UTty

An advanced node.js tty class.

Introduction

We know that process.stdout in node.js is a WriteStream with tty support.

But there is a lot of troubles using the standard tty class, because some unsupported methods.

We can't do these things through standard tty:

• Get current cursor coordinate.
• Redraw a line that is not inside the screen.
• ...

So there is UTty, to solve these problems.

Theory

Utty is a proxy of a standard tty.

It records the current line according to the outputs.

CATION: current line ≠ current y!

name	differences
current line	Start as 0 when UTty is constructed
current y	We don't know what its value is. It is safe to only operate delta y
