- split the xtask crate into structured modules for - bindings - ci - dev - util - no-std - Adding commands for - ci-release/ci-debug - MUSL/no-std - per- binding language smoke tests - developer tasks (fmt, clippy, pre-commit, pre-push) - refresh Cargo manifests/locks, binding readmes, and shared FFI helpers so every binding reuses the same preparation steps - refactor GitHub Actions (release/debug, extensions, CodeQL, clippy, bindings) to call the new xtask commands - Use rust-cache in ci workflows (microsoft qdk also does this) - extend README with a contributor workflow section describing how xtask mirrors CI expectations - update pre-commit and pre-push hooks to use the xtask dev commands WORKAROUND: When dotnet is run from an xtask, codeql tracer intercepts it an routes to a nonexistent binary. Therefore in codeql workflow, xtask is not used for c# and instead dotnet is directly invoked. Tracked by #545 closes #475 Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com>

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}}]}]}
