This is ViperServer, an HTTP server that manages verification requests to different tools from the Viper tool stack.

The main two Viper tools (a.k.a verification backends) currently are: 

- [Carbon](https://github.com/viperproject/carbon), a verification condition generation (VCG) backend for the Viper language.  

- [Silicon](https://github.com/viperproject/silicon), a symbolic execution verification backend.  

### The Purpose of ViperServer ###

1. Viper IDE: integration of Viper into Visual Studio Code (VS Code). Viper IDE provides the best user experience for Viper.

   More details here: http://viper.ethz.ch/downloads/

1. Facilitate the development of verification IDEs for Viper frontends, such as: 

    - [Gobra](https://github.com/viperproject/gobra), the Viper-based verifier for the Go language

    - [Prusti](https://github.com/viperproject/prusti-dev/), the Viper-based verifier for the Rust language

1. Avoid 1-3 second delays caused by JVM startup time. ViperServer offers a robust alternative to, e.g.,

   [Nailgun](https://github.com/facebook/nailgun).

1. Develop Viper encodings more efficiently with caching.

1. Interact with Viper tools programmatically using the HTTP API. A reference client implementation (in Python) is

   available via [viper_client](https://github.com/viperproject/viper_client).

### Installation Instructions ###

* Clone **viperserver** (this repository) in your computer.

* Execute `git submodule update --init --recursive` in the cloned directory to fetch the `carbon`, `silicon`, and (transitively) the `silver` repositories. Note that both `carbon` and `silicon` have a `silver` submodule. Even though `silicon`'s `silver` repository is actually used for compilation of ViperServer, we assume that both reference the same `silver` commit.

* Compile by typing: ```sbt compile```

* Other supported SBT commands are: ```sbt stage``` (produces fine-grained jar files), ```sbt assembly``` (produces a single fat jar file).

### Running Tests ###

* Set the environment variable ```Z3_EXE``` to an executable of a recent version of [Z3](https://github.com/Z3Prover/z3).

* Run the following command: ```sbt test```.
