libNUI is a hardware accelerated GUI framework that makes it possible to build rich multi-platform applications based on 3D rendered dynamic layouts. Interfaces are built as a composition of widgets and behaviors, and the framework handles positioning, resizing, anchoring, and texture stretching. Objects are connected with synchronous events and delegates for mono-threaded communication, or asynchronous notifications and message queues are used for multi-threaded applications. It also supports strings (including Unicode), paths, files, data streams, fonts, threads, critical sections, audio buffer rendering, and more.
NSFileHandleExt is an Objective-C extension (Cocoa/GNUstep) for the NSFileHandle class (which handles files/sockets). This extension provides support for much easier network programming for protocols like HTTP, IRC, telnet, etc. (everything that sends messages in lines suffixed by \n).
Democracy Player is a cross-platform Bittorrent-enabled RSS aggregator with built-in video playback that seeks to make watching Internet video from a wide range of sources as easy as watching TV. It is part of the Democracy Internet TV platform, which includes the torrent-enabled RSS publishing application Broadcast Machine and the video bookmarking site Videobomb.com.
SMS Framework is an Objective C framework for decoding SMS messages in PDU format to objects. It is easily usable in Cocoa and GNUstep environments, and it reduces developer responsibility for decoding messages to extracting the raw messages from the phone. The XCode project file contains three targets: one system wide framework, one framework to include in applications, and a small application for testing the framework.
HandBrake is a multi-threaded DVD to MPEG-4 ripper and converter. It can encode directly from DVDs (even encrypted ones) or from VIDEO_TS folders. AC3, LPCM, and MPEG audio tracks are supported. The output can be contained in MP4, AVI, or OGM files, and the output audio is encoded in either AAC, MP3, or Vorbis. Other features include support for 2-pass encoding, encoding of two audio tracks, a bitrate calculator, and deinterlacing, cropping, and scaling of the original picture.
DevelKit Framework is an GNUstep/Cocoa framework with tools for reading, understanding, and generating source code from other applications. Its goal is to allow applications to generate code from non-textual representation, such as diagrams or other kinds of descriptions. Example features: an ObjectiveC source reader and generator, a project builder class, source structure related classes (class, method, and instance variables), templates, a tool for automatically generating accessor (getter ad setter), dealloc and archiving methods (interface and implementation) for a given class, and more.
Tk Drag and Drop is an extension for Tcl/Tk to add native drag and drop capabilities to the Tk toolkit. It is designed for Tk versions 8.3.3 and higher. Native drag and drop are supported under Microsoft Windows (XP, Vista, 7), Mac OS X Leopard (Cocoa framework), and Linux (XDND, drag support missing).
mGSTEP is a software development framework designed primarily for use in embedded devices. It implements the core elements of NeXT's OpenStep that evolved into Apple's Cocoa Objective-C class libraries. The drawing API is a partial implementation of Display Postscript in parallel with the newer Core Graphics API. The stable GUI (AppKit) is X11 based. A Linux framebuffer based GUI backend is also included.
