How to set the size of the buffer in xtermjs?

Question

I know I can clear the buffer. by .clear() method. But can I restrain the size of the buffer in terms of memory or number of lines? Can somebody help me on this or point to the docs? Because in docs I am not able to find a clear solution.

Bit Late, hope this could still help.

The Terminal object contains a reference to buffer, you can access a property x & y, which you can limit against.

x = number of characters on a line y = number of lines

You could try something like this

const maxBufferLines = 10;
terminal.on('key', (key, ev) => {

  if (ev.keyCode === 13) {

    if (terminal._core.buffer.y >= maxBufferLines) {
      terminal.writeln('Max Buffer Size');
    } else {
      terminal.write('\r\n$ ');

    }
  }
});
