Treffer: ANALYSIS OF META-PROGRAMS:: AN EXAMPLE.

Meta-programs are generic, incomplete, adaptable programs that are instantiated at construction time to meet specific requirements. Templates and generative techniques are examples of meta-programming techniques. Understanding of meta-programs is more difficult than understanding of concrete, executable programs. Static and dynamic analysis methods have been applied to ease understanding of programs — can similar methods be used for meta-programs? In our projects, we build meta-programs with a meta-programming technique called XVCL. Meta-programs in XVCL are organized into a hierarchy of meta-components from which the XVCL processor generates concrete, executable programs that meet specific requirements. We developed an automated system that analyzes XVCL meta-programs, and presents developers with information that helps them work with meta-programs more effectively. Our system conducts both static and dynamic analysis of a meta-program. An integral part of our solution is a query language, FQL in which we formulate questions about meta-program properties. An FQL query processor automatically answers a class of queries. The analysis method described in the paper is specific to XVCL. However, the principle of our approach can be applied to other meta-programming systems. We believe readers interested in meta-programming in general will find some of the lessons from our experiment interesting and useful. [ABSTRACT FROM AUTHOR]
