nCore is an efficient and portable C++ library for developers. It includes a set of several satellite C++ classes to perform threading, file I/O (with endian-awareness), networking (TCP, UDP, IPv4, and IPv6), high-perf timing, easy logging with pluggable sinks, memory allocation debugging, hashing (MD5, string, CRC32, CRC16, and CRC8), loading of dynamic libraries (shared objects), dog-tagging (your final application/library binary file(s)), handling wide string manipulation methods through a single class (StringA), and more. Each of those features can be turned off at compile-time to make the final binary file smaller.
Mercat is a light-weight, cross platform programming language. It is garbage collected and self hosting and produces portable byte-compiled binaries that can be executed on any platform with the appropriate interpreter. Interpreters are available for Linux, DOS (32-bit) and DOS (16-bit) and the interpreter source should be easily compilable for other platforms.
PropXX provides a property/configuration mechanism for C++ applications. Properties can be defined in files similar to but more flexible than Java properties. Property files are defined in a type-safe, modular way and offer the full expressiveness of the Lua scripting language. The design of PropXX combines flexibility with high performance for the C++ code that accesses property values. The property values are stored in objects of special property classes, which are automatically generated from the property set definitions. Performance-critical code can be inlined by the compiler, and a typical access to a property value is as cheap as reading a single variable from the memory. No costly data structures like hashes, balanced trees, etc. are involved.
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.
