Open Source Debuggers

Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.

The m6800 Simulator is a teaching tool to introduce students to microprocessors. It is based on a cut-down version of the M6800 chip, and a reduced instruction set. The simulator assembles and simulates execution of the users code on a GUI

Tiny8051 is small 8051 microcontroller simulator written in C#. Project was created for educational purposes, to show how µP works by using clean visual interface and debugging. Note: communication over serial port was not implemented, because there was no demand for it.

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

This project aims to implement an LC2/LC3 assembler and simulator for the Linux and Windows platforms.

Version 4.0: improved history, error, and view mode handling Version 3.0: JavaScript editing, Quick console, History files for browsing and loading scripts. Version 2.0: CodeMirror functionality, ajax calls. Tired of opening an editor to test short code snippets for functionality, saving the file and then running it in a browser? PH_Playground provides a simple solution on a single browser page. Enter the code to be tested into the "PHP" or "JS" window and press "Run". The result will appear as Rendered or Raw HTML as you choose. In the background the code has been saved to a log file. Works on any machine running PHP. Log files are found in the Playground.log directory, sorted by year and month. A new log file is started every day and numbered accordingly. Warning! Do not use this program on a production site!

Bean Bowl is the a fun and useful Java lab, allowing you to play around with Java classes and objects using direct manipulation techniques instead of writing long main() methods. Use it either as an application or as a GUI component framework for you own

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.

ExStudio is a set of development tools for the "Ex" virtual machine. It includes the vm itself, a compiler, an assembler and a debugger.

File-Spector is a small, fast and easy to use binary file analyzer and Inspector. It allows the users to format a complete binary file structure and then use it to read any binary file that matches the specified format.

JTestCase uses XML file to organize multi-testcase data and asserting conditions (action and expected result), and provides a set of easy-to-use methods to retrieve test cases out from XML, and asserts results against those expected ones in data file.

OSProg (Open Source PRogrammer) is a device programmer project. The target is to provide with wide range supported devices (PROM, EPROM, EEPROM, PIC, MCU, etc) at low price, simple and flexible hardware design.

Testing tool for Semantic Bridges. Supports the evaluation of rule-based (SWRL) ontology mappings to provide trust in a distributed multi-actor environment with heterogeneous independent information models materialized in OWL ontologies. See QualiPSo.org

StaMS is a State Monitor System of Distributed Applications. Designed to use by distributed applications developers to monitor the states of a distributed applications.

Visual DB Script is an editor PHP,ASP,HTML(can support other languages) that integrate the functionally of a Database Manager (like Access or MySQL). It supports Scripting Developers with specifical SQL commands and an SQL Query Designer

wspacegen is an interactive IDE for programing with whitespace (http://compsoc.dur.ac.uk/whitespace/). So it's possible to create .ws code relative easily and debug it as well. But attention, you'll addicted to it (-:

Decompiler for 1C Enterprise 7.7

A Lisp multilanguage design implemented on Smalltalk. Featuring an OOP macro system that works across all the languages. Contains all other languages as Lisp dialects. Fully OOP. Fully documented guided tour. language specs too. assembler, prolog, C#...

Enables a user to view & alter all aspects of comunications with a web site via a proxy. Primarily used for security based penetration testing of web sites, it can also be used for debugging during development. Seen as part of a hacker toolkit.
