A Complete Declarative Debugger for Maude

摘要

We present a declarative debugger for Maude specifications that allows to debug wrong answers (a wrong result is obtained) and missing answers (a correct but incomplete result is obtained) due to both wrong and missing statements and wrong search conditions. The debugger builds a tree representing the computation and guides the user through it to find the bug. We present the debugger's latest commands and features, illustrating its use with several examples.
