Release the core `regorus` crate as v0.11.0 (up from v0.10.1) and align every language binding to the same version. This release carries an API-breaking change (flagged by cargo-semver-checks), so it takes a minor bump under the 0.x SemVer convention. Highlights since v0.10.1: - fix(rvm): assert every-quantifier results so failing cases don't pass (#765) - fix: deep-merge nested data documents in Engine::add_data (#760) - feat(compiler): support registered host-await builtins for natural function call syntax (#667) - feat(value): introduce Set/Object storage abstractions (#740, #735, #736) - security: reject data nested beyond 128 levels to avoid stack overflow Version updates: - Core crate (Cargo.toml/Cargo.lock) 0.10.1 -> 0.11.0 - Bindings aligned via `cargo xtask bindings`: ffi, java, python, wasm, ruby, csharp (manifests, lockfiles, pom.xml, Directory.Packages.props, version.rb) - CHANGELOG.md updated with the 0.11.0 section
Regorus Java
Regorus is
- Rego-Rus(t) - A fast, light-weight Rego interpreter written in Rust.
- Rigorous - A rigorous enforcer of well-defined Rego semantics.
See main Regorus page for more details about the project.
Building
Due to operational overhead we don't publish Java bindings to Maven Central currently (see https://github.com/microsoft/regorus/issues/237) and you need to build from source to use it.
In order to build Regorus Java for a target platform, you need to install Rust target for that platform first:
$ rustup target add aarch64-apple-darwin
Afterwards, you can build native library for that target using:
$ cargo build --release --target aarch64-apple-darwin
You will then have a native library at target/aarch64-apple-darwin/release/libregorus_java.dylib depending on your target.
You then need to build Java bindings using:
$ mvn package
And you will have a JAR at ./target/regorus-java-0.1.5.jar.
Automation
The repository exposes helper commands for local workflows:
cargo xtask build-javarunsmvn packagewith quiet output helpers.cargo xtask test-javarebuilds the native library via the Maven exec plugin and executes the binding tests.
Usage
You can use Regorus Java bindings as:
import com.microsoft.regorus.Engine;
public class Test {
public static void main(String[] args) {
try (Engine engine = new Engine()) {
engine.addPolicy(
"hello.rego",
"package test\nmessage = concat(\", \", [input.message, data.message])"
);
engine.addDataJson("{\"message\":\"World!\"}");
engine.setInputJson("{\"message\":\"Hello\"}");
String resJson = engine.evalQuery("data.test.message");
System.out.println(resJson);
}
}
}
You need to ensure artifacts built in previous section are in Java's classpath.
For example with java CLI:
$ java -Djava.library.path=../../target/aarch64-apple-darwin/release/ -cp target/regorus-java-0.1.5.jar Test.java
should gave you the output:
{"result":[{"expressions":[{"value":"Hello, World!","text":"data.test.message","location":{"row":1,"col":1}}]}]}
