D2Bridge Framework

D2Bridge Framework is Delphi and Lazarus for Web Your Delphi or Lazarus code compiling for the Web using the Delphi and Lazarus way, synchronous on the Web. D2Bridge is Open Source. D2Bridge is the framework that allows you to code normally in Delphi while maintaining your code synchronously, allowing you to focus on your Delphi project as you always have and compile for the Web Generates responsive HTML code compatible with Bootstrap 5 and the latest Web technologies It already comes with Templates and its web interface can be different from your VCL project without changing its code No additional components are necessary when exporting to the Web. D2Bridge recognizes and intercepts your visual components You can compile your application for Desktop and Web using the same code and the same interface that you already have in your project When compiling your application for the Web, you can choose between 3 very lightweight and powerful Web Servers (Console, Compact and Full) From a simple 'MessageDlg' response to a ShowModal or Timer, everything works on the Web in the same way as on the Desktop With D2Bridge Framework, your application has native support for multiple languages, allowing you to easily write your application for the world to see. You can use D2Bridge Framework normally for any purpose, including projects for commercial purposes

Pascal NUCLEUS (GUI/VM)

NOTE: As of r816, Nucleus source code is licensed under GPLv3. (8th Oct 2017) Nu|cleus [ˈnjuːklɪəs] - The central and most important part of an object, movement, or group, forming the basis for its activity and growth. This is yet another long-term project (YALP?). The aim is to write a portable GUI/OS for Atari ST, Amiga and DOS. The code must be small, fast and support modern GUI features. ie: Embedded component controls. The code current compiles with Highspeed Pascal (Atari ST) or FreePascal. I hope to have it compiling for the Amiga (also using Highspeed Pascal), and supporting a built in p-code compiler/interpreter for cross platform development.

qxotica - tools for qooxdoo

Includes a package for the Lazarus IDE that adds items to the File | New dialog. Selecting "qooxdoo JavaScript App" creates either a single-page or two-page master-detail qooxdoo app and a Lazarus project for managing and editing the app's JavaScript files. Selecting "qooxdoo JavaScript Page" adds a page to the app and to the Lazarus project. Can also "compile" (run generate.py) from within Lazarus - if a syntax error is detected, the code editor jumps to the JavaScript file and line where the error is located. Also includes full source code for the Unicodum demo app. This is a Unicode viewer consisting of a qooxdoo-based mobile client and a choice of Pascal (FCGI) or PHP server app.

Bug Finder

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 .

Tiger

Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.

Ganymede

Ganymede is a high-performance, embeddable scripting engine designed to compile source code directly into native x64 machine code via Just-In-Time compilation. It eliminates the need for virtual machines or interpreters, providing a flat C-style API for seamless integration with C++ and Delphi applications.

PUMA Repository

The PUMA Repository is a collection of Pascal units for medical informatics. It contains reusable source code for a wide field of health-care application development. The code includes a support engine for the European Data Format (EDF and EDF+), converting functions for units of measurement and an HL7 engine. PUMA is compatible with Lazarus and Free Pascal. Some of the units also support other Pascal implementations including Delphi, winsoft Pocket Studio and other compilers.
