools to incrementally build customised Forth Virtual Machines for embedded applications. Token compiler converts token description into C code templates. PC console application includes FVM, it is used to compile and debug bytecodes for target FVM.

The stack tracer is an delphi library for help to make exception handling to informative. The library is written for Delphi 7, but i think will work also on the 5 and 6 versions.

dSpec is a BDD framework for Delphi/Pascal built as an extension of DUnit.
