Venice is a Clojure inspired sandboxed Lisp dialect with excellent Java interoperability.
Venice is a Lisp dialect born from the need for a safe, sandboxed, general-purpose language. It shares with Lisp the code-as-data philosophy and a powerful macro system.
Venice is mainly a functional programming language focusing on immutable, persistent data structures.
Venice supports macros, tail-recursion, dynamic code loading, multimethods, protocols and many more. It comes with excellent Java interoperability, and a configurable sandbox that can prevent all sorts of unwanted JVM and Venice interactions. Venice has been designed from the ground-up with a sandbox, making it a first class citizen.
Venice includes a comprehensive library of over 900 core functions. Its immutable persistent data structures, along with Clojure-style atoms, futures, promises, and agents, greatly simplify the process of writing concurrent code.
Venice seamlessly and transparently integrates with Java and any third-party libraries, giving you access to a vast array of libraries, frameworks, and tools.
Venice's strength is making complex scripting tasks easy. Have you ever felt limited by Bash or PowerShell scripts? With Venice, you can write concise and elegant platform independent scripts effortlessly.
Venice does not depend on any runtime libraries (other than the JVM). You can easily add it as a standalone JAR to your classpath.
Venice requires Java 8 or newer.

You can can pull it from the central Maven repositories:
<dependency>
<groupId>com.github.jlangch</groupId>
<artifactId>venice</artifactId>
<version>1.12.35</version>
</dependency>
From a command shell, run ./gradlew shadowJar in the project home dir, to invoke the Gradle task to build the Venice JAR.
On MacOS / Linux
Give gradlew execute permission after cloning the Venice git repository ...
venice% chmod +x ./gradlew... and build the project
venice% ./gradlew clean shadowJarOn Windows
C:\Users\foo\venice> gradlew.bat clean shadowJar
I accept Pull Requests via GitHub. There are some guidelines which will make applying PRs easier for me:
- No tabs! Please use spaces for indentation.
- Respect the existing code style for each file.
- Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
- Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running gradle.
