    Kammerjäger

    Kammerjäger is a debugging tool with integrated correctness proving.

    Kammerjäger is a debugging and testing tool that enables you to prove the correctness of your code. In our C like programming language named "SimPL" you can easily and simply annotate your code with preconditions and assertions (also with forall and exists expressions). We then use Microsofts Z3 theorem prover to prove if the behaviour of your program matches what you expected. The easy to use GUI with an integrated Interpreter and Debugger (with a Stackview and HotCodeReplacement) makes it even easier to write your code and find errors. This project has been developed during a University project called PSE ("Praxis der Softwareentwicklung" / "practical experience in software developement") at the Karlsruhe Institute of Technology (KIT) by Andreas Eberle, Nicolas Loza, Olga Plisovskaya, Andreas Waidler and Michael Zangl.
