Java

An FFM (Panama) wrapper over the C ABI. Construct a Terminal from a JSON config, then drive it with command(json) -> json — subscribe a symbol, then tick.

import org.wickra.terminal.Terminal;

public final class Frame {
    private static final String CONFIG =
        "{\"sources\":[{\"Synth\":{\"seed\":1}}],"
        + "\"layout\":{\"panels\":[{\"kind\":\"Chart\",\"rect\":{\"x\":0,\"y\":0,\"w\":100,\"h\":100}}]}}";

    public static void main(String[] args) {
        try (Terminal term = new Terminal(CONFIG)) {
            term.command("{\"type\":\"Subscribe\",\"source\":0,\"symbol\":\"BTC/USDT\"}");
            String raw = "";
            for (int i = 0; i < 20; i++) {
                raw = term.command("{\"type\":\"Tick\"}");
            }
            System.out.println("wickra-terminal " + Terminal.version());
            System.out.println(raw);
        }
    }
}

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