Components 4 Java is a development tool for Java. It provides a framework to organize and separate different parts of code, and fills the gap between the class level and the library level as provided by the Java SE architecture. Additionally, you can organize your classes in well-separated and loosely coupled components. Those can be stuck together graphically into larger compositions. Finally, components and compositions will be distributed among Java archives as specified in assemblies.
The Crossplex package of make macros simplifies the creation of embedded systems, and is powerful enough for large organizations to use for developing elaborate product lines. It allows you to organize many different products under a logical structure, making systems of any complexity easy to specify. When you have many different target platforms, each with multiple different software configurations, Crossplex keeps those configurations from stepping on each other, without requiring redundancy in your source tree. Crossplex allows you to use a single dependency tree encompassing both in-house software and third-party packages, and it is particularly suited to build automation. Crossplex makes it easy to shield your build from the host environment, setting all shell variables explicitly, and giving you complete control over the path that is used at any point in the build. This is nice when you want to support building on a variety of development platforms. Crossplex scales to your needs. You can dabble in the unpacking and patching features as you need them, or you can base your entire system from the ground up on the Crossplex framework. Crossplex supports creation and use of glibc and uClibc toolchains.
D:GameVFS is a minimalist virtual filesystem library for the D programming language oriented at game developers. It provides an easy-to-use API for filesystem-independent file/directory manipulation. It supports basic VFS functionality. Files and directories can be created, read, and written, but not deleted. There are no security features (e.g., D:GameVFS can't handle a situation in which a file it's working with is deleted outside the program).
DXF Export Java is a Java library for exporting CAD entities, along with their properties, to stream or AutoCAD DXF files at high speed and with ease. Creating a new DXF file takes only one call of the exporter class, provided that user data has been prepared and loaded to the required fields beforehand. The library handles all major entities, including Arc, Bezier, Circle, Ellipse, Hatch Pattern, Line, Multi-line Text, Pixel, Polyline, Rectangle, and Text. It also supports layers, colors, line styles, and other important properties. Source code and working demos are included.
DeltaQt is a cross-platform library of C++ classes and functions for parsing of DELTA (DEscription Language for TAxonomy) files, and is part of the Free DELTA initiative. Support for all major data-related DELTA directives is planned. Typesetting directives are beyond the scope of the project, and support for them is not planned. Support for RTF formatting within comments, notes, descriptions, etc. is planned. All data defined by supported DELTA directives (including comments and annotations) will be parsed into memory. Qt (core) is used extensively.
