Components + GLoo

We are advocating a component-oriented software development approach that provides support for a clear separation between the computational and the compositional entities of an application. This principle is best captured by the application building paradigm “Applications = Components + Scripts.” However, the biggest obstacle for a successful use of this maxim originates from the choice of the scripting mechanisms being used to define applications as compositions of reusable software components. In this paper, we analyze GLoo, a novel component-oriented programming framework, which derives its expressive power from an extensible and open-ended scripting language. The design of GLoo aims at a higher-level, scalable, and problem-oriented software development approach, which enables simultaneously both small-scale and large-scale software development through the definition of specially-designed domain sublanguages.
