TTY

Use require('tty') to access this module.

Example:

var tty = require('tty');
tty.setRawMode(true);
process.stdin.resume();
process.stdin.on('keypress', function(char, key) {
  if (key && key.ctrl && key.name == 'c') {
    console.log('graceful exit');
    process.exit()
  }
});

tty.open(path, args=[])

Spawns a new process with the executable pointed to by path as the session leader to a new pseudo terminal.

Returns an array [slaveFD, childProcess]. slaveFD is the file descriptor of the slave end of the pseudo terminal. childProcess is a child process object.

tty.isatty(fd)

Returns true or false depending on if the fd is associated with a terminal.

tty.setRawMode(mode)

mode should be true or false. This sets the properties of the current process's stdin fd to act either as a raw device or default.

tty.setWindowSize(fd, row, col)

ioctls the window size settings to the file descriptor.

tty.getWindowSize(fd)

Returns [row, col] for the TTY associated with the file descriptor.
