The STX ExecPipe library provides a convenient C++ interface to execute child programs connected via pipes. It is a front-end to the system calls fork(), pipe(), select(), and execv() and hides all the complexity of these low-level functions. It allows a program to build a sequence of connected children programs with the input and output of the pipe sequence redirected to a file, string, or file descriptor. The library also allows custom asynchronous data processing classes to be inserted into the pipe or placed at the source or sink of the sequence.
SupplyChain is a C++ library that simulates a supply chain. It takes full advantage of concurrent programming and multi-core CPUs without the programmer having to know anything about it. A supply chain consists of two mandatory components: initial producers and final consumers. Apart from these components, a supply chain can include any number of manufacturer nodes. Each node can contain any number of elements of its own type. These elements allow very powerful supply chains to be modeled and constructed.
The JsonMe++ (JSON Made easy for C++) library is a C++ wrapper for the JSON-Glib C library. The library makes heavy use of C++ syntactic sugar type C++ language constructs, most notably the subscript operator and cast operator as essential API components, which makes this JSON library extremely simple to use. As a result, access to a deeply nested value from a piece of JSON data can be expressed simply.
The X3D library is used to load an X3D file and render it using OpenGL (an X3D file is an XML file describing a 3D environment that can be rendered with OpenGL.) The library supports all the objects as defined in the X3D specification in 2006. The render library is still somewhat limited, though. It works well under Linux. It is likely to work on any Unix, and has worked under MS Windows before. The project includes a test that makes use of FLTK version 2.0-m3. That version of FLTK can be downloaded from the project repository, as FLTK itself actually ended up not publishing a concrete 2.0 version of the library.
