    ToaruOS

    ToaruOS

    Hobby operating system, bootloader, kernel, drivers, C library

    ToaruOS is a "complete" operating system for x86-64 PCs and experimental support for ARMv8. While many independent, hobby, and research OSes aim to experiment with new designs, ToaruOS is intended as an educational resource, providing a representative microcosm of functionality found in major desktop operating systems. The OS includes a kernel, bootloader, dynamic shared object linker, C standard library, its own composited windowing system, a dynamic bytecode-compiled programming language, advanced code editor, and dozens of other utilities and example applications. There are no external runtime dependencies and all required source code, totaling roughly 100k lines of (primarily) C, is included in this repository, save for Kuroko, which lives separately. Through out the project, ToaruOS has also attracted quite a few beginner OS developers who have tried to use it as a reference.

( www.arahne.si ) ordered the following enhancements in XmHTML from Christian Linhart: *support for antialiased XFT fonts *support for UTF8 text

    wxPHP

    wxPHP

    PHP bindings for the cross-platform GUI library wxWidgets.

    wxPHP is a php binding/wrapper for the cross-platform library wxWidgets, which gives you the ability to develop desktop applications using the php programming language. This applications can be executed on windows, linux and macosx using the same code base with a native look and feel. One of the ideas is that you can use your php web applications code base and logic to create native desktop applications that communicate to them transparently. This way you can give your users a seamless and native experience from the desktop while staying in sync with your web apps. There are many more use cases, but we invite you to download and try this project by your self. We hope everyone can enjoy it as much as we have enjoyed developing it.

    Gtk3.7 and Gtkmm3.6 for Windows

    Gtk3.7 and Gtkmm3.6 for Windows

    Gtk3 stack for Windows Vista/7/8 : Gtk+ 3.7.2 and Gtkmm 3.6.0

    This is the Gtk 3.7.2 stack installer; It includes all Gtk dependencies required for Gtk+ and Gtkmm. The Gtk+ stack was built in version 3.7.2 and finally, the Gtkmm stack in version 3.6.0.1. Each library was built with Visual Studio 2012 in 32 and 64 bits without the Windows XP support. This build passes many test on Windows Vista, 7 and 8 with many applications and official samples built with MSVC 2012 on Windows 7, with MSVC 2010 and with MSVC 2008 on Vista and MSVC 2012 on Windows 8. The installer allows the user to choose the most appropriate installation for him (only Gtk+, only DLL, only 32 bits, full installation 32/64 bits with Libs and headers, etc...) Enjoy !

    Unicoder

    Unicoder

    A Portable Wide-Character Terminal Output Package for C and C++

    Unicoder is a single header file that you add to your C or C++ projects which allows you to easily display unicode characters in the Terminal display irregardless of what compiler you are using. That is, it was written so that it would be portable so you can change platforms or compilers with ease. Currently it can be used on either the Windows or Linux platforms. Also, Unicoder can insert compiler specific commands that perform useful task such as clearing the console display or turn on bold and underline or change text font and background colors. And it provides a rudimentary way to draw on the display. Currently, Unicoder supports Ubuntu-Linux GCC and on Windows it can be used with these IDEs and compilers: MS Visual Studio 2017&2019, Code::Blocks, Pelles C, Embarcadero Dev-C++, Open Watcom, MSYS, MSYS2, Cygwin and with MinGW, Clang, LCC and Digital Mars C (but Digital Mars does not support Unicode!)
