Ultimate Automizer VS Code Extension

This extension runs a formal verification on the current active C file. It relies on Ultimate Automizer as external tool.

Features

A formal verification by Ultimate Automizer on the file is performed and the results are embedded into the VS Code diagnostics.

Requirements

Connection to a public server running Ultimate Automizer, e.g. https://ultimate.sopranium.de/api.

Alternatively a container providing the API can be executed inside Docker. A dockerfile to host the Backend locally can be found here.

Extension Settings

This extension contributes the following settings:

• ultimate.mode: "rest-api"/"stdout" to specify if Ultimate will be accessed by accessing a REST API or the output of the command line.
• ultimate.url: Base URL of the REST API endpoint.
• ultimate.refreshDelay: Refresh rate for polling results from REST API (limited to 3 seconds for known public APIs).
• ultimate.executablePath: Path to the executable of Ultimate is NOT accessed by the REST API. This can either be Ultimate itself or the wrapper script for MacOS.
• ultimate.settingsPath: Path to the settings (*.epf) of Ultimate is not accessed by the REST API.
• ultimate.toolchainPath: Path to the toolchain (*.xml) of Ultimate. A default toolchain is used if not defined.
• ultimate.verifyOnSave: Enables verification on each file save (false by default)

Known Issues

• Make sure the right Java version is used as default version if running Ultimate locally.
• Windows version only working tested using the REST API mode since Ultimate 0.2.3 was not working on my Windows test machine properly.
• The result representation (code highlighting, log output etc.) so far looks differently for rest-api and stdout mode. This is due to the output of Ultimate in the two different modes.
