Can't use backspace

[mainrs]

I made a video about it: https://youtu.be/WTO5t_LXCV0
I can't use backspace in a native shell on MAC OSX.

I am facing the same problem. And I have review the source code, it seems like the function of backspace didn't achieve the function of deleting character. Furthermore, I suppose to use the function of 'resetPromptLine' , but the logic of algorithm still wrong. Anyone have a good solution for this problem?

I have added some code in ConsoleReader.java to solve the backspace problem. The following solution basically solve the problem of backspace.
But there is problem that when I type quicker than computer, the action will pending. The backspace function can't work properly.
If anyone have better solution, please leave comments in this page.

case BACKWARD_DELETE_CHAR: // backspace
int bc = buf.cursor;
String bufbuffer = buf.buffer.toString();
String newbuf = bufbuffer;
if(!newbuf.isEmpty()){
newbuf = newbuf.substring(0, newbuf.length()-1)+" ";
setBuffer(newbuf.toString());
buf.buffer.replace(0, buf.buffer.length(), bufbuffer);
buf.cursor = bc;
flush();
}
success = backspace();
flush();
break;
