<h1>Proof Script Debugger for the KeY System</h1>
# Proof Script Debugger for the KeY System
<p>The proof script debugger is a prototypical implementation
The proof script debugger is a prototypical implementation
of an interaction concept for program verification systems that are rule based and
use a program logic.
The prototype is implemented on top of the interactive program verification system
<a href="http://www.key-project.org">KeY</a>. KeY is an interactive program verification
[KeY](http://www.key-project.org. KeY is an interactive program verification
system for Java program annotated with the Java Modeling Language (JML).
</p>
<p>
The protypical implementation includes a proof scripting language that is tailored to the
problem domain of program verification.
The main features of the language are:
<ol>
<li> integration of domain specific entities like goal, formula, term and rule as
1. integration of domain specific entities like goal, formula, term and rule as
first-class citizens into the language;</li>
<li> an expressive proof goal selection mechanism
<ul>
<li>to identify and select individual proof branches,</li>
<li>to easily switch between proof branches,</li>
<li>to select multiple branches for uniform treatment (multi-matching);</li>
</ul>
that is resilient to small changes in the proof</li>
<li> a repetition construct which allows repeated application of proof strategies;</li>
<li> support for proof exploration within the language.</li>

1. support for proof exploration within the language.</li>
</ol>
Together with the proof scripting language a debugging concept for failed proof attempts
is implemented that leverages well-known concepts from program debugging to
the analysis of failed proof attempts.
