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.
Config4*, pronounced "config for star", is a family of configuration-file parsers. It currently provides C++ and Java implementations. It offers an incredibly flexible and user-friendly syntax and an API with powerful features not available in other configuration technologies such as XML, JSON, Java properties, or the Windows Registry. The comprehensive and easy-to-read documentation includes a getting started guide, expert tips, API reference manuals, and a maintenance guide.
