What is the process for incorporating the hostname and current working directory into the xterm.js terminal with the use of node-pty in electron.js?

enter image description here

My objective is to modify the bash-3.2 with the current directory and hostname, creating an experience similar to that of VS Code's integrated terminal.

I am utilizing electron.js with xterm.js and node-pty for this purpose.

To spawn a node-pty process, I've attempted the following code:

  const ptyProcess = pty.spawn(shell, [], {
    name: 'xterm-color',
    cols: 80,
    rows: 30,
    cwd: process.env.CWD,
    env: process.env,
  });

To replace bash-3.2 with the hostname and current working directory like in VS Code's integrated terminal, you can set the name option for node-pty to a function that returns the desired string based on the current working directory and hostname. Here's an example: 
const ptyProcess = pty.spawn(shell, [], {
  name: () => {
    const cwd = process.cwd();
    const hostname = os.hostname();
    return `${cwd} [${hostname}]`;
  },
  cols: 80,
  rows: 30,
  cwd: process.env.CWD,
  env: process.env,
});
In this example, we've set the name option to a function that uses the process.cwd() method to get the current working directory and the os.hostname() method to get the hostname. The function returns a string with the desired format, which is ${cwd} [${hostname}]. This will display the current working directory followed by the hostname in square brackets as the terminal prompt.
