Minecraft Java Pretty Print to Discord, Console & File Asynchronously

README.md

Replace

Replace OskaRPG to your JavaPlugins instance. and getLoggerFolder is function for getting File object. You can use your own File instance.

Example

public class Example {
  
  public static Logger log = new Logger("Example");
  
  public void actionWithException() throws Exception {
    throw new Exception();
  }
  
  public static void main() {
    log.withTracker(() -> actionWithException());
    log.toDiscord("some message", null);
    log.toDiscord("some error", new Exception());
    log.toFile("some message", null);
    log.toFile("some error", new Exception());
    log.toConsole("some message", null);
    log.toConsole("some error", new Exception());
  }
}
