A Delta-Oriented Approach to Support the Safe Reuse of Black-Box Code Rewriters

The tedious process of corrective and perfective maintenance is often automated thanks to rewriting rules using tools such as Spoon or Coccinelle. These tools consider rules as black-boxes, and compose multiple rules by giving the output of a given rewriting as input to the next one. It is up to the developer to identify the right order (if it exists) among all the different rules. In this paper, we define a formal model compatible with the …
