Title: Generic Tactic Tracing in Isabelle
Speaker: Gunther Bidlingmaier
Type: Bachelor's Thesis Presentation

Abstract:

A core part of the Isabelle proof assistant is the simplifier tactic, which  
subsequently applies rewrite rules from left to right in order to  
automatically simplify terms and thereby proof propositions. Since the  
simplifier is an essential part of Isabelle, it is often important to gain  
insights into the simplification process and why or why not a specific term  
was produced.

While the simplifier provides a built-in tracing facility, the produced  
traces do not map to the recursive structure of the simplification  
attempts, making it difficult to comprehend the basic procedure of the  
simplifier. This problem is further aggravated by the often huge size of  
the traces and the limited options for filtering the information.

An external tracing facility providing structure, interactivity and  
influence over the simplification has been developed by Hupel [1] for  
Isabelle/jEdit. This tracing system however does not cover all relevant  
information provided by the simplifier. Furthermore the interactivity of  
the system proved to be impractical for everyday usage.

This thesis builds upon the newer tracing facility and the experience  
gained from its usage: It extends the system to cover all relevant  
information, heavily simplifies its architecture and user interface by  
removing interactivity and adapts the filtering system to meet the  
requirements of the extended and modified tracing.
