Tursi is a simulator for deterministic single-tape Turing machines. I started it in 2013 at the end of my first semester to replace an outdated applet we were using in a lecture.

By now, Tursi seems rater outdated itself. However, I publish it here in the hope that it will be useful to someone.

• Cross-platform Java application
• Debug Turing machines with history and break states
• Export transition tables to state diagrams
• Fast console mode for time-consuming Turing machines
• Compact transition tables using wildcards

• Download the .jar file from the latest release.
• Install a Java Runtime Environment (JRE 8 or higher) if you haven't already.
  • Windows users should be able to start it by simply double clicking the .jar file.
  • Linux users may have to make the file executable first
    or start it from the console using java -jar /path/to/Tursi.jar.

There is a comprehensive tutorial and a manual on Tursi's website. For a quick start you may also want to look at the examples in the download section.

Tursi's first version was written in Java 1.6. Tursi itself hasn't changed much since then, but I made sure that it can be compiled flawlessly with newer Java versions. Tursi's current version was tested with Java 8 to 13. To compile it yourself ...

• Install a Java Development Kit (JDK 8 or higher) and Apache Ant if you haven't already.
• Open a terminal in this repo's root directory and run ant. This will create the file bin/Tursi.jar.
