package picocli.jansi.graalvm;

/**
 * Enables the use of Jansi native library code in GraalVM native image applications.
 * 
 * This class provides a workaround for a problem in Jansi's
 * org.fusesource.hawtjni.runtime.Library
 * that prevents the native libraries embedded in the Jansi JAR in
 * /META-INF/native/* from being loaded
 * when running in a GraalVM native image.
 * 
 * 
 * Usage: call {@code Workaround.enableLibraryLoad()} before calling any Jansi code.
 * For example:
 * 
 *  * import org.fusesource.jansi.internal.WindowsSupport;
 * import picocli.jansi.substratevm.Workaround;
 *
 * public class OtherApp {
 *
 *     static {
 *         Workaround.enableLibraryLoad();
 *     }
 *
 *     public static void main(String[] args) {
 *         int width = WindowsSupport.getWindowsTerminalWidth();
 *         doCoolStuff(width);
 *     }
 *     // ...
 * }
 *
