Chapter 5 An

Abstract In this chapter, we elaborate on the design of an industrial-strength aspect-oriented programming language and weaver for large-scale software development. First, we present an analysis on the requirements of a general purpose aspect-oriented lan-guage that can handle crosscutting concerns in ASML software. We also outline a strategy on working with aspects in large-scale software development processes. In our design, we both re-use existing aspect-oriented language abstractions and propose new ones to address the issues that we identified in our analysis. The quality of the code en-sured by the realized language and weaver has a positive impact both on maintenance effort and lead-time in the first line software development process. As evidence, we present a short evaluation of the language and weaver as applied today in the software development process of ASML. One of the primary goals of the Ideals project is to develop methods and tools to im-prove the handling of crosscutting concerns, such as tracing and profiling. As a so-lution, a proof-of-concept aspect-oriented [38] language for the C language [64] an
