    Dear ImGui

    Dear ImGui

    Bloat-free Graphical User interface for C++ with minimal dependencies

    Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies). Dear ImGui is designed to enable fast iterations and to empower programmers to create content creation tools and visualization / debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries. Dear ImGui is particularly suited to integration in games engines (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard. The core of Dear ImGui is self-contained within a few platform-agnostic files which you can easily compile in your application/engine.

    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.

    Redshift

    Redshift

    Adjust the color temperature of your screen according to surroundings

    Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night. This program is inspired by f.lux. Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. At night the color temperature should be set to match the lamps in your room. This is typically a low temperature at around 3000K-4000K (default is 3700K). During the day, the color temperature should match the light from outside, typically around 5500K-6500K (default is 5500K). The light has a higher temperature on an overcast day.

    Agar

    Agar

    Cross Platform GUI Toolkit

    Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.

    XmHTML is a HTML widget for Motif. It supports HTML 3.2. Since HTML 3.2 is an older version of HTML, XmHTML is primarily useful for displaying help texts or to visualize results of computations in an application. XmHTML is an old project with contributions from many people. It was abandoned for a while and was reactivated because Arahne, d.o.o. ( 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.
