Java

An FFM (Panama) wrapper over the C ABI. Construct a Radar from a JSON spec, then drive it with command(json) -> json.

<!-- Maven Central -->

</dependency>

import org.wickra.radar.Radar;

public final class Scan {
    public static void main(String[] args) {
        String spec = """
            {"symbols":["AAA"],
             "signals":[{"kind":"funding_flip","params":[0.0005],"weight":2.0}],
             "threshold":0.0}""";

        try (Radar radar = new Radar(spec)) {
            String response = radar.command("{\"cmd\":\"scan\",\"events\":{}}");
            System.out.println("wickra-radar " + Radar.version());
            System.out.println(response);
        }
    }
}

The binding uses the Java Foreign Function & Memory API, so it needs JDK 22+ and --enable-native-access.
