Limboole Extension for Visual Studio Code

Limboole is a tool for checking satisfiability and tautology in arbitrary structural boolean formulas, and can also translate these problems into CNF. For more information, see the Limboole website.

If you prefer to use Limboole online, you can use the FM Playground. It offers a web interface for Limboole and other formal methods tools.

Features

This extension allows you to run Limboole from within Visual Studio Code.

Usage

For .limboole files, you can check satisfiability and validity of the formula by clicking on the ▶ Check SAT and ▶ Check VAL buttons in top left corner of the editor. The result will be displayed in the output window. For other file types e.g. .txt, you can run Limboole by opening the command palette (Ctrl+Shift+P) and typing Limboole: .... You can check satisfiability, validity, and CNF translation of the formula.
