Toward Reusing Code Changes

Existing techniques have succeeded to help developers
implement new code. However, they are insufficient to help to
change existing code. Previous studies have proposed techniques
to support bug fixes but other kinds of code changes such
as function enhancements and refactorings are not supported
by them. In this paper, we propose a novel system that helps
developers change existing code. Unlike existing techniques, our
system can support any kinds of code changes if similar code
changes occurred in the past. Our research is still on very early
stage and we have not have any implementation or any prototype
yet. This paper introduces our research purpose, an outline of our
system, and how our system is different from existing techniques.
