Requirements

Sonic Pi installed and running (for live execution)

How live execution works

The extension reads the port and session token directly from the running Sonic Pi process — no manual configuration needed. It works on Windows (via WMI), macOS and Linux (via ps//proc).

Known limitations

Live execution requires Sonic Pi to be already open
The extension registers as a language for .rb files — if you also use a Ruby extension, IntelliSense may offer both providers
