A component-based framework and reusability in Garment

Garment is a mechanism for abstraction and encapsulation of languages. It aims to make the best support on the definition and implementation of new languages, especially DSLs (Domain Specification Languages). Garment originally provided a unified framework for defining languages and describing relations between languages. The framework is very convenient for defining and describing new languages. However it is not flexible enough to design some similar DSLs. We propose, in recent work, a component-based framework for the design of DSL where software reuse is a very important feature. In this paper, the component-based framework will be briefly introduced. A conceptual analysis of reusability in Garment is also made from the different points of view and different levels here.
