Generative Programming Core Concept

0. Domain Modeling (Feature Modeling)

1. Active libraries are not passive collections of routines or objects, as are traditional libraries, but take an active role in generating code. Active libraries provide abstractions and can optimize those abstractions themselves. They may generate components, specialize algorithms, optimize code, automatically configure and tune themselves for a target machine, and check source code for correctness. They may also describe themselves to and extend tools such as compilers, profilers, debuggers, domainspecific editors, etc.

This perspective forces us to redefine the conventional interaction between compilers, libraries, and applications. Active Libraries may be viewed as knowledgeable agents, which interact with each other to produce concrete components. Such agents need infrastructure supporting communication between them, code generation and transformation, and interaction with the programmer.Active Libraries require languages and techniques which open up the programming environment.
