Walk Your Tree Any Way You Want

Anya Helene Bagge and Ralf Lämmel

Abstract. We describe a new approach to software transformation, which is inspired by strategic and adaptive programming, though without starting from the same kind of separation between traversal specification and actions to be applied along traversal. Instead, transformations are described as walks that proceed in programmer-defined steps which may observe join points of a traversal, may affect state associated with the walk, may rewrite the walked tree, and must walk somewhere. The approach blends well with OO programming. We have implemented the approach in the Nuthatch/J library for Java.
