This VS Code extension provides interactive IDE features for Viper — the Verification Infrastructure for Permission-based Reasoning.
The extension automatically downloads and manages Viper (via publicly available links, as listed here: http://viper.ethz.ch/downloads/).
Viper IDE uses an open-source 64-bit Java server, so you need Java (version 11 or newer) installed to be able to run it.
Please always refer to the official installation instructions for more details (in particular, about different operating system support).
