Interactive Simplifier Tracing and Debugging in Isabelle

  • Lars Hupel
Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 8543)


The Isabelle proof assistant comes equipped with a very powerful tactic for term simplification. While tremendously useful, the results of simplifying a term do not always match the user’s expectation: sometimes, the resulting term is not in the form the user expected, or the simplifier fails to apply a rule. We describe a new, interactive tracing facility which offers insight into the hierarchical structure of the simplification with user-defined filtering, memoization and search. The new simplifier trace is integrated into the Isabelle/jEdit Prover IDE.
