JTextPane output weird console characters

Question

I was trying to run console command in Kali linux, but the output are just weird when i pipe it to the JTextPane. When I diplay it on the output console of Netbean it was fine.

Command that I'm trying to run: wifite -e Experiment -c 1

code:

    public cracker(JTextPane aOutputPane)
      {
       super();
        mOutputPane = aOutputPane;
  }
  @Override
  protected String doInBackground() throws Exception
  {
    Process p = null;
    try
    {
        String Channel=CNinput.getText();
        String WName=WN.getText();
      p = Runtime.getRuntime().exec("wifite -e "+WName+" -c "+Channel);
    }
    catch (IOException ex)
    {
      Logger.getLogger(home.class.getName()).log(Level.SEVERE, null, ex);
    }
    BufferedReader buf = new BufferedReader(new InputStreamReader(p.getInputStream()));
    String line = "";
    String output = "";
    try
    {
      while ((line = buf.readLine()) != null)
      {
        publish(line);
        output += line + "\n";
      }
    }
    cat

ch (IOException ex)
    {
      Logger.getLogger(home.class.getName()).log(Level.SEVERE, null, ex);
    }
    try
    {
      p.waitFor();
    }
    catch (InterruptedException ex)
    {
      Logger.getLogger(home.class.getName()).log(Level.SEVERE, null, ex);
    }
    return output;
  }
  @Override
  protected void process(java.util.List<String> aChunks)
  {
    mOutputPane.setText(null);
    final String intermediateOutput = aChunks.stream().collect(Collectors.joining("\n"));
    final String existingText = mOutputPane.getText();
    final String newText = existingText + "\n" + intermediateOutput;
    mOutputPane.setText(newText);

  }

}

The characters are ANSI escape codes, intended to control the appearance of the terminal output generated by wifite. Among your options,

Elide the character sequences as they arrive in your implementation of doInBackground(); they all start with the ESC character.
Examine the codes and recapitulate the corresponding style in your JTextPane, as shown in the StyledDocument seen here.
Use a library such as the NetBeans console or Jansi, cited here.

After some googling with the thing you mentioned i find it useful, especially Jansi, is it possible to implement it to the .setText and how? I only find limited references on the system.out to AnsiConsole.systemInstall();. – Joco Tan Guan Min Mar 07 '17 at 20:07
I'm not sure that `Jansi` supports this usage directly, but it might be worth looking at how it does parsing. I've never needed more than a handful of `SimpleAttributeSet` instances in this context. – trashgod Mar 07 '17 at 23:47
How can I use SimpleAttributeSet with Jtextpanel, meaning like how would I allow the console pipe output to pipe formatted text into the jtextpanel? – Joco Tan Guan Min Mar 08 '17 at 07:19
You'd have to parse the code and apply the corresponding `SimpleAttributeSet`; sorry, I don't know a simpler approach. Because `JTextPane ` can display (limited) HTML, you might be able to leverage `HtmlAnsiOutputStream`, but I haven't tried it. – trashgod Mar 08 '17 at 12:50
