We present the R 2 D 2 redundancy detector. R 2 D 2 identifies redundant code fragments in large software systems written in Lisp. For each pair of code fragments, R 2 D 2 uses a combination of techniques ranging from syntax-based analysis to semantics-based analysis, that detects positive and negative evidences regarding the redundancy of the analyzed code fragments. These evidences are combined according to a well-defined model and sufficiently redundant fragments are reported to the user. R… CONTINUE READING
