What is KeY?

KeY

KeY is a super user-friendly app designed to help you check proof files for Java tools. It’s mainly for developers, so a bit of Java knowledge really helps!

Easy Setup Process

The setup is quick and straightforward. You’ll be guided to download some libraries and put them in a specific folder. This step is crucial for everything to work smoothly.

Launching KeY

Once you’ve got the libraries in place, it's time to get KeY running! Just use a BAT file to launch it and load your proof file into the app for verification based on rules you can change.

Working with Proof Files

To open an object in the application, simply choose the right option from the ‘File’ menu. You’ll see the proof tree pop up in a panel, showing your ‘Current Goal’. Pretty neat, right?

Customizing Your Verification Process

Next up, head over to the ‘Proof Search Strategy’ tab. Here’s where you can set your rules for verification! Options include ‘Java DL Options’, ‘Proof Splitting’, ‘Loop Treatment’, and more. You can even define how many times rules should apply—anywhere from one time up to a million!

Starting Verification

When you're ready, hit that ‘Start’ button! KeY will verify your proof file and show you the results in a popup window. Once done, you can save the generated PROOF format file right onto your computer.

A Quick Summary of KeY

In short, KeY is a handy and lightweight tool that Java programmers can use to verify their proof files quickly. Plus, it lets you tweak things just how you want them!
